Clinical Trend of the Week (May 6 - 12): Blood Sex

This week's top search term surged in popularity due to a new study that contradicted a previous study. A study published online in JAMA Internal Medicine found that blood donor sex and age are not associated with recipient survival. Thus, sex and age are not relevant to donated blood allocation. The Scandinavian study examined almost 1 million transfusions, and the findings contradicted a 2016 Canadian study, which had concluded that blood from young or female donors was significantly associated with an increased risk for death among transfusion recipients. The Scandinavian researchers were unable to replicate the findings of the Canadian study, instead finding the association was eliminated. The disparate results of these studies prompted searches on the connection between blood donations and donor sex and age, a subject likely to receive continued scrutiny.
