Mobile Health Intervention to Reduce HIV Transmission: A Randomized Trial of Behaviorally Enhanced HIV Treatment as Prevention (B-TasP)

Effects of telehealth-assisted interventions among people living with HIV/AIDS: A systematic review and meta-analysis of randomized controlled studies

INTRODUCTION

Taking antiretroviral therapy (ART) is a daily necessity for people living with HIV but these individuals experience multiple barriers and challenges to medication adherence. Interventions to support medication adherence have yielded effects in the expected direction, but the extent to which telehealth or virtually delivered interventions to promote adherence are effective among people living with HIV/AIDS remains unknown. We aimed to address this knowledge gap and inform future research and practice that promotes the well-being of people living with HIV/AIDs through telehealth interventions addressing medication use.

METHODS

A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted using the following databases: Academic Search Complete, Cochrane library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, MEDLINE, PubMed, OVID (UpToDate), and the Web of Science. Relevant full-text articles published through September 2021 were retrieved. The revised Cochrane risk of bias tool for randomized trials was used to assess the methodological quality of the included studies. A meta-analysis was performed using a random-effects model to calculate the pooled effects of telehealth-assisted interventions for people living with HIV/AIDS. Stata 16.0 was used for statistical analysis.

RESULTS

A total of 12 studies (N = 3557 participants) that used telehealth-assisted interventions for people living with HIV/AIDS were included. Telehealth interventions were found to increase the adherence to treatment (standardized mean difference [SMD]: 0.21; 95% confidence interval (CI): 0.03 to 0.40), to reduce depressive symptoms (SMD: -2,74; 95% CI: -3.39 to -2.09), and to improve perceived quality of life (SMD: 0.74; 95% CI: 0.37 to 1.10).

DISCUSSION

The meta-effects of telehealth-assisted interventions include significantly enhanced adherence to treatment, improved quality of life, and reduced depressive symptoms among people living with HIV/AIDS. These findings suggesting that delivering health management interventions remotely through telehealth-assisted modalities was both feasible and effective in yielding health benefits for people living with HIV/AIDS. Integrating telehealth-assisted interventions as a modality in HIV/AIDS care might support continuity of care and sustained well-being. Future research should evaluate telehealth intervention outcomes and examine mediating, moderating, or other tailorable variables affecting intervention effectiveness.

B-OK: A Visual and Tactile Tool for HIV Treatment Adherence Support in a United States Urban Center

Lack of adherence to antiretroviral therapy (ART) and poor retention in care are significant barriers to ending HIV epidemics. Treatment adherence support (TAS) effectiveness may be constrained by limited awareness and understanding of the benefits of ART, particularly the concepts of treatment as prevention and Undetectable=Untransmittable (U=U), for which substantial knowledge gaps persist. We used mixed methods to evaluate a straightforward visual and tactile tool, the B-OK Bottles ("B-OK"), that incorporates human-centered design and behavioral economics principles and is designed to change and strengthen mental models about HIV disease progression and transmission. We enrolled 118 consenting adults living with HIV who were clients of medical case managers at one of four case management agencies in Philadelphia. All participants completed a pre-intervention survey, a B-OK intervention, and a post-intervention survey. A subset (N=52) also completed qualitative interviews before (N=20) or after (N=32) B-OK. Participants had a median age of 55 years (IQR 47-60), about two-thirds were male sex (N=77, 65%), nearly three-quarters identified as non-Hispanic Black (N=85, 72%), and almost all reported receiving ART (N=116, 98%). Exposure to B-OK was associated with improved awareness and understanding of HIV terminology, changes in attitudes about HIV treatment, and increased intention to rely on HIV treatment for transmission prevention. Insights from qualitative interviews aligned with the quantitative findings as respondents expressed a better understanding of U=U and felt that B-OK clearly explained concepts of HIV treatment and prevention. These findings provide a strong rationale to further evaluate the potential for B-OK to improve TAS for PLWH.

