Evidence and implication of interventions across various socioecological levels to address pre-exposure prophylaxis uptake and adherence among men who have sex with men in the United States: a systematic review

Estimating the potential value of MSM-focused evidence-based implementation interventions in three Ending the HIV Epidemic jurisdictions in the United States: a model-based analysis

INTRODUCTION

Improving the delivery of existing evidence-based interventions to prevent and diagnose HIV is key to Ending the HIV Epidemic in the United States. Structural barriers in the access and delivery of related health services require municipal or state-level policy changes; however, suboptimal implementation can be addressed directly through interventions designed to improve the reach, effectiveness, adoption or maintenance of available interventions. Our objective was to estimate the cost-effectiveness and potential epidemiological impact of six real-world implementation interventions designed to address these barriers and increase the scale of delivery of interventions for HIV testing and pre-exposure prophylaxis (PrEP) in three US metropolitan areas.

METHODS

We used a dynamic HIV transmission model calibrated to replicate HIV microepidemics in Atlanta, Los Angeles (LA) and Miami. We identified six implementation interventions designed to improve HIV testing uptake ("Academic detailing for HIV testing," "CyBER/testing," "All About Me") and PrEP uptake/persistence ("Project SLIP," "PrEPmate," "PrEP patient navigation"). Our comparator scenario reflected a scale-up of interventions with no additional efforts to mitigate implementation and structural barriers. We accounted for potential heterogeneity in population-level effectiveness across jurisdictions. We sustained implementation interventions over a 10-year period and evaluated HIV acquisitions averted, costs, quality-adjusted life years and incremental cost-effectiveness ratios over a 20-year time horizon (2023-2042).

RESULTS

Across jurisdictions, implementation interventions to improve the scale of HIV testing were most cost-effective in Atlanta and LA (CyBER/testing cost-saving and All About Me cost-effective), while interventions for PrEP were most cost-effective in Miami (two of three were cost-saving). We estimated that the most impactful HIV testing intervention, CyBER/testing, was projected to avert 111 (95% credible interval: 110-111), 230 (228-233) and 101 (101-103) acquisitions over 20 years in Atlanta, LA and Miami, respectively. The most impactful implementation intervention to improve PrEP engagement, PrEPmate, averted an estimated 936 (929-943), 860 (853-867) and 2152 (2127-2178) acquisitions over 20 years, in Atlanta, LA and Miami, respectively.

CONCLUSIONS

Our results highlight the potential impact of interventions to enhance the implementation of existing evidence-based interventions for the prevention and diagnosis of HIV.

Factors associated with discussing HIV pre-exposure prophylaxis (PrEP) among Jamaican medical providers

BACKGROUND

The Ministry of Health and Wellness of Jamaica has endorsed the use of pre-exposure prophylaxis (PrEP) as an HIV prevention strategy; however, PrEP was not included in the national HIV prevention program in 2021.

METHODS

A cross-sectional online study involving physicians in Jamaica was conducted in 2021 to describe PrEP awareness, beliefs, attitudes, and practices. The study also assessed individual and social factors associated with discussing PrEP with patients and willingness to prescribe PrEP.

FINDINGS

The mean age and standard deviation (SD) of the 69 physicians who completed the survey were 45.5 ± 13.6 years. Most of the participants (80%) reported that they were somewhat familiar with PrEP. PrEP attitude and perceived comfort in prescribing PrEP were moderate among participating physicians, with a mean and SD of 3.9 ± 0.8 and 3.6 ± 0.9 respectively. Six percent of physicians reported that they had prescribed PrEP and 17% had discussed PrEP with their patients in the past year. However, most (90%) reported that they were willing to prescribe PrEP after being informed about it. In the unadjusted model, identifying as Christian (compared to non-Christian) and reporting stronger homophobic beliefs were associated with reduced odds of discussing PrEP with patients. In the multivariable model, only homophobia remained statistically significant (OR, 0.24; 95% CI: 0.07-0.63).

