Epidemiology of haemodialysis patients and haemodialysis performance in Nauru.

Abstract

There is limited literature on haemodialysis in island countries in the Central Pacific. The primary aim of this study was to report on the epidemiology of haemodialysis patients and haemodialysis performance in Nauru. We obtained registry data from the haemodialysis unit in Nauru to calculate the incidence rate, prevalence, and survival probability of haemodialysis patients in Nauru. We also reviewed medical records from January 2015 to February 2017 to evaluate the haemodialysis performance in Nauru. In total, 177 patients received long-term haemodialysis in the Nauru dialysis unit from 1987 to 2017. The 1-year, 2-year, and 5-year survival probabilities during the 30-year study period were 76.5%, 58.3% and 25.9%, respectively. From 2011 to 2014, the incidence rate and prevalence of treated end-stage renal disease in Nauru were significantly higher than Australia. From 2015 to 2017, there were 36 patients with a median age of 55 years who received long-term haemodialysis. Of these, 25 patients (69.4%) had diabetes. The median haemoglobin, serum albumin, and urea reduction ratio were 9.6 mg/dL, 35 g/L, and 64.7%, respectively. Multivariate analysis showed that lower serum albumin and lower urea reduction ratio were associated with mortality. To our knowledge, this is the first study to report the haemodialysis status in Nauru. The epidemiology of haemodialysis patients in Nauru is unique in the Central Pacific. Improvement of primary health care in disease detection and prevention of progression should be considered to decrease the need for dialysis and optimise the care of haemodialysis patients in Nauru.
