Implementation outcomes and strategies for depression interventions in low- and middle-income countries: a systematic review

Mental health care cascade performance and associated factors: longitudinal analyses of routine Ministry of Health services in Mozambique

ABSTRACT

Introduction

Mental, neurological and substance use (MNS) disorders are leading causes of disability worldwide. Nevertheless, limited research exists regarding MNS health system performance across the care cascade and associated patient characteristics in low-income and middle-income countries (LMICs) such as Mozambique.

Methods

We used baseline data from an ongoing randomised controlled trial, collected across 16 outpatient clinics on variables of sex, age, marital status, tuberculosis and HIV status, alcohol and drug use, suicidal ideation, pregnancy and MNS diagnosis. Mixed-effects multivariable regression was used to examine factors associated with patient functional improvement or low functional impairment measured by a standardised disability questionnaire.

Results

From February to September 2022, there were 4323 patient visits, of which 65.9% (n=2851) were attended on time (±5 days), 41.4% (n=1793) had medication adherence and 30.5% (n=1321) achieved a functional impairment score <10 or 50% improvement from baseline. Patients 15-18 years old had 60% lower odds of demonstrating functional improvement or low functional impairment during a follow-up visit compared with those 26-35 years old (95% CI: 0.19, 0.85). Compared with single persons, those in a domestic union had 3.3 times higher odds of demonstrating functional improvement or low functional impairment (95% CI: 1.8, 6.1). Individuals expressing suicidal ideation had 85% lower odds of demonstrating functional improvement than those without suicidal ideation (95% CI: 0.02, 0.91). For patients new to treatment, each additional visit was associated with a mean reduction in functional impairment of 0.62 points (95% CI: -0.76, -0.47).

Conclusions

This analysis revealed gaps in patients reaching functional improvement or low functional impairment in outpatient MNS care in Mozambique. Gaps were more pronounced for patients who are ≤18 years of age, single or expressing suicidal ideation. Implementation strategies to optimise patient outcomes are needed as nascent mental health systems are scaled-up in Mozambique and other similar LMICs.

Development of a remote implementation support strategy to enhance integration of depression treatment into primary care settings in rural India

Introduction

Contextually responsive implementation support strategies are needed to enhance the integration of mental health services into primary health care. Technical assistance is widely used as a core "capacity building" strategy, primarily for increasing the motivation and capacity of individuals (e.g., frontline workers) to adopt evidence-based interventions in healthcare settings. This article documents the systematic design of a technical assistance strategy for supporting primary care staff (e.g., nurses) in integrating depression care, from screening to treatment, aligned with a non-communicable disease program across seven health facilities in the Sehore District of Madhya Pradesh, India.

Methods

We conducted a mapping exercise of local health facilities with dedicated staff and a literature review to inform the development of the technical assistance strategy.

Results

Reporting guidelines guided the structure of the strategy protocol. The evidence-supported strategy, called Remote Coaching Support, is tailored to the local setting. It uses quality improvement methods like the Plan-Do-Act-Study cycle and training materials to help coaches deliver support remotely via video/phone-based calls and WhatsApp messaging with the overall goal of increasing uptake and fidelity of depression screening and referral among primary care staff in alignment with an existing non-communicable diseases program.

Conclusion

The development of Remote Coaching Support involved iterative improvements through team meetings and practice-training feedback, though limitations exist due to a lack of systematic implementation standards, especially in this setting. This strategy will be tested in increasing scales to refine its application, with effectiveness and acceptability results to be evaluated in a randomized control trial.

A learning health systems approach to scaling up an evidence-based intervention for integrated primary mental healthcare case finding and referral in South Africa

Despite progress in the development and evaluation of evidence-based primary mental health interventions in low-income and middle-income countries, implementation and scale-up efforts have had mixed results. Considerable gaps remain in the effective translation of research knowledge into routine health system practices, largely due to real-world contextual constraints on implementation and scale-up efforts. The Southern African Research Consortium for Mental Health Integration (S-MhINT) programme used implementation research to strengthen the implementation of an evidence-based integrated collaborative depression care model for primary healthcare (PHC) services in South Africa. To facilitate the scale-up of this model from a testing site to the whole province of KwaZulu-Natal, a capacity building programme was embedded within the Alliance for Health Policy and Systems Research (AHPSR) learning health systems (LHS) approach. The paper discusses efforts to scale up and embed case finding and referral elements of the S-MhINT package within routine PHC. Data from semistructured interviews, a focus group discussion, proceedings from participatory workshops and outputs from the application of continuous quality improvement (CQI) cycles were thematically analysed using the AHPSR LHS framework. Learning particularly occurred through information sharing at routine participatory workshops, which also offered mutual deliberation following periods of applying CQI tools to emergent problems. Individual-level, single-loop learning seemed to be particularly observable elements of the AHPSR LHS framework. Ultimately, our experience suggests that successful scale-up requires strong and sustained relationships between researchers, policy-makers and implementers, investments into learning platforms and organisational participation across all levels to ensure ownership and acceptance of learning processes.

Remote coaching for supporting the implementation of treatment for depression in primary care in Madhya Pradesh, India: protocol for a cluster randomized controlled trial

Background

Upwards of ninety percent of individuals living with depression in India do not have access to evidence-based treatments, especially in rural areas. Integrating these treatments into primary care is essential for bridging this care gap. This trial aims to evaluate whether a remote coaching implementation support strategy, referred to as Enhanced Implementation Support, is superior to routine support, referred to as Routine Implementation Support, in supporting the delivery of collaborative depression care in rural primary care centers.

