A Peer-Led HIV Medication Adherence Intervention Targeting Adults Linked to Medical Care but without a Suppressed Viral Load

Social networks and HIV treatment adherence among people with HIV initiating treatment in rural Uganda and peri-urban South Africa

Timely initiation of and adherence to antiretroviral therapy (ART) is critical for improving HIV outcomes and reducing HIV transmissibility. Social networks, or the social relationships individuals have with each other, have been linked with positive health outcomes, but less is known about the extent to which social network composition and structure are associated with improved ART adherence among people living with HIV (PLWH). We conducted an ego-centric network study among 828 previously ART-naïve PLWH presenting for ART initiation at 11 clinics in Mbarara, Uganda (rural population) and Gugulethu, South Africa (peri-urban population). We collected social network data using name generator and name interpreter questions. ART adherence was monitored over 12 months using wireless monitors (Wisepill). Our primary outcome of interest was ART adherence during the 12-month follow-up period. We used generalized linear models to estimate the associations between network measures and ART adherence. PLWH at the Uganda site (compared with the South Africa site) were less isolated, had larger social networks, and had more social ties providing sufficient social support; they were also more likely to bridge different social groups whereby not all social ties were connected to each other. In Uganda, social isolation was associated with a 5.5 percentage point reduction in ART adherence (95% confidence interval [CI] -9.95 to -1.13; p = 0.014), while having more same gender social ties was associated with higher ART adherence (b = 0.13, 95% CI 0.02-0.25, p = 0.025). In South Africa, there was no association between social isolation and ART adherence, and having more friendship ties (vs. family ties) was associated with lower ART adherence (b = -2.20, 95% CI -3.56 to -0.84; p = 0.002). Identifying and supporting PLWH who are isolated may facilitate optimal adherence, but understanding how networks differentially affect ART adherence by country context is important.

Trends in U.S. HIV Peer Health Worker Training Strategies and Approaches: A Scoping Review of the Literature

ABSTRACT

Peer health workers (peers) are commonly engaged interventionists in the HIV care spectrum. The objective of this scoping review was to examine the range of evidence on training strategies and approaches for peer-led HIV behavioral interventions in the United States. Four electronic databases (Medline, CINAHL, EMBASE, and PsycINFO) were searched for peer-reviewed published literature (2010-2021) of peer-led HIV behavioral interventions directed to improving antiretroviral therapy adherence and/or retention in care. Eighteen studies met the inclusion criteria. Eleven studies referenced manualized training materials, and nine used role-play as part of their curricula. Peer training content and duration varied across studies, as well as evaluation of intervention fidelity, and peer competency. Findings highlight heterogeneity in peer training strategies and approaches. The expansion and sustainability of peer engagement in the HIV care continuum will require greater consensus among members of the research community on best practices for training.

Feasibility and Acceptability of the Adherence Connection Counseling, Education, and Support (ACCESS) Proof of Concept: A Peer-Led, Mobile Health (mHealth) Cognitive Behavioral Antiretroviral Therapy (ART) Adherence Intervention for HIV-Infected (HIV+) Adolescents and Young Adults (AYA)

Effective antiretroviral therapy (ART) adherence strategies for HIV+ adolescents and young adults (AYA) are needed to prevent HIV-related morbidity, mortality, and onward transmission. In the Adherence Connection for Counseling, Education, and Support (ACCESS) pilot, an exploratory sequential mixed-methods design was used to develop and test a peer-led, mobile health (mHealth) cognitive behavioral ART adherence intervention. HIV+ AYA (ages 16-29 years) with unsuppressed plasma HIV RNA (HIV viral load) were eligible for this five-session intervention directed to improving ART adherence and HIV viral load. A total of 78 peer-led remote videoconferencing sessions (via WebEx) were delivered to 16 participants. High completion rates (97.5%) and client satisfaction scores (mean = 29.13 of 32; SD = 2.45) were observed. Self-reported ART adherence improved (32% increase in doses taken; 95th CI 11.2-53.3) with an annualized average rate of 47.5% (0.28 log10) reduction in HIV viral load. We established proof of concept for the ACCESS peer-led, mHealth cognitive behavioral ART adherence intervention, with promising adherence and virologic outcome data.

