Unless otherwise indicated, all years referred to in this study are federal fiscal years (which run
from October 1 to September 30).
Unless otherwise indicated, all dollar amounts in this study are expressed in 2011 dollars.
Before providing cost data to the Congressional Budget Office (CBO), the Veterans Health
Administration converted those data to fiscal year 2009 dollars on the basis of annual
increases in the average cost of a primary care visit from 2004 to 2009. CBO indexed those
data to 2011 dollars using the implicit price deflator for gross domestic product. CBO also
converted other dollar amounts reported in this study to 2011 dollars using the implicit price
deflator for gross domestic product.

Preface
CBO
Two combat-related conditions that affect some veterans who have served in Iraq and
Afghanistan and that have generated widespread concern among policymakers are post-
traumatic stress disorder (PTSD) and traumatic brain injury (TBI). In response to a request
from the Ranking Member of the House Committee on Veterans’ Affairs, this Congressional
Budget Office (CBO) study examines the following:
•The clinical care that the Veterans Health Administration (VHA), the health care
system within the Department of Veterans Affairs, provides for recent combat veterans;
•VHA’s coordination with the Department of Defense for the care of service members
returning from Iraq and Afghanistan;
•The prevalence of PTSD and TBI among veterans of those conflicts and the occurrence
of those conditions among recent combat veterans using VHA’s services; and
•The costs to VHA of providing care to recent combat veterans for those conditions.
In keeping with CBO’s mandate to provide objective, impartial analysis, this study makes no
recommendations.
Elizabeth Bass and Heidi Golding of CBO’s National Security Division prepared the study
under the general supervision of David Mosher and Matthew Goldberg. Allison Percy
served as the internal reviewer. Lindsay Coleman, Juan Contreras, Sunita D’Monte, and

Summary
More than 2 million service members have
deployed in support of overseas contingency operations
(OCO) in Iraq and Afghanistan since October 2001.
Some military service members receive medical care in
the combat theater for injuries or other medical condi-
tions sustained while deployed. Other service members
have combat-related medical conditions that are identi-
fied and treated after they return from war—within the
Department of Defense’s (DoD’s) health care system for
active-duty personnel and within the Department of
Veterans Affairs (VA) for veterans, including deactivated
reservists. VA provides health care services through the
Veterans Health Administration (VHA), which treats
veterans for service-connected conditions and other
conditions.
VHA spent about $2 billion (in 2011 dollars) in fiscal
year 2010 to treat veterans of recent overseas contingency
operations, compared with total expenditures in 2010 on
health care for veterans of all eras and conflicts of about
$48 billion. From 2002 through 2010, VHA spent a total
of $6 billion on health care expenditures for recent OCO
veterans.
Two conditions that affect some military service
members during deployment to a combat theater and
afterward are post-traumatic stress disorder (PTSD) and
traumatic brain injury (TBI). PTSD is an anxiety disor-
der induced by exposure to a traumatic event, such as
witnessing injury or death. It is characterized by symp-
toms that include reexperiencing the event, hyperarousal
(irritability, anger, or hypervigilance, for example), and
diminished responsiveness to or avoidance of stimuli
associated with the trauma.
TBI is caused by sudden trauma to the head and is com-
monly sustained by soldiers exposed to explosions. It may
result in a decreased level of consciousness, amnesia, or
neurological abnormalities, and it is classified as mild,
moderate, or severe on the basis of its severity at the time
of the injury. Mild TBI, which is also known as a concus-
sion, may in some cases lead to ongoing symptoms that
include headaches, memory difficulties, fatigue, irritabil-
ity, and sleep problems. Diagnosing severe cases is
straightforward, but mild TBIs—which account for
about 90 percent of TBI cases among active-duty OCO
service members—may be difficult to detect, both by
those afflicted and by health care professionals, although
most cases resolve quickly without medical intervention.1
Some observers contend that DoD and VHA may not
adequately screen, diagnose, and treat OCO service
members and veterans affected by PTSD and mild TBI.
In this study, the Congressional Budget Office (CBO)
analyzes VHA’s care of OCO patients diagnosed with
PTSD or TBI and compares the reported rates of occur-
rence of those conditions within VHA with estimates of
the prevalence of those conditions in the broader popula-
tion of service members who have deployed to recent
overseas contingency operations. (Prevalence estimates
gauge the proportion of cases of a disease or condition in
a population, whether or not people have received a diag-
nosis from a medical professional; by comparison, the
reported occurrence of conditions among the people
who have been treated within VHA reflects counts of
diagnoses by medical professionals.) The study also exam-
ines the costs that VHA has incurred in treating patients
diagnosed with PTSD and TBI.
1. Diagnosis of mild TBI with persistent symptoms is complicated
because the condition does not have a clinically validated defini-
tion—that is, a definition that is based on a substantive body of
empirical research and is broadly accepted by the medical commu-
nity. Moreover, many other conditions cause symptoms that are
similar to those of mild TBI.

The First Year of Treatment for All Health Care Provided to

Source: Congressional Budget Office based on data from the Department of Veterans Affairs, Veterans Health Administration.
Notes: Data cover fiscal years 2004 to 2009 for the first year of treatment.
All of the TBI patients in the data that CBO examined had symptomatic TBI—that is, they exhibited symptoms that were attributed to
TBI at the time of VHA’s medical screening or examination.
VHA converted costs provided to CBO to fiscal year 2009 dollars on the basis of annual increases in the average cost of a primary care
visit from 2004 to 2009. CBO then indexed those costs to 2011 dollars using the implicit price deflator for gross domestic product.
OCO = overseas contingency operations; VHA = Veterans Health Administration; PTSD = post-traumatic stress disorder;
TBI = traumatic brain injury; * = less than 1 percent.
a. Patients in the PTSD group did not have TBI, but many had other conditions.
b. Patients in the TBI group did not have PTSD, but many had other conditions.
In brief, CBO finds:
Among OCO patients treated by VHA from 2004
through 2009, 21 percent were diagnosed with PTSD
(but not TBI) and 2 percent with symptomatic TBI
(but not PTSD) (see Summary Table 1).2 An addi-
tional 5 percent had both PTSD and TBI; thus, about
75 percent of those diagnosed with TBI had a con-
current diagnosis of PTSD. Seventy-two percent of
patients had neither diagnosis. (CBO separately
analyzed another 500 polytrauma patients—that is,
ones with complex, severe injuries to multiple organ
systems.)
The average cost for OCO patients in the first year of
their treatment was about four to six times greater for
patients with a diagnosis of PTSD, TBI, or both than
for patients without those conditions.
VHA’s average costs for OCO patients were highest
during the first year of care and generally declined and
then stabilized in subsequent years.
For patients with TBI (including those with both
PTSD and TBI), however, VHA’s average treatment
costs appear to increase in the third and fourth years of
care. That result is probably driven by a policy change
that occurred in the middle of the period that CBO
analyzed and the nature of the data that VHA pro-
vided to CBO.3 In the absence of the policy change,

ination.
3. VHA’s clinical practices for TBI changed during the data period
(2004 to 2009): In 2007, the agency initiated comprehensive
screening for mild, symptomatic TBI. Therefore, patients whom
VHA diagnosed with TBI in 2007 or later were more likely to
have had mild TBI than those diagnosed before that year. As a
result, the data that CBO analyzed included a smaller share of
patients with mild TBI in their third and fourth years of treat-
ment than in their first and second years. Because treating patients
with moderate or severe TBI requires more extensive services and
resources than does treating patients with mild TBI, that differ-
ence elevated the estimated average costs of treatment for TBI
patients in the third and fourth years.

CBO
costs for those patients probably also would have been
highest during the first year of care and then declined
and stabilized thereafter.
A great deal of uncertainty surrounds the prevalence of
PTSD and TBI within the OCO population and,
hence, the number of veterans with those conditions
that DoD, VHA, and other health care providers may
encounter in the future.
Projecting the future costs of treating veterans with
PTSD and TBI requires estimating both the number
of patients with those conditions who will seek VHA’s
care and the costs per patient that VHA will incur.
Because the research community has not reached a con-
sensus about the prevalence of those conditions, such
projections would be highly uncertain. CBO examined
published studies that reported the prevalence of PTSD
or TBI among different groups of service members or
veterans who had deployed to overseas contingency
operations. For PTSD, those prevalence estimates have
generally ranged between 5 percent and 25 percent. For
TBI, those estimates indicate that between 15 percent
and 23 percent of service members may have experienced
a TBI while deployed to an overseas contingency opera-
tion but that a smaller share, between 4 percent and
9 percent, are still symptomatic when screened after
returning to the United States. Estimates of the preva-
lence of PTSD and TBI vary widely among studies
because of substantial differences in the assessment tools
that researchers use to identify the conditions, the strin-
gency of the criteria they employ, and the subgroups
they sample. The percentage of OCO veterans whom
VHA clinicians have diagnosed with PTSD (26 percent)
is at the top of the range reported in published studies,
whereas the percentage they have diagnosed with symp-
tomatic TBI (7 percent) is in the middle of the
reported range.
The rates of diagnosis of PTSD and TBI among OCO
veterans seeking treatment at VHA do not necessarily
reflect the prevalence of those conditions in the entire
OCO population. If veterans who suspected they had
mental health or other medical problems were more likely
than other veterans to seek medical care from VHA, the
rates of PTSD and TBI diagnosed among VHA’s patients
would tend to overestimate the prevalence in the entire
OCO population. However, some veterans might not
seek care from VHA for various reasons—the stigma
associated with having a mental health problem, for
example, or the inconvenience of undergoing additional
evaluation and treatment. If a sufficient number of veter-
ans with PTSD and TBI did not seek care from VHA,
the rates of diagnoses for those conditions among VHA’s
patients would tend to underestimate the prevalence in
the OCO population.

The Veterans Health Administration’s Treatment of
PTSD and Traumatic Brain Injury Among
Recent Combat Veterans
Introduction
The United States has been involved in overseas contin-
gency operations (OCO) in Afghanistan and Iraq since
October 2001 and March 2003, respectively, and has
deployed more than 2 million service members in sup-
port of those operations. The Department of Defense
(DoD) delivers medical care to service members while
they are deployed. That care includes nearly 4 million
medical encounters since January 2005 for a variety of
conditions, including injuries; it also includes 71,000
medical evacuations of service members from the combat
theaters through November 2011. Both DoD and the
Veterans Health Administration (VHA), the organization
that provides medical care within the Department of
Veteran Affairs (VA), screen for various conditions and
provide health care after service members return from
deployment. VHA treated 400,000 (31 percent) of
1.3 million eligible OCO veterans in fiscal year 2010,
up from 100,000 (20 percent) of 500,000 eligible OCO
veterans in 2005. Many eligible veterans do not seek care
at VHA in any given year or at any time, and most VHA
patients seek additional health care outside of VHA. (See
Box 1 for information about eligibility for VHA’s health
care system.) Although OCO veterans made up 7 percent
of the patients VHA treated in 2010, they accounted for
only 4 percent ($2 billion) of the $48 billion (in 2011
dollars) that VHA obligated for medical care that year.
From 2002 through 2010, VHA spent a total of
$6 billion on health care for OCO veterans.1
Two medical conditions that may affect OCO veterans
have received particular attention: post-traumatic stress
disorder (PTSD) and traumatic brain injury (TBI).
PTSD is an anxiety disorder triggered by a traumatic
event, such as may occur when engaging in combat;
witnessing serious injury, brutality, or unnatural death,
particularly of another soldier; or suffering a severe
vehicle accident, including those caused by improvised
explosive devices (IEDs). The symptoms of PTSD
include reexperiencing the event, hyperarousal (irritabil-
ity, anger, or hypervigilance, for example), and dimin-
ished responsiveness to or avoidance of stimuli associated
with the trauma. TBI is a blow to the head that alters a
person’s consciousness, if only momentarily. TBI may
result in amnesia or neurological abnormalities at the
time of injury. In the combat theater, explosions from
IEDs or other bombs are a leading cause of TBI among
military personnel, although TBIs also result from falls,
motor vehicle accidents, and bullet wounds.2 TBI is
classified as mild, moderate, or severe on the basis of
its severity at the time of injury. (That classification
refers to the acuteness of initial symptoms only, not
to that of persistent symptoms.) Mild TBI, also known
as a concussion, typically resolves quickly without
medical treatment, in many cases within weeks and
in most cases within three months. Although some
symptoms may linger for six months or more, there
is considerable debate over whether those persistent
symptoms can be attributed to mild TBI or to other

