The costs of Suaahara II, a complex scaled-up multisectoral nutrition programme in Nepal.

Limited evidence exists on the costs of scaled-up multisectoral nutrition programmes. Such evidence is crucial to assess intervention value and affordability. Evidence is also lacking on the opportunity costs of implementers and participants engaging in community-level interventions. We help to fill this gap by estimating the full financial and economic costs of the United States Agency for International Development-funded Suaahara II (SII) programme, a scaled-up multisectoral nutrition programme in Nepal (2016-2023). We applied a standardized mixed methods costing approach to estimate total and unit costs over a 3.7-year implementation period. Financial expenditure data from national and subnational levels were combined with economic cost estimates assessed using in-depth interviews and focus group discussions with staff, volunteers, community members, and government partners in four representative districts. The average annual total cost was US$908,948 per district, with economic costs accounting for 47% of the costs. The annual unit cost was US$132 per programme participant (mother in the 1000-day period between conception and a child's second birthday) reached. Annual costs ranged from US$152 (mountains) to US$118 (plains) per programme participant. Personnel (63%) were the largest input cost driver, followed by supplies (11%). Community events (29%) and household counselling visits (17%) were the largest activity cost drivers. Volunteer cadres contributed significant time to the programme, with female community health volunteers spending a substantial amount of time (27 h per month) on SII activities. Multisectoral nutrition programmes can be costly, especially when taking into consideration volunteer and participant opportunity costs. This study provides much-needed evidence of the costs of scaled-up multisectoral nutrition programmes for future comparison against benefits.

Perinatal Depressive Symptoms and Viral Non-suppression Among a Prospective Cohort of Pregnant Women Living with HIV in Nigeria, Kenya, Uganda, and Tanzania.

Depression is common during pregnancy and is associated with reduced adherence to HIV-related care, though little is known about perinatal trajectories of depression and viral suppression among women living with HIV (WLHV) in sub-Saharan Africa. We sought to assess any association between perinatal depressive symptoms and viral non-suppression among WLWH. Depressive symptomatology and viral load data were collected every 6 months from WLWH enrolled in the African Cohort Study (AFRICOS; January 2013-February 2020). Generalized estimating equations modeled associations between depressive symptoms [Center for Epidemiological Studies Depression (CES-D) ≥ 16] and viral non-suppression. Of 1722 WLWH, 248 (14.4%) had at least one pregnancy (291 total) and for 61 pregnancies (21.0%), women reported depressive symptoms (13.4% pre-conception, 7.6% pregnancy, 5.5% one-year postpartum). Depressive symptomatology was associated with increased odds of viral non-suppression (aOR 2.2; 95% CI 1.2-4.0, p = 0.011). Identification and treatment of depression among women with HIV may improve HIV outcomes for mothers.

Assessing the Effectiveness of the Respecting the Circle of Life Project on Condom and Contraception Self-efficacy Among American Indian Youth.

Respecting the Circle of Life (RCL) is a teen pregnancy prevention program that was evaluated for effectiveness on sexual health risk behaviors through a two-arm randomized control trial (RCT) with American Indian (AI) youth ages 11-19. The objective of this study is to investigate the effects of RCL compared to a control group on items of condom and contraception self-efficacy. Linear regression analysis was used to compare differences in each item that included condom and contraception self-efficacy scales among the intervention and control participants at baseline, 3 and 9 months post intervention. Youth enrolled in the intervention reported higher levels of condom and contraception self-efficacy across almost all individual items. Exceptions include items related to partner negotiation of condom self-efficacy at 3 months (p = 0.227) and 9 months (p = 0.074) post intervention. Findings indicate RCL is effective at improving overall condom and contraception self-efficacy but did not impact the specific component of partner negotiation for either condom or contraception self-efficacy. This inquiry provides rationale to further explore components of RCL related to partner negotiation.