A Trauma-Informed HIV Intervention (LinkPositively) to Improve HIV Care Among Black Women Affected by Interpersonal Violence: Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

Black women bear a disproportionate burden of HIV, accounting for nearly 60% of new diagnoses among US women. Black women living with HIV often experience mutually reinforcing epidemics, known as syndemics, including interpersonal violence and substance use. Syndemics are associated with decreased HIV care engagement and treatment adherence and worsening HIV outcomes. Few HIV services and resources are tailored to be culturally and gender-responsive and trauma informed for Black women living with HIV. Technology-based, psychoeducational, and peer navigation programs offer promising pathways to tailored HIV support and improved HIV care outcomes. Therefore, the web-based, trauma-informed intervention LinkPositively was developed in collaboration with Black women living with HIV to promote uptake of HIV care and ancillary support services.

OBJECTIVE

This study primarily determines the feasibility and acceptability of the LinkPositively intervention among Black women living with HIV affected by interpersonal violence. The secondary aim is to examine the preliminary impact of the LinkPositively intervention on retention in HIV care, antiretroviral therapy adherence, and viral suppression while evaluating the role of mechanism of change variables (eg, social support) in the associations.

METHODS

The LinkPositively trial is a pilot randomized controlled trial conducted in California, United States, among 80 adult Black women living with HIV who have experienced interpersonal violence. Core components of LinkPositively include one-on-one peer navigation with phone and SMS text message check-ins; 5 weekly one-on-one video sessions to build coping and care navigation skills; and a mobile app that contains a peer support social networking platform, an educational database with healthy living and self-care tips, a GPS-enabled HIV and ancillary care resource locator, and a medication self-monitoring and reminder system. Participants are randomly assigned to the intervention (n=40) or control (Ryan White standard of care; n=40) arm, with follow-up at 3 and 6 months. At each assessment, participants complete an interviewer-administered survey and submit hair samples for the assessment of HIV medication adherence. All research staff and investigators adhere to ethical principles and guidelines for conducting research activities. Data will be analyzed using generalized estimating equations.

RESULTS

Final development and testing of the LinkPositively app were completed in July 2021. As of May 2023, we have screened 97 women for eligibility. Of the 97 women screened, 27 (28%) were eligible and have been enrolled in the study. The dissemination of preliminary results will occur in 2024.

CONCLUSIONS

This trial will advance HIV prevention science by harnessing technology to promote engagement in HIV care while improving social support through peers and social networking-all while being trauma informed for Black women living with HIV with experiences of interpersonal violence. If shown to be feasible and acceptable, LinkPositively has the potential to improve HIV care outcomes among Black women, a marginalized key population.

Leveraging mHealth for the Treatment and Management of PLHIV

Objective

The objective of this systematic review was to analyze published literature from the last five years to assess facilitators and barriers to the adoption of mHealth as interventions to treat and manage HIV for PLHIV (people living with HIV). The primary outcomes were physical and mental conditions. The secondary outcomes were behavior based (substance use, care engagement, and healthy habits).

Methods

Four databases (PubMed, CINAHL, Web of Science, and ScienceDirect) were queried on 9/2/2022 for peer-reviewed studies on the treatment and management of PLHIV with mHealth as the intervention. The review was conducted in accordance with the Kruse Protocol and reported in accordance with PRISMA 2020.

Results

Five mHealth interventions were identified across 32 studies that resulted in improvements in physical health, mental health, care engagement, and behavior change. mHealth interventions offer both convenience and privacy, meet a digital preference, increase health knowledge, decrease healthcare utilization, and increase quality of life. Barriers are cost of technology and incentives, training of staff, security concerns, digital literacy gap, distribution of technology, technical issues, usability, and visual cues are not available over the phone.

Conclusion

mHealth offers interventions to improve physical health, mental health, care engagement, and behavior for PLHIV. There are many advantages to this intervention and very few barriers to its adoption. The barriers are strong, however, and should be addressed through policy. Further research should focus on specific apps for younger versus older PLHIV, based on preferences and the digital literacy gap.

