Abstract

Objective: Hospital-acquired urinary tract infections (HUTI) represent a significant impairment in the quality of health care. Incidence in catheterized patients has been estimated at approximately 20%, however few data are available in urologic patients. We report a prospective surveillance program over 6 years in our urologic department and evaluate its evolution.

Methods: Population consists of all patients admitted to the urology ward for 48 hours or more over a 6-year period from 1994. Data recorded: age, gender, duration of stay, insertion and removal of catheters, diagnosis of HUTI.

Analysis: calculation of incidence, and incidence density for HUTI and for catheter-related HUTI, analysis of trends by chi(2) trend test.

Results: A total of 10,054 consecutive patients were included, 52% were catheterized. The median incidence of catheter-related HUTI in catheterized patients was 13.0%, the incidence density was 25.1 HUTI/1000 patient-days of catheterization. The proportion of HUTI and specific catheter-related HUTI patients decreased, respectively from 8.4% and 14.2% to 6.5% and 12.3% during the study period (p<0.05).

Conclusion: The rate of HUTI was not as high as previously reported, perhaps due to a controlled catheter policy. Surveillance was associated with a significant decrease in infection rates, suggesting a beneficial feedback effect. Evaluation of diagnoses and surgical procedures would ensure an optimal quality control program.
