Identification of the needs and priorities of older people and stakeholders in rural and urban areas of Santo Andre, Brazil.

BACKGROUND: There are few data reporting the needs and priorities of older adults in Brazil. This hampers the development and/or implementation of policies aimed at older adults to help them age well. The aim of this study was to understand areas of importance, priorities, enablers and obstacles to healthy ageing as identified by older adults and key stakeholders in both urban and rural environments. METHODS: Two locations were selected, one urban and one rural in the municipality of Santo André, in the metropolitan region of São Paulo (SP). Workshops for older adults (>60 y) and stakeholders were conducted separately in each location. The workshops incorporated an iterative process of discussion, prioritisation and ranking of responses, in roundtable groups and in plenary. Areas of commonality and differences between older adult and stakeholder responses were identified by comparing responses between groups as well as mapping obstacles and enablers to healthy ageing identified by older adults, to the priorities identified by stakeholder groups. The socio-ecologic model was used to categorise responses. RESULTS: There were few shared responses between stakeholders and older adults and little overlap between the top ranked responses of urban and rural groups. With respect to areas of importance, both stakeholder groups ranked policies for older people within their top five reponses. Both older adult groups ranked keeping physically and mentally active, and nurturing spirituality. There was a marked lack of congruence between older adults' obstacles and enablers to healthy ageing and stakeholder priorities, in both urban and rural settings. Most responses were located within the Society domain of the socio-ecologic model, although older adults also responded within the Individual/ Relationships domains, particularly in ranking areas of most importance for healthy ageing. CONCLUSIONS: Our results highlight substantial differences between older adults and stakeholders with respect to areas of importance, priorities, enablers and obstacles to healthy ageing, and point to the need for more engagement between those in advocacy and policymaking roles and the older people whose needs they serve.

Utilization of at-home tests for coronavirus disease 2019 (COVID-19) among healthcare workers in Chicago.

Objective: To describe utilization of at-home coronavirus disease 2019 (COVID-19) testing among healthcare workers (HCW). Design: Serial cross-sectional study. Setting and participants: HCWs in the Chicago area. Methods: Serial surveys were conducted from the Northwestern Medicine (NM HCW SARS-CoV-2) Serology Cohort Study. In April 2022, participants reflected on the past 30 days to complete an online survey regarding COVID-19 home testing. Surveys were repeated in June and November 2022. The percentage of completed home tests and ever-positive tests were reported. Multivariable Poisson regression was used to calculate prevalence rate ratios (PRR) and univariate analysis was used for association between participant characteristics with home testing and positivity. Results: Overall, 2,226 (62.4%) of 3,569 responded to the survey in April. Home testing was reported by 26.6% of respondents and 5.9% reported having at least one positive home test. Testing was highest among those 30-39 years old (35.9%) and nurses (28.3%). A positive test was associated (P < .001) with exposure to people, other than patients with known or suspected COVID-19. Home testing increased in June to 36.4% (positivity 19.9%) and decreased to 25% (positivity 13.5%) by November. Conclusion: Our cohort findings show the overall increase in both home testing and ever positivity from April to November - a period where changes in variants of concern of SARS-CoV-2 were reported nationwide. Having an exposure to people, other than patients with known or suspected COVID-19 was significantly associated with both, higher home testing frequency and ever-test positivity.

Implementation of a clinically integrated breastfeeding peer counselor program.

OBJECTIVE: Reflecting disparities across the US, in 2015 publicly insured patients of the NorthShore Community Health Center (NSCHC) in Evanston, Illinois had lower breastfeeding rates than commercially insured patients. We used the Replicating Effective Programs framework to describe the design and implementation of a clinically-integrated breastfeeding peer counseling (ci-BPC) program to address these disparities. STUDY DESIGN: Patient focus groups and surveys informed program design, and a multidisciplinary clinical support team developed workflows that integrated the breastfeeding peer counselor (BPC) into the clinic and the postpartum unit. RESULTS: ci-BPC improved breastfeeding intensity and duration by providing every NSCHC patient with (1) prenatal lactation education; (2) hands on lactation care in the hospital; and (3) on-demand postpartum support. Total cost per patient was $297-386. The program was sustained after demonstrating potential cost-savings. CONCLUSION: An evidence-based, multidisciplinary collaboration resulted in a sustainable clinically integrated breastfeeding peer counseling program that improved breastfeeding outcomes.

Priorities and barriers for ageing well; results from stakeholder workshops in rural and urban Rwanda.

