This review sought to assess the effectiveness of nonpharmacological interventions for sleep promotion in critically ill adults in the intensive care unit (ICU). It also sought to establish whether nonpharmacological interventions are safe and clinically effective in improving sleep quality and reducing ICU length of stay and whether nonpharmacological interventions are cost-effective.1
