Background and objectives: Catheter-associated urinary tract infections (CAUTIs) represent an important health care burden. We assessed the effectiveness of an evidence-based multimodal multidisciplinary intervention intended to improve outcomes by reducing the use of urinary catheters (UCs) and minimizing the incidence of CAUTIs in the Internal Medicine department of a university hospital.

Material and methods: A multimodal intervention was developed, including training sessions, urinary catheterization reminders, surveillance systems, and mechanisms for staff feedback of results. The frequency of UC use and incidence of CAUTIs were recorded in 3-month periods before (P1) and during the intervention (P2).

Results: The catheterization rate decreased significantly during P2 (27.8% vs. 16.9%; relative risk [RR]: 0.61; 95% confidence interval [95% CI]: 0.57-0.65). We also observed a reduction in CAUTI risk (18.3 vs. 9.8%; RR: 0.53; 95% CI: 0.30-0.93); a reduction in the CAUTI rate per 1000 patient-days (5.5 vs. 2.8; incidence ratio [IR]: 0.52; 95% CI: 0.28-0.94); and a non-significant decrease in the CAUTI rate per 1000 catheters-days (19.3 vs. 16.9; IR: 0.85; 95% CI: 0.46-1.55).

Conclusions: The multimodal intervention was effective in reducing the catheterization rate and the frequency of CAUTIs.
