SLEEP HEALTH PACKAGES to guide the management of chronic insomnia and obstructive sleep apnea (OSA) in Primary Care (PC) will be provided to participating intervention-arm clinics:

A. EDUCATION & CLINICAL PRACTICE GUIDELINES (CPGs)



(1) Education for GPs and Practice Nurses (PNs): Approximately 6 hours (2-hours on chronic insomnia and up to 4-hours on sleep apnoea) (GPs/PNs) and 1-week of in-service training (PNs). The ~6-hour course will be delivered in-person to groups of PC-clinicians by a Specialist Sleep Physician (SSP), a Specialist Sleep Nurse (SSN), and a Specialist Sleep Psychologist. This education will have a similar format to that of our team’s RCT comparing OSA management in a PC versus specialist setting (Chai-Coetzer et al. 2013 JAMA), and will consist of educational lectures and a hands-on workshop where clinicians can learn more about diagnostic tests and treatments for OSA and insomnia. We will discuss and provide attendees with a copy of our PC CPGs. In-service training will be led by a SSN, take place in a sleep clinic setting and will incorporate CPAP set-up and follow-up.

(2) Online CPGs: User-friendly PC guidelines.
These CPGs have been developed by a senior academic/clinical GP, and have been edited by our multi-disciplinary National Centre for Sleep Health Services Research team. The purpose is to provide a user-friendly, PC-specific guide to insomnia and OSA for clinicians, which complements our online education modules and in-person training.

(3) (Optional) Online education modules will be made available: Developed/updated in conjunction with the Royal Australian College of General Practitioners (RACGP) and Australasian Sleep Association.
Our 2 RACGP gpLearning Modules (Insomnia and OSA Management in General Practice) are self-administered education modules, designed to provide general practitioners (GPs) with evidence-based information on the identification, diagnosis, management, and follow-up of patients with insomnia and OSA in a PC-setting. Each module takes about 1 hour to complete. The insomnia module includes 'slides' with information and diagrams, multiple-choice questions, and short-answer questions about the definitions, diagnosis, management, and a case scenario about insomnia management. The OSA module covers: OSA definition, differentiation between simple snoring and OSA, economic cost of sleep disorders in Australia, prevalence, pathophysiology, risk factors, consequences of OSA, assessment, treatment and referral options.


B. SCREENING & POINT-OF-CARE TESTING
Eligibility will require: Chronic Insomnia, diagnosed via Sleep Condition Indicator questionnaire or high-risk of symptomatic moderate-severe OSA, diagnosed using a combination of questionnaires (OSA50 and Epworth Sleepiness Scale i.e. ESS).


C) TREATMENT & ACCESS/REFERRAL PATHWAYS.
Those who are diagnosed with chronic insomnia and/or OSA will be offered the treatment options described below, with specific strategies to monitor adherence, outlined below.

INSOMNIA:
GP/PN brief CBTi: We will provide training for PNs in this brief behavioural intervention as part of our 1-week education program. Brief CBTi is a manualized intervention delivered over 4 weeks, which can be delivered during a combination of in-person and phone/tele-health appointments. The first session is 45 minutes, and the follow-up sessions are approximately 30-45 minutes. Adherence to brief CBTi will be defined as the number of sessions completed. Briefly, the topics covered are: basic information about insomnia, the processes which control sleep (sleep drive and circadian processes), an overview of insomnia (prevalence, characteristics, symptoms), and healthy sleep hygiene behaviours. This information is important to ensure the patient understands the rationale for the behavioural therapies (bedtime restriction therapy and stimulus control therapy) which are introduced and adjusted over the subsequent 3 sessions.

Online CBTi: Sleepio is a leading digital sleep-improvement program, based on CBTi techniques. Sleepio’s core program consists of 6 weekly sessions in which a virtual sleep expert talks the participant through personalised techniques. Each session lasts about 20 minutes, and is tailored to progress and problems. Between sessions, participants complete an online Sleep Diary to track progress and are sent reminders to aid adherence. Throughout, participants are supported by a community of other users, 10 online tools and a library of over 100 articles. Adherence will be defined as the number of sessions completed. PNs will contact patients approximately 3 weeks after referral for Sleepio, to check on program commencement and offer motivational advice to continue with CBTi recommendations.

