The quality of life and associated factors in patients on maintenance hemodialysis - a multicenter study in Shanxi province

Objectives: To assess the quality of life (QOL) and factors affecting QOL in hemodialysis patients so as to improve QOL of dialysis patients and provide the basis for better clinical care.Methods: A retrospective study was performed to assess the QOL and factors affecting QOL in hemodialysis patients. We recruited 125 patients who had been receiving hemodialysis for at least 2years in the dialysis units of nine hospitals in Shanxi Province, China, and conducted a multi-center questionnaire survey between 1 May 2015 and 1 July 2016. We investigated the patients' general condition and clinical data and used the Short Form-36 (SF-36) scale to measure QOL in these patients.Results: The overall SF-36 score was 107.5514.50 in patients who had received hemodialysis for more than 2years. Age (p<.05, F=4.972) and gender (p<.01, t=3.993) significantly affected the overall QOL score in these patients. Education level was also an influencing factor (p<.05, Z=-0.838), especially on the mental health of these patients. In addition, residual urine volume (p<.05, Z=-2.465) and diabetic nephropathy (p<.05, Z=-2.062) were important factors that affected the physical strength and QOL score in these patients. However, sources of medical expenses, marital status and different methods of dialysis, had no effect on the QOL score.Conclusion: The overall score of QOL in patients who have received maintenance hemodialysis for more than 2years is higher in Shanxi Province than that in other provinces of China. Only a few factors influenced the QOL of these patients.
