Insomnia is one of the most common complaints in medicine, driving millions of clinic visits each year (Table 1). It is estimated that approximately 30% of individuals report at least short-term insomnia symptoms and 10% report chronic insomnia. These rates are even higher in groups that may be more susceptible to insomnia, including women, the elderly, and those of disadvantaged socioeconomic status (Ohayon MM. Sleep Med Rev.). While most patients with insomnia find their sleep difficulties self-resolve within 3 months, a substantial number of patients will find their insomnia to persist for longer and require intervention (Sateia MJ et al. J Clin Sleep Med. ).
For individuals requiring treatment, cognitive behavioral therapy for insomnia (CBT-I) is considered first-line therapy by the American Academy of Sleep Medicine for both acute and chronic insomnia. Unfortunately, obtaining CBT-I for a patient is often a challenge as the number of trained therapists offering this service is limited, resulting in long wait times or, in some cases, a complete lack of access to this treatment option. Judicious use of sedative-hypnotic medications may be a reasonable alternative for patients with insomnia who are unable to undergo CBT-I, who are still symptomatic despite undergoing CBT-I, or, in some cases, as a temporary treatment (Sateia MJ et al. J Clin Sleep Med.).
