Background: The predominant mode of transmission of human immunodeficiency virus (HIV) in Europe is male-to-male transmission. Men who have sex with men (MSM) are deferred from donating blood in many countries, but nevertheless do donate blood. Based on data from 34 countries, we estimated the proportion of MSM screened for HIV in the context of a blood donation and identified individual factors associated with this HIV screening in order to propose possible public health interventions., Materials and Methods: In 2010, the first European MSM Internet Survey (EMIS) collected self-reported data on HIV testing from >180,000 MSM in 38 European countries. Using logistic regression, demographic and behavioural factors associated with screening for HIV in blood establishments were identified. Stratified by European sub-region, we analysed the proportion of MSM screening in blood establishments by time elapsed since last negative HIV test., Results: Donor eligibility criteria for MSM vary across Europe with most countries using permanent deferral. The Western region had the lowest (2%) proportion of MSM screened in blood establishments and the Northeastern region had the highest (14%). Being <25 years old, not disclosing sexual attraction to men, never having had anal intercourse with a man, having a female partner, living in a rural area, and certain European sub-regions or countries of residence increased the likelihood of being screened in blood establishments., Discussion: In spite of deferral policies, MSM are screened for HIV in the context of blood donations. Gay-friendly testing services are rare in rural areas, and young men might be reluctant to disclose their sexual orientation. Recent developments, such as home sampling, might offer new testing possibilities for those not reached by established services yet wishing to know their HIV status. Donor selection procedures should be improved. Both interventions might help to further reduce the risk of transfusion-transmitted infections.

Background: Potential risks for transfusion-transmissible infections are identified by donor history questionnaires (DHQs), and donors with higher risks are deferred from donation. We assessed to which extent the currently used DHQs support the identification of infections among blood donors. Methods: Between 2006 and 2013, we analyzed data from notified HIV and HCV cases in the general population and positive blood donors in Germany. Logistic regressions were used to identify relevant infection risks. We estimated the possible effect of improved capture of risk factors for donor selection by calculation of population attributable fractions (PAF). Results: Risky sexual contacts - MSM as well as heterosexual contacts - were the most prominent infection risks among HIV-infected donors. Whereas MSM contacts were significantly less reported by donors than by cases from the general population, 58% of donors disclosed heterosexual risks compared to 26% of notified cases. The complete identification of heterosexual risk contacts might prevent acceptance of 53% of HIV-infected donors. HCV-infected donors were more likely to report heterosexual exposure, imprisonment, and piercing/tattoo than notified HCV cases. Improved recording of piercing/tattoo could prevent acceptance of 16% of HCV-infected donors. Conclusion: Donor selection should be improved with special attention to the identification of (hetero)sexual risk factors, invasive procedures (piercing/tattoo and imprisonment) applying well-designed DHQs, effective donor education, and confidential environment in all steps of the selection process.

Background: We assessed the effect of the uniform donor questionnaire (UDQ) on deferral rates in first-time and repeat donors. We focused on the introduced question about unprotected sexual contact with a new partner. Another goal was a stratified comparison of the deferral rates of the donor questionnaire (DQ) and UDQ. Methods: Data on donors and deferrals using the DQ and UDQ were collected at four blood establishments. The comparison included a 2-year period by questionnaire version. For the comparison of the questionnaires, an adjusted multinomial logistic regression was performed. Results: The analysis included 260,848 donations. First-time (FTD) and repeat donations (RD) showed higher deferral rates with the UDQ (FTD +5.4%, RD +1.4%). Deferral due to a new partner was 3.0% in firsttime and 0.4% in repeat donors. The majority of these occurred in the youngest age groups. The most frequent deferral criterion was 'disease' (5.1%). Conclusion: The regression revealed stronger predictors for deferral than the questionnaire version. Especially younger age carried a higher and independent risk for deferral. The additional deferrals of mainly young first-time donors due to a new sexual partner may identify those donors with potential heterosexual risk behavior who would otherwise not be identified.
