Abstract

Background/aim: The aim of this study was to evaluate the clinical outcomes and identify the predictors of mortality in peritoneal dialysis patients.

Materials and methods: Medical records of all incident peritoneal dialysis (PD) patients followed up between January 2011 and May 2019 were reviewed retrospectively. All patients were followed up until death, renal transplantation, transfer to haemodialysis or the end of the study.

Results: A total of 242 patients were included in the study. The incidence of peritonitis was 0.18 (ranging from 0 to 14.9) episodes per patient year. Death occurred in 28% (n: 68) of cases. Age, diabetes mellitus, malignancy and refractory heart failure were independent risk factors for all-cause mortality according to multivariate analysis. The presence of comorbid disease and diabetes mellitus and patients aged > 65 years were associated with increased risk of mortality and decreased patient survival. Peritonitis history was associated with increased risk of mortality. Between peritonitis and peritonitis-free group, there was no significant difference in Kaplan-Meier curves in terms of patient survival.

Conclusion: This is the first study to define 9-year mortality predictors in PD patients in our centre. Although peritonitis is the most feared complication of PD, our study showed that peritonitis did not reduce patient survival.

Keywords: Peritoneal dialysis; mortality; patient survival; peritonitis; technique survival.