BACKGROUND: The National Older Person's Policy of 2021 in Rwanda highlights the need for social protection of older populations. However, there is a lack of local knowledge regarding the priorities and challenges to healthy aging faced by older people and their caregivers. OBJECTIVES: This study aimed to identify and compare the needs and priorities of older people and other stakeholders involved in caring for them in rural and urban areas of Rwanda. METHODS: The study was conducted in two locations, Kigali (urban) and Burera district (rural). Each site hosted two separate one-day workshops with older people (≥60 years) and stakeholders (all ages). Discussions were held in plenary and roundtable-groups to generate a list of the top 4 prioritized responses on areas of importance, priorities/enablers to be addressed, and obstacles to living a healthy and active life for older people. The research team identified similarities between stakeholder and older people's responses in each area and a socio-ecological model was used to categorize findings. RESULTS: There were substantial differences in responses between rural and urban areas and between older people and stakeholders. For each question posed, in each rural or urban area, there was only agreement between stakeholders and older people for a maximum of one response. Whereas, when comparing responses from the same participant groups in urban or rural settings, there was a maximum agreement of two responses, with two questions having no agreement in responses at all. Responses across all discussion-areas were mostly categorized within the Societal level, with Individual, Relationship, and Environment featuring less frequently. CONCLUSION: This study highlights the need for contextually curated interventions to address the concerns of older adults and their caregivers in rural and urban settings. An inclusive and multidimensional approach is needed to conquer the barriers that impede healthy aging, with input from various stakeholders.

Evaluation of Primary Healthcare Centers' Service Availability and Readiness for Implementing Diabetes Care in Abuja, Nigeria: A Cross-Sectional, Formative Assessment.

Introduction: Noncommunicable diseases (NCDs) are associated with a high and rising burden of morbidity and mortality in sub-Saharan Africa, including Nigeria. Diabetes mellitus (DM) is among the leading causes of NCD-related deaths worldwide and is a foremost public health problem in Nigeria. As part of the National Multi-Sectoral Action Plan for the Prevention and Control of NCDs, Nigeria has committed to implementing the World Health Organization (WHO) Package of Essential NCD control interventions. Implementing the intervention requires the availability of essential elements, including guidelines, trained staff, health management information systems, equipment, and medications, in primary healthcare centers (PHCs). This study assessed the availability of the WHO package components and the readiness of PHCs to implement a DM screening, evaluation, and management program. Methods: This cross-sectional formative assessment adapted the WHO Service Availability and Readiness Assessment (SARA) tool to survey 30 PHCs selected by multistage sampling for readiness to deliver DM diagnosis and care in Abuja, Nigeria, between August 2021 and October 2021. The service availability and readiness indicator scores were calculated based on the proportion of PHCs with available DM care services, minimum staff requirement, diagnostic tests, equipment, medications, and national guidelines/protocols for DM care within the defined SARA domain. Results: All 30 PHCs reported the availability of at least two full-time staff (median [interquartile range] staff = 5 [4-9]), which were mostly community health extension workers (median [interquartile range]) = 3 [1-4]. At least one staff member was recently trained in DM care in only 11 (36%) of the PHCs. The study also reported high availability (100%) of paper-based health management information systems (HMIS) and DM screening services using a glucometer (87%), but low availability of DM treatment (23%), printed job aids (27%), and national guidelines/protocols (0%). Conclusion: This systematic assessment of PHCs' readiness to implement a DM screening, evaluation, and management program in Abuja demonstrated readiness to integrate DM care into PHCs in terms of equipment, paper-based HMIS, and nonphysician health workers' availability. However, strategies are needed to promote DM health workforce training, provide DM management guidelines, and ensure a reliable supply of essential DM medications.

Prevalence and Risk Factors for Renal Insufficiency among Adults Living with HIV in Tanzania: Results from a Cross-Sectional Study in 2020-2021.

With improved survival, adults living with HIV (ALHIV) are increasingly likely to experience age-related and HIV-related comorbidities, including renal insufficiency. Other risk factors for renal insufficiency (high blood pressure (BP), obesity, diabetes, and dyslipidemia) are also growing more common among ALHIV. To determine the prevalence of renal insufficiency (defined as an eGFR < 60 mL/min/1.73 m2) and factors associated with reduced eGFR, we conducted a cross-sectional study at six HIV clinics in Dar-es-Salaam, Tanzania. We applied multivariable (MV) ordinal logistic regression models to identify factors associated with reduced eGFR and examined the interaction of age with BP levels. Among the 450 ALHIV on ART analyzed [26% males; median age 43 (IQR: 18-72) years; 89% on tenofovir-containing ART; 88% HIV viral load ≤50 copies/mL], 34 (7.5%) had renal insufficiency. Prevalence was higher among males (12%) vs. females (6%), p = 0.03; ALHIV ≥50 (21%) vs. <50 years (2.5%), p < 0.001; those with high [≥130/80 mmHg (15%)] vs. normal [<120/80 mmHg (4%)] BP, p < 0.01 and those with dyslipidemia (10%) vs. those without (4.5%), p < 0.03. After adjusting for covariates, age (in years) was the only covariate with a statistically significant association with reduced eGFR (OR = 1.09 (1.07-1.12), p < 0.001). No significant interaction between age and BP was found. Interventions to increase routine screening for renal insufficiency, especially among older ALHIV, and improve BP control are critical to reducing kidney disease-related morbidity and mortality.

