Abstract:

Background: Many hospitals struggle to prevent catheter-associated urinary tract infection (CAUTI). Objective: To evaluate the effect of a multimodal initiative on CAUTI in hospitals with high burden of health care-associated infection (HAI). Design: Prospective, national, nonrandomized, clustered, externally facilitated, pre-post observational quality improvement initiative, for 3 cohorts active between November 2016 and May 2018. Setting: Acute care, long-term acute care, and critical access hospitals, including intensive care and non-intensive care wards. Participants: Target hospitals had a high burden of Clostridioides difficile infection plus central line-associated bloodstream infection, CAUTI, or hospital-onset methicillin-resistant Staphylococcus aureus bloodstream infection, defined as cumulative attributable differences above the first tertile in the Targeted Assessment for Prevention (TAP) strategy. Some additional nonrecruited hospitals also joined. Intervention: Multimodal intervention, including Practice Change Assessment tool to identify infection prevention and control (IPC) and HAI prevention gaps; Web-based, on-demand modules involving onboarding, foundational IPC practices, HAI-specific 2-tiered approach to prioritize and implement interventions, and TAP resources; monthly webinars; state partner-led in-person meetings; and feedback. State partners made site visits to at least 50% of their enrolled hospitals, to support self-assessments and coach. Measurements: Rates of CAUTI and urinary catheter device utilization ratio. Results: Of 387 participating hospitals from 23 states and the District of Columbia, 361 provided CAUTI data. Over the study period, the unadjusted CAUTI rate was low and relatively stable, decreasing slightly from 1.12 to 1.04 CAUTIs per 1000 catheter-days. Catheter utilization decreased from 21.46 to 19.83 catheter-days per 100 patient-days from the pre- to the postintervention period. Limitations: The intervention period was brief, with no assessment of fidelity. Baseline CAUTI rates were low. Patient characteristics were not assessed. Conclusion: This multimodal intervention yielded no substantial improvements in CAUTI or urinary catheter utilization. Primary Funding Source: Centers for Disease Control and Prevention.
