The role of context in implementation research for non-communicable diseases: Answering the 'how-to' dilemma

In Which Ways Does Community-Based Dental Education Facilitate Development of Professional Identity in Undergraduate Curricula? A Scoping Review

BACKGROUND

Community-Based Dental Education (CBDE) is becoming an integral part of undergraduate dental curricula globally. Literature has provided a wide range of benefits related to supporting the development of several professional skills such as communication and social interactions in community settings for dental students. While these skills are related to professional identity (PI) development, there has been little discussion linking CBDE with PI development in the current literature. To fill in this literature gap and explore pedagogical potentials to support PI for undergraduate healthcare curricula, this study provides a scoping review of the literature to analyse how published studies link CBDE to the development of PI.

METHODS

PRISMA extension for Scoping Reviews (PRISMA-ScR) was used to conduct the review. The review protocol was registered with Open Science Framework to ensure transparency. Multiple electronic databases were searched, followed by screening of the articles based on the inclusion and exclusion criteria. Qualitative analysis of the included articles was conducted using NVIVO by two independent reviewers.

RESULTS

A total of 4483 articles were identified from databases. The full-text screening was performed for 101 articles by two reviewers, out of which 35 articles were included in the analysis. The reviewed articles provide a diverse perspective of association and contribution to PI development through CBDE. Four dimensions were identified, including personal, clinical, interpersonal, and cultural. Most of the studies focussed on attaining clinical experience, while other studies explored confidence, teamwork skills, communication skills, and cultural awareness among undergraduate students in CBDE.

CONCLUSION

The current study explores the value of CBDE to foster PI development in undergraduate education. Although the existing literature identifies some elements in CBDE that may contribute to PI development, the link between it and CBDE does not appear to be articulated clearly. The results of the review provide practical implications for the future practice of CBDE and its relevance to professional identity development.

Contextual awareness, response and evaluation (CARE) of diabetes in poor urban communities in Ghana: the CARE diabetes project qualitative study protocol

Diabetes remains a major, global clinical and public health threat with consistent rises in prevalence around the world over the past four decades. Two-thirds of the projected increases in global diabetes prevalence to 2045 are expected to come from low- and middle-income countries, including those in sub-Saharan Africa. Ghana is typical of this trend. However, there are gaps in evidence regarding the appropriate development of interventions and well-targeted policies for diabetes prevention and treatment that pay due attention to relevant local conditions and influences. Due consideration to community perspectives of environmental influences on the causes of diabetes, access to appropriate health services and care seeking for diabetes prevention and management is warranted, especially in urban settings. The 'Contextual Awareness, Response and Evaluation (CARE): Diabetes in Ghana' project is a mixed methods study in Ga Mashie, Accra. An epidemiological survey is described elsewhere. Six qualitative studies utilising a range of methodologies are proposed in this protocol to generate a contextual understanding of type 2 diabetes mellitus in an urban poor population. They focus on community, care provider, and policy stakeholder perspectives with a focus on food markets and environmental influences, the demand and supply of health services, and the history of the Ga Mashie community and its inhabitants. The results will be shared with the community in Ga Mashie and with health policy stakeholders in Ghana and other settings where the findings may be usefully transferable for the development of community-based interventions for diabetes prevention and control.

Beyond autonomy: unpacking self-regulated and self-directed learning through the lens of learner agency- a scoping review

BACKGROUND

Learner agency involves students actively engaging in their learning process and shaping their educational experiences through autonomy, self-regulation, and decision-making. In professional education, particularly within health professions, learner agency is critical for fostering adaptability and lifelong learning. This scoping review explores how learner agency, alongside concepts such as self-regulated learning and self-directed learning, is addressed in undergraduate dental education, aiming to understand its implications and strategies for enhancing student agency in this context.

METHODS

The scoping review examined literature on self-regulated learning, self-directed learning and learner agency in undergraduate dental education from 1994-April 2024 across five databases: PubMed, Scopus, Embase, ProQuest Central, and Web of Science. A manual search of the cited references was also conducted. Relevant studies were screened, and the findings were summarized to offer a comprehensive overview and identify research gaps.

