Health-related quality of life and health utility of Chinese patients undergoing nocturnal home haemodialysis in comparison with other modes of dialysis

Background: To compare the health-related quality of life (HRQOL) and health utility of Chinese patients with end-stage renal disease (ESRD) undergoing nocturnal home haemodialysis (Home HD) against those patients undergoing other modes of dialysis. Methods: Chinese ESRD patients undergoing Home HD were recruited in renal specialist outpatient clinics at three public hospitals in Hong Kong. SF-12 Health Survey (SF-12) was used to measure HRQOL and generate the SF-6D heath utility score. Mean scores of SF-12 domains, physical and mental component summary and SF-6D health utility of 41 patients undergoing Home HD were compared with available scores of patients receiving other forms of dialysis, namely, peritoneal dialysis (PD) (n = 103), hospital incentre HD (n = 135) or community in-centre HD (n = 118). Adjusted linear regression models were used to examine the impact of mode of dialysis on the HRQOL and health utility scores, accounting for the sociodemographic and clinical characteristics. Results: ESRD patients undergoing PD and community in-centre HD had better health utility, physical and mental component summary scores than the hospital in-centre HD. Adjusted analysis showed that hospital in-centre HD reported worse physical component summary and health utility scores when compared with PD and community in-centre HD. Conclusion: HRQOL and health utility scores of patients undergoing Home HD were similar to those undergoing PD and community in-centre HD. Better physical aspects of HRQOL and health utility was observed in PD and community-based HD than hospital in-centre HD, providing evidence for the increase in capacity of non-hospital-based HD, which provided flexibility as well as patient centredness and empowerment in Hong Kong.