Optimizing integration of community-based management of possible serious bacterial infection (PSBI) in young infants into primary healthcare systems in Ethiopia and Kenya: successes and challenges.

BACKGROUND: Ethiopia and Kenya have adopted the community-based integrated community case management (iCCM) of common childhood illnesses and newborn care strategy to improve access to treatment of infections in newborns and young infants since 2012 and 2018, respectively. However, the iCCM strategy implementation has not been fully integrated into the health system in both countries. This paper describes the extent of integration of iCCM program at the district/county health system level, related barriers to optimal integration and implementation of strategies. METHODS: From November 2020 to August 2021, Ethiopia and Kenya implemented the community-based treatment of possible serious bacterial infection (PSBI) when referral to a higher facility is not possible using embedded implementation research (eIR) to mitigate the impact of COVID-19 on the delivery of this life-saving intervention. Both projects conducted mixed methods research from April-May 2021 to identify barriers and facilitators and inform strategies and summative evaluations from June-July 2022 to monitor the effectiveness of implementation outcomes including integration of strategies. RESULTS: Strategies identified as needed for successful implementation and sustainability of the management of PSBI integrated at the primary care level included continued coaching and support systems for frontline health workers, technical oversight from the district/county health system, and ensuring adequate supply of commodities. As a result, support and technical oversight capacity and collaborative learning were strengthened between primary care facilities and community health workers, resulting in improved bidirectional linkages. Improvement of PSBI treatment was seen with over 85% and 81% of estimated sick young infants identified and treated in Ethiopia and Kenya, respectively. However, perceived low quality of service, lack of community trust, and shortage of supplies remained barriers impeding optimal PSBI services access and delivery. CONCLUSION: Pragmatic eIR identified shared and unique contextual challenges between and across the two countries which informed the design and implementation of strategies to optimize the integration of PSBI management into the health system during the COVID-19 pandemic. The eIR participatory design also strengthened ownership to operationalize the implementation of identified strategies needed to improve the health system's capacity for PSBI treatment.

Establishing Evidence Criteria for Implementation Strategies: A Delphi Study for HIV Services.

Background: There are no criteria specifically for evaluating the quality of implementation research and recommend implementation strategies likely to have impact to practitioners. We describe the development and application of the Best Practices Rubric, a set of criteria to evaluate the evidence supporting implementation strategies, in the context of HIV. Methods: We developed the Best Practices Rubric from 2022-2023 in three phases. (1) We purposively selected and recruited by email participants representing a mix of expertise in HIV service delivery, quality improvement, and implementation science. We developed a draft rubric and criteria based on a literature review and key informant interviews. (2) The rubric was then informed and revised through two e-Delphi rounds using a survey delivered online through Qualtrics. The first and second round Delphi surveys consisted of 71 and 52 open and close-ended questions, respectively, asking participants to evaluate, confirm, and make suggestions on different aspects of the rubric. After each survey round, data were analyzed and synthesized as appropriate, and the rubric and criteria were revised. (3) We then applied the rubric to a set of research studies assessing 18 implementation strategies designed to promote the adoption and uptake of pre-exposure prophylaxis, an HIV prevention medication, to assess reliable application of the rubric and criteria. Results: Our initial literature review yielded existing rubrics and criteria for evaluating intervention-level evidence. For a strategy-level rubric, additions emerged from interviews, for example, a need to consider the context and specification of strategies. Revisions were made after both Delphi rounds resulting in the confirmation of five evaluation domains - research design, implementation outcomes, limitations and rigor, strategy specification, and equity - and four evidence levels - best practice, promising practice, more evidence needed, and harmful practices. For most domains, criteria were specified at each evidence level. After an initial pilot round to develop an application process and provide training, we achieved 98% reliability when applying the criteria to 18 implementation strategies. Conclusions: We developed a rubric to evaluate the evidence supporting implementation strategies for HIV services. Although the rubric is specific to HIV, this tool is adaptable for evaluating strategies in other health areas.

