A mega-aggregation framework synthesis of the barriers and facilitators to linkage, adherence to ART and retention in care among people living with HIV

Factors Influencing Weight Management in Pregnant Women with Overweight or Obesity: A Meta-Synthesis of Qualitative Studies

BACKGROUND

Overweight and obesity have multiple negative consequences for the health of both the mother and the child. Interventions to prevent excessive weight gain during pregnancy have had varying success, and the proportion of pregnant women who exceed national guidelines for weight gain continues to increase.

OBJECTIVE

To investigate the influence of factors on weight management among pregnant women with overweight or obesity.

METHODS

This meta-synthesis of qualitative studies involved searching databases PubMed, Embase, Cochrane, Scopus, and Web of Science. The databases were searched on October 4, 2022, and the search was updated on April 21, 2023. The screening of titles, abstracts, and full texts was conducted utilizing Covidence software. The quality assessment of the articles was performed using the Critical Appraisal Skills Programme checklist. The Enhancing Transparency in Reporting the Synthesis of Qualitative Research statement was used to enhance transparency in reporting. A meta-aggregation approach was used to guide the data extraction and synthesis.

RESULTS

A total of 46 studies with appropriate Critical Appraisal Skills Programme scores were included for qualitative synthesis. Findings were extracted and integrated into 4 themes: psychological factors (personally driven negative emotions and society-driven negative emotions), social factors (societal attitudes and beliefs and social support resources), factors related to education and counseling (information provision and communication), and factors associated with effective care (provided care components and the method of providing effective care).

CONCLUSIONS

To improve weight management during pregnancy, health care providers should provide tailored and individualized recommendations that take into consideration the factors influencing these women.

A qualitative assessment of retention in HIV care among adolescents and young adults (AYA) living with HIV in New York City

Retention in HIV care is a critical precursor to ending the epidemic yet remains suboptimal in the United States. Gaining an understanding of the challenges faced by adolescents and young adults (AYA) living with HIV is essential to improving retention in HIV care. This study explored the barriers and facilitators to retention in care among Black and Hispanic AYA living with HIV. Audio-recorded semi-structured interviews were conducted with 20 AYA living with HIV ages 16-29 years in New York City. Our methods entailed an inductive content analysis to explore key concepts, reconcile codes, and identify a theme, categories, and subcategories. Bronfenbrenner's socioecological model evolved as an organizing framework around barriers and facilitators to retention in care at the individual, interpersonal, healthcare system, and structural level. Data analysis yielded one overarching theme-the influence of psychosocial factors on retention in HIV care. Psychological struggles, powerlessness, clinic-level characteristics, and socioeconomic struggles were barriers reported by participants. Self-responsibility, social support, patient-friendly healthcare services, and socioeconomic resources emerged as facilitators. Retention in HIV care among AYA living with HIV is a multifaceted and complex phenomenon that involves multiple systems. Strengthening patients, healthcare system, and community partnerships can help address some of the HIV-related health disparities.

Effectiveness of interventions designed to mitigate the negative health outcomes of informal caregiving to older adults: an umbrella review of systematic reviews and meta-analyses

OBJECTIVES

This umbrella review aimed to evaluate whether certain interventions can mitigate the negative health consequences of caregiving, which interventions are more effective than others depending on the circumstances, and how these interventions are experienced by caregivers themselves.

DESIGN

An umbrella review of systematic reviews was conducted.

DATA SOURCES

Quantitative (with or without meta-analyses), qualitative and mixed-methods systematic reviews were included.

ELIGIBILITY CRITERIA

Reviews were considered eligible if they met the following criteria: included primary studies targeting informal (ie, unpaid) caregivers of older people or persons presenting with ageing-related diseases; focused on support interventions and assessed their effectiveness (quantitative reviews) or their implementation and/or lived experience of the target population (qualitative reviews); included physical or mental health-related outcomes of informal caregivers.

DATA EXTRACTION AND SYNTHESIS

A total of 47 reviews were included, covering 619 distinct primary studies. Each potentially eligible review underwent critical appraisal and citation overlap assessment. Data were extracted independently by two reviewers and cross-checked. Quantitative review results were synthesised narratively and presented in tabular format, while qualitative findings were compiled using the mega-aggregation framework synthesis method.

RESULTS

The evidence regarding the effectiveness of interventions on physical and mental health outcomes was inconclusive. Quantitative reviews were highly discordant, whereas qualitative reviews only reported practical, emotional and relational benefits. Multicomponent and person-centred interventions seemed to yield highest effectiveness and acceptability. Heterogeneity among caregivers, care receivers and care contexts was often overlooked. Important issues related to the low quality of evidence and futile overproduction of similar reviews were identified.

