Strategic roles for health communication in combination HIV prevention and care programs

Patient-Provider Health Communication Strategies: Enhancing HPV Vaccine Uptake among Adolescents of Color

Cervical cancer remains a public health issue in the United States, particularly among stigmatized racial and ethnic populations. The human papillomavirus (HPV) vaccine has been clinically proven to prevent cervical cancers, and other HPV-associated cancers, among men and women. However, HPV vaccine uptake is suboptimal; only 55% of adolescents complete the two-dose series by age 15. Past research has shown that provider HPV vaccine communication for people of marginalized races/ethnicities is subpar. This article focuses on provider communication strategies to promote HPV vaccine uptake effectively and equitably. The authors reviewed the literature on evidence-based patient-provider HPV vaccine communication techniques to create a set of communication language providers could use and avoid using to enhance HPV vaccine acceptance and uptake among adolescents of marginalized racial and ethnic groups. Evidence has shown that information and the manner of dissemination are critical for influencing HPV vaccine uptake. These communication strategies must be suited to the context of the targeted population, and the message content can be broadly categorized into source, content, and modality. Strategies to improve patient-provider communication among adolescents of color using source, modality, and content include the following: (1) Source: increase provider self-efficacy to provide the recommendation, building rapport between providers and parents; (2) Content: persistent, forceful language with minimal acquiescence should be employed, reframing the conversation focus from sex to cancer; and (3) Modality: use multiple vaccine reminder modalities, and work with the community to culturally adapt the vaccination language. Utilizing effective behavior-change communication adapted for adolescents of color can reduce missed opportunities for HPV prevention, potentially decreasing racial and ethnic disparities in HPV-related morbidity and mortality.

Evidence and gap map report: Social and Behavior Change Communication (SBCC) interventions for strengthening HIV prevention and research among adolescent girls and young women (AGYW) in low- and middle-income countries (LMICs)

BACKGROUND

Adolescent girls and young women (AGYW), aged 15-24 years, are disproportionately affected by HIV and other sexual and reproductive health (SRH) risks due to varying social, cultural, and economic factors that affect their choices and shape their knowledge, understanding, and practices with regard to their health. Socio-Behavioral Change Communication (SBCC) interventions targeted at strengthening the capabilities of individuals and their networks have supported the demand and uptake of prevention services and participation in biomedical research. However, despite growing global recognition of the domain, high-quality evidence on the effectiveness of SBCC remains scattered. This evidence and gap map (EGM) report characterizes the evidence base on SBCC interventions for strengthening HIV Prevention and Research among AGYW in low- and middle-income countries (LMICs), identifying evidence gaps and outlining the scope of future research and program design.

OBJECTIVES

The objectives of the proposed EGM are to: (a) identify and map existing EGMs in the use of diverse SBCC strategies to strengthen the adoption of HIV prevention measures and participation in research among AGYW in LMICs and (b) identify areas where more interventions and evidence are needed to inform the design of future SBCC strategies and programs for AGYW engagement in HIV prevention and research.

METHODS

This EGM is based on a comprehensive search of systematic reviews and impact evaluations corresponding to a range of interventions and outcomes-aimed at engaging AGYW in HIV prevention and research - that were published in LMICs from January 2000 to April 2021. Based on guidance for producing a Campbell Collaboration EGM, the intervention and outcome framework was designed in consultation with a group of experts. These interventions were categorized across four broad intervention themes: mass-media, community-based, interpersonal, and Information Communication and Technology (ICT)/Digital Media-based interventions. They were further sub-categorized into 15 intervention categories. Included studies looked at 23 unique behavioral and health outcomes such as knowledge attitude and skills, relationship dynamics, household dynamics, health care services, and health outcomes and research engagement. The EGM is presented as a matrix in which the rows are intervention categories/sub-categories, and the columns are outcome domains/subdomains. Each cell is mapped to an intervention targeted at outcomes. Additional filters like region, country, study design, age group, funding agency, influencers, population group, publication status, study confidence, setting, and year of publication have been added.

