title: Peritoneal Dialysis Registry With 2013 Survey Report.
abstract: Since 2009, the peritoneal dialysis (PD) registry has been carried out as part of the annual nationwide survey conducted by the Statistical Survey Committee of the Japanese Society for Dialysis Therapy with the cooperation of the Japanese Society for Peritoneal Dialysis. In this study, the current status of PD patients is reported on the basis of the results of the survey conducted at the end of 2013. The subjects were PD patients who lived in Japan and participated in the 2013 survey. Descriptive analysis was performed for various items including the current status of the combined use of PD and another dialysis method such as hemodialysis (HD) or hemodiafiltration (HDF), the method of exchanging dialysate, the use of an automated peritoneal dialysis (APD) machine, and the incidences of peritonitis and catheter exit-site infection. From the results of the facility survey in 2013, the number of PD patients was 9392, a decrease of 122 from that in 2012. Among the entire dialysis patient population, 3.0% were PD patients, a decrease of 0.1%. Among the studied patients, 292 had a peritoneal catheter and underwent peritoneal lavage, 174 were started on PD in 2013 but introduced to other blood purification methods in 2013, and 1920 underwent both PD and another dialysis method such as HD or HDF. The percentage of patients who underwent PD and another dialysis method increased with the number of years on PD: <1 year, 3.5%; 1 to < 2 years, 8.4%; 2 to < 4 years, 15.3%; 4 to < 6 years, 27.1%; 6 to < 8 years, 39.3%; 8 to < 10 years, 47.1%; and ≥ 10 years, 57.5%. The percentage of PD patients for whom the dialysate was completely manually exchanged was 31.6%, whereas the percentages of PD patients who used a bag-exchange device based on ultraviolet-light irradiation and that based on thermal sterile joint systems were 52.1 and 14.9%, respectively. The mean incidence of peritonitis was 0.22 per patient per year (once per 54.5 patients per month). The mean incidence of catheter exit-site infection was 0.34 per patient per year (once per 35.3 patients per month).
