The measurement of insomnia treatment efficacy has evolved over time. Historically, patient report measures were used to assess sleep the previous night, and, although important, these measures were not objectively validated. While the advent of polysomnography complemented patient reports of nocturnal sleep, few studies have evaluated daytime functioning and impact of impaired sleep on comorbid medical and psychiatric illnesses as measures of the efficacy of hypnotics. In the future, therapeutic endpoints will focus on important factors associated with insomnia, such as enhanced alertness, improved outcomes associated with augmentation therapy for depression, reduction in pain severity, and decreased sleep disturbances associated with hot flashes.
