PrEP Optimization Intervention (PrEP-OI) is aims to educate healthcare providers on PrEP and assist providers in the appropriate targeting of patients at increased risk for HIV acquisition, initiating PrEP when appropriate, and providing guidance on the ongoing monitoring and adherence counseling of patients on PrEP. The intervention includes a web-based panel management tool (called PrEP-Rx) and PrEP coordination (by a PrEP Coordinator). The PrEP-OI study will take place among participating primary care clinics across the San Francisco Department of Public Health.
Despite data indicating nearly 80,000 individuals starting HIV pre-exposure prophylaxis (PrEP) by the end of 2015, the Centers for Disease Control and Prevention (CDC) estimates that there are over 1.2 million adults with a substantial risk for HIV acquisition. Therefore, only 6% of these individuals are receiving PrEP. One of the barriers to PrEP implementation is lack of healthcare provider (HCP) knowledge and willingness to prescribe it. In a 2015 national survey, only 66% of primary care clinicians were aware of PrEP. However, once PrEP was defined, 91% indicated a willingness to prescribe it for high risk patients and expressed an interest in education about how to deliver PrEP. A descriptive report on the early experiences with PrEP uptake and delivery in San Francisco identified the following priority steps for HCPs to address PrEP delivery issues and to maximize PrEP's public health impact: (1) increase PrEP knowledge among HCPs and (2) expand PrEP access by training HCPs and developing tools to facilitate PrEP delivery in clinical settings. Additionally, based on the framework of the PrEP care continuum, interventions to enhance PrEP uptake include HCP education, tools to assess sexual risk, and systems to minimize HCP burden. Given these proposals and recommendations, innovative and effective approaches are needed to support and provide guidance to HCPs regardless of level of experience prescribing PrEP.
The investigators propose a PrEP optimization intervention targeted at HCPs to increase PrEP uptake and persistence among those at risk for HIV acquisition. This intervention includes: (1) an integrated web-based panel management tool called PrEP-Rx, which provides structured HIV risk assessment, automates reminders for laboratory testing and appointments, and reports patients' history of PrEP use; and (2) a centralized PrEP coordination overseen by a clinical support staff (referred to as the PrEP coordinator) who can identify individuals at high risk for HIV through direct patient contact or by reviewing registries for sexually transmitted infections (STIs) and who can support multiple HCPs. PrEP-Rx consists of three components: (a) Risk Assessment, (b) Provider Dashboard, and (c) Knowledge Base. The brief online behavioral Risk Assessment will be provided to patients to complete prior to their initial visits with HCPs. This assessment allows patients to respond to sensitive risk questions in private, removes the need for HCPs to ask detailed risk questions, provides a standardized and comprehensive view of patient's HIV risk, and decreases the time burden on HCPs. Based on responses to the Risk Assessment, a patient's risk is categorized (high, medium, or low) and results are presented to the HCP on a "Provider Dashboard" along with laboratory test results that are required prior to PrEP initiation, and the patient's history of PrEP use (if applicable). Based on these data, the HCP and patient can discuss the risks and benefits of PrEP initiation. If a PrEP prescription is given, PrEP-Rx will generate automated follow-up reminders which are sent to the PrEP Coordinator for scheduling office appointments or laboratory visits. The activities of PrEP-Rx and the role of the HCP are augmented and managed by the PrEP Coordinator, who has the ability to identify and contact patients who have tested positive for STIs, follow-up with patients to minimize loss-to-follow-up and improve adherence, and ensure timely laboratory monitoring. PrEP-Rx also contains a Knowledge Base for HCP education and ongoing training.
Therefore, the investigators propose the following aims:
Primary Aim: Evaluate the efficacy of the PrEP optimization intervention (PrEP Coordinator + PrEP-Rx) to increase PrEP prescriptions through a stepped-wedge design among 10 San Francisco primary care clinics. The investigators hypothesize that the mean number of prescriptions issued will be significantly higher when the clinics use the PrEP intervention versus when they do not.
- Explore differences in PrEP initiation, duration of use, and reasons for discontinuation based on patient's age, race/ethnicity, and sex/gender, and by clinic and HCP characteristics among study clinics.
- Explore sustainability of the intervention during an eight-month follow-up after the Stepped-wedge Phase.
- Investigate facilitators and barriers of PrEP delivery and experiences with the proposed PrEP intervention through qualitative interviews with HCPs, PrEP Coordinators, and clinic directors of study clinics.
The combination of the PrEP Coordinator plus PrEP-Rx has the potential to improve all steps of the PrEP continuum and enhance overall care by identifying individuals at high risk of HIV acquisition, standardizing HIV risk assessment, helping in PrEP initiation, systematizing follow-up visits or laboratory assessments, and educating HCPs about emerging PrEP data. These goals can have a significant public health impact and be attained with minimal burden on existing clinic resources.