Effect of community-based newborn care implementation strategies on access to and effective coverage of possible serious bacterial infection (PSBI) treatment for sick young infants during COVID-19 pandemic.

BACKGROUND: In Ethiopia, neonatal mortality is persistently high. The country has been implementing community-based treatment of possible serious bacterial infection (PSBI) in young infants when referral to a hospital is not feasible since 2012. However, access to and quality of PSBI services remained low and were worsened by COVID-19. From November 2020 to June 2022, we conducted implementation research to mitigate the impact of COVID-19 and improve PSBI management implementation uptake and delivery in two woredas in Ethiopia. METHODS: In April-May 2021, guided by implementation research frameworks, we conducted formative research to understand the PSBI management implementation challenges, including those due to the COVID-19 pandemic. Through a participatory process engaging stakeholders, we designed adaptive implementation strategies to bridge identified gaps using mechanism mapping to achieve implementation outcomes. Strategies included training and coaching, supportive supervision and mentorship, technical support units, improved supply of essential commodities, and community awareness creation about PSBI and COVID-19. We conducted cross-sectional household surveys in the two woredas before (April 2021) and after the implementation of strategies (June 2022) to measure changes in targeted outcomes. RESULTS: We interviewed 4,262 and 4,082 women who gave live birth 2-14 months before data collection and identified 374 and 264 PSBI cases in April 2021 and June 2022, respectively. The prevalence of PSBI significantly decreased (p-value = 0.018) from 8.7% in April 2021 to 6.4% while the mothers' care-seeking behavior from medical care for their sick newborns increased significantly from 56% to 91% (p-value <0.01). Effective coverage of severely ill young infants that took appropriate antibiotics significantly improved from 33% [95% CI: 25.5-40.7] to 62% [95% CI: 51.0-71.6]. Despite improvements in the uptake of PSBI treatment, persisting challenges at the facility and systems levels impeded optimal PSBI service delivery and uptake, including perceived low quality of service, lack of community trust, and shortage of supplies. CONCLUSION: The participatory design and implementation of adaptive COVID-19 strategies effectively improved the uptake and delivery of PSBI treatment. Support systems were critical for frontline health workers to deliver PSBI services and create a resilient community health system to provide quality PSBI care during the pandemic. Additional strategies are needed to address persistent gaps, including improvement in client-provider interactions, supply of essential drugs, and increased social mobilization strategies targeting families and communities to further increase uptake.

Barriers and facilitators to the delivery of age-friendly health services in Primary Health Care centres in southwest, Nigeria: A qualitative study.

BACKGROUND: With the rapid growth of Nigeria's older population, it has become important to establish age-friendly healthcare systems that support care for older people. This study aimed to explore the barriers and facilitators to the delivery of age-friendly health services from the perspectives of primary healthcare managers in Lagos State, Nigeria. METHOD: We conducted 13 key informant interviews including medical officers of health, principal officers of the (Primary Health Care) PHC Board and board members at the state level. Using a grounded theory approach, qualitative data analysis was initially done by rapid thematic analysis followed by constant comparative analysis using Dedoose software to create a codebook. Three teams of two coders each blind-coded the interviews, resolved coding discrepancies, and reviewed excerpts by code to extract themes. RESULTS: The main barriers to the delivery of age-friendly services included the lack of recognition of older adults as a priority population group; absence of PHC policies targeted to serve older adults specifically; limited training in care of older adults; lack of dedicated funding for care services for older adults and data disaggregated by age to drive decision-making. Key facilitators included an acknowledged mission of the PHCs to provide services for all ages; opportunities for the enhancement of older adult care; availability of a new building template that supports facility design which is more age-friendly; access to basic health care funds; and a positive attitude towards capacity building for existing workforce. CONCLUSION: While we identified a number of challenges, these offer opportunities to strengthen and prioritize services for older adults in PHCs and build on existing facilitators. Work is needed to identify and test interventions to overcome these challenges and improve the responsiveness of the PHC system to older adults through the delivery of age-friendly health services in PHCs in Lagos, Nigeria.

Mitigating the impact of COVID-19 on primary healthcare interventions for the reduction of under-5 mortality in Bangladesh: Lessons learned through implementation research.

