Description of intervention(s) / exposure
This project will leverage and expand the validated HeadCheck application (app) into an app and website to collect data elements predictive of outcome following mTBI across all States and Territories in Australia. Participants will be followed up through their preferred online platform (app or website) to complete a concussion symptom questionnaire on day 1, 3, 7 post injury. At 2 weeks following injury, and then fortnightly until 3 months post injury (or until symptom resolution), participants with persistent symptoms will be prompted to complete questionnaires to assess concussion symptoms and quality of life, as well as reporting if they have returned to their pre-injury levels of physical activity, sport, work and/or study. These same questions will be administered monthly from 3 months following injury for people who are still experiencing concussion-related symptoms until symptom resolution.

In Phase 1 of the study (approx. first 12 months of data collection), participants will be treated using the established care pathways in the HeadCheck app. The established care pathways are the tasks and activities that participants are instructed to do within the app based on their symptom severity. An example of the tasks and activities that form part of the established care pathways within the app are 'See a GP/health professional if you feel any of your symptoms are getting worse or you see any of these symptoms: 1. Change in behavious, 2. Vomitnig, 3. Worsening headache, 4. Double vision, 5. Excessive drowsiness', 'Do 1-2 hours of work/study/school at home', 'Do gentle physical activitiy' or 'Read about what to do following a head knock' . Phase 1 data will then be used to inform a revision of the care pathways that will be built into the HeadCheck app and administered to participants in Phase 2 in year 2 of the study. The revised care pathways will be informed by the machine learning analysis of which factors predict symptom resolution, in conjunction with consensus from the AUS-mTBI Steering Committee. An example of a change in the pathway may be for someone who has distinct grouping of vestibular symptoms as a result of their concussion, they may be advised to seek timely input from a vestibular physiotherapist, as well as general advice from their GP. In app analytics will be used to monitor adherence to the activities suggested to participants through the app intervention.

The AUS-mTBI Steering Committee consists of: expert researchers in traumatic brain injury, neuroscientists, data scientists, neuropsychologist, sports physicians, people with lived experience of concussion, people from Aboriginal and Torres Strait Islander background, Emergency Physicians, Occupational Therapists, registry and data linkage experts.

Treatment: Devices
Comparator / control treatment
Participants recruited in phase 1 of the study and treated using the existing HeadCheck care pathways will form the control group. The treatment will be a guided recovery program through the app based on an individuals concussion symptoms and activity tolerances. The treatment program (care pathways) will provide 2 weeks of suggested activities as the treatment.

Other design features
All participants recruited in the first year of the study will be enrolled into the 'control group', using the established treatment pathways within the Headcheck app. Participants in the second year of the study will form the 'treatment group', with treatment pathways revised based on the findings of the first year of the study regarding predictors of persistent post concussion symptoms (PPCS). The time to symptom resolution will be compared between the treatment group and control group at the conclusion of the study to evaluate the revised treatment pathways trialled in year 2 by the treatment group.

Efficacy
Statistical methods / analysis
Based on similar research in other countries, feasible outcomes can be generated from population sizes as low as 37 individuals, through to large longitudinal cohorts of more than 10,000.
This project aims to recruit 5000 participants across Australia during each the first and second year of recruitment. With wide recruitment we aim to have a population-based capture of adults and children who have experienced a mTBI. Custom machine learning models and related algorithms (such as RandomForests, XGBoost, etc.) will be built to analyse this high-quality dataset to predict outcomes and identify better care pathways for people following mTBI. Model robustness and uncertainty will be tested using extensive sensitivity analyses (including probabilistic sensitivity analyses) and calibration to observed trends in outcome.
Baseline characteristics will be compared between men and women using Chi-square tests for categorical variables and t-tests for continuous variables. The analyses will be repeated by age, mechanism of injury, outcome (PPCS or no PPCS), nature of injury (single event or sequelae), and symptoms at presentation. All eligible participants will be included in the analyses.
Analysis of data not involving machine learning models will be performed using R, SPSS or Stata V17 statistical software (StataCorp LP, College Station, Tex).
