Implementation Science of Integrating Pre-Exposure Prophylaxis in Pharmacist-Led Services in the United States

BACKGROUND

Racial inequities in HIV in the United States (US) are pervasive. Pre-exposure prophylaxis (PrEP) is one of the most effective yet underutilized HIV prevention strategies, and stark inequities in PrEP uptake exist. Lack of access to PrEP clinics is a major barrier to access that could be overcome by integrating pharmacists into the provision of PrEP services including prescribing and dispensing.

METHODS

A number of reviews have shown promise in folding pharmacies into the expansion of PrEP services, but this review extends those by examining the implementation science evidence of pharmacist-led PrEP services in the US. We reviewed literature over the past five years of the implementation science of pharmacist PrEP services (2018-2023) and present seminal findings in this area.

RESULTS

Only two studies are anchored within an implementation science framework despite all studies assessing common implementation science constructs. Overwhelming evidence supports feasibility and adoption of PrEP services in pharmacies yet gaps in workflow integration, scalability and sustainability exist.

CONCLUSION

Continuing to build the implementation science evidence of pharmacy-based PrEP services is critical to standardize our measures across varying contexts and inform policy efforts that support pharmacy-based PrEP services.

Pharmacist Prescribing Models for HIV Pre-exposure and Post-exposure Prophylaxis

State strategies for pharmacist prescribing exist on a continuum from most restrictive to least restrictive. Using human immunodeficiency virus (HIV) pre-exposure prophylaxis and post-exposure prophylaxis as a case study, there are 3 viable pharmacist prescribing models: (1) population-based collaborative practice agreements; (2) government protocols; and (3) standard of care prescribing. The advantages and disadvantages of these 3 models are reviewed.

The Role of Community Pharmacies in Providing Access to HIV Post-exposure Prophylaxis (PEP)

HIV affects an estimated 1.2 million individuals in the United States and is disproportionately concentrated among African Americans, Latinos, and people of multiple races. Post-exposure prophylaxis (PEP) substantially decreases HIV transmission when started within 72 h after exposure, but problems of accessibility have hindered its widespread usage in communities at risk for HIV infection. Pharmacy-initiated PEP access was first permitted in New York City in 2017, allowing pharmacists to provide a 7-day supply of PEP without a prescription for consumers at high risk for HIV infection. It was expected that the broad reach and accessibility of community pharmacies would increase timely access to PEP for all individuals, especially those who already face significant barriers to accessing the healthcare system. Since then, eleven other states have followed suit and expanded the scope of outpatient pharmacy practice in order to increase the availability of HIV PEP but prescribing laws in over 75% of the US have not been changed. Much of the existing literature on HIV prevention focuses on PrEP access barriers with limited information on PEP access in the US. In this paper, we review the current status of pharmacist-initiated PEP in the US as part of the End the HIV Epidemic (EHE) initiative.

Facilitators and barriers to community pharmacy PrEP delivery: a scoping review

INTRODUCTION

Pre-exposure prophylaxis (PrEP) is an effective medication to reduce the risk of acquiring HIV. PrEP is available free of charge in the UK from sexual health clinics. Expanding PrEP delivery to community pharmacies holds promise and aligns with UK government goals to eliminate new cases of HIV by 2030. The aim of this scoping review was to describe the existing evidence about the barriers to and facilitators of community pharmacy oral PrEP delivery, for pharmacists and pharmacy clients, as aligned with the Capacity Opportunity, Motivation Behaviour (COM-B) Model.

METHODS

Five bibliographic and five review databases were searched from inception to August 2023. Literature of any study design was included if it discussed barriers and facilitators of community pharmacy PrEP delivery. Trial registrations, protocols and news articles were excluded.

RESULTS

A total of 649 records were identified, 73 full texts were reviewed and 56 met the inclusion criteria, predominantly from high-income/westernized settings. Most of the included literature was original research (55%), from the United States (77%) conducted during or after the year 2020 (63%). Barriers to PrEP delivery for pharmacists included lack of knowledge, training and skills (capability), not having the necessary facilities (opportunity), concern about the costs of PrEP and believing that PrEP use could lead to risk behaviours and sexually transmitted infections (motivation). Facilitators included staff training (capability), time, the right facilities (opportunity), believing PrEP could be a source of profit and could reduce new HIV acquisitions (motivation). For clients, barriers included a lack of PrEP awareness (capability), pharmacy facilities (opportunity) and not considering pharmacists as healthcare providers (motivation). Facilitators included awareness of PrEP and pharmacist's training to deliver it (capability), the accessibility of pharmacies (opportunity) and having an interest in PrEP (motivation).