Addressing Health Inequities in Digital Clinical Trials: A Review of Challenges and Solutions From the Field of HIV Research

Clinical trials are considered the gold standard for establishing efficacy of health interventions, thus determining which interventions are brought to scale in health care and public health programs. Digital clinical trials, broadly defined as trials that have partial to full integration of technology across implementation, interventions, and/or data collection, are valued for increased efficiencies as well as testing of digitally delivered interventions. Although recent reviews have described the advantages and disadvantages of and provided recommendations for improving scientific rigor in the conduct of digital clinical trials, few to none have investigated how digital clinical trials address the digital divide, whether they are equitably accessible, and if trial outcomes are potentially beneficial only to those with optimal and consistent access to technology. Human immunodeficiency virus (HIV), among other health conditions, disproportionately affects socially and economically marginalized populations, raising questions of whether interventions found to be efficacious in digital clinical trials and subsequently brought to scale will sufficiently and consistently reach and provide benefit to these populations. We reviewed examples from HIV research from across geographic settings to describe how digital clinical trials can either reproduce or mitigate health inequities via the design and implementation of the digital clinical trials and, ultimately, the programs that result. We discuss how digital clinical trials can be intentionally designed to prevent inequities, monitor ongoing access and utilization, and assess for differential impacts among subgroups with diverse technology access and use. These findings can be generalized to many other health fields and are practical considerations for donors, investigators, reviewers, and ethics committees engaged in digital clinical trials.

Leaving No One Behind: Human Rights and Gender as Critical Frameworks for U=U

Experience has shown the need to explicitly address human rights and gender-related barriers in the rollout of HIV-related biomedical innovations, including "undetectable equals untransmittable" (U=U). This paper brings to light rights and gender considerations relevant to supporting U=U, recognizing a range of barriers that remain to be addressed for all people to benefit equally from U=U. We conducted a literature review to ascertain how human rights and gender were addressed in relevant publications, including peer-reviewed articles published between 2006 and 2020, relevant nongovernmental and global organizations' publications, and abstracts presented at the 2019 International AIDS Conference, that explicitly addressed U=U or "treatment as prevention." Despite evidence to illustrate the importance of attention to human rights and gender within U=U policies and interventions, there remains a lack of explicit attention to human rights and gender considerations in research and programming, particularly with regard to the rights principles of participation and accountability. Explicitly engaging all of these dimensions is key to informing interventions and improving people's lives, health, and well-being.

Busting contraception myths and misconceptions among youth in Kwale County, Kenya: results of a digital health randomised control trial

OBJECTIVES

The objective of this randomised controlled trial in Kenya was to assess the effect of delivering sexual and reproductive health (SRH) information via text message to young people on their ability to reject contraception-related myths and misconceptions.

DESIGN AND SETTING

A three-arm, unblinded randomised controlled trial with a ratio of 1:1:1 in Kwale County, Kenya.

PARTICIPANTS AND INTERVENTIONS

A total of 740 youth aged 18-24 years were randomised. Intervention arm participants could access informational SRH text messages on-demand. Contact arm participants received once weekly texts instructing them to study on an SRH topic on their own. Control arm participants received standard care. The intervention period was 7 weeks.

PRIMARY OUTCOME

We assessed change myths believed at baseline and endline using an index of 10 contraception-related myths. We assessed change across arms using difference of difference analysis.

RESULTS

Across arms, <5% of participants did not have any formal education, <10% were living alone, about 50% were single and >80% had never given birth. Between baseline and endline, there was a statistically significant drop in the average absolute number of myths and misconceptions believed by intervention arm (11.1%, 95% CI 17.1% to 5.2%), contact arm (14.4%, 95% CI 20.5% to 8.4%) and control arm (11.3%, 95% CI 17.4% to 5.2%) participants. However, we observed no statistically significant difference in the magnitude of change across arms.

