Smartphone-Based Contingency Management Intervention to Improve Pre-Exposure Prophylaxis Adherence: Pilot Trial

A Community Guide Systematic Review: Digital HIV Pre-Exposure Prophylaxis Interventions

INTRODUCTION

HIV preexposure prophylaxis (PrEP) is highly effective when taken as prescribed. Digital health adherence interventions have been identified as effective for improving antiretroviral therapy adherence among people with HIV, but limited evidence exists for PrEP adherence interventions among people without HIV. The purpose of this Community Guide systematic review was to present the characteristics and effectiveness of digital PrEP adherence interventions.

METHODS

The author searched the CDC HIV Prevention Research Synthesis cumulative database for digital health interventions with PrEP adherence outcomes published in peer-reviewed journals from 2000 to 2022. Studies with comparison arms or pre-post data evaluating interventions in high-income countries were included. Two reviewers independently screened citations, extracted data, conducted risk of bias assessment, and resolved discrepancies through discussion. Summary effect estimates were calculated using median and interquartile interval.

RESULTS

Nine studies were included and all focused on gay, bisexual, and other men who have sex with men. Eight studies were U.S.-based while the other was conducted in the Netherlands. Five were randomized control trials and four were pre-/post studies. All studies showed improved adherence in the intervention arms compared with comparison groups or preintervention data. One study also reported improvement in PrEP care retention.

DISCUSSION

Digital health adherence interventions with different strategies to improve PrEP and HIV-related outcomes were identified. The small number of studies identified is a limitation. Findings from this review served as the basis for the Community Preventive Services Task Force recommendation to use these interventions to increase PrEP adherence to prevent HIV infection.

A Systematic Review of Oral Pre-exposure Prophylaxis HIV Adherence Interventions

ABSTRACT

Clinical trials of pre-exposure prophylaxis (PrEP) to prevent HIV infection have established its efficacy as upwards of 99%. Despite this, the effectiveness of this medication has been shown to be diminished by individual factors, such as medication adherence. We completed a systematic review to identify and describe interventions to improve oral PrEP adherence. Overall, 16 articles were located. Two of the articles reported on results from the same trial and were collapsed for analysis, bringing the total to 15 studies. Twelve unique PrEP adherence interventions were tested, with the most common intervention being the use of mobile phone technology, which was used in 7 (46%) of the studies. Ten (67%) studies found that medication adherence improved when participants received an intervention to support adherence. Adherence intervention strategies effectively improved PrEP adherence. Further research into PrEP adherence interventions is warranted, particularly among diverse groups.

Improving Delivery and Use of HIV Pre-Exposure Prophylaxis in the US: A Systematic Review of Implementation Strategies and Adjunctive Interventions

Implementation of pre-exposure prophylaxis (PrEP) to prevent HIV transmission is suboptimal in the United States. To date, the literature has focused on identifying determinants of PrEP use, with a lesser focus on developing and testing change methods to improve PrEP implementation. Moreover, the change methods available for improving the uptake and sustained use of PrEP have not been systematically categorized. To summarize the state of the literature, we conducted a systematic review of the implementation strategies used to improve PrEP implementation among delivery systems and providers, as well as the adjunctive interventions used to improve the uptake and persistent adherence to PrEP among patients. Between November 2020 and January 2021, we searched Ovid MEDLINE, PsycINFO, and Web of Science for peer reviewed articles. We identified 44 change methods (18 implementation strategies and 26 adjunctive interventions) across a variety of clinical and community-based service settings. We coded implementation strategies and adjunctive interventions in accordance with established taxonomies and reporting guidelines. Most studies focused on improving patient adherence to PrEP and most conducted pilot trials. Just over one-third of included studies demonstrated a positive effect on outcomes. In order to end the human immunodeficiency virus (HIV) epidemic in the U.S., future, large scale HIV prevention research is needed that develops and evaluates implementation strategies and adjunctive interventions for target populations disproportionately affected by HIV.

Identifying Best Practices for Increasing HIV Pre-exposure Prophylaxis (PrEP) Use and Persistence in the United States: A Systematic Review

A qualitative systematic review was conducted to evaluate pre-exposure prophylaxis (PrEP) interventions, describe characteristics of best practices for increasing PrEP use and persistence, and explore research gaps based on current PrEP interventions. We searched CDC's Prevention Research Synthesis (PRS) Project's cumulative HIV database (includes CINAHL, EMBASE, Global Health, MEDLINE, PsycInfo, and Sociological Abstracts) to identify PrEP intervention studies conducted in the U.S., published between 2000 and 2022 (last searched January 2023). Eligibility criteria include studies that evaluated PrEP interventions for persons testing negative for HIV infection, or for healthcare providers who prescribed PrEP; included comparisons between groups or pre/post; and reported at least one relevant PrEP outcome. Each eligible intervention was evaluated on the quality of study design, implementation, analysis, and strength of evidence (PROSPERO registration number: CRD42021256460). Of the 26 eligible interventions, the majority were focused on men who have sex with men (n = 18) and reported PrEP adherence outcomes (n = 12). Nine interventions met the criteria for Best Practices (i.e., evidence-based interventions, evidence-informed interventions). Five were digital health interventions while two implemented individual counseling, one offered motivational interviewing, and one provided integrated medical care with a PrEP peer navigator. Longer intervention periods may provide more time for intervention exposure to facilitate behavioral change, and engaging the community when developing, designing and implementing interventions may be key for effectiveness. For digital health interventions, two-way messaging may help participants feel supported. Research gaps included a lack of Best Practices for several populations (e.g., Black persons, Hispanic/Latino persons, persons who inject drugs, and women of color) and evidence for various intervention strategies (e.g., interventions for promoting provider's PrEP prescription behavior, peer support). These findings call for more collaborative work with communities to develop interventions that work and implement and disseminate Best Practices for increasing PrEP use and persistence in communities.

mHealth-Based Gamification Interventions Among Men Who Have Sex With Men in the HIV Prevention and Care Continuum: Systematic Review and Meta-Analysis

Background

In the past few years, a burgeoning interest has emerged in applying gamification to promote desired health behaviors. However, little is known about the effectiveness of such applications in the HIV prevention and care continuum among men who have sex with men (MSM).

