Low sensitivity of the exit site scoring system in detecting exit site infections in peritoneal dialysis patients.

Introduction: To evaluate the utility of the exit site scoring system in diagnosing exit site infections, we compared its scores to the well established exit site categories outlined by Twardowski and Prowant.

Methods: We examined the exit sites of 50 patients on peritoneal dialysis. Each exit site was given a score ranging from "zero" to "≥ 4" according to the exit site scoring system.
