Description of intervention(s) / exposure
Occupational Therapy (OT) Referral Pathway (Cohort 2):
The OT referral pathway aims to provide specialist follow up for patients seen in ED for a head injury, outside of business hours and demonstrating characteristics most at risk of experiencing functional deterioration. This pathway is being implemented as routine care regardless of a patient's participation in the study.

Patients will be referred to their respective services by the ED treating team:
-Adults (over the age of 18yrs, OR no longer attending formal schooling due to lifestyle and behaviour factors)
-Paediatrics (5yo or school attending, and under the age of 18yrs).
Patients will be provided with written educational material about head injury by the ED team upon referral to the OT pathway.

The OT clinic provides telehealth counselling sessions aimed at education, symptom management and intervention based on patient goals and occupational engagement to promote client centred care and re-integration into community / productivity roles.

Initial assessment (which will take up to 30 minutes) will be completed over telephone by an Occupational Therapist and aims to obtain a detailed history, impact of symptoms on daily functioning including the administration of the Rivermead Post Concussion Symptom Questionnaire, WHODAS 2.0 and if clinically indicated a Vestibular Screening Tool.

Patients will be offered subsequent reviews as clinically indicated, focusing on their re-integration and patient specific goals. As such, the number of times of intervention and duration of intervention will vary depending on the patient's presentation and may range from a single 30 minute follow up phone call to several 30-60minute appointments over 3-6 months. (Nature, duration and attendance at each session will be recorded and monitored as part of the data collection process for this research). Sessions may be administered via telehealth, telephone or face to face as required. Face to face sessions will be conducted at the Gold Coast University Hospital, OT clinic rooms.

Intervention provided on the pathway is based on a local evidence-based clinical guideline and may include the following management:
- Normalising symptoms and expected outcomes
- Reassurance
- Gradual return to activities and life roles
- Strategies to manage symptoms;
- Sleep hygiene
- Relaxation and modification of environment
- Graded return to daily routine, activity and employment responsibilities or occupational roles
- Graded return to school and leisure activities
- Fatigue management
- Sensory modulation approach
- Relevant cognitive assessment and intervention
- Mental health and associated symptoms and referrals
- Visual disturbances associated referrals
- Vestibular and balance disturbances and associated referrals

Interventions are provided until symptoms resolve, or significant improvement has been reported, as identified in either goal achievement and/ or perceived symptoms within the Rivermead Post Concussion Symptom Questionnaire. Alternative indicators for referrals and discharge options will also be explored including referral to GP, community psychology or Vestibular Physiotherapy for ongoing management and care.

Comparator / control treatment
Pre-implementation usual care (Cohort 1):
Prior to the implementation of this direct referral pathway- there was no formal referral process for follow up of these patients, or standardised treatment follow-up within the Hospital Health Service (GCUH and Robina Hospitals). Some patients were referred to Occupational Therapy on an ad hoc basis with no formal or coordinated treatment pathway. The time period this data will be collected will be approximately 4-5 months prior to the implementation of the pathway (being approximately March 2022 to July 2022).

Statistical methods / analysis
Between group comparisons between Cohort 1 and 2 at 4 weeks and 3 months-post injury will be made on all continuous data (i.e., client outcomes, service outcomes) using a linear regression model, and for proportion data (i.e., readmission rates), a logistic regression model will be undertaken. To compare within group differences from admission to discharge within the OT clinic for Cohort 2, a linear regression model will be undertaken between admission to the clinic and discharge from the clinic. We will include covariates in the model known to have a potential impact on outcomes (e.g., gender, age, paediatric vs adult, previous OT input). Where paediatric versus adult is found to have a significant interaction effect on outcomes, then a separate sub analyses will be undertaken.

To answer our research question regarding the incidence of patients with mTBI with Persistent Post Concussion syndrome sequalae, data will be described as number, and percentages with 95% confidence interval. To describe the Occupational Therapy interventions undertaken, descriptive statistics will be undertaken and average proportion of the types of intervention provided to Cohort 2 together with 95% confidence intervals will be reported. We will also continue to consult with Dr Ian Hughes, GCHHS Biostatistician for statistical advice for this study.
Measures of participant time from work, time from school, and time caring for a child/minor during recovery, as well as resource utilisation to administer the OT intervention will be used for an economic analysis.

Qualitative analyses:
Audio recordings for the focus group will be transcribed and inductively coded using qualitative content analyses in NVivo . This will involve meaning units being coded and grouped into related descriptive categories by a member of the research team and checked by a second team member, with any discrepancies discussed by a third member until a consensus is reached. The same approach will be used for open-ended responses for satisfaction questionnaire data.

Summary
Brief summary
Mild Traumatic Brain Injury (mTBI) is a significant burden to Queensland emergency departments (EDs) in adults and children. Between 2019-2020, there were over 1800 presentations of isolated mTBI to Gold Coast Hospital Health Service (GCHHS) EDs, presenting outside of usual business hours with 26% re-presented within the first 6 weeks of their initial presentation, many of which were related to the initial injury. Management pathways to support this population and reduce the high rate of re-presentations must therefore be prioritized. With this in mind, the Occupational Therapy (OT) Outpatient Service are implementing an innovative practice model involving specialist OT follow up for these patients to facilitate recovery and linking into appropriate specialty referrals where indicated to prevent ED representations.
The primary aim of this research is to evaluate the impact of this Occupational Therapy (OT) intervention pathway for patients presenting to ED with a mTBI outside of business hours compared to pre-implementation care. The study secondly aims to evaluate the process of implementing the pathway in relation to adherence, patient satisfaction, and staff experience. It is anticipated that the implementation of the OT pathway will lead to decreased ED readmission, enhanced clinical outcomes (including reduced functional burden and disability and days missed of work/school) and decreased ED length of stay for monitoring of symptoms.
