Preference for and Efficacy of a PrEP Decision Aid for Women with Substance Use Disorders

PrEP Awareness, Interest, and Use among Women Who Inject Drugs in Seattle, Washington: A Mixed Methods Study

Women who inject drugs (WWID) are disproportionately affected by HIV and experience multiple barriers to PrEP use. We conducted a mixed methods study to assess PrEP awareness, interest, and use, and determinants of PrEP utilization among WWID at three community sites in Seattle, Washington from March-May 2023. Participants were ≥ 18 years old, spoke English, identified as women, had a history of injecting drugs, and self-reported a negative or unknown HIV status. We describe survey participant characteristics (n = 30) by PrEP candidacy based on behaviors associated with HIV acquisition. We concurrently recruited 16 WWID for semi-structured interviews, which were analyzed using the Rapid Assessment Process. Survey and interview data were triangulated to enhance interpretations. Among 30 WWID, 25 (83%) were PrEP candidates, of whom 19 (76%) had heard about PrEP; only 2 (8%) were currently using PrEP. Among PrEP candidates, 13 (57%) reported interest in daily oral PrEP and almost half (n = 12, 48%) reported interest in injectable PrEP. Qualitative data revealed cursory PrEP knowledge and a strong interest in daily oral and injectable PrEP among those who perceived they were at risk for HIV. Several barriers to PrEP use were noted including housing instability, adherence challenges, limited perceived risk, and competing priorities like safety and substance use. While most WWID were aware of PrEP, qualitative data suggested significant misconceptions about PrEP, and many described complex, intersecting barriers to use. Our findings highlight the need for increased low-barrier, population-specific interventions to improve uptake and sustained use of PrEP among WWID.

Pre-Exposure Prophylaxis Awareness and Demand Creation: Overlooked Populations and Opportunities to Move Forward

BACKGROUND

Pre-exposure prophylaxis (PrEP) for HIV prevention has been available since 2012, but uptake remains disappointing and inequitable. Furthermore, there is little evidence on the effectiveness of interventions to increase PrEP demand among priority populations in the United States. The objectives of this article were to describe how consumer perceptions of PrEP vary by distinct population groups and identify gaps in PrEP awareness, knowledge, and interest.

METHODS

We synthesized evidence-based interventions to improve demand for PrEP in populations heavily burdened by HIV. The focus centered on consumer factors, how people's awareness of PrEP, especially people who are likely to benefit, influences PrEP uptake.

RESULTS

Awareness and equity in PrEP use among vulnerable populations in the United States remain low because of both demand-side obstacles and accessibility challenges. Designing an effective package of interventions to increase demand for PrEP involves integrating strategies that address awareness, knowledge, interest/motivation, and access.

CONCLUSIONS

The underutilization of PrEP among the 1.2 million individuals who could benefit from it highlights the need for effective demand creation to reduce disparities. To effectively increase awareness of the benefits of PrEP requires consideration of the characteristics of the target population and the structural inequalities that contribute to PrEP-related disparities. Demand creation activities can increase awareness, correct misconceptions, provide knowledge, and help people decide whether PrEP is a good fit for them. The utilization of implementation science frameworks is essential to address demand generation and supply-side barriers to PrEP use.

Examining the Role of Posttraumatic Stress and Depressive Symptoms in HIV Pre-exposure Prophylaxis (PrEP) Motivation Among Women Survivors of Intimate Partner Violence

