The efficacy of HIV pre-exposure prophylaxis (PrEP) has been demonstrated in four clinical trials to date; however, the success of PrEP is largely dependent on high levels of medication adherence. Due to their extensive experience and expertise in medication adherence counseling, as well as their ability to monitor and manage medication adverse effects and drug-drug interactions, clinical pharmacists are well-equipped to play a key role in effective PrEP utilization. Here we discuss reasons favoring the establishment of a protocol-based, pharmacist-run PrEP clinic.

The authors aimed to describe cell phone and Internet use and assess the correlation of Internet use for health care engagement purposes and HIV clinical outcomes among HIV-positive individuals. The authors conducted a national survey using online social media to examine cell phone and Internet use, self-reported HIV viral load (detectable vs. undetectable), and antiretroviral adherence rating (excellent vs. less than excellent). Participants (N = 1,494) were asked about their Internet use for health care engagement purposes (including e-mailing health care providers, refilling medications online, and making medical appointments online). Approximately 95% of participants accessed the Internet nearly daily or daily in the past month (mean hours on Internet use per day = 5.2) and 55.5% used the Internet for health care engagement purposes. Those who used the Internet for any health care engagement purposes had a 1.52-fold odds of reporting an undetectable viral load (p = .009) and a 1.49-fold odds of reporting excellent adherence (p = .001). Although Internet access and use were similar across racial/ethnic, educational, and socioeconomic groups, disparities existed with the use of the Internet for health care engagement purposes among racial/ethnic minorities, those with low to moderate financial stability, lower education, and history of incarceration. The authors' data reveal that among HIV-positive users of online social media, use of the Internet for health care engagement purposes is associated with better self-reported virologic and adherence outcomes.

Based on the results of the IPERGAY study, on-demand HIV pre-exposure prophylaxis (PrEP; also known as "non-daily PrEP," "event-driven PrEP," or "2-1-1 PrEP") is being requested more frequently by patients who have intermittent sexual risk or are unable/unwilling to take daily PrEP; therefore, clinicians will be increasingly required to familiarize themselves with its appropriate use. In this perspective, we summarize data related to on-demand PrEP, describe advantages and disadvantages for this alternative dosing strategy, and provide clinical counseling points.

Suboptimal engagement in HIV care increases the risk of HIV-related morbidity and mortality; however, a comprehensive and practical measure of engagement in care does not exist. The objective of our study was to identify and develop a composite of engagement in HIV care. From May to August 2013, we conducted a cross-sectional study of HIV-positive individuals who consented to participate in an online survey. Engagement in care was assessed by the following self-reported variables: (1) having attended an HIV health-care provider appointment in the past six months, (2) reporting a scheduled future HIV health-care provider appointment, (3) knowing their last CD4(+) cell count, (4) knowing their antiretroviral (ARV) medication names, (5) reporting ARV adherence ≥80% on the visual analog scale (VAS) and rating scale, (6) reporting adherence ≥90% on the VAS and rating scale, and (7) not having missed all ARVs for at least four days in a row in the past three months. To create the composite of engagement in care, the presence or absence of these variables were summed and categorized (7 = "high engagement," 5-6 = "moderate engagement," and 0-4 = "low engagement"). We examined the correlation between this composite and self-reported HIV viral load (VL; detectable versus undetectable) in a logistic regression model. We surveyed 1259 HIV-positive individuals: 85% reporting an undetectable VL and 67% reporting excellent adherence. Approximately 89%, 88%, and 67% of those with high, moderate, and low engagement, respectively, had an undetectable VL. Having moderate engagement was associated with 3.5-fold higher odds, and high engagement was associated with 4.0-fold higher odds of virologic undetectability compared to low engagement (overall p-value < 0.0001). Our data indicate that this novel and comprehensive composite of engagement may be a useful tool in clinical and research settings given its high correlation with virologic outcomes. Future research should validate this composite in other populations and examine it prospectively.

An alternative strategy for men who have sex with men (MSM) experiencing challenges with daily HIV pre-exposure prophylaxis (PrEP) includes 2-1-1 dosing. Understanding 2-1-1 PrEP facilitators and barriers, especially during the SARS-CoV-2 pandemic, may guide researchers and healthcare providers in future studies and clinical preparedness. We conducted a national cross-sectional study of MSM in the US who had taken 2-1-1 PrEP to examine facilitators and barriers of this on-demand PrEP dosing option. With the shelter-in-place orders in March 2020, this study was adapted to include questions on how the SARS-CoV-2 pandemic affected participants' PrEP use. A total of 140 individuals participated in the survey, 106 of which completed questions pertaining to the SARS-CoV-2 pandemic. The most common reasons for switching from once-daily to 2-1-1 PrEP included having sex less frequently (63.6%) and wanting to take fewer pills (46.4%). Participants reported high medication adherence based on each component of 2-1-1 PrEP dosing (>84%). The most common barriers with 2-1-1 PrEP dosing included unplanned sexual encounters resulting in missing the double-dose pre-sex (43.6%) and trouble remembering doses post-sex (29.3%). Facilitators of the 2-1-1 PrEP dosing strategy included reductions in sexual encounters (63.6%), preference to take fewer pills (46.4%), need to reduce cost (22.1%), and desire to reduce side effects (19.3%). Challenges to receiving PrEP services during the pandemic included obtaining laboratory testing (25.5%) and PrEP refills (either receipt of a refill authorization from a healthcare provider or processing of a refill from the pharmacy) (18.9%). 2-1-1 PrEP is an effective HIV prevention method; therefore, understanding facilitators and barriers of this dosing strategy can result in continuous provision of HIV prevention efforts, particularly during a pandemic.