DISCUSSION

To effectively enhance oral PrEP delivery in UK community pharmacies, the identified barriers and facilitators should be explored for UK relevance, addressed and leveraged at the pharmacy team, client and care pathway level.

CONCLUSIONS

By comprehensively considering all aspects of the COM-B framework, community pharmacies could become crucial providers in expanding PrEP accessibility, contributing significantly to HIV prevention efforts.

Comparing open-ended question methods to vignette methods to explore willingness to obtain pre-exposure prophylaxis access in pharmacies among black men who have sex with men

Black men who have sex with men (BMSM) are at higher risk of HIV transmission than any other group; however, their uptake of the highly effective HIV prevention medication, pre-exposure prophylaxis (PrEP), is low. In collaboration with a communitybased organization in Atlanta, Georgia, we explored ten HIV-negative BMSM's willingness to obtain PrEP in pharmacies using standard open-ended and vignette qualitative methods. Three overarching themes were identified: privacy, patient-pharmacist interactions, and HIV/STI screening. While open-ended questions allowed participants to provide broad answers on their willingness to receive prevention services at a pharmacy, the vignette drew out specific responses to facilitate in-pharmacy PrEP delivery. Using both openended questions and vignette data collection strategies, BMSM reported high willingness to screen for and uptake PrEP in pharmacies. However, the vignette method allowed for greater depth. Open-ended questions elicited responses that highlighted general barriers and facilitators of PrEP dispensing in pharmacies. However, the vignette allowed participants to customize a plan of action that would best fit their needs. Vignette methods are underutilized in HIV research and may be helpful in supplementing standard open-ended interview questions to uncovering unknown challenges about health behaviors and obtain more robust data on highly sensitive research topics in HIV research.

Trends of nonoccupational postexposure prophylaxis in the United States

OBJECTIVE

To describe national annual rates of nonoccupational postexposure prophylaxis (nPEP) in the United States.

DESIGN

Retrospective cohort study of commercially insured individuals in the Merative MarketScan Database from January 1, 2010 to December 31, 2019.

METHODS

Patients at least 13 years old prescribed nPEP per recommended Centers for Disease Control and Prevention guidelines were identified using pharmacy claims. Rates of use were described overall and stratified by sex, age group, and region. These rates were qualitatively compared to the diagnosis rates of human immunodeficiency virus (HIV) observed in the data. Joinpoint analysis identified inflection points of nPEP use.

RESULTS

Eleven thousand, three hundred and ninety-seven nPEP users were identified, with a mean age of 33.7 years. Most were males (64.6%) and lived in the south (33.2%) and northeast (32.4%). The rate of nPEP use increased 515%, from 1.42 nPEP users per 100 000 enrollees in 2010 to 8.71 nPEP users per 10 000 enrollees in 2019. The comparative nPEP use rates among subgroups largely mirrored their HIV diagnosis rates, that is, subgroups with a higher HIV rate had higher nPEP use. In the Joinpoint analysis significant growth was observed from 2012 to 2015 [estimated annual percentage change (EAPC): 45.8%; 95% confidence interval (CI): 29.4 - 64.3] followed by a more moderate increase from 2015 to 2019 (EAPC 16.0%; 95% CI: 12.6-19.6).

CONCLUSIONS

nPEP use increased from 2010 to 2019, but not equally across all risk groups. Further policy interventions should be developed to reduce barriers and ensure adequate access to this important HIV prevention tool.

Opportunities to Increase Access to HIV Prevention: Evaluating the Implementation of Pharmacist-Initiated Pre-exposure Prophylaxis in California

Background

Pharmacies are a promising setting through which to expand access to human immunodeficiency virus (HIV) prevention, including pre-exposure and post-exposure prophylaxis (PrEP and PEP, respectively). We aimed to evaluate and inform the implementation of California's Senate Bill 159 (2019), allowing pharmacists to independently prescribe PrEP and PEP.

