Trial Outcomes & Findings for Drug-Targeted Alerts for Acute Kidney Injury (NCT NCT02771977)

NCT ID: NCT02771977

Last Updated: 2024-02-15

Results Overview

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.

Participant Flow

Recruitment and enrollment was done automatically via our best practice alert, which analyzed hospitalized patients for inclusion and exclusion criteria and, if met, automatically enrolled and randomized patients to the usual care or alert group.

5,839 subjects were assessed for eligibility, with 779 excluded due to either the patient's admission dates being prior to the alert becoming active, the first alert firing after a discharge order, or because the patient was already randomized in a previous hospital admission. 5,060 patients were then randomized to alert versus usual care with zero loss to follow up.

Best practices assessed include: Avoidance of nephrotoxins (cessation of order or absence of de novo order of IV constrast agent, aminoglycoside, NSAID, or ACE inhibitor within 24 hours of randomization), fluid administration (administration of fluids within 24 hours of randomization), urinalysis order (with or without microscopy within 24 hours of randomization), documentation of AKI (by ICD-9 and ICD-10 codes during index hospitalization), monitoring of creatinine (at least one serum creatinine measurement occurring within 36 hours of randomization), documentation of urine output (within 24 hours of randomization), renal consult order during index hospitalization. Each metric above is binary. Outcome is reported as a composite best practice outcome representing the proportion of best practices achieved per subject.