CONCLUSION

The findings suggest that physicians in Jamacia may be willing to prescribe PrEP; however, homophobia is a barrier to discussions, underscoring the need for the Ministry of Health and Wellness to recognize the role that homophobia plays in the national HIV program to further reduce HIV incidence in Jamaica.

Factors associated with PrEP use in a community sample of African American men who have sex with men (MSM) and transgender women (TGW) in the United States Midwest

Black sexual minority men who have sex with men (MSM) in the United States are at disparate risk for contracting HIV infection, but pre-exposure prophylaxis (PrEP) use is suboptimal. Social network methods were used to recruit a community sample of racial minority MSM and transgender women (TGW) in two Midwestern US cities. 250 PrEP-eligible (HIV-negative) participants completed measures assessing current and intended PrEP use; demographic characteristics; PrEP knowledge, attitudes, norms, stigma, and self-efficacy; and structural barriers to PrEP. Multivariate analyses established predictors of current and intended PrEP use. Only 12% of participants reported currently using PrEP, which was associated with greater PrEP knowledge and not having a main partner, with trends for greater PrEP use by younger participants and those with partners living with HIV. Among participants not currently on PrEP, strength of PrEP use intentions was associated with higher PrEP knowledge, PrEP descriptive social norms, and PrEP use self-efficacy. This study is among few to directly compare Black who have adopted PrEP with those who have not. Its findings underscore the potential benefits of employing social network approaches for strengthening PrEP use peer norms, increasing PrEP knowledge and self-efficacy, and optimizing PrEP uptake among racial minority MSM and TGW.

HIV risk behavior profiles among men who have sex with men interested in donating blood: Findings from the Assessing Donor Variability and New Concepts in Eligibility study

BACKGROUND

Individual risk assessment allows donors to be evaluated based on their own behaviors. Study objectives were to assess human immunodeficiency virus (HIV) risk behaviors in men who have sex with men (MSM) and estimate the proportion of the study population who would not be deferred for higher risk HIV sexual behaviors.

STUDY DESIGN AND METHODS

Cross-sectional survey and biomarker assessment were conducted in eight U.S. cities. Participants were sexually active MSM interested in blood donation aged 18-39 years, assigned male sex at birth. Participants completed surveys during two study visits to define eligibility, and self-reported sexual and HIV prevention behaviors. Blood was drawn at study visit 1 and tested for HIV and the presence of tenofovir, one of the drugs in oral HIV pre-exposure prophylaxis (PrEP). Associations were assessed between HIV infection status or HIV PrEP use and behaviors, including sex partners, new partners, and anal sex.

RESULTS

A total of 1566 MSM completed the visit 1 questionnaire and blood draw and 1197 completed the visit 2 questionnaire. Among 1562 persons without HIV, 789 (50.4%) were not taking PrEP. Of those not taking PrEP, 66.2% reported one sexual partner or no anal sex and 69% reported no new sexual partners or no anal sex with a new partner in the past 3 months.

CONCLUSION

The study found that questions were able to identify sexually active, HIV-negative MSM who report lower risk sexual behaviors. About a quarter of enrolled study participants would be potentially eligible blood donors using individual risk assessment questions.

Socioecological Analysis of a Nursing Advocacy Skills-Building Activity

BACKGROUND

Advocacy is an expectation of the nursing profession. Nursing curricula should include opportunities for advocacy skills building at multiple levels of potential effect. Analyses of student performances during these advocacy exercises provide insight into how well students understand the multifactorial nature of most public health issues.

METHOD

A socioecological model was used to evaluate nursing students' advocacy responses to food-insecurity scenarios during a guided online discussion activity aimed at advocacy skills building.

RESULTS

Student recommendations were categorized as individual, interpersonal, organizational, community, and policy interventions, with subcategories at each socioecological level.

CONCLUSION

Recommendations are given for future educational research specific to advocacy skills building. Implications for nursing education at each socioecological level also are discussed. [J Nurs Educ. 2023;62(9):509-515.].