The mediating role of social support between HIV stigma and sexual orientation-based medical mistrust among newly HIV-diagnosed gay, bisexual, and other men who have sex with men

HIV-related stigma and medical mistrust are significant challenges to addressing HIV inequities among gay, bisexual, and other men who have sex with men (MSM). HIV-related stigma is associated with high levels of medical mistrust, but there is limited knowledge regarding the mechanisms that link these variables. We examined the potential mediating roles of social support and coping in the relationship between perceived HIV stigma and sexual orientation based-medical mistrust among newly HIV-diagnosed MSM. We hypothesized that HIV-related stigma would be associated with mistrust and that social support, and coping would mediate this relationship. Data were obtained from 202 newly HIV-diagnosed (<1 year) MSM receiving care at community HIV clinics in New York. A path model indicated that HIV stigma was directly related to greater sexual orientation based medical mistrust, and that this relationship was mediated by social support. However, coping did not mediate the relationship between HIV stigma and mistrust. Efforts to increase social support and decrease stigma are critical for strengthening relationships between MSM and HIV care networks. Future research should assess the feasibility of designing and implementing interventions focused on increasing social network support and improving trust in the medical community among newly HIV-diagnosed MSM.

The effectiveness and sustainability of peer support interventions for persons living with HIV: a realist synthesis

BACKGROUND

Peer support is an important supplement to medical resources for persons living with HIV (PLHIV). However, previous studies have shown mixed results about intervention effects. It is necessary to explain the mechanism of peer support interventions' effectiveness and sustainability to help design more valid peer support interventions.

OBJECTIVE

To identify and explain the mechanisms that drive the effectiveness and maintain the sustainability of peer support interventions.

METHODS

A preliminary theoretical framework was developed through a scoping review of the grey literature and international project frameworks in five professional websites. We then refined the framework by systematically searching evidence in databases including PubMed, EMBASE, Web of Science, ProQuest, CINAHL, CNKI and Wanfang. Qualitative methods were used to generate codes and themes relating to the studies' context, mechanisms and outcomes. We checked chains of inference (connections) across extracted data and themes through an iterative process.

RESULTS

A total of 6345 articles were identified, and 52 articles were retained for final synthesis. The refined theoretical framework presents five areas of peer support, including informational support, instrumental support, emotional support, affiliational support and appraisal support; five types of outcomes that peer support can improve for PLHIV, including physiological outcomes, psychological outcomes, behavioural outcomes, cognitive outcomes and social outcomes; the effectiveness mechanism coding system from peer volunteers and the relationship between peer volunteers and PLHIV; and the sustainability mechanism coding system in terms of peer volunteers, PLHIV and study context.

CONCLUSIONS

Given that peer support has huge potential human resources, that is, all the qualified PLHIV, irreplaceable advantages in dealing with barriers to HIV-related discrimination and potential comprehensive benefits for PLHIV, it is necessary to develop and organise more peer support projects for PLHIV. Our study highlights that the expansion of peer support projects should be based on their effectiveness and sustainability.

A process and impact evaluation of a peer-led HIV self-management program

There is evidence that people with HIV (PWH) receive health-related benefits from having peer support and learning self-management skills. This evaluation assessed the effect of The Positive Life Workshop (TPLW)-a 7-session peer-led HIV self-management program-on psychosocial and HIV treatment outcomes. The overall sample included 1360 PWH who completed TPLW during 3/2015-2/2019. Surveys were administered before and after the program, and three months following program completion. Analyses examined changes in outcomes from pre-test to both post-test and 3-month follow-up using non-parametric tests. Subgroup analyses were conducted for 406 participants with ≥ 1 characteristic of the priority population for TPLW (i.e., recent HIV diagnosis, not taking antiretroviral therapy (ART), suboptimal ART adherence, unsuppressed viral load). In the overall sample, there were statistically significant improvements in HIV-related knowledge, social support, patient self-advocacy, and confidence in self-management between pre-test and post-test/3-month follow-up assessment. Analyses for the priority population showed significant increases from pre-test to 3-month follow-up in the proportion of participants who were ≥ 90 % adherent to ART (59-83 %, p < 0.01) and virally suppressed (42 % to 66 %, p < 0.01). The findings suggest the importance of ensuring HIV self-management interventions reach vulnerable populations of PWH who struggle with initiating and maintaining HIV-related health-promoting behaviors.

