End-stage renal disease in the Asian-Pacific region

Information on end-stage renal disease (ESRD) is important in assisting health care providers in planning renal replacement therapy. A questionnaire was sent to various countries in the Asian Pacific region and 10 countries responded. Data from Australia and New Zealand was obtained from their registry report. The questionnaire requested information on incidence, prevalence, transplantation rate, demographic data, causes of ESRD, causes of death, and mortality rates for the years 1998 to 2000. All the countries surveyed had national registries and there was a greater than 90% response rate in 7 of 12 countries. The incidence and prevalence rates of ESRD were linked to funding of dialysis, with higher reported rates in countries where dialysis was totally or heavily subsidized by the government. There was an increase in both incidence and prevalence rates between 1998 and 2000, with the mean annual percentage increase of 1.2% to 14.1% for incidence and 4.2% to 17.3% for prevalence. Diabetic nephropathy was the most common cause of ESRD in 9 of the 12 countries surveyed and 6 of the 12 countries had greater than 35% of their dialysis patients age 60 years and older. Peritoneal dialysis (PD) use varied between 3.9% to 81% of the dialysis population and reflected the health care policies of the individual countries. The transplantation rate was influenced by socioeconomic, religious, and cultural attitudes and varied between 3.1 per million population (pmp) to 32 pmp with the percentage of cadaveric transplants ranging between 0% of 85% of total transplants. Cardiovascular mortality remained the most common cause of death in the ESRD patients. Collaboration between the various national registries in the form of specific international studies may yield useful information of ESRD patients in the Asian-Pacific region.