RESULTS

In total, 33 studies were included in the review. The results revealed a strong interconnection between intrapersonal, behavioral, and contextual dimensions in shaping learner agency through self-regulated learning and self-directed learning among undergraduate dental students. The studies analyzed, predominantly quantitative, highlighted the multifaceted relationships among self-regulated learning and self-directed learning and learner agency, emphasizing its significance for educational practice and policy.

CONCLUSIONS

Self-regulated learning and self-directed learning are crucial for developing learner agency, aiding undergraduate students' transition into independent professionals and fostering lifelong learning behaviors. Educational strategies should prioritize empowering students to become independent learners, reducing their reliance on faculty. Further research is needed to identify effective methods for promoting learner agency development among dental students.

Adapting and testing measures of organizational context in primary care clinics in KwaZulu-Natal, South Africa

BACKGROUND

Implementation science frameworks situate intervention implementation and sustainment within the context of the implementing organization and system. Aspects of organizational context such as leadership have been defined and measured largely within US health care settings characterized by decentralization and individual autonomy. The relevance of these constructs in other settings may be limited by differences like collectivist orientation, resource constraints, and hierarchical power structures. We aimed to adapt measures of organizational context in South African primary care clinics.

METHODS

We convened a panel of South African experts in social science and HIV care delivery and presented implementation domains informed by existing frameworks and prior work in South Africa. Based on panel input, we selected contextual domains and adapted candidate items. We conducted cognitive interviews with 25 providers in KwaZulu-Natal Province to refine measures. We then conducted a cross-sectional survey of 16 clinics with 5-20 providers per clinic (N = 186). We assessed reliability using Cronbach's alpha and calculated interrater agreement (awg) and intraclass correlation coefficient (ICC) at the clinic level. Within clinics with moderate agreement, we calculated correlation of clinic-level measures with each other and with hypothesized predictors - staff continuity and infrastructure - and a clinical outcome, patient retention on antiretroviral therapy.

RESULTS

Panelists emphasized contextual factors; we therefore focused on elements of clinic leadership, stress, cohesion, and collective problem solving (critical consciousness). Cognitive interviews confirmed salience of the domains and improved item clarity. After excluding items related to leaders' coordination abilities due to missingness and low agreement, all other scales demonstrated individual-level reliability and at least moderate interrater agreement in most facilities. ICC was low for most leadership measures and moderate for others. Measures tended to correlate within facility, and higher stress was significantly correlated with lower staff continuity. Organizational context was generally more positively rated in facilities that showed consistent agreement.

CONCLUSIONS

As theorized, organizational context is important in understanding program implementation within the South African health system. Most adapted measures show good reliability at individual and clinic levels. Additional revision of existing frameworks to suit this context and further testing in high and low performing clinics is warranted.

Burden of diseases due to high systolic blood pressure in the Middle East and North Africa region from 1990 to 2019

High systolic blood pressure (HSBP) is associated with several metabolic and non-metabolic disorders. This research aimed to document the deaths and disability-adjusted life-years (DALYs) attributable to HSBP in the Middle East and North Africa (MENA) region between 1990 and 2019, by age, sex, underlying cause and socio-demographic index (SDI). We used the methodological framework and data drawn from the Global Burden of Disease study 2019 to identify the burden of diseases attributable to HSBP, from 1990 to 2019, in the MENA region. The estimates reported were presented as counts, population-attributable fractions, and age-standardised rates (per 100,000), along with 95% uncertainty intervals. In 2019, 803.6 thousand (687.1 to 923.8) deaths were attributed to HSBP in MENA, which accounted for 25.9% (22.9-28.6%) of all deaths. The number of regional DALYs caused by HSBP in 2019 was 19.0 million (16.3-21.9 million), which accounted for 11.6% (10.1-13.3%) of all DALYs, and was 23.4% (15.9-31.5%) lower than in 1990. The highest age-standardised DALY rate for 2019 was observed in Afghanistan, with the lowest in Kuwait. Additionally, the DALY rate in MENA rose with age for both sexs. Furthermore, a negative linear relationship was found between SDI and the age-standardised DALY rates. The region has a substantial HSBP-related burden. Policymakers and healthcare professionals should prioritize interventions that effectively promote the early detection of HSBP, access to quality healthcare, and lifestyle modifications to mitigate the HSBP burden in the MENA countries.

