Brief Summary

The rapid development of safe and effective COVID-19 treatment is a global health priority. Numerous studies evaluating therapies for this disease are currently underway, but the majority of these are in hospitalized patients with severe illness. Consequently, there is an urgent need to identify therapies that prevent mild COVID-19 cases in the community from becoming more severe. "Proning" or lying face down in bed has been shown to improve breathing and oxygen levels in COVID-19 patients, reducing the need for breathing tubes and ventilators and increasing survival. The current study will investigate whether proning and repositioning (lying on one's side or sitting up) can prevent mild cases of COVID-19 from becoming more severe resulting in fewer hospitalizations and death. A randomized controlled trial will be used to reduce the risk of bias when testing this intervention. Unvaccinated or partially vaccinated adult patients with a positive COVID-19 test willing to participate and well enough to be treated outside the hospital will be randomly assigned to one of two groups: a home-proning intervention group with instructions and daily reminders to prone and reposition during the day and at night, and a standard care group. Our goal is to assess whether home-proning/repositioning leads to fewer hospitalizations and death when compared with standard care. We'll also compare recovery time, use of antibiotics and follow up emergency department visits between these two groups. The current pilot study will assess the feasibility of a larger investigation or "main trial", meaning it will be small scale test of methods and procedures to be used on a larger scale.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Composite of hospitalization and all cause mortality	Up to 28 days post-randomization	The primary outcome is a composite of hospital admission and all-cause mortality. This will be ascertained using telephone follow up and deterministic record linkage performed by the Institute for Clinical Evaluative Sciences (ICES) using their Discharge Abstract Database (DAD).

Secondary Outcome Measures

Name	Time	Method
Use of antibiotics for respiratory illness	Up to 28 days post-randomization
Hospitalization	Up to 28 days post-randomization
All cause mortality	Up to 28 days post-randomization
Follow up emergency department assessment without hospital admission	Up to 28 days post-randomization	Number of subsequent emergency department visits by study participants that relate to the initial COVID-19 presentation but do not result in hospital admission
Time to functional recovery in days	Up to 28 days post-randomization	Defined as: resolution of fever for 48 hours, significant symptom reduction and ability to perform most daily activities or return to work, if applicable, for two consecutive days.
