Abstract
Results Comparison between August 2012-July 2013 and August 2013-July 2014 (Table 1, Figures 1 and 2) shows that there was a fall of 57.2 % (2.4-1.0, p = 0.040) in the rate of urinary tract infection associated with a urinary catheter and a reduction of 13.4 % (from 0.24 to 0.21, p = 0.001) in the utilization rate of urinary catheters.
