Sleep Disorders in Patients Admitted to an Internal Medicine Ward: An Observational Study

Abstract

Background and Aims: Sleep-wake rhythm disorders are common in hospitalized patients, often underdiagnosed. Systematic assessment of these disorders can improve the quality of care. The objective of our observational study conducted at the General Medicine Unit was primarily to assess the prevalence of sleep disorders in hospitalized patients and to correlate sleep-wake alterations with metabolic, infectious, or neurological disorders, analysing the association with length of stay and the onset of delirium or disorientation.