Post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) are associated with functional impairments, yet little is known about their influence on HIV pre-exposure prophylaxis (PrEP) motivation among women survivors of intimate partner violence (IPV). Understanding how PTSD and MDD symptoms influence PrEP motivation is particularly important given survivors of IPV have an increased risk for HIV acquisition. The present study assessed the association between PrEP motivation with latent profiles of PTSD and MDD symptoms among women survivors of IPV. Data were collected from a sample of 285 women from Baltimore, MD, and New Haven, CT. Latent profile analysis (LPA) was performed to identify distinct patterns of depressive and PTSD symptoms among women survivors of IPV. Binary logistic regression was performed to examine the association of profile membership on PrEP motivation. A six-profile solution was determined to best fit the data. Profiles were characterized by: Profile 1, very low depressive and very low PTSD symptoms (28.07%); Profile 2, average depressive symptoms and low (below the mean) PTSD symptoms (21.05%); Profile 3, high depressive symptoms and low (below the mean) PTSD symptoms (9.8%); Profile 4, moderate depressive symptoms and high PTSD symptoms (15.78%); Profile 5, high PTSD avoidance and average depressive symptoms (17.1%); Profile 6, high depressive and high PTSD symptoms (8%). We found that, the odds of being in Stage 3 of the PrEP Motivational Cascade (PrEParation; defined by having access to a medical provider to prescribe PrEP, be willing to take PrEP, and self-identifying as an appropriate candidate for PrEP) compared to Stage 1 of the PrEP Motivational Cascade (Precontemplation; defined by being eligible for PrEP, but not willing to take PrEP and/or not self-identifying as an appropriate candidate for PrEP) were lower for women assigned to the low depressive symptoms and low PTSD symptoms profile (Profile 1 of the LPA) compared to women in the high depressive symptoms and High PTSD symptoms profile (Profile 6 of the LPA, OR = 0.22, 95% CI = 0.06-0.76, p = 0.02). Women assigned to the low PTSD symptoms and average depressive symptoms profile (Profile 2 of the LPA) had lower odds of being in Stage 3 (PrEParation) compared to Stage 1 (Precontemplation) compared to women assigned to the high depressive symptoms and High PTSD symptoms profile (Profile 6 of the LPA, OR = 0.25, 95% CI = 0.07-0.92, p = 0.037). Women survivors of IPV with higher PTSD and MDD symptoms expressed greater motivation to engage in PrEP compared to women survivors with low PTSD and low MDD symptoms. Findings support the CDC's clinical PrEP recommendations to integrate depression screening into PrEP services, but there is a critical need to also include PTSD screening. Further, MDD and PTSD symptoms may present differential barriers to PrEP motivation among women survivors of IPV. Precision care could synchronize trauma-informed practices and mental health treatment to engage survivors in PrEP services.

Testing the feasibility, acceptability, and preliminary efficacy of integrating accommodation strategies into an HIV prevention intervention for people who inject drugs with cognitive dysfunction

BACKGROUND

Cognitive profiles of individuals with opioid use disorder (OUD) limit patients' ability to learn, retain, and recall HIV prevention information. It also limits adherence to medications, such as pre-exposure prophylaxis (PrEP). Cognitive dysfunction accommodation strategies have shown promise at reducing HIV-related risk behaviors among individuals with OUD and increasing adherence to PrEP. This study investigated the feasibility, acceptability, and preliminary efficacy of integrating accommodation strategies into a behavioral HIV prevention intervention.

METHODS

This 2-arm single blind study provided 50 people who inject drugs (PWID) with OUD linkage to PrEP services and randomized them to a 4-week HIV prevention intervention condition. The active control condition received the HIV prevention intervention as treatment per usual, while the experimental condition received the enhanced HIV prevention intervention with added accommodation strategies. Participants completed acceptability ratings of intervention content and accommodation strategies post-intervention; feasibility was measured via participant recruitment and retention. HIV risk reduction information, motivation, and behavior (IMB) assessments and HIV risk reduction skills assessments were completed pre/post-intervention. Participants also completed weekly PrEP adherence assessments.

RESULTS

The intervention content received a high acceptability rating (89 %). Intervention feasibility was deemed acceptable, with 80 % of participants completing all study protocols. The accommodation strategies integrated into the HIV prevention sessions were also endorsed by 92 % of participants. Participants in the experimental condition had significant increases in retention and recall of how to perform HIV risk reduction skills including how to properly clean a syringe (p = 0.048) and how to accurately apply a female condom (p = 0.025), compared to the control condition. Weekly PrEP adherence was reported by the three (7.5 %) participants who indicated taking PrEP throughout the study. All three participants reported missing doses throughout each of the 4 weeks.

CONCLUSIONS

Results from this study highlight the potential for integrating accommodation strategies into behavioral HIV prevention interventions to reduce the risk of HIV among PWID. Future research is needed to evaluate the use of such strategies by larger and diverse samples of PWID, as well as whether accommodation strategies enable the retention and recall of HIV prevention information and HIV prevention skills over longer periods of time.

Rationale and design of a randomized clinical trial of integrated eHealth for PrEP and medications for opioid use disorders for women in the criminal legal system. The Athena study

BACKGROUND

Women involved in the criminal legal system have elevated rates of opioid use disorder, which is treatable, and HIV, which is preventable with pre-exposure prophylaxis (PrEP). There are significant social and structural barriers to integrated delivery of PrEP and medications for opioid use disorder (MOUD), limiting women's ability to access these life-saving interventions. In a two parallel-arm randomized controlled trial, we are assessing an innovative eHealth delivery model that integrates PrEP with MOUD and is tailored to meet the specific needs of women involved in the criminal legal system.

