Drug-Targeted Alerts for Acute Kidney Injury
Study Overview
Detailed Description
Acute kidney injury (AKI) carries a significant, independent risk of mortality among hospitalized patients. Recent studies have demonstrated increased mortality among patients with even small increases in serum creatinine concentration. International guidelines for the treatment of AKI focus on appropriate management of drug dosing, avoiding nephrotoxic exposures, and careful attention to fluid and electrolyte balance. Early nephrologist involvement may also improve outcomes in AKI. Without appropriate provider recognition of AKI, however, none of these measures can be taken, and patient outcomes may suffer. AKI is frequently overlooked by clinicians, but carries a substantial cost, morbidity and mortality burden.
Our research group recently conducted a large-scale multicenter randomized controlled trial of electronic alerts for AKI throughout the Yale New Haven Health System from 2018 to 2020. The trial, which enrolled 6,030 patients with AKI, randomized patients between usual care and an intervention group whereby providers received a general AKI alert informing them to the presence of AKI and the patient's recent creatinine trends, and provided a link to an AKI-specific order set. Our study showed that, overall, alerting physicians to the presence of AKI did not demonstrate a difference in the rate of our primary outcome of progression of AKI, dialysis, or death, nor were there any differences in process measures accessed (i.e. provider actions) between the two groups, however, there was substantial heterogeneity among the study sites. Given the highly heterogenous nature of AKI, a more personalized approach may be warranted. Further, this study enrolled all patients who developed AKI rather than a targeted subset of patients who may benefit, such as those AKI patients receiving potentially harmful kidney-toxic medications. In the present proposal, we seek to expand upon our prior study to determine if the use of medication targeted electronic alerts will modify provider behavior, particularly in regards to nephrotoxic medication use and cessation, in the care of hospitalized patients with AKI and/or reduce the rates of progression to AKI, dialysis, or mortality in hospitalized patients.
The current study is a randomized, controlled trial of a medication-targeted electronic AKI alert system. Using the Kidney Disease: Improving Global Outcomes (KDIGO) creatinine criteria, inpatients at 4 different teaching hospitals of the Yale New Haven Health System that have had at least one dose of a nephrotoxic agent of interest within 24 hours of AKI onset will be randomized to either usual care or a medication-targeted alert that informs the provider of the presence of AKI and the patient's recent exposures to the targeted classes of medications with an option to discontinue. The primary outcome will be a composite of AKI progression, dialysis, or mortality within 14 days of randomization. Secondary outcomes will focus on the rate of cessation of any medication of interest within 24 hours of randomization and various other best practice metrics.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Patients With Progression of AKI OR Dialysis OR Death
Time Frame: 14 days from Randomization
|
Progression of AKI is defined by an increase in KDIGO creatinine stage from time of randomization to the present.
Dialysis is defined by the receipt of hemodialysis, continuous renal replacement therapy or peritoneal dialysis.
Isolated ultrafiltration treatments will not be included.
Mortality will be determined from hospital records.
|
14 days from Randomization
