Sleep in Hospitalized Patients

Abstract

Hospitalized patients frequently have disordered and poor-quality sleep due to a variety of both intrinsic and extrinsic factors. These include frequent nighttime intrusions, insomnia related to pain and unfamiliar environments, dark conditions during the day with loss of natural light, and disruption of natural sleep cycle due to illness. Sleep wake disturbances can result in deleterious consequence on physical, emotional and cognitive status, which may impact patient satisfaction, clinical recovery, and hospital length of stay. Despite this, clinicians frequently fail to document sleep disturbances and are generally unaware of best practices to improve sleep quality in the hospital. The purpose of this review is to discuss sleep disturbances in hospitalized patients with a focus on causes of sleep disturbance, effect of poor quality sleep, high risk populations, considerations for surveillance and prevention, as well as pharmacologic and non-pharmacologic options for treatment.