METHODS

We will recruit and enroll 250 women involved in the criminal legal system with opioid use disorder across two diverse settings (New Haven, CT and Birmingham, AL). Participants will be randomized to (a) the "Athena strategy," which includes a PrEP decision aid and integrated PrEP/MOUD delivery via eHealth; or (b) enhanced standard of care (SOC) that includes a decision aid-only. During 6-month follow-up, we will assess PrEP initiation as the primary clinical outcome and implementation outcomes that include acceptability, adoption, feasibility, fidelity, implementation cost, and sustainability.

DISCUSSION

Results could help determine if reducing the social and structural barriers to PrEP and MOUD for women involved in the criminal legal system will facilitate engagement in treatment and prevention services, thus alleviating health disparities.

A PrEP decision aid for women survivors of intimate partner violence: Task-shifting implementation to domestic violence service settings

BACKGROUND

Women exposed to intimate partner violence (IPV) experience multiple social and structural barriers to accessing HIV pre-exposure prophylaxis (PrEP), despite being at increased risk for HIV. In addition, few existing HIV prevention interventions address IPV. A recently developed PrEP decision aid for women has the potential to reach IPV survivors at risk for HIV if it could be integrated into existing domestic violence agencies that prioritize trust and rapport with female IPV survivors. Leveraging non-traditional service delivery mechanisms in the community could expand reach to women who are IPV survivors for PrEP.

METHODS

We conducted qualitative interviews and online qualitative surveys with 33 IPV survivors and 9 domestic violence agency staff at two agencies in Connecticut. We applied the Consolidated Framework for Implementation Research (CFIR) to understand barriers and facilitators to delivering a novel PrEP decision aid to IPV survivors in the context of domestic violence service agencies.

RESULTS

Most IPV survivors and agency staff thought the PrEP decision aid intervention could be compatible with agencies' existing practices, especially if adapted to be trauma-responsive and delivered by trusted counselors and staff members. PrEP conversations could be packaged into already well-developed safety planning and wellness practices. Agency staff noted some concerns about prioritizing urgent safety needs over longer-term preventive health needs during crisis periods and expressed interest in receiving further training on PrEP to provide resources for their clients.

CONCLUSIONS

IPV survivors and agency staff identified key intervention characteristics of a PrEP decision aid and inner setting factors of the service agencies that are compatible. Any HIV prevention intervention in this setting would need to be adapted to be trauma-responsive and staff would need to be equipped with proper training to be successful.

Pre-exposure prophylaxis (PrEP) among people who use drugs: a qualitative scoping review of implementation determinants and change methods

Implementation of pre-exposure prophylaxis (PrEP) to prevent HIV transmission is suboptimal in the United States, particularly among people who use drugs (PWUD). PrEP research among PWUD is scarce, and the factors that impact implementation are largely unknown. Therefore, we conducted a scoping review of implementation determinants (i.e., barriers and facilitators), as well as the change methods (implementation strategies and adjunctive interventions) that have been evaluated to increase PrEP implementation and use among PWUD. We identified 32 peer-reviewed articles assessing determinants and five that evaluated change methods. Determinants were coded using the updated Consolidated Framework for Implementation Research (CFIR), which is an established framework to understand the multilevel barriers and facilitators associated with implementation. Findings indicate that most research was conducted among PrEP recipients (i.e., patients), focusing on awareness and willingness to use PrEP, with less focus on factors impacting clinicians and service delivery systems. Moreover, very few change methods have been evaluated to improve clinician adoption and adherence to CDC guidelines for PrEP provision and/or recipient uptake and adherence to PrEP. Future research is needed that focuses on factors impacting implementation from a clinician standpoint as well as innovative change methods to increase PrEP awareness, reach, adoption, and sustained adherence to guidelines. Implementation Science offers a wealth of knowledge to speed up the effort to end the HIV epidemic in the United States.

PrEP for people who use opioids: A NIDA clinical trials network survey study in Southern U.S. cities where HIV incidence is high

BACKGROUND

People who use opioids (PWUO) are at increased risk for HIV. Pre-exposure prophylaxis (PrEP) is effective but underutilized as HIV prevention among PWUO. This study examined predictors of willingness to take daily oral PrEP and long-acting injectable (LAI) PrEP among PWUO across eight Southern urban cities with high HIV incidence.