Connecting the science and practice of implementation - applying the lens of context to inform study design in implementation research

The saying "horses for courses" refers to the idea that different people and things possess different skills or qualities that are appropriate in different situations. In this paper, we apply the analogy of "horses for courses" to stimulate a debate about how and why we need to get better at selecting appropriate implementation research methods that take account of the context in which implementation occurs. To ensure that implementation research achieves its intended purpose of enhancing the uptake of research-informed evidence in policy and practice, we start from a position that implementation research should be explicitly connected to implementation practice. Building on our collective experience as implementation researchers, implementation practitioners (users of implementation research), implementation facilitators and implementation educators and subsequent deliberations with an international, inter-disciplinary group involved in practising and studying implementation, we present a discussion paper with practical suggestions that aim to inform more practice-relevant implementation research.

Implementing a cirrhosis order set in a tertiary healthcare system: a theory-informed formative evaluation

BACKGROUND

Standardized order sets are a means of increasing adherence to clinical practice guidelines and improving the quality of patient care. Implementation of novel quality improvement initiatives like order sets can be challenging. Before the COVID-19 pandemic, we conducted a formative evaluation to understand healthcare providers' perspectives on implementing clinical changes and the individual, collective and organizational contextual factors that might impact implementation at eight hospital sites in Alberta, Canada.

METHODS

We utilized concepts from the Consolidated Framework for Implementation Research (CFIR) and Normalisation Process Theory (NPT) to understand the context, past implementation experiences, and perceptions of the cirrhosis order set. Eight focus groups were held with healthcare professionals caring for patients with cirrhosis. Data were coded deductively using relevant constructs of NPT and CFIR. A total of 54 healthcare professionals, including physicians, nurses, nurse practitioners, social workers and pharmacists and a physiotherapist, participated in the focus groups.

RESULTS

Key findings revealed that participants recognized the value of the cirrhosis order set and its potential to improve the quality of care. Participants highlighted potential implementation challenges, including multiple competing quality improvement initiatives, feelings of burnout, lack of communication between healthcare provider groups, and a lack of dedicated resources to support implementation.

CONCLUSIONS

Implementing a complex improvement initiative across clinician groups and acute care sites presents challenges. This work yielded insights into the significant influence of past implementation of similar interventions and highlighted the importance of communication between clinician groups and resources to support implementation. However, by using multiple theoretical lenses to illuminate what and how contextual and social processes will influence uptake, we can better anticipate challenges during the implementation process.

Factors That Influence the Use of eHealth in Home Care: Scoping Review and Cross-sectional Survey

BACKGROUND

In home care, eHealth implementation requires health care professionals and home care clients to change their behavior because they have to incorporate the use of eHealth into their daily routines. Knowledge of factors that influence the use of eHealth in home care is needed to optimize implementation strategies. However, a comprehensive overview of such factors is lacking.

OBJECTIVE

The aims of this study were to (1) provide insight into the types of eHealth that are used and preferred in home care and (2) identify factors that influence the use of eHealth in home care according to health care professionals and home care clients.

METHODS

A scoping review and online, cross-sectional survey were conducted sequentially. The survey was conducted among Dutch health care professionals with a nursing background who were working for a home care organization at the time. The capability, opportunity, motivation, behavior (COM-B) model, which posits that for any behavior (B) to occur, a person must have the capability (C), opportunity (O), and motivation (M) to perform the behavior, was used to identify influencing factors. The use of a theoretical model may contribute to a better understanding of how to achieve and sustain behavior change in clinical practice.

RESULTS

We included 30 studies in the scoping review. The most frequently studied type of eHealth was a telecommunication/telemonitoring system. The survey was completed by 102 participants. The most frequently used types of eHealth were electronic health records, social alarms, and online client portals. A health app was the most frequently preferred type of eHealth. We identified 22 factors that influence the use of eHealth in home care according to health care professionals and home care clients. Influencing factors were organized into the components of the COM-B model, namely capability (n=6), opportunity (n=10), and motivation (n=6). We found that there is no single influencing factor that is key to the complexity of eHealth implementation.

