Preexposure Prophylaxis of HIV Infection: the Role of Clinical Practices in Ending the HIV Epidemic

Abstract

Purpose of review: The aim of this study is to summarise the recent evidence from high-income settings about providers' ability to deliver on the UNAIDS goal of at least three million people at substantial risk of HIV infection with PrEP by 2020, including awareness and knowledge about PrEP, willingness to prescribe PrEP, current levels of prescribing and service delivery models and issues.

Recent findings: Awareness about PrEP among health providers is growing, but at different pace depending on provider type. HIV and sexual health specialists are more likely to have knowledge about PrEP than generalists, and to be willing to prescribe it, mainly because of their closer contact with people at high risk for HIV and better risk assessment skills. There is still no consensus as to who should be responsible for providing PrEP, but clearly all hands on deck will be useful in delivering on the international target of three million people at substantial risk for HIV on PrEP by 2020. Only about 5% of the target has been reached so far. Local guidance and large-scale education and information programs for clinicians will be necessary to upskill health providers. High cost of PrEP is still a major barrier for its broad implementation, even in countries were PrEP roll-out has started. Health services are facing major structural challenges due to implementation of PrEP services to a substantial volume of patients. The early implementation experiences demonstrated that PrEP can be successfully delivered across a variety of settings, and a broad range of strategies and models of care can streamline PrEP delivery. Education of the providers and PrEP cost solutions will be essential for rapid roll-out of PrEP.
