Description of intervention(s) / exposure
This is a Phase II safety and efficacy study of CovidCare as a software as medical device product.

CovidCare is a mobile phone based application designed to assist people to self-monitor their symptoms of COVID-19 during self-isolation and to determine the mental health impacts of COVID-19 and self-isolation.

Upon attendance at the University of Melbourne health service, primary care clinic or dedicated respiratory clinics responsible for administering testing for COVID-19, people can download the app and use the features to self-monitor key respiratory and cardiac vital signs for COVID-19. The app provides guides people about symptoms and when to seek medical assistance and is designed to support people self isolating, and to self-manage COVID-19 at home.

The app also includes screening measures for depression and anxiety to determine the mental health impacts and makes suggestions if people should seek further professional support for their mental health. People will use the CovidCare app until their symptoms resolve or a diagnosis is returned. For people who receive a negative COVID-19 diagnosis, they can continue to use the app while they are in isolation but they may discontinue using the app.

For people who receive positive COVID-19 diagnosis, they will be encouraged to continue using the app for 14 days, or until symptoms resolve. Physical Data is collected daily for days 1 to 4, and twice per day for days 5 to 14 based on current guidelines that indicate that symptoms for COVID-19 can deteriorate from day 5 onward. This data includes:

- Heart Rate
- Respiration Rate
- Temperature
- Breath out
- SpO2 Oxygen Saturation (where an oximeter is available and 0 if unavailable)

If the information entered by the user into CovidCare for physical data is outside a defined normal clinical range a user will be prompted to re-complete their assessment in 2 hours. If user symptoms have deteriorated beyond a pre-determined threshold (calculated over a 72 and 96 hour window - e.g. 3 days allowing for a day of missing data if someone skipped measurements of day 2 or 3), the user will be prompted either to monitor and consider seeking medical advice or to urgently seek medical advice. Where there is evidence of data being outside of healthy ranges, and signifying deterioration, the app will prompt the user to contact their general practitioner, call 000 for emergency care, or attend an emergency department.

Mental Health Data is collected at onboarding/baseline, week 2 post baseline and week 4 post baseline using:

Personal Health Questionnaire (PHQ2) – Measure of Depression.
Generalised Anxiety Disorder (GAD2) – Measure of Anxiety.

Participants will be asked to complete two questions for depression screening and two questions for anxiety screening. Participants who score equal to or more than three on either questionnaire will be recommended to contact a GP to discuss their emotional needs. Scores equal to or more than 3 than typically indicate probable symptoms and the recommendation is for completion a full PHQ9 and GAD7 assessment.

Outcomes
Primary outcome [1] 323726 0
Efficacy will be determined by an audit conducted by a data analyst of the daily vital sign entries to assess appropriateness of values and accuracy of triage outcomes. Statistical evaluations will be completed of threshold ranges to determine accuracy and safety of vital sign monitoring and triage.
Timepoint [1] 323726 0
Data is entered daily from days 1-4 and 2 times per day for days 5-14 post COVID-19 diagnosis. Additional data may be requested to be entered by the CovidCare app if data is beyond pre-determined thresholds and requires verification.
Primary outcome [2] 323944 0
Safety will be determined by evaluating the raw vital sign data entered into the app to ensure that the data has triggered the correct notifications to participants based on the pre-determined thresholds established to identify deterioration warranting further medical advice.

Data will be analysed daily for 14 days
Secondary outcome [1] 382730 0

Sample size
Estimates for the clinical trial sample size for a phase II open label, non-randomised trial to test safety and efficacy were calculated by using the lower end figures of current tests reported by active Australian respiratory clinics. These test rate estimates were gathered from a brief consultation conducted by phone with a sub-set of the currently operating 61/100 respiratory clinics across Australia. Currently data on tests conducted per individual respiratory clinics is not publicly available.

We estimated, based on reported figures from our consultation that, on average, all 61 clinics conducted approximately 150 tests per week. We based our sample size for determining the safety and efficacy of CovidCare for self-monitoring and screening for mental health on the Covid-19 positive test group only (1%). We based our attrition figures on previously reported m-health randomised controlled trials which show attritions ranges from 70-90%.

Using the conservative estimates as a guide with 80% attrition, 200 COVID-19 users will provide sufficient data to establish performance safety of app and to determine efficacy related to self-monitoring. These are estimates of averages that have been calculated as a guide to determine the clinical evaluation time frame and potential sample that will be available to determine safety and efficacy. There will be variability across clinics in terms of numbers of test per week conducted, and numbers will be lower in clinics that have just started compared to those with processes and procedures in place for longer.

If there are 100 respiratory clinics available during the trial life (which is the projected number of total respiratory clinics nationally), the potential total sample size would increase and result in a sample of 504 (70% attrition), 336 (80% attrition) and 168 (90% attrition).

Assessment of performance.

The performance endpoint of safety will be determined by using only the Covid-19 positive group of participants recruited to the trial for validation of the algorithm. This is the group who are the most likely to be a full 14 day use group due to self-isolation requirements, and who might experience deterioration as currently outlined in the negative trend assessments completed by the app.

Performance, safety and efficacy will be determined by evaluating the raw values entered for vital signs and assessing the algorithm thresholds. This includes an analysis of the data to ensure that negative trends of 10% and 20% are sufficiently safe. The full methods for validation will be outlined in the SAP.

Assessment of safety
The safety parameters for CovidCare will be investigated by evaluating the raw values entered by patients into the app for daily readings of vital signs only to determine these are within range of the status groups that the patient received information on. These evaluations will be conducted by the Data Manager for the trial.

Qualitative Substudy.
Responses will be transcribed and subjected to thematic analysis to identify broad themes on the experiences of people isolating with a COVID-19 diagnosis.

Summary
Brief summary
CovidCare provides patients with symptoms and/or a diagnosis of COVID-19 with self-monitoring support during self-isolation. CovidCare is also providing researchers with critical information about emotional needs and the impact on mental health of self-isolation due to Covid-19. The aim of the study is to make sure that CovidCare is safe to use and that it performs accurately. From this study we also hope to better understand the mental health impacts and well-being of people who have received a positive diagnosis for COVID-19
