Mortality rates associated with acute kidney injury (AKI) hospitalization are high, with 28% of patients dying within 1 year, according to a study published in the Clinical Journal of the American Society of Nephrology. Ryann Sohaney, DO, and colleagues studied patients hospitalized from Oct. 1, 2008 to Sept. 31, 2017. In-hospital and 1-year mortality trends were examined for those with and without AKI. Nearly 1.7 million patients and approximately 2.7 million hospitalizations were identified. Among those with AKI, 6% died in the hospital and 28% died within 1 year. Among non-AKI hospitalizations, in-hospital and 1-year mortality rates were 0.8% and 14.0%, respectively. A slight decline in crude in-hospital AKI-associated mortality was seen (HR, 0.98 per year; 95% CI, 0.98-0.99); after adjusting for demographics, comorbid conditions, and acute hospitalization characteristics, the decline was attenuated (adjusted HR, 0.99; 95% CI, 0.99-1.00).
