Background: Disease intervention specialists (DIS) provide partner services for sexually transmitted infections (STIs). We assessed an expansion of DIS services for clients with HIV and/or syphilis, and contacts within their social and sexual networks., Methods: Black and Latinx cisgender men and transgender women who have sex with men diagnosed with HIV and/or syphilis in 4 urban North Carolina counties were referred to designated DIS, who were trained to recruit clients as "seeds" for chain-referral sampling of sociosexual network "peers." All received HIV/STI testing and care; referrals for preexposure prophylaxis (PrEP) and social, behavioral, and non-STI medical services were offered. Participants completed baseline, 1-month, and 3-month computerized surveys., Results: Of 213 cases referred to DIS from May 2018 to February 2020, 42 seeds (25 with syphilis, 17 with HIV) and 50 peers participated. Median age was 27 years; 93% were Black and 86% were cisgender men. Most peers came from seeds' social networks: 66% were friends, 20% were relatives, and 38% were cisgender women. Incomes were low, 41% were uninsured, and 10% experienced recent homelessness. More seeds than peers had baseline PrEP awareness; attitudes were favorable, but utilization was poor. Thirty-seven participants were referred for PrEP 50 times; 17 (46%) accessed PrEP by month 3. Thirty-nine participants received 129 non-PrEP referrals, most commonly for housing assistance, primary care, Medicaid navigation, and food insecurity., Conclusions: Chain-referral sampling from partner services clients allowed DIS to access persons with significant medical and social service needs, demonstrating that DIS can support marginalized communities beyond STI intervention., Competing Interests: Conflict of Interest and Sources of Funding: C.B.H. supervised local research activities for a clinical trial of preexposure prophylaxis sponsored by Gilead Sciences. A.C.S. received a Frontlines of Communities of the United States grant from Gilead Sciences and royalties from UpToDate., (Copyright © 2021 American Sexually Transmitted Diseases Association.

Background: Expanding access to HIV preexposure prophylaxis (PrEP) could help reduce rates of HIV infection in the United States. This study characterizes activities and barriers to PrEP implementation at local health departments (LHDs) in North Carolina (NC), which contains a large rural population., Methods: In May 2016, a web-based survey was distributed to health directors of all county and district health departments in NC to assess PrEP-related activities, perceived barriers to PrEP implementation, and desired PrEP-related resources., Results: Of 85 LHDs in NC, 56 (66%) responded to the survey. Of these, 2 (4%) reported PrEP prescribing and 7 (13%) externally referred for PrEP services. Among the 54 departments not prescribing PrEP, the most frequently cited reasons were cost concerns (n = 25, 46%), lack of formal prescribing protocols (n = 21, 39%), and belief that PrEP would be better managed at primary care or specialty clinics (n = 19, 35%). Among the 47 departments not prescribing or referring clients for PrEP, the most frequently cited reasons for the lack of PrEP referral were the absence of local PrEP providers (n = 29, 62%), lack of PrEP knowledge among staff (n = 13, 28%), and perceived lack of PrEP candidates (n = 12, 26%). The most frequently requested PrEP-related resources included training to help identify PrEP candidates (n = 39, 70%) and training on PrEP prescribing and management (n = 38, 68%)., Conclusions: PrEP prescribing and referral among LHDs in NC remains extremely limited. Increased PrEP-related training and support for LHD-based providers could enhance PrEP access, especially in rural and underserved areas.
