Analysis of the influencing factors on the quality of life of the elderly hemodialysis patients

Objective The present study aims to identify factors affecting quality of life in elderly patients undergoing maintenance hemodialysis (MHD). Methods A total of 656 patients undergoing MHD in 10 hospitals in Beijing were enrolled. Patients aged >= 65 years were allocated to the elderly group; patients aged < 65 years were allocated to the non-elderly group. The patients' quality of life was described based on their general situation, physiological function, cognitive status (which was assessed using the Basic Montreal Cognitive Assessment), and answers to the Kidney Disease Quality of Life((TM)) questionnaire. Results Statistically significant differences between the two groups (P < 0.05) were observed in gender ratio, marital status, medical type, and sleep duration. Patients who did not live alone, had a higher average annual income, and had a longer sleep duration also had a higher cognitive ability. Total protein concentration and a depressive state were positive predictors of renal disease burden. Conclusion Age, underlying disease, and complications can affect the quality of life of patients on MHD.
