How to have--a successful peritoneal dialysis program.

The proportion of end-stage renal disease patients on continuous ambulatory peritoneal dialysis (CAPD) has increased by twofold in Hong Kong over last two decades, accounting for 80% of the entire dialysis population. Our encouraging outcome results--a 2-year actuarial patient survival of 83%, and a 2-year technique survival of 72.8%--further testify to the success of CAPD in our territory. A relatively constant successful outcome has been achieved despite an increasing prevalence of diabetes mellitus and an aging population. The present review postulates the reasons behind our success. Apart from reimbursement policy, technique-related factors, and center effects, inherent patient factors--including baseline survival advantage of Chinese patients, genetic difference, cardiovascular risk factors, and possibly lower dialysis volume requirement and compliance--are thought to be contributory. As for the future, more efforts are needed to further improve the technique survival rate and the nutritional status, psychosocial well-being, and rehabilitation of CAPD patients. Judicious assessment of peritoneal dialysis adequacy and preservation of residual renal function should be constantly exercised to tailor treatment to the needs of Chinese CAPD patients.