Help Is Available: Supporting Mental Wellness Through Peer Health Navigation with Young Black Men Who Have Sex with Men with HIV

Young black men who have sex with men (YBMSM) with HIV experience disproportionate rates of trauma, incarceration, poverty, racial discrimination, and homophobia. The synergistic effects of these adverse experiences, along with increased rates of mental health disorders, increase their risk for poor health. To address this need, the study authors adapted a current HIV service model to include a peer-health navigation intervention (WITH U) to attend to behavioral health, health literacy, linkage to services, and psychosocial support for YBMSM with HIV. This longitudinal, mixed-methods, nonexperimental study reports on the mental health burden among participants and the association between participation in WITH U and mental wellness outcomes. Participants (N = 65) were an average age of 25-26 years (mean = 25.48, standard deviation = 2.51). Over 25% of participants reported clinically significant depression and/or anxiety symptoms and nearly half the participants reported experiencing post-traumatic stress symptoms that were at least moderately difficult to handle. Quantitative analyses indicated no significant positive association between intervention engagement and mental health symptoms; however, reporting a greater number of depression symptoms was associated with attending fewer intervention sessions. Qualitative data analysis revealed that participants' mental wellness was positively impacted by participating in the intervention and that participants preferred to receive mental wellness support from peer health navigators (HNs) rather than licensed mental health professionals. Yet, peer HNs did not feel adequately prepared to address participants' mental wellness concerns. Increased training for peer HNs and development of a linkage process to more formalized mental health services with community input may strengthen mental wellness support.

What is the volume, diversity and nature of recent, robust evidence for the use of peer support in health and social care? An evidence and gap map

Background

Peer support interventions involve people drawing on shared personal experience to help one another improve their physical or mental health, or reduce social isolation. If effective, they may also lessen the demand on health and social care services, reducing costs. However, the design and delivery of peer support varies greatly, from the targeted problem or need, the setting and mode of delivery, to the number and content of sessions. Robust evidence is essential for policymakers commissioning peer support and practitioners delivering services in health care and community settings. This map draws together evidence on different types of peer support to support the design and delivery of interventions.

Objectives

The aim of this map was to provide an overview of the volume, diversity and nature of recent, high quality evidence on the effectiveness and cost-effectiveness of the use of peer support in health and social care.

Search Methods

We searched MEDLINE, seven further bibliographic databases, and Epistemonikos for systematic reviews (in October 2020), randomised controlled trials (in March 2021) and economic evaluations (in May 2021) on the effectiveness of peer support interventions in health and social care. We also conducted searches of Google Scholar, two trial registers, PROSPERO, and completed citation chasing on included studies.

Selection Criteria

Systematic reviews, randomised controlled trials and economic evaluations were included in the map. Included studies focused on adult populations with a defined health or social care need, were conducted in high-income countries, and published since 2015. Any measure of effectiveness was included, as was any form of peer support providing the peer had shared experience with the participant and a formalised role.

Data Collection and Analysis

Data were extracted on the type of peer support intervention and outcomes assessed in included studies. Standardised tools were used to assess study quality for all studies: assessing the methodological quality of systematic reviews 2 for systematic reviews; Cochrane risk of bias tool for randomised controlled trials; and consensus health economic criteria list for economic evaluations.

Main Results

We included 91 studies: 32 systematic reviews; 52 randomised controlled trials; and 7 economic evaluations. Whilst most included systematic reviews and economic evaluations were assessed to be of low or medium quality, the majority of randomised controlled trials were of higher quality. There were concentrations of evidence relating to different types of peer support, including education, psychological support, self-care/self-management and social support. Populations with long-term health conditions were most commonly studied. The majority of studies measured health-related indicators as outcomes; few studies assessed cost-effectiveness. Studies were unevenly distributed geographically, with most being conducted in the USA. Several gaps were evident regarding the delivery of peer support, particularly the integration of peers and professionals in delivering support and interventions of longer duration.

Authors' Conclusions

Although there is evidence available to inform the commissioning and delivery of peer support in health and social care, there are also clear gaps that need to be addressed to further support provision, particularly regarding cost-effectiveness. The effectiveness of peer support in different countries, with varying health and social care systems, is a priority for future research, as is the integration of peers with professionals in delivering peer support.

Effectiveness of a "Suppression Bundle" to improve HIV virologic suppression in an outpatient infectious disease clinic: a pilot implementation study

Despite effectiveness and accessibility of combined anti-retroviral therapy (cART), only 85% of people living with HIV (PLHIV) in the United States are virologically suppressed. Improving suppression is complex. Our objective was to consider unique factors in PLHIV with non-suppressed viral loads in clinic and improve the percentage of suppressed patients by implementing a "Suppression Bundle" consisting of three to five bundled interventions with the goal of improved suppression. Prior to the study, there were 567 HIV-positive patients receiving care in clinic. Of those, 89 had a measurable viral load (>40 copies/mL). In this pilot pre-post implementation, we focused on the 89 non-suppressed patients to (1) determine feasibility of implementing bundles and (2) increase the number of patients with suppressed viral loads pre- to post-intervention. Of non-suppressed patients, 65 were active in care immediately pre-intervention and participated in the pilot. At the completion of the 9-month intervention, 46 had viral loads <40 copies/mL, demonstrating substantial improvement with 70.1% of the previously non-suppressed patients achieving suppression. By considering unique patient factors, an individualized Suppression Bundle is acceptable, feasible, and may increase virally suppressed patients in an outpatient clinic. Next steps include determining whether suppression bundles can be implemented in differing practices.