METHODS

HIV-negative PWUO (N = 308) seeking services in community-based programs participated in this cross-sectional survey study. Measures included demographics, sexual risk behavior, substance use frequency, and awareness of and willingness to take oral and injectable PrEP. Data were analyzed using mixed-effects models.

RESULTS

Willingness to take daily oral and LAI PrEP was moderately high (69.16% and 62.02%, respectively). Half had heard of PrEP, but only 4% had ever taken it. Only education and condomless vaginal sex predicted willingness to take oral PrEP. Only education predicted willingness to take LAI PrEP. Polysubstance use was prevalent, with substantial proportions of PWUO reporting frequent use of injection drugs (opioids or stimulants, 79.5%), non-injection opioids (73.3%), non-injection stimulants (71.1%), cannabis (62.6%), and hazardous drinking (29.6%). About 20% reported past-year condomless anal sex, and one-third reported past-year condomless vaginal sex.

CONCLUSIONS

PWUO in this study were amenable to PrEP, particularly in light of education and condomless vaginal sex. Careful consideration for matching PrEP messaging to the PWUO audience is needed. PrEP promotion should expand beyond men who have sex with men to include groups such as these predominantly heterosexual, polysubstance-using PWUO with HIV risk who were open to both formulations of PrEP.

Facilitators and Barriers to PrEP Acceptability and Initiation Among Opioid Treatment Program Patients and Staff

The Centers for Disease Control and Prevention recommends PrEP (pre-exposure prophylaxis) for people who use drugs, yet uptake remains low. This study explores the acceptability and potential uptake of PrEP among participants in an opioid treatment program (OTP). We conducted 26 in-depth, semistructured interviews with staff and patients at an OTP in Baltimore, Maryland. Overall, participants felt that providing PrEP within the program would be beneficial, but they noted competing priorities among populations engaging in high-risk behaviors and lack of willingness among groups with lower risk behaviors. Participants reported several barriers to PrEP use among people who use drugs and who use medications for opioid use, including cost, competing priorities, stigma, and misconceptions about who should use PrEP. Facilitators to PrEP use were described as health benefits, trusted relationships with providers, and existing resources in the opioid treatment program. Practitioners should consider addressing barriers to access and stigma within an OTP setting for HIV prevention tools.

HIV risk perception, pre-exposure prophylaxis (PrEP) awareness, and PrEP initiation intention among women who use drugs

INTRODUCTION

Women who use drugs (WWUD) are prime candidates for pre-exposure prophylaxis (PrEP) due to their elevated risk of acquiring HIV through biological, behavioral, and contextual factors. However, PrEP uptake among WWUD remains low. The relationship between unhealthy drug use and correlates of PrEP uptake in this vulnerable population is not well defined. The purpose of this study is to characterize the relationships between specific types and routes of drug use and several precursors of PrEP uptake among WWUD.

METHODS

The study collected data via a computer-based survey from 233 women living in New York City and Philadelphia who participated in a study designed to develop and pilot a women-focused intervention for PrEP uptake. The sample of cisgender, HIV-negative women were not currently taking PrEP but considered PrEP eligible. This analysis is focused on women's HIV risk perception, PrEP awareness, PrEP initiation intention, and any use of the following drugs: barbiturates, benzodiazepines, crack cocaine, powder cocaine, hallucinogens, heroin, methamphetamines, and prescription opioids.

RESULTS

Within the three months prior to study enrollment, 63.1 % of participants reported any drug use; 42 % reported polydrug use; 19.8 % had injected drugs; 75 % reported getting high or drunk before sex; and 44 % had been enrolled in drug treatment. Of our total sample, 41.2 % perceived themselves at risk for HIV infection, 41.6 % were aware of PrEP prior to the study, and 62.7 % intended to initiate PrEP after they were informed. When compared to other PrEP-eligible women, women who reported prescription opioid use and polydrug use perceived themselves at higher risk for HIV infection and had higher intention to start PrEP. However, they and women who reported injecting drugs also reported lower awareness of PrEP.

CONCLUSION

These findings have implications for increasing education about PrEP and the various modes of HIV exposure to support PrEP uptake in this vulnerable population.

