ABSTRACT
Objective:
to analyze the incidence, risk factors and survival of critically-ill patients with acute kidney injury.
Method:
a concurrent cohort study, conducted with 126 participants between May and September 2019 in a public Intensive Care Unit of the state of Acre. The Kaplan-Meier method was used to estimate the probability of death (log-rank 95% test) and the Cox regression model was employed to determine the prognostic factors of death.
Results:
the incidence of acute kidney injury was 37.3 per 1,000 individuals admitted to the intensive Care Unit. Disease recovery was the outcome in 36.7% of the patients, and 42.9% evolved to death. The conditional probability of death was higher in the female gender and in those who did not use mechanical ventilation, with glomerular filtration rate at admission < 60 ml/min/1.73 m2 and sepsis diagnosis. Regardless of the acute kidney injury diagnosis, the risk factors associated with death in the population of critically-ill patients were serum creatinine above 1.2 mg/dl at admission and glomerular filtration rate < 60 ml/min/1.73 m2 at admission.
Conclusion:
in this population, survival is aggravated by gender dimorphism and by the reduction of the glomerular filtration rate.
