Acute kidney injury in the elderly hospitalized patients

AbstractObjective: We aimed to evaluate acute kidney injury (AKI), occurrence of recovery and risk factors associated with permanent kidney injury and mortality in the elderly individuals. Design: Evidence for this study was obtained from retrospective cohort study from our center. Patients: A total of 193 patients (>65 years, mean age: 79.99 ± 6.93) with acute kidney injury were enrolled in this study between 2011 and 2012. Patients with kidney failure or renal replacement therapy (RRT) history at admission were excluded. Intervention: Main outcome measurements: serum creatinine (SCr), estimated GFR (with CKD-Epi) and complete blood counts were evaluated at baseline and daily basis thereafter. The AKI was defined based on Kidney Disease Improving Global Outcomes (KDIGO) classification. Results: Among 193 patients, 43 (22%) patients required RRT. Mortality rate was 18% (n = 36) SCr levels were restored within 9.9 ± 6.7days on average (8–39 days). Sixteen patients (12.7%) required RRT after discharge. The ...