Pre-exposure prophylaxis service among men who have sex with men in Malaysia: findings from a discrete choice experiment

Men who have sex with men (MSM) in Malaysia are disproportionately affected by HIV. As pre-exposure prophylaxis (PrEP) is being introduced, we assessed population-based PrEP delivery preferences among MSM in Malaysia. We conducted a discrete choice experiment through an online survey among 718 MSM. The survey included 14 choice tasks presenting experimentally varied combinations of five attributes related to PrEP delivery (i.e., cost, dosing strategy, clinician interaction strategy, dispensing venue, and burden of visits to start PrEP). We used latent class analysis and Hierarchical Bayesian modeling to generate the relative importance of each attribute and preference across six possible PrEP delivery programs. PrEP dosing, followed by cost, was the most important attribute. The participants were clustered into five preference groups. Two groups (n = 290) most commonly preferred on-demand, while the other three preferred injectable PrEP. One group (n = 188) almost exclusively considered cost in their decision-making, and the smallest group (n = 86) was substantially less interested in PrEP for reasons unrelated to access. In simulated scenarios, PrEP initiation rates varied by the type of program available to 55·0% of MSM. Successful PrEP uptake among Malaysian MSM requires expanding beyond daily oral PrEP to on-demand and long-acting injectable PrEP, especially at affordable cost.

Barriers and Facilitators to Pre-Exposure Prophylaxis by Men Who Have Sex with Men and Community Stakeholders in Malaysia

BACKGROUND

Men who have sex with men (MSM) in Malaysia are disproportionately affected by HIV. Pre-exposure prophylaxis (PrEP) is an evidence-based HIV prevention strategy; yet, uptake remains low among Malaysian MSM, who have a limited understanding of barriers to PrEP.

METHODS

We employed the nominal group technique (NGT), a structured mixed-methods strategy to understand the barriers and facilitators to PrEP use among Malaysian MSM, combined with a qualitative focus group. Six virtual focus group sessions, three among MSM (n = 20) and three among stakeholders (n = 16), were conducted using a video-conferencing platform. Rank-ordering of barriers from NGT was recorded, and thematic analysis was conducted for content.

RESULTS

Similar barriers were reported by MSM and community stakeholders, with aggregated costs associated with PrEP care (e.g., consultation with a clinician, medication, laboratory testing) being the greatest barrier, followed by limited knowledge and awareness of PrEP. Additionally, the lack of access to PrEP providers, the complex clinical protocol for PrEP initiation and follow-up, and social stigma undermined PrEP delivery. Qualitative discussions identified potential new strategies to overcome these barriers, including expanded outreach efforts to reach hard-to-reach MSM, a 'one-stop' delivery model for PrEP services, a patient-centered decision aid to guide PrEP uptake, and easy access to LGBT-friendly PrEP providers.

CONCLUSION

Current barriers may be overcome through governmental subsidy for PrEP and evidence-informed shared decision aids to support both MSM and PrEP providers.

Overlapping needs for sexual and reproductive health and HIV prevention in women with substance use disorders

OBJECTIVES

Women with substance use disorders have high unmet needs for HIV prevention and drug treatment and face challenges accessing care for other unique health issues, including their sexual and reproductive health.

METHODS

We did a cross-sectional evaluation of sexual and reproductive health behaviors and outcomes among women with substance use disorders, who were enrolled in one of two concurrent clinical trials of pre-exposure prophylaxis for HIV prevention. Descriptive analyses and bivariate logistic regression were used to assess factors driving contraceptive use, and other essential sexual and reproductive health services utilization and outcomes.

RESULTS

Among 226 women, 173 (76.5%) were of reproductive age. Most women had histories of unintended pregnancy (79.2%) or miscarriage (45.1%) and high HIV risk behaviors (53.5%). Most (61%) participants did not use any form of contraception at the time of assessment, although few (15%) reported pregnancy intentions. In bivariate models, ongoing criminal justice involvement was associated with 2.22 higher odds of not using contraception (95% confidence interval = 1.09-4.53; p = 0.03) and hazardous drinking was protective against not using contraception (odds ratio = 0.33, 95% confidence interval = 0.13-0.81; p = 0.02). Contraception use was not significantly associated with any other individual characteristics or need factors.

CONCLUSIONS

This is the first study that identifies the unmet sexual and reproductive health needs of women with substance use disorders who are engaging with pre-exposure prophylaxis. We found that women accessed some health services but not in a way that holistically addresses the full scope of their needs. Integrated sexual and reproductive care should align women's expressed sexual and reproductive health intentions with their behaviors and outcomes, by addressing social determinants of health.