Peer navigation for smoking cessation in smokers with HIV: Protocol for a randomized clinical trial

BACKGROUND

Smoking prevalence in persons with HIV (PWH) is high (40%) and cessation rates remain low. Lack of social support and poor adherence to nicotine replacement therapy (NRT) are related to poor cessation outcomes; thus, both factors represent possible targets for smoking cessation interventions. Peer navigators (PNs) have been integrated into HIV care with great success to improve engagement and adherence to antiretroviral therapy. However, no clinical trial has evaluated the potential for PNs to provide social support and improve NRT adherence for smoking cessation. We developed a treatment protocol that targets social support, adherence, and self-efficacy for quitting by incorporating PNs into a smoking cessation program. This randomized trial will test whether this approach results in higher rates of 7-day point prevalence abstinence at 12- and 24-weeks, compared to standard treatment.

METHODS

Seventy-two smokers with HIV will be randomized to either Peer Navigation Social Support for smoking cessation (PNSS-S) or standard cessation counseling. All participants will meet with a nurse for a smoking cessation counseling session, which will include discussion of FDA-approved cessation pharmacotherapy. Participants assigned to PNSS-S will receive weekly phone calls from the PN for 12 weeks. The PN will address readiness to quit, using medication to quit, common barriers to cessation, high risk situations, slip management, and maintaining abstinence. Smoking cessation outcomes will be measured at 4, 12, and 24 weeks following the baseline appointment.

CONCLUSION

Results from this study will provide preliminary evidence of whether incorporating a peer navigator-based intervention into smoking cessation treatment can improve smoking cessation outcomes in PWH.

A Systematic Review of Nurse-Led Antiretroviral Medication Adherence Intervention Trials: How Nurses Have Advanced the Science

ABSTRACT

Antiretroviral therapy (ART) is essential to achieving viral suppression and improving health and clinical outcomes in persons living with HIV. Despite the effectiveness of ART and many promising evidence-based ART adherence interventions, viral suppression rates continue to be less than optimal. Nurses play pivotal roles in HIV care management, yet their role in the development and delivery of evidence-based adherence interventions has received little attention. Therefore, this review examined the contributions of nurses to ART adherence research and delivery. We found that nurse-led and nurse-facilitated interventions can be effective in fostering ART adherence in persons living with HIV. Considering the role nurses play in HIV care management and the effectiveness of interventions involving nurses, more nurse-led and nurse-facilitated interventions to address ART adherence are indicated. However, there is a need for further research to examine multilevel interventions and comparative cost and effectiveness of nurse-delivered ART interventions with other forms of delivery.

The effectiveness of peer-support for people living with HIV: A systematic review and meta-analysis

BACKGROUND

The practice of involving people living with HIV in the development and provision of healthcare has gained increasing traction. Peer-support for people living with HIV is assistance and encouragement by an individual considered equal, in taking an active role in self-management of their chronic health condition. The objective of this systematic review was to assess the effects of peer-support for people living with HIV.

METHODS

We conducted a systematic review in accordance with international guidelines. Following systematic searches of eight databases until May 2020, two reviewers performed independent screening of studies according to preset inclusion criteria. We conducted risk of bias assessments and meta-analyses of the available evidence in randomised controlled trials (RCTs). The certainty of the evidence for each primary outcome was evaluated with the Grading of Recommendations Assessment, Development, and Evaluation system.

RESULTS

After screening 219 full texts we included 20 RCTs comprising 7605 participants at baseline from nine different countries. The studies generally had low risk of bias. Main outcomes with high certainty of evidence showed modest, but superior retention in care (Risk Ratio [RR] 1.07; Confidence Interval [CI] 95% 1.02-1.12 at 12 months follow-up), antiretroviral therapy (ART) adherence (RR 1.06; CI 95% 1.01-1.10 at 3 months follow-up), and viral suppression (Odds Ratio up to 6.24; CI 95% 1.28-30.5 at 6 months follow-up) for peer-support participants. The results showed that the current state of evidence for most other main outcomes (ART initiation, CD4 cell count, quality of life, mental health) was promising, but too uncertain for firm conclusions.