The COVID-19 pandemic posed unprecedented challenges and threats to health systems, particularly affecting delivery of evidence-based interventions (EBIs) to reduce under-5 mortality (U5M) in resource-limited settings such as Bangladesh. We explored the level of disruption of these EBIs, strategies and contextual factors associated with preventing or mitigating service disruptions, and how previous efforts supported the work to maintain EBIs during the pandemic. We utilized a mixed methods implementation science approach, with data from: 1) desk review of available literature; 2) existing District Health Information System 2 (DHIS2) in Bangladesh; and 3) key informant interviews (KIIs), exploring evidence on changes in coverage, implementation strategies, and contextual factors influencing primary healthcare EBI coverage during March-December 2020. We used interrupted time series analysis (timeframe January 2019 to December 2020) using a Poisson regression model to estimate the impact of COVID-19 on DHIS2 indicators. We audio recorded, transcribed, and translated the qualitative data from KIIs. We used thematic analysis of coded interviews to identify emerging patterns and themes using the implementation research framework. Bangladesh had an initial drop in U5M-oriented EBIs during the early phase of the pandemic, which began recovering in June 2020. Barriers such as lockdown and movement restrictions, difficulties accessing medical care, and redirection of the health system's focus to the COVID-19 pandemic, resulted in reduced health-seeking behavior and service utilization. Strategies to prevent and respond to disruptions included data use for decision-making, use of digital platforms, and leveraging community-based healthcare delivery. Transferable lessons included collaboration and coordination of activities and community and civil society engagement, and investing in health system quality. Countries working to increase EBI implementation can learn from the barriers, strategies, and transferable lessons identified in this work in an effort to reduce and respond to health system disruptions in anticipation of future health system shocks.

Under-five mortality before and after implementation of the Liberia National Community Health Assistant (NCHA) program: A study protocol.

Between 2018 and 2022 the Liberian Government implemented the National Community Health Assistant (NCHA) program to improve provision of maternal and child health care to underserved rural areas of the country. Whereas the contributions of this and similar community health worker (CHW) based healthcare programs have been associated with improved process measures, the impact of a governmental CHW program at scale on child mortality has not been fully established. We will conduct a cluster sampled, community-based survey with landmark event calendars to retrospectively assess child births and deaths among all children born to women in the Grand Bassa District of Liberia. We will use a mixed effects Cox proportional hazards model, taking advantage of the staggered program implementation in Grand Bassa districts over a period of 4 years to compare rates of under-5 child mortality between the pre- and post-NCHA program implementation periods. This study will be the first to estimate the impact of the Liberian NCHA program on under-5 mortality.

Interventions and contextual factors to improve retention in care for patients with hypertension in primary care: Hermeneutic systematic review.

BACKGROUND: Regular engagement over time in hypertension care, or retention, is a crucial but understudied step in optimizing patient outcomes. This systematic review leverages a hermeneutic methodology to identify, evaluate, and quantify the effects of interventions and contextual factors for improving retention for patients with hypertension. METHODS: We searched for articles that were published between 2000 and 2022 from multiple electronic databases, including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, and WHO International Trials Registry. We followed the latest version of the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guideline to report the findings for this review. We also synthesized the findings using a hermeneutic methodology for systematic reviews, which used an iterative process to review, integrate, analyze, and interpret evidence. RESULTS: From 4686 screened titles and abstracts, 18 unique studies from 9 countries were identified, including 10 (56%) randomized controlled trials (RCTs), 3 (17%) cluster RCTs, and 5 (28%) non-RCT studies. The number of participants ranged from 76 to 1562. The overall mean age range was 41-67 years, and the proportion of female participants ranged from 0% to 100%. Most (n = 17, 94%) studies used non-physician personnel to implement the proposed interventions. Fourteen studies (78%) implemented multilevel combinations of interventions. Education and training, team-based care, consultation, and Short Message Service reminders were the most common interventions tested. CONCLUSIONS: This review presents the most comprehensive findings on retention in hypertension care to date and fills the gaps in the literature, including the effectiveness of interventions, their components, and contextual factors. Adaptation of and implementing HIV care models, such differentiated service delivery, may be more effective and merit further study. REGISTRATION: CRD42021291368.

"I only seek treatment when I am ill": experiences of hypertension and diabetes care among adults living with HIV in urban Tanzania.

