Abstract
Hospitalization is a period of acute sleep deprivation for older adults owing to environmental, medical, and patient factors. Although hospitalized patients are in need of adequate rest and recovery during acute illness, older patients face unique risks owing to acute sleep loss during hospitalization. Sleep loss in the hospital is associated with worse health outcomes, including cardiometabolic derangements and an increased risk of delirium. Because older patients are at risk of polypharmacy and medication side effects, a variety of nonpharmacologic interventions are recommended first to improve sleep loss for hospitalized older adults.