L. W. Golding, Principal Analyst for Military and Veterans’
Compensation, Congressional Budget Office, before the Senate

conditions.3 (See Appendix A for more detailed informa-
tion about PTSD and TBI.)
Few service members have been evacuated from combat
theaters as a result of PTSD or TBI alone, although many
have been evacuated for TBI in conjunction with other
injuries. Many cases of PTSD and TBI may go unrecog-
nized and consequently undiagnosed and untreated, both
in the combat theater and once the service member
returns home. PTSD can interfere with daily functioning
when it results in emotional withdrawal from family and
friends, inappropriate expressions of anger, irritability,
overprotective behaviors, or substance abuse. Those with
ongoing mild TBI may feel sad, nervous, or agitated;
have difficulty concentrating and sleeping; and experi-
ence sensitivity to noise or light. Those with moderate
or severe TBI may experience similar difficulties but
also have more complex physical and neurological limita-
tions, which in some cases affect their ability to live
Box 1.
Eligibility for VHA’s Services
Eligibility for the health care system of the Veterans
Health Administration (VHA) is based primarily on a
veteran’s military service. Generally, veterans of the
active components of the military must have served
24 continuous months on active duty to be eligible;
reservists and National Guard members may be
eligible if they are called to active duty under a federal
order and they complete that service. Those broad
criteria, however, do not necessarily guarantee access
to medical treatment. VHA operates an enrollment
system that assigns a veteran to one of eight categories
to establish his or her priority for using its health
care services. Veterans with higher priority include
those who have service-connected disabilities, low
income, or both. In January 2003, VHA imposed a
general freeze (with some subsequent modifications)
on new enrollments in the lowest priority group
(Priority Group 8).1
The Veterans Programs Enhancement Act of 1998
(Public Law 105-368) guarantees access to VHA’s
health care system, after separation from active mili-
tary service, to members of the armed forces who
have served on active duty in combat operations since
the law was enacted in November 1998; reservists
and members of the National Guard who have served
in combat operations are also included under that
guarantee. The law gave combat veterans two years
(starting from their date of separation from the mili-
tary) to enroll and use VHA’s health care system with-
out requiring those veterans to document either that
their income is below established thresholds or that
they have a service-connected disability—require-
ments that noncombat veterans must fulfill. In 2008,
lawmakers extended the enhanced eligibility period
for care through VHA’s health care system to five
years.2 Under those legislative authorities, VHA pro-
vides free health care for medical conditions directly
or potentially related to a veteran’s military service in
combat operations for five years after separation.
Veterans who had deployed to overseas contingency
operations (OCO) may continue to use VHA’s ser-
vices when the five-year period of enhanced eligibility
ends, but their priority group for enrollment may
change, depending on their disability status and
income. In particular, OCO veterans may be moved
to a lower priority group, including Priority Group 8,
and incur the applicable copayments.
1. Veterans in Priority Group 8 are those who have no service-
connected disabilities (or, according to a determination by
the Department of Veterans Affairs [VA], have service-
connected disabilities that are ineligible for monetary com-
pensation) and have annual income or net worth above VA’s
means-test threshold and regional income threshold. See

independently. Symptoms manifest themselves in differ-
ent ways and with different intensity across people and
situations; some people function well in some settings but
not in others.
Some policymakers have questioned whether DoD and
VHA have the resources and capacity to serve the OCO
population with PTSD and TBI. Some observers are also
concerned about whether service members and veterans
with those conditions are reluctant to seek the help they
need. In this study, the Congressional Budget Office
(CBO) examines the clinical care provided by VHA for
OCO veterans with PTSD and TBI, VHA’s coordination
with DoD for the care of service members and veterans,
the rate of occurrence of PTSD and TBI among VHA
patients and the estimated prevalence of those conditions
in the broader population of recent OCO veterans, the
use of VHA’s health care services by OCO veterans who
have been diagnosed with PTSD or TBI, and the costs of
providing that care. Because the prevalence of PTSD and
TBI in the OCO population is highly uncertain, CBO
has not projected VHA’s future costs for treating veterans
with those conditions.
Clinical Care Within VHA
To serve the growing population of veterans, VHA has
hired more than 7,500 mental health professionals since
2005 and has established specialized rehabilitation cen-
ters for veterans with multiple complex injuries, includ-
ing TBI. Further, VHA offers a broad range of services
and programs tailored specifically to OCO patients with
PTSD and TBI. In this section, CBO presents a brief
overview of typical strategies for diagnosing PTSD and
TBI, along with treatment options that VHA provides for
those conditions.
VHA’s Services for PTSD
As of September 2011, mental health diagnoses were the
second largest diagnostic category among OCO veterans
who had received health care services from VHA, affect-
ing 52 percent of those patients.4 VHA delivers PTSD
care in primary care settings and in specialized programs
of evaluation, treatment, and education. Through its
electronic national clinical reminder system, VHA
endeavors to administer a screening test for various medi-
cal conditions, known as the Iraq and Afghan Post-
Deploy Screen, to all OCO patients.5 That screen
includes the Primary Care PTSD (PC-PTSD) screen,
which consists of four questions. VHA’s policy is to
screen for PTSD every year for the first five years a vet-
eran uses VHA care and once every five years thereafter,
except in cases in which a clinical need for more frequent
screening has been identified.
Veterans who screen positive for PTSD are referred for
additional evaluation. For most patients, further assess-
ment is provided by a mental health professional such as
a psychiatrist, psychologist, or trained clinician. That
assessment typically takes place at a follow-up appoint-
ment, although additional evaluation or a diagnosis may
occur during the visit when the screening occurs. VHA
clinicians make their diagnoses according to the Ameri-
can Psychiatric Association’s Diagnostic and Statistical
Manual of Mental Disorders (DSM), which delineates
the professionally certified criteria for mental disorders in
the United States. Diagnoses are made using a variety of
diagnostic tools, often in combination, such as structured
interviews (the Clinician-Administered PTSD Scale),
semistructured interviews (the Structured Clinical Inter-
view for DSM Disorders), and self-reported evaluations
(the PTSD Checklist).
Although PTSD has a well-validated case definition and
diagnostic criteria, it can nonetheless be difficult to diag-
nose and treat. First, some OCO veterans and service
members do not seek treatment for mental health prob-
lems. Despite widespread outreach programs within the
military and VHA, the stigma associated with mental
health disorders may discourage veterans from scheduling
an appointment for an assessment or from requesting
treatment, and fear of harming one’s military career may
inhibit service members from seeking treatment while
they are on active duty. Second, as with many mental
health disorders, there is no objective measure, such as
a laboratory test result, for confirming a diagnosis of
PTSD. Third, some PTSD symptoms—for example,
irritability, emotional numbing, insomnia, and trouble
concentrating—also occur with other conditions. Fourth,
PTSD can impair judgment, especially if combined with
4. The largest category of diagnoses—diseases of the musculoskeletal
system or connective tissue system—applied to 56 percent of
OCO patients. Veterans may receive diagnoses in more than one
category, so the percentages of patients with different diagnoses
sum to more than 100 percent.
5. The screen for deployment-related health risks includes questions
designed to detect depression, alcohol abuse, and TBI, in addition
to those relating to PTSD. The screen may be given in one of
several venues but commonly occurs during a primary care visit.

associated conditions such as substance abuse, and
thereby make it more difficult for veterans with PTSD to
seek or maintain treatment.
VHA provides treatment for PTSD at VHA hospitals,
outpatient clinics, community-based outpatient clinics
(CBOCs), and Vet Centers.6 In addition, VHA pays for
some care delivered through outside providers. VHA
reports that treatment for PTSD is commonly delivered
in outpatient clinics and CBOCs, either through general
mental health clinics or, less commonly, through special-
ized programs provided by PTSD Clinical Teams, Sub-
stance Use PTSD Teams, and Women’s Stress Disorder
Treatment Teams. VHA guidelines instruct clinicians to
tell patients to expect about six months of treatment, but
for patients with severe cases of PTSD or multiple diag-
noses of mental health disorders, treatment may extend
for one to two years or longer. For many veterans, PTSD
oscillates between remission and relapse. The National
Center for PTSD reports that some veterans may never
be free of symptoms; rather, patients may learn coping
mechanisms that allow them to function in private and
public spheres. One of VHA’s treatment goals is to help
veterans develop those mechanisms.7
Treatment for PTSD is tailored to the patient and may
include a combination of psychotherapy (treatment based
on psychology techniques) and pharmacotherapy (treat-
ment using prescription drugs). In addition, all treatment
programs for PTSD in VHA provide education for fami-
lies and veterans (including coping mechanisms).
VHA offers two forms of evidence-based psychother-
apy—that is, therapy based on a substantive body of
empirical research broadly accepted by the medical com-
munity. Those therapies are cognitive processing therapy
(CPT) and prolonged exposure (PE) therapy. CPT helps
patients change the way the trauma is perceived—for
example, by replacing blame and guilt with less distress-
ing thoughts. In PE therapy, the traumatic events are
narrated repeatedly and combined with exercises to
reduce anxiety in specific situations. The Institute of
Medicine has concluded that exposure therapies, such as
PE therapy, or other therapies that include exposure as
part of treatment, such as CPT, are the only types of psy-
chotherapy that have been found effective for PTSD;
however, the Institute also noted evidence that the effec-
tiveness of exposure therapies for veterans is not as strong
as for civilians.8 Other therapies used by VHA include
group and family therapy.
Clinical research suggests that PTSD patients who
undergo therapy require at least nine treatment sessions.9
VHA reported to CBO that 40 percent of OCO veterans
initiating CPT or PE therapy complete a full course of
therapy. Typically, VHA patients undergoing CPT meet
one on one with a therapist for an hour each week; for
patients undergoing PE therapy, VHA typically schedules
one 90-minute session each week. VHA data from inter-
nal program evaluations indicate that OCO veterans who
completed PE therapy attended an average of 11 sessions,
whereas those who did not complete therapy attended an
average of 5 sessions; results were similar for patients
undergoing CPT. Additional data from a recently pub-
lished study found that 80 percent of OCO veterans who
used VHA’s services and received new PTSD diagnoses
had at least one follow-up visit; nonetheless, fewer than
half completed the recommended treatment sessions
within one year.10 The reasons for not completing a full
course of therapy may include the following: the distance
between home and the location of care, a preference for
receiving mental health care from providers outside
VHA, difficulty scheduling appointments, negative per-
ceptions of mental health care, and impaired judgment as
a result of either the condition itself or associated prob-
lems such as substance abuse.
Pharmacotherapy in VHA consists mainly of the use
of antidepressants, such as selective serotonin reuptake
6. In addition to providing clinical care services, VHA operates
about 300 Vet Centers for veterans and their families at no out-
of-pocket cost. Vet Centers offer readjustment services such as
individual and family counseling, assistance in applying for VHA
benefits, and information on other community and educational
opportunities. Veterans using those services need not be enrolled
for VHA’s health care services, and they retain anonymity for any
counseling they receive.

inhibitors (SSRIs) and serotonin norepinephrine
reuptake inhibitors (SNRIs). If unsuccessful, treatment
may expand to mood stabilizers, anticonvulsants, antipsy-
chotics, or other agents to alleviate symptoms such as
anxiety, intrusive thoughts, flashbacks, and insomnia. In
one study, VHA researchers determined that pharmaco-
therapy was more likely to be prescribed for patients
receiving a diagnosis in a mental health clinic than for
those diagnosed in a general medical or PSTD clinic.11
A small share of OCO patients with PTSD diagnoses
undergoes psychiatric hospitalization—5 percent through
2010. Such hospitalizations include both traditional
inpatient stays and specialized programs involving short
residential stays; those stays involve counseling and treat-
ment with social, vocational, and recreational therapies.
VHA’s Services for TBI
TBI is classified as mild, moderate, or severe on the basis
of its severity at the time of the injury. Because moderate
and severe TBIs are easily identified and require immedi-
ate attention, acute care for combat-related TBIs is
given by DoD, whereas VHA provides rehabilitation
care. Moderate and severe TBIs are clinically different
from mild TBIs, and their treatment typically involves
substantially more health care resources. Veterans who
experienced moderate or severe TBIs may receive inpa-
tient rehabilitative care, outpatient rehabilitative care,
or both, through programs that specialize in treating
complex patients. Along with occupational, cognitive,
physical, and other therapies, VHA also provides
advanced technologies to veterans with ongoing needs
related to sensory impairment, communication deficits,
mobility, and self-care. The course of treatment pre-
scribed and the services provided vary significantly by
patient and are tailored to the severity of the TBI and
ongoing problems.
Veterans with mild TBI are also eligible for VHA’s TBI
rehabilitation programs, but they are usually treated on
an outpatient basis for less intense clinical symptoms and
for a much shorter duration than moderate and severe
TBI patients. In April 2007, VHA directed that all OCO
veterans who use VHA and have not received a prior
diagnosis for TBI be screened for symptomatic TBI—
that is, TBI with currently occurring symptoms such as
headaches, memory difficulties, or sleep problems.
Because moderate and severe cases are readily detected,
the purpose of this screen, in effect, is to identify mild
TBI. Since April 2007, questions designed to detect TBI
have been included in VHA’s Iraq and Afghan Post-
Deploy Screen. For those who screen positive, additional
evaluation takes place with the patient’s agreement; in the
absence of that consent, VHA requires that the patient’s
refusal to undergo further evaluation be documented.
Through 2009, approximately one in five OCO veterans
screened positive for symptomatic TBI. Two-thirds of
those screening positive (or 14 percent of all screened
patients) completed a comprehensive evaluation (some of
those may not have undergone further testing because
symptoms had resolved before the full evaluation was
conducted). Of the 14 percent receiving a comprehensive
evaluation, VHA clinicians diagnosed symptomatic TBI
in one-half of those who screened positive (or 7 percent
of all those initially screened).12
Some VHA medical facilities use individual neurologists,
rehabilitation physicians, or psychiatrists for the follow-
up evaluation, whereas others refer patients to an
interdisciplinary team. Evaluation includes a complete
history of injury, a physical exam, and a neurobehavioral
inventory of TBI symptoms. Other diagnostic tools for
TBI are limited. In some cases, a veteran’s medical records
from DoD are incomplete or unavailable, because DoD’s
and VHA’s medical systems are not fully integrated. Cor-
rect diagnosis is problematic, as none of the symptoms
of TBI are unique to that condition, and there is no
clinically validated definition for TBI with persistent
symptoms months after injury. Thus, many of the diffi-
culties in diagnosing and treating PTSD also apply to
symptomatic TBI: Some veterans may not seek care;

12. David Cifu, National Director of VA’s Physical Medicine and
Rehabilitation Office, “The Veterans Health Administration Poly-
trauma System of Care” (PowerPoint slides transmitted via e-mail,

the prevalence of symptomatic TBI. Headaches, concentration
and memory problems, fatigue, irritability, and sleep disturbance
are common symptoms seen in veterans returning from war, as
well as in individuals with other medical conditions. Whether
symptoms that occur months or years after a TBI can be unequiv-
ocally attributed to mild TBI, as opposed to other conditions, has
been the subject of considerable debate. See Charles Hoge and
others, “Care of War Veterans with Mild Traumatic Brain
Injury—Flawed Perspectives,” New England Journal of Medicine,