CONCLUSIONS

Lack of robust evidence calls for better intervention research and evaluation practices. It may be warranted to avoid one-size-fits-all approaches to intervention design. Primary care and other existing resources should be leveraged to support interventions, possibly with increasing contributions from the non-profit sector.

Categorising implementation determinants and strategies within the US HIV implementation literature: a systematic review protocol

INTRODUCTION

Despite decreased rates of new infections, HIV/AIDS continues to impact certain US populations. In order to achieve the goals laid out in the Ending the HIV Epidemic (EHE) in the US initiative, implementation science is needed to expand the sustained use of effective prevention and treatment interventions, particularly among priority populations at risk for and living with HIV/AIDS. Over 200 HIV-related implementation studies have been funded by the US National Institutes of Health. Therefore, a comprehensive review of the literature identifying implementation determinants (barriers and facilitators) and categorising implementation strategies across the continuum of HIV prevention and care in the USA is appropriate and needed to enhance current knowledge and help achieve the goals laid out in the EHE national strategic plan.

METHODS AND ANALYSIS

This systematic review protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Between November 2020 and January 2022, a broad database search strategy of Ovid MEDLINE, PsycINFO and Web of Science was conducted to capture implementation-related studies along the HIV prevention and care continuum. Articles were eligible for inclusion if they were: conducted in the USA, published after the year 2000, written in English, related to HIV/AIDS, focused on outcomes related to dissemination and implementation (ie, did not test/evaluate/explore implementation determinants or strategies) and were behavioural studies (ie, not basic science). We plan to conduct three systematic reviews to identify and categorise determinants and strategies associated with three HIV focus areas: pre-exposure prophylaxis, testing/diagnosing and linkage to care, and treatment. Determinants will be coded according to an adapted Consolidated Framework for Implementation Research 2.0. Implementation strategies and outcomes will be categorised in accordance with existing taxonomies and frameworks.

ETHICS AND DISSEMINATION

Ethics approval is not applicable. No original data will be collected. Results will be disseminated through peer-reviewed publications, conference presentations and via online tools.

Types and associated methodologies of overviews of reviews in health care: a methodological study with published examples

OBJECTIVES

To provide a descriptive insight into the different types of research questions/objectives and associated methodologies of overviews of reviews, supplemented by representative examples from the health care literature.

STUDY DESIGN AND SETTING

We searched in methodological articles for information on types and methodologies used in overviews and we explored the typology of reviews to identify similar types in literature of overviews. We categorized the types of overviews based on the research question/objective and the methodological approach used. Indicative examples for each category were selected from a sample of 2,121 overviews that were retrieved between 2000 and 2022 from MEDLINE, Scopus, and Cochrane Database of Systematic Reviews.

RESULTS

Based on type of research question, overviews were classified as overviews of reviews of interventions, associations, prediction, diagnostic accuracy, prevalence/incidence, experiences/views, economic evaluation, and measurement properties. Based on the methodological approach, we identified a variety of methods (systematic, living, rapid, scoping, evidence mapping, framework, and methodological) used in overviews.

CONCLUSION

The proposed classification and examples provide an essential starting point for future theory-building research on typologies and study designs of overviews of reviews. It is important for methodologists to make vigorous effort to create consensus-based methodological and reporting guidelines to cover these diverse types and key methodological challenges.

Cannabis Use Is Associated With Decreased Antiretroviral Therapy Adherence Among Older Adults With HIV

Background

Conflicting evidence exists on the impact of cannabis use on antiretroviral therapy (ART) adherence among people with human immunodeficiency virus (PWH). We leveraged data collected among older PWH to characterize longitudinal associations between cannabis use and ART adherence.

Methods

AIDS Clinical Trials Group (ACTG) A5322 study participants were categorized as <100% (≥1 missed dose in past 7 days) or 100% (no missed doses) ART adherent. Participants self-reported current (past month), intermittent (past year but not past month), and no cannabis (in past year) use at each study visit. Generalized linear models using generalized estimating equations were fit and inverse probability weighting was used to adjust for time-varying confounders and loss to follow-up.

Results

Among 1011 participants (median age, 51 years), 18% reported current, 6% intermittent, and 76% no cannabis use at baseline; 88% reported 100% ART adherence. Current cannabis users were more likely to be <100% adherent than nonusers (adjusted risk ratio [aRR], 1.53 [95% CI, 1.11-2.10]). There was no association between ART adherence and current versus intermittent (aRR, 1.39 [95% CI, .85-2.28]) or intermittent versus no cannabis use (aRR, 1.04 [95% CI, .62-1.73]).