Objective

This study aims to summarize and evaluate research on the effectiveness of gamification on the HIV prevention and care continuum, including HIV-testing promotion; condomless anal sex (CAS) reduction; and uptake of and adherence to pre-exposure prophylaxis (PrEP), postexposure prophylaxis (PEP), and antiretroviral therapy (ART).

Methods

We comprehensively searched PubMed, Embase, the Cochrane Library, Web of Science, Scopus, and the Journal of Medical Internet Research and its sister journals for studies published in English and Chinese from inception to January 2024. Eligible studies were included when they used gamified interventions with an active or inactive control group and assessed at least one of the following outcomes: HIV testing; CAS; and uptake of and adherence to PrEP, PEP, and ART. During the meta-analysis, a random-effects model was applied. Two reviewers independently assessed the quality and risk of bias of each included study.

Results

The systematic review identified 26 studies, including 10 randomized controlled trials (RCTs). The results indicated that gamified digital interventions had been applied to various HIV outcomes, such as HIV testing, CAS, PrEP uptake and adherence, PEP uptake, and ART adherence. Most of the studies were conducted in the United States (n=19, 73%). The most frequently used game component was gaining points, followed by challenges. The meta-analysis showed gamification interventions could reduce the number of CAS acts at the 3-month follow-up (n=2 RCTs; incidence rate ratio 0.62, 95% CI 0.44-0.88). The meta-analysis also suggested an effective but nonstatistically significant effect of PrEP adherence at the 3-month follow-up (n=3 RCTs; risk ratio 1.16, 95% CI 0.96-1.38) and 6-month follow-up (n=4 RCTs; risk ratio 1.28, 95% CI 0.89-1.84). Only 1 pilot RCT was designed to evaluate the effectiveness of a gamified app in promoting HIV testing and PrEP uptake. No RCT was conducted to evaluate the effect of the gamified digital intervention on PEP uptake and adherence, and ART initiation among MSM.

Conclusions

Our findings suggest the short-term effect of gamified digital interventions on lowering the number of CAS acts in MSM. Further well-powered studies are still needed to evaluate the effect of the gamified digital intervention on HIV testing, PrEP uptake, PEP initiation and adherence, and ART initiation in MSM.

Pilot Randomized Controlled Trial of Game Plan for PrEP: A Brief, Web and Text Message Intervention to Help Sexual Minority Men Adhere to PrEP and Reduce Their Alcohol Use

Suboptimal adherence to oral PrEP medications, particularly among younger sexual minority men (SMM), continues to be a key barrier to achieving more substantial declines in new HIV infections. Although variety of interventions, including web and text-message-based applications, have successfully addressed PrEP adherence, very few have addressed the potential influence of alcohol. This pilot study explored whether the Game Plan for PrEP, a brief, web-based and text messaging intervention, helped promote PrEP persistence and adherence and reduced condomless sex and alcohol use. Seventy-three heavy-drinking SMM on PrEP were recruited online from states with Ending the HIV Epidemic jurisdictions and randomly assigned 1:1 to receive either the Game Plan for PrEP intervention or an attention-matched control. We collected online surveys assessing primary outcomes at one, three, and six months post-enrollment. As secondary outcomes, we also collected dried blood spot samples at baseline, three, and six months to analyze for biomarkers of PrEP and alcohol use. Our results showed that the odds of stopping PrEP or experiencing a clinically meaningful lapse in PrEP adherence (≥ 4 consecutive missed doses) were not different across the two conditions. We also did not find evidence of any differences in condomless sex or drinking outcomes across conditions, although participants in both conditions reported drinking less often over time. These findings were consistent across both self-reported outcomes and biomarkers. Overall, we did not find evidence that our brief, web and text messaging intervention encouraged more optimal PrEP coverage or moderate their alcohol use.

Provider Perspectives on Multi-level Barriers and Facilitators to PrEP Access Among Latinx Sexual and Gender Minorities

Although pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention intervention, inequities in access remain among Latinx sexual and gender minorities (LSGM). There is also a gap in the PrEP literature regarding providers' perspective on access inequities. This qualitative case study sought to explore barriers and facilitators to PrEP engagement in a community-based integrated health center primarily serving Latinx populations in Northern California. We conducted in-depth, semi-structured interviews with providers (9/15) involved in PrEP services and engaged in a constructivist grounded theory analysis consisting of memoing, coding, and identifying salient themes. Three participants worked as medical providers, three as outreach staff, and one each in planning, education, and research. The analysis surfaced four themes: geopolitical differences, culture as barrier, clinic as context, and patient strengths and needs. Participants referenced a lack of resources to promote PrEP, as well as the difficulties of working within an institution that still struggles with cultural and organizational mores that deprioritize sexual health. Another barrier is related to sexual health being positioned outside of patients' immediate needs owing to structural barriers, including poverty, documentation status, and education. Participants, however, observed that peer-based models, which emboldened their decision-making processes, were conducive to better access to PrEP, as well as allowing them to build stronger community ties. These data underscore the need for interventions to help reduce sexual stigma, promote peer support, and ameliorate structural barriers to sexual healthcare among LSGM.

A Systematic Review of Implementation Research on Determinants and Strategies of Effective HIV Interventions for Men Who Have Sex with Men in the United States

Men who have sex with men (MSM) are disproportionately affected by HIV, accounting for two-thirds of HIV cases in the United States despite representing ∼5% of the adult population. Delivery and use of existing and highly effective HIV prevention and treatment strategies remain suboptimal among MSM. To summarize the state of the science, we systematically review implementation determinants and strategies of HIV-related health interventions using implementation science frameworks. Research on implementation barriers has focused predominantly on characteristics of individual recipients (e.g., ethnicity, age, drug use) and less so on deliverers (e.g., nurses, physicians), with little focus on system-level factors. Similarly, most strategies target recipients to influence their uptake and adherence, rather than improving and supporting implementation systems. HIV implementation research is burgeoning; future research is needed to broaden the examination of barriers at the provider and system levels, as well as expand knowledge on how to match strategies to barriers-particularly to address stigma. Collaboration and coordination among federal, state, and local public health agencies; community-based organizations; health care providers; and scientists are important for successful implementation of HIV-related health innovations.

