The use of Hydroxychloroquine as a possible treatment has become the focus of emotional and political controversy. The best use or non-use should just be a medical and scientific matter based on actual medical and scientific studies and data.
In a large-scale retrospective analysis of 2,541 patients hospitalized between March 10 and May 2, 2020 across the system's six hospitals, the study found 13% of those treated with hydroxychloroquine alone died compared to 26.4% not treated with hydroxychloroquine. None of the patients had documented serious heart abnormalities; however, patients were monitored for a heart condition routinely pointed to as a reason to avoid the drug as a treatment for COVID-19.
The study seems to say that deaths are reduced by half if patients who are given treatment early. But it has to be patients without serious heart problems. They did not completely randomize the patients. It is not for all patients. So need to randomize the subset and control for steroids.