CBTi from a Specialist Sleep Psychologist: This is the current best practice for insomnia management but remains underutilised. GPs may refer patients to existing local sleep psychologists. Our supporting specialist centre has psychologists who will provide this service in-person/via telemedicine. The service will consist of a 6-week individually tailored program. Adherence will be defined as the number of sessions attended. During CBTi, a patient is provided with information to ensure that they understand the rationale for the main component of this therapy, bedtime restriction therapy, which aims to modify the bedtime routine/behaviours over several weeks to gradually increase sleep pressure/drive in the evening, promote more rapid sleep onset, reduce the duration of nocturnal awakenings, and reduce the conditioned relationship between the bedroom/bedtime routine and an insomnia response. Therapy is personalised based on self-reported nightly sleep patterns and bedtime routine over the past 1-2 weeks and often begins by reducing the amount of time spent in bed to match perceived sleep duration, then maintaining this routine over the next 1-2 weeks. After sleep becomes more consolidated, time spent in bed is gradually extended until a comfortable equilibrium between sleep time, time in bed, and sleepiness is achieved.

Participant flow: After insomnia is confirmed, the participant will be offered either brief CBTi or online CBTi. If the GP/PN determines that these options are not suitable, if the participant refuses those options or a poor response is noted at the GP follow-up (within 1 month), they will be offered referral to a psychologist. Our CPGs will provide examples of circumstances in which direct referral to a sleep psychologist is recommended (e.g. shift work, severe or uncontrolled psychiatric disturbance, based on screening questionnaires) but will not be prescriptive.

OSA:
(0) Patients with a high-risk of symptomatic, moderate-severe OSA based on the OSA50 and ESS questionnaires will be referred for a single-night at-home ApneaLink sleep study to confirm OSA. Patients with no/mild OSA (3% Oxygen desaturation index <16) will receive ongoing management but will not be eligible for CPAP therapy. Patients with moderate or severe OSA (oxygen desaturation index =>16) will be eligible for CPAP therapy.

Participants with mild and moderate-severe OSA will be provided lifestyle advice via written information (e.g. weight loss, minimise alcohol intake, avoid sedative-hypnotics, supine avoidance, good sleep hygiene, etc.).


(1) Continuous Positive Airways Pressure (CPAP): Healthcare card holders and pension card holders will be offered nurse-delivered CPAP equipment, setup and review appointments in the general practice clinic. Non-healthcare/pension card holders will receive initial determination of required CPAP pressure in the general practice setting and will be referred to private CPAP clinics for CPAP setup and ongoing management. The initial visit will take one hour. In that session, the patient will receive information about why CPAP is needed, how it works, mask fitting, CPAP safety and side effects and how to operate and maintain equipment, then invite the participant to return at 2 weeks. For most participants, follow-up will be undertaken at three-monthly intervals thereafter. CPAP adherence will be defined as average nightly use of CPAP. Patients with private health insurance will be reimbursed $600 toward their purchase of CPAP. This is to reflect average private rebate for CPAP therapy from private insurers.

(2) Mandibular Advancement Splints (MAS): MAS devices (and equivalent) move the lower jaw forward during sleep to increase the pharyngeal airway space and prevent collapse of the pharynx, and are effective for most patients. A list of preferred providers will be given to GPs. Adherence to these devices will be measured via self-report of nightly use.

(3) Referral to a SSP: Our CPGs indicate when sleep specialist management will be recommended e.g. (1) severe comorbid obesity; (2) neuromuscular disease; (3) psychiatric/cognitive disease or impairment likely to interfere with participation; (4) hospitalization within 3 months for coronary or cerebrovascular events; or (5) severe lung disease. Treatment/adherence monitoring will be in accordance with usual SSP protocols.

Participant flow: After moderate-severe OSA is confirmed on the ApneaLink study, the participant will be offered a combination of CPAP therapy and lifestyle advice. If CPAP is refused, ineffective or poorly tolerated, then referral to a dentist for a MAS will be recommended. If MAS is refused, ineffective or poorly tolerated, referral to a SSP will be recommended.

A total 12-month follow-up is planned.

Practices, GPs, PNs, Practice Managers, and patients will be reimbursed for trial-related activities, including attendance at educational programs, throughout the trial that are in addition to usual care.

