PrEP uptake is dependent on healthcare provider awareness, knowledge of eligibility criteria, and ability to either prescribe or make an appropriate referral. The purpose of this investigation was to assess awareness, knowledge, and familiarity with PrEP guidelines and their relation to PrEP prescription and referral intentions among healthcare professional students representing three different disciplines. This is the first study to examine a large sample of clinicians in academic training programs who have the capacity to become part of the PrEP prescription or referral process. Findings indicate that PrEP awareness, knowledge, and familiarity with prescribing guidelines differs by discipline, with PharmD students reporting the highest levels of each. Medical students reported the highest comfort prescribing PrEP, greater familiarity with PrEP and increased willingness to prescribe. These results enhance our understanding of the relevant experiences and perspectives of future healthcare providers that influence their knowledge towards the promotion of PrEP.
PrEP Care Continuum
Utilizing PrEP as an HIV prevention tool is a more complex process than simply prescribing the drug, patient monitoring, and prescription renewal. The PrEP care continuum is a multi-step process that necessitates intervention focused on PrEP awareness, uptake, and adherence and retention (28). Pharmacists, nurse practitioners, and physicians play key roles in each of these steps. Understanding gaps in training can inform professional education to increase comfort and willingness to intervene across the PrEP care continuum as students transition into their careers.
Interdisciplinary Approaches to PrEP Care
In this sample, PharmD students had the greatest PrEP awareness, PrEP knowledge, and familiarity with prescribing guidelines. They also reported the lowest exposure to HIV-infected patient populations. Taken together, this suggests that PharmD programs may be providing more PrEP-related education than other practical healthcare disciplines. Community pharmacists are traditionally utilized in PrEP care through filling prescriptions and counselling patients taking PrEP as part of the adherence and retention step of the PrEP care continuum. While pharmacists do not have prescribing privileges in New York State, they are uniquely positioned to educate community members about HIV prevention options including PrEP, and have the ability to refer PrEP candidates to providers, thereby becoming involved in both the awareness and uptake steps in PrEP care. Compared to students in other disciplines, PharmD students were less willing to refer a potential PrEP candidate. As such, emphasis on reducing barriers to referrals during academic training may be an important intervention to encourage pharmacists to view themselves as significant contributors in PrEP care beyond maintenance stages. Furthermore, pharmacists may be more integral to adherence and retention than prescription refills alone due to factors such as advanced knowledge, geographic accessibility to vulnerable populations, and patient trust and rapport (29). Similar to their role in HIV treatment maintenance, pharmacists have unique access to data on timeliness of PrEP refill as well as periodic patient interactions (30, 31). As such, delayed refills could prompt pharmacists to discuss PrEP adherence with patients, building relationships to reinforce and optimize PrEP retention. More focus on PrEP counselling is needed during graduate training to increase confidence in patient education across the PrEP care continuum (32).
Nurse practitioner students reported lower PrEP awareness, PrEP knowledge, familiarity with prescribing guidelines, and relatedly, less comfort prescribing PrEP than students in other disciplines. This is a disappointing finding as the great majority of NP students in the sample had at least some experience with HIV-infected patient populations and many of them may continue to interface with vulnerable populations at increased risk for HIV acquisition. Previous work has shown prior exposure to HIV-infected populations to be a strong predictor of intentions to prescribe PrEP (12, 15). Additionally, nurse practitioners have a skillset that can be uniquely leveraged to decrease PrEP barriers and increase coverage in high-risk populations. As outlined by Nelson and colleagues (33), nurse-led approaches across the PrEP care continuum are a natural fit based on discipline-related assets including holistic approaches to patient care (e.g., patient education to increase awareness of HIV risk), advanced clinical skills to support PrEP uptake, and the ability to translate new evidence into practice to support adherence and retention. Because NPs are likely to encounter PrEP candidates, increasing their awareness and knowledge of PrEP and providing training on prescription guidelines is a vital step to increasing self-efficacy to prescribe, and subsequently increasing PrEP prescription coverage. As PharmD students reported increased PrEP knowledge, awareness, and familiarity with prescribing guidelines, there may be opportunities for transdisciplinary training, whereby NP students could attend existing workshops or seminars with PharmD students. This collaborative training may present a unique opportunity for introducing referral skills, and students could benefit from such an interdisciplinary approach. Furthermore, doctoral nursing education already includes competencies that align with the PrEP care continuum. Educational modules could include reframing such competencies within the context of PrEP.