Conclusions

Among a cohort of older PWH, current cannabis users had a higher risk of <100% ART adherence compared to nonusers. These findings have important clinical implications as suboptimal ART adherence is associated with ART drug resistance, virologic failure, and elevated risk for mortality. Further research is needed to elucidate the mechanisms by which cannabis use decreases ART adherence in older PWH and to advance the development of more efficacious methods to mitigate nonadherence in this vulnerable population.

Stakeholder views of services for children and adolescents with obesity: Mega-ethnography of qualitative syntheses

OBJECTIVE

The efficacy of services for children and adolescents with obesity is well researched, but this review describes what actually matters to stakeholders (children, caregivers, and professionals) in relation to such services.

METHODS

A mega-ethnography, an innovative review-of-reviews approach that uses conceptual findings as primary data, was performed. Twelve bibliographic databases (2010-2020) were searched for reviews that considered the values and preferences of stakeholders concerning services or interventions (diet, exercise, lifestyle) that targeted children and adolescents with obesity.

RESULTS

From 485 citations, 17 relevant reviews were identified. The synthesis found that the perceived need to address obesity is determined by subjective norms of weight and interactions with health professionals. Children's and caregivers' participation in obesity management services is shaped by their response to content, acceptability, and perceived benefits and demands. Whether they continue with and complete an intervention are determined by its perceived success, beyond just weight loss, including behavior change, enhanced self-esteem, and the provision of timely and relevant support.

CONCLUSIONS

Obesity management services must be promoted in a sensitive manner and must be tailored, be varied, and make positive use of family and schools if children and caregivers are to seek and actively engage with them.

Storyboarding HIV Infected Young People's Adherence to Antiretroviral Therapy in Lower- to Upper Middle-Income Countries: A New-Materialist Qualitative Evidence Synthesis

Young people living with perinatal infections of Human Immunodeficiency Virus (YLPHIV) face a chronic disease, with treatment including adherence to lifelong antiretroviral treatment (ART). The aim of this QES was to explore adherence to ART for YLPHIV as an assemblage within the framework of the biopsychosocial model with a new materialist perspective. We searched up to November 2021 and followed the ENTREQ and Cochrane guidelines for QES. All screening, data extraction, and critical appraisal were done in duplicate. We analysed and interpreted the findings innovatively by creating images of meaning, a storyboard, and storylines. We then reported the findings in a first-person narrative story. We included 47 studies and identified 9 storylines. We found that treatment adherence has less to do with humans' preferences, motivations, needs, and dispositions and more to do with how bodies, viruses, things, ideas, institutions, environments, social processes, and social structures assemble. This QES highlights that adherence to ART for YLPHIV is a multisensorial experience in a multi-agentic world. Future research into rethinking the linear and casual inferences we are accustomed to in evidence-based health care is needed if we are to adopt multidisciplinary approaches to address pressing issues such as adherence to ART.

Identifying individual enablers and barriers to the use of digital technology for the self-management of long-term conditions by older adults

Evidence suggests that much of the digital technology available and provided to older adults to enable self-management of long-term conditions is under-utilised. This research focuses on three conditions prevalent amongst older adults: diabetes, dementia and chronic kidney disease and explores the individual enablers and barriers to the use of digital self-management technology. The paper reports findings from a series of three systematic reviews of qualitative research (qualitative evidence syntheses). These reviews informed the design of a Delphi study. The first round of the Delphi involving 15 expert interviews is reported. The findings highlight common themes across the three conditions: how technology is used; barriers to use; assessing individual needs when selecting technology; support requirements; multi-functional self-management technologies; trust, privacy and data sharing; achieving accessible and aspirational design. Some emerging recommendations have been suggested to guide the design, and provision of technology to older adults. These will extended and refined through subsequent rounds of the Delphi method.

Translational framework for implementation evaluation and research: Protocol for a qualitative systematic review of studies informed by Normalization Process Theory (NPT) [version 1; peer review: 2 approved]

BACKGROUND

Normalization Process Theory (NPT) identifies mechanisms that have been demonstrated to play an important role in implementation processes. It is now widely used to inform feasibility, process evaluation, and implementation studies in healthcare and other areas of work. This qualitative synthesis of NPT studies aims to better understand how NPT explains observed and reported implementation processes, and to explore the ways in which its constructs explain the implementability, enacting and sustainment of complex healthcare interventions.