Methods

Employing a cluster-randomized hybrid type-III implementation trial design, 14 primary care facilities in Sehore district, Madhya Pradesh, will implement a collaborative depression care package based on the WHO's mhGAP program. Facilities will be randomized to either Enhanced Implementation Support or the Routine Implementation Support control condition. Enhanced Implementation Support consists of remote coaching and technical assistance, supplemented with in-person visits, and guided by the Plan-Do-Study-Act implementation cycles. The primary implementation outcome is the proportion of outpatients screened for depression by facility staff, with secondary outcomes including the proportions of outpatients who screen positive for depression, are referred to the medical officer, and initiate treatment. Secondary patient outcomes include proportion of patients who achieve reduction in depression symptom severity at 3-month follow up. Acceptability, feasibility, and fidelity of the depression care package will be assessed through routine observations collected during field visits, facility audits, and qualitative exit interviews with facility staff. Costs of delivering the Enhanced Implementation Support strategy will also be estimated.

Discussion

This trial can inform efforts to integrate depression care in rural primary care facilities in a low-resource setting, and illuminate whether external coaching support is superior relative to existing implementation support for achieving these goals.

Implementation Strategies for Quality Improvement in Palliative Care: A Scoping Review

BACKGROUND

Quality improvement (QI) programs based on person-centred outcome measures (PCOMs) play an important role in promoting optimal palliative care. However, routine use of PCOMs has been slow and difficult to implement, including within QI programs.

OBJECTIVE

This study aimed to identify implementation strategies that support the implementation of PCOMs as routine practice in hospital-based palliative care, as well as the implementation theories, models and frameworks (TMFs) guiding the design of these implementation strategies.

METHODS

A scoping review was conducted in accordance with the Joanna Briggs Institute (JBI) Scoping Review framework. Four databases (Medline, CINAHL, Scopus and PubMed) were systematically searched for literature published between 1 January 1990 and 8 March 2024.

RESULTS

One hundred and fifteen unique implementation strategies, identified from 11 included studies, were mapped onto the 73 Expert Recommendations for Implementing Change (ERIC) discrete implementation strategies, covering 52% of the ERIC strategies. The most commonly used categories were train and educate stakeholders, and support clinicians, followed by develop stakeholder interrelationships and use evaluation and iterative strategies. Three key themes emerged: what to do; how to do it; and who to do it with. Only four studies employed TMFs to guide the design of the implementation strategies in this review.

CONCLUSIONS

To promote the implementation of PCOM-based QI programs, strategies should be developed based on identified/potential barriers and facilitators by using rigorous TMFs. The components of the implementation strategies must be reported transparently and consistently to enable replication and measurement in future research and practice.

PATIENT AND PUBLIC CONTRIBUTION

This scoping review does not directly involve patients or the general public in its design or execution. However, it is part of an implementation study aimed at integrating the Palliative Care Outcome Collaboration (PCOC) model into routine clinical practice at a cancer hospital in China. Before the formal implementation, palliative care professionals from this hospital highlighted the need for a comprehensive analysis of existing evidence to support the effective adoption of the PCOC model in their specific clinical setting.

Cognitive therapy for depression in tuberculosis treatment: protocol for multicentre pragmatic parallel arm randomised control trial with an internal pilot

INTRODUCTION AND OBJECTIVES

There is an unmet need to develop high-quality evidence addressing tuberculosis (TB)-related mental health comorbidity, particularly in the context of lower-middle-income countries. This study aims to examine the effectiveness and cost-effectiveness of cognitive behavioural therapy (CBT) versus enhanced treatment as usual (ETAU) in improving depressive symptoms in people with TB and comorbid depression, enhancing adherence with anti-TB treatment (ATT) and its implementation in the real-world setting of Pakistan.

METHODS

We will conduct a pragmatic parallel arm randomised control trial with an internal pilot. A brief psychological intervention based on CBT has been developed using a combination of qualitative and ethnographic studies. The inbuilt pilot trial will have a sample size of 80, while we plan to recruit 560 (280 per arm) participants in the definitive trial. Participants who started on ATT within 1 month of diagnosis for pulmonary and extrapulmonary TB or multidrug resistant TB (MDR-TB) and meeting the criteria for depression on Patient Health Questionnaire-9 (PHQ-9) will be randomised with 1:1 allocation to receive six sessions of CBT (delivered by TB healthcare workers) or ETAU. Data on the feasibility outcomes of the pilot will be considered to proceed with the definitive trial. Participants will be assessed (by a blinded assessor) for the following main trial primary outcomes: (1) severity of depression using PHQ-9 scale (interviewer-administered questionnaire) at baseline, weeks 8, 24 and 32 postrandomisation and (2) ATT at baseline and week 24 at the end of ATT therapy.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from Keele University Research Ethics Committee (ref: 2023-0599-792), Khyber Medical University Ethical Review Board (ref: DIR/KMU-EB/CT/000990) and National Bioethics Committee Pakistan (ref: No.4-87/NBC-998/23/587). The results of this study will be reported in peer-reviewed journals and academic conferences and disseminated to stakeholders and policymakers.

Development of an Implementation Strategy Tailored to Deliver Evidence-Based and Person-Centred Nursing Care for Patients with Community-Acquired Pneumonia: An Intervention Mapping Approach

Community-acquired pneumonia is a serious public health problem, and more so in older patients, leading to high morbidity and mortality. However, this problem can be reduced by optimising in-hospital nursing care. Accordingly, this study describes a systematic process of designing and developing a tailored theory- and research-based implementation strategy that supports registered nurses (RNs) in delivering evidence-based and person-centred care for this patient population in a hospital setting. The implementation strategy was developed by completing the six steps of the Intervention Mapping framework: (1) developing a logic model of the problem and (2) a logic model of change by defining performance and change objectives, (3) designing implementation strategy interventions by selecting theory-based change methods, (4) planning the interventions and producing materials through a co-design approach, (5) developing a structured plan for adoption, maintenance and implementation and (6) developing an evaluation plan. This method can serve as a guide to (1) target behavioural and environmental barriers hindering the delivery of nursing care in local clinical practice, (2) support evidence uptake, (3) support RNs in the delivery of nursing care according to individual patient needs and thereby (4) optimise health-related patient outcomes.