CBO
there is no objective diagnostic tool to confirm the
diagnosis; symptoms may coincide with those of other
conditions; and VHA’s diagnostic process often relies
heavily on the veteran’s memory, which may be impaired
as a result of TBI or another medical condition.13
After confirmation of the diagnosis, additional physical
examinations, laboratory tests, and psychosocial evalua-
tions may be performed.14 Because there is no standard
treatment regimen, a team of clinicians typically evaluates
the results and determines a treatment plan, which
accounts for concurrent disorders. According to VHA’s
guidelines, patients with symptoms persisting beyond
four to six weeks of treatment should be reassessed,
assigned to a case manager, and receive treatment for their
remaining symptoms.
VHA considers the management of physical, behavioral,
and cognitive symptoms fundamental to treatment of
mild TBI. The two mainstays of treatment are symptom-
specific treatment (such as managing headache pain, the
most common symptom of TBI) and educating patients
on their expected recovery. VHA states that treatment
through primary care clinics is appropriate for managing
TBI when implemented by an interdisciplinary team of
rehabilitation therapists, pharmacists, and mental health
clinicians. Pharmacotherapy is sometimes used alone or
in conjunction with other therapies to treat musculoskel-
etal pain, anxiety, or psychiatric symptoms. However,
there is currently no clinically validated pharmacotherapy
to improve neurocognitive function after a mild TBI. As
with PTSD, providing education for veterans and fami-
lies about TBI is an important part of treatment. VHA’s
guidelines advise providers to reassure patients and their
families that mild TBI is normally transient and full
recovery without permanent damage is expected. Dura-
tion of treatment for mild TBI at VHA is normally one
to three months, with follow-up four to six weeks later to
confirm recovery, which is defined as the resolution of
symptoms and normal functioning. For some patients,
however, symptoms may persist beyond six months to a
year or longer. Further evaluation for other conditions
may be indicated for persistent symptoms.
Concurrent Diagnoses of PTSD and TBI
TBIs sustained in Iraq or Afghanistan are often the result
of explosions and involve other injuries; moreover, PTSD
has been shown to occur more commonly in veterans
with combat-related concussions (mild TBIs) than in
those with other injuries. The Institute of Medicine’s
Committee on Gulf War and Health found evidence,
albeit limited, suggesting that TBI and PTSD are
associated.15 CBO’s analysis of VHA data found that
three-quarters of OCO patients with a TBI diagnosis
also had a diagnosis of PTSD and that one-fifth of
OCO patients with a PTSD diagnosis also had a
diagnosis of TBI.16
Because PTSD and TBI may generate many of the
same symptoms, a person who has both conditions may
be diagnosed for only one and not the other or, alterna-
tively, diagnosed with both but have only one condition.
Medical consensus is lacking on the accuracy of screening
and diagnosis for both conditions if the person has con-
current PTSD and TBI. Diagnosing only one of the
conditions when both are present can lead to difficulties
with treatments. For example, treatments for either mild
TBI or PTSD alone may not be effective for patients with
both conditions, as cognitive impairment may hinder
adherence to treatment.
Polytrauma
VHA uses the designation “polytrauma” to describe com-
plex, severe injuries to multiple organ systems that often

cians face in diagnosing TBI, see Heather Belanger and others,

result from the same event, such as an explosion. Those
may include brain injury, amputation, hearing and vision
impairments, spinal cord injuries, and psychological
trauma. A small number of patients who have those com-
plex injuries are treated in VHA’s Polytrauma System of
Care, which provides comprehensive, interdisciplinary
rehabilitation and other care for seriously disabled
patients. The Polytrauma System of Care includes five
Polytrauma Rehabilitation Centers for inpatient rehabili-
tation, as well as secondary sites and clinical teams for
postdischarge care.17
Cooperation Between VHA and DoD
Soon after the conflicts in Afghanistan and Iraq began, it
became apparent that some wounded service members
were encountering significant difficulties when making
the transition from DoD’s health care system to VHA’s.
To address those concerns, DoD and VHA have
increased their cooperation and have devoted more
resources to encouraging service members and veterans to
seek care.18
In the summer of 2007, DoD and VHA instituted the
Wounded, Ill, and Injured Senior Oversight Committee
to address problems specific to those service members,
which include the coordination of health care manage-
ment, disability evaluation, and transition of OCO
service members’ health care from DoD to VHA.19 The
committee has several work groups charged with address-
ing particular issues, including one that focuses on the
needs of service members and veterans with PTSD and
TBI.
The Wounded Warrior Act, part of the National Defense
Authorization Act for Fiscal Year 2008 (Public Law 110-
181, sections 1601–1676) required DoD and VHA to
implement many initiatives, including reducing waiting
time for medical care, consolidating their disability evalu-
ation systems, and establishing standards to determine
whether and when wounded service members could
return to active duty. The law also mandated that the
Government Accountability Office (GAO) deliver prog-
ress reports on those initiatives to the Congress. In its July
2009 report, GAO found that although DoD and VHA
had not fully developed or implemented the requirements
of the Wounded Warrior Act, they had made consider-
able progress.20
DoD and VHA have targeted the coordination of health
care management to service members with TBI or with
PTSD and other mental health conditions. In particular,
the agencies are collaborating on myriad issues such as
screening, diagnosing, and treating those conditions, as
well as assisting service members in their transition from
DoD’s health care system to that of VHA. One result of
that collaboration is the TBI screen used by VHA, which
was derived from the screen first used by DoD at certain
military bases. DoD and VHA have formed joint com-
mittees, such as the VHA/DoD Mental Health Working
Group; participate in joint research ventures, such as the
Defense and Veterans Brain Injury Center; and share
clinical practice guidelines, such as Management of
Concussion/Mild Traumatic Brain Injury.21 DoD and
VHA clinicians may collaborate on service members’
transition to VHA’s care; however, the proliferation of
programs and case managers can be confusing for service
members and has led to some duplication of efforts.22
Because the sharing of medical records between DoD and
VHA would greatly facilitate the transition of service
members between the agencies, the Wounded Warrior
Act included provisions designed to achieve such sharing;

tive to provide funding to facilitate greater community outreach,
place PTSD specialists or treatment teams in each VHA Medical
Center, and expand evidence-based care for PTSD.

however, that objective remains a work in progress.
DoD and VHA do have complex sharing agreements and
information-exchange projects to coordinate their inde-
pendent record systems. For example, DoD can transfer
the medical records of service members who have sepa-
rated from DoD and are eligible for VHA care through
the Federal Health Information Exchange. Moreover,
health care clinicians for DoD and VHA can access
records for patients treated by providers in either agency
through the Bidirectional Health Information Exchange.
Yet technical and organizational challenges have made it
difficult to construct a unified electronic medical record.
The Virtual Lifetime Electronic Record (VLER)—a joint
effort of DoD and VHA—overcame a major hurdle in
2010 when DoD and VHA agreed to use a common per-
sonal identifier. Slated for VHA-wide implementation in
2012, the VLER is a single electronic record that would
be used to manage comprehensive administrative and
medical information for service members throughout
their lives, from enlistment to death, regardless of health
care provider.
Current record-sharing goals for VHA and DoD extend
to a broader effort with the private sector, the Nationwide
Health Information Network (NwHIN).23 This group of
federal agencies and private organizations has agreed to
securely share patients’ health information electronically
among providers and health care systems by defining
standards, services, and policies. Pilot projects for
NwHIN are under way; veterans who agree to participate
allow their public- and private-sector health care provid-
ers to share specific health information.
CBO’s Analytical Approach to VHA Data
In this study, CBO presents data on the use of VHA’s
health care services between fiscal years 2004 and 2009
by OCO veterans who received a diagnosis of PTSD or
TBI.24,25 CBO also presents estimates of the costs that
VHA has incurred to treat OCO veterans with PTSD,
TBI, or both during that period and compares them with
the costs of providing care to OCO patients who do not
have PTSD or TBI.26 CBO’s estimates are based on
VHA’s cost data and do not include expenditures by other
federal providers of health care or private insurers, out-of-
pocket costs, forgone earnings, or other losses to society
associated with the two conditions.27
CBO’s primary analysis focused on VHA patients who
had not been treated at specialized polytrauma facilities,
which provide care for veterans who suffer from more
than one complex physical or mental trauma. That analy-
sis examined the use of VHA’s health care services and
cost of providing those services for 496,800 OCO veter-
ans in four mutually exclusive groups:
103,500 patients with PTSD (but not TBI);
8,700 patients with TBI (but not PTSD);
26,600 patients with both PTSD and TBI; and
358,000 patients with neither of those two condi-
tions.28
Patients in the PTSD group did not have TBI, but many
had other conditions; similarly, patients in the TBI group
did not have PTSD, but many had other conditions.
None of the groups includes 500 polytrauma patients,
many with PTSD and TBI, who were analyzed separately.
The data include 99 percent of all OCO veterans seen by
VHA from 2004 to 2009. To protect patients’ confidenti-
ality, VHA did not provide CBO with data on individual
23. NwHIN is led by the Department of Health and Human Services.
For more information, see http://healthit.hhs.gov/portal/server.pt/
community/healthit_hhs_gov__nhin_exchange/1407.
24. VHA did not provide CBO with data from the start of overseas
contingency operations in 2001. However, the number of OCO
veterans entering VHA before 2004 was relatively small: Roughly
10,000 veterans who deployed to Iraq and Afghanistan had sought
VHA’s health care services by the end of 2003.
25. Vet Centers provided PTSD services to 42,000 OCO veterans
through June 2011; among those veterans, 27,000 were also seen
for PTSD at a VHA medical center. The data that CBO analyzed
do not include information on the 15,000 veterans seen only at
Vet Centers.
26. In the information that it provided to CBO, VHA converted its
cost data to fiscal year 2009 dollars on the basis of annual
increases in the average cost of a primary care visit from 2004 to
2009. CBO then indexed those costs to 2011 dollars using the
implicit price deflator for gross domestic product.
27. Initial hospitalizations for the more severe cases of TBI are not
included in VHA’s costs because those individuals were still on
active duty at the time of initial injury and would have been
treated within DoD.
28. TBI describes an injury event, but the term TBI may also refer to
symptoms that persist beyond the acute period. In this study, TBI
patients are OCO veterans who, when examined at VHA facili-
ties, exhibited symptoms attributed to a TBI.

CBO
patients. Because VHA did not identify the date of
patients’ first diagnosis or entry, CBO was not able to
calculate the use or the cost of health care for patients
entering VHA treatment in any given fiscal year.
For the first three groups, CBO presents data on the use
of services and costs of treatment for the first year of care
(treatment year 1) and for up to three additional years
following initial diagnosis.29 Data on patients with no
diagnosis of PTSD or TBI are presented for comparison
purposes following their initial visit for any VHA care.
CBO did not receive detailed clinical data and thus was
not able to construct a comparison group that was similar
in all observed ways to the three groups apart from their
diagnosis of PTSD, TBI, or both. The patients with and
without PTSD or TBI were roughly similar in age, sex,
and military experience, but they differed in certain char-
acteristics, particularly injuries sustained while deployed
in overseas contingency operations. In general, service
members who had PTSD or TBI were more likely to have
received other injuries, so the costs of care for the PTSD
and TBI groups probably would have been higher even
without the costs of care for PTSD and TBI. The poly-
trauma group, which consisted of patients with multiple
complex injuries requiring extended inpatient stays for
rehabilitation at VHA, is examined separately later in the
study; it was a very small group whose average medical
costs were far higher than those of the four other groups.
CBO’s analysis is based on data from VHA’s administra-
tive records from 2004 through 2009. Because some
patients started using VHA’s services partway through the
sample period, not all patients were observed for the full
six years. Indeed, CBO used only the first four years of
data even when six years were available because data for
that longer span existed for only a small minority of vet-
erans. When fewer than four years of data existed, CBO
included all of the years available. Consequently, when
CBO examined patients’ first year of treatment, those
who entered the VHA system in 2008 and 2009 were
included, but when CBO examined later years of treat-
ment, those patients were not included, having entered
the system too late in the sample period.
Not only do patients entering VHA in 2008 and 2009
have fewer years of treatment data available, they are also
different from those who entered in earlier years in two
other ways. First, more veterans entering the VHA system
in those later years had experienced longer deployments
and multiple deployments. Second, starting in 2008,
VHA extended enhanced eligibility from two years to five
years for OCO veterans (see Box 1 on page 2). That
extension enabled veterans with delayed-onset PTSD or
other combat-related conditions for which they had not
previously sought treatment to enter the VHA system
and receive care at no cost. However, CBO does not
believe that those two differences substantially affected
the number or severity of PTSD or TBI cases or, more
generally, the injuries or other medical conditions treated
at VHA in 2008 and 2009.30
While screening and treatment for PTSD were consistent
across the years, VHA’s clinical practices for TBI changed
during the data period (2004 to 2009): The agency initi-
ated comprehensive screening for mild, symptomatic
TBI in 2007. As a consequence, the characteristics of TBI
patients are likely to be different across treatment years.
Patients whom VHA diagnosed with TBI before 2007
were more likely to have had moderate to severe TBI than
those diagnosed in 2007 or after. The study period ended
before the newly identified mild cases could accumulate
four treatment years. Therefore, moderate and severe
cases are more common among TBI patients in treatment
years 3 and 4 than in treatment years 1 and 2. Because
CBO did not have information on TBI severity (mild,
moderate, or severe), it was not possible to separate the
29. To determine the group to which a patient belonged, each OCO
patient’s administrative record was checked for any diagnosis code
of PTSD or TBI, and the patient was assigned to the relevant
group. Any patient with both codes was classified as having both
PTSD and TBI. No patient could be included in more than one
diagnosis group; once classified, patients remained in the same
group for the entire sample period. The sample included all PTSD
and TBI cases among OCO veterans diagnosed at VHA, regard-
less of whether those conditions were sustained while deployed.
The share of veterans who acquired PTSD or TBI unrelated to
deployment (for example, injury from an automobile accident
after returning from Iraq or Afghanistan) is unknown but is prob-
ably a small portion of CBO’s sample.
30. Veterans who became part of CBO’s sample in those later years are
more likely to have remained in the military longer after deploy-
ment than those who entered in the early years of 2004 and 2005.
Any health conditions that veterans who entered VHA in 2008
and 2009 developed during deployment, therefore, were more
likely to have been treated by DoD before those service members
transferred to VHA. The extension of enhanced eligibility in 2008
appears to have had a minimal effect on entry into the VHA sys-
tem. VHA provided CBO with data showing that both before and
after the policy change, most veterans who used VHA services did
so within two years of separation from active duty.