CONCLUSIONS

We are unable to conclusively state that the text message intervention was better than text message 'contact' or no intervention at all. Digital health likely has potential for improving SRH-related outcomes when used as part of multifaceted interventions. Additional studies with physical and geographical separation of different arms is warranted.

Changing Knowledge and Attitudes Towards HIV Treatment-as-Prevention and "Undetectable = Untransmittable": A Systematic Review

People on HIV treatment with undetectable virus cannot transmit HIV sexually (Undetectable = Untransmittable, U = U). However, the science of treatment-as-prevention (TasP) may not be widely understood by people with and without HIV who could benefit from this information. We systematically reviewed the global literature on knowledge and attitudes related to TasP and interventions providing TasP or U = U information. We included studies of providers, patients, and communities from all regions of the world, published 2008–2020. We screened 885 papers and abstracts and identified 72 for inclusion. Studies in high-income settings reported high awareness of TasP but gaps in knowledge about the likelihood of transmission with undetectable HIV. Greater knowledge was associated with more positive attitudes towards TasP. Extant literature shows low awareness of TasP in Africa where 2 in 3 people with HIV live. The emerging evidence on interventions delivering information on TasP suggests beneficial impacts on knowledge, stigma, HIV testing, and viral suppression.

Undetected anogenital sexually transmitted infections among young adults living with HIV and receiving antiretroviral therapy: Implications for HIV treatment as prevention

Undetected sexually transmitted infections (STIs) pose health threats to people living with HIV and when combined with uncontrolled HIV can amplify HIV transmission. The current study screened 174 self-identified men under age 36 living with HIV and receiving antiretroviral therapy (ART) for urethral and rectal incident chlamydia and gonorrhea infections. Participants were also screened for biomarkers indicating alcohol and other drug use, subclinical genital inflammation, and HIV viral load. ART adherence and sexual behaviors were also assessed prospectively over 1 month. Results detected an undiagnosed STI in 32 (18%) individuals. Participants with a previously undetected STI had significantly greater HIV viremia than those who did not have an STI after controlling for several confounding variables. Participants with an undetected STI also engaged in greater condomless anal intercourse with HIV negative and unknown status partners, including partners to whom they had not disclosed their HIV status. These findings show that undetected STI are associated with incomplete ART adherence and unsuppressed HIV, all of which are important for preventing HIV transmission.

Undisclosed HIV Status to Sex Partners and Its Unintended Consequences in the Era of Undetectable = Untransmittable

BACKGROUND

Adherence to antiretroviral therapy (ART) and sustained HIV suppression virtually eliminate HIV transmission, eg, having an undetectable viral load renders HIV untransmittable (U=U). Owing to the greatly reduced likelihood of HIV transmission when viral load is undetectable, we studied one behavioral ramification of adopting a U=U prevention strategy-not disclosing HIV status to sex partners.

SETTING

Cisgender men recruited through community outreach in the state of Georgia, USA.

METHODS

We examined HIV status disclosure to sex partners among 345 young (median age = 29 years) men receiving ART. Data were collected using computerized interviews, daily sexual behavior surveys over 28 days, unannounced pill counts for ART adherence, urine tests for drug use and urogenital health, and blood samples for HIV viral load.

RESULTS

One in 3 participants (34%) engaged in condomless anal/vaginal intercourse with an HIV-negative/unknown HIV status partner over 28 days. Average ART adherence was 76%, and one in 5 men had detectable HIV viral loads. Men who engaged in condomless sex with undisclosed partners demonstrated significantly less HIV disclosure to family and friends and had fewer enacted stigma experiences. Hierarchical regression models showed that endorsing U=U as a personal HIV prevention strategy predicted undisclosed condomless sex over and above substance use, HIV stigma experiences, disclosure to family and friends, ART adherence, and HIV viral load.

CONCLUSIONS

Interventions are needed to improve ART adherence and assist men living with HIV in their decisions to disclose HIV status to sex partners.

