Dropping the urine culture: sustained CAUTI reduction using a UTI order panel

Abstract

Objective: We introduced a urinary tract infection (UTI) panel requiring symptom documentation and identification of special populations linked to reflex urine culturing and evaluated its impact on catheter-associated UTI (CAUTI) including during the COVID-19 pandemic. Design: Quasi-experimental encompassing 3 periods: pre-panel (January 2014-March 2015), post-panel (April 2015-March 2020), and post-panel COVID (April 2020-June 2022). Setting/participants: Tertiary care center inpatients. Methods: Poisson regression and interrupted time series (ITS) analysis evaluated changes in catheter days (CD), urine cultures (UC), and CAUTI measured by 1,000 CD and patient days (PD). National Health Safety Network standardized infection ratio (SIR) and standardized utilization ratio (SUR) data were analyzed. Results: UC per 1,000 PD decreased after implementation (pre-panel 36.9 vs 16.6 post-panel vs 14.4 post-panel COVID, all P
