Optimizing access to PrEP based on MSM preferences: results of a discrete choice experiment.

Our data suggest that PrEP uptake will be maximized by making daily PrEP affordable to MSM and streamlining PrEP consultation visits for young MSM. Young MSM should be prioritized for injectable PrEP when it becomes available. A successful PrEP program will spend resources on removing structural barriers to PrEP access and educating MSM of color, and will emphasize protection of privacy to maximize uptake among rural/suburban MSM.