Strengthening integrated depression services within routine primary health care using the RE-AIM framework in South Africa

Integration of mental health into routine primary health care (PHC) services in low-and middle-income countries is globally accepted to improve health outcomes of other conditions and narrow the mental health treatment gap. Yet implementation remains a challenge. The aim of this study was to identify implementation strategies that improve implementation outcomes of an evidence-based depression care collaborative implementation model integrated with routine PHC clinic services in South Africa. An iterative, quasi-experimental, observational implementation research design, incorporating the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework, was applied to evaluate implementation outcomes of a strengthened package of implementation strategies (stage two) compared with an initial evaluation of the model (stage one). The first stage package was implemented and evaluated in 10 PHC clinics and the second stage strengthened package in 19 PHC clinics (inclusive of the initial 10 clinics) in one resource-scarce district in the province of KwaZulu-Natal, South Africa. Diagnosed service users were more likely to be referred for counselling treatment in the second stage compared with stage one (OR 23.15, SE = 18.03, z = 4.04, 95%CI [5.03-106.49], p < .001). Training in and use of a validated, mandated mental health screening tool, including on-site educational outreach and technical support visits, was an important promoter of nurse-level diagnosis rates (OR 3.75, 95% CI [1.19, 11.80], p = 0.02). Nurses who perceived the integrated care model as acceptable were also more likely to successfully diagnose patients (OR 2.57, 95% CI [1.03-6.40], p = 0.043). Consistent availability of a clinic counsellor was associated with a greater probability of referral (OR 5.9, 95%CI [1.29-27.75], p = 0.022). Treatment uptake among referred service users remained a concern across both stages, with inconsistent co-located counselling services associated with poor uptake. The importance of implementation research for strengthening implementation strategies along the cascade of care for integrating depression care within routine PHC services is highlighted.

Implementation measurement in global mental health: Results from a modified Delphi panel and investigator survey

Limited guidance exists to support investigators in the choice, adaptation, validation and use of implementation measures for global mental health implementation research. Our objectives were to develop consensus on best practices for implementation measurement and identify strengths and opportunities in current practice. We convened seven expert panelists. Participants rated approaches to measure adaptation and validation according to appropriateness and feasibility. Follow-up interviews were conducted and a group discussion was held. We then surveyed investigators who have used quantitative implementation measures in global mental health implementation research. Participants described their use of implementation measures, including approaches to adaptation and validation, alongside challenges and opportunities. Panelists agreed that investigators could rely on evidence of a measure's validity, reliability and dimensionality from similar contexts. Panelists did not reach consensus on whether to establish the pragmatic qualities of measures in novel settings. Survey respondents (n = 28) most commonly reported using the Consolidated Framework for Implementation Research Inner Setting Measures (n = 9) and the Program Assessment Sustainability Tool (n = 5). All reported adapting measures to their settings; only two reported validating their measures. These results will support guidance for implementation measurement in support of mental health services in diverse global settings.

Application of the Expert Recommendations for Implementing Change (ERIC) compilation of strategies to health intervention implementation in low- and middle-income countries: a systematic review

BACKGROUND

The Expert Recommendations for Implementing Change (ERIC) project developed a compilation of implementation strategies that are intended to standardize reporting and evaluation. Little is known about the application of ERIC in low- and middle-income countries (LMICs). We systematically reviewed the literature on the use and specification of ERIC strategies for health intervention implementation in LMICs to identify gaps and inform future research.

METHODS

We searched peer-reviewed articles published through March 2023 in any language that (1) were conducted in an LMIC and (2) cited seminal ERIC articles or (3) mentioned ERIC in the title or abstract. Two co-authors independently screened all titles, abstracts, and full-text articles, then abstracted study, intervention, and implementation strategy characteristics of included studies.

RESULTS

The final sample included 60 studies describing research from all world regions, with over 30% published in the final year of our review period. Most studies took place in healthcare settings (n = 52, 86.7%), while 11 (18.2%) took place in community settings and four (6.7%) at the policy level. Across studies, 548 distinct implementation strategies were identified with a median of six strategies (range 1-46 strategies) included in each study. Most studies (n = 32, 53.3%) explicitly matched implementation strategies used for the ERIC compilation. Among those that did, 64 (87.3%) of the 73 ERIC strategies were represented. Many of the strategies not cited included those that target systems- or policy-level barriers. Nearly 85% of strategies included some component of strategy specification, though most only included specification of their action (75.2%), actor (57.3%), and action target (60.8%). A minority of studies employed randomized trials or high-quality quasi-experimental designs; only one study evaluated implementation strategy effectiveness.

CONCLUSIONS

While ERIC use in LMICs is rapidly growing, its application has not been consistent nor commonly used to test strategy effectiveness. Research in LMICs must better specify strategies and evaluate their impact on outcomes. Moreover, strategies that are tested need to be better specified, so they may be compared across contexts. Finally, strategies targeting policy-, systems-, and community-level determinants should be further explored.

