title: Implementation of a continuous quality improvement program reduces the occurrence of peritonitis in PD.
abstract: OBJECTIVE
  To investigate the causes of peritonitis in patients with peritoneal dialysis (PD) using continuous quality improvement (CQI) to develop effective interventions and reduce the occurrence of peritonitis.
  
  
  METHODS
  A quality control team consisting of 10 members, including the department head, four nephrologists and four nurses, all specialized in PD care, and the head nurse, was established at the Peritoneal Dialysis Center of the Third Xiangya Hospital of Central South University. All patients with peritonitis occurring between 1 July 2010 and 31 December 2011 (pre-CQI period) were analyzed and compared with data obtained between January 2012 (implementation of CQI) and March 2013 to investigate possible causes of peritonitis and to develop corresponding interventions. Fishbone analysis, including laboratory parameters, was carried out monthly.
  
  
  RESULTS
  Gastrointestinal tract dysfunction, nonstandard procedures and malnutrition were found to be the top three risk factors for peritonitis. Gastrointestinal tract dysfunction was the likely cause of peritonitis in 42.8% of the subjects before CQI and 36.0% after CQI (p<0.05). Nonstandard procedures were the cause of peritonitis in 33.3% of the subjects before CQI and 24.0% after CQI (p<0.05). The overall incidence of peritonitis reduced from once every 40.1 patient months before the CQI to once every 70.8 patient months after CQI (p<0.05). The incidence of Gram-positive bacteria peritonitis reduced from once every 96.9 patients per month before CQI to once every 209.1 patient months after CQI (p<0.05), whereas the incidence of Gram-negative bacteria peritonitis reduced from once every 234.2 patient months before CQI to once every 292.8 patient months after CQI.
  
  
  CONCLUSIONS
  CQI can effectively reduce the occurrence of PD-related peritonitis.