CBO
use of services and costs by severity. The costs of treating
mild TBI, however, are likely to be substantially lower
than the costs of treating moderate and severe TBI. As
a result of the policy change, use and costs in later
treatment years grow for TBI patients and are almost as
high in treatment year 4 as in treatment year 1. Without
the policy change, use and costs for those patients proba-
bly would have been highest during the first year of care
and then declined and stabilized thereafter, as occurred in
the other groups.
VHA provided CBO with aggregate use and cost data for
groups of OCO veterans based on their demographic
characteristics, medical condition, and medical services
used.31 Because data were provided at the group level,
CBO can only present information on averages for those
groups and not on the distribution of use or cost within
groups. (For additional information about the data and
methodology used in this analysis, see Appendix B.)
CBO calculated total and average costs for patients who
accessed VHA’s services at least once, for up to four years
after their PTSD or TBI diagnoses or, in the absence of
those diagnoses, average costs for up to four years after
their entry into the VHA system. Diagnostic tests and
pharmacy use were included and categorized as part of
outpatient costs. As with all analyses based on administra-
tive data, errors and nonstandardized coding may affect
the results presented here.
Occurrence and Prevalence of
PTSD and TBI
In the VHA data provided to CBO regarding 496,800
OCO veterans treated by VHA between 2004 and 2009,
veterans with a diagnosis of PTSD (but not TBI)
accounted for 21 percent (103,500) of the total, and
those with a diagnosis of TBI (but not PTSD) accounted
for 2 percent (8,700). In addition, veterans with diagno-
ses of both PTSD and TBI accounted for about 5 percent
(26,600). Thus, three out of four OCO veterans with a
diagnosis of TBI had a concurrent PTSD diagnosis.32 In
total, approximately 26 percent (130,100) had at least
one diagnosis of PTSD, and 7 percent (35,300) had at
least one diagnosis of TBI.33 More than 70 percent
(358,000) of OCO veterans treated by VHA were not
diagnosed with either PTSD or TBI. Other mental
health conditions besides PTSD are common within the
OCO veteran population. (For a brief description of
other mental health conditions and suicide in that popu-
lation, see Box 2.)
The occurrence of PTSD and TBI among OCO veterans
who use the VHA system—which is measured by the
diagnosis rates just described—does not necessarily reflect
the prevalence of those conditions in the entire OCO
population. If service members who have separated from
the military are more likely to have service-connected
health problems than those who have remained on active
duty, then the rate of diagnosis among VHA patients
will be higher than the proportion of the entire OCO
population that has those problems. If, however, suffi-
cient numbers of veterans with PTSD or TBI were either
being treated for the condition elsewhere or not being
treated at all, the rate in the overall OCO population
could be greater than the rate diagnosed among VHA
patients. For example, some veterans have employment-
based health insurance; others seek care from other
sources that are not connected to their military service,
perhaps because providers are located more conveniently
or are perceived to be more private; and still other veter-

31. VHA computes costs on the basis of its internal reporting systems.
Costs for treating PTSD and TBI in the civilian population and
veterans treated at VHA are unlikely to be comparable because of
differences in cost allocation methodologies, the populations
treated, and the mechanisms of injury. Also, while VHA data mea-
sure the costs of care, private-sector estimates are often based on
insurance reimbursements to private providers, which are not
identical to costs.
32. VHA researchers examining OCO veterans treated at VHA have
reported rates of concurrent diagnoses that are similar to CBO’s;
however, some researchers drawing from broader samples of OCO
service members and veterans find lower rates of concurrent TBI
and PTSD. In the three studies with the largest sample sizes,
between 33 percent and 39 percent of OCO veterans with mild
TBI also screened positive for PTSD. See Kathleen F. Carlson
and others, “Prevalence, Assessment, and Treatment of Mild
Traumatic Brain Injury and Posttraumatic Stress Disorder: A
Systematic Review of the Evidence,” Journal of Head Trauma
Rehabilitation, vol. 26, no. 2 (March–April 2011), pp. 103–115.
33. If the threshold is raised to include only veterans who had two or
more visits coded with a diagnosis of PTSD or TBI, the rates that
CBO estimates drop to 20 percent and 3 percent, respectively.
(Some researchers consider a two-visit measure a more definitive
indicator of a condition, although that more-stringent threshold
will miss those veterans who have PTSD or TBI but leave the
VHA system after the initial diagnosis.)

CBO
been measured well, but it is likely to reduce the number
of people who admit to problems associated with PTSD
and then screen positive. For those reasons, the preva-
lence—that is, the estimate of the proportion of cases in a
population, whether or not the individual has received a
clinical diagnosis from a medical professional—of PTSD
and TBI in the OCO population probably differs from
the percentage of patients in the VHA system diagnosed
with those conditions.
Many researchers have estimated PTSD and TBI preva-
lence among different groups of service members
and veterans who deployed to operations in Iraq and
Afghanistan, but there is no consensus as to the preva-
lence rate among the entire OCO population.34
Researchers generally have reported prevalence rates rang-
ing between 5 percent and 25 percent for PTSD among
different groups of service members who deployed to
overseas contingency operations, with generally higher
rates in studies of infantry brigades or combat teams.
Researchers have found that the proportion of service
members who experienced a TBI, including those who
no longer had symptoms, ranged from 15 percent to
23 percent, and that the proportion of service members
who had symptomatic TBI after returning from deploy-
ment ranged from 4 percent to 9 percent. Thus, the
percentage of OCO veterans whom VHA clinicians
have diagnosed with PTSD (26 percent) is at the top
of the range of prevalence reported in published studies,
whereas the percentage they have diagnosed with
symptomatic TBI (7 percent) is in the middle of the
reported range. The estimates of symptomatic TBI
remain uncertain because there are no clinically validated
diagnostic criteria for that condition, and connecting
self-reported persistent symptoms to the initial injury is
problematic. Published estimates of PTSD and TBI dur-
ing deployment vary widely because the assessment tools
used to identify the conditions, the criteria used to iden-
tify cases, and the subgroup of service members sampled
differ among studies. (For a detailed discussion of those
issues, see Appendix C.)
The gold standard for determining prevalence would be
to evaluate each person in a representative sample of the
OCO population using validated clinical interviews;
achieving that ideal, however, would be expensive and
difficult. Instead, some researchers use administrative
data on diagnoses to measure the number of cases of
PTSD and TBI; others use clinical screening tools to
assess cases. Administrative data on diagnoses understate
prevalence in a population because not everyone seeks
care. Some researchers who use screening tools to identify
PTSD and TBI apply low thresholds for assessing those
conditions. In so doing, however, they may also generate
many false positives and overestimate the number of
cases. Conversely, researchers employing more restrictive
thresholds could underestimate cases.
In addition, most studies to date, including some that
attempt to be population-based, have oversampled cer-
tain groups; applying rates from nonrandom samples
without the proper weighting is unlikely to yield an accu-
rate measurement of prevalence. On the one hand, esti-
mates based on combat units, which experience higher
rates of physical and psychological trauma than other
types of military units, may lead to prevalence estimates
that are too high to apply to the general population of
service personnel in a combat region, which includes sup-
port units. On the other hand, samples based on return-
ing, uninjured troops may lead to estimated prevalence
rates that are too low.
Another shortcoming with published studies, which
applies also to diagnosis rates within VHA, is that service
members and veterans may not accurately report their
symptoms. The stigma associated with screening positive
for PTSD, the perceived inconvenience of undergoing
additional evaluation, or a lack of confidence in treat-
ment effectiveness may lead to an underreporting of
symptoms of mental health problems or TBI and thus
an underestimate of prevalence.
Finally, using estimates of TBIs that occur during deploy-
ment is problematic because even a confirmed clinical
diagnosis when or shortly after an injury is sustained does
not reveal the frequency of persistent postconcussive
symptoms. DoD reports that, although a small minority
of service members has ongoing symptoms, most cases of
TBI are mild, often resolving within weeks and almost
always improving within three months.
34. Those studies included papers that reported frequencies of possi-
ble cases of PTSD or TBI regardless of whether the objective of
the study was to estimate the prevalence in the broader OCO
population.

Use of VHA’s Services
Through September 2011, VHA reported that the num-
ber of OCO veterans who had used VHA at least once
totaled nearly 740,000, or 53 percent of OCO veterans.
The OCO population using VHA’s services tends to be
male (88 percent), is young (46 percent are younger
than 32), consists predominantly of former soldiers in
the Army (61 percent), and is slightly more likely to be
veterans of active-duty units (56 percent) than reserve
components.
Future spending on OCO patients will change according
to the mix of conditions diagnosed and the number of
Box 2.
Suicide and Mental Illness Among OCO Veterans
Just over half of veterans of overseas contingency
operations (OCO) treated by the Veterans Health
Administration (VHA) have a diagnosis of a mental
illness. Mental health problems can affect all aspects
of life. Suicide among service members and veterans,
an infrequent but devastating outcome of mental ill-
ness, is of particular concern to policymakers and
others.
Suicide
In 2009, the suicide rate for military members serv-
ing on active duty was 18.3 per 100,000, the highest
since 1980. The following year, that rate dropped to
17.0. In the general population, by comparison, the
suicide rate in 2007 was 20.8 among males ages 20 to
24 and 20.7 among males ages 25 to 34.1 From 2003
to 2010, the Department of Defense (DoD) con-
firmed nearly 2,000 suicides among active-duty ser-
vice members, 300 of which occurred during deploy-
ment. Roughly 50 percent of suicides in 2010
occurred among military members who had deployed
to overseas contingency operations. Suicide rates were
higher in the Army and Marine Corps than in other
branches of the military.
Suicides among service members who deployed to
overseas contingency operations also occur after they
leave military service. Studies of Vietnam veterans
reveal that deployment to a war zone is associated
with suicide in the years immediately following
deployment.2 However, information on suicides
among veterans is less complete than it is for active-
duty personnel, and no nationwide surveillance
system exists for tracking the incidence of suicides in
that population.
The Centers for Disease Control and Prevention
(CDC) compiles national statistics on suicide,
but veteran status and the cause of death are not
always reported correctly on death certificates or
summarized accurately by local health officials.
CDC estimates that about 35,000 suicides occurred
in the U.S. population in 2007. A separate system,
the CDC’s National Violent Death Reporting
System—which maintains more comprehensive data
on violent deaths but operates in only a limited
number of states—estimates that veterans accounted
for 20 percent of the suicides in those states in 2005.
The CDC and Department of Veterans Affairs have
ongoing initiatives to tabulate all suicides among
veterans.
Statistics from VHA’s suicide-prevention coordina-
tors indicate that in fiscal year 2009 there were nearly
11,000 suicide attempts among veterans receiving
care from the agency; 6.2 percent were documented
as fatal. Among VHA’s patients in 2007, the rate of
suicide was 35 per 100,000, a rate higher than that
found in the general population. However, that rate is
not adjusted for the demographics of VHA’s user
population. Veterans who use VHA, moreover, may
do so because they have more medical conditions,
including mental health conditions, than other veter-
ans or members of the general population.
1. Historically, rates of death for all causes have been lower
among service members than in the general population.

patients treated.35 CBO’s estimates of diagnosis rates are
useful in projecting VHA’s future costs, but the usefulness
depends on the extent to which the prevalence of those
conditions and veterans’ likelihood to seek treatment at
VHA remain the same. If outreach services motivate
more veterans to seek care, for example, the rate at which
veterans use VHA’s services would tend to increase over
time. Combat exposure should decline with OCO troop
Box 2. Continued
Suicide and Mental Illness Among OCO Veterans
As part of VHA’s expansion of mental health services,
the agency’s suicide-prevention program is wide-
ranging.3 Initiatives include screening OCO veterans
for selected mental health conditions; establishing
suicide-prevention programs in each VHA hospital
and large community-based outpatient clinic; operat-
ing a 24-hour suicide-prevention hotline staffed by
VHA mental health professionals; and developing a
system for flagging the records of patients at high risk
of suicide.
Mental Illness
Among OCO veterans using VHA’s services from
October 2001 through June 2011, 21 percent were
diagnosed with a depressive disorder. Other mental
health conditions commonly diagnosed among
OCO veterans are anxiety and drug or alcohol abuse.
OCO patients with mental health conditions often
have multiple conditions of this type.
Treatment for mental illness is provided at local
facilities in broad consultation with VHA’s Office
of Mental Health Services, which has been imple-
menting recommendations from its comprehensive
five-year Mental Health Strategic Plan. That plan,
which focused on gaps in mental health care for vet-
erans, had several goals, which included addressing
the mental health needs of OCO veterans and pre-
venting suicide. One of the steps being taken to
achieve those goals is to better integrate mental
health treatment and primary care. For fiscal year
2010, VHA obligated $5.2 billion for mental health
programs—more than a tenth of its total spending
for medical care; obligations are slated to exceed
$6 billion by 2012.4 Available services consist of out-
patient specialty programs, inpatient psychiatric care,
residential and vocational rehabilitation, substance
use disorder care, and various local initiatives.
VHA provided CBO with information on the use of
VHA’s health care services and the costs of providing
those services for 73,000 OCO veterans who had a
mental health diagnosis other than PTSD (and no
diagnosis of TBI). When compared with OCO
veterans with no mental health diagnosis, patients
with mental health disorders other than PTSD made
greater use of VHA’s health services in treatment
year 1 as measured by inpatient hospital days (0.6 per
year compared with 0.08 per year for veterans with
no mental health diagnosis), annual outpatient visits
(16 versus 8), and prescriptions filled (9 versus 3).
When compared to OCO patients with PTSD,
patients with other mental health conditions spent
the same share (one-quarter) of their hospital days in
psychiatric care but used less health care overall. For
the first year of treatment, VHA spent $350 million
on patients with other mental health diagnoses. The
average cost of care during the first year of treatment
($4,300) was more than double that for OCO
patients with no mental health diagnoses ($2,000)
but only half the average cost of treating OCO
patients with PTSD.

on the part of the government to pay for goods and services
ordered or received. Such payments may be made immedi-
ately or in the future. Obligations during any year may
exceed appropriations provided during that year because
an agency may obligate funds that were provided in an
earlier year.

levels, however, so fewer service members are likely to
develop PTSD or TBI in the future. In addition, an
increasing share of veterans who do seek care from VHA
in the future will have deployed several years earlier and
are more likely to have sought care through DoD or to
have had their symptoms resolve than was the case for
veterans who sought care from VHA before 2010. For
those reasons, future veterans enrolling in VHA’s health
care system are less likely to seek treatment for PTSD or
TBI.
CBO measured the use of services by the number of
patients who used VHA’s services after a diagnosis of
PTSD or TBI and by the frequency of their use after
those diagnoses. CBO measured VHA’s services in three
categories: inpatient care (in days), outpatient care (in
number of clinic visits), and pharmacy services (in 30-day
equivalent prescriptions filled). CBO calculated the aver-
age use by service type in each treatment year for veterans
who ever used VHA’s services.
Patients who had PTSD, TBI, or both conditions used
the VHA system much more in any given year and were
more likely to use VHA’s services than were patients with
neither diagnosis. (This section of the analysis focuses on
all health care services provided to patients in each group,
regardless of whether a particular service was related to a
PTSD or TBI diagnosis.) CBO found the highest average
use of all health care services among patients who were
treated for both PTSD and TBI. The use of services by
TBI patients was roughly comparable to that of PTSD
patients in the first two treatment years, but TBI patients
(probably those with moderate to severe TBI) had mark-
edly higher inpatient and outpatient use in treatment
years 3 and 4. With the implementation of comprehen-
sive screening for mild TBI in 2007, patients with
moderate to severe TBI accounted for a larger share of
cases in treatment years 3 and 4. Veterans with neither
condition used VHA the least, with little change over the
four treatment years. Use of services for most groups was
highest in the first year of care.
Number of Patients Using VHA’s Services
The share of veterans who continued to access care at
VHA declined in the years following their initial use of its
services; however, the rate of decline differed among the
groups CBO analyzed. The largest decrease occurred in
the group that had no diagnosis of either PTSD or TBI;
less than half (42 percent) of those veterans continued to
use VHA four years after initial use (see Figure 1).

