New paper (Chandra): Scaling Up Event-Driven PrEP among MSM
New paper led by Christina Chandra in the Journal of Acquired Immune Deficiency Syndromes: Modeling the Potential Impact of Scaling Up Event-Driven PrEP among Gay, Bisexual, and Other Men Who Have Sex with Men. A network model simulated HIV transmission among 100,000 men who have sex with men in Atlanta over 10 years, adding event-driven PrEP on the 2-1-1 schedule. Against a baseline of daily PrEP only, raising event-driven initiation until overall PrEP use nearly doubled (28.5% versus 16.1%) averted 18.3% of infections. Extending eligibility to any sexually active man averted 15.8%. Targeting men who discontinued daily PrEP with low adherence yielded no population-level improvement, and raising initiation mattered more than improving adherence.
