Peritoneal Dialysis Registry With 2013 Survey Report

Area of Science:

• Nephrology
• Public Health
• Epidemiology

Background:

• The Japanese Society for Dialysis Therapy conducts an annual nationwide survey, including a peritoneal dialysis (PD) registry since 2009.
• This study analyzes the 2013 survey data to report the current status of PD patients in Japan.

Purpose of the Study:

• To describe the current status of peritoneal dialysis (PD) patients in Japan based on the 2013 survey.
• To analyze trends in combined PD and other dialysis methods, dialysate exchange techniques, and infection incidences.

Main Methods:

• Descriptive analysis of data from the 2013 Japanese nationwide PD survey.
• Inclusion of patients who underwent PD, combined PD with hemodialysis (HD) or hemodiafiltration (HDF), and those using automated peritoneal dialysis (APD) machines.

Main Results:

• In 2013, there were 9392 PD patients, a 0.1% decrease from 2012, representing 3.0% of all dialysis patients.
• The use of combined PD with HD/HDF increased with the duration of PD treatment, reaching 57.5% for patients on PD for ≥10 years.
• The mean incidence of peritonitis was 0.22 per patient-year, and catheter exit-site infection was 0.34 per patient-year.

Conclusions:

• The prevalence of PD in Japan saw a slight decrease in 2013.
• Combined PD and other dialysis modalities are increasingly utilized, particularly in long-term PD patients.
• Standardized data collection provides valuable insights into PD patient demographics, treatment modalities, and infection rates.
