Methods Medical records, nursing records, urine routine and urine culture of elderly patients aged 60 or above in a geriatric department from February 2008 to February 2010 were combined with data recorded by nosocomial infection supervisors to analyze the status of urinary tract infection caused by indwelling catheter. Results The rate of urinary tract infection in the 224 objects was 36.5% (82 cases). Factors related to urinary tract infection in elderly inpatients with indwelling catheter were age, gender, days of indwelling catheter use and its nursing care methods. Conclusions Nosocomial urinary tract infection rate can be effectively decreased by restrictedly controlling the use indication of indwelling catheter among elderly patients to minimize their use of such catheter, shortening the days of urinary catheter use, focusing on the control of primary diseases and intensifying the nursing care of the urinary catheter according to their infection status.
