Abstract：Tostudythetunnelinfectionrate,exit-siteinfectionratedifferencebetweenperitonealdialysispa-tients( PD)≥4 years and patients who died or changed from peritoneal dialysis to hemodialysis patients in 4 years. Methods:Collection 1996-2012 medical records of the PD patient's outcomes and infection( prospective since 1993). Patients were di-vided into two groups:continuous ambulatory peritoneal dialysis( CAPD ),continuous cycle peritoneal dialysis( CCPD )≥4 years patients(n=43,referred to as≥4 years group),conduct CAPD,CCPD less than 4 years patients(died or changed to he-modialysis,n=213,referred to ﹤4 years group). Observed the export infection prevalence,tunnel infection prevalence due to a variety of pathogenic microorganisms cause of Peritoneal dialysis patients were during. Results:The incidence of exit site infec-tion in ﹤4 years group and≥4 year group was1. 2 times/year and 0. 7 times/year(P﹤0. 000 1),respectively,difference is partly due to Staphylococcus aureus(0. 45 times/year and 0. 3 times/year,P﹤0. 001),and other Gram-positive bacteria (0. 28 times/year and 0. 10 times/year,P﹤0. 001),the tunnel infection rates of two group are same(0. 2 times/year). Con-clusion:Although the infection rates of ≥4 years group is lower,staph infections accounted for a higher proportion,Need for improved infection prevention techniques to improve dialysis patient survival,Improved dialysis techniques are needed in order to prevent infection and improve survival.
