Summary
Continuous ambulatory peritoneal dialysis (CAPD) shows significant dropout rates in Brazil. Survival rates were lower than expected, especially for vulnerable patient groups, indicating challenges in its widespread adoption.
Area of Science:
- Nephrology
- Public Health
- Epidemiology
Background:
- Limited data exists on Continuous Ambulatory Peritoneal Dialysis (CAPD) performance in developing nations.
- This study addresses the scarcity of research by examining CAPD in Rio Grande do Sul (RS), Brazil's southernmost state.
Purpose of the Study:
- To analyze the experience and outcomes of CAPD in Rio Grande do Sul, Brazil.
- To compare CAPD with hemodialysis and kidney transplantation in a Brazilian urban setting.
Main Methods:
- A retrospective cohort study of 1316 CAPD patients in RS using Health Secretary records.
- A comparative cohort study in Porto Alegre (1993) of patients initiating renal replacement therapy (CAPD, hemodialysis, transplant).
Main Results:
- CAPD patient numbers in RS initially grew but then plateaued.
- One-year and five-year survival rates were 78.6% and 40.7%, respectively. Technique survival was 57.4% (1 year) and 10.1% (5 years).
- In Porto Alegre, CAPD patients had better adjusted survival than hemodialysis patients but represented a small fraction of renal replacement therapy users, with high dropout rates.
Conclusions:
- CAPD is not a widely adopted renal therapy in Rio Grande do Sul, Brazil.
- High dropout rates and specific patient vulnerabilities impact CAPD's long-term success.
- Further research is needed to understand and mitigate barriers to CAPD utilization and improve patient outcomes in this region.