Notes: For treatment years 2 through 4, the share of patients
treated by VHA represents the number of patients using
VHA’s services divided by the number of potential
patients—those who were diagnosed with the condition
in treatment year 1 and who remain in the sample
(see Table D-1).
Data cover fiscal years 2004 to 2009 for up to the first four
years of treatment. Data exclude about 500 patients, many
with PTSD and TBI, who entered VHA at Polytrauma
Rehabilitation Centers.

contingency operations; PTSD = post-traumatic stress
disorder; TBI = traumatic brain injury.
a. Patients in the PTSD group did not have TBI, but many had

b. Patients in the TBI group did not have PTSD, but many had other

By contrast, at least two-thirds of veterans in the other
three groups continued to use VHA for some of their
health care four years after initial diagnosis. Those
patients might have had more clinically complicated con-
ditions that took longer to resolve. In addition, those
patients’ more intensive initial use of services might have
predisposed them to continue pursuing care. Because of
their conditions, moreover, some patients could also have
had limited opportunities for employment, a common
source of alternative health care options.

OCO veterans using any health care services at VHA at

into the system, were included in the calculations. Gener-
ally, OCO patients used VHA’s services most intensively
in the first year of treatment, after which use declined and
stabilized (see Figure 2). The most notable exception was
for patients with TBI (including those with both PTSD
and TBI); their average use in each service category
increased in treatment years 3 and 4. Patients who had
neither a diagnosis of PTSD nor a diagnosis of TBI aver-
aged many fewer inpatient days, outpatient visits, and
pharmacy prescriptions than members of the other
groups.36

36. Veterans enrolled in the VHA system usually have other sources of
health care available to them and use VHA’s services for a minority
of their care. Because CBO has no data on OCO veterans’ use of
health care outside of VHA, it cannot determine differences in the
total health care services used by the different groups. Conse-
quently, OCO veterans with no diagnosis of PTSD or TBI may
receive a higher or lower portion of their care from VHA than the
other groups.

day in all of the years following their first visit.37 The
largest single category of inpatient care for this group in
treatment year 1 was medical or surgical care (accounting
for 41 percent). By contrast, the PTSD group averaged
about two inpatient days in treatment year 1: 44 percent
of those days were for residential rehabilitation (often
treatment for mental health and substance abuse that
focuses on community reintegration), and 27 percent
were for psychiatric care. The TBI group averaged about
three inpatient days in treatment year 1: 33 percent of
those days were for rehabilitation medicine (treatment for
physical impairments and disability), and 27 percent were
for medical or surgical care. That distribution changed
dramatically in the later years. The small number of
TBI patients receiving VHA care in treatment year 4
(400 patients) were resource intensive: Inpatient hospital
days for TBI patients doubled from about three in
treatment year 1 to about six in treatment year 4. By
treatment year 4, nursing home care, which was concen-
trated among fewer than 10 percent of TBI patients
seeking care in that year, accounted for 82 percent of
that group’s inpatient days. The final group—those with
both PTSD and TBI diagnoses—averaged nearly four
inpatient days in year 1. Their inpatient use was most
similar to that of the PTSD group, with 39 percent of
inpatient days for residential rehabilitation and
21 percent for psychiatric care.
Outpatient Care. The PTSD group’s use of outpatient
care in treatment year 1 was more than three times as
high (29 visits) as that of OCO veterans with neither
PTSD nor TBI but fell by about half (to 14 visits) in the
following year and then leveled off.38 Although the TBI
group had approximately the same number of outpatient
clinic visits as the PTSD group in treatment years 1 and
2, the average number of visits for the TBI group rose
again in treatment years 3 and 4. By treatment year 4, the
average number of visits for the TBI group (24 visits)
was close to the number in the initial year of treatment
(28 visits). Again, that pattern was most likely caused by
the change in screening for TBI that led to more patients
with mild TBI appearing in these data in earlier treat-
ment years than later ones. Average use of outpatient
care by the group with both PTSD and TBI diagnoses
decreased sharply after treatment year 1 (from 44 visits
to 27 visits in treatment year 2) and then rose a little
thereafter.
In the first treatment year, one-quarter of the PTSD
group’s outpatient visits took place in mental health clin-
ics, and an additional 8 percent of visits were in specialty
PTSD clinics. For the group with TBI, 30 percent of
outpatient care was provided in the aggregated, non-
specific category of “other clinics” (which included
rehabilitation clinics), and 28 percent was provided in
diagnostic testing venues; less than 1 percent of their out-
patient care was provided in TBI clinics. For the group
with both PTSD and TBI, 22 percent of outpatient visits
in treatment year 1 occurred in mental health clinics.
Data provided to CBO for this study did not include suf-
ficient information on individual clinical encounters to
report the initiation or completion of a course of therapy.
Pharmacy Services. The group with neither a PTSD nor
TBI diagnosis averaged four prescriptions annually in all
treatment years.39 The other groups had considerably
more pharmacy services in the first year, from four to
seven times as many as the group with no PTSD or TBI
diagnosis. Although pharmacy services for the other three
groups—those diagnosed with PTSD, TBI, or both—
decreased between treatment years 1 and 2, that decline
was reversed in later years. Indeed, the group of patients
with both PTSD and TBI not only had more pharmacy
services, on average, in treatment year 4 than in treatment
year 1 but also had the highest average number of pre-
scriptions (30 in treatment year 4).
Costs of VHA’s Services
Costs generally followed the same patterns as use of ser-
vices. Thus, the highest average costs were for patients
treated for both TBI and PTSD. Average costs for all
groups of OCO patients dropped in the second year of
37. Inpatient care includes medical or surgical care, rehabilitation
medicine, residential rehabilitation, inpatient PTSD care,
inpatient psychiatric care, PTSD residential rehabilitation,
and nursing home care. Because only one or two categories of
inpatient care generally accounted for a substantial share of treat-
ment, only the largest categories are reported here.
38. Outpatient care includes care provided in various types of clinics:
primary care, medical/surgical care, mental health, PTSD, TBI,
polytrauma, and a more general type denoted as “other.” Diagnos-
tic tests are also included in outpatient care. Because only one or
two categories of outpatient care typically accounted for a sub-
stantial share of treatment, only the largest categories are reported
here.
39. The number of prescriptions filled includes the dispensing of
pharmaceuticals and over-the-counter drugs (as measured in
30-day equivalents), as well as related supplies.

CBO
treatment and, for most groups, stabilized or declined
thereafter. A notable exception was the group of patients
treated for TBI; the average costs for those patients grew
substantially in treatment years 3 and 4. That apparent
anomaly most likely reflects the changing composition of
the TBI group during the four-year treatment period.
Because the data included veterans using VHA both
before and after comprehensive TBI screening was imple-
mented, patients with mild TBI probably accounted for a
larger share of cases during the first two treatment years,
and patients with moderate or severe TBI represented a
greater share of cases during the latter two treatment
years. Because VHA did not provide data that would
enable CBO to separate mild cases of TBI from moderate
or severe cases, CBO’s ability to examine this issue further
is limited.
CBO used two different approaches to analyze VHA’s
costs of treating veterans with PTSD, TBI, or both. The
first method captures the total costs to VHA of treating
those patients but overstates costs related solely to PTSD
or TBI. The second method attempts to attribute costs
for services directly to a diagnosis of PTSD or TBI, which
yields costs that are lower than those estimated using the
first method. However, the PTSD- and TBI-specific costs
can be considered only rough approximations.
In the first approach, CBO calculated the total cost of
all health care provided to OCO patients diagnosed
with PTSD and TBI, regardless of whether that care was
directly related to those conditions. If patients were
treated for a back injury or hearing loss, for example,
those treatment costs were included in CBO’s estimates.
All costs were included because determining which care
is related to a specific condition requires subjective
decisions. Furthermore, patients with PTSD or TBI
frequently develop other conditions that may be caused
or exacerbated by the presence of PTSD or TBI and thus
may be considered additional, indirect costs of PTSD
and TBI.
The second approach that CBO used to compute costs
was to examine only PTSD- and TBI- specific care using
the diagnostic codes identified by VHA’s clinicians.
Determining the cost of treating a particular condition
(rather than the cost of treating a patient with the condi-
tion) requires subjective decisions that attribute a medical
encounter and a specific portion of the cost of that
encounter to a particular condition. Computing PTSD-
and TBI-specific costs, therefore, provides a rough esti-
mate of how much VHA spends on treating those partic-
ular conditions. (See Appendix B for a description of
CBO’s methodology.)
Costs of All Health Care
In calculating total costs of all health care for patients
with a particular diagnosis, CBO examined up to four
years of data. CBO included all patients in the average
cost calculations, whether those patients accessed VHA
once or many times in the four years. (For an alternative
method of examining average costs, see Appendix D.)
Because the data are through 2009, patients that enrolled
in 2007, 2008, and 2009 were not able to accumulate
four years of treatment (see Appendix B).
Total Costs. During fiscal years 2004 through 2009,
VHA spent $3.7 billion for the first four years of treat-
ment on the OCO patients analyzed by CBO.40 CBO
estimates that VHA spent 60 percent of that sum
($2.2 billion) on patients with PTSD, TBI, or both.
The group with neither a PTSD nor a TBI diagnosis—
the largest group, with more than 350,000 patients—had
the highest total costs: $860 million in treatment year 1
and about $1.5 billion in total costs from 2004 through
2009 (see Table 1). Total spending in those years for the
PTSD patients was almost as high ($1.4 billion),
although the PTSD group had many fewer patients.
The share of total costs devoted to inpatient care varied
by treatment group but was fairly stable over the first four
years of treatment for all groups except TBI patients. For
most groups, the share of total costs devoted to inpatient
care was less than 25 percent. For TBI patients, however,
the portion of total costs assigned to inpatient care was
40 percent in treatment year 1 and 50 percent in treat-
ment year 4. A small percentage of TBI patients were
responsible for those costs: Fewer than 10 percent of TBI
patients in treatment year 4 used nursing home care, but
at an average cost of approximately $147,000 per nursing
home patient.
40. See Appendix B for a description of CBO’s methodology. VHA
has reported the number of OCO patients and their associated
costs in the various editions of the agency’s annual budget docu-
mentation. VHA treated 508,000 OCO veterans from 2002
through 2009. The data that VHA supplied to CBO encompassed
98 percent of that population and, because some overhead costs
were not included, about 92 percent of the total costs.

Total Costs for VHA’s Health Care Provided to OCO Patients

Notes: Data cover fiscal years 2004 to 2009 for up to the first four years of treatment. Data exclude about 500 patients, many with PTSD and
TBI, who entered VHA at Polytrauma Rehabilitation Centers.
VHA converted costs provided to CBO to fiscal year 2009 dollars on the basis of annual increases in the average cost of a primary care
visit from 2004 to 2009. CBO then indexed those costs to 2011 dollars using the implicit price deflator for gross domestic product.
VHA = Veterans Health Administration; OCO = overseas contingency operations; PTSD = post-traumatic stress disorder;
TBI = traumatic brain injury.
a. Patients in the PTSD group did not have TBI, but many had other conditions.
b. Patients in the TBI group did not have PTSD, but many had other conditions.
Average Costs. In treatment year 1, the average costs per
patient diagnosed with PTSD ($8,300), TBI ($11,700),
or both ($13,800) were much higher than the average
costs for those with neither PTSD nor TBI ($2,400) (see
Table 2 and Figure 3 on page 20).41 Although patients
with PTSD, TBI, or both had higher average costs, those
costs may not be solely attributable to those two condi-
tions. If patients with PTSD or TBI have worse health
overall (they may be more likely to have combat injuries,
for example) than patients without those conditions,
their costs will be higher. The group with both PTSD
and TBI included patients with persistent symptoms
from multiple conditions, which helps explain why their
use of medical services and the costs of those services were
greater than those for patients with PTSD or TBI alone.
For all groups, the average cost of all health care was high-
est in treatment year 1 (see Figure 3). For three of the
four groups, costs largely stabilized or continued to drop
in the third and fourth treatment years. TBI patients were
different. After dropping below the treatment year 1 level
in years 2 and 3, costs rebounded to $11,100 in treat-
ment year 4. That pattern can be attributed to the com-
position of the TBI sample in later treatment years. As
discussed earlier, the change in TBI screening imple-
mented in 2007 means that the sample of patients ana-
lyzed here had a larger share with moderate or severe TBI
in later treatment years.42 Thus, this result does not imply
that new TBI patients will tend to require higher expen-
ditures for treatment in later years.

eras will be an estimated $9,100 in 2011.
42. In the data provided to CBO, TBI patients who used VHA’s ser-
vices for four years were diagnosed before 2007, when VHA began
comprehensive screening of OCO veterans for mild TBI. Conse-
quently, the portion of the sample drawn before 2007 was much
smaller and probably included relatively more cases of moderate
or severe TBI than later cohorts, making costs for patients with
four treatment years unreliable in predicting future spending.

