Clinical Decision Support for Acute
Kidney Injury and Hospital Survival
doi: 10.1681/ASN.
CONCLUSION
Implementation of a CDSS for AKI resulted in
a small but sustained decrease in hospital
mortality, length of stay and use of dialysis.
Clinical Decision Support System
•Derives reference serum creatinine from
historical values in EMR
•Flags creatinine changes and KDIGO stage
OUTCOMES
Outcomes were measured pre- and post-
implementation of a Clinical Decision

What's in the IV bag? Studies show safer
option than saline
•BY MARILYNN MARCHIONE, AP CHIEF MEDICAL WRITER
Feb 27, 2018, 5:10 PM ET
Conclusions
•Markers of cell-cycle arrest appear to be robust measures of risk
for AKI (manifesting in the next 12-24h)
•Underlying biology suggestive of an “alarm-phase” marker
before actual damage has a occurred.
•A “KDIGO Bundle” can reduce AKI when applied to biomarker
positive patients after cardiac surgery.
•Nephrotoxic drug exposure accounts for as much as 30% of AKI
and may contribute to more than half.
•Improved risk assessment and early detection can prevent Acute
Renal Failure.
•Stop using saline!

RISK FACTORS FOR AKI/D-AKI
Description
Risk Factors for Critically Ill
Susceptibilities
Age, black race, female,
history of diabetes,
history of hypertension, previous AKI episode,
elevated baseline serum creatinine
Exposures
Nephtoroxin
administration, trauma, burn,
circulatory shock, sepsis, high risk surgery,
hypotension, fluid overload
Drug
-specific
Exposure
Nephrotoxin
treatment duration, cumulative
dose, total daily dose, pharmacokinetic and
pharmacodynamic
drug interactions,
nephrotoxic burden
▪Concomitant nephrotoxin administration was an
independent predictor of AKI
▪53% greater odds of developing A KI for every
nephrotoxic drug received (OR 1.53; CI 1.09-2.14)
▪Significant association between cumulative number of
exposures and risk of AKI (p = 0.02) but no association
between the each type of exposure and A KI (p = 0.22)

continued.

over next 2 weeks.
•Tracheostomy performed.
•Transferred to lower level of care.
Case of Acute Kidney Injury
Teaching Points
•Not a single insult to the kidney

and Piperacillin-Tazobactam.