CONCLUSIONS

Overall, peer-support with routine medical care is superior to routine clinic follow-up in improving outcomes for people living with HIV. It is a feasible and effective approach for linking and retaining people living with HIV to HIV care, which can help shoulder existing services.

Agents of change: Comparing HIV-related risk behavior of people attending ART clinics in Dar es Salaam with members of their social networks

The aim of the study is to compare sociodemographic characteristics, psychosocial factors, HIV knowledge and risk behaviors of people living with HIV (PLH) and their social network members (NMs) to inform HIV prevention programs that engage PLH as prevention educators in their communities. We compared baseline characteristics of PLH enrolled in an intervention to become HIV prevention Change Agents (CAs) (n = 458) and 602 NMs they recruited. CAs and NMs responded to questionnaires through a computer-driven interface with Audio Computer-Assisted Self Interview (ACASI) software. Although NMs scored higher on socio-economic status, self-esteem and general self-efficacy, they had lower HIV knowledge (AOR 1.5; 95% CI: 1.1–2.1), greater inconsistent condom use (AOR 3.2; 95% CI: 2.4–4.9), and recent experience as perpetrators of physical (AOR 2.5; 95% CI: 1.2–5.1) or sexual (AOR 4.1; 95% CI: 1.4–12.7) intimate partner violence; and as victims of physical (AOR 1.5; 95% CI: 1.0–2.3) or sexual (AOR 2.2; 95% CI: 1.3–3.8) forms of violence than CAs. Higher HIV knowledge and lower sexual risk behaviors among CAs suggest PLH’s potential as communicators of HIV prevention information to NMs. CAs’ training should also focus on improving self-esteem, general self-efficacy and social support to increase their potential effectiveness as HIV prevention educators and enhance their own overall health and well-being.

Do interventions to improve adherence to antiretroviral therapy recognise diversity? A systematic review

People living with HIV (PLWH) are often culturally and linguistically diverse populations; these differences are associated with differing barriers to antiretroviral therapy (ART) adherence. Cultural competence measures the extent to which trial design recognises this diversity. This systematic review aimed to determine whether adherence trial participants represent the diversity of PLWH. Randomised Controlled Trials in Organisation for Economic Co-operation and Development countries to improve ART adherence were eligible. We searched MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews. For all included trials, we searched for their development, testing and evaluation studies. We compared trial participant characteristics with nationally reported PLWH data. We appraised trial cultural competence against ten criteria; scoring each criterion as 0, 1 or 2 indicating cultural blindness, pre-competence or competence respectively. For 80 included trials, a further 13 studies presenting development/testing/evaluation data for the included trials were identified. Only one of the 80 included studies reported trial participants representative of the country's population of PLWH. The median (IQ) cultural competence score was 2.5 (1.0, 4.0) out of 20. HIV adherence trial participants are not reflective of the population with HIV, which may be due to limited adoption of culturally competent research methods.

Peers Keep It Real: Re-engaging Adults in HIV Care

Background:

After diagnosis, a substantial number of people with HIV disease fall out of care. Effective interventions are needed for this priority population.

Methods:

The “Peers Keep It Real” study aimed to help adults who were disengaged from HIV treatment. Peers, lay individuals living with HIV, facilitated intervention sessions. Participants were randomized to immediately receive the peer-facilitated intervention or were wait-listed.

Results:

Considerable attrition occurred in the control group. Pre-/postanalyses showed that among participants (n = 23) who received the intervention, 65% had viral load suppression and 100% remained in care at 12 months postintervention. Impact on viral load was significant (P = .0326), suggesting that peers are effective change agents who positively impacted outcomes for individuals struggling with adherence to HIV treatment.

Conclusion:

Future endeavors should consider providing all individuals from this priority population with an active peer intervention from the onset to enhance retention and adherence.

Perceived Social Support Among Adults Struggling With Adherence to HIV Care and Treatment

Few studies have examined perceived social support among the subgroup of the HIV population that struggles with adherence to HIV care and treatment. A secondary analysis from 2 HIV medication adherence intervention studies was conducted using a mixed method design. Participants were not taking HIV medications as prescribed or had fallen out of HIV care. Two major themes emerged from the qualitative data analysis: extreme isolation and constant turmoil. Overall social support scores were low, as measured by the Medical Outcomes Study Social Support Survey. Convergent qualitative data excerpt corresponded with low scores on every dimension of the Medical Outcomes Study Social Support Survey. Findings from our study indicate that adults living with HIV who struggled with taking HIV medications lacked social support in many areas of their lives. Interventions that focus on perceptions of available social support may be helpful for individuals with ongoing HIV medication adherence challenges.

