Incidence and Risk Factors for Acute Kidney Injury and its effect on Mortality in Patients Hospitalized from Covid-19
2020
Abstract Objective To determine the incidence of and risk-factors for development of acute kidney injury (AKI) and investigate the association between AKI and mortality in patients hospitalized with Covid-19. Patients and Methods This retrospective case series includes the first 370 patients consecutively hospitalized with confirmed Covid-19 illness between March 10, 2020 and May 13, 2020, at a 242-bed teaching hospital. To determine independent association between demographic factors, comorbidities and AKI incidence, multivariable-logistic regression models were used to estimate odds ratios adjusted for clinical covariates. Results Median age of patients was 71 (59–82) years and 44.3% were female. Patients with AKI were significantly older with a higher comorbidity-burden and mortality-rate (58.1% vs 19.6%, p Conclusion AKI is a common complication among hospitalized Covid-19 patients. We found significantly higher odds of AKI with increasing age, among hyperlipidemics and patients with chronic kidney disease and among African-Americans. We demonstrate an independent association between AKI and mortality with increasingly higher odds of mortality from progressively worsening renal failure in hospitalized Covid-19 patients.