BACKGROUND: For adults living with HIV (ALHIV) and comorbidities, access to comprehensive healthcare services is crucial to achieving optimal health outcomes. This study aims to describe lived experiences, challenges, and coping strategies for accessing care for hypertension and/or diabetes (HTN/DM) in HIV care and treatment clinics (CTCs) and other healthcare settings. METHODOLOGY: We conducted a qualitative study that employed a phenomenological approach between January and April 2022 using a semi-structured interview guide in six HIV CTCs in Dar es Salaam, Tanzania. We purposively recruited 33 ALHIV with HTN (n = 16), DM (n = 10), and both (n = 7). Thematic content analysis was guided by the 5As framework of access to care. FINDINGS: The majority of the participants were females, between the ages of 54-73, and were recruited from regional referral hospitals. HIV CTCs at regional referral hospitals had more consistent provision of HTN screening services compared to those from district hospitals and health centers. Participants sought HTN/DM care at non-CTC health facilities due to the limited availability of such services at HIV CTCs. However, healthcare delivery for these conditions was perceived as unaccommodating and poorly coordinated. The need to attend multiple clinic appointments for the management of HTN/DM in addition to HIV care was perceived as frustrating, time-consuming, and financially burdensome. High costs of care and transportation, limited understanding of comorbidities, and the perceived complexity of HTN/DM care contributed to HTN/DM treatment discontinuity. As a means of coping, participants frequently monitored their own HTN/DM symptoms at home and utilized community pharmacies and dispensaries near their residences to check blood pressure and sugar levels and obtain medications. Participants expressed a preference for non-pharmaceutical approaches to comorbidity management such as lifestyle modification (preferred by young participants) and herbal therapies (preferred by older participants) because of concerns about side effects and perceived ineffectiveness of HTN/DM medications. Participants also preferred integrated care and focused patient education on multimorbidity management at HIV CTCs. CONCLUSION: Our findings highlight significant barriers to accessing HTN/DM care among ALHIV, mostly related to affordability, availability, and accessibility. Integration of NCD care into HIV CTCs, could greatly improve ALHIV health access and outcomes and align with patient preference.

Cross-country analysis of contextual factors and implementation strategies in under-5 mortality reduction in six low- and middle-income countries 2000-2015.

BACKGROUND: The Exemplars in Under-5 Mortality (U5M) was a multiple cases study of how six low- and middle-income countries (LMICs), Bangladesh, Ethiopia, Nepal, Peru, Rwanda, and Senegal, implemented health system-delivered evidence-based interventions (EBIs) to reduce U5M between 2000 and 2015 more effectively than others in their regions or with similar economic growth. Using implementation research, we conducted a cross-country analysis to compare decision-making pathways for how these countries chose, implemented, and adapted strategies for health system-delivered EBIs that mitigated or leveraged contextual factors to improve implementation outcomes in reducing amenable U5M. METHODS: The cross-country analysis was based on the hybrid mixed methods implementation research framework used to inform the country case studies. The framework included a common pathway of Exploration, Preparation, Implementation, Adaptation, and Sustainment (EPIAS). From the existing case studies, we extracted contextual factors which were barriers, facilitators, or determinants of strategic decisions; strategies to implement EBIs; and implementation outcomes including acceptability and coverage. We identified common factors and strategies shared by countries, and individual approaches used by countries reflecting differences in contextual factors and goals. RESULTS: We found the six countries implemented many of the same EBIs, often using similar strategies with adaptations to local context and disease burden. Common implementation strategies included use of data by decision-makers to identify problems and prioritize EBIs, determine implementation strategies and their adaptation, and measure outcomes; leveraging existing primary healthcare systems; and community and stakeholder engagement. We also found common facilitators included culture of donor and partner coordination and culture and capacity of data use, while common barriers included geography and culture and beliefs. We found evidence for achieving implementation outcomes in many countries and EBIs including acceptability, coverage, equity, and sustainability. DISCUSSION: We found all six countries used a common pathway to implementation with a number of strategies common across EBIs and countries which contributed to progress, either despite contextual barriers or by leveraging facilitators. The transferable knowledge from this cross-country study can be used by other countries to more effectively implement EBIs known to reduce amenable U5M and contribute to strengthening health system delivery now and in the future.

Examining the implementation of facility-based integrated management of childhood illness and insecticide treated nets in Bangladesh: lessons learned through implementation research.

BACKGROUND: Bangladesh significantly reduced under-5 mortality (U5M) between 2000 and 2015, despite its low economic development and projected high mortality rates in children aged under 5 years. A portion of this success was due to implementation of health systems-delivered evidence-based interventions (EBIs) known to reduce U5M. This study aims to understand how Bangladesh was able to achieve this success between 2000 and 2015. Implementation science studies such as this one provide insights on the implementation process that are not sufficiently documented in existing literature. METHODS: Between 2017 and 2020, we conducted mixed methods implementation research case studies to examine how six countries including Bangladesh outperformed their regional and economic peers in reducing U5M. Using existing data and reports supplemented by key informant interviews, we studied key implementation strategies and associated implementation outcomes for selected EBIs and contextual factors which facilitated or hindered this work. We used facility-based integrated management of childhood illnesses and insecticide treated nets as examples of two EBIs that were implemented successfully and with wide reach across the country to understand the strategies put in place as well as the facilitating and challenging contextual factors. RESULTS: Strategies which contributed to the successful implementation and wide coverage of the selected EBIs included community engagement, data use, and small-scale testing, important to achieving implementation outcomes such as effectiveness, reach and fidelity, although gaps persisted including in quality of care. Key contextual factors including a strong community-based health system, accountable leadership, and female empowerment facilitated implementation of these EBIs. Challenges included human resources for health, dependence on donor funding and poor service quality in the private sector. CONCLUSION: As countries work to reduce U5M, they should build strong community health systems, follow global guidance, adapt their implementation using local evidence as well as build sustainability into their programs. Strategies need to leverage facilitating contextual factors while addressing challenging ones.

