Understanding patient motivations for HIV pre-exposure prophylaxis initiation and adherence.

Consistent dosing of tenofovir/emtricitabine-based HIV pre-exposure prophylaxis (PrEP) can reduce HIV infection risk by up to 92%. However, clinical trials have shown low PrEP adherence (34-71%), resulting in reduced effectiveness. To improve PrEP's effectiveness, adherence to a daily PrEP regimen is essential. This report explores patients' patterns of PrEP initiation and use and their PrEP-related perceptions to provide greater understanding of patient motivations for beginning and adhering to PrEP. At two urban primary care clinics, individual coaching sessions that included semistructured interviews were offered to 10 PrEP patients. Regarding PrEP initiation, 30% of patients were advised to use PrEP by their nurse practitioners (NPs), while the remaining patients requested PrEP themselves. Before they initiated PrEP, all patients were familiar with it through social contacts or internet-based research. Patients' PrEP-related perceptions were identified, including perceived pros and cons of PrEP use, and degrees of PrEP knowledge, uncertainty, and fear. Primary care NPs should take detailed sexual histories to avoid overlooking PrEP candidates. In addition, primary care NPs should introduce easy-to-access, Internet-based resources to reinforce patient education. Last, PrEP promotional campaigns should be focused at the community level in gay, bisexual, transgender and queer populations.
