Pharmacist review of discharge antibiotics for urinary tract infections in the emergency department

Abstract

Emergency medicine (EM) pharmacists provide high-quality patient care in a fast-paced environment by optimizing pharmacotherapy regimens and reducing medication errors. Current literature demonstrates higher rates of medication errors with antibiotics compared with other medication classes. The aim of this quality improvement (QI) project was to reduce medication errors by 25% from baseline for antibiotic discharge prescriptions for urinary tract infections (UTIs). This QI initiative utilized the Institute for Healthcare Improvement Model for Improvement to implement a UTI stewardship intervention and prospective pharmacist review of discharge prescriptions. Patients discharged from the adult ED with an electronic prescription for UTI treatment with select antibiotics were included. The primary outcome metric was the percent of medication errors, defined as a composite of appropriate antibiotic agent, dose, frequency, and treatment duration based on our local treatment algorithm. The balancing metric was time spent per order reviewed. Data over time were assessed using statistical process control charts. A total of 534 antibiotic prescriptions were reviewed from January 9, 2022 to May 31, 2023. The most common indication was cystitis (70%), followed by pyelonephritis (17.4%) and asymptomatic bacteriuria (12.5%). Composite error rate decreased from 64.2% to 5%. Duration of therapy was the most common baseline error and was reduced from 45.3% to 11.6%. Errors in agent, dose and frequency decreased from 19.7% to 3.5%, 10.3% to 0.8% and from 5.7% to 0%, respectively. The aim of this QI initiative was achieved through a series of interventions, including prospective review of discharge antibiotics for UTIs by EM pharmacists, which reduced medication errors. This project demonstrates EM pharmacists have a positive impact in optimization of antimicrobial therapy for the treatment of UTIs.
