Introduction This document is designed to accompany the 2015 Participant Use Data File (PUF) available for download on the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) website ( www.facs.org/quality-programs/acs-nsqip ). The sections contained herein will provide the user with information on how to request the PUF, the contents of the data files, the data collection background, the inclusion and exclusion criteria for cases and hospitals, the data limitations, and the data point definitions and descriptions. This user guide applies specifically to the 2015 PUF. Hospitals utilizing the PUF from a different year should refer to the user guide specifically tailored to that particular data set. 2. Data Request Process An individual who has an official appointment at a fully enrolled site and wants to obtain a copy of the ACS NSQIP PUF can do so by visiting www.facs.org/quality-programs/acs-nsqip and following the steps listed below: 1. From the ACS NSQIP main page (www.facs.org/quality-programs/acs-nsqip) the requestor can scroll down to the “Quick Links” box on the left side. Within that box you can click on the “Participant Use Data File” link. This will take you to the PUF information and request page. 2. Following a brief introduction and explanation of the various PUFs, the requestor can click on “Request Data Set.” 3. This will take the requestor to the Data Use Agreement. This is a 3-page document that implements the data protections of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) and the ACS NSQIP Hospital Participation Agreement. Delivery of the PUF is contingent on agreement to the terms and conditions specified within the Data Use Agreement. You can read the Data Use Agreement from this page or download the 3-page document. The requestor is then required to type in their first and last name and click on “Request Data File.” By clicking on “Request Data File” the requestor agrees to the terms and conditions of the Data Use Agreement. 4. Requestors will then be required to complete a brief online form to provide ACS with basic information about themselves, including the participating hospital in which they are currently employed and in what capacity, as well as how the requestor plans on using the PUF data. Once all of the required fields are completed, the requestor clicks “Submit.” 1 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 5. ACS NSQIP staff will review the request in a timely manner. Program contacts at participating sites will be contacted at this time to confirm the requestor’s affiliation with the hospital and confirm internal approval of the PUF request. 6. Following receipt and confirmation of the information submitted, an email will be sent to the requestor containing a username and password along with the URL to download the data. The web link will be active from the time of the email for 10 full days (240 hours). 7. The file will be available in three different formats (Text, SPSS, SAS) and depending on the connection speed should take between 5 and 30 minutes to download. 8. The requestor may be contacted to confirm receipt of the data file and allow for feedback on the delivery mechanism, data points contained, and data file format. 3. File Description Each summer/fall a PUF will be made available for the previous calendar year’s data. The PUF is available in one of three different formats - Text, SAS, and SPSS. In 2008, we provided an additional file that contains SAS and SPSS codes for constructing RACE variable that was available in previous years. The 2015 file contains 273 variables for each case, and a variableby-variable description is provided starting on page 13. A brief description of the different formats follows: File Name ACS_NSQIP_PUF15_v2.txt Type tab delimited TXT file Uncompressed File Size 1.4 GB ACS_NSQIP_PUF15_v2.sas7bdat SAS 9.2 data file 5.1 GB ACS_NSQIP_PUF15_v2.sav SPSS 16.0 data file 2.9 GB Construct_RACE_Codes.txt Notepad file 2 3KB Description Contains 273 HIPAA compliant variables on 885,502 cases submitted from 603 sites in 2015. Same information as stated above in TXT data format. Same information as stated above in TXT and SAS data format. Contains SAS and SPSS codes for constructing RACE variable that was available in 2005, 2006 and 2007. ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 4. Data Variable Updates There are several changes to the “Data Variables” list beginning on Page 13 of this document. The “Variable Definition” column (as it appeared in the PUF User Guides from 2005-2014) has been removed. It has been replaced by a column titled: “Search Term in Chapter 4…” Beginning with this PUF, abbreviated definitions have been removed from the Variable Definition field. So that investigators will have ready access to complete and authoritative variable definitions (rather than past definitions which may be incomplete and potentially misleading with respect to nuanced clinical features of importance to the investigator), the “Search Term in Chapter 4…” field will now contain a search term that will locate the complete definition in Chapter 4 of the “ACS NSQIP Operations Manual” - the authoritative variable definition reference manual used by SCRs. Please be aware that Chapter 4 definitions are year specific, though dramatic changes are rare. Variables names have been reconciled so that you can copy the entire text within an individual cell from the column titled “Search Term in Chapter 4…” in the User Guide, and paste it into a search field (you can create a search field by simultaneously hitting Ctrl and F on your keyboard) in Chapter 4. Once the text is copied into the search field and enter is hit, you will see the variable definition and other information pertinent to that particular variable. To support this new process, investigators receiving the PUF will have the opportunity to download a Chapter 4 corresponding to the specific PUF year (beginning with data for 2015). Appropriate definitions will continue to be provided in the “Search Term in Chapter 4…” field for those variables that are constructed specifically for the PUF and do not exist in Chapter 4. Chapter 4 will be made available to you for download with the rest of your requested PUF files or by contacting your hospital’s Surgical Clinical Reviewer (SCR). Data Use Agreements will now apply to the use and distribution of Chapter 4, as well as PUF data itself. A new variable, “PUFYEAR” has been added to the dataset. This variable will allow you to identify the appropriate Chapter 4 for data that has been merged across several years. In prior years we have retained data fields for historical variables that are no longer collected and inserted missing values. Beginning this year, we are dropping all variables that are not currently collected. Thus, the number of variables included in the Essential PUF is fewer this year than in past years. Also, because the position of data fields is no longer consistent across years, it will no longer be possible to join data across years by merely concatenating files. Files will need to be merged by variable name using appropriate statistical software. 3 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 5. Data Collection Background and Data Quality The ACS NSQIP collects data on over 150 variables, including preoperative risk factors, intraoperative variables, and 30-day postoperative mortality and morbidity outcomes for patients undergoing major surgical procedures in both the inpatient and outpatient setting. A site’s trained and certified Surgical Clinical Reviewer (SCR) captures these data using a variety of methods including medical chart abstraction. Required data variables are entered via web-based data collection to the ACS NSQIP website. Portions of the data may be automatically populated by a software program that was developed to extract data from the participating hospital’s existing information systems. Requestors should contact the SCR(s) at their hospital for detailed information on how the hospital collects its ACS NSQIP data. To ensure the data collected are of the highest quality, the ACS NSQIP has developed a host of different training mechanisms for the SCRs and conducts an Inter-Rater Reliability (IRR) Audit of selected participating sites. In addition to an initial web-based training program, the ACS NSQIP requires SCRs to complete a series of web-based training modules followed by a certification exam that must be retaken annually. The modules and certification exam focus on the program, processes, and analysis; preoperative, intraoperative, and postoperative definitions; and case studies. These modules are complemented by a growing online decision support system that ensures the SCRs have the knowledge and resources available to collect high-quality data. The IRR Audit is a fundamental tool of ACS NSQIP to assess the quality of the data collected at participating sites. The process involves the review of multiple charts, some of which are selected randomly and others selected based on criteria designed to identify potential reporting errors. For example, cases with five or more preoperative risk factors and no reported mortality or morbidity or cases with two or fewer preoperative risk factors and reported mortality or morbidity will be selected for chart review. Operating room logs are also audited to ensure correct sampling of cases. The combined results of the audits completed to date revealed an overall disagreement rate of approximately 2% for all assessed program variables. The ACS NSQIP has determined that an IRR Audit disagreement rate of 5% or less is acceptable. Sites that have higher than a 5% disagreement rate are not provided a hospital odds ratio in the ACS NSQIP Semiannual Report and may be required to undergo an additional audit following training and education recommendations from the ACS NSQIP. 