Evidence-Based Policy and Practice Leads to Changes in the Criteria for MSM to Donate Blood.

On November 7, 2011, the permanent deferral from blood donation of men who have sex with men (MSM) changed in England, Scotland and Wales, to a 12-month deferral since last relevant sexual contact. This change was made following an evidence-based policy review by the Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO). The review concluded that the available evidence supported the introduction of a 12-month fixed period deferral and that the risks associated with a 12-month deferral of MSM were equivalent to a permanent deferral. The permanent deferral for MSM was introduced in 1985 in response to the spread of acquired immunodeficiency syndrome (AIDS) caused by HIV. The change was supported by new data on the level of compliance with the permanent deferral, advances in the testing and processing of donated blood, changes in the epidemiology of sexually transmitted infections (STIs) and improved scientific knowledge. This review discusses how the decision to change the deferral period was reached and highlights some of the remaining issues relating to this contentious matter.
