Sleep and other factors associated with mental health and psychological distress after intensive care for critical illness.

Abstract

Purpose: Some patients who survive intensive care unit (ICU) treatment report psychological sequelae during recovery. This study examined factors associated with psychological outcomes of former ICU patients up to 6 months after hospital discharge. Methods: Participants (n = 195) were adult survivors of ICU enrolled in a multicenter trial of physical rehabilitation after hospital discharge. The 36-Item Short-Form Health Survey (SF-36), the Impact of Events Scale (IES) and the Depression, Anxiety and Stress Scales were completed, and sleep rated on a five-point scale at weeks 1, 8 and 26; clinical and demographic data were obtained from patient records.
