After researchers rose questions about the study on hydroxychloroquine, a British medical journal called The Lancet, and New England Journal of Medicine issued an Expression of Concern.
The study about the drug found that hydroxychloroquine increased the risk of death in patients with coronavirus. All research relied on a patient experience report from a private database run by a firm named Surgisphere.
The organization said it has details from 1,200 hospitals and other health facilities on six continents on about 100,000 Covid-19 patients.
The study further mentioned that the World Health Organization (WHO) banned its use in a large trial on COVID-19 patients. Similarly, the governments of France, Italy and Belgium have stopped the use of hydroxychloroquine.
Close to 150 doctors recently signed an open letter to the Lancet calling into question the findings of its article and asking for the peer review comments that led the publication to be made public.
They have posed concerns about the unprecedented number of patients involved and their demographic data.
Surgisphere, too, has released a statement that the audit would add greater clarity to its work and further stress the efficiency of its work.
US President Donald Trump said in March that hydroxychloroquine used in combination with antibiotic azithromycin had ‘a real chance to be one of the biggest game changers in medicine history.’
The president said he took the medication himself after two staffers at the White House tested positive for coronavirus.
