Staff and Providers' Perceptions of Patients' PrEP Candidacy, Acceptability, and Adherence in Methadone Clinic...

People who use drugs and patients in substance use treatment may be placed at high risk for HIV due to mixing sex and drugs, potential engagement in sex work, and injection drug use. However, pre-exposure prophylaxis (PrEP) adoption among these populations remains low. Methadone clinics, a main point of contact with the healthcare system for this population, are a missed opportunity to offer biomedical HIV prevention. Understanding provider and staff perceptions of patients' PrEP-related candidacy, acceptability, and adherence is a critical first step to informing PrEP implementation in substance use treatment settings.

Thirty semistructured interviews were conducted at 2 methadone clinics in Northern New Jersey between January and April 2019. Participants included methadone counselors, medical providers, front desk staff, intake coordinators, and other clinic staff members.

Three major themes were identified: (1) provider and staff's perceptions of who would benefit most from PrEP, (2) perceptions of patients' acceptability of PrEP, and (3) perceptions of patients' ability to take a pill every day. Broadly, staff perceived younger patients to be better PrEP candidates than older patients, expressed cautious optimism that PrEP would be acceptable to their patient populations, and were mixed in terms of their perceptions of patients' ability to adhere to PrEP. Notably, staff largely did not mention patients who inject drugs as potential PrEP candidates, suggesting a missed opportunity.

To promote PrEP implementation in methadone clinics, staff and providers should receive training around screening for PrEP eligibility in order to maximize the benefits of PrEP for various subpopulations, especially those who inject. Importantly, discussions around sexual behavior and injection drug use must be approached in an open, non-stigmatizing manner. These findings can be used to inform future interventions to integrate PrEP services into substance use treatment settings.