SELECTION CRITERIA

To be eligible, studies must have tested the effectiveness of SBCC interventions at engaging AGYW in LMICs in HIV prevention and research. The study sample must have consisted of AGYW between the ages of 15-24, as defined by UNAIDS. Both experimental (random assignment) and quasi-experimental studies that included a comparison group were eligible. Relevant outcomes included those at the individual, influencer, and institutional levels, along with those targeting research engagement and prevention-related outcomes.

RESULTS

This EGM comprises 415 impact evaluations and 43 systematic reviews. Interventions like peer-led interactions, counseling, and community dialogues were the most dominant intervention sub-types. Despite increased digital penetration use of media and technology-driven interventions are relatively less studied. Most of the interventions were delivered by peers, health care providers, and educators, largely in school-based settings, and in many cases are part of sex-education curricula. Evidence across geographies was mostly concentrated in Sub-Saharan Africa (70%). Most measured outcomes focused on disease-related knowledge dissemination and enhancing awareness of available prevention options/strategies. These included messaging around consistent condom use, limiting sexual partners, routine testing, and awareness. Very few studies were able to include psychographic, social, and contextual factors influencing AGYW health behaviors and decisions, especially those measuring the impact of social and gender norms, relationship dynamics, and household dynamics-related outcomes. Outcomes related to engagement in the research were least studied.

CONCLUSION

This EGM highlights that evidence is heavily concentrated within the awareness-intent spectrum of behavior change and gets lean for outcomes situated within the intent-action and the action-habit formation spectrum of the behavior change continuum. Most of the evidence was concentrated on increasing awareness, knowledge, and building risk perception around SRH domains, however, fewer studies focused on strengthening the agency and self-efficacy of individuals. Similarly, evidence on extrinsic factors-such as strengthening social and community norms, relationships, and household dynamics-that determine individual thought and action such as negotiation and life skills were also found to be less populated. Few studies explore the effectiveness of these interventions across diverse AGYW identities, like pregnant women and new mothers, sex workers, and people living with HIV, leading to limited understanding of the use of these interventions across multiple user segments including key influencers such as young men, partners, families, religious leaders, and community elders was relatively low. There is a need for better quality evidence that accounts for the diversity of experiences within these populations to understand what interventions work, for whom, and toward what outcome. Further, the evidence for use of digital and mass-media tools remains poorly populated. Given the increasing penetration of these tools and growing media literacy on one end, with widening gender-based gaps on the other, it is imperative to gather more high-quality evidence on their effectiveness. Timely evidence generation can help leverage these platforms appropriately and enable intervention designs that are responsive to changing communication ecologies of AGYW. SBCC can play a critical role in helping researchers meaningfully engage and collaborate with communities as equal stakeholders, however, this remains poorly evidenced and calls for investigation and investment.

PROTOCOL: Social and behaviour change communication interventions for strengthening HIV prevention and research among adolescent girls and young women in low- and middle-income countries: An evidence and gap map

Despite progress in several dimensions of the global HIV response, there seems to be a significant gender and age disparity. Numerous organizations consider it a top priority to accelerate HIV prevention programming among Adolescent Girls and Young Women (AGYW) as unequal gender norms, limited agency and voice, and reduced access to resources put them at higher HIV risk. Gender and age have also been identified as critical gaps within prevention research to ensure the development of biomedical interventions that are responsive to the biological and social needs of AGYW. Towards this, the objectives of the proposed evidence and gap map are to; identify and map existing evidence and gaps on the use of diverse Social and Behaviour Change Communication (SBCC) strategies to strengthen adoption of HIV prevention measures and participation in research among AGYW in LMICs; and, identify areas where more interventions and evidence are needed to inform the design of future SBCC strategies and programs for AGYW engagement in HIV prevention and research.

Learning from combination HIV prevention programmes to face COVID-19 emerging pandemic

Before a vaccine against SARS-CoV-2 became available, several measures to control COVID-19 pandemic are necessary. Analogously, in the absence of an available vaccine, Combination HIV Prevention Programmes have consolidated a large experience of biomedical, behavioral and structural interventions suitable for several epidemiological settings. Adaptation of such experiences can organize mid-term and long-term responses to face COVID-19.