Feasibility, Acceptability, and Preliminary Efficacy of a Gamified Mobile Health Contingency Management Intervention for PrEP Adherence Among Black MSM

Oral HIV pre-exposure prophylaxis (PrEP) is effective at preventing HIV. However, low adherence is common and undermines these protective effects. This is particularly relevant for groups with disproportionately higher rates of HIV, including Black men who have sex with men (MSM). The current study tested the feasibility, acceptability, and preliminary efficacy of a gamified mobile health contingency management intervention for PrEP adherence-called mSMART (Mobile App-Based Personalized Solutions for Medication Adherence of Rx Pill Tool). Fifteen Black MSM already prescribed PrEP in the community completed baseline and follow-up assessments separated by 8 weeks of using mSMART. Regarding feasibility, there was no study attrition, no mSMART functional difficulties that significantly interfered with use, and a mean rate of 82% daily mSMART use. Acceptability ratings were in the moderately to extremely satisfied range for factors such as willingness to recommend mSMART to others and user-friendliness, and in the low range for ratings on difficulty learning how to use mSMART. Scores on a system usability measure were in the acceptable range for 73% of the sample. Qualitative analysis of follow-up interviews identified individual components of mSMART that could be modified in future iterations to make it more engaging. PrEP composite adherence scores from biomarkers indicated an improvement from baseline to follow-up with a medium effect size, as well as a decrease in the number of perceived barriers to medication adherence. Findings indicate a future efficacy trial is needed to examine the effects of this gamified mobile health contingency management intervention on PrEP adherence.

Applying Behavioural Insights to HIV Prevention and Management: a Scoping Review

PURPOSE OF REVIEW

This scoping review summarises the literature on HIV prevention and management interventions utilizing behavioural economic principles encapsulated in the MINDSPACE framework.

RECENT FINDINGS

MINDSPACE is an acronym developed by the UK's behavioural insights team to summarise nine key influences on human behaviour: Messenger, Incentives, Norms, Default, Salience, Priming, Affect, Commitment, and Ego. These effects have been used in various settings to design interventions that encourage positive behaviours. Currently, over 200 institutionalised behavioural insight teams exist internationally, which may draw upon the MINDSPACE framework to inform policy and improve public services. To date, it is not clear how behavioural insights have been applied to HIV prevention and management interventions. After screening 899 studies for eligibility, 124 were included in the final review. We identified examples of interventions that utilised all the MINDSPACE effects in a variety of settings and among various populations. Studies from high-income countries were most common (n = 54) and incentives were the most frequently applied effect (n = 100). The MINDSPACE framework is a useful tool to consider how behavioural science principles can be applied in future HIV prevention and management interventions. Creating nudges to enhance the design of HIV prevention and management interventions can help people make better choices as we strive to end the HIV/AIDS pandemic by 2030.

Public Health Implications of Adapting HIV Pre-exposure Prophylaxis Programs for Virtual Service Delivery in the Context of the COVID-19 Pandemic: Systematic Review

BACKGROUND

The novel coronavirus disease COVID-19 caused by SARS-CoV-2 threatens to disrupt global progress toward HIV epidemic control. Opportunities exist to leverage ongoing public health responses to mitigate the impacts of COVID-19 on HIV services, and novel approaches to care provision might help address both epidemics.

OBJECTIVE

As the COVID-19 pandemic continues, novel approaches to maintain comprehensive HIV prevention service delivery are needed. The aim of this study was to summarize the related literature to highlight adaptations that could address potential COVID-19-related service interruptions.

METHODS

We performed a systematic review and searched six databases, OVID/Medline, Scopus, Cochrane Library, CINAHL, PsycINFO, and Embase, for studies published between January 1, 2010, and October 26, 2021, related to recent technology-based interventions for virtual service delivery. Search terms included "telemedicine," "telehealth," "mobile health," "eHealth," "mHealth," "telecommunication," "social media," "mobile device," and "internet," among others. Of the 6685 abstracts identified, 1259 focused on HIV virtual service delivery, 120 of which were relevant for HIV prevention efforts; 48 pertained to pre-exposure prophylaxis (PrEP) and 19 of these focused on evaluations of interventions for the virtual service delivery of PrEP. Of the 16 systematic reviews identified, three were specific to PrEP. All 35 papers were reviewed for outcomes of efficacy, feasibility, and/or acceptability. Limitations included heterogeneity of the studies' methodological approaches and outcomes; thus, a meta-analysis was not performed. We considered the evidence-based interventions found in our review and developed a virtual service delivery model for HIV prevention interventions. We also considered how this platform could be leveraged for COVID-19 prevention and care.

RESULTS

We summarize 19 studies of virtual service delivery of PrEP and 16 relevant reviews. Examples of technology-based interventions that were effective, feasible, and/or acceptable for PrEP service delivery include: use of SMS, internet, and smartphone apps such as iText (50% [95% CI 16%-71%] reduction in discontinuation of PrEP) and PrEPmate (OR 2.62, 95% CI 1.24-5.5.4); telehealth and eHealth platforms for virtual visits such as PrEPTECH and IowaTelePrEP; and platforms for training of health care workers such as Extension for Community Healthcare Outcomes (ECHO). We suggest a virtual service delivery model for PrEP that can be leveraged for COVID-19 using the internet and social media for demand creation, community-based self-testing, telehealth platforms for risk assessment and follow-up, applications for support groups and adherence/appointment reminders, and applications for monitoring.

CONCLUSIONS

Innovations in the virtual service provision of PrEP occurred before COVID-19 but have new relevance during the COVID-19 pandemic. The innovations we describe might strengthen HIV prevention service delivery during the COVID-19 pandemic and in the long run by engaging traditionally hard-to-reach populations, reducing stigma, and creating a more accessible health care platform. These virtual service delivery platforms can mitigate the impacts of the COVID-19 pandemic on HIV services, which can be leveraged to facilitate COVID-19 pandemic control now and for future responses.

