Both these disorders can occur separately, but if they co-occur, this is termed COMISA. Approximately 30–50% of people with OSA have comorbid insomnia, and 30–40% of people with chronic insomnia have comorbid OSA.9,12 A recent population-based study reported that 11% of Australian adults report symptoms of COMISA.13
The ‘gold standard’ measure of OSA presence and severity is an overnight sleep study (Table 1).25 The most common single metric to determine OSA presence and severity is the apnoea-hypopnoea index (AHI), representing the average number of airway narrowing and closure events occurring per hour of sleep.24 Identifying the most appropriate management approaches for OSA also requires consideration of lifestyle factors, symptoms and consequences, occupation, chronic conditions, and other sleep conditions. Self-report questionnaires may be used to screen for a high-risk of OSA and identify patients suitable for referral and consideration of overnight sleep study assessment (Table 1).24
Although evidence-based guidelines unanimously recommend avoiding long-term use of hypnotics, they are indicated for a minority of patients that present with severe acute insomnia that is causing significant psychological distress or functional impairment.29 Most people who experience short-term insomnia symptoms (1–2 weeks) can be reassured that sleep will return to ‘normal’ after the underlying precipitant has subsided, without targeted treatment (i.e. hypnotic medicines).29,33 For those who experience persistent insomnia, cognitive behavioural therapy for insomnia (CBTi) is the first-line treatment. Pharmacotherapy may be considered in patients with severe insomnia that is causing significant impairment or distress (e.g. times of acute work/exam stress, bereavement).34
Tailored recommendations for non-CPAP therapies may also be provided to patients with different levels of OSA severity and presenting features.17 For example, weight management advice where indicated, positional devices (in the presence of supine-predominant OSA), mandibular advancement splints (in patients with mild-to-moderate OSA), and upper airway surgery are effective treatments that may be tailored to each individual patient.24

Case scenario
Nia, 36 years old, presents to the pharmacy for advice, reporting difficulties falling asleep for the past 5 months. These problems started after a sporting injury. Although her injury has improved, Nia is still having difficulties sleeping. She reports that as soon as her head hits the pillow, she feels like her mind springs into action. You confirm that she isn’t on any medicines, has no medical conditions and works full-time in the retail industry with regular daytime hours.