Alcohol Use and Antiretroviral Therapy Non-Adherence Among Adults Living with HIV/AIDS in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Antiretroviral therapy (ART) is efficacious in improving clinical outcomes among people living with HIV (PLWH) and reducing HIV transmission when taken regularly. Research examining modifiable factors associated with ART non-adherence is critical for informing novel intervention development in settings with high HIV prevalence. Alcohol use has been linked with ART non-adherence in studies in sub-Saharan Africa; however, no review has pooled estimates across studies. We reviewed studies of alcohol use and ART non-adherence conducted in sub-Saharan Africa. We searched PubMed, CINAHL, EMBASE, and PsycINFO through August 2019 with terms related to ART non-adherence, alcohol use, and sub-Saharan Africa. One author reviewed titles/abstracts (n = 754) and two authors reviewed full texts (n = 308) for inclusion. Discrepancies were resolved by group consensus. Studies were retained if they quantitatively measured associations between alcohol use and ART non-adherence or viral non-suppression. We defined ART non-adherence using the definitions from each parent study (e.g., patients with > 5% missed ART doses during the previous four, seven or 30 days were considered non-adherent). A random effects meta-analysis was conducted to pool associations and we conducted additional analyses to assess between-study heterogeneity and publication bias and sensitivity analyses to determine robustness of our results when considering only certain study designs, alcohol use or ART scales, or studies that used viral non-suppression as their primary outcome. Of 56 articles meeting our inclusion criteria, 32 articles were included in the meta-analysis. All studies measured alcohol use via self-report. ART non-adherence was assessed using self-report, pill counts, or pharmacy records and definition of non-adherence varied depending on the measure used. Individuals who used alcohol had twice the odds of ART non-adherence compared with those who did not use alcohol (34% non-adherence among alcohol users vs. 18% among non-users; pooled odds ratio: 2.25; 95% confidence interval: 1.87-2.69; p < 0.001). We found evidence of a high degree of heterogeneity between studies (Cochrane Q statistic: 382.84, p< 0.001; I2 proportion: 91.9%) and evidence of publication bias. However, the magnitude of our pooled odds ratio was consistent across a number of sensitivity analyses to account for heterogeneity and publication bias. In a secondary analysis with studies using viral non-suppression as their primary outcome, we also estimated a statistically significant pooled effect of alcohol use on viral non-suppression (pooled odds ratio: 2.47; 95% confidence interval: 1.58-3.87). Evidence suggests alcohol use is associated with ART non-adherence in Sub-Saharan Africa, potentially hindering achievement of the UNAIDS 90-90-90 HIV treatment targets.

Implementation science and stigma reduction interventions in low- and middle-income countries: a systematic review.

BACKGROUND: Interventions to alleviate stigma are demonstrating effectiveness across a range of conditions, though few move beyond the pilot phase, especially in low- and middle-income countries (LMICs). Implementation science offers tools to study complex interventions, understand barriers to implementation, and generate evidence of affordability, scalability, and sustainability. Such evidence could be used to convince policy-makers and donors to invest in implementation. However, the utility of implementation research depends on its rigor and replicability. Our objectives were to systematically review implementation studies of health-related stigma reduction interventions in LMICs and critically assess the reporting of implementation outcomes and intervention descriptions. METHODS: PubMed, CINAHL, PsycINFO, and EMBASE were searched for evaluations of stigma reduction interventions in LMICs reporting at least one implementation outcome. Study- and intervention-level characteristics were abstracted. The quality of reporting of implementation outcomes was assessed using a five-item rubric, and the comprehensiveness of intervention description and specification was assessed using the 12-item Template for Intervention Description and Replication (TIDieR). RESULTS: A total of 35 eligible studies published between 2003 and 2017 were identified; of these, 20 (57%) used qualitative methods, 32 (91%) were type 1 hybrid effectiveness-implementation studies, and 29 (83%) were evaluations of once-off or pilot implementations. No studies adopted a formal theoretical framework for implementation research. Acceptability (20, 57%) and feasibility (14, 40%) were the most frequently reported implementation outcomes. The quality of reporting of implementation outcomes was low. The 35 studies evaluated 29 different interventions, of which 18 (62%) were implemented across sub-Saharan Africa, 20 (69%) focused on stigma related to HIV/AIDS, and 28 (97%) used information or education to reduce stigma. Intervention specification and description was uneven. CONCLUSION: Implementation science could support the dissemination of stigma reduction interventions in LMICs, though usage to date has been limited. Theoretical frameworks and validated measures have not been used, key implementation outcomes like cost and sustainability have rarely been assessed, and intervention processes have not been presented in detail. Adapted frameworks, new measures, and increased LMIC-based implementation research capacity could promote the rigor of future stigma implementation research, helping the field deliver on the promise of stigma reduction interventions worldwide.