Methods

From October through December 2022, we conducted a cross-sectional study of 919 California pharmacists and pharmacy students, primarily recruited via the email listservs of professional organizations. Participants completed an online survey assessing the implementation of pharmacist-initiated PrEP/PEP, including knowledge, attitudes, practices, perceived barriers, and implementation preferences elicited through a discrete choice experiment.

Results

Among 919 participants (84% practicing pharmacists, 43% in community pharmacies), 11% and 13% reported that pharmacists at their pharmacy initiate PrEP and PEP, respectively. Most believed that pharmacist-initiated PrEP/PEP is important (96%) and were willing to provide PrEP (81%); fewer (27%) had PrEP/PEP training. Common implementation barriers were lack of staff/time and payment for pharmacist services. Participants preferred PrEP implementation models with in-pharmacy rapid oral HIV testing and pharmacists specifically hired to provide PrEP services.

Conclusions

Despite pharmacists' supportive attitudes, Senate Bill 159 implementation in California pharmacies remains limited, in part due to policy-level and organizational-level barriers. Ensuring PrEP/PEP-related payment for services and sufficient workforce capacity is key to leveraging pharmacists' role in HIV prevention.

Examination of HIV Preexposure Prophylaxis Need, Availability, and Potential Pharmacy Integration in the Southeastern US

Importance

Daily preexposure prophylaxis (PrEP) use can prevent up to 99% of HIV infections; however, PrEP uptake is low due to poor access to PrEP-prescribing locations for populations at increased risk for HIV, especially in the southeastern US. Pharmacies are a feasible option to increase PrEP access, but little is known about how they could complement current PrEP-prescribing locations.

Objective

To examine geographic distributions of current PrEP-prescribing locations compared with pharmacies and the facility to need ratios (PFNRs) according to HIV risk in the Southeast and describe the potential reach of pharmacies to expand PrEP access.

Design, Setting, and Participants

Data for this cross-sectional study of PrEP-prescribing locations and pharmacies were compiled from January 1 to December 31, 2021. States or specific counties in the Southeast included in this study were jurisdictions identified as high-priority areas for the Ending the HIV Epidemic in the US (EHE) initiative.

Exposure

Expansion of HIV prevention services to pharmacies.

Main Outcomes and Measures

Choropleth maps of 5-year HIV risk per 100 000 persons were developed for EHE jurisdictions in the southeastern US. PrEP-prescribing locations (obtained from a national database of PrEP prescribers) and pharmacies (obtained from state pharmacy boards) were overlayed on HIV risk maps. The PFNRs by state were calculated as number of facilities (PrEP-prescribing locations or pharmacies) divided by 5-year HIV risk per 100 000 persons. Lower PFNRs indicated lower geographic availability of locations to meet the needs of the population at risk for HIV. The PFNRs for current PrEP-prescribing locations vs pharmacies were compared.

Results

Among the 2 southeastern states and 13 counties in 4 southeastern states included, PrEP-prescribing locations were unequally distributed across EHE areas, with substantially fewer in areas at high risk for HIV. Pharmacies were evenly dispersed across areas regardless of HIV risk. The mean PFNR across all states for current PrEP-prescribing locations was 0.008 (median, 0.000 [IQR, 0.000-0.003]); for pharmacies, it was 0.7 (median, 0.3 [IQR, 0.01-0.1]). The PFNRs were at least 20.3 times higher for pharmacies compared with PrEP-prescribing locations. States with the greatest potential increase in PFNRs with expansion to pharmacies included Kentucky, South Carolina, and Tennessee.

Conclusions and Relevance

The findings of this cross-sectional study suggest that expanding HIV prevention services to pharmacies in EHE areas in the Southeast could significantly increase capacity to reach individuals at increased risk of HIV transmission. Legislation aimed at allowing pharmacists to prescribe PrEP and provide HIV prevention services may be an important next step in ending the HIV epidemic.