4 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 6. Sampling Process and Case Exclusion Criteria Sites participating in the ACS NSQIP can do so in a variety of options that cover general/vascular surgery, multispecialty surgery, or procedure targeted (reported separately). Each participation option includes a systematic sampling process that is described below. Systematic Sampling Process Larger institutions normally experience a significant volume of surgical cases. This presents the problem of managing an overwhelming workload. In order to prevent bias in choosing cases for assessment, a systematic sampling process was developed. An important tool to utilize while performing the systematic sampling process is the 8-Day Cycle Schedule. The 8-day cycle works as follows: If the first ‘cycle’ begins on a Monday, it continues through to include the following Monday (an 8-day period of time). The next cycle begins on Tuesday and continues through to include the following Tuesday. And so on. This process assures that over time cases have equal chances of being selected from each day of the week. Note: There are some exceptions to the systematic sampling inclusion. Hospitals participating in the Small & Rural option will collect all ACS NSQIP®-eligible cases at their hospital. Hospitals participating in Essentials (Multispecialty only) or in the Procedure Targeted (General/Vascular OR Multispecialty) options are provided with sampling requirements specific to their site and may opt to collect more than the specified sampling requirements if resources allow. Case Exclusion Criteria The following exclusion criteria were applied to cases collected in 2015. For the current inclusion/exclusion criteria please contact the ACS NSQIP Clinical Support Team at clinicalsupport@acsnsqip.org. Minor Cases (all cases that are not considered Major) Patients under the age of 18 years. Patient for the case in question has been assigned with an ASA score of 6 (brain-death organ donors). Cases involving Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Trauma cases: Any patient that meets the trauma exclusion criteria will be excluded. Transplant cases: For any patient who is admitted to the hospital and has a transplant procedure, that transplant procedure and any additional surgical procedure during the transplant hospitalization will be excluded. 5 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 Cases beyond three per cycle for limited cases: For each program option (excluding Small & Rural), only a maximum of three cases from each of the below procedures should be included per 8-day cycle. Any case beyond the case limit of three for any of these procedures should be excluded. o Inguinal Herniorrhaphies o Breast Lumpectomies o Laparoscopic Cholecystectomies o TURPs and/or TURBTs (This limit does not apply for Procedure Targeted sites that are targeting TURPs.) Cases beyond the required number per your site’s contract for each cycle. A return to the operating room that is related to an occurrence or complication of a prior procedure Multiple NSQIP assessed cases within 30 days: Any patient who already has a NSQIPassessed procedure entered within the previous 30 days at your site should be excluded. Only one NSQIP®-assessed procedure can be abstracted patient, per 30 days, for each Hospital Exclusion Criteria In addition to the case inclusion/exclusion criteria, hospital inclusion/exclusion criteria are also imposed. To maintain the highest level of data quality, only cases included in the odds ratio analysis are included in the PUF. These cases go through an additional level of scrutiny as they are passed from data collection to statistical analysis. A site is excluded from the odds ratio calculations and the PUF if it fits any of the following criteria: 30-day follow-up rate is under 80% Inter-Rater Reliability Audit disagreement rate is over 5% Measures Sites Excluded Due to the small number of “Measures” sites enrolled in ACS NSQIP, cases from “Measures” sites have been removed from the PUF dataset in order to protect against possible identification of those sites and cases. 7. Data Limitations While every effort has been made to make the PUF as complete as possible, the data do have certain limitations. Some of these limitations have been deliberately introduced to safeguard the privacy of patients (such as removal of absolute dates). Other limitations are due to resource constraints (such as the collection of generic surgical variables only, except for the procedure 6 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 targeted option, which is reported separately). The following items represent the most salient limitations of the data: Because such a wide variety of operations are tracked, the variables are necessarily generic in nature. This limitation may pose difficulties for researchers attempting indepth research on specific conditions or operations. However, surgical Targeted PUF datasets are now available which address target-specific predictors and outcomes for many types of operations. While the sex and race distributions are reasonably representative of