Associations Between Anxiety and Adherence to Antiretroviral Medications in Low- and Middle-Income Countries: A Systematic Review and Meta-analysis.

Untreated mental health disorders among people living with HIV (PLHIV) may prevent low- and middle-income countries (LMICs) from achieving the UNAIDS 90-90-90 targets. Anxiety disorders may be associated with decreased adherence to antiretroviral therapy (ART). We sought to review and meta-analyze studies estimating associations between anxiety and ART adherence in LMICs. We searched PubMed, PsychINFO, CINAHL and EMBASE for relevant studies published before July 18, 2018. We defined anxiety as reported anxiety scores from screening questionnaires or having a clinical diagnosis of an anxiety disorder, and poor ART adherence as missed doses, poor visit attendance, or scores from structured adherence questionnaires. We used a random effects model to conduct a meta-analysis for calculating a pooled odds ratio, and conducted sensitivity analyses by time on ART, anxiety evaluation method, and study region. From 472 screened manuscripts, thirteen studies met our inclusion criteria. Eleven studies were included in the meta-analysis. PLHIV who reported anxiety had 59% higher odds of poor ART adherence compared with those who did not report anxiety disorder (pooled odds ratio [pOR]: 1.59, 95% confidence interval [CI] 1.29-1.96, p < 0.001). When excluding PLHIV who initiated ART within 6 months, reported anxiety remained strongly associated with poor ART adherence (pOR: 1.61, 95% CI 1.18-2.20, p = 0.003). Among PLHIV in LMICs, reported anxiety was associated with poor ART adherence. This association persisted after the ART initiation period. Increased resources for mental health may be important for achieving virologic suppression in LMICs.

Moderating Factors in an Anti-stigma Intervention for African American Women with HIV in the United States: A Secondary Analysis of the UNITY Trial.

African American women experience higher rates of HIV than other women in the United States, and stigma has been identified as an important determinant of engagement in HIV care. Our study examined whether key variables moderated the effect of an anti-stigma intervention on outcomes among African American women receiving treatment for HIV. Twelve potential moderators included: age, years lived with HIV, marital status, employment status, education level, PTSD diagnosis, alcohol use, social support, baseline CD4 count, baseline viral load, and number of children. Outcomes included changes in: HIV-related stigma, social support, depressive symptoms, PTSD symptoms, alcohol use, viral load, and engagement in HIV care. Results suggest that the intervention is associated with greater improvement in engagement in care among participants with PTSD or depression at baseline, and may help maintain engagement in care among participants experiencing certain mental health conditions. This provides opportunities to address discriminatory structural barriers that lead to stigma and drop-offs in HIV care.

HIV-Related Stigma and Viral Suppression Among African-American Women: Exploring the Mediating Roles of Depression and ART Nonadherence.

We used baseline data from a sample of African-American women living with HIV who were recruited to participate in a stigma-reduction intervention in Chicago and Birmingham (2013-2015) to (1) evaluate the relationship between HIV-related stigma and viral suppression, and (2) assess the role of depression and nonadherence to antiretroviral therapy (ART) as mediators. Data from women were included in this secondary analysis if they were on ART, had viral load data collected within 8-weeks of study entry and had complete covariate data. We used logistic regression to estimate the total effect of HIV-related stigma (14-item Stigma Scale for Chronic Illness) on viral suppression (< 200 copies/mL), and serial mediation analysis to estimate indirect effects mediated by depressive symptoms (8-item Patient Health Questionnaire) and ART nonadherence (number of days with missed doses). Among 100 women who met study inclusion criteria, 95% reported some level of HIV-related stigma. In adjusted models, higher levels of HIV-related stigma were associated with lower odds of being virally suppressed (AOR = 0.93, 95% CI = 0.89-0.98). In mediation analysis, indirect effects through depression and ART nonadherence were not significant. Findings suggest that HIV-related stigma is common among African-American women living with HIV, and those who experience higher levels of stigma are less likely to be virally suppressed. However, the mechanisms remain unclear.