METHODS

We will systematically search Scopus, PubMed and Web of Science databases and use the Google Scholar search engine for citations of key papers in which NPT was developed. This will identify English language peer-reviewed articles in scientific journals reporting (a) primary qualitative or mixed methods studies; or, (b) qualitative or mixed methods evidence syntheses in which NPT was the primary analytic framework. Studies may be conducted in any healthcare setting, published between June 2006 and 31 December 2021. We will perform a qualitative synthesis of included studies using two parallel methods: (i) directed content analysis based on an already developed coding manual; and (ii) unsupervised textual analysis using Leximancer® topic modelling software.

OTHER

We will disseminate results of the review using peer reviewed publications, conference and seminar presentations, and social media (Facebook and Twitter) channels. The primary source of funding is the National Institute for Health Research ARC North Thames. No human subjects or personal data are involved and no ethical issues are anticipated.

"Deadly", "fierce", "shameful": notions of antiretroviral therapy, stigma and masculinities intersecting men's life-course in Blantyre, Malawi

BACKGROUND

Stigma and masculinity represent persistent barriers in delivering successful HIV interventions to men. Our study examined community perceptions of HIV and anti-retroviral therapy (ART) and their implications for men on ART across the life course in Blantyre, Malawi.

METHODS

Our qualitative study is based on 72 face-to-face semi-structured interviews. Participants were selected purposively and included men on ART (with suppressed and unsuppressed viral loads), adult male community members irrespective of HIV status and other HIV stakeholders such as health personnel and program implementers. Interviews were conducted in Chichewa and English, transcribed verbatim and analyzed thematically in NVivo 12. We applied the socio-ecological model as our theoretical framework as well as a "life-course" perspective.

RESULTS

Our findings highlight lingering negative perceptions towards ART in general and towards PLHIV irrespective of viral load suppression. With intersecting notions of masculinity and stigma, men's descriptions of anticipated stigma in their relationships and when visiting health facilities dominated. Stigma was experienced at the personal, interpersonal, facility and community level. Yet, men living with HIV were perceived differently throughout the life-course, with young sexually active men seen as the most stigmatized group and older men seen as drawing resilience from a greater range of masculine norms. Some men of all ages displayed "transformative" masculinities independent of stigma and community expectations.

CONCLUSIONS

We propose the "life-course" as a useful concept for studies on masculinity, HIV and stigma. Considering gendered constructions of "respectable" midlife-older age vis-à-vis younger age, and how they influence stigma as well as uptake and adherence to ART might lead to more targeted services for men that build on "transformative masculinities".

High residual inflammation despite HIV viral suppression: Lessons learned from real-time adherence monitoring among people with HIV in Africa

BACKGROUND

Lower antiretroviral therapy (ART) adherence is associated with higher systemic inflammation in virally suppressed people with HIV (PWH); however, previous studies have mostly relied on subjective adherence measures and have not assessed this association by disease stage upon ART initiation.

METHODS

In the Monitoring Early Treatment Adherence study, adherence was monitored electronically in real time among adult, treatment-naïve PWH in Uganda and South Africa who initiated tenofovir disoproxil fumarate/emtricitabine/efavirenz during early-stage (CD4 > 350 cells/µL) or late-stage (CD4 < 200 cells/µL) disease. Participants who achieved viral suppression (< 400 copies/mL) at 6 months and remained suppressed after 12 months were analysed. The association between average ART adherence and plasma concentrations of interleukin 6 (IL-6), soluble CD14 (sCD14) and D-dimer was evaluated using adjusted multivariable linear regression, stratified by disease stage.

RESULTS

In all, 488 PWH (61% women, mean age 35 years) were included in the analysis. Median ART adherence overall was 87%. In adjusted models, every 10% increase in average adherence was associated with a 3.0% decrease in IL-6 [95% confidence interval (CI): -5.9 to -0.01, p = 0.05] at 12 months. This relationship was observed in PWH with both early-stage (5.9%, 95% CI: -10.1 to -1.6, p = 0.009) and late-stage disease (3.7%, 95% CI: -7.2 to -0.2, p = 0.039). No significant associations were found with sCD14 or D-dimer.

CONCLUSIONS

Objective ART adherence measurement was inversely associated with systemic inflammation in PWH who achieved viral suppression after ART initiation in sub-Saharan Africa, with a greater association in those with early-stage HIV. This finding underscores the importance of ART adherence beyond establishing viral suppression.