Notes: Data cover fiscal years 2004 to 2009 for up to the first four years of treatment. Data exclude about 500 patients, many with PTSD and
TBI, who entered VHA at Polytrauma Rehabilitation Centers.
Average annual costs are based on the number of OCO patients who were ever seen at VHA, regardless of whether they were treated
in a given year.
VHA converted costs provided to CBO to fiscal year 2009 dollars on the basis of annual increases in the average cost of a primary care

tabulations of the costs of care that had an accompanying
diagnosis code of PTSD, TBI, or both. CBO reports two
types of costs for patients in the years after diagnosis: total
costs and average costs for PTSD- or TBI-specific care.
The costs calculated using this method are lower than
those presented earlier because they represent only a por-
tion of health care costs for patients, not all costs.
Costs in this section should be considered a rough
approximation of the costs of treating PTSD or TBI; they
may be either too high or too low. When multiple diag-
noses were made during an inpatient stay or outpatient
visit that also included a PTSD or TBI diagnosis, VHA
attributed all costs for that visit to PTSD or TBI. In
addition, CBO attributed all costs for prescriptions and
diagnostic tests to either PTSD or TBI for patients with
those diagnoses (although VHA’s clinical information
systems do not associate diagnosis codes with those ser-
vices).43 That approach may overstate the costs to treat
those conditions. Conversely, patients with PTSD and
TBI often have other medical problems that may be
related to their PTSD or TBI and that pose indirect costs
not included; in such instances, the estimates may be too
low. In addition, oversights on the part of care providers
or medical coders may have resulted in missing PTSD or
TBI diagnosis codes, which also could produce estimates
that are too low.
Total Costs. While PTSD and TBI accounted for a sizable
part of total health care costs, OCO veterans with PTSD
or TBI also received a considerable amount of care for
other conditions, even in the first year of treatment.
VHA spent $1.1 billion for PTSD- and TBI-specific care

Average annual costs are based on the number of OCO

treatment, with more than half of that amount spent
on patients in their first year (see Table 1 on page 18).
For the PTSD group, PTSD-specific care averaged almost
half (46 percent) of total health care costs over four years.
The share was somewhat less (38 percent) for TBI-
specific care for the TBI group. More than half
(57 percent) of the care provided to the group with both
PTSD and TBI was directly related to those specific
diagnoses.
Average Costs. CBO’s estimates of average annual costs
for treating PTSD or TBI or both in patients with those
diagnoses can be regarded only as rough estimates
because of the broad classification of treatments attribut-
able to PTSD or TBI. Following the initial year of treat-
ment for patients with PTSD, which cost $4,100 per
patient for PTSD-specific care, those costs fell by about
half (see Table 2). Average costs of treating veterans with
both PTSD- and TBI-specific care in year 1 ($8,000 per
patient) were almost double those for veterans with
PTSD alone, and $3,000 higher than the average costs of
treating patients with TBI alone. Between treatment year
1 and treatment year 4, the average costs of care for
PTSD and combined PTSD and TBI declined by 54 per-
cent and 29 percent, respectively, but the average costs of
TBI care decreased by only 12 percent during that
period. As noted above, the pattern of costs for veterans
with TBI is distorted by the change in screening during
the sample period.
Other Studies of the Costs of Treating PTSD and TBI
CBO reviewed other studies on the costs of treating
people with PTSD and TBI. CBO focused on studies
examining those conditions in the OCO population, in
part because costs experienced by the civilian population
are unlikely to be comparable to those for the military
population.44 While studies of the costs to treat OCO
veterans have been limited, more research is becoming
available. CBO reviewed two studies of VHA costs, nei-
ther of which attempted to examine the costs of care
related specifically to PTSD or TBI.

44. Reliable, up-to-date estimates of the total costs of PTSD and
TBI are not available for the general population. In addition,
cost estimates for civilians would not be comparable to those for
the military partly because the mechanism of injury is different.
Among OCO veterans, most TBIs are the result of explosions;
military PTSD is typically related to combat.

CBO
One study compared the costs of treating OCO veterans
with PTSD or TBI with the costs of treating OCO
veterans without those conditions.45 In fiscal year 2008,
the average cost for patients with PTSD alone was
between $6,000 and $8,000 (expressed in 2011 dollars),
and the average cost for patients with TBI totaled about
$5,000. (TBI cases in that study were identified through
VHA’s screening and therefore were more likely to have
been mild and less expensive to treat.) The corresponding
cost for patients with both PTSD and TBI was $10,300.
For veterans with neither condition, the average cost was
$2,500, very similar to CBO’s estimate for treatment year
1. Compared with CBO’s estimates, most costs reported
in the study for fiscal year 2008 are lower, but CBO’s data
contained a different mix of cases that included more
severe ones.
A second study examined the average costs in fiscal year
2009 for VHA to treat OCO patients who had used any
outpatient services in that year. The cost estimates, there-
fore, were for patients who first sought care in 2009, as
well as those who had been treated for several years. The
authors found that the median annual cost per patient
with PTSD was $2,800 (expressed in 2011 dollars); the
mean was $5,300. For patients with TBI, the median cost
was $3,400, and the mean was $7,300. For veterans with
both PTSD and TBI, the median cost was $7,300, and
the mean was $12,300.46 Those average values for fiscal
year 2009 are all lower than CBO’s estimates of all health
care costs for such patients for the first treatment year.
Another study, by the RAND Corporation, examined
costs of treating service members who deployed to over-
seas contingency operations, but its focus on societal costs
makes it dissimilar to CBO’s analysis of VHA’s costs.47
Polytrauma Patients
Polytrauma patients at VHA are those with multiple
severe injuries. Patients categorized as polytrauma for
purposes of this analysis first enrolled in the VHA system
as inpatients at one of the Polytrauma Rehabilitation
Centers; about 500 OCO veterans were identified as
polytrauma patients. Some patients with multiple trau-
mas were included in other groups in CBO’s analysis,
however, because their first encounters with VHA were
not at a Polytrauma Rehabilitation Center, but rather at
some other facility.
After initial entry into the polytrauma system, those
patients continued to access VHA’s health care system. In
any given treatment year, at least 95 percent used VHA
and had some PTSD- and TBI-specific care. Like
patients in the other groups, polytrauma patients used
significantly more resources in treatment year 1 than in
later years (see Table 3). The average hospital stay in
treatment year 1 was close to two months, with 73 per-
cent of that care delivered in rehabilitation medicine.
In subsequent years, the average annual length of an
inpatient stay declined dramatically. Outpatient clinic
visits for polytrauma patients were close to half the initial

47. In RAND’s Invisible Wounds of War, researchers estimated the
2005 societal costs, including the costs from unemployment and
suicide, of treating service members who deployed to overseas
contingency operations. The researchers found that the costs of
PTSD ranged from $5,900 to $10,300 for two years. Using Medi-
care reimbursement rates and other data, the researchers reported
that the societal costs of TBI for one year ranged from $26,000 to
$31,000 for mild cases and from $252,000 to $383,000 for mod-
erate and severe cases. Because the data undercounted the number
of mild TBIs and overcounted the number of hospitalizations
attributable to those mild cases, the reported costs for mild TBI
are likely to be substantially overstated. RAND’s estimates of
societal costs should not be compared with CBO’s numbers,
which focus only on VHA’s costs. (Unlike RAND’s estimates,
CBO’s estimates of the costs of treating TBI exclude the initial
hospitalizations of the more severe cases because those individuals
were still on active duty at the time of initial injury and hospital-
ization and therefore would have been treated within DoD.)

analyzed in this study, increased thereafter.
The pattern of use was reflected in the costs of treatment.
The average cost of all health care per polytrauma patient
in treatment year 1 was $136,000, or nearly 10 times the
average cost for the group with both PTSD and TBI.
Average annual health care costs dropped to about
30 percent of their first-year amount in treatment year 2
and to about 20 percent of that amount by year 4.
PTSD- and TBI-specific care accounted for 60 percent

patients during the 2004–2009 period, a percentage
similar to that for the group with both PTSD and TBI.48
In total, health care costs for the roughly 500 polytrauma
patients treated between 2004 and 2009 exceeded
$91 million.

48. Because polytrauma patients have many other medical conditions,
it is difficult to attribute a portion of their total costs of care
specifically to PTSD and TBI. The relatively high average costs
credited to PTSD- and TBI-specific care is probably an artifact of
how such costs are allocated. See Appendix B.

Appendix A:
Background on PTSD and TBI
Post-traumatic stress disorder (PTSD) is an anxiety
disorder induced by exposure to a traumatic event.
Although the psychological effects of combat have long
been recognized (in previous wars, the symptoms now
associated with PTSD were known as “shell shock” or
“battle fatigue”), the American Psychiatric Association
did not codify PTSD as a separate mental disorder until
1980. Traumatic brain injuries (TBIs) are defined as a
blow, jolt, or penetrating injury to the head that inter-
rupts the functioning of the brain, at least momentarily.
Medical intervention varies considerably. During military
combat operations, some mild TBIs may go untreated
when there are no physical head wounds or neurological
signs of impairment. Medical personnel may not detect
injury, especially when more obvious, life-threatening
injuries require attention, and service members may not
seek care for a TBI if the injury does not appear acute.
Moderate and severe TBIs, however, are generally appar-
ent clinically through changes in consciousness or neuro-
logical impairment.
Criteria for a PTSD Diagnosis
According to current diagnostic criteria for PTSD, a per-
son must experience a traumatic event—involving death
or serious injury, or a threat to the physical integrity of
self or others—and react to the trauma with intense hor-
ror, fear, or helplessness.1 Sometime after that trauma, the
person must also develop symptoms that cause clinically
significant distress or impairment lasting for more than
one month. Those symptoms must be from each of the
following three symptom clusters:
Reexperiencing the traumatic event, such as having
recurring and distressing recollections or nightmares;
Avoidance of stimuli associated with the trauma, such
as thoughts, feelings, and conversations, along with
diminished responsiveness and loss of interest in activ-
ities; and
Hyperarousal, such as irritability, anger, hyper-
vigilance, insomnia, or difficulty with concentration.
For example, a person who experienced nightmares about
the trauma and had lost interest in daily activities but had
no symptoms of hyperarousal would not have PTSD,
according to those diagnostic criteria.
There are various forms of PTSD. Acute PTSD occurs
when the duration of symptoms is between one and three
months. Patients with symptoms extending for more
than three months are considered to have chronic PTSD.
Delayed-onset PTSD occurs when symptoms begin at
least six months after the trauma.
1. For more detail, see the Diagnostic and Statistical Manual of Men-
tal Disorders (DSM), 4th ed., rev. (Arlington, Va.: American Psychi-
atric Publishing, 2000). In previous editions, the DSM required
that the trauma be outside the range of usual human experience
but set no requirement for impairment. More recently, according
to the committee revising the DSM, the requirement that the
trauma result in horror, fear, or helplessness may be eliminated in
the 5th edition of the DSM, scheduled for release in 2013.

Course of PTSD
Among people who develop PTSD, the symptoms and
their intensity may differ over the course of the disorder.2
Some people recover without medical intervention; oth-
ers experience chronic symptoms persisting for years,
even decades; and still others have sporadic symptoms.
For most people who develop PTSD, symptoms appear
soon after the trauma, although the time between expo-
sure and symptoms sufficient for a clinical diagnosis of
PTSD varies.
Studies of Vietnam veterans who developed PTSD have
found that, for most veterans, the onset of PTSD
occurred during the first few years following combat
trauma, with the number of symptoms increasing rapidly
during that period. A study by Schnurr reported that
more than 60 percent of Vietnam veterans who
developed PTSD did so less than two years after entry
into the combat theater; fewer than 10 percent experi-
enced an onset of PTSD more than six years after enter-
ing the combat theater.
Researchers have found that a substantial portion of
PTSD patients develop chronic PTSD. Two studies—
one by Breslau and one by Kessler and others—indicate
that, for 20 percent to 40 percent of PTSD cases, symp-
toms abate within one year. According to Kessler and oth-
ers, as well as Conner and Butterfield, symptoms do not
improve substantially in more than one-third of PTSD
cases even after several years. (Because the populations,
treatment, and timing of treatment in those studies differ
from those in CBO’s analysis, the rates of remission
reported in the studies may not be applicable to more
recent combat veterans.)
Risk and protective factors for experiencing PTSD and
for subsequent recovery include demographic characteris-
tics, socioeconomic status, psychiatric history, and social
support. Among Vietnam veterans, women were more
likely than men to develop PTSD. Research also shows
that lower educational attainment, lower income, and
minority status place individuals at greater risk.3 The
presence of social networks and social support after a
stressor serves to protect against PTSD, particularly for
combat veterans. Finally, more frequent and intense
exposure to combat is strongly associated with the devel-
opment of PTSD.
Clinical Definition of TBI
The Centers for Disease Control and Prevention defines
TBI as an injury to the head arising from blunt or pene-
trating trauma or from acceleration-deceleration forces
that result in one or more of the following:
decreased level of consciousness;
amnesia regarding the event itself or events preceding
or following the injury;
skull fracture;
a neurological or neuropsychological abnormality such
as disorientation, agitation, or confusion; or
an intracranial lesion such as a traumatic intracranial
hematoma, cerebral contusion, or penetrating injury.4
Neurologists classify the severity of the TBI at the time of
the injury as mild, moderate, or severe. Mild TBIs

account for the vast majority of such injuries. Definitions
of mild TBI, also known as a concussion, vary within the
neurology community, but a generally accepted defini-
tion from the American Congress of Rehabilitation
Medicine specifies at least one of the following symptoms
after a blow to the head:
Loss of consciousness for no more than 30 minutes;
Loss of memory, lasting no longer than 24 hours, of
events immediately before (retrograde amnesia) or
after (posttraumatic amnesia) the injury;
Any alteration in mental state (being dazed, dis-
oriented, or confused, for example) at the time of the
injury; or
A score of 13 to 15 on a Glasgow coma scale (an
assessment of neurological functioning).5
Injuries above any of those thresholds are moderate
to severe TBIs. The continuation of multiple symptoms
may be labeled as postconcussional disorder or post-
concussive syndrome (PCS); however, those terms are
problematic because there is no single clinically validated
definition of the condition.6 Short- or long-term impair-
ment may affect memory, reasoning and problem solving,
language, speech, motor skills, physical functions, and
psychosocial behavior.
Course of TBI
Although the effects of, and recovery from, TBI differ
among individuals, impairment tends to be greater for
those with moderate or severe TBIs than for those with
mild TBIs. Moderate and severe TBIs are usually associ-
ated with damage to the brain that can be detected when
imaged.7 For people with moderate or severe TBI,
injuries to the brain—swelling of brain tissue, insufficient
blood flow, and pressure within the skull, for example—
may require surgery or medication. Recovery from
moderate or severe TBI ranges from full rehabilitation
to significant disability. Survivors of moderate or severe
TBI may suffer lasting consequences such as seizures,
nerve damage, behavioral abnormalities, and cognitive
and language difficulties.
Research findings on the course of recovery after mild
TBI vary widely, partly because of the difficulty in mak-
ing causal associations between the initial injury and
physical or cognitive problems following the injury.8
Frequently reported problems following a mild TBI
include headache, fatigue, dizziness, depression, and diffi-
culties with memory and concentration. However, many
problems associated with mild TBIs are nonspecific or
common to many conditions and widely experienced by
5. T. Kay and others, “Definition of Mild Traumatic Brain Injury,”
Journal of Head Trauma Rehabilitation, vol. 8, no. 3 (September
1993), pp. 86–87. Criteria by the Department of Veterans Affairs
and the Department of Defense for severity are largely consistent
with the above guidance, although they have one additional crite-
rion for mild TBI: Brain imaging results must be normal. Service
members who meet the other criteria for mild TBI but have
abnormal brain imaging results are rated as having moderate TBIs.
Service members who meet the criteria for more than one severity
level are rated at the higher severity. See Department of Veterans
Affairs and Department of Defense, VA/DOD Clinical Practice
Guideline for Management of Concussion/Mild Traumatic Brain
Injury, April 2009.
6. The DSM-IV and ICD-10 (International Classification of Diseases,
10th ed.) define the condition differently, which often results in
diagnostic disagreement. In addition, controversy surrounds the
diagnosis of the condition—specifically, whether symptoms that

the general population. Consequently, there is no objec-
tive way of determining whether ongoing problems are
caused by an earlier mild TBI or arise from other
conditions.
Most people with mild TBI report one or more symp-
toms or problems immediately after the injury; however,
medical evidence suggests that recovery typically occurs
within a matter of weeks or months, with improvement
most pronounced in the first months.9 In addition, some
studies indicate that between 5 percent and 20 percent of
people who experience a mild TBI remain symptomatic
after 12 months, although some researchers have reported
rates that exceed 20 percent, and others have argued
that rates are at the lower end of the range at most.10
Generally, studies report that a small subset of patients
experience one or more symptoms or limitations for years
after the injury. Repeated incidents of mild TBI (as may
occur from wartime explosions or in contact sports such
as football or hockey) may lead to more significant long-
term health problems.
Several studies have attempted to identify preinjury and
postinjury factors that may alter the course of recovery
from mild TBI.11 Researchers have found that the severity
and duration of symptoms can be reduced by providing
reassurance to patients and by providing education to
patients on both the course of TBI and expected recovery
from the condition. Few other factors have consistently
been shown to facilitate recovery from mild, symptomatic
TBI.