Patients at intervention sites will be reimbursed $10 per questionnaire battery completed, and $20 for (optional) qualitative interviews (up to $60 total).

Treatment: Other
Comparator / control treatment
The control arm will have 'Treatment as Usual (TAU)' i.e. usual clinical intervention for the 12-month duration of the study. The TAU group clinicians will not receive any specific training or interventional materials and will be asked to continue with their usual management of sleep disorders. Patients with sleep disorders (suspected OSA and chronic insomnia) will still be invited to participate in the data collection process (i.e. sleep disorder screening and completion of self-report questionnaires). After completion of the trial, the TAU sites will be provided access to intervention education, and interventions for patients recruited into the trial including; Sleepio, streamlined access to ‘sleep’ psychologists at the Adelaide Institute for Sleep Health specialist insomnia program, and patients with OSA that are awaiting review at the Southern Adelaide Local health Network Sleep Service will receive facilitated access to sleep physicians and funded CPAP equipment if eligible ((i.e. confirmed moderate-severe OSA and possess a Health Care Card or Pensioner Concession Card).

Patients at control sites will be reimbursed $10 per questionnaire battery completed ($40 total during trial).

Cost-effectiveness

The cost-effectiveness of the intervention relative to TAU will be determined using a decision-analytic model. Within-trial incremental health-system costs will be estimated using MBS, pharmaceutical benefits scheme (PBS), and diagnosis-related group (DRG) data with patient private costs collected using a resource use questionnaire. Within-trial effectiveness will be modelled using the primary outcomes (for OSA and insomnia) and QALYs (estimated using patient responses to the AQoL-4D). To determine beyond-trial cost-effectiveness, a comprehensive systematic literature search will be carried out to identify longer-term published cost and utility data for the model. Costs associated with development and delivery of the intervention will be estimated using administrative data collected as part of the trial. The health economics analysis will include cost-effectiveness, acceptability, cost-savings, expected net loss curves to inform decision makers of the optimal strategy at any threshold for different subgroups and the uncertainty around this decision. We will also collect data on the length of time for appointments required in order to estimate the appropriate level of MBS funding to aid a future Medicare Advisory Service Committee (MSAC) application.

Eligibility
Key inclusion criteria
General Practitioners: We will include GPs who are currently practising in Australia and give written informed consent.

Insomnia: To be eligible for inclusion, a potential participant with chronic insomnia must meet diagnostic criteria based on a Sleep Condition Indicator (SCI) questionnaire score of less than or equal to 16 (which has been shown to correctly identify 89% of patients with insomnia, and correctly exclude 82% of those without) and report insomnia symptoms for at least 3 months i.e. a higher SCI score indicates better sleep. The SCI scale has been reverse-coded on GP screening forms, to align with the other questionnaires (higher scores = worse symptoms/health).

Obstructive Sleep Apnea (OSA): To be eligible for inclusion, a potential participant must meet the following criteria:
• OSA-50 questionnaire score of greater than or equal to 5 (indicating high probability of moderate-severe OSA) AND Epworth sleepiness scale (ESS) score of greater than or equal to 8 (indicating at least mild symptoms of sleepiness).

Additional general eligibility criteria:
Inclusions: At least 18 years of age, able to provide informed consent and complete patient questionnaires, currently living in Australia.

Exclusions: Drug/alcohol problems, terminal illness, unstable or poorly controlled psychiatric illness or significant cognitive impairment which would affect patient’s ability to understand or comply with study requirements, epilepsy or muscle spasms requiring benzodiazepine, women who are currently pregnant, limited English comprehension, no access to MBS-PBS (e.g. not Australian resident or citizen), or Department of Veterans Affairs card holder.

Statistical methods / analysis
In this cluster-randomised controlled trial, we will randomise 20 clinics, (10 into intervention and 10 into Treatment As Usual (TAU) arms). To detect our primary outcomes for OSA and insomnia, respectively, we will require 400 new cases of OSA, and 400 insomnia cases. Australian BEACH study data indicates that we are likely to exceed our targets, since in 12 months 20 GPs will likely encounter 2080 insomnia (~2 insomnia cases/week/GP) and 1560 OSA cases (~1.5 OSA cases/week/GP).

