Objective: Asymptomatic bacteriuria (ASB) denotes asymptomatic carriage of bacteria within the urinary tract and does not require treatment in most patient populations. Unnecessary antimicrobial treatment has several consequences, including promotion of antimicrobial resistance, potential for medication adverse effects, and risk for Clostridiodes difficile infection. The aim of this quality improvement effort was to decrease both the unnecessary ordering of urine culture studies and unnecessary treatment of ASB. Methods: This is a single-center study of patients who received care on 3 internal medicine units at a large, academic medical center. We sought to determine the impact of information technology and educational interventions to decrease both inappropriate urine culture ordering and treatment of ASB. Data from included patients were collected over 3 1-month time periods: baseline, post-information technology intervention, and post-educational intervention. Results: There was a reduction in the percentage of patients who received antibiotics for ASB in the post-education intervention period as compared to baseline (35% vs 42%). The proportion of total urine cultures ordered by internal medicine clinicians did not change after an information technology intervention to redesign the computerized physician order entry screen for urine cultures. Conclusion: Educational interventions are effective ways to reduce rates of inappropriate treatment of ASB in patients admitted to internal medicine services.
