- Impact of hydroxychloroquine in hospitalized patients with COVID-19 and risk factors for severe/critical disease. [ Time Frame: 30 Days ]The impact will be evaluated by comparing rates of a composite primary outcome in patients randomized to hydroxychloroquine versus those randomized to placebo. The composite outcome includes progression to severe/critical disease or death (including withdrawal of care/hospice transfer). Progression to severe/critical disease is defined by requiring oxygen delivery via high flow nasal cannula, non-rebreather mask, bipap, or transfer to intensive care (ICU) or intermediate care units (IMCU) due to COVID-19-related complications.
- Hospital length of stay [ Time Frame: 30 Days ]
- 30-Day Mortality [ Time Frame: 30 Days ]
- Resolution of Symptoms [ Time Frame: 14 Days ]Resolution of symptoms will be assessed using standard medical interview procedures with the subject and review of the medical records.
- Incidence of QTc >500ms after initiation of therapy [ Time Frame: 30 Days ]
- Incidence of discontinuation of therapy [ Time Frame: 30 Days ]