A Qualitative Systematic Literature Review of the Role of U.S. Pharmacists in Prescribing Pre-Exposure Prophylaxis (PrEP)

Pre-Exposure Prophylaxis (PrEP) is an effective treatment to combat the human immunodeficiency virus (HIV) endemic, but the uptake of PrEP has been low in the United States (U.S.). While individuals may access PrEP via obtaining a prescription from their prescriber and having it dispensed by their pharmacist, less cumbersome access points may exist. This systematic literature review evaluates qualitative literature to explore the role of pharmacists, pharmacy services, and interprofessional collaborations for persons seeking PrEP in the United States. Four electronic databases (PubMed, Scopus, CINAHL, and Embase) were searched in February 2022 and yielded 3841 results. After excluding duplicates, two researchers reviewed 2461 studies. These results were screened for inclusion and exclusion criteria and yielded 71 studies for full review. Out of these 71 studies, five studies met the pre-selected inclusion criteria. Of the five studies, four were qualitative studies, and one was a mixed-methods study. The studies examined different aspects of initiating PrEP and diverse outcomes, such as screening for PrEP, barriers to access PrEP, feasibility to access PrEP, accessibility via community pharmacy to PrEP, and interdisciplinary collaboration between members of the healthcare team to expand patient access to PrEP. A gap in the qualitative literature focusing on U.S. pharmacists' roles in initiation and provision of PrEP for diverse populations may exist. While PrEP promotion and uptake are largely affected by convenience and accessibility, future interventions and strategies should include training pertaining to PrEP screening, stigma reduction, privacy considerations, and PrEP dispensing.

Characterizing the Impact of the COVID-19 Pandemic on HIV PrEP care: A Review and Synthesis of the Literature

The global COVID-19 pandemic and associated lockdown measures have caused disruptions to sexual health services and created additional barriers to the continuity of HIV pre-exposure prophylaxis (PrEP) among key populations. This review provides an examination of the influences of the pandemic on engagement in the PrEP care continuum. Using the PRISMA guideline, 46 studies were included in this review and the synthesis. Most of the studies were conducted in high-income settings through quantitative analysis. A majority of studies examining the changes in PrEP use suggested a decline or discontinuation in PrEP uptake during the pandemic. The most common reasons for stopping using PrEP were perceived barriers to PrEP-related care, having reduced sexual behaviors and fewer sexual partners, and reduced perceived risk of HIV infection. Limited studies documenting an increase in PrEP uptake were all in specific PrEP optimizing programs. During the pandemic, there is also an emerging trend of switching to on-demand PrEP from daily oral PrEP. Future studies should understand the mechanism of strategies that facilitated the improvements during the pandemic. PrEP implementation programs should consider alternative PrEP modalities and provide consistent and comprehensive knowledge about correct information.

An observational study of the extent of naloxone furnishing in California Central Valley community pharmacies

BACKGROUND

California has sought to expand medication access and improve public health by authorizing pharmacists in California to prescribe certain medications since 2014. Medications with pharmacist-initiated prescribing, or furnishing, include naloxone, hormonal contraception, postexposure prophylaxis/preexposure prophylaxis, and nicotine replacement therapy. In light of the United States' opioid epidemic, naloxone, an opioid antagonist, this study considered furnishing rates in urban areas of California. Research from 2020 found 42.5% of pharmacies furnished naloxone. However, there has been limited study of furnishing outside of urban areas.

OBJECTIVE

This study assessed pharmacist furnishing rates of naloxone in California's Central Valley and identified barriers and facilitators to implementation.

METHODS

From April to May 2022, the researchers first conducted a cross-sectional, observational study of community and mail-order pharmacies in California's largely rural Central Valley, then collected interview data from a subset of pharmacists in stores that indicated they furnished naloxone.

RESULTS

Forty-three percent of Central Valley pharmacies reported that they furnished naloxone. Interview respondents reported that barriers to furnishing included time restrictions, cost to patients, stigma, and language barriers.

CONCLUSIONS

Furnishing rates in the Central Valley were slightly higher (43.4%) than those reported in previous research focusing on urban areas of California (42.5%). Identified barriers to furnishing were consistent with those identified in previous research. These findings suggest that further policy interventions may be needed to reduce out-of-pocket costs, establish stronger pharmacist-provider relationships, and provide education combatting stigma against opioid users to increase naloxone furnishing.
