Insomnia management in Australian General Practice Prof Nick Zwar & Dr Alexander Sweetman

Co-Hosts: Professor Nicholas Zwar (Executive Dean & GP) & Dr. Alexander Sweetman (Senior Research Fellow & Sleep Psychologist) and Michelle Odayan (MyHealth Academy)

Episode Overview

While up to 10–15% of Australian adults suffer from chronic insomnia, primary care has historically relied on sedative-hypnotics, writing prescriptions in up to 90% of insomnia presentations. In this episode, Prof. Nicholas Zwar and Dr. Alexander Sweetman unpack the critical clinical shift toward Cognitive Behavioral Therapy for Insomnia (CBT-I), the global gold-standard first-line treatment.

They discuss the massive barrier to accessing CBT-I (only 1% of chronic sufferers currently receive it) and reveal how a free, Australian-developed digital program called Bedtime Window is giving GPs an effective, evidence-based pathway to cure insomnia and support elegant de-prescribing.

Key Clinical Takeaways for GPs

Insomnia is a Chronic Disorder, Not Just a Symptom: Chronic insomnia is defined as sleep dissatisfaction occurring 3+ nights a week for 3+ months. It is highly comorbid with depression, anxiety, chronic pain, and cardiovascular diseases, and is a significant predictor of future depressive episodes.

CBT-I is the First-Line Cure, Not Sleep Hygiene: Standard sleep hygiene advice (e.g., avoiding caffeine, regular wake times) rarely resolves chronic insomnia. CBT-I is a multicomponent therapy heavily focused on behavioral techniques like stimulus control and bedtime restriction therapy.

The Power of Digital CBT-I: To bypass the severe shortage and cost of trained sleep psychologists, GPs can utilize Bedtime Window, a free, 5-session digital CBT-I program that uses personalized algorithms and clinician-led videos to achieve a 90% mild-to-normal sleep remission rate for completers.

An Elegant De-Prescribing Helper: Digital CBT-I is highly effective whether patients are actively taking sleeping pills or not. In a trial of 950 patients referred by GPs, 45% of patients completely stopped using sedative-hypnotics by the end of the Bedtime Window program.

Navigating Patient Resistance & Stigmas:

The "It's Not in My Head" Objection: If patients reject "psychological" help, reframe CBT-I as a practical, behavioral routine program (like physical rehab for sleep) rather than talk therapy.The Tapering Tussle: Do not make medication cessation a prerequisite to starting CBT-I. Run them concurrently; as behavioral therapy fixes the sleep architecture, patients naturally find their medications become redundant.

Medicare Eligibility: GPs can initiate an Australian Medicare Mental Health Treatment Plan using chronic insomnia disorder as the primary mental health diagnosis.
