Abstract

Background
Black women comprise 55% and 46% of new HIV diagnoses among cisgender and transgender women in the United States, respectively.1 Research has demonstrated the superiority of long-acting cabotegravir (CAB LA) for PrEP in reducing the risk of sexually acquired HIV-1 infection compared to oral PrEP (TDF-FTC). EBONI is a phase 4 effectiveness-implementation hybrid study focused on evaluating implementation of CAB LA delivery to Black cisgender and transgender women in US Ending the HIV Epidemic (EHE) jurisdictions. Results from the baseline survey of Staff Study Participants (SSPs) are presented here.

Methods
SSPs (N=65) from 14 clinics completed surveys with questions pertaining to their clinic characteristics, perceptions of populations appropriate for CAB LA, and their perceived appropriateness of CAB LA for Black women as measured by the Intervention Appropriateness Measure (IAM). The IAM uses a 5-point rating scale (1=completely disagree to 5=completely agree). One designated SSP for each clinic completed a questionnaire to assess use of PrEP at the clinic level.

Results
SSP and clinic-level characteristics are described in Tables 1 and 2. Most clinics were in the South (71.4%) and were private practice (36.4%), FQHCs (18.2%), or community-based organizations (18.2%). A total of 225 Black women across all clinics used any kind of PrEP and 69 received at least one injection of CAB LA at baseline. Most SSPs (86.2%) reported patients asked about CAB LA in their clinic.
Overall, SSPs perceived Black women in their clinic as appropriate for CAB LA (IAM Mean Score=4.6). Sixty-six percent of SSPs reported there were individuals with specific demographics more appropriate for CAB LA. Of these, lesbian women, people older than 50 years of age, and heterosexual men were rated relatively lower than other demographics as appropriate by SSPs (Table 3). Having a partner living with HIV, condomless sex, and having multiple sexual partners were rated as behaviors most appropriate for CAB LA.

Conclusion
Healthcare staff reported high levels of appropriateness of CAB LA for Black women and ranked populations and behaviors traditionally associated with PrEP as most appropriate for CAB LA. Better tools are needed to support SSPs in identifying individuals who could benefit from CAB LA.
