The purpose of this research is to test whether a new medication called bamlanivimab is safe and effective at reducing the need for hospitalization due to COVID-19.

The study aims to examine the effectiveness of adding bamlanivimab provided by COVID-19 Clinics to standard of care on the incidence of hospitalization for high-risk patients infected with SARS-CoV2. Furthermore, we aim to test the effect on the following secondary outcomes: mortality and health-related quality of life and patients' satisfaction with care. We will also assess the recruitment rate from the three primary strategies for rapid identification and consent of eligible patients. The data from this study will inform clinical decisions about the use of bamlanivimab in high risk COVID-19 patients and the operational requirements necessary for research in passive immunity therapeutics.
