BACKGROUND: The Transfusion-Transmissible Infections Monitoring System (TTIMS) combines data from four US blood collection organizations including approximately 60% of all donations to monitor demographic and temporal trends in infectious disease markers and policy impacts. STUDY DESIGN AND METHODS: Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) consensus-positive definitions combined serology and nucleic acid testing results. These along with donor and donation characteristics were assembled into a single data set. Overall donation prevalence and demographic subsets were compared pre- and post-implementation of the 2015 change in men who have sex with men (MSM) deferral policy, among other prevalence comparisons. RESULTS: From October 2015 to September 2019, there were 712 HIV-, 1735 HBV-, and 5217 HCV-positive samples identified from approximately 27.5 million donations (>9.4 million donors). Prevalences per 100 000 donations were 2.6 (HIV), 6.3 (HBV), and 19.0 (HCV), and the highest for all three agents were in donations from first-time male donors. Two slight but significant increases in HIV prevalence were observed, both for comparisons of Year 1 (pre-MSM policy change) versus Year 4 (post-MSM policy change) for first-time males and first-time females; in contrast, similar comparisons demonstrated decreases in HCV prevalence (all donors and general trends for males and females). Except for HIV, prevalence increased with age; for all agents, prevalence was markedly higher in the south. CONCLUSIONS: No major trends were observed over 4 years covering the MSM policy change from indefinite to a 12-month deferral, but ongoing monitoring is warranted. Demographic trends are consistent with those observed in other donor studies and community trends.
