Prognosis of in hospital nonagenarians with acute kidney injury

There has been little in the way of study of nonagenarians with acute kidney injury (AKI, defined in lines with KDIGO guidelines), but the rise in their life expectancy makes further study of this population necessary. The aim of this study is to assess mortality in nonagenarians with AKI during hospitalization. In this retrospective study, patients with AKI during hospitalization between 2013-2014 were included. At baseline, epidemiological variables, comorbidities and treatments were collected. Analytics and mortality were studied during hospitalisation. Univariate analysis was carried out to evaluate mortality-associated variables. A logistic regres-sion analysis was carried out to demonstrate independent predictors for mortality. Two hundred and sixty-four nonagenarian patients were included. Mean age was 93±3 years, 73 (27.7?%) of whom were men. During hospitalization, 79 patients (29.9?%) died. Comorbidities related to mortality were history of heart failure (p?=?0.018), diastolic dysfunction (p?
