Gacouin A, et al. - In this prospective observational cohort study conducted at a 21-bed polyvalent ICU in a university hospital, researchers investigated if at-risk drinking was independently related to acute kidney injury in the ICU and at ICU discharge. Adult patients (n=1,107) who sought admission during a 30-month period, with an ICU stay of greater than or equal to 3 days and in whom alcohol intake could be evaluated, were included. Compared to non–at-risk drinkers, a significantly higher proportion of at-risk drinkers had stages 2–3 acute kidney injury at admission to the ICU. In critically ill patients, a link was found between chronic and current alcohol misuse and kidney dysfunction. Acute kidney injury may be prevented via systematic and accurate identification of patients with alcohol misuse.