Social representations of mother-to-child transmission of HIV and its prevention in narratives by young Africans from five countries, 1997-2014: Implications for communication

International recommendations related to the prevention of mother-to-child transmission (PMTCT) of HIV have evolved rapidly over time; recommendations have also varied contextually in line with local constraints and national policies. This study examines how young Africans made sense of mother-to-child transmission (MTCT) and PMTCT and related barriers and facilitators between 1997 and 2014 in the context of these complex and changing recommendations. It uses a distinctive data source: 1343 creative narratives submitted to HIV-themed scriptwriting competitions by young people aged 10-24 from 5 African countries (Senegal, Burkina Faso, Nigeria, Kenya, and Swaziland) between 1997 and 2014. The study triangulates between analysis of quantifiable characteristics of the narratives, thematic qualitative analysis, and narrative-based approaches. MTCT occurs in 8% of the narratives (108), while it is prevented in 5% (65). Narratives differ according to whether they depict MTCT or PMTCT (or, rarely, both), evolve over time, and show cross-national thematic variation. In the aggregate, representations shift in line with increased access to testing and antiretroviral medications, with PMTCT narratives becoming more frequent and MTCT narratives becoming more hopeful as diagnosis becomes the gateway to ART access. However, storylines of intergenerational tragedy in which MTCT is depicted as inevitable persist through 2014. Alongside cross-national differences in theme and tone, narratives from higher prevalence Swaziland and Kenya situate MTCT/PMTCT more centrally within descriptions of life with HIV. Findings illustrate the need to improve communication about PMTCT, reframing negative cultural narratives to reflect the full promise of developments of the past decade and a half.

Feasibility and Acceptability of Health Communication Interventions Within a Combination Intervention Strategy for Improving Linkage and Retention in HIV Care in Mozambique

BACKGROUND

Challenges to ensuring timely linkage to and retention in HIV care are well documented. Combination intervention strategies can be effective in improving the HIV care continuum. Data on feasibility and acceptability of intervention types within intervention packages are limited.

METHODS

The Engage4Health study assessed the effectiveness of a combination intervention strategy to increase linkage and retention among adults newly diagnosed with HIV in Mozambique. The study included 2 health communication interventions-modified delivery of pre-antiretroviral therapy (pre-ART) counseling sessions and SMS reminders-and 3 structural interventions-point-of-care CD4 testing after diagnosis, accelerated ART initiation, and noncash financial incentives. We used a process evaluation framework to assess dose delivered-extent each intervention was delivered as planned-and dose received-participant acceptability-of health communication versus structural interventions in the effectiveness study to understand associated benefits and challenges. Data sources included study records, participant interviews, and clinical data.

RESULTS

For dose delivered of health communication interventions, 98% of eligible clients received pre-ART counseling and 90% of participants received at least one SMS reminder. For structural interventions, 74% of clients received CD4 testing and 53% of eligible participants initiated ART within 1 month. Challenges for structural interventions included facility-level barriers, staffing limitations, and machine malfunctions. For dose received, participants reported pre-ART counseling and CD4 testing as the most useful interventions for linkage and financial incentives as the least useful for linkage and retention.

DISCUSSION

Findings demonstrate that health communication interventions can be feasibly and acceptably integrated with structural interventions to create combination intervention strategies.

Effective Interpersonal Health Communication for Linkage to Care After HIV Diagnosis in South Africa

Background:

Early in the global response to HIV, health communication was focused toward HIV prevention. More recently, the role of health communication along the entire HIV care continuum has been highlighted. We sought to describe how a strategy of interpersonal communication allows for precision health communication to influence behavior regarding care engagement.

Methods:

We analyzed 1 to 5 transcripts from clients participating in longitudinal counseling sessions from a communication strategy arm of a randomized trial to accelerate entry into care in South Africa. The counseling arm was selected because it increased verified entry into care by 40% compared with the standard of care. We used thematic analysis to identify key aspects of communication directed specifically toward a client's goals or concerns.