The Potential of Telecommunication Technology to Address Racial/Ethnic Disparities in HIV PrEP Awareness, Uptake, Adherence, and Persistence in Care: A Review

Pre-exposure prophylaxis (PrEP) is highly effective in preventing new HIV infection, but uptake remains challenging among Black and Hispanic/Latino persons. The purpose of this review was to understand how studies have used electronic telecommunication technology to increase awareness, uptake, adherence, and persistence in PrEP care among Black and Hispanic/Latino persons and how it can reduce social and structural barriers that contribute to disparities in HIV infection. Of the 1114 articles identified, 10 studies were eligible. Forty percent (40%) of studies focused on Black or Hispanic/Latino persons and 80% addressed social and structural barriers related to PrEP use such as navigation or access to PrEP. Mobile health designs were more commonly used (50%) compared to telehealth (30%) and e-health (20%) designs. There is a need to increase the development of telecommunications interventions that address the needs of Black and Hispanic/Latino persons often challenged with uptake and adherent use of PrEP.

Adherence to Pre-Exposure Prophylaxis in Adolescents and Young Adults: A Systematic Review and Meta-Analysis

This meta-analysis synthesized the proportion of adolescents and young adults (AYAs) who are adherent to pre-exposure prophylaxis (PrEP) and factors moderating adherence. A systematic search was conducted of studies published through May 2020 using PubMed, PsycInfo, Cochrane, EMBASE, and CINAHL. Included studies reported the proportion of AYAs (mean age ≤ 29 years) who were PrEP adherent. PrEP adherence was meta-analyzed using random-effects models. Secondary analyses evaluated potential moderating variables. A total of 41 individual samples, from 29 studies, of 8,679 AYA (weighted average age = 23.8 years) were synthesized. The proportion of AYA who met study-defined thresholds for PrEP adherence was .64 (95% confidence interval .57-.71) across studies. Subgroup analyses revealed that adherence was lower in young cisgender women (.46) than young men who have sex with men (.65) and serodiscordant heterosexual couples (.98). Adherence was higher in studies initiated after 2012 (.70) than earlier studies (.47). No differences based on participant age, country, or strategies to promote adherence were found. Across published studies to date, 64% of AYA demonstrate adequate PrEP adherence. Findings can be used to guide PrEP adherence interventions and also provide directions for future research on PrEP among AYA.

Religiosidade/Espiritualidade e Adesão à Terapia Antirretroviral em Pessoas Vivendo com HIV

Resumo Dentre os fatores associados à adesão à Terapia Antirretroviral (TARV) em pessoas vivendo com HIV, destaca-se a religiosidade/espiritualidade (R/E). O objetivo deste estudo foi apresentar as evidências disponíveis sobre a relação entre a dimensão da R/E e a adesão aos antirretrovirais. Realizou-se uma revisão integrativa de literatura com buscas nas bases/bibliotecas CINAHL, LILACS, PePSIC, PsycINFO, PubMed, SciELO, Scopus e Web of Science. Foram selecionados artigos empíricos publicados entre janeiro de 2008 e junho de 2019, sendo recuperados 49 estudos após a aplicação dos critérios de inclusão/exclusão. Encontraram-se associações positivas, negativas e neutras entre R/E e adesão à TARV, evidenciando que a R/E é uma dimensão psicossocial que pode ser preditora da adesão aos antirretrovirais. O sentido dessa influência, no entanto, ainda não é um consenso na literatura científica. Recomenda-se que essas influências sejam compreendidas a partir de elementos contextuais dessa população e não apenas de marcadores pessoais.

Development of a Mobile Health Application for HIV Prevention Among At-Risk Populations in Urban Settings in East Africa: A Participatory Design Approach

Background

There is limited evidence in Africa on the design and development of mobile health (mHealth) applications to guide best practices and ensure effectiveness. A pragmatic trial for HIV pre-exposure prophylaxis roll-out among key populations in Tanzania is needed.

Objective

We present the results of the development of a mobile app (Jichunge) intended to promote adherence to pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) and female sex workers (FSW) in Tanzania.

Methods

A participatory design approach was employed and guided by the information system research framework. MSM and FSW were the target populations. A total of 15 MSM and 15 FSW were engaged in the relevance and design cycles, while the piloting phase included 10 MSM and 20 FSW.

Results

The relevance cycle enabled the description of the existing problem, provided the compatible app features for the target population, and identified the need to develop an mHealth app that provides health services in a stigmatizing and discriminating environment. User involvement in the app’s design and evaluation provided an opportunity to incorporate social, cultural, and community-specific features that ensured usability. In addition, the participants suggested valuable information to inform the app, text message services, medication registration, and chat platform designs.

Conclusions

The participatory design approach in the development of mHealth apps is useful in identifying and validating population-specific functional features, improve usability, and ensuring future health impacts. Through this participatory process, the Jichunge app took end-user needs, perspectives, and experiences into account, eliciting enthusiasm regarding its potential role in supporting pre-exposure prophylaxis adherence for HIV and related behavioral change promotion.

Factors associated with PrEP adherence among MSM living in Jackson, Mississippi

Understanding the determinants of pre-exposure prophylaxis (PrEP) adherence is integral to reducing HIV incidence in the United States, especially for those at highest risk. To this end, the present study explored demographic, psychosocial, and behavioral factors related to adherence among 43 Southern, predominately Black, men who have sex with men (MSM). During the study months, 46% of the sample reported being nonadherent to PrEP. Those with more sexual partners (p = .05), greater self-efficacy for taking PrEP (p = .03), and those who felt condoms were less important (p = .02), were more likely to be adherent to PrEP at six-month follow-up. Further interventions that consider perceived sexual risk, condom use, and adherence self-efficacy are needed to improve PrEP adherence among Southern MSM.

