as an emergency physician, i have seen donated blood save countless lives. trauma, cancer and transplant patients all require blood, sometimes hundreds of units in a single hospital stay. my own record, working in a trauma intensive care unit in residency, was 202 units, or about 100 litres, of blood products poured into a single patient.
canada’s hospitals collectively transfuse nearly 1 million units of blood each year to patients, all of it donated by canadians. but despite our generous collective effort, shortages abound. according to canadian blood services, the agency responsible for canada’s blood supply, only four per cent of canadians roll up their sleeves to donate each year.
after the tainted-blood scandals of the 1980s, responsibility for canada’s blood supply was transferred from the red cross society to canadian blood services. legitimate fears about hiv and hepatitis existed back then, as they do now. but it’s not the 1980s anymore; hiv is no longer the mysterious “gay man’s disease” it once was and screening techniques have advanced significantly. yet the basic premise of the ban on gay men donating blood remains the same – that in being gay, we are, collectively, too risky a group to tap into.
of the u.k.’s plans to scrap the three-month window for gay men, health secretary matt hancock said “this landmark change to blood donation is safe and it will allow many more people, who have previously been excluded by donor selection criteria, to take the opportunity to help save lives.”
but the change does more than increase the depth of the blood donor pool. it actually makes the blood collected even safer. by applying individualized risk criteria to all people, not just gay men, the new rules will exclude heterosexual people who engage in behaviours shown to be high risk for contracting blood-borne viruses like hiv and hepatitis, such as anal sex outside of a monogamous relationship.
