Background: Gram-positive bacteria are the major causative pathogens of peritonitis and exit site infection in patients undergoing peritoneal dialysis (PD). We investigated the cost-effectiveness of regular application of mupirocin at the exit site in PD recipients from the perspective of health care providers in Hong Kong.
Methods: A decision tree was designed to simulate outcomes of incident PD patients with and without regular application of mupirocin over a 1-year period.