A theory of change for community-initiated mental health care in the United States

Mental health service delivery needs radical reimagination in the United States where unmet needs for care remain large and most metrics on the burden of mental health problems have worsened, despite significant numbers of mental health professionals, spending on service provision and research. The COVID-19 pandemic has exacerbated the need for mental health care. One path to a radical reimagination is "Community Initiated Care (CIC)" which equips and empowers communities to address by providing brief psychosocial interventions by people in community settings. We co-developed a theory of change (ToC) for CIC with 24 stakeholders including representatives from community-based, advocacy, philanthropic and faith-based organizations to understand how CIC could be developed and adapted for specific contexts. We present a ToC which describes ways in which the CIC initiative can promote and strengthen mental health in communities in the United States with respect to community organization and leadership; community care and inclusion and normalizing mental health. We propose 10 strategies as part of CIC and propose a way forward for implementation and evaluation. This CIC model is a local, tailored approach which can expand the role of community members to strengthen our response to mental health needs in the United States.

Addressing the Know-Do Gap in Adolescent HIV: Framing and Measuring Implementation Determinants, Outcomes, and Strategies in the AHISA Network

Implementation science (IS) uses systematic methods to close gaps between research and practice by identifying and addressing barriers to implementation of evidence-based interventions (EBIs). To reach UNAIDS HIV targets, IS can support programs to reach vulnerable populations and achieve sustainability. We studied the application of IS methods in 36 study protocols that were part of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA). Protocols focused on youth, caregivers, or healthcare workers in high HIV-burden African countries and evaluated medication, clinical and behavioral/social EBIs. All studies measured clinical outcomes and implementation science outcomes; most focused on early implementation outcomes of acceptability (81%), reach (47%), and feasibility (44%). Only 53% used an implementation science framework/theory. Most studies (72%) evaluated implementation strategies. Some developed and tested strategies, while others adapted an EBI/strategy. Harmonizing IS approaches allows cross study learning and optimization of delivery of EBIs and could support attainment of HIV goals.

Scaling up community-delivered mental health support and care: A landscape analysis

Introduction

The mental health crisis has caused widespread suffering and has been further exacerbated by the COVID-19 pandemic. Marginalized groups are especially affected, with many concerns rooted in social determinants of mental health. To stem this tide of suffering, consideration of approaches outside the traditional biomedical model will be necessary. Drawing from task-sharing models of mental health care that have been pioneered in low-resource settings, community-initiated care (CIC) represents a potentially promising collection of approaches. This landscape analysis seeks to identify examples of CIC that have been implemented outside of the research context, with the aim of identifying barriers and facilitators of scale up.

Methods

A narrative review approach was used for this landscape analysis in which the PubMed database was searched and further supplemented with Google Scholar. Promising programs were then discussed over multiple rounds of meetings with the research team, consisting of collaborators with varied experiences in mental health. Using the selection criteria and feedback derived from group meetings, a final list of programs was identified and summarized according to common characteristics and features.

Results

The initial PubMed search yielded 16 results, supplemented by review of the first 100 entries in Google Scholar. Through 5 follow-up meetings among team members, consensus was reached on a final list of 9 programs, which were grouped into three categories based on similar themes and topics: (1) approaches for the delivery of psychosocial interventions; (2) public health and integrative approaches to mental health; and (3) approaches for addressing youth mental health. Key facilitators to scale up included the importance of sustainable financing and human resources, addressing social determinants and stigma, engaging diverse stakeholders, leveraging existing health infrastructure, using sustainable training models, ensuring cultural relevance and appropriateness, and leveraging digital technologies.

Discussion

This landscape analysis, though not an exhaustive summary of the literature, describes promising examples of efforts to scale up CIC outside of the research context. Going forward, it will be necessary to mobilize stakeholders at the community, health system, and government levels to effectively promote CIC.

Toward 90-90-90 Goals for Global Mental Health

This Viewpoint discusses the adoption of 90-90-90 goals for global mental health, specifically targeting neurologic and substance use disorders, to prioritize mental health quality improvement within existing health services and destigmatize these conditions to promote treatment.

Using the RE-AIM framework to evaluate the implementation of scaling-up the Friendship Bench in Zimbabwe - a quantitative observational study

BACKGROUND

This study aimed to evaluate the real-world implementation of the Friendship Bench (FB) - an evidence-based brief psychological intervention delivered by community health workers (CHWs) - three years after its implementation in three city health departments in Zimbabwe. Implementation sites were evaluated according to their current performance using the RE-AIM framework making this one of the first evaluations of a scaled-up evidence-based psychological intervention in sub-Saharan Africa (SSA).

METHODS

Using the RE-AIM guide ( www.re-aim.org ), the authors designed quantitative indicators based on existing FB implementation data. Thirty-six primary health care clinics (PHC) in Harare (n=28), Chitungwiza (n=4) and Gweru (n=4) were included. Among these clinics 20 were large comprehensive health care centers, 7 medium (mostly maternal and child healthcare) and 9 small clinics (basic medical care and acting as referral clinic). Existing data from these clinics, added to additionally collected data through interviews and field observations were used to investigate and compare the performance of the FB across clinics. The focus was on the RE-AIM domains of Reach, Adoption, and Implementation.

RESULTS

Small clinics achieved 34% reach, compared to large (15%) and medium clinics (9%). Adoption was high in all clinic types, ranging from 59% to 71%. Small clinics led the implementation domain with 53%, followed by medium sized clinics 43% and large clinics 40%. Small clinics performed better in all indicators and differences in performance between small and large clinics were significant. Program activity and data quality depends on ongoing support for delivering agents and buy-in from health authorities.

CONCLUSION

The Friendship Bench program was implemented over three years transitioning from a research-based implementation program to one led locally. The Reach domain showed the largest gap across clinics where larger clinics performed poorly relative to smaller clinics and should be a target for future implementation improvements. Program data needs to be integrated into existing health information systems. Future studies should seek to optimize scale-up and sustainment strategies to maintain effective task-shared psychological interventions in SSA.

