Abstract: Objective  This study investigated the comfort status of patients with maintenance peritoneal dialysis (PD) and analyzed its influence factors.  Methods  Convenience sampling was used to select patients with PD who were followed up in the First Affiliated Hospital of Sun Yat-sen University from January 2019 to June 2022. The comfort status of PD patients was evaluated by the self-made comfort scale of PD. Demographic data and clinical data were also collected.  Results  A total of 212 maintenance PD patients were included in this study. Their mean age was 46.5±13.2 years, 56.1% were male, the median duration of PD was 28.6 (10.3,64.0) months, and glomerulonephritis was the primary renal disease in 63.7% of the patients. The total score of comfort scale was 93.2±11.2 points, and the mean score of each dimension item showed that the mean score of physiological dimension was the lowest (3.3±0.5 points), followed by the mean score of psychological dimension and social dimension items (3.5±0.5 points and 3.5±0.5 points respectively); the mean score of environmental dimension item was higher (3.8±0.4 points). Multivariate linear regression showed that older age (β=0.136, P=0.027) and higher level of total creatinine clearance index (β=0.160, P=0.046) were the independent protective factors for the total score of comfort scale.  Conclusions  Clinical nurses should improve the physical discomfort of maintenance PD patients, strengthen psychological nursing and social support in the process of nursing, and pay more attention to the younger patients and patients with lower total creatinine clearance index.
