Health Service- and Provider-Level Factors Influencing Engagement in HIV Pre-Exposure Prophylaxis Care Among Male Sex Workers.

Multilevel barriers to pre-exposure prophylaxis (PrEP) care among male sex workers (MSW) include aspects of interactions with health services and providers. We examined relationships between health service- and provider-level factors and PrEP care among MSW. Between 2017 and 2019, we enrolled 111 MSW in the Northeast United States who were not on PrEP, but expressed interest in potentially using PrEP, in a behavioral intervention to promote PrEP uptake and adherence. Using baseline data, we examined whether having a primary care provider, past year frequency of medical visits, comfort discussing sexual practices with providers, and transportation difficulties to accessing general health care were associated with PrEP use self-efficacy, anticipated barriers to PrEP uptake, adherence, and retention (linear regression), and intention to initiate PrEP (logistic regression). Models adjusted for age, race/ethnicity, sexual identity, education, and income. Participants' mean age was 34.2 [standard deviation (SD) = 8.5], and 47% were non-White. Three-quarters (76%) intended to initiate PrEP within the next month. Comfort discussing sexual practices with providers was associated with PrEP use self-efficacy (b = 0.41, p = 0.008). Comfort discussing sexual practices with providers was negatively associated with anticipated barriers to PrEP uptake (b = -0.29, p = 0.006). Transportation difficulties to accessing general health care were associated with barriers to PrEP uptake (b = 0.30, p = 0.007) and barriers to PrEP adherence and retention (b = 0.57, p < 0.001). No health service- and provider-level characteristics were associated with intention to initiate PrEP. PrEP programs targeting MSW may benefit from interventions to foster communication between MSW and providers about sexual practices and should consider structural barriers to accessing care, including lack of access to transportation.
