Critical\u2010care nurses maintain that patients with disrupted sleep appear to develop delirium. We sought to explore whether improving sleep in the critically ill patients reduced the incidence and duration of delirium. Our review of five relevant studies suggests that there is low\u2010quality evidence that improving sleep may reduce the incidence of delirium. The bidirectional association between delirium and sleep stymies research in this area, and thus, establishing cause and effect, is difficult. Research exploring other patient\u2010centred outcomes, such as pain intensity, suggests that enhancing sleep may improve these outcomes.<\/jats:p>","DOI":"10.1111\/nicc.12906","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T04:05:29Z","timestamp":1680581129000},"page":"738-743","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Does improving sleep for the critically ill reduce the incidence and duration of delirium?
