A comparative multicentre study on the incidence of catheter-associated urinary tract infection between nitrofurazone-coated and silicone catheters.

The efficacy of nitrofurazone-coated urinary catheter in inhibitory activity of catheter-associated urinary tract infection (CAUTI) was evaluated. The incidence rate and onset of CAUTI after catheterisation of standard silicone urinary catheters and nitrofurazone-coated catheters was compared. There was no statistical significance between the two groups in the incidence rate of CAUTI. However, in patients who had indwelling urinary catheters for 5-7 days, the incidence rate of CAUTI was significantly lower in the experimental group. Logistic regression analysis showed that the two variables, including age and period of insertion, affected the incidence rate of CAUTI significantly. Nitrofurazone-coated catheters can be useful for inhibition of CAUTI in patients who have indwelling urinary catheter for 5-7 days and in old-age patients.