the national surgery patient population, only patients over the age of 18 are available for assessment, so the age distribution is somewhat truncated. Patients over the age of 90 are also grouped into a 90+ category to prevent cases from being identifiable due to unique data. Patients are followed after surgery for 30 days. Complications or death after that period are not included. Hospitals may follow patients longer than 30 days, but this data is not reported by NSQIP. In order to comply with HIPAA requirements, all absolute dates have been removed. The most critical of these is the date of surgery, which has been reduced to year of surgery only. Some dates (hospital entry, dates of laboratory tests, and so on) have been recoded into durations e.g. Date of Admission and Date of Discharge is recoded into Hospital Length of Stay. In order to comply with the Hospital Participation Agreement (HPA) that is agreed to between the ACS and participating sites, facility identifiers as well as geographic information regarding the case have been removed. The HPA stipulates that the ACS does not identify participating sites. Site identification could be possible even with blinded identifiers through advanced statistics. A stipulation of access to the PUF is completion of the Data Use Agreement that strictly prohibits attempts to identify hospitals, health care providers, or patients. While many risk factors are tracked, preventative measures are not recorded which can lead to an underestimation of the risk of certain conditions when such measures are routinely taken before surgery. The data are submitted from hospitals that are participating in the ACS NSQIP and do not represent a statistically valid nationally representative sample. 7 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 Most patients do not receive all possible preoperative laboratory tests, so some of these variables have a high percentage of missing values (15% to 45%, depending on the tests). This high percentage of missing data can make it problematic to use these variables in a traditional logistic regression model as well as in many other types of analysis. This list may not include all data limitations and additional limitations may apply in future versions of the data. Graft failure, Coma, and Peripheral Nerve Injury Data Update As first identified and reported in December of 2014, we have identified a problem in reported results for three outcome variables that existed in the Classic program, but did not exist in Essentials, between 2011 and 2013. As it is mandatory to report outcome variables, we have historically converted the absence of an affirmative response (i.e., missing data) to “No Complication”. This otherwise appropriate procedure was mistakenly applied to three outcome variables which were dropped from Essentials beginning in 2011 (Graft failure, Coma, Peripheral Nerve Injury). This logic resulted in “No complication” being assigned to missing data coming from Essential sites where, in fact, no data was being collected for these three outcomes. For the 2013 SAR (when Classic no longer existed) this isn’t much of a problem as users would clearly know that something was wrong when 100% of the cases had “No complication” (for 2014 missing values were inserted for these historical outcome variables rather than “No complication”). However for 2011 and 2012, when some sites were Essentials and some Classic, a PUF user would see a strange, precipitous, drop in event rates for these outcomes. Because of this problem, Graft failure, Coma, and Peripheral Nerve Injury should not be considered accurate for any PUF after 2010. 8.

Frequently Asked Questions Request Process Q: A: Who has access to this file? Any individual with an official appointment at a fully participating site will be given access to the file following completion of the Data Use Agreement and a short set of questions that are available on the website. Q: A: Is the file available to individuals from nonparticipating sites? At this time the data files are only available to individuals with official appointments at fully participating sites. Q: I am at a NSQIP-participating site and would like to work on a research project with others from a different site that is not participating. Will I be allowed to do that? Yes, however, the NSQIP affiliated researcher must be the lead investigator on all PUFbased research projects and is responsible for the PUF dataset, even if forwarded to someone else. The non-participating collaborator must also sign the DUA. A: Q: A: How do I obtain a copy of this file? Please see the “Data Request Process” on page 1 of this document for a step-by-step approach on how to do so. Contents of the Files Q: A: What is in this file? The file contains Health Insurance Portability and Accountability Act (HIPAA) deidentified data from sites participating in the ACS NSQIP that received risk-adjusted reports in 2015. The variable name, variable label, data definition, and other pertinent information are provided in Section 10: Data Variables and Definitions. Q: A: Are site identifiers included in the database? At this time we do not provide any geographic or site-specific identification. We took this approach to ensure the privacy of both the participating sites and surgeons. Q: A: Are there surgeon-specific identifiers included in the database? At this time we do not provide any surgeon-specific information. We took this approach to ensure the privacy of both the participating sites and surgeons. 