Peer-led Self-management Interventions and Adherence to Antiretroviral Therapy Among People Living with HIV: A Systematic Review

Adherence to antiretroviral therapy (ART) is essential to reduce morbidity and mortality among people living with HIV (PLWH). However, adherence remains suboptimal, and PLWH may benefit from more self-management support to address the complexities of chronic illness. Our objective was to identify the impact of peer-led self-management interventions on adherence and patient-reported outcomes (PROs) among PLWH. We searched MEDLINE, PubMed, Embase, PsycINFO, and CINAHL for English language publications from 1996 to March 2018, and included controlled intervention studies. Additional articles were handsearched, risk of bias assessed, and narrative syntheses outlined. Thirteen studies met inclusion criteria. Findings demonstrate unclear effectiveness for peer-led self-management interventions improving ART adherence; however evidence was limited with only seven studies measuring this outcome and some risk of bias. Many PROs were measured, with limited consistent findings. Future research is needed to strengthen the evidence regarding effects of peer-led self-management interventions on adherence and PROs among PLWH.

Alcohol Use and Ethnicity Independently Predict Antiretroviral Therapy Nonadherence Among Patients Living with HIV/HCV Coinfection

BACKGROUND

Adherence to antiretroviral therapy (ART) is important to counter synergistic effects of HIV and hepatitis C (HCV) in patients living with coinfection. Predictors of ART nonadherence among patients living with HIV/HCV coinfection are not well established. This knowledge would be advantageous for clinicians and behavioral health specialists who provide care to patients living with HIV/HCV coinfection.

OBJECTIVES

The purpose of this study was to assess prevalence and predictors of ART nonadherence in a sample of patients living with HIV/HCV coinfection who were actively in HIV clinical care.

METHOD

A sample of patients living with HIV/HCV coinfection who received care at a university-affiliated HIV clinic (n = 137) between January 2013 and July 2017 were included in the study. Computerized patient-reported data or outcomes (PROs) and electronic medical record data of these respective patients were collected and analyzed. Binomial logistic regression was used to examine predictors of ART nonadherence.

RESULTS

The prevalence of ART nonadherence was 31%. In multivariate analysis, African American ethnicity (OR = 3.28, CI 1.241-8.653, p = 0.017) and a higher number of alcoholic drinks per drinking day (OR = 1.31, CI 1.054-1.639, p = 0.015) were positively associated with ART nonadherence.

CONCLUSIONS

Behavioral health providers are encouraged to incorporate alcohol use reduce interventions in HIV clinical settings to reduce ART nonadherence among patients living with HIV/HCV coinfection. Additionally, public health professionals and researchers, and clinicians are encouraged to use inductive methods to discover why ART nonadherence disproportionately impacts African American patients living with HIV/HCV coinfection and to develop approaches that are sensitive to those respective barriers.

Community Inclusion in PrEP Demonstration Projects: Lessons for Scaling Up

Pre-exposure prophylaxis (PrEP) has emerged as a new HIV prevention strategy. A series of demonstration projects were conducted to explore the use of PrEP outside of clinical trial settings. Learning from the failures in community consultation and involvement in early oral tenofovir trials, these PrEP projects worked to better engage communities and create spaces for community involvement in the planning and roll out of these projects. We describe the community engagement strategies employed by seven Bill & Melinda Gates Foundation-funded PrEP demonstration projects. Community engagement has emerged as a critical factor for education, demand generation, dispelling rumors, and supporting adherence and follow up in the PrEP demonstration project case studies. The increasing global interest in PrEP necessitates understanding how to conduct community engagement for PrEP implementation in different settings as part of combination HIV prevention.

Assessing treatment outcomes among peer educators living with HIV in Kenya

BACKGROUND

People living with HIV (PLHIV) often face barriers in accessing quality and comprehensive HIV care, including stigma and discrimination, which results in poor retention and viral non-suppression. Peer-led interventions can help address these barriers. In Kenya, peer educators (PEs) are PLHIV who support other PLHIV to adhere to clinic schedules and antiretroviral medication uptake. In spite of their status as role models and their key role in supporting clients receiving HIV care and treatment, little is known about the characteristics and treatment outcomes of PEs themselves, specifically viral suppression.

METHODS

This is a retrospective descriptive analysis of program data on treatment outcomes of PEs engaged in active patient support activities between October 2010 and January 2017. All eligible PEs from 140 health facilities located in 23 counties of Kenya were included in the study. Data from 230 PEs were abstracted from the electronic medical records, patient files, and registers between June and August 2017. Study variables included key sociodemographic characteristics (sex, marital status, and age), duration on antiretroviral therapy (ART), WHO clinical staging, baseline CD4 count, current antiretroviral regimen and uptake of isoniazid preventive therapy (IPT). The outcome variable was viral suppression, defined as a viral load <1000 copies/ml.