Results:

Of the participants, 18 of 28 were female and 21 entered HIV care within 90 days of diagnosis. Initiating a communication around client-perceived consequences of HIV was at times effective. However, counselors also probed around general topics of life disruption—such as potential for child bearing—as a technique to direct the conversation toward the participant's needs. Once individual concerns and needs were identified, counselors tried to introduce clinical care seeking and collaboratively discuss potential barriers and approaches to overcome to accessing that care.

Conclusions:

Through the use of interpersonal communication messages were focused on immediate needs and concerns of the client. When effectively delivered, it may be an important communication approach to improve care engagement.

Health Communication and the HIV Continuum of Care

Health communication is a broad term that applies to the fundamental need for practitioners, policy makers, patients, and community members to understand one another around health promotion and health care issues. Whether in a consultation between nurse and patient, a health clinic director's engagement with the health ministry, or a community campaign for encouraging HIV testing, all have critical health communication elements. When people's needs are not perceived by them to be addressed or clients/patients do not understand what is being communicated, they are unmotivated to engage. Health communication may be deployed at multiple levels to encourage positive behavior change and affect HIV treatment outcomes. As countries move to treatment for all as soon as possible after testing, health communication can help address significant losses at each stage of the HIV continuum of care, thereby contributing to achieving the 90-90-90 global treatment goals. This JAIDS supplement presents compelling studies that are anchored on the health communication exigencies in highly diverse HIV and AIDS contexts in low and middle income settings. Our special focus is health communication needs and challenges within the HIV continuum of care. We introduce the supplement with thumbnails summaries of the work presented by an experienced array of public health, behavioral, and clinical scientists.

A Framework for Health Communication Across the HIV Treatment Continuum

Supplemental Digital Content is Available in the Text.

Background:

As test and treat rolls out, effective interventions are needed to address the determinants of outcomes across the HIV treatment continuum and ensure that people infected with HIV are promptly tested, initiate treatment early, adhere to treatment, and are virally suppressed. Communication approaches offer viable options for promoting relevant behaviors across the continuum.

Conceptual Framework:

This article introduces a conceptual framework, which can guide the development of effective health communication interventions and activities that aim to impact behaviors across the HIV treatment continuum in low- and medium-income countries. The framework includes HIV testing and counseling, linkage to care, retention in pre-antiretroviral therapy and antiretroviral therapy initiation in one single-stage linkage to care and treatment, and adherence for viral suppression. The determinants of behaviors vary across the continuum and include both facilitators and barriers with communication interventions designed to focus on specific determinants presented in the model. At each stage, relevant determinants occur at the various levels of the social–ecological model: intrapersonal, interpersonal, health services, community, and policy. Effective health communication interventions have mainly relied on mHealth, interpersonal communication through service providers and peers, community support groups, and treatment supporters.

Discussion:

The conceptual framework and evidence presented highlight areas across the continuum where health communication can significantly impact treatment outcomes to reach the 90-90-90 goals by strategically addressing key behavioral determinants. As test and treat rolls out, multifaceted health communication approaches will be critical.

Expanded antiretroviral treatment, sexual networks, and condom use: Treatment as prevention unlikely to succeed without partner reduction among men who have sex with men in China

Background

To project the impact of partner reduction on preventing new HIV infections among men who have sex with men (MSM) under varying conditions of enhanced HIV testing and treatment (T&T) and condom use in Beijing, China.

Methods and findings

A complex network model was fitted to predict the number of new HIV infections averted from 2014 to 2023 under four scenarios of sexual behavior risk reduction (S)—S1: Male sexual partners decrease (reduced by a random value m from 1–50) while condom use increases (risk constant p is a random value between 0.2 and 1]); S2: Both sexual partners and condom use decrease (m 1, 50; p 1, 1.8); S3: Sexual partners reduce (m 1, 10) while condom use increases or decreases (p 0.2, 1.8); S4: Only MSM with ≥100 male sexual partners reduce their partners (m 1, 50) while condom use increases (p 0.2, 1).

