Abstract Background and Aims The prevalence of CKD increases with age and more elderly patients are on maintenance dialysis as advanced age is no longer an impediment. The selection of dialysis modality can be difficult for the simultaneous benefit and burden of individual modality on top of the complexity of co-morbidity and quality of life. To study the survival outcomes based on dialysis modality in geriatric ESRD patients Method The cohort of geriatric patients (aged > 65 years) with ESRD who were referred to our pre-dialysis clinic from 1st January 2016 to 31st December 2018 and started on maintenance dialysis were identified via the hospital information system. Demographics, co-morbidities, dialysis modalities and clinical outcome in terms of survival were obtained from the hospital electronic medical record. Glomerular filtration rates (eGFR) were calculated using the CKD-EPI formula in mls/min/1.73m2. The statistical analysis was done using SPSS version 23. Results A total of 145 geriatric ESRD patients were initiated on chronic dialysis. The cohort was predominated by male with 77 patients (53.1%). The mean age was 72.5±5.2 years. Majority had multiple comorbidities with 95% having hypertension, 82.8% with diabetes, 65.5% and 32.8% having dyslipidemia and ischemic heart disease, respectively. The mean eGFR at point of referral and dialysis initiation were 12.5±4.9 mls/min/1.73m2 and 6.57±2.33 mls/min/1.73m2 respectively. Mean duration to initiate dialysis from first review was 6.7±5.8 months. Majority opted for hemodialysis (HD) with 106 patients (73.1%). 74% patients in the HD cohort initiated dialysis via a catheter and remainder with an arteriovenous fistula (AVF). 39 patients (27.1%) opted for peritoneal dialysis (PD) and all were initiated via tenckhoff catheter. Mean eGFR at dialysis initiation were 6.44±2.47 (HD) and 6.9±1.9(PD) respectively. At 6 months, all PD patients survived and 18.2% of HD patients died with statistically significance difference at p=0.003. No survival predictors were identified. Conclusion PD modality has advantage in survival outcome in geriatric ESRD patients.
