Acute Kidney Injury in COVID-19 Pneumonia Patients Admitted to the Intensive Care Unit

Abstract

This retrospective study was conducted at the Izmir Tepecik Training and Research Hospital from January 2020 to December 2021. It aimed to determine acute kidney injury (AKI) frequency and associated factors in critically ill COVID-19 patients. Out of 177 patients, 49.7% developed AKI, with an average onset of 7.63 days. AKI stages varied, and progression occurred in 27 patients within 48 hours. ICU and hospital mortality rates were significantly higher in AKI patients (86.4% and 92%, respectively) compared to non-AKI patients (19.1% and 22.5%). The study highlights age, sequential organ failure assessment (SOFA) score, and nephrotoxic agent presence as significant factors influencing AKI development in COVID-19 patients.
