The American Academy of Sleep Medicine (AASM) commissioned fi ve Workgroups to develop quality measures to optimize management and care for patients with common sleep disorders including insomnia. Following the AASM process for quality measure development, this document describes measurement methods for two desirable outcomes of therapy, improving sleep quality or satisfaction, and improving daytime function, and for four processes important to achieving these goals. To achieve the outcome of improving sleep quality or satisfaction, pre-and post-treatment assessment of sleep quality or satisfaction and providing an evidence-based treatment are recommended. To realize the outcome of improving daytime functioning, pre-and post-treatment assessment of daytime functioning, provision of an evidence-based treatment, and assessment of treatment-related side effects are recommended. All insomnia measures described in this report were developed by the Insomnia Quality Measures Workgroup and approved by the AASM Quality Measures Task Force and the AASM Board of Directors. The AASM recommends the use of these measures as part of quality improvement programs that will enhance the ability to improve care for patients with insomnia.

Effi cacious treatments exist. However, the approach to management of insomnia is not standardized, particularly outside of sleep medicine centers. The aim of this paper is to describe the development of quality measures that can be applied to the management of insomnia patients across a wide range of ages and care settings.Insomnia is characterized by diffi culties initiating, sustaining, or obtaining qualitatively satisfying sleep despite adequate sleep opportunities and circumstances, resulting in impaired daytime functioning.1,2 Insomnia can occur across the majority of the human lifespan, from childhood years to old age. Over 33% of adults experience insomnia at least intermittently, whereas 10% to 22% suffer chronic sleep diffi culties.3-8 While prevalence data are more sparse for younger age groups, insomnia symptoms may be seen in as many as 20% to 40% children and teenagers, with slightly higher rates among girls and those with symptoms of mood disturbance. 9,10 While its signifi cance is often minimized, 11,12 persistent insomnia is associated with daytime fatigue, decreased mood, impairment in social/vocational functioning or poor school performance, and reduced quality of life.1,2,13-15 Insomnia also increases the risks for serious medical disorders, traffi c and work-site accidents, alcohol/drug abuse, and major psychiatric illnesses. 4,[16][17][18][19][20][21][22] When insomnia is comorbid with a psychiatric illness such as major depression, it c...