Development of An Acceptance Based PrEP Intervention (ACTPrEP) to Engage Young Black MSM in the South Utilizing the Adaptome Model of Intervention Adaptation

Objectives

HIV disproportionately affects young Black men who have sex with men (YBMSM) in the Southern United States. Pre-exposure prophylaxis (PrEP) is an efficacious, biomedical approach to prevent HIV. While Mississippi (MS) has among the highest rates of new HIV infections, it also ranks among the top three states for unmet PrEP need. Thus, increasing engagement in PrEP care for YBMSM in MS is imperative. A potential method to improve psychological flexibility and promote PrEP uptake, explored by this study, is the incorporation of Acceptance and Commitment Therapy (ACT) into PrEP interventions. ACT is an evidence-based intervention used to treat a wide range of mental and physical illnesses.

Methods

Twenty PrEP-eligible YBMSM and ten clinic staff working with YBMSM in MS were surveyed and interviewed between October 2021 and April 2022. The brief survey covered PrEP structural barriers, PrEP stigma, and psychological flexibility. Interview topics included internal experiences related to PrEP, existing health behaviors, PrEP related personal values, and relevant constructs from the Adaptome Model of Intervention Adaptation (service setting, target audience, mode of delivery, and cultural adaptations). Qualitative data were coded based on ACT and the Adaptome model, organized using NVivo, then thematically analyzed.

Results

Patients identified side effects, costs, and taking a daily prescription as top barriers to taking PrEP. Staff reported the top barrier to PrEP for clients was concern others would believe they were living with HIV. Levels of psychological flexibility and inflexibility varied widely among participants. The resulting thematic categories derived from the interviews included 1) thoughts, emotions, associations, memories, and sensations (TEAMS) related to PrEP and HIV, 2) general health behaviors (existing coping techniques, views on medication, HIV/PrEP approach and avoidance), 3) values related to PrEP use (relationship values, health values, intimacy values, longevity values), and 4) Adaptome Model adaptations. These results informed the development of a new intervention, ACTPrEP.

Conclusions

Interview data organized by the Adaptome Model of Intervention Adaptation determined appropriate ACT-informed intervention components, content, intervention adaptations, and implementation strategies. Interventions informed by ACT that help YBMSM endure short-term discomfort related to PrEP by relating it to their values and long-term health goals are promising for increasing individuals' willingness to initiate and maintain PrEP care.

Preferences for PrEP modalities among gay, bisexual, and other men who have sex with men from Brazil, Mexico, and Peru: a cross-sectional study

Background

Pre-exposure prophylaxis (PrEP) scale-up is urgent to reduce new HIV cases among gay, bisexual, and other men who have sex with men (MSM) in Latin America. Different PrEP modalities may increase PrEP uptake and adherence, especially among young MSM.

Objectives

To assess preferences for PrEP modalities among MSM from Brazil, Mexico, and Peru.

Design

Cross-sectional web-based study (March-May 2018) targeting MSM through advertisements on Grindr, Hornet, and Facebook. We included MSM aged ⩾ 18 years and who reported HIV-negative status.

Methods

We assessed preferences for PrEP modalities with the following question: 'Considering that all following PrEP modalities were available, which one would you prefer considering a scale from 1 to 3 (1 = most preferred): daily oral PrEP, event-driven PrEP (ED-PrEP), and long-acting injectable PrEP'. We assessed factors associated with each most preferred PrEP modality per country using multivariable logistic regression models.

Results

A total of 19,457 MSM completed the questionnaire (Brazil: 58%; Mexico: 31%; Peru: 11%); median age was 28 years [interquartile range (IQR): 24-34]. Overall, injectable PrEP was the most preferred modality [42%; 95% confidence interval (CI): 41-43], followed by daily PrEP (35%; 95% CI: 34-35), and ED-PrEP (23%; 95% CI: 23-24). In multivariable models, preferring injectable PrEP was associated with PrEP awareness in all three countries, while PrEP eligibility only in Brazil. Preferring daily PrEP was associated with younger age and lower income in Brazil and Mexico, and lower education only in Brazil. The odds of preferring ED-PrEP were lower among MSM aware and eligible for PrEP in Brazil and Mexico.

