Risk factors for depression and anxiety in survivors of acute respiratory distress syndrome

Abstract Objective Depression and anxiety are common morbidities of critical illness. We assessed risk factors of depression and anxiety in Acute Respiratory Distress Syndrome (ARDS) survivors at 1 and 2 years post-hospital discharge. Method Risk factors for depression and anxiety at 1 and 2 years were assessed using stepwise multiple regression analyses, with and without 1-year outcomes. Results ARDS survivors had depression (16% and 23%) and anxiety (24% and 23%) at 1 and 2 years, respectively. Predictors of depression at 1 year were alcohol dependence, female gender and younger age ( P =.006). Predictors of anxiety were ratio of arterial oxygen tension to inspired oxygen fraction and duration of mechanical ventilation ( P
