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.
CONCLUSIONS: Implementation of sexual risk behavior donor screening resulted in unchanged HIV rates to date and a manageable deferral rate.
方法:自2022年以来,所有捐献者都被询问是否(1)他们有一个新伴侣和(2)在过去3个月中有一个以上的性伴侣。对任何一个问题回答“是”的捐赠者被问及他们在过去3个月中是否有过肛交;如果是,他们被推迟了三个月。我们跟踪了实施前18个月和实施后14个月(Héma-Québec)或18个月(加拿大血液服务)的艾滋病毒感染率,并采访了艾滋病毒阳性的全血献血者。我们评估了全血献血者的数量和特征,这些献血者对前两个问题有或没有推迟回答。
结果:在实施前的1,492,355捐款中有4例HIV阳性捐款,在实施后的1,447,772捐款中有4例HIV阳性捐款(0.27/100,000vs.0.28/100,000,p=1.00)。实施后,一名HIV阳性捐赠者不符合多个标准,未发现其他危险因素.3.2%的捐助者对问题(1)和/或(2)回答是;0.17%的人因新伴侣和/或多个伴侣和肛交而被推迟。延期率首次最高,年轻的捐赠者,男性和女性相似。
结论:实施性风险行为供者筛查导致迄今为止的HIV感染率和可控的延迟率不变。
