Peritoneal dialysis infections are the leading cause of Peritoneal dialysis failure and are the most common complications. Efforts are made so that these are prevented, one of which is adding dressing to the exit site. However, recent observations have shown that non-dressing was an option for better exit site care.
An open label randomized controlled trial study among 122 patients, randomized to with dressing and without dressing groups, with a primary end point of determining the incidence of peritoneal dialysis infection between the two groups. Mann-Whitney U test was used to compare the continuous outcomes such as time to exit site infection / peritonitis / tunnel infection and Fisher’s Exact test was used to determine the difference of frequency between groups
Among the incidence of exit-site infection in patients on peritoneal dialysis, we observed no significant difference between those who utilized an exit site dressing and those who did not (16.13% vs. 13.33%, p=0.800). However, there was a difference in the causative organisms: 80% of ESI in the dressing group were due to gram-positive bacteria compared to 50% in the non-dressing group. Conversely, gram-negative bacteria was more prevalent in the non-dressing group (62.5%).
Those without dressing did not have increased incidence of peritoneal dialysis related infections versus patients with dressing. This entails that patients may do without dressing as a means to care for the exit site.
