Abstract: | The incidence of bacteriuria, significant urinary tract infection, and cost associated with the use of two urinary catheter drainage systems were evaluated in a population of hospitalized adult males. A commercially available device comprised of a Foley catheter attached with a heat-shrunk plastic seal to the tubing of a closed drainage bag (preconnected system) was compared with a standard system that had the Foley catheter attached to the closed drainage bag after it had been inserted. Using a randomized prospective design, the performance of the preconnected system in 97 patients was compared with that of the standard system in 105 patients. Catheters were left in place a mean of 6.4 and 7.6 days in the respective groups. Bacteriuria occurred after catheter insertion in 11.3% of patients receiving the preconnected system and 13.3% of patients receiving the standard system (not statistically significant). When bacteriuria developed, it occurred within seven days of catheter insertion in 50% of instances, irrespective of drainage system employed, suggesting that manipulations related to catheter insertion were important in initiating bacteriuria. Significant urinary tract infections occurred in only 2% of all patients studied. The higher cost for purchasing the preconnected system was not warranted for the population of patients studied. |
