Noncompliance to blood donor selection criteria by men who have sex with men - Complidon 2017, France

Background and objectives: In France, blood donation deferral for men who have sex with men (MSM) was reduced from permanent to 12 months in July 2016. Assessing noncompliance (rate and reasons) with this criterion is important to maintain a high level of viral safety in blood products.

Materials and methods: An anonymous online survey (Complidon) of a sample of blood donors was conducted in 2017. Data were post-stratified to be representative of all those who donated blood between July 2016 and December 2017. A multivariable analysis was performed to assess factors associated with noncompliance.

Results: Among male donors, 0·73% [95% CI: 0·63-0·83] reported having sex with men in the 12 months preceding their donation. Factors associated with noncompliance were as follows: young age, a low educational level, concerns about privacy, and better knowledge of donor selection criteria and the window period than compliant men. More than half of noncompliant MSM donors (57·6% [95% CI: 50·6-64·3]) felt that sexual orientation should not be a criterion for donation, 47·2% [95% CI: 40·4-54·0] did not disclose their male-to-male sexual relations in order to avoid being excluded from donating, 40·5% [95% CI: 34·0-47·4] reported using condoms and 21·8% [95% CI: 16·7-27·9] had the same male partner for at least 12 months.

Conclusion: Complidon showed that compliance with blood donation criteria in MSM was high, but not optimal, especially among younger men. HIV residual risk did not increase after the implementation of 12-month deferral. Data from Complidon helped French policymakers to assess the additional HIV risk posed by increased access to blood donation for MSM.
