No improvement in death rate for COVID-19 patients who received hydroxychloroquine : Research

A research team led by investigators from Brigham and Women's Hospital has evaluated real-world evidence related to outcomes for COVID-19 patients who were treated with hydroxychloroquine or chloroquine analogues (with or without a macrolide). Investigators found no evidence that either drug regimen reduced the death rate among patients. Patients treated with hydroxychloroquine or chloroquine regimens were far more likely to experience abnormal, rapid heart rhythms (known as ventricular arrhythmias) than their counterparts who had not received the drugs. The team's findings are published in The Lancet.