Community perspectives on the implementation of a group psychological intervention for adolescents with depression: A qualitative study in rural Nepal

Group-based psychological interventions could help to close the treatment gap for depression in low-resource settings, but implementation barriers exist. In Nepal we sought community members' perspectives on how to implement group interpersonal therapy for adolescents. We conducted qualitative interviews with 25 adolescents with depression (aged 13-18) and seven health and non-governmental organization workers, and four focus groups with non-depressed adolescents, four with parents/guardians, and two with teachers (126 participants total). Data were analyzed using the Framework Method. Participants recommended same-sex groups. School was the preferred location because it is accessible for adolescents and acceptable to parents. Adolescents wanted facilitators from their own community with good communication skills. They did not want parents or teachers to participate in groups but emphasized the need to inform parents and obtain their permission. Community members supported group psychological intervention. School-based psychological interventions facilitated by local people could be an acceptable option in rural Nepal.

Effectiveness and implementation outcomes for peer-delivered mental health interventions in low- and middle-income countries: a mixed-methods systematic review

PURPOSE

This review aimed to evaluate interventions led by peer counselors (PCs) for adults with common mental disorders in low- and middle-income countries (LMICs) along indices of overall effectiveness and key implementation outcomes (acceptability, feasibility, cost, fidelity, sustainability).

METHODS

This review followed a mixed-methods systematic review design. MEDLINE/PubMed, Embase, PsycINFO, and Global Health databases were searched for PC-led interventions for adults in LMICs targeting depressive and/or anxiety disorders or PTSD. Quantitative data was narratively synthesized, and qualitative data was thematically synthesized separately. The results from the qualitative and quantitative syntheses were then combined in a cross-study synthesis.

RESULTS

Twenty-four papers describing thirteen PC-led interventions were included for review. Narrative synthesis results indicated mixed effectiveness of PC-led interventions in reducing depressive, anxiety, PTSD symptoms and high PC competency. Thematic synthesis revealed five descriptive themes: (1) Preferred PC characteristics; (2) Incentives and motivation for PCs; (3) Barriers to PC-led intervention implementation; (4) Helpful supervision/training practices; and (5) Overall high acceptability of PC-led interventions. Cross-study synthesis revealed high acceptability, feasibility, and fidelity, but cost and sustainability outcomes were underreported in included papers.

CONCLUSION

PC-led interventions seem to show initial promise in terms of effectiveness, acceptability, feasibility, cost, fidelity, and sustainability. Future research should focus on standardizing measurements of implementation outcomes to facilitate cross-study analysis. Additional empirical attention should be paid to underrepresented implementation outcomes (e.g., cost, sustainability). Finally, researchers should adopt a participatory approach that elevates the perspectives of PCs throughout all stages of the implementation process.

Patient and provider perceptions of a peer-delivered intervention ('Khanya') to improve anti-retroviral adherence and substance use in South Africa: a mixed methods analysis

Background

Despite a high prevalence of problematic substance use among people living with HIV in South Africa, there remains limited access to substance use services within the HIV care system. To address this gap, our team previously developed and adapted a six-session, peer-delivered problem-solving and behavioral activation-based intervention (Khanya) to improve HIV medication adherence and reduce substance use in Cape Town. This study evaluated patient and provider perspectives on the intervention to inform implementation and future adaptation.

Methods

Following intervention completion, we conducted semi-structured individual interviews with patients (n = 23) and providers (n = 9) to understand perspectives on the feasibility, acceptability, and appropriateness of Khanya and its implementation by a peer. Patients also quantitatively ranked the usefulness of individual intervention components (problem solving for medication adherence 'Life-Steps', behavioral activation, mindfulness training, and relapse prevention) at post-treatment and six months follow-up, which we triangulated with qualitative feedback to examine convergence and divergence across methods.

Results

Patients and providers reported high overall acceptability, feasibility, and appropriateness of Khanya, although there were several feasibility challenges. Mindfulness and Life-Steps were identified as particularly acceptable, feasible, and appropriate components by patients across methods, whereas relapse prevention strategies were less salient. Behavioral activation results were less consistent across methods.

Conclusions

Findings underscore the importance of examining patients' perspectives on specific intervention components within intervention packages. While mindfulness training and peer delivery models were positively perceived by consumers, they are rarely used within task-shared behavioral interventions in low- and middle-income countries.

Implementation and scalability of a digital intervention to reduce depressive symptoms in people with diabetes, hypertension or both in Brazil and Peru: a qualitative study of health system's stakeholders' perspectives

Two randomized controlled trials (RCTs) in Brazil and Peru demonstrated the effectiveness of CONEMO, a digital intervention supported by trained nurses or nurse assistants (NAs), to reduce depressive symptoms in people with diabetes and/or hypertension. This paper extends the RCTs findings by reflecting on the conditions needed for its wider implementation in routine care services. A qualitative study using semi-structured interviews and content analysis was conducted with nurses/NAs, clinicians, healthcare administrators, and policymakers. Informants reported that CONEMO would be feasible to implement in their health services, but some conditions could be improved before its scale-up: reducing workloads of healthcare workers; raising mental health awareness among clinicians and administrators; being able to inform, deliver and accompany the intervention; assuring appropriate training and supervision of nurses/NAs; and supporting the use of technology in public health services and by patients, especially older ones. We discuss some suggestions on how to overcome these challenges.