Implementation of eHealth Interventions Across the HIV Care Cascade: a Review of Recent Research.

PURPOSE OF REVIEW: We review recent implementation science focusing on eHealth interventions to improve outcomes along the HIV care cascade. We highlight several gaps in the eHealth implementation literature and propose areas for future study. RECENT FINDINGS: We identified 17 studies conducted in North America, Europe, and sub-Saharan Africa assessing the acceptability, appropriateness, adoption, cost, feasibility, fidelity, penetration, or sustainability of eHealth interventions targeting the HIV care cascade. Most interventions used SMS messages to improve cascade outcomes. Feasibility research has demonstrated the importance of adaptability for intervention scale-up and delivery. Key gaps in the literature remain related to predictors of the adoption of eHealth interventions by health facilities and staff. In addition, no studies explored sustainability and few used theoretical frameworks for implementation research or validated measures of implementation outcomes. We propose next steps for the future of eHealth implementation research to inform the delivery, scale-up, and maintenance of eHealth interventions in the real world.

Process and impact evaluation of a community gender equality intervention with young men in Rajasthan, India.

This paper reports on the results of a process and impact evaluation to assess the effects of a project aiming to engage men in changing gender stereotypes and improving health outcomes for women in villages in Rajasthan, India. We conducted seven focus group discussions with participants in the programme and six in-depth interviews with intervention group leaders. We also conducted 137 pre- and 70 post-intervention surveys to assess participant and community knowledge, attitudes and behaviours surrounding gender, violence and sexuality. We used thematic analysis to identify process and impact themes, and hierarchical mixed linear regression for the primary outcome analysis of survey responses. Post-intervention, significant changes in knowledge and attitudes regarding gender, sexuality and violence were made on the individual level by participants, as well as in the community. Moderate behavioural changes were seen in individuals and in the community. Study findings offer a strong model for prevention programmes working with young men to create a community effect in encouraging gender equality in social norms.

Pre/post evaluation of a pilot prevention with positives training program for healthcare providers in North West Province, Republic of South Africa.

BACKGROUND: Prevention interventions for people living with HIV/AIDS are an important component of HIV programs. We report the results of a pilot evaluation of a four-hour, clinic-based training for healthcare providers in South Africa on HIV prevention assessments and messages. This pre/post pilot evaluation examined whether the training was associated with providers delivering more prevention messages. METHODS: Seventy providers were trained at four public primary care clinics with a high volume of HIV patients. Pre- and post-training patient exit surveys were conducted using Audio-Computer Assisted Structured Interviews. Seven provider appropriate messaging outcomes and one summary provider outcome were compared pre- and post-training using Poisson regression. RESULTS: Four hundred fifty-nine patients pre-training and 405 post-training with known HIV status were interviewed, including 175 and 176 HIV positive patients respectively. Among HIV positive patients, delivery of all appropriate messages by providers declined post-training. The summary outcome decreased from 56 to 50%; adjusted rate ratio 0.92 (95% CI = 0.87-0.97). Sensitivity analyses adjusting for training coverage and time since training detected fewer declines. Among HIV negative patients the summary score was stable at 32% pre- and post-training; adjusted rate ratio 1.05 (95% CI = 0.98-1.12). CONCLUSIONS: Surprisingly, this training was associated with a decrease in prevention messages delivered to HIV positive patients by providers. Limited training coverage and delays between training and post-training survey may partially account for this apparent decrease. A more targeted approach to prevention messages may be more effective.

A mixed methods analysis of youth mental health intervention feasibility and acceptability in a North American city: Perspectives from Seattle, Washington.

