July 6, 2020 – NOTE, since this study was reported, other evidence as shown no benefit for hydroxychloroquine in treating or preventing COVID-19.
A study published in the International Journal of Infectious Diseases by Henry Ford Health System found that treatment with hydroxychloroquine significantly lowered the rate of deaths among patients hospitalized with COVID-19.
The analysis of more than 2,500 patients across the six hospitals in the Henry Ford Health System found that 13 percent of those who received hydroxychloruqine alone died compared with 26.5 percent of those who were not treated with hydroxychloroquine at all. Of those given hydroxychloroquine plus the antibiotic azithromycin, 20.1 percent and 22.4 percent of those who received just azithromycin died.
None of the patients had a heart condition in their medical records, but all were monitored for effects of hydroxychloroquine on their heart.
Study authors concluded that treatment with hydroxychloroquine alone and in combination with azithromycin was associated with reduction in COVID-19 associated mortality.
