Development and Evaluation of a Novel Algorithm to Identify Doxy-PEP Users at a Large Healthcare System in the Bronx, New York

Abstract Doxy-PEP is used to prevent chlamydia, syphilis and gonorrhea infections in sexual and gender minority men and transgender women. We describe a systematic process for developing algorithms that allow for the identification of doxy-PEP prescriptions. Using an identified algorithm will allow for improved monitoring of implementation and effectiveness.
