Comparative Study
Comparison of prognostic value of two kinds of severity scoring systems for hospital mortality prediction of elderly patients with acute kidney injury.
Outcome prediction is important in clinical practice. Despite significant improvements in therapeutics, the mortality associated with acute kidney injury (AKI) in elderly patients remains high. Several severity scoring systems have been used in hospital mortality prediction of patients, but little is known of their significance in elderly patients with AKI. The aim of this study is to evaluate the ability of version II of Acute Physiology and Chronic Health Evaluation (APACHE II) and Acute Tubular Necrosis Individual Severity Index (ATN-ISI) on predicting the hospital mortality of elderly patients with AKI. ⋯ APACHE II and ATN-ISI scoring systems can predict the hospital mortality of elderly AKI patients. However, APACHE II performs better than ATN-ISI.