Efficacy of Psychological Interventions Towards the Reduction of High-Risk Sexual Behaviors Among People Living with HIV: A Systematic Review and Meta-analysis, 2010-2020

People living with HIV/AIDS (PLWH) may be vulnerable to mental illness. As sexual transmission is the leading cause of HIV infection, evidence-based study for the effect of psychological interventions on the change of sexual is needed. To estimate the efficacy of psychological interventions towards reducing unprotected sex and increasing condom use among PLWH. We systematically searched PubMed, Web of Science, EMBASE (OVID), and PsycINFO (OVID) for studies reporting psychological intervention effects on the outcomes of condom use and/or unprotected sex from 2010 to 2020. This review is registered with PROSPERO, CRD42020193640. Of 949 studies, 17 studies were included in this systematic review. Overall, participants in the intervention group reduced sexual risk or condomless sex relative to control groups. The effect was higher for people having sex with HIV-positive partners comparing with those who had sex with HIV-negative or unknown status partners. Psychological interventions might positively affect the condom use of PLWH and should be prioritized and regularly.

Perceived efficacy of HIV treatment-as-prevention among university students in Johannesburg, South Africa

Objective

Antiretroviral therapy (ART) nearly eliminates HIV transmission. Yet information on treatment as prevention (TasP) has been slow to diffuse in sub-Saharan Africa. We assessed TasP knowledge among university students in South Africa.

Methods

We conducted a cross-sectional survey of first-year university students at a large public university in Johannesburg, South Africa, all of whom would have recently completed secondary school HIV curricula. Respondents were asked to consider the likelihood of HIV transmission in a serodiscordant couple having condomless sex with and without virally suppressive ART. Beliefs were elicited using a 0–20 visual scale. Perceived TasP efficacy was computed as the relative reduction in risk associated with virally suppressive ART. We compared beliefs with estimates from the scientific literature and assessed associations with demographics, HIV testing history and qualitative measures of HIV knowledge and risk perception.

Results

The analysis included 365 university students ages 18-25 years (48% female, 56% from Gauteng Province). On average, perceived annual risk of HIV transmission with virally suppressive ART was 73%; the objective risk is <1%. On average, respondents perceived that virally suppressive ART reduced annual transmission risk by 17%; the objective reduction in risk is >96%. We observed no differences in perceived TasP efficacy by participant characteristics and testing history. Perceived TasP efficacy was correlated with the (correct) belief that HIV risk increases with sexual frequency.

Conclusions

University students in South Africa underestimated the prevention benefits of HIV treatment. Low knowledge of TasP could limit demand for HIV testing and treatment among young adults.

LinkPositively: A Trauma-Informed Peer Navigation and Social Networking WebApp to Improve HIV Care among Black Women Affected by Interpersonal Violence

In the U.S., Black women living with HIV/AIDS (WLHA) are affected disproportionately by interpersonal violence, which often co-occurs with adverse mental health and/or substance use, and exacerbates existing poor HIV care outcomes. Peer navigation has been successful in improving HIV care; however, HIV clinics often lack resources for sustainability and may not account for socio-structural barriers unique to Black WLHA. To address this gap, we developed LinkPositively, a culturally-tailored, trauma-informed WebApp for Black WLHA affected by interpersonal violence to improve HIV care outcomes. Using focus group data from nine Black WLHA and peer navigators, we developed LinkPositively. Core components include: virtual peer navigation to facilitate skill-building to cope with barriers and navigate care; social networking platform for peer support; educational and self-care tips; GPS-enabled resource locator for HIV care and support service agencies; and medication self-monitoring/reminder system. If efficacious, LinkPositively will shift the HIV prevention and care paradigm for Black WLHA.

Sexually transmitted infections among women living with HIV in a Brazilian city

Background

Clinical improvements following highly active antiretroviral therapy (HAART) may increase high-risk behaviors resulting in sexually transmitted infections (STI). Optimism related to the success of HAART in slowing disease progression, reducing viral load, and improving health status might be important factors for increasing sexual risk behaviors such as less use of condoms.

