A Bundle-Based Approach to Prevent Catheter-Associated Urinary Tract Infections in the Intensive Care Unit.
Catheter-associated urinary tract infections are the second most common health care-associated infections, occurring most frequently in intensive care units. These infections negatively affect patient outcomes and health care costs.
The targeted institution for this improvement project reported 13 catheter-associated urinary tract infections in 2018, exceeding the hospital's benchmark of 4 or fewer such events annually. Six of the events occurred in the intensive care unit. Project objectives included a 30% reduction in reported catheter-associated urinary tract infections, 20% reduction in urinary catheter days, and 75% compliance rating in catheter-related documentation in the intensive care unit during the intervention phase.
This project used a pre-post design over 2 consecutive 4-month periods. The targeted population was critically ill patients aged 18 and older who were admitted to the intensive care unit. A set of bundled interventions was implemented, including staff education, an electronic daily checklist, and a nurse-driven removal protocol for indwelling urinary catheters. Data were analyzed using mixed statistics, including independent samples t tests and Fisher exact tests.
No catheter-associated urinary tract infections were reported during the intervention period, reducing the rate by 1.33 per 1000 catheter days. There was a 10.5% increase in catheter days, which was not statistically significant (P = .12). Documentation compliance increased significantly from 50.0% before to 83.3% during the intervention (P = .01).
This bundled approach shows promise for reducing catheter-associated urinary tract infections in critical care settings. The concept could be adapted for other health care-associated infections.