RESULTS

Overall, 173/230 (75%) of the PEs were female, 144/230 (63%) were married, and median age (LQ, UQ) was 38.5 (33.0, 42.0) years. The PEs had been on ART for a median (LQ, UQ) duration of 76.0 (37.0, 105.0) months. Six months IPT completion was high at 97%. Of the 222 (97%) PEs with an up-to-date viral load taken within the last one year, 211 (95%) were virally suppressed.

CONCLUSION

Our study showed that peer educators actively engaged in patient support activities have achieved high viral suppression rates.

Adherence Connection for Counseling, Education, and Support: Research Protocol for a Proof-of-Concept Study

Background

The highest rates of new HIV infections are observed in African Americans and Hispanics/Latinos (ethnic minority) adolescents and young adults (youth). HIV-infected ethnic minority youth are less likely to initiate and maintain adherence to antiretroviral treatment (ART) and medical care, as compared with their adult counterparts.

Objective

The objective of this research protocol was to describe our proposed methods for testing a peer-led mobile health cognitive behavioral intervention, delivered via remote videoconferencing and smartphones with HIV-infected ethnic minority youth, Adherence Connection for Counseling, Education, and Support (ACCESS). Our secondary aim was to obtain initial estimates of the biobehavioral impact of ACCESS on HIV virologic outcomes and self-reported ART adherence, beliefs and knowledge about ART treatment, adherence self-efficacy, and health care utilization (retention in care).

Methods

An exploratory, sequential mixed-methods study design will be used with conceptual determinants of adherence behavior informed by the information-motivation-behavioral skills model. HIV-infected ethnic minority youth aged 16 to 29 years with a detectable HIV serum viral load of more than 200 copies/ml (N=25) will be recruited. Qualitative pretesting will be conducted, including semistructured, in-depth, individual interviews with a convenience sample meeting the study inclusion criteria. Preliminary analysis of qualitative data will be used to inform and tailor the ACCESS intervention. Testing and implementation will include a one-group pre-posttest pilot, delivered by a trained successful peer health coach who lives with HIV and is well-engaged in HIV care and taking ART. A total of 5 peer-led remote videoconferencing sessions will be delivered using study-funded smartphones and targeting adherence information (HIV knowledge), motivation (beliefs and perceptions), and behavioral skills (self-efficacy). Participant satisfaction will be assessed with poststudy focus groups and quantitative survey methodology. Bivariate analyses will be computed to compare pre- and postintervention changes in HIV biomarkers, self-reported ART adherence, beliefs and knowledge about ART, adherence self-efficacy, and retention in care.

Results

As of December 2018, we are in the data analysis phase of this pilot and anticipate completion with dissemination of final study findings by spring/summer 2019. The major outcomes will include intervention feasibility, acceptability, and preliminary evidence of impact on serum HIV RNA quantitative viral load (primary adherence outcome variable). Self-reported ART adherence and retention in care will be assessed as secondary outcomes. Findings from the qualitative pretesting will contribute to an improved understanding of adherence behavior.

Conclusions

Should the ACCESS intervention prove feasible and acceptable, this research protocol will contribute to a shift in existent HIV research paradigms by offering a blueprint for technology-enabled peer-led interventions and models.

Community health worker interventions to promote psychosocial outcomes among people living with HIV-A systematic review

Background

Community health worker (CHW) interventions are a successful strategy to promote health among HIV-negative and persons living with HIV (PLWH). Psychosocial factors are critical dimensions of HIV/AIDS care contributing to prognosis of the disease, yet it is unclear how CHW interventions improve psychosocial outcomes in PLWH. The purpose of this study was to critically appraise the types, scope, and nature of CHW interventions designed to address psychosocial outcomes in PLWH.

Methods

We performed database searches—PubMed, EMBASE, CINAHL, and Cochrane—to identify randomized controlled trials published in English before April 2017. Fourteen articles met the eligibility criteria.

