The Effect of Treatment on Short-Term Outcomes in Elderly Patients with Acute Kidney Injury

Abstract

BACKGROUND:Elderly population (≥ 65) are more prone to develop acute kidney injury (AKI) compared to younger, also elderly with AKI have an increased requirement for dialysis treatment and an elevated risk of short-term and long-term mortality.AIM:The objectives of this study were to examine the effect of treatment of short-term outcomes and mortality in elderly patients with AKI.MATERIAL AND METHODS:Seventy elderly AKI patients, that filled one of the criteria of AKI definition and had hospitalization over 24 hours, were enrolled in the study.RESULTS:The median age of patients was 74.28 ± 6.64, with mean CCI (Charlson Comorbidity Index) score of 6.94 ± 1.94. The majority of patients (70%) were classified at stage 3 of AKIN, 20% of patients were classified at stage 2 and 10% at stage 1. In the groups of patients with death outcome, the chronic cardiomyopathy was more frequently present (p = 0.034). Regarding treatment, 58.6% of the AKI patients underwent hemodialysis while 41.4% received conservative treatment. Mortality rate was 52.8%, out of which 28.6% was in-hospital mortality, while in 24.3% of patients death occurred in the follow-up period of 90 days.CONCLUSION:In our study, short- term survival is not related to different treatment options. Applied treatment in elderly patients with AKI should be assessed by measuring the long term outcome.
