Association between sleep disorder and delirium in adult patients undergoing cardiac surgery: a retrospective cohort study.

ABSTRACT:

Background

Compared to non-cardiac surgical patients, those undergoing cardiac surgery exhibit a higher prevalence of sleep disturbances and delirium, yet limited research has specifically examined this association in the cardiac surgical population. This study investigates the association between sleep disorders and the risk of delirium in patients after cardiac surgery, aiming to raise public awareness of the relationship.