Factors associated with self-reported adherence to daily oral pre-exposure prophylaxis among men who have sex with man and transgender women: PrEP Brasil study

Understanding the factors associated with pre-exposure prophylaxis (PrEP) adherence may help in the development of strategies to support, motivate and sustain PrEP use. This study estimated self-reported adherence, described perceived barriers and facilitators and investigated factors associated with adherence to daily oral PrEP among men who have sex with man (MSM) and transgender women after 1 year of PrEP use in Brazil. PrEP Brasil was a prospective, multicentre, open-label demonstration study with MSM and transgender women at high risk for HIV infection. We used logistic regression to evaluate factors associated with complete adherence (not forgetting to take any pills in the past 30 days) at week 48. Of 338 participants included in this analysis, 60% reported complete adherence to daily oral PrEP at week 48. Perceived barriers and facilitators to daily oral PrEP were reported by 38.2% and 98.5%, respectively. The most reported barrier and facilitator were 'I forgot to take my pills' (19.2%) and 'Associate PrEP with a daily activity/task' (58.6%), respectively. In final multivariable analysis, living in Rio de Janeiro (aOR: 0.38; 95% CI: 0.20-0.73), being transgender women (aOR: 0.22; 95% CI: 0.07-0.73), reporting stimulant use (a OR: 0.40; 95% CI: 0.20-0.80) and having any perceived barriers to daily oral PrEP (aOR: 0.12; 95% CI: 0.07-0.23) were associated with decreased odds of complete adherence. Our findings provide information for developing the best practices to promote PrEP adherence in the Brazilian context.

A systematic review of mHealth interventions for HIV prevention and treatment among gay, bisexual, and other men who have sex with men

The use of mobile health (mHealth) technologies addressing HIV disparities among gay, bisexual, and other men who have sex with men (GBMSM) has increased. A systematic review of mHealth interventions for HIV prevention and treatment among GBMSM was conducted to summarize the current evidence and provide recommendations for future research. PRISMA guidelines were followed (PROSPERO ID: 148452). Studies identified via PubMed, PsychInfo, or Embase were included that (i) were in English, (ii) were published in a peer-reviewed journal prior to July 1, 2019, (iii) presented primary results, (iv) included only GBMSM, and (v) reported the results of an mHealth intervention (e.g., text message, phone/mobile application [app]) to improve HIV prevention or treatment outcomes. Of 1,636 identified abstracts, 16 published studies met inclusion criteria. Eleven studies were conducted in the United States. One study was a fully powered randomized controlled trial (RCT), seven were single-arm pilots with pre-post assessments, four were pilot RCTs, and four tested public health campaigns with post-assessments. Seven developed study-specific apps, five used text messaging, and four used existing social networking apps. Most (81%) targeted prevention outcomes. Nine cited a specific behavioral theory. All studies found that a mHealth approach was feasible and acceptable. All interventions provided evidence of preliminary efficacy or promising trends on primary outcomes. Although mHealth interventions for HIV prevention and treatment appear feasible and acceptable, most published studies are small pilot trials. Additional research assessing the efficacy and mechanisms of mHealth interventions is needed.

Promoting Collaborative Goal Setting for Cancer Prevention Among Primary Care Patients Through mHealth: Mixed Methods Evaluation of a New App

BACKGROUND

Many newly diagnosed cancers are associated with modifiable lifestyle behaviors, such as diet, exercise, smoking cessation, and maintaining a healthy weight. However, primary care providers rarely discuss cancer prevention behaviors with their patients.

OBJECTIVE

This study aims to assess the usability, acceptability, and user engagement of the Healthier Together mobile app, which is designed to promote cancer prevention behaviors among non-Hispanic Black primary care patients, by using social networks and goal-setting theories of behavior change.

METHODS

In an 8-week pilot study, we enrolled primary care patients (N=41) and provided them with a cancer prevention mobile app that allowed them to select, track, and share progress on cancer prevention goals with other users. App usability was assessed using the System Usability Scale. We assessed the app's acceptability by qualitatively analyzing open-ended responses regarding participants' overall experience with the app. We assessed participants' engagement by analyzing the built-in data capture device, which included the number of times participants checked in (out of a maximum of 8) during the study.

RESULTS

The mean age of the 41 participants was 51 years (SD 12), and 76% (31/41) were women. App use data were captured from all participants, and 83% (34/41) completed the exit survey and interview. The mean System Usability Scale score was 87 (SD 12; median 90; IQR 78-95). The analysis of open-ended responses revealed several key themes, and participants complemented the app's ease of use and health behavior-promoting features while also commenting on the need for more feedback and social interactions through the app. On average, participants checked in 5.7 times (SD 2.7) out of 8 possible opportunities. Of the 41 participants, 76% (31/41) checked in during at least 4 of the 8 weeks. Secondary analyses revealed that participants often accomplished their set goals (mean 5.1, SD 2.7) for each week. The qualitative analysis of comments given by participants within the app after each weekly check-in revealed several themes on how the app assisted participants in behavioral change, highlighting that some participants created exercise programs, ate healthier foods, lost a significant amount of weight, and stopped smoking during this study.

CONCLUSIONS

The implementation of a mobile cancer prevention goal-setting app in a primary care setting was feasible, and the app achieved high usability, acceptability, and engagement among participants. User feedback revealed an influence on health behaviors. These findings suggest the promise of the Healthier Together app in facilitating behavioral change to reduce cancer risk among non-Hispanic Black primary care patients.

Integrating HIV Preexposure Prophylaxis With Community-Based Syringe Services for Women Who Inject Drugs: Results From the Project SHE Demonstration Study

INTRODUCTION

To guide future preexposure prophylaxis (PrEP) implementation for women who inject drugs (WWID), a population increasingly represented in new HIV cases in the United States, we present results from a demonstration project integrated within a syringe services program (SSP) in Philadelphia, PA.

METHODS

WWID ≥18 years were educated about and offered 24 weeks of daily PrEP. Participants completed surveys and clinical assessments at baseline and at weeks 1, 3, 12, and 24. We used descriptive statistics to estimate feasibility/acceptability, engagement in the care cascade, HIV/sexually transmitted diseases (STI) and pregnancy, issues of safety/tolerability, and preferences/satisfaction with PrEP services. Multivariable logistic regression with generalized estimating equations was used to identify factors associated with PrEP uptake and retention.

RESULTS

We recruited 136 WWID. Of those, 95 were included in the final sample, and 63 accepted a PrEP prescription at week 1. Uptake was associated with greater baseline frequency of SSP access [adjusted odds ratio (aOR) = 1.85; 95% confidence interval (CI): 1.24 to 2.77], inconsistent condom use (aOR = 3.38; 95% CI: 1.07 to 10.7), and experiencing sexual assault (aOR = 5.89; 95% CI: 1.02, 33.9). Of these 95, 42 (44.2%) were retained at week 24. Retention was higher among women who reported more frequent baseline SSP access (aOR = 1.46; 95% CI: 1.04 to 2.24). Self-reported adherence was high but discordant with urine-based quantification of tenofovir. Baseline STI prevalence was 17.9%; there were 2 HIV seroconversions and 1 pregnancy. Safety/tolerability issues were uncommon, and acceptability/satisfaction was high.

