Increasing PrEP Use in Primary Care and Women’s Health Clinics
As of June 2017, physicians (staff, interns, residents, and fellows) accounted for more than three-quarters of VA PrEP index prescriptions. Among staff physicians, infectious diseases specialists initiated 67% of all prescriptions. Clinical pharmacists prescribed only 6%; APRNs and PAs prescribed 16% of initiations. This is unsurprising, as the field survey identified lack of awareness and specific training on PrEP care among providers without infectious diseases training as a common barrier.
The VA is the largest US employer of nurses, including more than 5,500 APRNs. In December 2016, the VA granted full practice authority to APRNs across the health care system, regardless of state restrictions in most cases.9In some states, this change in scope of practice (SOP) may allow for APRNs to become more involved in the prescribing of PrEP.
In 2015, the VA employed about 7,700 clinical pharmacists, 3,200 of whom had an active SOP that allowed for prescribing authority. In fiscal year 2015, clinical pharmacists were responsible for at least 20% of all hepatitis C virus (HCV) prescriptions and 69% of prescriptions for anticoagulants across the system.10 Clinical pharmacists are increasingly recognized for their extensive contributions to increasing access to treatment in the VA across a broad spectrum of clinical issues. With this infrastructure and expertise, clinical pharmacists also are well positioned to expand their scope to include PrEP.
To that end, the National PrEP Working Group worked closely with clinical pharmacists in the field and from the VA Academic Detailing Service (ADS) within the VA Pharmacy Benefits Management Services office. The ADS supports the development of scholarly, balanced, evidence-based educational tools and information for frontline VA providers using one-on-one social marketing techniques to impact specific clinical targets. These interventions are delivered by clinical pharmacists to empower VA clinicians and promote evidence-based clinical care to help reduce variability in practice across the system.11 An ADS module for PrEP has been developed and will be available in 2018 across the VHA to facilities participating in the ADS.
A virtual accredited training program on prescribing PrEP and monitoring patients on PrEP designed for clinical pharmacists will be delivered early in 2018 to complement these materials and will be open to all prescribers interested in learning more about PrEP. By offering a complement of training and clinical support tools, most of which are detailed in other sections of this article, the National PrEP Working Group is creating educational opportunities that are accessible in a variety of different formats to decrease knowledge barriers over PrEP prescribing and build over time a broader pool of VA clinicians trained in PrEP care.
Ensuring High-Quality PrEP Care
One system-level concern about expanding PrEP to providers without infectious diseases training is the quality of follow-up care. In order to aid noninfectious diseases clinicians, and nonphysician providers who are not as familiar with PrEP, several clinical support tools have been created, including (1) VA’s Clinical Considerations for PrEP to Prevent HIV Infection, which is aligned with CDC clinical guidance12; (2) a PrEP clinical criterion check list; (3) clinical support tools, such as prepopulated electronic health record (EHR) templates and order menus to facilitate PrEP prescribing and monitoring in busy primary care clinical settings; and (4) PrEP-specific texts in the Annie App, an automated text-messaging application developed by the VA Office of Connected Care, which supports medication adherence, appointment attendance, vitals tracking, and education.13
Available evidence indicates that there is potential for disparities in PrEP effectiveness in the VA related to varying medication adherence. Analysis of pharmacy refill records found that adherence with TDF/FTC was high in the first year after PrEP initiation (median proportion of days covered in the first year was 74%), but adherence was lower among veterans in VA care who were African American, women, and/or under age 45 years.8 This highlights the importance of enhanced services, such as Annie, to support PrEP adherence in at-risk groups as well as monitoring of HIV risk factors to ensure PrEP is still indicated.
Targeting PrEP Uptake for High-Risk Veterans
Although the VA’s overarching goal is to increase access to and uptake of PrEP across the VHA, it also is important to direct resources to those at greatest risk of acquiring HIV infection. The National PrEP Working Group has focused on the following critical implementation issues in the VA’s strategic approach to HIV prevention, with a specific focus on the geographic disparities between PrEP uptake and HIV risk across the VHA as well as disparities based on rurality, race/ethnicity, and gender.