9 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 Q: A: Are other PUF data sets available? 19 other PUF files are available for request / download: PUF Year 2005/2006 2007 2008 2009 2010 2011 2012 2013 2014 2011/2012 2013 2014 2011/2012 2013 2014 2014 2014 2014 2014 PUF Type Essentials Essentials Essentials Essentials Essentials Essentials Essentials Essentials Essentials Colectomy Colectomy Colectomy Vascular Vascular Vascular Gynecology Hepatectomy Hysterectomy Pancreatectomy Cases 152,490 211,407 271,368 336,190 363,431 442,149 543,885 651,940 750,397 16,981 21,505 25,262 655 4,292 4,029 500 3,064 19,283 5,187 Sites 121 183 211 237 258 315 374 435 517 121 154 203 71 83 83 19 92 91 106 Q: A: Why does the PUF exclude specific dates? In order to release the PUF, certain adjustments to the data are required to ensure proper protection of patient information. To meet these requirements, we remove all elements of dates (except quarter of admission and year) for dates directly related to an individual. For more information on the 18 data elements that are required for removal, please visit http://privacyruleandresearch.nih.gov/ or http://privacyruleandresearch.nih.gov/pdf/HIPAA_Booklet_4-14-2003.pdf. Q: I am the Surgeon Champion or Surgical Clinical Reviewer from a site that has records in the PUF and would like to know which specific records are ours. At this time we do not provide site identification of any cases in the PUF, even selfidentification. A: 10 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 Values in the Data Q: A: Q: A: Q: A: Q: A: Q: A: For each of the following complications, Pneumonia, On Ventilator > 48 hours, Urinary Tract Infection, and Bleeding Transfusion, one case did not have a known duration from operation to complication. Why is that? In each of these complications the case had an invalid date which inhibited the calculation of duration. The number of days from operation to complication variable is coded as -99 for these cases. What are the probability scores for mortality and morbidity and how often are they calculated? The probabilities of mortality and morbidity are provided in this database for all surgery cases in 2015. These probabilities are derived using hierarchical regression analysis, but based only on patient-level effects. They represent the probability (0 to 1) that a case will experience a morbidity or mortality event based on pre-existing conditions. These probabilities are calculated every six months for the previous 12 months of data so the algorithm used to generate the predicted values changes over time as does the data used to create the algorithm. Which calculated probabilities of mortality and morbidity are supplied in this data set? The probabilities of mortality and morbidity for all surgical cases used in the riskadjusted analysis in 2015 are provided. Why do some of the preoperative lab values have duration from lab to operation, but a value of -99 for the lab value? The results of the lab tests can be entered manually and thus are susceptible to data entry error. Depending on the preoperative lab variable roughly 1% of the cases had invalid values and these invalid values were set to -99 to simplify analysis. It is also possible that some cases have valid lab values, but are missing duration from lab to operation variable. This discrepancy is also related to a data entry error and the program continues to improve the data collection software to minimize the potential for data entry errors. When performing analysis on the five digit CPT codes in the Other and Concurrent variables, how should I interpret those cases with a valid 5 digit CPT code but a CPT description set to NULL? If the case has a valid five digit CPT code that procedure occurred and should be evaluated as such. The CPT description is a secondary variable and provided for 11 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 convenience. In the processing of large amounts of data some descriptions are purposefully or inadvertently removed. File Formats Q: A: In what file formats are the data available? The data files are made available in a tab delimited TXT file, an SPSS file, and a SAS file. 12 ACS NSQIP 2015 PUF USER GUIDE | OCTOBER 2016 Advisement: When a change in definitions across PUF years is noted, users should attend to this if they merge files. It is suggested that they evaluate variable categories across years and combine them in a manner appropriate to their research objectives.