Results

Half of the studies were conducted in the United States. Social cognitive theory was used more than once in nine theory-guided studies. CHW interventions were largely focused on reducing depression (n = 6) or stigma related to HIV (n = 4), or promoting quality of life (n = 4), social support (n = 4), and self-efficacy (n = 4). Didactic methods and role-playing were used to train CHWs. CHWs played multiple roles in delivering intervention, including a counselor and a supporter (n = 10), educator (n = 5), or a navigator (n = 3). CHW intervention fidelity was assessed in 4 studies. Five studies found positive changes in six psychosocial outcomes including quality of life (2 of 4) and self-efficacy (2 of 4). CHW interventions had no effect on social support in 2 of 4 studies, and stigma in 3 of 4 studies. None of the CHW interventions were successful in reducing depressive symptoms among PLWH.

Conclusions

Evidence partially supported the use of CHWs in promoting psychosocial outcomes in PLWH. Future CHW intervention should be expanded in scope to address key psychosocial determinants of HIV/AIDS outcomes such as health literacy. Further, fidelity measures should be incorporated into intervention delivery.

A systematic review of peer-supported interventions for health promotion and disease prevention

Prior research has examined peer programs with respect to specific peer roles (e.g.; peer support) or specific health/wellness domains (e.g.; exercise/diet), or have aggregated effects across roles and domains. We sought to conduct a systematic review that categorizes and assesses the effects of peer interventions to promote health and wellness by peer role, intervention type, and outcomes. We use evidence mapping to visually catalog and synthesize the existing research. We searched PubMed and WorldCat databases (2005 to 2015) and New York Academy of Medicine Grey Literature Report (1999 to 2016) for English-language randomized control trials. We extracted study design, study participants, type of intervention(s), peer role(s), outcomes assessed and measures used, and effects from 116 randomized controlled trials. Maps were created to provide a visual display of the evidence by intervention type, peer role, outcome type, and significant vs null or negative effects. There are more null than positive effects across peer interventions, with notable exceptions: group-based interventions that use peers as educators or group facilitators commonly improve knowledge, attitudes, beliefs, and perceptions; peer educators also commonly improved social health/connectedness and engagement. Dyadic peer support influenced behavior change and peer counseling shows promising effects on physical health outcomes. Programs seeking to use peers in public health campaigns can use evidence maps to identify interventions that have previously demonstrated beneficial effects. Those seeking to produce health outcomes may benefit from identifying the mechanisms by which they expect their program to produce these effects and associated proximal outcomes for future evaluations.

Although we attempted to register our protocol with PROSPERO, we did not meet eligibility criteria because we were past the data collection phase. The full PROSPERO-aligned protocol is available from the authors.

Challenges in the Evaluation of Interventions to Improve Engagement Along the HIV Care Continuum in the United States: A Systematic Review

In the United States (US), there are high levels of disengagement along the HIV care continuum. We sought to characterize the heterogeneity in research studies and interventions to improve care engagement among people living with diagnosed HIV infection. We performed a systematic literature search for interventions to improve HIV linkage to care, retention in care, reengagement in care and adherence to antiretroviral therapy (ART) in the US published from 2007-mid 2015. Study designs and outcomes were allowed to vary in included studies. We grouped interventions into categories, target populations, and whether results were significantly improved. We identified 152 studies, 7 (5%) linkage studies, 33 (22%) retention studies, 4 (3%) reengagement studies, and 117 (77%) adherence studies. 'Linkage' studies utilized 11 different outcome definitions, while 'retention' studies utilized 39, with very little consistency in effect measurements. The majority (59%) of studies reported significantly improved outcomes, but this proportion and corresponding effect sizes varied substantially across study categories. This review highlights a paucity of assessments of linkage and reengagement interventions; limited generalizability of results; and substantial heterogeneity in intervention types, outcome definitions, and effect measures. In order to make strides against the HIV epidemic in the US, care continuum research must be improved and benchmarked against an integrated, comprehensive framework.

Improving Engagement in the HIV Care Cascade: A Systematic Review of Interventions Involving People Living with HIV/AIDS as Peers

Improving patient engagement in HIV care is critical for maximizing the impact of antiretroviral therapy (ART). We conducted a systematic review of studies that used HIV-positive peers to bolster linkage, retention, and/or adherence to ART. We searched articles published and indexed in Pubmed, PsycINFO, and CINAHL between 1996 and 2014. Peers were required to be HIV-positive. Studies were restricted to those published in English. Nine studies with n = 4658 participants met the inclusion criteria. Peer-based interventions were predominantly focused on improving adherence to ART, or evaluations of retention and adherence via viral suppression. Five (56 %) were conducted in sub-Saharan Africa. Overall findings were mixed on the impact of peers on ART adherence, viral suppression, and mortality. While positive effects of peer interventions on improving linkage and retention were found, there were limited studies assessing these outcomes. Additional research is warranted to demonstrate the impact of peers on linkage and retention in diverse populations.
