Decreasing Catheter-Associated Urinary Tract Infections in the Neurological Intensive Care Unit: One Unit's Success.

BACKGROUND: Catheter-associated urinary tract infections are preventable adverse outcomes that increase hospital morbidity, mortality, and costs. These infections are particularly prevalent in intensive care units.
OBJECTIVES: To describe the success of an 18-bed neurological intensive care unit in using several nurse-implemented strategies that reduced the number of catheter-associated urinary tract infections.
METHODS: A prospective, interventional design with application of evidence-based practices to reduce catheter-associated urinary tract infections was used.
RESULTS: Before implementation of the strategies, 40 catheter-associated urinary tract infections were reported for 2012 and 38 for 2013. The standardized infection ratio was 2.04 for 2012 (95% CI, 1.456-2.775) and 2.34 (95% CI, 1.522-3.312) for 2013. After implementation of the strategies, significantly fewer catheter-associated urinary tract infections were reported. In 2014, a total of 15 infections were reported, and the standardized infection ratio was less than 1.0 (95% CI, 0.685-1.900).
CONCLUSIONS: Application of current evidence-based practices resulted in a substantial decrease in the number of catheter-associated urinary tract infections and a lower standardized infection ratio. These findings support current recommendations for "bundling" to maximize outcomes. ©2017 American Association of Critical-Care Nurses.