Leveraging Stakeholder Engagement and Virtual Environments to Develop a Strategy for Implementation of Adolescent Depression Services Integrated Within Primary Care Clinics of Mozambique

Psychiatric disorders are the number one cause of disability in adolescents worldwide. Yet, in low- and middle-income countries (LMIC), where 90% of adolescents reside, mental health services are extremely limited, and the majority do not have access to treatment. Integration of mental health services within primary care of LMICs has been proposed as an efficient and sustainable way to close the adolescent mental health treatment gap. However, there is limited research on how to effectively implement integrated mental health care in LMIC. In the present study, we employed Implementation Mapping to develop a multilevel strategy for integrating adolescent depression services within primary care clinics of Maputo, Mozambique. Both in-person and virtual approaches for Implementation Mapping activities were used to support an international implementation planning partnership and promote the engagement of multilevel stakeholders. We identified determinants to implementation of mental health services for adolescents in LMIC across all levels of the Consolidated Framework for Implementation Research, of which of 25% were unique to adolescent-specific services. Through a series of stakeholder workshops focused on implementation strategy selection, prioritization, and specification, we then developed an implementation plan comprising 33 unique strategies that target determinants at the intervention, patient, provider, policy, and community levels. The implementation plan developed in this study will be evaluated for delivering adolescent depression services in Mozambican primary care and may serve as a model for other low-resource settings.

The case for prioritizing implementation strategy fidelity measurement: benefits and challenges

Implementation strategies are systematic approaches to improve the uptake and sustainability of evidence-based interventions. They frequently focus on changing provider behavior through the provision of interventions such as training, coaching, and audit-and-feedback. Implementation strategies often impact intermediate behavioral outcomes like provider guideline adherence, in turn improving patient outcomes. Fidelity of implementation strategy delivery is defined as the extent to which an implementation strategy is carried out as it was designed. Implementation strategy fidelity measurement is under-developed and under-reported, with the quality of reporting decreasing over time. Benefits of fidelity measurement include the exploration of the extent to which observed effects are moderated by fidelity, and critical information about Type-III research errors, or the likelihood that null findings result from implementation strategy fidelity failure. Reviews of implementation strategy efficacy often report wide variation across studies, commonly calling for increased implementation strategy fidelity measurement to help explain variations. Despite the methodological benefits of rigorous fidelity measurement, implementation researchers face multi-level challenges and complexities. Challenges include the measurement of a complex variable, multiple data collection modalities with varying precision and costs, and the need for fidelity measurement to change in-step with adaptations. In this position paper, we weigh these costs and benefits and ultimately contend that implementation strategy fidelity measurement and reporting should be improved in trials of implementation strategies. We offer pragmatic solutions for researchers to make immediate improvements like the use of mixed methods or innovative data collection and analysis techniques, the inclusion of implementation strategy fidelity assessment in reporting guidelines, and the staged development of fidelity tools across the evolution of an implementation strategy. We also call for additional research into the barriers and facilitators of implementation strategy fidelity measurement to further clarify the best path forward.

Public mental health: required actions to address implementation failure in the context of COVID-19

Mental disorders account for at least 18% of global disease burden, and the associated annual global costs are projected to be US$6 trillion by 2030. Evidence-based, cost-effective public mental health (PMH) interventions exist to prevent mental disorders from arising, prevent associated impacts of mental disorders (including through treatment), and promote mental wellbeing and resilience. However, only a small proportion of people with mental disorders receive minimally adequate treatment. Compared with treatment, there is even less coverage of interventions to prevent the associated impacts of mental disorders, prevent mental disorders from arising, or promote mental wellbeing and resilience. This implementation failure breaches the right to health, has increased during the COVID-19 pandemic, and results in preventable suffering, broad impacts, and associated economic costs. In this Health Policy paper, we outline specific actions to improve the coverage of PMH interventions, including PMH needs assessments, collaborative advocacy and leadership, PMH practice to inform policy and implementation, training and improvement of population literacy, settings-based and integrated approaches, use of digital technology, maximising existing resources, focus on high-return interventions, human rights approaches, legislation, and implementation research. Increased interest in PMH in populations and governments since the onset of the COVID-19 pandemic supports these actions. Improved implementation of PMH interventions can result in broad health, social, and economic impacts, even in the short-term, which support the achievement of a range of policy objectives, sustainable economic development, and recovery.

Roll-out of HIV pre-exposure prophylaxis: a gateway to mental health promotion

HIV remains a pressing global health problem, with 1.5 million new infections reported globally in 2020. HIV pre-exposure prophylaxis (PrEP) can lower the likelihood of HIV acquisition among populations at elevated risk, yet its global roll-out has been discouragingly slow. Psychosocial factors, such as co-occurring mental illness and substance use, are highly prevalent among populations likely to benefit from PrEP, and have been shown to undermine persistence and adherence. In this analysis, we review the high burden of mental health problems among PrEP candidates and contend that inattention to mental health stands to undermine efforts to implement PrEP on a global scale. We conclude that integration of mental health screening and treatment within PrEP scale-up efforts represents an important strategy for maximising PrEP effectiveness while addressing the high burden of mental illness among at-risk populations. As implementers seek to integrate mental health services within PrEP services, efforts to keep access to PrEP as low-threshold as possible should be maintained. Moreover, programmes should seek to implement mental health interventions that are sensitive to local resource constraints and seek to reduce intersecting stigmas associated with HIV and mental illness.

Economic threshold analysis of delivering a task-sharing treatment for common mental disorders at scale: the Friendship Bench, Zimbabwe

Background

Task-sharing treatment approaches offer a pragmatic approach to treating common mental disorders in low-income and middle-income countries (LMICs). The Friendship Bench (FB), developed in Zimbabwe with increasing adoption in other LMICs, is one example of this type of treatment model using lay health workers (LHWs) to deliver treatment.

Objective

To consider the level of treatment coverage required for a recent scale-up of the FB in Zimbabwe to be considered cost-effective.