Integrated Management of Childhood Illness implementation in Nepal: understanding strategies, context, and outcomes.

BACKGROUND: Health system-delivered evidence-based interventions (EBIs) are important to reducing amenable under-5 mortality (U5M). Implementation research (IR) can reduce knowledge gaps and decrease lags between new knowledge and its implementation in real world settings. IR can also help understand contextual factors and strategies useful to adapting EBIs and their implementation to local settings. Nepal has been a leader in dropping U5M including through adopting EBIs such as integrated management of childhood illness (IMCI). We use IR to identify strategies used in Nepal's adaptation and implementation of IMCI. METHODS: We conducted a mixed methods case study using an implementation research framework developed to understand how Nepal outperformed its peers between 2000-2015 in implementing health system-delivered EBIs known to reduce amenable U5M. We combined review of existing literature and data supplemented by 21 key informant interviews with policymakers and implementers, to understand implementation strategies and contextual factors that affected implementation outcomes. We extracted relevant results from the case study and used explanatory mixed methods to understand how and why Nepal had successes and challenges in adapting and implementing one EBI, IMCI. RESULTS: Strategies chosen and adapted to meet Nepal's specific context included leveraging local research to inform national decision-makers, pilot testing, partner engagement, and building on and integrating with the existing community health system. These cross-cutting strategies benefited from facilitating factors included community health system and structure, culture of data use, and local research capacity. Geography was a critical barrier and while substantial drops in U5M were seen in both the highest and lowest wealth quintiles, with the wealth equity gap decreasing from 73 to 39 per 1,000 live births from 2001 to 2016, substantial geographic inequities remained. CONCLUSIONS: Nepal's story shows that implementation strategies that are available across contexts were key to adopting and adapting IMCI and achieving outcomes including acceptability, effectiveness, and reach. The value of choosing strategies that leverage facilitating factors such as investments in community-based and facility-based approaches as well as addressing barriers such as geography are useful lessons for countries working to accelerate adaptation and implementation of strategies to implement EBIs to continue achieving child health targets.

Understanding rapid implementation from discovery to scale: Rwanda's implementation of rotavirus vaccines and PMTCT in the quest to reduce under-5 mortality.

BACKGROUND: Over the last eight decades, many evidence-based interventions (EBIs) have been developed to reduce amenable under-5 mortality (U5M). Implementation research can help reduce the lag between discovery and delivery, including as new EBIs emerge, or as existing ones are adapted based on new research. Rwanda was the first low-income African country to implement the rotavirus vaccine (RTV) and also adopted Option B+ for effective prevention of mother-to-child transmission (PMTCT) before the World Health Organization's (WHO) recommendation. We use implementation research to identify contextual factors and strategies associated with Rwanda's rapid uptake of these two EBIs developed or adapted during the study period. METHODS: We conducted a mixed methods case study informed by a hybrid implementation research framework to understand how Rwanda outperformed regional and economic peers in reducing U5M, focusing on the implementation of health system-delivered EBIs. The research included review of existing literature and data, and key informant interviews to identify implementation strategies and contextual factors that influenced implementation outcomes. We extracted relevant results from the broader case study and used convergent methods to understand successes and challenges of implementation of RTV, a newly introduced EBI, and PMTCT, an adapted EBI reflecting new research. RESULTS: We found several cross-cutting strategies that supported the rapid uptake and implementation of PMTCT, RTV, and leveraging facilitating contextual factors and identifying and addressing challenging ones. Key implementation strategies included community and stakeholder involvement and education, leveraging of in-country research capacity to drive adoption and adaptation, coordination of donors and implementing partners, data audit and feedback of coverage, a focus on equity, and integration into pre-existing systems, including community health workers and primary care. The availability of donor funding, culture of evidence-based decision-making, preexisting accountability systems, and rapid adoption of innovation were facilitating contextual factors. CONCLUSION: Implementation strategies which are generalizable to other settings were key to success in rapidly achieving high acceptability and coverage of both a new and an evolving EBI. Choosing strategies which leverage their facilitating factors and address barriers are important for other countries working to accelerate uptake of new EBIs and implement needed adaptations based on emerging evidence.