Purpose

Given the consistent associations between younger age and numerous suboptimal clinical outcomes, there is a critical need for more research in youth living with human immunodeficiency virus (YLWH) and tailoring of health care delivery to the unique and complex needs of this population. The objective of this study was to examine the facilitators of and barriers to engagement in care among YLHW at the system and provider/staff level, as well as the barriers to using technology-based forms of communication with YLWH to improve retention and engagement in care.

Patients and methods

We conducted in-depth qualitative interviews with health care providers and staff members at the clinics and organizations serving YLWH in the San Francisco Bay Area.

Results

We interviewed 17 health care providers and staff members with a mean of 8 years of experience in providing clinical care to YLWH. Interviewees noted various facilitators of and barriers to engagement in care among YLWH, including the environment of the clinic (e.g., clinic location and service setting), provision of youth-friendly services (e.g., flexible hours and use of technology), and youth-friendly providers/staff (e.g., nonjudgmental approach). With regard to barriers to using technology in organizations and clinics, interviewees discussed the challenges at the system level (e.g., availability of technology, clinic capacity, and Health Insurance Portability and Accountability Act compliance), provider/staff level (e.g., time constraints and familiarity with technology), and youth level (e.g., changing of cellular telephones and relationship with provider/staff).

Conclusion

Given the need for improved clinical outcomes among YLWH, our results can provide guidance for clinics and institutions providing care for this population to enhance the youth-friendliness of their services and examine their guidelines around the use of technology.

HIV + White, Latino, and African Americans (N = 1131) completed a survey advertised on social media to re-examine the effect of depressive symptoms (via the Patient Health Questionnaire; PHQ-9) and race/ethnicity on antiretroviral therapy nonadherence (defined as past 3-month, 4-day treatment interruption). An adjusted logistic regression showed a 15 % increase in odds for a treatment interruption per 1-unit increase on the PHQ-9. The effect of depressive symptoms on nonadherence was greater for Latinos (OR = 1.80, p < 0.05), but not for African Americans, compared to Whites. The benefits of modern ART (e.g., simpler, forgiving to minor lapses) may not circumvent the effect of depressive symptomatology.

Background

Pre-exposure prophylaxis (PrEP) has been shown to be highly effective for the prevention of HIV in clinical trials and demonstration projects, but PrEP uptake and adherence outside of these settings in the United States has been limited. Lack of knowledge and willingness of health care providers (HCPs) to prescribe PrEP is an important barrier to implementation.

Objective

The objective of this study was to describe and examine the feasibility and acceptability of a PrEP Optimization Intervention (PrEP-OI) targeted at HCPs. The ultimate purpose of this intervention was to increase PrEP uptake, adherence, and persistence among those at risk for HIV acquisition.

Methods

This intervention included the following: (1) a Web-based panel management tool called PrEP-Rx, which provides comprehensive HIV risk assessment, automates reminders for follow-up, and reports patients' history of PrEP use; and (2) centralized PrEP coordination by a clinical support staff member (ie, the PrEP coordinator) who can identify individuals at risk for HIV, provide medical insurance navigation, and support multiple HCPs. Feasibility was evaluated based on HCPs' ability to log in to PrEP-Rx and use it as needed. Acceptability was assessed via individual formative qualitative interviews with HCPs after 1 month of the intervention.

Results

The intervention was feasible and acceptable among HCPs (N=6). HCPs identified system-level barriers to PrEP provision, many of which can be addressed by this intervention. HCPs noted that the intervention improved their PrEP knowledge; increased ease of PrEP prescription; and was likely to improve patient engagement and retention in care, enhance communication with patients, and improve patient monitoring and follow-up.

Conclusions

Given the critical role HCPs serve in disseminating PrEP, we created an easy-to-use PrEP optimization intervention deemed feasible and acceptable to providers. Further research on this tool and its ability to impact the PrEP continuum of care is needed.

Relying on the most frequently reported barriers to adherence and convenient definitions of non-adherence may lead to less valid results. We used a dominance analysis (a regression-based approach) to identify the most important barriers to adherence based on effect size using data collected through an online survey. The survey included the Adherence Barrier Questionnaire, self-reported non-adherence defined as a 4-day treatment interruption, and HIV clinical outcomes. The sample (N = 1217) was largely male, gay identified, and White. Nearly 1 in 3 participants reported "simply forgot" as a barrier; however, in a dominance analysis, it yielded a small effect size it its association with a 4-day treatment interruption. Further, dominance analyses stratified by race/ethnicity and age suggested that not all barriers impact all groups equally. The most frequently reported barriers to adherence were not the most important, and interventions should focus on barriers more strongly linked to clinical outcomes.