CONCLUSIONS

Integrating PrEP with SSP services is feasible and acceptable for WWID. This suggests that daily PrEP is a viable prevention tool for this vulnerable population.

Mental Health, Social Influences, and HIV Pre-exposure Prophylaxis (PrEP) Utilization Among Men and Transgender Individuals Screening for HIV Prevention Trials

The effects of mental health comorbidities and social support on the HIV pre-exposure prophylaxis (PrEP) care continuum are unknown. We conducted a cross-sectional study of men and transgender individuals, ≥ 18 years-old, with ≥ 2 male or transgender partners, or recent condomless anal intercourse. Surveys assessed demographics, mental health treatment, depressive symptomatology, social support, and PrEP-related social contacts. Logistic regression assessed associations between these factors and PrEP uptake and persistence. Participants (n = 247) were 89% cis-male and 46% African-American. Median age was 27 (IQR:23-33). Thirty-seven percent had ever used PrEP, of whom 18% discontinued use. High depressive symptomology was identified in 11% and 9% were receiving mental health treatment. There were no significant associations between depressive symptoms or mental health treatment on the odds of PrEP uptake or discontinuation. Each additional PrEP contact conferred a greater odds of uptake (aOR:1.24, 95% CI: 1.09-1.42). Network-level targets may produce fruitful interventions to increase PrEP uptake.

Effectiveness, Acceptability, and Feasibility of Digital Health Interventions for LGBTIQ+ Young People: Systematic Review

BACKGROUND

Young people (aged 12-25 years) with diverse sexuality, gender, or bodily characteristics, such as those who identify as lesbian, gay, bisexual, transgender, intersex, or queer (LGBTIQ+), are at substantially greater risk of a range of mental, physical, and sexual health difficulties compared with their peers. Digital health interventions have been identified as a potential way to reduce these health disparities.

OBJECTIVE

This review aims to summarize the characteristics of existing evidence-based digital health interventions for LGBTIQ+ young people and to describe the evidence for their effectiveness, acceptability, and feasibility.

METHODS

A systematic literature search was conducted using internet databases and gray literature sources, and the results were screened for inclusion. The included studies were synthesized qualitatively.

RESULTS

The search identified 38 studies of 24 unique interventions seeking to address mental, physical, or sexual health-related concerns in LGBTIQ+ young people. Substantially more evidence-based interventions existed for gay and bisexual men than for any other population group, and there were more interventions related to risk reduction of sexually transmitted infections than to any other health concern. There was some evidence for the effectiveness, feasibility, and acceptability of these interventions overall; however, the quality of evidence is often lacking.

CONCLUSIONS

There is sufficient evidence to suggest that targeted digital health interventions are an important focus for future research aimed at addressing health difficulties in LGBTIQ+ young people. Additional digital health interventions are needed for a wider range of health difficulties, particularly in terms of mental and physical health concerns, as well as more targeted interventions for same gender-attracted women, trans and gender-diverse people, and people with intersex variations.

Mobile App (UPrEPU) to Monitor Adherence to Pre-exposure Prophylaxis in Men Who Have Sex With Men: Protocol for a User-Centered Approach to Mobile App Design and Development

BACKGROUND

Daily and on-demand pre-exposure prophylaxis (PrEP) has been well demonstrated to effectively prevent HIV acquisition for men who have sex with men (MSM). More than half of the MSM PrEP users in Taiwan prefer on-demand PrEP; however, on-demand PrEP involves a complicated dosing regimen because it requires precoital and postcoital dosing and sex events are hard to anticipate. Although there are a growing number of mobile apps designed to improve access to HIV prevention services and HIV medication adherence, few mobile apps focus on adherence to PrEP or are designed to accommodate a complicated, on-demand PrEP dosing schedule.

OBJECTIVE

The aim of this project is to evaluate the usability of a newly developed mobile app (UPrEPU) to assist MSM PrEP users to self-monitor their adherence to either daily or on-demand PrEP using a user-centered scheme.

METHODS

This research will be conducted in 2 phases: app development and usability study. In the app development phase, we will first conduct formative research with end users and stakeholders through in-depth interviews; the results will provide PrEP users' and PrEP navigators' personas as material used in the app conceptualization stage. PrEP navigators are individuals in the health care system that help HIV-negative individuals who need assistance in accessing PrEP care. A low-fidelity prototype of the app feature will be formatted by applying a participatory design approach to engage PrEP users, designers, and app developers in the design process of the app. Then, a high-fidelity prototype of the app will be developed for the usability study and refined iteratively by the multidisciplinary team and new internal testers. Internal testers include the research team consisting of experts in public health, infectious disease, and industrial design and a close network of the research team that is taking PrEP. In the usability study phase, we will enroll 70 MSM PrEP users and follow them up for 4 months. Usability, feasibility, and effectiveness of adherence monitoring will be evaluated.

RESULTS

Refinement of the UPrEPU app is currently ongoing. The usability study commenced in May 2020.

CONCLUSIONS

The UPrEPU app is one of the first apps designed to help MSM PrEP users to self-manage their PrEP schedule better regardless of dosing modes. With a design-thinking approach and adapting to the cultural context in Taiwan's MSM population, this novel app will have substantial potential to be acceptable and feasible and contribute to the reduction of new HIV infections.

Approaches to Objectively Measure Antiretroviral Medication Adherence and Drive Adherence Interventions

PURPOSE OF REVIEW

Traditional methods to assess antiretroviral adherence, such as self-report, pill counts, and pharmacy refill data, may be inaccurate in determining actual pill-taking to both antiretroviral therapy (ART) or pre-exposure prophylaxis (PrEP). HIV viral loads serve as surrogates of adherence on ART, but loss of virologic control may occur well after decreases in adherence and viral loads are not relevant to PrEP.

