SAT-130 5-YEARS MORTALITY ANALYSIS IN HAEMODIALYSIS PATIENTS IN A SINGLE CENTRE IN DUBAI

Abstract

Objective The purpose of this study is to determine the mortality among patients on haemodialysis. This observational cohort study was conducted at Dubai Hospital during the period between January-2012 till Dec-2016. All adults' patients with ESRD on haemodialysis irrespective of their age, gender and duration of dialysis were enrolled. Mortality among these patients along with certain information like age at the time of death, gender, cause of ESRD, co-morbidities and serology report were collected. Out of a total of 411 patients, 112 (27.3%) patients died during the study period, 56% were male and their median age at the time of initiation of dialysis and at time of death was 59.38±13.5 and 63.8±13.6 respectively. 13 patients suffer early mortality i.e. died within 365 days of initiation of dialysis. Diabetes mellitus was the most common cause of ESRD (73%) among the deceased populations, whereas Hypertension was the most prevalent comorbidity in our study group. Low levels of haemoglobin (46%), albumin (54%) and parathyroid hormone (72%), whereas high ferritin (63%) and abnormal phosphorus (61.6%) were predominant biochemical parameters in the deceased patients. The leading cause of death was cardiovascular in 48 patients (42.85%) followed by infection /sepsis (21patients, 18.75%), unknown causes/sudden death (including sudden death at home) in 18 patients (16.07%) and cerebrovascular events in 7 patients (6.2%). Other causes include gastrointestinal haemorrhage, liver disease and pulmonary embolism. Generally, older age group, diabetes mellitus, prolonged duration on dialysis and cardiac diseases were the common causes of mortality in our study population.
