CAPD in southern Brazil: an epidemiological study.
There are many studies on the performance of continuous ambulatory peritoneal dialysis (CAPD) in developed countries, but studies in the third world are scarce. The aim of this study is to analyze CAPD experience in the southernmost state of Brazil (Rio Grande do Sul, RS). Records were obtained from the Health Secretary of RS to assemble a cohort of all patients treated with CAPD. Another cohort study followed all patients initiating treatment for uremia in 1993 in the state capital, Porto Alegre, and compared CAPD, hemodialysis, and transplanted patients. In RS, 1316 patients (50.4% male, mean age 45.9 years) were treated in 40 CAPD programs. Despite the initial growth of the CAPD population, it subsequently leveled off. Survival was 78.6% and 40.7% in years 1 and 5, being worse for initial patients of each program, infants, and elders. Technique survival was 57.4% and 10.1% at years 1 and 5. Patients interrupting treatment for any reason had a higher chance of dropout. In Porto Alegre, 294 patients started dialysis during 1993; 21 performed CAPD, 44 had a transplant, and the others were hemodialyzed. Children were treated mostly by CAPD. CAPD patients had less diabetes and ischemic heart disease and received more transplants. Their adjusted actuarial survival (100% year 1; 67% year 3) was no different than hemodialysis. CAPD is not a popular form of renal therapy in RS, and dropout rates are significant.