RECENT FINDINGS

Pharmacologic measures of adherence, electronic adherence monitors, and ingestible electronic pills all serve as more objective metrics of adherence, surpassing self-report in predicting outcomes. Pharmacologic metrics can identify either recent adherence or cumulative adherence. Recent dosing measures include antiretroviral levels in plasma or urine, as well as emtricitabine-triphosphate in dried blood spots (DBS) for those on tenofovir-emtricitabine-based therapy. A urine tenofovir test has recently been developed into a point-of-care test for bedside adherence monitoring. Cumulative adherence metrics assess adherence over weeks to months and include measurement of tenofovir-diphosphate in peripheral blood mononuclear cells or DBS, as well as ART levels in hair. Electronic adherence monitors and ingestible electronic pills can track pill bottle openings or medication ingestion, respectively. New and objective approaches in adherence monitoring can be used to detect nonadherence prior to loss of prevention efficacy or virologic control with PrEP or ART, respectively.

PrEP discontinuation among Latino/a and Black MSM and transgender women: A need for PrEP support services

Purpose

Disparities persist in HIV infection among Black and Latino men who have sex with men (BLMSM) and Black and Latina transgender women (BLTW). Increasing uptake and subsequent consistent use of pre-exposure prophylaxis (PrEP), an effective biomedical strategy for preventing HIV acquisition, can dramatically reduce HIV incidence in these populations. The purpose of this study was to explore reasons for PrEP discontinuation among BLMSM and BLTW living in Los Angeles County to inform the development of support services for these populations to remain persistent with their PrEP regimen.

Methods

In-depth, semi-structured interviews were conducted with 15 BLMSM and 7 BLTW who reported either temporary or indefinite PrEP discontinuation. A thematic analysis approach was used to analyze qualitative data.

Results

Four themes emerged related to reasons for PrEP discontinuation, including: (1) lower perceived HIV risk related to changes in sexual behavior; (2) structural or logistical barriers (e.g., lapse or loss of health insurance, cost, difficulty navigating complex medical systems); (3) anticipated and experienced medication side effects, with a sub-theme of interactions between PrEP and feminizing hormone medications; and (4) challenges with medication adherence.

Conclusions

PrEP is an important prevention tool for BLMSM and BLTW, particularly during periods of heightened HIV risk. However, both individual (e.g., inability to adhere to medication, changes in HIV sexual risk behaviors) and structural/logistical (e.g., loss of insurance, navigating complex medical systems) factors can cause temporary or indefinite PrEP discontinuation. Additional support services, beyond those offered by medical providers, are needed to help BLMSM and BLTW PrEP users overcome barriers to discontinuation and assist them to remain persistent with their PrEP regimen. We describe potential options for support services such as PrEP case management, expanded PrEP navigation services, or text messaging services.

Pre-exposure Prophylaxis (PrEP) for HIV Prevention Among Men Who Have Sex with Men (MSM): A Scoping Review on PrEP Service Delivery and Programming

Pre-exposure prophylaxis (PrEP) is an evidence-based new biomedical HIV prevention intervention, which involves the pre-emptive use of daily (or event-based) antiretroviral drugs, to reduce risk of HIV acquisition if exposed. PrEP has recently been positioned as an integral prevention tool to reduce HIV acquisition risk among men who have sex with men (MSM) at country-level and within global prevention strategies. Given this global scale up of PrEP, we conducted a scoping review of extant international literature documenting service related perspectives, models and lessons learnt in PrEP programming for MSM. A systematic search of literature was conducted, and restricted to English language records in the timeframe 2008 to February 2019. Eligibility criteria centered on whether studies broadly described PrEP programming and service delivery for MSM as well as health communication. Following exclusion of ineligible records and removal of duplicates, 84 records were charted and thematically analysed according to scoping review methods. Four themes emerged from the thematic analysis of data; 'PrEP service aspects, settings and staff'; 'PrEP prescriber experiences, therapeutic alliance and care planning'; 'PrEP adherence within formal service structures'; and 'Multi-disciplinary and innovative PrEP care pathways'. The review highlights the complexities in providing optimal PrEP services for MSM by mapping and illustrating the importance of understanding the informal and formal routes to PrEP use among this HIV risk population; the barriers to uptake; the requirement for the presence of a positive therapeutic alliance between patient and prescriber in supporting patient initiation and adherence to PrEP regimes; and the need for availability in different culturally and ethnically sensitive models of PrEP service delivery according to low to high risk groups within the MSM communities.

A Review of Usability Evaluation Methods and Their Use for Testing eHealth HIV Interventions

PURPOSE OF REVIEW

To provide a comprehensive review of usability testing of eHealth interventions for HIV.

RECENT FINDINGS

We identified 28 articles that assessed the usability of eHealth interventions for HIV, most of which were published within the past 3 years. The majority of the eHealth interventions for HIV was developed on a mobile platform and focused on HIV prevention as the intended health outcome. Usability evaluation methods included eye-tracking, questionnaires, semi-structured interviews, contextual interviews, think-aloud protocols, cognitive walkthroughs, heuristic evaluations and expert reviews, focus groups, and scenarios. A wide variety of methods is available to evaluate the usability of eHealth interventions. Employing multiple methods may provide a more comprehensive assessment of the usability of eHealth interventions as compared with inclusion of only a single evaluation method.

Youth-friendly services and a mobile phone application to promote adherence to pre-exposure prophylaxis among adolescent men who have sex with men and transgender women at-risk for HIV in Thailand: a randomized control trial

INTRODUCTION

Strategies are needed to curb the increasing HIV incidence in young men who have sex with men (YMSM) and transgender women (YTGW) worldwide. We assessed the impact of youth-friendly services (YFS) and a mobile phone application (app) on adherence to pre-exposure prophylaxis (PrEP) in YMSM and YTGW in Thailand.

METHODS

A randomized control trial was conducted in YMSM and YTGW aged 15 to 19 years. Participants were provided daily oral tenofovir disoproxil fumerate/emtricitabine (TDF/FTC), condoms and randomized to receive either YFS or YFS plus a PrEP app (YFS + APP), whose features included self-assessment of HIV acquisition risk, point rewards and reminders for PrEP and clinic appointments. Clinic visits occurred at zero, one, three and six months and telephone contact at two, four and five months. HIV testing was performed at every clinic visit. PrEP adherence was evaluated with intracellular tenofovir diphosphate (TFV-DP) concentrations in dried blood spot (DBS) samples at months 3 and 6. The primary endpoint assessed was "PrEP adherence" defined as TFV-DP DBS concentrations ≥700 fmol/punch (equivalent to ≥4 doses of TDF/week).