Despite their lower PrEP awareness, PrEP knowledge, and familiarity with prescribing guidelines, MD students were most willing to refer and marginally more likely to prescribe PrEP. While uptake and adherence are natural intervention points for physicians within the context of PrEP care, their important position in awareness-raising and linkage to care should not be discounted. Perhaps lower knowledge and familiarity with prescribing contributes to the desire to refer patients to a more knowledgeable provider. In the current sample, program year was inversely related to willingness to prescribe, which may be attributable to deciding on a specialty in later program years (e.g., dermatology) that is less intuitively related to PrEP prescription. Increasing baseline knowledge to raise PrEP awareness and confidence to discuss sexual risk with patients regardless of specialty, paired with ability to refer to appropriate PrEP providers has the capacity to increase PrEP coverage at the population level. However, optimal uptake is still dependent on maximizing the number of potential prescribers. Increasing one’s ability to prescribe PrEP and retain patients in preventive care for medical students embarking on careers beyond infectious disease (e.g., primary care, family medicine, pediatrics) is an important target for intervention with physicians, especially since familiarity with PrEP prescribing guidelines is a significant predictor of willingness to prescribe. Additionally, graduate medical courses should work to debunk racial and other stereotypes about risk compensation, as such biases impede provider willingness to prescribe PrEP (23-25, 34). Future work could examine the extent to which hands-on experiences with high-risk populations (e.g., via clinical rotations) impact both willingness to prescribe and refer.
Implications
While New York has the fourth highest HIV incidence in the nation, the state has vowed to end the AIDS epidemic and is committed to increasing PrEP coverage as part of the strategy. Academic training programs in medicine, nursing, and pharmacy are key points of intervention to help achieve this goal. The 16 public and private medical schools in the State of New York train approximately 11% of the country’s medical students, nearly half of whom remain in the State to practice medicine. In 2017, New York State medical school enrolment was 10,743, an increase of more than 25% from 2002 (35). As key stakeholders in PrEP utilization in the future, medical students have an important role to play as future healthcare providers. In addition, New York houses 11 accredited DNP programs and 8 accredited PharmD programs, licensing over 2,500 nurse practitioners and 1,300 doctors of pharmacy over the last 5 years (36-39). Engaging with current students to better understand their PrEP knowledge in the future is critical in advancing the research field as prescribing patterns continue to grow in a variety of healthcare practice settings (40). Importantly, increasing knowledge and acceptance of PrEP via educational training of healthcare professionals has the potential to be both cost effective and to broadly influence the provision of PrEP to those at increased risk for HIV infection (41).
Findings of this work have implications for identifying potential intervention points in the training of students in healthcare professional programs to increase their capacity to prescribe directly or refer to other providers. These results echo recommendations in other work suggesting the need to expand healthcare professional students’ training on PrEP (26). As the PrEP continuum of care involves intervention points at patient awareness, uptake, and adherence and retention, interdisciplinary workforce training may be key to improving coverage. Case-based learning to facilitate active learning has been used in other medical school curricula when covering infectious disease content (42, 43) and may be a model for other health professional training programs to use when covering PrEP. This type of experiential learning may be ideal for students to work synergistically across disciplines and leverage knowledge already present in independent curricula. Importantly, the primary goal of this novel study is to identify gaps in knowledge to aid in development of educational programs to improve awareness, attitudes, comfort, and willingness to adopt PrEP among future healthcare professionals. While it is optimistic to expect growing PrEP uptake, more research is needed to understand future healthcare professionals’ knowledge of PrEP and the transition to actual prescription or referral behaviors.
Limitations
Given that this convenience sample was recruited from two universities in one state, these results are not generalizable to health professional students broadly speaking. Our results also may be affected by non-response bias as students who had no knowledge of PrEP may have chosen not to participate. Despite these limitations, this study provides one of the first examinations of PrEP knowledge and perceptions among future healthcare professionals.
