Effects of Peritoneal Dialysis on Clinical Factors and Functional Performance.

Background: We investigated the longitudinal trend of functional performance in peritoneal dialysis (PD) patients over 1 year after PD commencement and its related clinical parameters. Methods: One hundred and ninety-six PD patients were enrolled in this study. Karnofsky Performance Status Scale(KPSS) scores were used to assess functional performance. Patients were stratified into 3 groups according to the changes in KPSS from baseline to 1 year. A logistic regression analysis was performed to examine the associations of clinical parameters with KPSS changes. Results: Patients with KPSS declined showed older age and higher serum albumin concentration reduction within 1 year than those in KPSS improved and stable changes. Age was the significant risk factor for KPSS decline, while male and diabetes were significantly associated with non-declined KPSS by multivariable logistic regression analysis. Conclusion: The main determinants of KPSS trend were age, sex, and diabetes in new PD patients.
