Brief summary
There is surge in COVID infected patients in New York City with a shortage of hospital beds, ICU beds and ventilators. Strategies to reduce the need for all of the above are immediately needed. Further, few interventions are targeted in COVID infected patients early in the course of their disease and especially in the community/home settings. Respiratory decompensation appears to occur later in the disease process (i.e. 7-10 days after becoming symptomatic) therefore many patients are sent home from the Emergency Room and they subsequently decompensate later at home. Some patients die at home and others are returning to the Emergency Room with hypoxemic respiratory failure. There is no treatment offered to this population of patients, i.e. COVID suspected or confirmed and with respiratory symptoms or abnormal chest x-ray at the time of presentation. Based on experience across the globe, these patients are likely to worsen at home. The study team therefore proposes a prospective, single-center, parallel group, open-label, randomized clinical trial to assess the efficacy of fixed low continuous positive airway pressure therapy (CPAP) (FDA approved and often used for treatment of sleep apnea) in COVID confirmed or suspected patients with abnormal chest x-ray or respiratory symptoms who do not require hospital admission and are discharged home from the emergency room.
Detailed description
The study team proposes a randomized controlled trial of CPAP (n=100) vs. control (n=100) in COVID-19 suspected or confirmed patients with pneumonia or respiratory illness. The overarching aim of this proposal is to determine if early use of CPAP at home will reduce hypoxemic events or reduce the need for hospital admission or death in COVID-19 suspected or confirmed patients. The study team will include adult patients (age\>18) who live alone or have more than one bedroom at home, with serologically confirmed or suspected COVID-19 infection, who have one or more of the following: fever (\>38ºC), sore throat, myalgia or flu-like illness AND have one or more of the following additional symptom or diagnostic criteria: abnormal chest x-ray, new onset cough, mild hypoxemia at rest (saturation less than 96%), abnormal lung exam, chest tightness or shortness of breath AND who are without need for hospital admission. Patients with preexisting pulmonary diseases such as advanced COPD, advanced parenchymal lung disease, history of pneumothorax etc. will be excluded. Participants in both arms will be shipped a pulse oximeter to monitor oxygen saturation and a disposable home sleep apnea monitor (WatchPAT) to track blood oxygen level continuously for 12 hours with data feed into a cloud based platform. Additionally, 100 patients will be randomized to receive CPAP at fixed pressure (8-10cm H20) for 72 hours continuously (except for daily activities such as eating, personal activities and breaks for ambulation etc). The CPAP pressure will be adjusted based on patient's comfort but will not deviate from the range of 8-10cm. While the study protocol will end at 72 hours, patients who wish to continue CPAP will be allowed to do so for symptomatic benefit up to 7 days from randomization. All CPAP recipients will be given a full-face mask and will be asked to stay in quarantine for the duration of the protocol to avoid risk of infecting family members with aerosol (separate consent to be obtained from household members who are elderly or with comorbidities.) The study team hypothesizes that early low-grade fixed CPAP in COVID infected patients who have respiratory abnormalities will reduce hypoxemic events and decrease the risk of subsequent hospitalization or death in 14 days from randomization. The study will also address whether use of CPAP in the home increases the risk of infecting household family members.

Intervention model description
This is a prospective, single-center, parallel group, open-label, randomized clinical trial, where the study team will investigate the efficacy of continuous positive airway pressure therapy (CPAP) in COVID suspected or confirmed patients who are sent home from the emergency room with mild pneumonia or respiratory illness but who do not require hospital admission. The study team proposes a randomized controlled trial of CPAP (n=100) vs. control (n=100) in COVID-19 suspected or confirmed patients with pneumonia or respiratory illness.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants Who Met the Efficacy Endpoint | 14 days | Number of participants who met the efficacy endpoint within 14 days. The efficacy endpoint is meeting any of the following: All-cause mortality within 14 days of randomization, hospital admission (including ED visit) within 14 days of randomization, oxygen saturation less than 90 during the 72-hour observation period from randomization, absolute reduction in oxygen saturation of more than 4% during the 72-hour observation period from randomization. If a participant meets any of the events noted in the composite endpoint, it is counted as a worse outcome. The composite endpoints were selected based on available covid-related information at the time of the study design. This study was conducted to determine measures that alleviated hospital burden, allowing patients to be managed at home. Oxygen-related endpoints measure improvement in a home setting and contribute to a higher number of events in the composite outcomes, to provide enough power to measure efficacy in a small trial. |

The time frame is a change between the baseline COPD score at the time of enrollment and the last COPD score recorded within the following 14 days. The CCQ is a 10-item instrument questionnaire, with each question scored on a scale of 0 to 6. Thus, the full scale is 0 to 60, with higher score indicating lower health status. A negative value indicates that their score improved. A decrease in CCQ indicates improvement, Last Observation Carried Forward (LOCF) applied. |
