Objective: We aimed to identify preferences for PrEP care among diverse gay, bisexual, and other men who have sex with men (BLGBM) in the US with discrete choice experiment (DCE).

Design: We conducted two DCEs to elicit care delivery preferences for Starting and Continuing PrEP among 16-49 year-old HIV negative GBM not using PrEP from across the United States. DCEs assessed preferences for care options including location, formulation (pills, injectable), lab testing, and costs.
