The Pharmacist's Expanding Role in HIV Pre-Exposure Prophylaxis.

The efficacy of pre-exposure prophylaxis (PrEP) to prevent HIV has been firmly established; however, the success of PrEP largely depends on access to care as well as high levels of medication adherence. One of the key areas of focus for the National HIV/AIDS Strategy for 2020 in the United States calls for full access to comprehensive PrEP services where appropriate and desired, with support for medication adherence. Despite advances and advocacy for PrEP since approval for adults in 2012, large rates of prescribing disparity exist among gender and race/ethnicity. In 2016, only 3.7% of all PrEP users were women and only 11.2% were black. As one of the most widely accessible health care resources, pharmacists are well positioned to improve patient understanding, promote medication adherence, provide key risk reduction counseling, and enhance PrEP efficacy. Pharmacists' knowledge and accessibility in nearly every urban and rural community can be leveraged as part of a comprehensive HIV prevention strategy to expand access to care and improve population health. As trusted health care professionals, pharmacists develop a strong rapport with patients and may be the key to address current disparities in PrEP prescribing patterns as well as serve as an essential liaison between patients and other members of the multi-disciplinary care team. The purpose of this review is to summarize available data on pharmacist involvement in various models of care providing PrEP services and to identify opportunities to maximize and expand the role of the pharmacist to improve access to PrEP.