Methods

A modelling-based deterministic threshold analysis conducted within a ‘cost-utility’ framework using a recommended cost-effectiveness threshold.

Findings

The FB would need to treat an additional 3413 service users (10 per active LHW per year) for its scale-up to be considered cost-effective. This assumes a level of treatment effect observed under clinical trial conditions. The associated incremental cost-effectiveness ratio was $191 per year lived with disability avoided, assuming treatment coverage levels reported during 2020. The required treatment coverage for a cost-effective outcome is within the level of treatment coverage observed during 2020 and remained so even when assuming significantly compromised levels of treatment effect.

Conclusions

The economic case for a scaled-up delivery of the FB appears convincing in principle and its adoption at scale in LMIC settings should be given serious consideration.

Clinical implications

Further evidence on the types of scale-up strategies that are likely to offer an effective and cost-effective means of sustaining required levels of treatment coverage will help focus efforts on approaches to scale-up that optimise resources invested in task-sharing programmes.

Evaluating context and interest in training in evidence-based mental health care: a qualitative investigation among healthcare providers in Kyiv, Ukraine

Objective

Increasing access to quality, evidence-based mental health treatments, including psychotherapy, is a global priority. Knowledge of factors associated with delivery settings is critical to ensure that new practices are appropriate and effectively adapted for novel settings. Understanding perceived needs for training and interest in ongoing education is one key factor. This qualitative study aimed to identify perspectives on contemporary evidence-based psychotherapies, perceived needs for mental health training, and existing barriers and facilitators to provision of mental health services in community clinics in Ukraine. Purposive and snowball sampling was used to recruit 18 physicians and psychologists employed in community clinics in Kyiv. A combination of free-listing and semi-structured interviews was used to collect data, which were thematically coded using emergent coding.

Results

Findings from this study indicated that participants recognize a need for improved mental health knowledge and training, as well as suggested interest and openness to learning short-term, structured psychological interventions. Additional barriers and existing strengths described by participants provide insight into possible factors that may impact future trainings in and implementation of modern mental health approaches.

Availability and Accessibility of Primary Care for the Remote, Rural, and Poor Population of Indonesia

Background: Adopting Universal Health Coverage for implementation of a national health insurance system [Jaminan Kesehatan Nasional (JKN)/Badan Penyelenggara Jaminan Sosial or the Indonesian National Social Health Insurance Scheme (BPJS)] targets the 255 million population of Indonesia. The availability, accessibility, and acceptance of healthcare services are the most important challenges during implementation. Referral behavior and the utilization of primary care structures for underserved (rural/remote regions) populations are key guiding elements. In this study, we provided the first assessment of BPJS implementation and its resulting implications for healthcare delivery based on the entire insurance dataset for the initial period of implementation, specifically focusing on poor and remote populations. Methods: Demographic, economic, and healthcare infrastructure information was obtained from public resources. Data about the JKN membership structure, performance information, and reimbursement were provided by the BPJS national head office. For analysis, an ANOVA was used to compare reimbursement indexes for primary healthcare (PHC) and advanced healthcare (AHC). The usage of primary care resources was analyzed by comparing clustered provinces and utilization indices differentiating poor [Penerima Bantuan Iur (PBI) membership] and non-poor populations (non-PBI). Factorial and canonical discrimination analyses were applied to identify the determinants of PHC structures. Results: Remote regions cover 27.8% of districts/municipalities. The distribution of the poor population and PBI members were highly correlated (r2 > 0.8; p < 0.001). Three clusters of provinces [remote high-poor (N = 13), remote low-poor (N = 15), non-remote (N = 5)] were identified. A discrimination analysis enabled the >82% correct cluster classification of infrastructure and human resources of health (HRH)-related factors. Standardized HRH (nurses and general practitioners [GP]) availability showed significant differences between clusters (p < 0.01), whereas the availability of hospital beds was weakly correlated. The usage of PHC was ~2-fold of AHC, while non-PBI members utilized AHC 4- to 5-fold more frequently than PBI members. Referral indices (r2 = 0.94; p < 0.001) for PBI, non-PBI, and AHC utilization rates (r2 = 0.53; p < 0.001) were highly correlated. Conclusion: Human resources of health availability were intensively related to the extent of the remote population but not the numbers of the poor population. The access points of PHC were mainly used by the poor population and in remote regions, whereas other population groups (non-PBI and non-Remote) preferred direct access to AHC. Guiding referral and the utilization of primary care will be key success factors for the effective and efficient usage of available healthcare infrastructures and the achievement of universal health coverage in Indonesia. The short-term development of JKN was recommended, with a focus on guiding referral behavior, especially in remote regions and for non-PBI members.

Optimising implementation strategies of the first scaleup of a primary care psychological intervention for common mental disorders in Sub-Saharan Africa: a mixed methods study protocol for the optimised Friendship Bench (OptFB)

INTRODUCTION

Common mental disorders (CMDs) are a leading cause of disability globally. CMDs are highly prevalent in Zimbabwe and have been addressed by an evidence-based, task-shifting psychological intervention called the Friendship Bench (FB). The task-shifted FB programme guides clients through problem-solving therapy. It was scaled up across 36 implementation sites in Zimbabwe in 2016.