RESULTS

Between March 2018 and June 2019, 489 adolescents were screened at three centres in Bangkok. Twenty-seven (6%) adolescents tested positive for HIV and 200 (41%) adolescents participated in the study. Of these, 147 were YMSM (74%) and 53 YTGW (26%). At baseline, median age was 18 years (IQR 17 to 19), 66% reported inconsistent condom use in the past month. Sexually transmitted infection prevalence was 23%. Retention at six months was 73%. In the YFS + APP arm, median app use duration was three months (IQR 1 to 5). PrEP adherence at month 3 was 51% in YFS and 54% in YFS + APP (p-value 0.64) and at month 6 was 44% in YFS and 49% in YFS + APP (p-value 0.54). No HIV seroconversions occurred during 75 person years of follow-up.

CONCLUSIONS

Youth-friendly PrEP services enabled good adherence among half of adolescent PrEP users. However, the mobile phone application tested did not provide additional PrEP adherence benefit in this randomized trial. Adolescent risk behaviours are dynamic and require adaptive programmes that focus on "prevention-effective adherence."

HIV Prevention Research on Men Who Have Sex With Men: A Scoping Review of Systematic Reviews, 1988-2017

In the United States, men who have sex with men (MSM) are disproportionately affected by HIV. To identify research gaps and inform HIV prevention for MSM, we conducted a scoping review of systematic reviews using CDC's Prevention Research Synthesis database. Eligibility criteria comprised English-language systematic reviews focused on HIV prevention for MSM, published during 1988-2017, and included at least one U.S. primary study. We coded data type, subpopulations, topics, and key findings. To assess study quality, we used the Assessment of Multiple Systematic Reviews (AMSTAR). Among 129 relevant systematic reviews, study quality was high or moderate for 63%. Most common topics were sexual behavior and disease vulnerability. The most frequently mentioned MSM subgroups were HIV-positive, Black or African American, and young. Research gaps include Hispanic/Latino MSM, pre-exposure prophylaxis (PrEP), treatment as prevention, social determinants of health, health disparities, syndemics, and protective factors for sexual health.

Nudging to move: a scoping review of the use of choice architecture interventions to promote physical activity in the general population

Background

Nudges are used to alter lifestyles and thus curb the rise of non-communicable diseases. Physical activity is a core prevention strategy to reduce the burden of non-communicable diseases. This paper aims to (1) give an overview of the scope of interventions using choice architecture techniques to promote physical activity at the population levels and (2) identify research gaps by analysing the different approaches in terms of class and type of intervention used.

Methods

A systematic electronic database search was combined with snowball citation sampling of a starter set of publications to search for studies published through October 2018 reporting interventions to promote physical activity at the population level using choice architecture techniques. The methodology of the Joanna Briggs Institute for Scoping Reviews was applied.

Results

In all, 35 publications were included. Most of the interventions used point-of-choice prompts tested at railway stations, shopping malls and airports (N = 27). Eight studies were online studies. While all studies were aimed at the general population, details, if reported at all, were vague and basic. All studies focused on individual-level lifestyle behaviour. None of the studies attempted to alter population-based lifestyle behaviour. Online and “real-world” approaches were rarely combined. Neither, interventions targeting meso- and macro-level structures nor combinations of individual-level and specific meso- or macro-level interventions were found.

Conclusion

Nudging is in principle an effective approach to promote physical activity within the general population. However, there are large gaps in research. Available opportunities have not yet been exhausted. Further research is needed that is explicitly based on behavioural insights and covering the full range of nudging approaches, particularly focussing on theoretical developments, practical feasibility tests and scale-up activities.

Advancing the HIV Pre-Exposure Prophylaxis Continuum: A Collaboration Between a Public Health Department and a Federally Qualified Health Center in the Southern United States

Uptake of pre-exposure prophylaxis (PrEP) has been limited among black and Latino men who have sex with men (MSM), especially in the southern United States. Public health departments and federally qualified health centers (FQHCs) serving predominantly uninsured populations are uniquely positioned to improve access. We evaluated a novel PrEP collaboration between a public health department and an FQHC in North Carolina (NC). In May 2015, a PrEP program was initiated that included no-cost HIV/sexually transmitted infection screening at a public health department, followed by referral to a colocated FQHC for PrEP services. We profiled the PrEP continuum for patients entering the program until February 2018. PrEP initiators and noninitiators were compared using Wilcoxon rank-sum test for continuous variables and chi-square or Fisher's exact tests for categorical variables. Of 196 patients referred to the FQHC, 60% attended an initial appointment, 43% filled a prescription, 38% persisted in care for >3 months, and 30% reported >90% adherence at follow-up. Among those presenting for initial appointments (n = 117), most were MSM (n = 95, 81%) and black (n = 62, 53%); 21 (18%) were Latinx and 9 (8%) were trans persons. Almost half (n = 55) were uninsured. We found statistically significant differences between PrEP initiators versus noninitiators based on race/ethnicity (p = 0.02), insurance status (p = 0.05), and history of sex work (p = 0.05). In conclusion, this collaborative model of PrEP care was able to reach predominantly black and Latino MSM in the southern United States. Although sustainable, program strategies to improve steps along the PrEP care continuum are vital in this population.

Considerations for Implementing Contingency Management in Substance Abuse Treatment Clinics: The Veterans Affairs Initiative as a Model

Contingency management (CM) is an efficacious intervention for the treatment of substance use disorders that is widely applicable across a range of client populations and characteristics. Despite its strong evidence base, CM remains underutilized in real world practice. This article introduces CM for clinicians interested in adopting CM and briefly reviews this research evidence. In addition, CM protocols are described, with emphasis on the specific design considerations important to CM's efficacy. The recent Department of Veterans Affairs (VA) initiative, which represents the first successful large-scale implementation effort, is presented. It provides a model for the training and supervision components that may be critical to implementation with fidelity. Continued research in this area, as well as further demonstrations of successful dissemination and implementation, will be critical for improving the adoption of this intervention in clinical, nonresearch settings.
