Among healthcare-associated infections, urinary tract infections (UTI) have a high incidence rate, and approximately 80% of cases with UTI are due to indwelling urinary catheters. Data of all 970 hospitalized patients with indwelling urinary catheters (excluding children) were used to determine the catheter utilization ratio, catheter-associated urinary tract infection (CAUTI) incidence rate, and medical condition of patients with CAUTI and suspected to identify methods for improving infection control. The catheter utilization ratio during the study period was 0.11 and the CAUTI incidence rate was 0.36 (1,000 catheter-day). Once a week, the facility where this study was conducted implements in-hospital rounds targeting patients with long-term indwelling urinary catheter who have had their catheters placed for ≥4 weeks for preventing the occurrence of CAUTI. After placing a urinary catheter, it is vital to regularly review its continued placement. The implementation of in-hospital rounds targeting patients with long-term indwelling urinary catheter may contribute to a decline in the catheter utilization ratio and CAUTI incidence rate. In this study, the duration of indwelling urinary catheters was >4 weeks in five out of eight patients with onset of CAUTI and suspected. This result may be assigned that further improvement may be expected by shortening indwelling urinary catheters durations in patients targeted for in-hospital rounds and strengthening intervention in patients with long-term indwelling urinary catheters.
