Abstract: Objective To analyze the factors relating to the quality of life in peritoneal dialysis (PD) patients treated in Peking University Third Hospital. Methods SF-36TM survival quality assessment scale was used in this cross-sectional study. Quality of life was assessed and compared among different patient groups. Dialysis adequacy, Charlson comorbidity index (CCI) and biochemical parameters were analyzed to assess their relevance to quality of life in PD patients. Results In the 93 PD patients, physical components score (PCS) was 59.4 (43.4～74.8), and mental components score (MCS) was 68.2 (51.9～78.8). Patients with different gender, marriage situation, medical reimbursement ratio, live condition, and educational level had no significant differences in quality of life, while patients who live on themselves and those who must rely on others were different in PCS and MCS. Dialysis condition parameters had no relevance to quality of life in PD patients. CCI and serum albumin were the independent risk factors for quality of life in PD patients. Conclusion CCI and serum albumin were the independent risk factors for quality of life in PD patients. These results suggest that improvement of self-management skills and treatment of comorbidities may have a positive effect on quality of life in PD patients.