CBO
Appendix B:
Data and Methods
The Veterans Health Administration (VHA) pro-
vided the Congressional Budget Office (CBO) with
information on the frequency and costs of various health
care services for veterans of overseas contingency opera-
tions (OCO) for fiscal years 2004 through 2009. VHA
identified patients using a roster of OCO veterans that
was derived from the Department of Defense’s (DoD’s)
list of separated service members eligible for VHA bene-
fits. The roster is based on a combination of pay and
operational records and contains data fields describing
both general demographic characteristics and military
service information such as branch, rank, and deploy-
ment dates.
VHA data included virtually all OCO veterans seen at
VHA during fiscal years 2004 to 2009; fewer than 1 per-
cent of patients were deleted from the data set because
their information was incomplete. VHA provided the
data to CBO in groups organized by sex, age interval,
year of treatment, clinical service use, and clinical diagno-
ses. The diagnosis groups were defined to be mutually
exclusive, so that no patient was included in more than
one diagnosis group during the first year of treatment at
VHA; once classified, patients remained in the same
group for the entire sample period. A patient was identi-
fied as having post-traumatic stress disorder (PTSD) or a
traumatic brain injury (TBI) if he or she had at least one
medical encounter with VHA in which PTSD or TBI
was listed as a primary or secondary diagnosis. The iden-
tification of PTSD and TBI was broad, in that not all
patients with those diagnoses sustained those conditions
while deployed and, even among those who did sustain
the conditions while deployed, the conditions were not
necessarily related to combat. Patients who did not
receive a diagnosis of PTSD or TBI were also followed
from their first visit to VHA. From the time of the initial
clinic visit or inpatient stay, all patients were followed in
12-month increments. Service use and costs were aggre-
gated into totals by year of treatment.
CBO subsequently combined all patients into four mutu-
ally exclusive cohorts: no documented diagnosis of PTSD
or TBI, a diagnosis of PTSD and not TBI, a diagnosis of
TBI and not PTSD, or diagnoses of both PTSD and
TBI.1 Polytrauma patients were analyzed separately as a
fifth group because their usage was greater and their costs
substantially higher than those of other OCO patients.
Small cohort size was an issue in later treatment years:
CBO restricted its analysis to the first four years of treat-
ment for each entry group. As overseas contingency oper-
ations have continued, increasing numbers of service
members have deployed and separated from the military
and become eligible for VHA care; therefore, many
patients in CBO’s analysis entered the VHA system in the
last two years of the sample period (2008 and 2009), and
data accrued for them only for treatment years 1 or 2 (see
Figure B-1). Consequently, each group had fewer patients
in treatment year 4 than in treatment year 1. Because
CBO did not have data at the patient level, only group
totals and weighted averages were calculated. The lack of
patient-level data made it impossible to separate groups
by the year in which patients first used VHA’s services,
preventing CBO from following groups of patients dur-
ing the specific fiscal years in which they were treated.
VHA extracted data on patients’ use of services mainly
from its National Patient Care Database, which includes
1. Because of small sample sizes for female veterans and some age
groups, CBO does not report analyses along those dimensions.

information on patients from all of its clinical informa-
tion systems. Information on the use of various medical
services was available for 16 detailed categories, not all
of which were well populated. To provide a general over-
view, CBO classified the use of services as inpatient,
outpatient, or outpatient pharmacy. Use was measured in
days of inpatient hospital care and outpatient clinic visits.
A veteran may have had several outpatient visits on a sin-
gle day, each tallied separately. Pharmacy services were
measured as the number of 30-day equivalent prescrip-
tions filled.
The primary source of the cost data provided to CBO
was the cost-accounting system of VHA’s Decision
Support Service (DSS); a second source, the Fee Basis
database, included the cost of outside care paid for by
VHA. VHA combined those separate sources of cost
data, which captured most of the costs of services covered
by VHA, into unified data for CBO. Costs reflected
medical center-specific expenditures. Approximately
8 percent of total costs were not included, such as those
for capital, depreciation, the central office of the Depart-
ment of Veterans Affairs (VA), and some national pro-
grams. Because of those exclusions, the data used by
CBO were slightly different from the DSS data available
to most VHA researchers; therefore, other researchers
may not be able to reproduce the same results precisely.
The DSS system takes clinical and financial information
from other VHA databases and uses algorithms that
merge data and allocate costs across functional units.
Cost estimates of individual health care encounters are
also produced. Those costs include both direct and
indirect (overhead) components. Because the accuracy of
those costs depends on the quality of the feeder databases,
DSS data are subject to auditing at regular intervals. DSS
data are longitudinal and retrospective. VHA uses DSS
information extensively, including for the purpose of
financial allocation, and considers the data to be highly
reliable.
DSS computations to derive patient-level costs require
several steps. First, cost data from VHA’s core financial
and payroll systems are fed into DSS. Those cost data
reflect VHA’s actual outlays for salaries, supplies, and
contract services, as well as imputed costs for deprecia-
tion. At that level, expenditures are differentiated by type
of expense (labor category or supplies and equipment)
and by administrative service (nursing or laboratory
tests). Next, DSS assigns costs to functional cost centers
that involve either the direct provision of health care or

CBO
indirect support for health care. Cost centers that provide
care directly include primary care clinics and psychiatric
wards, whereas cost centers that provide indirect support
for health care include information technology support
and security. Using a standardized methodology, those
indirect costs are then allocated to departments providing
care directly within each facility. After all costs have been
assigned by function, unit costs for intermediate products
are constructed. Intermediate products are goods and
services used in providing care, such as blood draws, labo-
ratory tests, or doctors’ time during primary care visits.
Finally, all intermediate products and their prices are
assigned to individual patients to estimate the cost of
health care encounters.2
CBO categorized cost data as inpatient and outpatient,
with outpatient pharmacy costs included in the out-
patient category. VHA converted the costs provided to
CBO to fiscal year 2009 dollars on the basis of annual
increases in the average cost of a primary care visit
between fiscal years 2004 and 2009. CBO then indexed
those costs to 2011 dollars using the implicit price defla-
tor for gross domestic product.
Using those data, CBO calculated average costs per
patient with PTSD or TBI, or both, of health care ser-
vices for each treatment year by dividing costs in that year
(the numerator) by the number of patients who had ever
been diagnosed for PTSD or TBI and remained in the
sample that year (the denominator). Average costs for
those without PTSD or TBI were calculated using a simi-
lar method. Patients who used care from VHA for only a
single year or a single time were included in the denomi-
nator for all subsequent years, even years for which they
had no costs. In other words, CBO counted the entire
population of veterans diagnosed with PTSD or TBI
regardless of whether they continued to use VHA's ser-
vices after their first visit. That approach shows VHA's
average cost per patient to treat the entire population of
veterans in each diagnosis group (those diagnosed with
PTSD, TBI, both, or neither).
In calculating the average costs of PTSD- and TBI-
specific care, CBO used a similar methodology. VHA
provided two additional cost categories: “all PTSD care”
and “all TBI care,” which were used as the numerator.
The tallies of those categories should be viewed as rough
approximations of the costs of treating PTSD and TBI.
VHA assigned all costs associated with a medical encoun-
ter (for example, an inpatient stay or outpatient visit) as
“PTSD care” or “TBI care” whenever there was a primary
or secondary diagnosis of either condition. For the group
with both PTSD and TBI, if an encounter had both diag-
nosis codes, all the costs for that encounter were counted
in both categories—that is, they were assigned to the
costs of “PTSD care” and also to those of “TBI care”—so
estimates of dollars spent for the treatment of PTSD and
TBI are not mutually exclusive. For all groups, the total
cost of an entire visit was attributed to PTSD or TBI (or
both) even if there were several other diagnoses.
CBO used VHA’s “all PTSD care” and “all TBI care” cost
categories and, in addition, attributed the costs of diag-
nostic tests and pharmacy use, to which VHA does not
assign diagnosis codes, to PTSD or TBI care, according
to the group to which patients had been assigned. Inclu-
sion of diagnostic tests and pharmacy services increased
the costs for the subtotals for “all PTSD care” and “all
TBI care” by between 20 percent and 35 percent.
2. Although some researchers have used Medicare reimbursement
data to estimate health care costs, those data would not have been
useful for CBO’s analysis, which focuses solely on VHA’s costs.
VHA’s costs and Medicare reimbursement rates are structurally
different and therefore not directly comparable. As a health insur-
ance system, Medicare reimburses providers on the basis of a price
schedule for various services classified by diagnosis codes; negoti-
ated prices presumably reflect the providers’ costs, but they are not
equal to those costs. By contrast, VHA is a direct health care pro-
vider with an accounting system designed to measure the direct
and indirect costs of each health care encounter. In addition, ser-
vices are not necessarily comparable. For example, VHA hospital
stays include the costs of services provided by physicians; by con-
trast, Medicare’s reimbursements to hospitals for inpatient stays
do not.

Appendix C:
Interpreting Published Estimates of the
Prevalence of PTSD and TBI
Prevalence estimates for post-traumatic stress disorder
(PTSD) and traumatic brain injury (TBI) vary substan-
tially. Changes in diagnostic criteria over time, as well as
differences in the populations studied, diagnostic tools
used to identify cases, and the methodologies employed
all contribute to that variation.
PTSD Prevalence Among Current
Service Members Who Deployed to
Overseas Contingency Operations and
Veterans of Those Operations
PTSD was first included in the American Psychiatric
Association’s Diagnosis and Statistical Manual of Mental
Disorders in 1980; for a diagnosis of PTSD, a person
must have experienced a traumatic event and certain
symptoms related to that trauma. A number of studies
have addressed PTSD in service members or veterans.
Estimates of the proportion of service members with
PTSD generally range between 5 percent and 25 percent,
depending on the study’s methodology and the popula-
tion sampled.1
Some observers have looked to the prevalence of PTSD
among veterans of the Vietnam War. Widely quoted is
the National Vietnam Veterans Readjustment Study
(NVVRS), an extensive survey and analysis of mental
health problems among Vietnam War veterans. Research-
ers using those data estimated that 15 percent of male
Vietnam-theater veterans had combat-related PTSD at
the time of the survey (1988), and 31 percent had experi-
enced combat-related PTSD at some point in their lives
prior to the survey.2 A more recent reanalysis of a subsam-
ple of the NVVRS data found lower prevalence rates of
9 percent and lifetime prevalence of 19 percent as of
1988. The decrease in prevalence rates in the second anal-
ysis was largely attributed to a change in the methodology
used to identify a case of PTSD.3 While prevalence rates
among Vietnam War veterans are important for estimat-
ing the resources that group might require for future
treatment, those rates are not good indicators of the likely
prevalence rates for military members who have served in
the Iraq and Afghanistan conflicts. Previous research
shows that various factors—demographics, educational
attainment, social support, combat intensity and injuries,
1. The range includes studies that reported frequencies of PTSD
regardless of whether the study objective was to estimate the
prevalence in a population of service members or veterans. For
a survey of the literature, see Rajeev Ramchand and others,

bers Who Served in Iraq and Afghanistan: Possible Explanations,”

Vietnam for U.S. Veterans: A Revisit with New Data and Meth-

The diagnostic tool and methodology used in the reanalysis of the
NVRRS differed from those used in the earlier study. The change
in the diagnostic tool alone reduced the estimated prevalence of
PTSD by 3 percentage points. Adjusting for changes in the clini-
cal definition of PTSD and using additional data from personnel
records decreased the prevalence rate an additional 3 percentage
points.

and past psychiatric history, among others—affect
whether service members will develop PTSD, and
Vietnam veterans differ from veterans recently discharged
from the military in some of those respects.4
Several recent studies have estimated the prevalence of
PTSD among those who deployed to overseas contin-
gency operations in Iraq and Afghanistan. Many have
relied on the commonly used 17-item PTSD Checklist
(PCL), in which veterans report their own symptoms, to
screen for PTSD; relatively few of those studies surveyed
members of all four military services or included reserve
and National Guard as well as active-duty personnel.5 A
2008 RAND study based on a telephone survey of 1,965
service members and veterans who had returned from
overseas contingency operations found that 14 percent
screened positive for PTSD. Within that group, higher
rates were observed among Army soldiers and National
Guard and reserve personnel than among other groups;
higher rates were observed for those with longer deploy-
ments; and higher rates were observed for those seriously
injured during their deployment.6 A separate study by
Smith and others reported new cases of PTSD in as few
as 1 percent to 4 percent of deployed service members
in the Air Force who did not experience combat expo-
sure, but up to 9 percent for Army soldiers who had
experienced certain combat-related traumas or expo-
sures.7 Other studies have estimated the prevalence of
PTSD from data on service members’ responses to the
Department of Defense’s (DoD’s) screening test for that
condition.8 Some estimates based on that test were on the
higher end of the spectrum. For example, a study by
Milliken and others found that between 6 percent and
12 percent of active Army personnel and between 6 per-
cent and 13 percent of Army reservists screened positive
for PTSD immediately upon returning from deployment
to the Iraq war. The same study showed that assessments
conducted three to six months after deployment yielded
positive screening rates between 9 percent and 17 percent
for active soldiers and between 14 percent and 25 percent
for reserve soldiers.9
Issues in Reporting PTSD Prevalence Rates
There are two main problems in applying the published
rates of PTSD to the entire population of OCO veterans.
First, the studies relied on screening tools to establish a
case of PTSD, and those instruments may not produce
accurate estimates of the prevalence of the underlying
condition. Second, the samples used in the studies were
seldom representative of all personnel who deployed.
Screening Tools to Estimate PTSD Prevalence Rates.
Although studies usually estimate rates of possible
PTSD using a screening questionnaire, those tools do
not replace a clinician-determined diagnosis. Screening
questionnaires are not comprehensive and do not deter-
mine whether all relevant criteria for a diagnosis have
been met.10 Also, different researchers may use more or
less stringent criteria to estimate the number of PTSD
cases, which would result in dissimilar estimates even if
the researchers used the same sample of service members
and the identical screening tool.11 Finally, because screen-
4. For example, recent veterans are more likely to have completed
high school than were draftees during the Vietnam War. Also,
American society may be more supportive of its returning service
members now than it was during the Vietnam War.
5. Researchers may use different methods to determine whether an
individual screens positive using the PCL. Under the cluster
method, personnel screened positive if they reported at least one
intrusion symptom, three avoidance symptoms, and two hyper-
arousal symptoms at the moderate level or higher. An alternate
method requires assigning a number to the severity of each
symptom (“not at all” = 0 points through “extremely bothered” =
5 points). To screen positive for PTSD, a score of at least 50 on a
scale of 17 to 85 is often required.

administers the four-question Primary Care PTSD screen (PC-
PTSD) in the Post-Deployment Health Assessment and, again,

Health Reassessment.