Conclusions

Long-acting injectable PrEP was the preferred PrEP modality among MSM in Brazil, Mexico, and Peru, especially those aware and eligible for PrEP. Public health interventions to increase PrEP modalities literacy and availability in Latin America are urgent especially among MSM of young age, lower income, and lower education.

Intention to use PrEP among men who have sex with men and engage in chemsex: an international descriptive study

Background

Pre-exposure prophylaxis (PrEP) is a valuable tool in the response to the HIV epidemic, recommended for groups with a higher risk of HIV infection, such as men who have sex with men (MSM), particularly in the context of high-risk sexual behavior such as chemsex.

Purpose

This study aimed to analyze the prevalence and factors associated with the intention to use PrEP among MSM who engage in chemsex in Brazil and Portugal.

Methods

This was a cross-sectional study of a secondary dataset from a larger study conducted between January 2020 and May 2021 throughout Brazil and Portugal involving 1852 MSM who engage in chemsex. An initial descriptive analysis was performed to calculate the absolute and relative frequencies of independent variables related to the intention to use PrEP among MSM. A multivariate regression model was developed to identify factors independently associated with the intention to use PrEP.

Results

Although a high level of PrEP knowledge (85.75%) was observed among MSM who engage in chemsex, the prevalence of intention to use PrEP was only 59.07%. Five variables were associated with a higher prevalence of intention to use PrEP [engaging in double penetration - adjusted prevalence ratio (aPR): 1.56, 95% CI: 1.44-1.69; being assigned female sex at birth - aPR: 1.34, 95% CI: 1.12-1.61; cruising - aPR: 1.21, 95% CI: 1.06-1.38; not using condoms - aPR: 1.20, 95% CI: 1.05-1.36; and being an immigrant - aPR: 1.16; 95% CI: 1.07-1.25], while having knowledge of postexposure prophylaxis (aPR: 0.91; 95% CI: 0.84-0.98), having a casual sexual partner (aPR: 0.86 and 0.85; 95% CI: 0.74-0.99 and 0.74-0.98), and engaging in group sex (aPR: 0.81; 95% CI: 0.73-0.90) were associated with a lower intention to use PrEP.

Conclusion

The intention to use PrEP among MSM who engage in chemsex was high, and several factors were associated with this intention. Understanding the factors associated with the intention to use PrEP among MSM practicing chemsex is crucial for developing targeted interventions to increase PrEP uptake in this population. The results of this study suggest that tailored approaches are necessary to promote PrEP use in this population.

Suboptimal Follow-Up on HIV Test Results among Young Men Who Have Sex with Men: A Community-Based Study in Two U.S. Cities

Frequent HIV testing and knowledge of HIV serostatus is the premise before timely access to HIV prevention and treatment services, but a portion of young men who have sex with men (YMSM) do not always follow up on their HIV test results after HIV testing, which is detrimental to the implementation of HIV prevention and care among this subgroup. The comprehensive evaluation of factors associated with inconsistent follow-up on HIV test results may inform relevant interventions to address this critical issue among YMSM. To this end, we conducted a cross-sectional study in Nashville, Tennessee and Buffalo, New York from May 2019 to May 2020 to assess demographic, behavioral, and psychosocial correlates of inconsistent follow-up on HIV test results among YMSM. Of the 347 participants, 27.1% (n = 94) reported inconsistent follow-up on their HIV test results. Multivariable logistic regression showed that inconsistent follow-up on HIV test results was positively associated with condomless receptive anal sex, group sex, recreational drug use before or during sex, internalized homophobia, and stress; while negatively associated with housing stability, social support, and general resilience. Future HIV prevention intervention efforts should target these modifiable determinants to enhance the follow-up on HIV test results among YMSM.
