Doxycycline post-exposure prophylaxis for preventing bacterial sexually transmitted infections (STIs): Are clinical providers supportive?

Background: Bacterial sexually transmitted infections (STIs) continue to increase in the United States. Despite evidence of the effectiveness of doxycycline post-exposure prophylaxis (Doxy-PEP) to prevent STIs, little is known about providers' attitudes and willingness to implement Doxy-PEP.

Methods: An online questionnaire was sent to 575 clinical providers in New York State in September 2022.

Results: Ninety-one eligible individuals responded. Most providers served men who have sex with men (MSM) (84%); reported willingness to recommend Doxy-PEP (98%, 77%, and 67% for chlamydia, syphilis, and gonorrhea, respectively); preferred Doxy-PEP administration for MSM and transgender populations; believed recurring bacterial STIs (88%) and reported condomless sex (85%) were the most important characteristics to consider for recommending Doxy-PEP; and were concerned about antibiotic resistance (90%) (primarily for Neisseria gonorrhoeae). Insurance costs were the most perceived community-associated barriers (35%). There were no significant differences in providers' recommendations towards Doxy-PEP use when comparing clinicians' years of experience, regions, or professional titles.

Conclusions: Study results suggest high willingness and support for implementing Doxy-PEP. As this survey was administered prior to national guidelines on the use of Doxy-PEP, these data can be used as a baseline to compare to studies conducted after their release to formulate appropriate messages for providers to improve implementation.
