Evolving the gay, bisexual and other men who have sex with men time-based deferral to sexual risk screening for all donors: The contribution of Canadian research programmes

Implementation of sexual risk behavior donor screening in Canada

BACKGROUND

The two Canadian blood suppliers, Canadian Blood Services and Héma-Québec, removed the time-based deferral for men who have sex with men and adopted criteria assessing sexual risk behaviors. We report the impact of these changes on the safety and adequacy of the Canadian blood supply.

STUDY DESIGN AND METHODS

Since 2022, all donors are asked if (1) they have had a new partner and (2) more than one sexual partner in the last 3 months. Donors answering yes to either question are asked if they had anal sex in the last 3 months; if yes, they are deferred for 3 months. We followed HIV rates for the 18 months before and 14 (Héma-Québec) or 18 months (Canadian Blood Services) post-implementation and interviewed HIV-positive whole blood donors. We assessed the number and characteristics of whole blood donors answering yes to the two first questions with or without deferral.

RESULTS

There were four HIV-positive donations out of 1,492,355 donations pre-implementation and four out of 1,447,772 post-implementation (0.27/100,000 vs. 0.28/100,000, p = 1.00). Post-implementation, one HIV-positive donor was non-compliant with multiple criteria, no risk factors were identified in the others. 3.2% of donors answered yes to questions (1) and/or (2); 0.17% were deferred for a new partner and/or more than one partner and anal sex. Deferral rates were highest in first time, younger donors, and similar in males and females.

CONCLUSION

Implementation of sexual risk behavior donor screening resulted in unchanged HIV rates to date and a manageable deferral rate.

Improving gay, bisexual and transgender inclusion in blood and plasma donation policies and programmes in Canada: A qualitative study

BACKGROUND AND OBJECTIVES

An increasing number of blood operators around the world, including those in Canada, have removed time-based deferral periods for gay, bisexual and other men who have sex with men and replaced them with sexual behaviour-based questions for all donors. While this marks a significant shift in screening approach, what remains unclear is how members of two-spirit, lesbian, gay, bisexual, transgender and queer (2S/LGBTQ+) communities view blood operators' initiatives to be more inclusive. As such, this study was conducted to assess the awareness of donor screening changes and other initiatives among members of 2S/LGBTQ+ communities and to explore their recommendations for blood operators' work with these communities.

MATERIALS AND METHODS

Semi-structured qualitative interviews (n = 15) were conducted with 2S/LGBTQ+ people across Canada. Data were analysed using open inductive coding methods.

RESULTS

Reported here are the key results on recommendations for blood operators. Three themes were identified from the data: (1) the need for increased communications with 2S/LGBTQ+ communities surrounding changes to donor policies and guidelines; (2) the need for trans-inclusive policy and procedures; and (3) the need for culturally responsive and equity-informed staff training at donor centres.

CONCLUSION

Results suggest that blood operators should consider 2S/LGTBQ+ communities when developing blood and plasma donation policies, screening procedures and staff training. Increased consultation with these communities is desired, and further research specific to the experiences of transgender blood donors is needed.

MSM and blood donation: shifting to individualized risk assessment

Deferring donors at higher risk for transfusion transmissible infections is an important part of ensuring blood safety. The deferral for gay, bisexual, and other men who have sex with men (gbMSM) was implemented in the 1980s in many countries, since they were identified as a high-risk group for AIDS/HIV. With the introduction of increasingly sensitive HIV antibody testing, augmented by nucleic acid testing, the window period for HIV infection-when a donor may be infectious but have negative test results-has shrunk dramatically. In Canada, this has led to progressively shorter deferral periods for gbMSM, decreasing from a permanent deferral for sex with another male since 1977 to a 5-year, 12-month, and eventually 3-month deferral period. These time-based deferrals maintained safety; however, they are seen as stigmatizing by many and still result in the deferral of sexually active gbMSM. More recently, several countries have moved to a donor screening approach based on assessing sexual risk behaviors in all donors. This article outlines research supporting changes in policy, current eligibility screening policies in several countries, and preliminary results postimplementation of new eligibility policies in Canada in September 2022.