• OSA: The sample size for the OSA primary outcome 1- the Epworth Sleepiness Scale (ESS), was based on a non-inferiority test of two means for a parallel, two-group cluster-randomized design using PASS 2023, version 23.0.1. Assuming a non-inferiority margin of -2, 10 clusters per Group, 90% power and a Type I error rate (a) of 0.025, common subject-to-subject SD for both groups = 4, ICC=0.01, coefficient of variation of cluster sizes = 0.65 a total of 200 subject is required (10 subjects per cluster). Because patients are recruited who are at risk of having OSA with an elevated ESS, the number of subjects was doubled (n=400) in order to recruit adequate numbers of moderate to severe patients with OSA (~half) to give practice nurses and GPs adequate experience in the diagnosis and management of OSA and account for 20% drop out rate over 12 months.

• INSOMNIA: Primary outcome 2, patient-recorded/reported use of sedative-hypnotic medication (nights per week, in the last 2 weeks, use of benzodiazepines, non-BZD hypnotics (‘z-drugs’; e.g. zopiclone, zolpidem), and antidepressants/antipsychotics (e.g. trazodone, amitriptyline, mirtazapine, quetiapine) at the 12-month follow up relative to baseline use for the model of care compared to TAU. The sample size was based on a test of two means for a parallel, two-group cluster-randomized design using Stata/SE, version 18.0. Assuming a reduction of 1.82, 10 clusters per Group, 80% power and a Type I error rate (a) of 0.05, common subject-to-subject SD for both groups = 4.9, ICC=0.01, a total of 260 subject is required (13 subjects per cluster). It is estimated that only 75% of the participants will be using sleeping medications and therefore the sample size was inflated accordingly to 400 participants in total (20 subjects per cluster) allowing for a 10-15% drop-out rate over 12 months.

In regard to primary outcome 3, the Sleep Condition Indicator outcome, the cluster size required to detect a conservative delta of 3 between TAU and PC is 9 individuals, given a control-group mean of 14.97, given that both groups have 10 clusters and that the standard deviations of the two groups are both 5.93; assume a two-sided test with a 5% (alpha) significance level, a power of 90%, and an intraclass correlation of 0.01, and assume that both groups will have the same cluster size. Therefore, the total sample size is (9*10)*2=180. Assuming a drop out rate of 15%, then n=210 are required. The SCI outcome will be therefore adequately powered based on the sample size required for the sedative/hypnotic medication reduction outcome.

Summary
Brief summary
This novel implementation study represents a major step towards improving management of sleep disorders in primary care (PC). The two most common sleep disorders, chronic insomnia and obstructive sleep apnea (OSA), affect >4 million Australians, and are associated with broad ranging negative physical and mental health outcomes, as well as reduced safety and productivity, costing over $66 billion annually. People with sleep disorders commonly receive care that is far from best practice and potentially dangerous. A lack of sleep-specific training for GPs contributes to widespread under recognition of sleep disorders, and an over-reliance on specialist care. Long waiting periods for specialist OSA care have led to a rise in vertically integrated business models from pharmacy/corporate treatment device suppliers, without adequate medical input to manage these disorders, and often complete separation from a person’s usual medical care. Our research group and others, have demonstrated in randomised trials that GPs and PNs can manage OSA, producing equivalent patient outcomes to those in specialist centres at significantly lower cost. Similarly, for insomnia, despite clinical guidelines recommending cognitive behavioural therapy (CBTi) as the first line treatment, the majority of patients receive sedative/hypnotic drugs with potentially dangerous side effects, and do not get access to the CBTi that would address the underlying cause of their insomnia. To address this, our study will utilise a simplified Model of Care for screening, diagnosis and treatment of OSA and chronic insomnia in PC, and a suite of practice change support tools. These tools are currently being developed and will be translated through our NHMRC CRE (GNT1134954) – National Centre for Sleep Health Services Research, and include simple clinical guidelines, education modules, eHealth decision support tools, and referral pathways. This will facilitate and demonstrate the uptake, efficacy and cost-effectiveness of the new sleep health services model.

We hypothesise that our implementation strategy for improving sleep disorder management in PC settings will result in management that is:
a) better aligned with recommendations of evidence based clinical guidelines;
b) more cost-effective in terms of patient outcomes/waiting times and cost when compared with usual care;
c) feasible and acceptable from the perspective of GPs, PNs and patients, indicating viability for up-scaling the project.
