Tracking Sexually Transmitted Infections among Cisgender Women Seeking Care at an Urban Safety-Net Hospital to Identify HIV Pre-Exposure Prophylaxis Candidates.

Cisgender women are underserved by current HIV prevention efforts, and substantial gender disparities persist in pre-exposure prophylaxis (PrEP) use. Recent diagnoses with a bacterial sexually transmitted infection (STI) are objective, readily available indicators of PrEP-eligibility that could be used to improve PrEP prescribing for cisgender women. To better understand missed opportunities for prescribing, we examined the prevalence and correlates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) diagnoses among cisgender women seeking care at a New York City obstetrics and gynecology (Ob/Gyn) clinic, along with the number of PrEP prescriptions provided post-STI diagnosis. A cross-sectional, retrospective review of electronic health record data was conducted for all HIV-negative cisgender women tested for CT and/or NG at the clinic between September 1, 2021 and September 19, 2022. Counts and prevalence for CT and NG infection were calculated, and multivariable log-binomial regression was used to examine associated factors. Among 7593 cisgender women receiving CT/NG testing during the study period, 186 had ≥ 1 CT infection (prevalence: 2.45%) and 18 had ≥ 1 NG infection (prevalence: 0.24%). In a multivariable model, CT/NG infection was significantly associated with age, having Spanish as a primary language, and a marital status of divorced, widowed, or separated. No cisgender women who received CT or NG diagnoses were prescribed PrEP during the study period. These findings highlight how opportunities to prescribe PrEP to cisgender women continue to be missed, even with readily available indicators for PrEP eligibility. More effective strategies are needed to promote PrEP prescribing among diverse populations of cisgender women, particularly in Ob/Gyn settings.