Objective

To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, syphilis, hepatitis B and C, high-risk HPV, and cervical cytological abnormalities among women living with HIV (WLHIV) who attended a Reference Center for STI/AIDS in Brazil.

Methods

A cross-sectional study was conducted among 151 WLHIV attending an STI Clinic in Vitória city, Brazil. A structured questionnaire, including demographic, behavioral, and clinical information, was used for data collection. Serological tests for HIV, syphilis, hepatitis C and B, CD4 counts, and viral load determination were performed. Cervical samples were collected for cytology and real-time PCR for HPV,Chlamydia, and Neisseria gonorrhoeae.

Results

In this study, 59% of women had at least one diagnosed STI at the time of the first clinic visit; 31% had clinical forms of anogenital HPV, 10% syphilis, 8%Neisseria gonorrhoeae, 5.0% trichomoniasis, 3% Chlamydia trachomatis, 1% hepatitis B, and 1% hepatitis C; 6.7% of the women presented with cervical cytological abnormalities. Furthermore, 46.3% of women had HR-HPV, and 17.6% had HPV 16/18. Only 5% of the women had a CD4 count <200 cells/mm³, 61.6% had undetectable HIV viral load, and 81.3% were currently on HAART.

Conclusion

A high prevalence of STI and HR-HPV infections were observed among HIV-infected women in this investigation. Prevention programs need to focus on counseling WLHIV and their regular partners with focused interventions such as couples counseling and education programs.

Drug Use and Life Chaos as Potential Factors Contributing to HIV Viral Load among People with Lower Health Literacy

Lower health literacy is associated with poorer health outcomes in people living with HIV (PLWH), but the explanatory mechanisms for these associations are not well understood. Factors such as drug use and life chaos may at least in part account for the relationship between lower health literacy and poor health outcomes. The current study tested the hypothesis that lower health literacy would predict drug use, which in turn would predict life chaos, and that all three factors would be related to poorer heath, defined by higher concentrations of HIV viremia. Methods: Patients receiving HIV care (N = 251) at an HIV clinic in the southeastern United States completed computerized interviews and permission to access their medical records. Process modeling tested direct and indirect effects of all variables in a serial mediation model. Results: The direct effects of lower health literacy and drug use were significantly related to HIV viremia. In addition, the indirect effect of health literacy on HIV viremia through drug use was significant. However, results did not demonstrate any effect, direct or indirect, of life chaos on HIV viremia. Conclusion: Findings from this study bolster previous research demonstrating lower health literacy and drug use as barriers to HIV care, and show that lower health literacy impacts HIV viremia, at least in part, through drug use. Interventions aimed to improve HIV treatment outcomes in lower health literacy populations may be enhanced by integrating evidence-based approaches to reducing drug use.

A New Era of HIV Risk: It's Not What You Know, It's Who You Know (and How Infectious)

HIV is transmitted in social and sexual relationships, and HIV transmission risks, as well as protective actions, are evolving as HIV epidemics unfold. The current focus of HIV prevention is centered on antiretroviral medications used to reduce HIV infectiousness in persons already infected with HIV [treatment as prevention (TasP)]. The same medications used to treat infected persons can also be used by uninfected persons as pre-exposure prophylaxis (PrEP) to reduce the infectivity of HIV. Both PrEP and TasP are effective when adherence is high and individuals do not have co-occurring sexually transmitted infections. HIV prevention is most effective and efficient when delivered within sexual networks with high HIV prevalence. Specific network characteristics are recognized as important facilitators of HIV transmission; these characteristics include the degree of similarity among network members (homophily), gender role norms, and belief systems. Since 2011, HIV risk has been redefined based on infectiousness and infectivity, ushering in a new era of HIV prevention with the potential to end HIV epidemics.