In March 2021, the Governor of Washington declared a youth mental health crisis. State data revealed high rates of youth suicide and inadequate access to services. This study aims to ascertain the kinds of support across the mental health care continuum recommended by young people and key stakeholders who could assist with implementation in Seattle. We interviewed 15 key informants to identify the contextual, structural, and individual-level factors that increase the risk of poor mental health and deter access to care among youth. We complimented these data with a 25-item survey of 117 participants in King County to assess the feasibility and acceptability of interventions for youth mental health. We conducted a deductive thematic qualitative analysis of the interviews and performed descriptive analyses of the quantitative data, using t-tests and χ2 tests to summarize and compare participant characteristics stratified by age group. Qualitative informants attributed challenges to youth mental health to social isolation and relational problems. Example interventions included creating environments that increase belonging and implementation of culturally congruent mental health services. Quantitative study participants rated all evidence-based mental health interventions presented as highly acceptable. However, youth preferred interventions promoting social connectedness, peer support, and holistic approaches to care, while non-youth preferred interventions focused on suicide, and substance abuse prevention. Key informants and survey participants identified schools as the most important setting for mental health interventions. There were no significant differences among quantitative outcomes. Our findings highlight the need for interventions that reduce isolation and increase social connectedness to support youth mental health. As the city designs youth responsive interventions, schools and digital platforms should be prioritized. Engaging multiple stakeholders, particularly young people, tackling cultural stigma surrounding mental health, and improving access to safe community spaces are important considerations for youth mental health interventions.

Implementation strategies to improve HIV care cascade outcomes in low- and middle-income countries: a systematic review from 2014 to 2021.

INTRODUCTION: In low- and middle-income countries (LMICs), which are disproportionately affected by the HIV epidemic and manage limited resources, optimized implementation strategies are needed to enhance the efficiency of the HIV response. Assessing strategy usage to date could identify research gaps and inform future implementation efforts. We conducted a systematic review to describe the features and distributions of published implementation strategies attempting to improve HIV treatment service delivery and outcomes. METHODS: We searched PubMed, Embase, and CINAHL and screened abstracts and full texts published between 1 January 2014 and 27 August 2021, for English-language studies conducted in LMICs that described the implementation of HIV intervention and reported at least one HIV care cascade outcome, ranging from HIV testing to viral suppression. Implementation strategies were inductively specified, characterized by unique combinations of actor, action and action target, and summarized based on existing implementation strategy taxonomies. All strategies included in this study were independently reviewed to ensure accuracy and consistency. RESULTS: We identified 44,126 abstracts and reviewed 1504 full-text manuscripts. Among 485 included studies, 83% were conducted in sub-Saharan Africa; the rest were conducted in South-East Asia and Western Pacific (12%), and the Americas (8%). A total of 7253 unique implementation strategies were identified, including changing health service delivery (48%) and providing capacity building and support strategies (34%). Healthcare providers and researchers led 59% and 28% of the strategies, respectively. People living with HIV and their communities (62%) and healthcare providers (38%) were common strategy targets. Strategies attempting to change governance, financial arrangements and implementation processes were rarely reported. DISCUSSION: We identified a range of published implementation strategies that addressed HIV cascade outcomes, though some key gaps exist. We may need to expand the application of implementation strategies to ensure that all stakeholders are meaningfully involved to support equitable implementation efforts across the geographic regions and target populations, and to optimize implementation outcomes. CONCLUSIONS: Some health service delivery and capacity building and support strategies have been most commonly used to date. Future research and implementation may incorporate a more diverse range of strategies and detailed reporting on their usage to inform improved HIV responses globally.

Cumulative exposure to depressive symptoms and all-cause mortality among adults with HIV in Kenya, Nigeria, Tanzania, and Uganda.

OBJECTIVE: We estimated the effects of cumulative exposure to depressive symptoms on risk of all-cause mortality among people with HIV (PWH) in four African countries. DESIGN: An analysis of prospective cohort data. METHODS: The African Cohort Study (AFRICOS) is a prospective cohort of people receiving care at twelve clinics in Kenya, Nigeria, Tanzania, and Uganda. Every 6 months from January 2013 to May 2020, participants underwent laboratory monitoring, structured surveys, and assessment of depressive symptom severity using the Center for Epidemiologic Studies Depression Scale (CES-D). All-cause mortality was the outcome of interest. The predictor of interest was a time-updated measure of the percentage of days lived with depression (PDD). Marginal structural Cox proportional hazards regression models were used, adjusting for potential confounders including time-varying alcohol use, drug use, and viral load. RESULTS: Among 2520 enrolled participants, 1479 (59%) were women and the median age was 38 (interquartile range [IQR]: 32-46). At enrollment, 1438 (57%) were virally suppressed (<200 copies/ml) and 457 (18%) had CES-D at least 16, indicating possible depression. Across 9093 observed person-years, the median PDD was 0.7% (IQR: 0-5.9%) with 0.8 deaths per 100 person-years. Leading causes of death included cancer (18% of deaths) and accidents (14%). Models suggested that each 25% absolute increase in PDD was associated with a 69% increase in the risk of all-cause mortality (hazard ratio: 1.69; 95% confidence interval: 1.18-2.43). CONCLUSION: Cumulative exposure to depressive symptoms was substantially associated with the risk of mortality in this cohort of PWH in Africa.

