Economic burden and managed care considerations for the treatment of insomnia.

Insomnia is a common sleep disorder in adults that can have many negative health impacts. The aggregate total of direct and indirect insomnia healthcare costs has been estimated to be as high as $100 billion US dollars per year. In addition to the societal cost burden, insomnia also negatively affects patients' quality of life (QOL), including social and occupational functioning or productivity as well as impaired cognition or mood. Insomnia may also exacerbate and increase morbidity and complications from psychological disorders, such as depression, as well as have serious consequences, such as increased risk of suicide. Comorbidities, medications, and/or psychosocial contributors may negatively influence QOL. Many medications for the treatment of insomnia have adverse effect (AE) profiles that increase the risk of falls and related injuries, cognitive impairment, and motor vehicle accidents. These AEs place additional burden on the already vulnerable older adult population and those with comorbidities. Managed care organizations must evaluate clinical considerations, including safety profiles and the negative impact of disease on patients' QOL, to develop strategies for cost-effective treatment plans for patients with insomnia and to ensure appropriate use of these medications.