HIV prevalence will reach 23.2% by 2023 among Beijing MSM if T&T remains at the 2013 level. The three most influential factors are: T&T coverage; partner reduction (m); and the background risk (p). Under scenarios 1–4 of sexual behavioral changes with enhanced T&T interventions, the cumulative HIV new infections prevented over the 10 years will be 46.8% for S1 (interquartile range [IQR] 32.4%, 60.1%); 29.7% for S2 (IQR 18.0%, 41.4%), 23.2% for S3 (IQR 12.2%, 37.0%) and 11.6% for S4 (IQR 4.0%, 26.6%), respectively. The reproduction number R₀ could drop below 1 if there were a substantial reduction of male sexual partners and/or expanded condom use.

Conclusion

Partner reduction is a vital factor within HIV combination interventions to reduce HIV incidence among Beijing MSM, with substantial additional benefits derived from condom use. T&T without substantial partner reduction and increased condom use is less promising unless its implementation were extremely (and improbably) efficient.

Measuring Health Literacy Among Adults with HIV Infection in Mozambique: Development and Validation of the HIV Literacy Test

The role of health literacy on HIV outcomes has not been evaluated widely in Africa, in part because few appropriate literacy measures exist. We developed a 16-item scale, the HIV Literacy Test (HIV-LT) to assess literacy-related tasks needed to participate in HIV care. Items were scored as correct or incorrect; higher scores indicated higher literacy skill (range 0-100 %). We tested internal reliability (Kuder-Richardson coefficient) of the HIV-LT in a convenience sample of 319 Portuguese-speaking, HIV infected adults on antiretroviral treatment in Maputo, Mozambique. Construct validity was assessed by a hypothetical model developed a priori. The HIV-LT was reliable and valid to measure participants' literacy skills. The mean HIV-LT score was 42 %; literacy skills applicable to HIV care were challenging for many participants. The HIV-LT could be used to assess the relationship of literacy and HIV-related outcomes in diverse settings, and evaluate interventions to improve health communication for those in HIV care.

Monitoring and assessment of outcome in cases of tuberculosis in a municipality of Southern Brazil

Objectives To monitor and assess the outcome of treatment for pulmonary tuberculosis in the tuberculosis control program in a prioritized municipality in Southern Brazil. Methods a quantitative study, descriptive, documentary, using records of people with tuberculosis in treatment between 2009-2013, the collection took place between June and July 2014 in the Tuberculosis Control Program. Descriptive statistics was used. Results The average number of consultations among the 629 patients was 7.2 per patient, with a mean interval of 1.03 months between visits. The average of smears was 2.7 tests per patient during the study period. The outcome of treatment was a cure rate of 87.8%, an abandonment rate of 8.3% and 6.5% of deaths. Conclusions despite the cure rate, abandonment is still high, thus, it is necessary to explore strategies for better adherence to treatment, and the commitment of the municipal administration in articulating monitoring in primary health care.

Pre-exposure prophylaxis for sexually-acquired HIV risk management: a review

Despite significant efforts, the rate of new HIV infections worldwide remains unacceptably high, highlighting the need for new HIV prevention strategies. HIV pre-exposure prophylaxis (PrEP) is a new approach that involves the ongoing use of antiretroviral medications by HIV-negative individuals to reduce the risk of HIV infection. The use of daily tenofovir/emtricitabine as oral PrEP was found to be effective in multiple placebo-controlled clinical trials and approved by the United States Food and Drug Administration. In addition, the Centers for Disease Control and Prevention in the United States and the World Health Organization have both released guidelines recommending the offer of oral PrEP to high-risk populations. The scale-up of PrEP is underway, but several implementation questions remain unanswered. Demonstration projects and open-label extensions of placebo-controlled trials are ongoing and hope to contribute to our understanding of PrEP use and delivery outside the randomized controlled trial setting. Evidence is beginning to emerge from these open-label studies and will be critical for guiding PrEP scale-up. Outside of such studies, PrEP uptake has been slow and several client- and provider-related barriers are limiting uptake. Maximizing the public health impact of PrEP will require rollout to be combined with interventions to promote uptake, support adherence, and prevent increases in risk behavior. Additional PrEP strategies are currently under investigation in placebo-controlled clinical trials and may be available in the future.
