Abstract:Objective To evaluate the effect of bundle intervention on reducing catheter-associated urinary tract infection (CAUTI). Methods Hospitalized patients with urinary catheterization in a tertiary first-class hospital were subjected to targeted monitoring of a baseline survey from January to December 2022 (pre-intervention). The main causes were found out, and bundle intervention measures were developed and implemented through plan-do-check-act (PDCA) tools from January to March 2023 (intervention period). The data from April to December 2023 (post-intervention) were collected, difference in catheter use rate and incidence of CAUTI before and after intervention were compared. Results The implementation rate of correctly hanging urine collection bags after intervention was 97.00%, the implementation rate of timely emptying urine collection bags was 91.72%, awareness rate of hand hygiene among patient’s family members was 79.13%, implementation rate of urinary catheter clamping during transportation was 74.79%, and daily evaluation implementation rate was 87.68%, which were higher than the pre-intervention rates of 85.63%, 80.47%, 62.75%, 60.00%, and 79.93%, respectively. The incidence of CAUTI decreased from 1.23‰ before intervention to 0.57‰ after intervention, the use rate of urinary catheter decreased from 5.53% before intervention to 5.37% after intervention. Differences of the above indicators were all statistically significant (all P<0.05). Conclusion Through targeted monitoring on CAUTI and PDCA quality tools, the weak links in healthcare-associated infection control are identified, more targeted prevention and control measures are formulated, the implementation of bundle intervention measures can reduce the incidence of CAUTI.
