title: Peritoneal Dialysis Registry With 2012 Survey Report.
abstract: Since 2009, the peritoneal dialysis (PD) registry survey 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 report, the current status of PD patients is presented on the basis of the results of the survey conducted at the end of 2012. The subjects were PD patients who lived in Japan and participated in the 2012 survey. Descriptive analysis of various items was performed, which included 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 rates of peritonitis and catheter exit-site infection. From the results of the facility survey in 2012, the number of PD patients was 9514, a decrease of 128 from 2011. Among the entire dialysis patient population, 3.1% were PD patients, a decrease of 0.1%. Among the studied patients, 347 had a peritoneal catheter and underwent peritoneal lavage, 175 were started on PD in 2012 but introduced to other blood purification methods in the same year, and 1932 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 PD vintage: <1 year, 4.8%; 1 to <2 years, 9.2%; 2 to <4 years, 16.3%; 4 to <8 years, 32.0%; and ≥8 years, 47.5%. The percentage of PD patients who completely manually exchanged the dialysate was 29.8%. The percentages of PD patients who used a double-bag exchange system with ultraviolet-light irradiation and those who used the same system but with a sterile connecting device were 54.7 and 13.9%, respectively. The percentage of patients on PD for <1 year using an APD machine was 43.4%, and it decreased with a PD vintage of ≥2 years. The mean rate of peritonitis was 0.22 per patient per year. The mean rate of catheter exit-site infections was 0.36 per patient per year.
