Blood thinners reduce Covid-related mortality, hospitalisation: study

October 04, 2021 15:43

COVID-19 patients who use blood thinners may have a nearly 50 per cent reduced risk of death and a 43 per cent lower risk of hospitalisation, according to a study published in Lancet's EClinical Medicine journal.

The research was conducted on 6,195 patients over the age of 18 who were diagnosed with COVID-19 from March 4 to August 27, 2020 in 12 hospitals and 60 clinics in the US.

The researchers from the University of Minnesota, US, and Basel University in Switzerland analysed the relationship between 90-day anticoagulation therapy among out-patients before COVID-19 diagnosis and the risk for hospitalisation and mortality.

The researchers also evaluated the association between anticoagulation therapy, which is used to prevent blood clots, and mortality risk among admitted patients.

The study found that patients on blood thinners before contracting COVID-19 were 43 per cent less likely to be admitted to hospital, despite being older and having more chronic medical conditions than their peers.

Blood thinners, regardless of being used before being infected with COVID-19 or started when admitted to the hospital for treatment of the viral disease, reduce deaths by almost half, they added.