METHODS AND ANALYSIS

This study will employ a mixed-method framework. It aims to: (1) use quantitative survey methodologies organised around the Reach, Effectiveness, Adoption and Implementation and Maintenance evaluation framework to assess the current scaleup of the FB intervention and classify 36 clinics according to levels of performance; (2) use qualitative focus group discussions and semistructured interviews organised around the Consolidated Framework for Implementation Research to analyse determinants of implementation success, as well as elucidate heterogeneity in implementation strategies through comparing high-performing and low-performing clinics; and (3) use the results from aims 1 and 2 to develop strategies to optimise the Friendship Bench intervention and apply this model in a cluster randomised controlled trial to evaluate potential improvements among low-performing clinics. The trial will be registered with the Pan African Clinical Trial Registry (www.pactr.org). The planned randomised controlled trial for the third research aim will be registered after completing aims one and two because the intervention is dependent on knowledge generated during these phases.

ETHICS AND DISSEMINATION

The research protocol received full authorisation from the Medical Research Council of Zimbabwe (MRCZ A/242). It is anticipated that changes in data collection tools and consent forms will take place at all three phases of the study and approval from MRCZ will be sought. All interview partners will be asked for informed consent. The research team will prioritise open-access publications to disseminate research results.

Implementation and Scale-Up of Integrated Depression Care in South Africa: An Observational Implementation Research Protocol

BACKGROUND

People with chronic general medical conditions who have comorbid depression experience poorer health outcomes. This problem has received scant attention in low- and middle-income countries. The aim of the ongoing study reported here is to refine and promote the scale-up of an evidence-based task-sharing collaborative care model, the Mental Health Integration (MhINT) program, to treat patients with comorbid depression and chronic disease in primary health care settings in South Africa.

METHODS

Adopting a learning-health-systems approach, this study uses an onsite, iterative observational implementation science design. Stage 1 comprises assessment of the original MhINT model under real-world conditions in an urban subdistrict in KwaZulu-Natal, South Africa, to inform refinement of the model and its implementation strategies. Stage 2 comprises assessment of the refined model across urban, semiurban, and rural contexts. In both stages, population-level effects are assessed by using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) evaluation framework with various sources of data, including secondary data collection and a patient cohort study (N=550). The Consolidated Framework for Implementation Research is used to understand contextual determinants of implementation success involving quantitative and qualitative interviews (stage 1, N=78; stage 2, N=282).

RESULTS

The study results will help refine intervention components and implementation strategies to enable scale-up of the MhINT model for depression in South Africa.

NEXT STEPS

Next steps include strengthening ongoing engagements with policy makers and managers, providing technical support for implementation, and building the capacity of policy makers and managers in implementation science to promote wider dissemination and sustainment of the intervention.

Optimizing treatment cascades for mental healthcare in Mozambique: preliminary effectiveness of the Systems Analysis and Improvement Approach for Mental Health (SAIA-MH)

Substantial investments are being made to scale-up access to mental healthcare in low- and middle-income countries, but less attention has been paid to quality and performance of nascent public-sector mental healthcare systems. This study tested the initial effectiveness of an implementation strategy to optimize routine outpatient mental healthcare cascade performance in Mozambique [the Systems Analysis and Improvement Approach for Mental Health (SAIA-MH)]. This study employed a pre-post design from September 2018 to August 2019 across four Ministry of Health clinics among 810 patients and 3234 outpatient mental health visits. Effectiveness outcomes evaluated progression through the care cascade, including: (1) initial diagnosis and medication selection; (2) enrolling in follow-up care; (3) returning after initial consultation within 60 days; (4) returning for follow-up visits on time; (5) returning for follow-up visits adherent to medication and (6) achieving function improvement. Clustered generalized linear models evaluated odds of completing cascade steps pre- vs post-intervention. Facilities prioritized improvements focused on the follow-up cascade, with 62.5% (10 of 16) monthly system modifications targeting medication adherence. At baseline, only 4.2% of patient visits achieved function improvement; during the 6 months of SAIA-MH implementation, this improved to 13.1% of patient visits. Multilevel logistic regression found increased odds of returning on time and adherent [aOR = 1.53, 95% CI (1.21, 1.94), P = 0.0004] and returning on time, adherent and with function improvement [aOR = 3.68, 95% CI (2.57, 5.44), P < 0.0001] after SAIA-MH implementation. No significant differences were observed regarding other cascade steps. The SAIA-MH implementation strategy shows promise for rapidly and significantly improving mental healthcare cascade outcomes, including the ultimate goal of patient function improvement. Given poor baseline mental healthcare cascade performance, there is an urgent need for evidence-based implementation strategies to optimize the performance of mental healthcare cascades in low- and middle-income countries.

Evaluating clinical outcomes of routinely delivered task-shared care for depression in rural Haiti

BACKGROUND

There is a growing literature in support of the effectiveness of task-shared mental health interventions in resource-limited settings globally. However, despite evidence that effect sizes are greater in research studies than actual care, the literature is sparse on the impact of such interventions as delivered in routine care. In this paper, we examine the clinical outcomes of routine depression care in a task-shared mental health system established in rural Haiti by the international health care organization Partners In Health, in collaboration with the Haitian Ministry of Health, following the 2010 earthquake.

METHODS

For patients seeking depression care betw|een January 2016 and December 2019, we conducted mixed-effects longitudinal regression to quantify the effect of depression visit dose on symptoms, incorporating interaction effects to examine the relationship between baseline severity and dose.

RESULTS

306 patients attended 2052 visits. Each visit was associated with an average reduction of 1.11 in depression score (range 0-39), controlling for sex, age, and days in treatment (95% CI -1.478 to -0.91; p < 0.001). Patients with more severe symptoms experienced greater improvement as a function of visits (p = 0.04). Psychotherapy was provided less frequently and medication more often than expected for patients with moderate symptoms.

CONCLUSIONS

Our findings support the potential positive impact of scaling up routine mental health services in low- and middle-income countries, despite greater than expected variability in service provision, as well as the importance of understanding potential barriers and facilitators to care as they occur in resource-limited settings.