Inequity in the face of success: understanding geographic and wealth-based equity in success of facility-based delivery for under-5 mortality reduction in six countries.

BACKGROUND: Between 2000-2015, many low- and middle-income countries (LMICs) implemented evidence-based interventions (EBIs) known to reduce under-5 mortality (U5M). Even among LMICs successful in reducing U5M, this drop was unequal subnationally, with varying success in EBI implementation. Building on mixed methods multi-case studies of six LMICs (Bangladesh, Ethiopia, Nepal, Peru, Rwanda, and Senegal) leading in U5M reduction, we describe geographic and wealth-based equity in facility-based delivery (FBD), a critical EBI to reduce neonatal mortality which requires a trusted and functional health system, and compare the implementation strategies and contextual factors which influenced success or challenges within and across the countries. METHODS: To obtain equity gaps in FBD coverage and changes in absolute geographic and wealth-based equity between 2000-2015, we calculated the difference between the highest and lowest FBD coverage across subnational regions and in the FBD coverage between the richest and poorest wealth quintiles. We extracted and compared contextual factors and implementation strategies associated with reduced or remaining inequities from the country case studies. RESULTS: The absolute geographic and wealth-based equity gaps decreased in three countries, with greatest drops in Rwanda - decreasing from 50 to 5% across subnational regions and from 43 to 13% across wealth quintiles. The largest increases were seen in Bangladesh - from 10 to 32% across geography - and in Ethiopia - from 22 to 58% across wealth quintiles. Facilitators to reducing equity gaps across the six countries included leadership commitment and culture of data use; in some countries, community or maternal and child health insurance was also an important factor (Rwanda and Peru). Barriers across all the countries included geography, while country-specific barriers included low female empowerment subnationally (Bangladesh) and cultural beliefs (Ethiopia). Successful strategies included building on community health worker (CHW) programs, with country-specific adaptation of pre-existing CHW programs (Rwanda, Ethiopia, and Senegal) and cultural adaptation of delivery protocols (Peru). Reducing delivery costs was successful in Senegal, and partially successful in Nepal and Ethiopia. CONCLUSION: Variable success in reducing inequity in FBD coverage among countries successful in reducing U5M underscores the importance of measuring not just coverage but also equity. Learning from FBD interventions shows the need to prioritize equity in access and uptake of EBIs for the poor and in remote areas by adapting the strategies to local context.

Reducing the equity gap in under-5 mortality through an innovative community health program in Ethiopia: an implementation research study.

BACKGROUND: The Ethiopian government implemented a national community health program, the Health Extension Program (HEP), to provide community-based health services to address persisting access-related barriers to care using health extension workers (HEWs). We used implementation research to understand how Ethiopia leveraged the HEP to widely implement evidence-based interventions (EBIs) known to reduce under-5 mortality (U5M) and address health inequities. METHODS: This study was part of a six-country case study series using implementation research to understand how countries implemented EBIs between 2000-2015. Our mixed-methods research was informed by a hybrid implementation science framework using desk review of published and gray literature, analysis of existing data sources, and 11 key informant interviews. We used implementation of pneumococcal conjugate vaccine (PCV-10) and integrated community case management (iCCM) to illustrate Ethiopia's ability to rapidly integrate interventions into existing systems at a national level through leveraging the HEP and other implementation strategies and contextual factors which influenced implementation outcomes. RESULTS: Ethiopia implemented numerous EBIs known to address leading causes of U5M, leveraging the HEP as a platform for delivery to successfully introduce and scale new EBIs nationally. By 2014/15, estimated coverage of three doses of PCV-10 was at 76%, with high acceptability (nearly 100%) of vaccines in the community. Between 2000 and 2015, we found evidence of improved care-seeking; coverage of oral rehydration solution for treatment of diarrhea, a service included in iCCM, doubled over this period. HEWs made health services more accessible to rural and pastoralist communities, which account for over 80% of the population, with previously low access, a contextual factor that had been a barrier to high coverage of interventions. CONCLUSIONS: Leveraging the HEP as a platform for service delivery allowed Ethiopia to successfully introduce and scale existing and new EBIs nationally, improving feasibility and reach of introduction and scale-up of interventions. Additional efforts are required to reduce the equity gap in coverage of EBIs including PCV-10 and iCCM among pastoralist and rural communities. As other countries continue to work towards reducing U5M, Ethiopia's experience provides important lessons in effectively delivering key EBIs in the presence of challenging contextual factors.
