MO719PERITONEAL DIALYSIS IN ELDERLY PATIENTS

Abstract

Abstract Background and Aims Peritoneal Dialysis (PD) is now often being initiated in older patients. The benefits of this modality of dialysis have been well demonstrated in the literature. The aim of our study was to analyse the epidemiological and clinical profile of the elderly patients and to determine predictive factors of mortality Method It was a retrospective study including 51 case defined as patients ≥65-year-old, treated by PD in the Internal Medicine Department of the Charles Nicolle hospital during the period between 1986 and 2020. Results Fifty one patients were enrolled in the study. Their mean age was 71,6 ± 5,4 years [65 - 86]. There were 32 men (62, 7%) and 19 women (37,2%) . The method of initiation was the PD in 53, 84%. Diabetic and vascular nephropathy was the first cause of End-Stage Renal Disease in 56% and 19,6%. The mean Charlson score was 5,5 ± 1,4 [3-9]. The mean age when using PD was 70.8 ± 6 years [54-86]. Autonomous and active patients were detected in 29.4%. Diabetes mellitus, hypertension and coronary artery disease was observed in 58,8%, 29,4% and 15.7% of patients. In our study, 82.35% started on automated PD (APD) and 17,6% on continuous ambulatory PD (CAPD). The rate of mortality was 53%. Switching modality from PD to hemodialysis occurred in 29,4% of cases. A univariate logistic regression identified a coronary artery disease as significantly associated with increased mortality (HR=2,1 [1-2,1, IC 95%](p=0.035)). Conclusion Elderly patients on dialysis face many issues but can have continued success with PD when they have adequate care and support. The control of the morbidities such as coronary artery disease is important to decrease the rate of mortality in patients using this modality of dialysis.
