Examining patient characteristics and HIV-related risks among women with syphilis as indicators for pre-exposure prophylaxis in a nurse-led program (PrEP-RN).

Abstract

Current HIV pre-exposure prophylaxis (PrEP) guidelines primarily target men who have sex with men (MSM) as candidates for HIV prevention; however, such recommendations often come at the expense of other ethnic and gender minorities, including women. To address barriers to PrEP care among non-MSM, we developed and implemented the first nurse-led PrEP program in Canada, known as PrEP-RN. As part of PrEP-RN, patients who meet objective indicators of HIV risk are offered a referral for PrEP, regardless of sexual orientation. One such measure is syphilis, which has increased in incidence among various population groups and is known to cause biological vulnerabilities to HIV. To better understand HIV-related risks and assess intentions for PrEP use among women, we undertook an 18-month retrospective review of syphilis diagnoses within this group in Ottawa, Canada. As part of this review, we examined 23 patient files, noting their unique characteristics, socio-behavioural risk factors, and noted barriers to PrEP uptake. While none of the women diagnosed with syphilis were diagnosed with HIV, the findings raise some important considerations to facilitate opportunities for HIV prevention among non-MSM, which must take into consideration individual risk practices, sexual health histories, and population groups.
