Application of KDQOL-SFTM 1.3 version in evaluating quality of life of maintenance hemodialysis patients in multiple centers

Objective To understand the quality of life (QOL) and its influencing factors in maintenance hemodialysis patients (hemodialysis maintenance, MHD), and to provide theoretical basis for improving QOL of patients. Methods A cross-sectional study was conducted in the blood purification centre in 8 hospitals of Hefei, and patients clinical data were collected. KDQOL-SF self-administered questionnaire was applied to assess the health related quality of life (HRQL) of patients and to analyze the factors influencing the QOL. Results The QOL of MHD patients in Hefei City was better compared with previous similar research results. Generally speaking, gender (male), education degree and household income were positive correlated with QOL scores (P＜0.05), and the scores of primary disease of patients with diabetic nephropathy or drugs were lower (P＜0.05) in physiological component summary (PCS), mental component summary (MCS), SF-36 and KDTA. Charlson comorbidity index (CCI) was negatively correlated with the MCS scores, PCS scores and SF scores (P＜0.05), and patients' occupational and medical insurance had impacts on MCS and KDTA score (P＜0.05). Conclusions The QOL of MHD patients are affected by many factors, and the CCI and cultural level are possible independent influencing factors. In addition, gender, household income per capita, primary disease, occupation, medical insurance also have certain influence.