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.

COVID-19, the COVID-19 response, and racial injustice: Associations with depressive and anxiety symptoms among US adults from April 2020 to March 2021.

Background: People in the United States have faced numerous large and intersecting threats to their mental health since the onset of the coronavirus disease pandemic. This study aimed to understand the unique relationships between these co-occurring threats - including the police killings of unarmed Black people and the fight for racial justice - and how they affect mental health symptoms among various demographic groups. Methods: Data on population mental health, state-level COVID-19 incidence rates, cases of police-involved killings, and occurrences of racial justice protests were analyzed. The primary outcome was depression or anxiety symptoms. Regression models were used to estimate prospective associations between individual-, household-, and state-level exposures to hypothesized mental health threats and subsequent depression or anxiety symptoms. Results: Data from 2,085,041 individual participants were included. Most were women (51.2%), and most were white, non-Hispanic (61.2%), with almost half (47.7%) reporting some loss of household income since March 13, 2020. Neither the killing of unarmed Black people by police, nor the above-average occurrence of Black Lives Matter (BLM) protests, were observed to be associated with anxiety or depressive symptoms in the overall population, though the BLM protests were associated with reduced depressive and anxiety symptoms among younger participants. State-level COVID-19 incidence risk was more strongly associated with depressive and anxiety symptoms among women, Black people, older people, and higher income people, compared to men, white people, younger people, and lower income people. Conclusion: Our findings are relevant for anticipating and addressing the mental health consequences of social injustice and protest movements in the context of COVID-19 pandemic, as well as future pandemics. Promoting population mental health requires addressing underlying social and structural inequities and prioritizing the pursuit of social justice and health equity as a primary mental health intervention.

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. TRIAL REGISTRATION: PROSPERO, CRD42021268374.

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.

Estimating additional schooling and lifetime earning obtained from improved linear growth in low- and middle-income countries using the Lives Saved Tool (LiST).

Background: Policymakers seeking to prioritize the use of restricted financial resources need to understand the relative costs and benefits of interventions for improving nutritional status. Improved linear growth can lead to increased education attainment and improved economic productivity in low- and middle-income countries (LMICs), though these non-health-related benefits are not reflected in current long-term modelling efforts, including the Lives Saved Tool (LiST). Our objective was to integrate the effects of improved linear growth on non-health related benefit into LiST by estimating subsequent gains in years of schooling and wage earnings. We then estimated the impacts of reaching the Sustainable Development Goals (SDGs) target for stunting in South Asian countries on lifetime productivity. Methods: In the first step, we used LiST outputs to estimate the improved linear growth due to scaled-up nutrition interventions and used published estimates to quantify the education gain resulting from an increase in height for age z-score (HAZ). In the second step, we used published country-level estimates on economic returns to schooling to quantify the relative gains in wages that children born today will experience because of their additional education attainment in the future. In the last step, we used country-level data on wages to estimate the net present value of future earnings gained due to early childhood growth improvement per birth cohort. Results: If South Asia countries reach the SDG target by 2025, an estimated 8.6 million years of schooling will be obtained by six birth cohorts of 2020 to 2025. These six birth cohorts will also gain an estimated US$64 893 million in the present value term, at a 5% discount rate, in lifetime earnings. India has the largest expected gain in years of schooling (7367 years) and lifetime earnings (US$59 390 million in present value terms, at a 5% discount rate). Conclusions: Two non-health-related benefits of improved linear growth - additional years of schooling and lifetime earnings - are added in LiST. Together with LiST costing, users can now conduct both cost-effective and benefit-cost analyses. Using both analyses will provide more comprehensive insights into nutrition interventions' relative costs and benefits.