Soldiers Returning from the Iraq War,” Journal of the American

pp. 2141–2148. The prevalence estimates presented in that study
are based on the DoD-administered Post-Deployment Health
Assessment. The range in rates is the result of two alternate
methods for determining PTSD: The lower rate reflects service
members’ endorsement of three or more symptom clusters from
the four-item screening instrument, and the higher rate reflects
the positive endorsement of two or more symptom clusters.

CBO
ing tools are imperfect, they generate false positives and
false negatives; the resulting prevalence estimates, there-
fore, may diverge from the true prevalence rates. For
conditions in which the underlying prevalence in the
population is relatively low, a screen may be more likely
to overestimate the number of cases, particularly when
used as a clinical tool designed to capture as many poten-
tial cases as possible.12
Subsamples of the OCO Population. Most of the pub-
lished studies on PTSD have examined a subsample of
service members who have deployed to overseas contin-
gency operations, often combat troops in the Army or
Marine Corps, and excluded the more numerous support
personnel (such as truck drivers or supply handlers) or
personnel from the Navy and Air Force. Although those
results may be important for estimating the prevalence of
PTSD in the highest-risk units, they cannot be directly
applied to the entire deployed force. Other military
occupations and service branches are likely to see lower
levels of combat when deployed and consequently to
experience lower levels of PTSD than the Army and
Marine ground combat forces that have deployed, all else
being equal. Even studies that attempt to survey the
entire deployed force may not be representative because
some service members may be more likely than others to
respond to a survey. Furthermore, service members may
not respond truthfully if they are concerned that report-
ing could result in stigma and possibly jeopardize their
careers or delay their return home.13 In addition, method-
ological attempts to mitigate effects of unrepresentative
samples may not be wholly successful. Because of those
factors, the samples analyzed may either understate or
overstate the prevalence of PTSD among service mem-
bers who deployed to overseas contingency operations.
TBI Prevalence Among Current Service
Members Who Deployed to Overseas
Contingency Operations and Veterans
of Those Operations
Measuring TBI in the OCO population also presents
challenges. TBI results from an injury to the head, and
the symptoms that follow the injury vary substantially.
Research on the prevalence of TBI has been limited by
inconsistent case definitions for TBI and the absence of
ongoing population surveillance systems before the
1990s. Even now, the number of TBIs attributable to
service in overseas contingency operations is difficult to
measure. Many cases of TBI may never be recorded
because medical attention may not have seemed necessary
at the time of injury and because the Veterans Health
Administration and the Department of Defense did not
institute their population-based screening programs until
2007 and 2008, respectively.
Although investigation of the prevalence of TBI has not
been as extensive as that for PTSD, some researchers have
estimated the number of OCO service members who
10. For example, the PCL (17-item checklist) and the PC-PTSD
(four-item screen) do not explicitly establish significant distress or
impairment in social, occupational, or other areas of functioning.
In addition, the PCL does not ask whether the person was exposed
to a traumatic event.
11. Milliken presented data using two thresholds: answering positively
to two or more questions and, alternatively, to three or more ques-
tions on the four-question PC-PTSD. Using the higher threshold
almost halved (to 6 percent) the number of PTSD cases for active
Army soldiers immediately after deployment.
12. A 2004 study by Annabel Prins and others estimated that the
PC-PTSD had a sensitivity of 0.77 and a specificity of 0.85 using
a three-out-of-four question threshold. Those values imply that
77 percent of service members with PTSD screen positive (sensi-
tivity equals 0.77), and 15 percent of those without the disease
also screen positive (specificity equals 0.85). CBO estimates that,
if the true population prevalence is 15 percent and 1,000 people
are screened, a total of 244 people (24 percent) would be expected
to test positive: 116 of the 150 people (77 percent) who have the
disease, and 128 of the 850 people (15 percent) who do not (the
false positives). In that case, the rate of screening positive is about
60 percent higher than the true prevalence of the disease. See

(PC-PTSD): Development and Operating Characteristics: Corri-
gendum,” Primary Care Psychiatry, vol. 9, no. 4 (2004), p. 151;

Recent Estimates of PTSD and TBI from Operations Iraqi Free-
dom and Enduring Freedom,” Journal of Rehabilitation Research
and Development, vol. 46, no. 5 (2009), pp. vii–xiii.
13. One study by McLay and others illustrates that type of reporting
problem. Using a sample of medical personnel within the Depart-
ment of Defense, the study found that delivering the PCL anony-
mously generated double the rate of positive PTSD cases than
found in PCL results that become part of a service member’s med-
ical record. However, generalizing those results is problematic
because the respondents to the anonymous screen were a small
subset of the larger population and may not have been representa-
tive. See Robert N. McLay and others, “On-the-Record Screen-
ings Versus Anonymous Surveys in Reporting PTSD,” American
Journal of Psychiatry, vol. 165, no. 6 (June 2008), pp. 775–776.

screen positive for TBI or continue to have symptoms of
TBI. Researchers generally estimate that the proportion
of service members deployed to overseas contingency
operations who experienced a TBI (including those who
were no longer symptomatic) is between 15 percent and
23 percent, depending on the study’s methodology and
sample; their estimates of the portion of service members
who continue to experience symptoms over the longer
term (that is, who continue to have symptomatic TBI)
range from 4 percent to 9 percent.
A study by Hoge and others found that 15 percent of
soldiers in two Army infantry brigades returning from
deployment to Iraq screened positive for experiencing
amild TBI.
14 A 2008 RAND study that was based on a
telephone survey of OCO service members and veterans
reported a probable TBI prevalence of almost 20 per-
cent.15 A paper by Terrio and others estimated that
23 percent of soldiers in an Army brigade combat team
returning from a one-year deployment to Iraq had experi-
enced a TBI while deployed.16 That paper also examined
the frequency of continued medical complaints that may
be attributed to TBI, including headache, irritability, diz-
ziness, balance problems, and memory difficulties. The
authors found that 9 percent of personnel within the bri-
gade reported at least one ongoing symptom potentially
related to TBI, and 4 percent reported a minimum of two
ongoing symptoms at the time of the screening, a few
days after returning home from deployment. By compari-
son, VHA researchers have found that 7 percent of OCO
veterans who are screened receive a diagnosis of symp-
tomatic TBI.17 In part because there are no validated
clinical criteria for symptomatic TBI, estimates from
these studies are not comparable.
Issues in Reporting TBI Prevalence Rates
The rates of TBI reported in those published studies
should not be interpreted as the prevalence for the whole
population of service members deployed in support of the
conflicts in Iraq and Afghanistan. Estimates of TBI in
those studies are problematic for several reasons: Studies
use different sets of diagnosis codes to approximate the
number of TBI cases; they rely on screening instruments
for TBI rather than clinical diagnoses at or near the time
of injury; and they use samples that are not representative
of the entire deployed force. Furthermore, even if the
prevalence of TBI could be precisely determined, the
extent of impairment and consequent need for continu-
ing medical care are unknown.
Diagnosis Codes to Estimate TBI Prevalence Rates.
Studies that provide estimates of TBI frequency based on
diagnosis codes are problematic. For one thing, not
everyone with a TBI will seek treatment and receive a
diagnosis, which leads to underestimates. For another,
there is no single diagnosis code to identify TBIs. The
codes identify several types of injuries to the head, distin-
guished by the section of the head injured rather than by
the severity of injury to the brain itself. Researchers have
employed different collections of codes to estimate the
number of TBIs.
Screening Tools to Estimate TBI Prevalence Rates.
Studies have generally relied on screening tools or ques-
tions that are based on the Brief Traumatic Brain Injury
Screen (BTBIS) to identify possible TBIs.18 The BTBIS
does not replace a clinician-determined diagnosis at the
time of injury. Indeed, the accuracy of the BTBIS is not
known because it has not been psychometrically validated
against clinicians’ diagnoses at or near the time of injury.

18. To view the questionnaire, see “3 Question DVBIC TBI Screen-
ing Tool Instruction Sheet,” available at www.dvbic.org/images/
pdfs/3-Question-Screening-Tool.aspx. That screening tool asks
service members to identify injuries that occurred during deploy-
ment by certain mechanisms such as an explosion or a fall; it asks
whether any injuries resulted in a change in consciousness, such as
“seeing stars,” immediately following the event; and it also asks the
respondents, “Are you currently experiencing any of the following
problems that you think might be related to a possible head injury
or concussion?” It does not ask whether symptoms may be related
to other causes. RAND researchers considered the test positive for
TBI if the individual endorsed any of the injuries listed in the first
question and reported any alteration of consciousness detailed in
the second question. Terrio used the same screening criteria but
followed up with a clinical assessment. Hoge queried soldiers on a
smaller set of changes in consciousness than the BTBIS offers.

CBO
When the BTBIS is compared with a structured clinical
interview that may occur several months after the injury,
VHA researchers have found that the screen correctly
identifies the vast majority of OCO veterans who remain
symptomatic but also falsely identifies a large number of
people.19 Because the screen was designed as a clinical
tool to identify as many cases of TBI as possible, studies
relying on that tool are likely to overestimate, perhaps
significantly, the prevalence of both TBI and TBI with
persistent symptoms. Also, the timing of the screening
may result in substantially different responses in the same
population.20
Sample Selection. Sample selection is also problematic
when estimating the prevalence of TBI, much as it is for
PTSD. Studies have tended to focus on combat troops
returning to their units. Even in the few studies that did
survey active-duty personnel from all four branches of
service, not just Army soldiers, certain groups of service
members were either undersampled or oversampled.
Although combat troops are much more likely to
experience a TBI (and thereby inflate estimates of TBI
prevalence), a sample of soldiers who return to their units
does not include severely injured service members who
have been medically evacuated from the combat theater;
excluding medical evacuees from the sample under-
estimates the prevalence of TBI.
Extent of Impairment. Finally, even if the number of
TBIs sustained in combat theater could be accurately
determined, an important issue remains in understanding
the impact of TBI on the health care needs of the OCO
population: The degree of impairment is unknown. Even
a clinical diagnosis at or shortly after a TBI occurs indi-
cates only that an injury was sustained; it does not reveal
the persistence or intensity of symptoms at the time of
the diagnosis. Indeed, the literature indicates that the vast
majority of individuals who experience a mild TBI
recover spontaneously over a period of a few weeks or
months. In addition, for some who remain symptomatic,
many of the neurological and physiological indicators
and limitations arising from TBI (headaches, memory
difficulties, sleep problems) are not specific to the injury
and may be caused by either the TBI or other conditions,
complicating clinical assessment of TBI.21 Studies that
report rates of symptomatic TBI show substantially lower
rates than studies that measure the number of service
members who sustained a TBI during deployment to a
combat theater.

Appendix D:
VHA’s Average Annual Costs for
OCO Veterans Who Continue to Seek Care
In this study, the Congressional Budget Office (CBO)
calculated average costs per patient of health care services
for each treatment year by dividing costs in that year (the
numerator) by the number of patients who ever used
VHA’s services and remained in the sample that year (the
denominator). (For the denominator for each treatment
year, see the number of potential patients in Table D-1.)
That method yields costs for specific groups of new OCO
veterans, including some who used VHA only once and
others who used VHA more frequently or even continu-
ally. Those results are presented in the main text of this
study.
An alternative way to calculate average costs in a treat-
ment year is to include in the denominator only those
patients who continued to receive health care in each sub-
sequent year. (For the denominator for each treatment
year using that method, see the number of patients using
VHA in Table D-1.) That method will produce higher
annual average costs per patient, because the total cost for
treating patients each year is divided by the number of
patients who used services in that year (consequently, the
denominator is smaller). In this appendix, CBO presents
average costs using the second method. The first
approach provides the cost for treating a given group of
veterans; the second approach provides the cost for treat-
ing a group of veterans who are continually seeking care.
After the first year of treatment, average annual costs for
patients using VHA were higher than for potential
patients, because some of the potential patients had no
VHA costs associated with them (see Table D-2). Differ-
ences in average costs for the two samples were most pro-
nounced for patients who had neither PTSD nor TBI.
For that category of patients, the average cost of treat-
ment in year 4 for patients using VHA ($2,300) was
more than twice the cost for potential patients ($1,000,
shown in Table 2 on page 19). Because so many veterans
with PTSD and with both PTSD and TBI continued to
use VHA care, differences in average cost between the
two samples were much smaller for veterans diagnosed
with those conditions. By treatment year 4, the average
cost for patients using VHA with PTSD ($5,100) was
34 percent more than for potential patients with PTSD
($3,800). For veterans with both PTSD and TBI, the
average annual cost for patients using VHA was only
$400 more than the cost for potential patients.
