Comparison of Outcomes and Quality of Life between Hemodialysis and Peritoneal Dialysis Patients in Indian ESRD Population

Abstract

Background: Hemodialysis (HD) and peritoneal dialysis (PD) are important renal replacement treatments in end stage renal disease (ESRD). There is paucity of data comparing outcomes and quality of life (QOL) between the two modalities in Indian scenario.

Materials and methods: We followed 60 End stage renal disease patients (30 CAPD and 30 Maintenance hemodialysis) for a period of one year. Patients were analysed and compared for complications, physical quality of life and psychological well being with a two part self reported questionnaire at baseline and subsequently at six and twelve months. For the physical component appropriate sections of the McMaster Health Index Questionnaire (MHIQ) and for psychological component Psychological General Well-Being Index (PGWB) developed by Dupey was applied.

Results: The number of males and females in both groups were comparable (p-value > 0.05).The prevalence of diabetes mellitus, coronary artery disease, obesity and ischaemic heart disease was comparable in both groups (p-value>0.05). Significantly higher mortality was observed in patients undergoing HD (20% vs 0 %, p-value <0.05) at the end of study. At the end of study, 16.6% of patients undergoing HD were found to be anti HCV positive as compared to 3.33% in CAPD. Six episodes of CAPD peritonitis were observed (0.2 episodes per catheter year). Significantly higher number of CAPD patients had negative responses between 2-4 at baseline and subsequently on follow ups in Part A of QOL questionnaire(86.7 vs 23.3 % at baseline, 80 vs 26.7% at 6 months, 80 vs16.7 % at 12 months; p <0.05 ). Mean score in Part B of questionnaire was significantly higher in CAPD patients at baseline and at all follow ups (66.7±11 vs 50.1±17 at baseline, 66.7±12.1 vs 53.32±16.3 at 6 months, 65.3±9.5 vs 48.8±16.7 at 12 months , p <0.05) .

Conclusion: CAPD patients have significantly better quality of life in physical as well as psychological aspects and have significantly lower mortality when compared with hemodialysis patients.