CONCLUSIONS

Different types of eHealth are used, and many types of eHealth are preferred by health care professionals. The identified factors that influence the use of eHealth in home care relate to all components of the COM-B model. These factors need to be addressed and embedded in implementation strategies of eHealth to optimize the use of eHealth in home care.

Qualitative evaluation of rapid implementation of remote blood pressure self-monitoring in pregnancy during Covid-19

In March 2020, the World Health Organisation named the severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2), which causes corona virus disease 2019 (COVID -19), as a pandemic. Pregnant women were considered at increased risk of developing severe COVID-19 after viral infection. In response maternity services reduced face-to-face consultations with high-risk pregnant women by supplying blood pressure monitors for supported self-monitoring. This paper explores the experiences of patients and clinicians of the rapid roll-out of supported self-monitoring programme in Scotland during the first and second wave of the COVID-19 pandemic. We conducted semi-structured telephone interviews with high-risk women and healthcare professionals who were using supported self-monitoring of blood pressure (BP) In four case studies during the COVID-19 pandemic. 20 women, 15 midwives and 4 obstetricians took part in the interviews. Interviews with healthcare professionals showed that while implementation occurred at pace and at scale across the National Health Service (NHS) in Scotland, implementation differed locally, resulting in mixed experiences. Study Participants observed several barriers and facilitators to implementation. Women value the simplicity of use and convenience of the digital communications platforms while health professionals were more interested in their impact on reducing workload for both women and health professionals largely found self-monitoring acceptable, with only a few exceptions. These results show that rapid change can occur in the NHS at a national level when there is a shared motivation. While self-monitoring is acceptable to most women, decisions regarding self-monitoring should be made jointly and on an individual basis.

Self-management experiences of haemodialysis patients with self-regulatory fatigue: A phenomenological study

AIM

To understand the real experiences of self-management in haemodialysis patients with self-regulatory fatigue, and to explore the influencing factors and coping strategies for patients with decreased self-management.

DESIGN

A qualitative study was carried out using the phenomenological analysis method.

METHODS

From 5 January to 25 February, 2022, semi-structured interviews were conducted with 18 haemodialysis patients in Lanzhou, China. Thematic analysis of the data was performed using the NVivo 12 software based on the 7 steps of Colaizzi's method. The study reporting followed the SRQR checklist.

RESULTS

Five themes and 13 sub-themes were identified. The main themes were difficulties in fluid restrictions and emotional management, hard to adhere to long-term self-management, uncertainty about self-management, influencing factors are complex and diverse and coping strategies should be further improved.

CONCLUSION

This study revealed the difficulties, uncertainty, influencing facts and coping strategies of self-management among haemodialysis patients with self-regulatory fatigue. A targeted program should be developed and implemented according to the characteristics of patients to reduce the level of self-regulatory fatigue and improve self-management.

IMPACT

Self-regulatory fatigue has a significant impact on the self-management behaviour of haemodialysis patients. Understanding the real experiences of self-management in haemodialysis patients with self-regulatory fatigue enables medical staff to correctly identify the occurrence of self-regulatory fatigue in time and help patients adopt positive coping strategies to keep effective self-management behaviour.

PATIENT OR PUBLIC CONTRIBUTION

Haemodialysis patients who met the inclusion criteria were recruited to participate in the study from a blood purification centre in Lanzhou, China.

Country and policy factors influencing the implementation of primary care-based alcohol screening: A comparison of Colombia, Mexico and Peru

Researchers and practitioners recognise the importance of context when implementing healthcare interventions, but the influence of wider environment is rarely mapped. This paper identifies the country and policy-related factors potentially explaining the country differences in outcomes of an intervention focused on improving detection and management of heavy alcohol use in primary care in Colombia, Mexico and Peru. Qualitative data obtained through interviews, logbooks and document analysis are used to explain quantitative data on number of alcohol screenings and screening providers in each of the countries. Existing alcohol screening standards in Mexico, and policy prioritisation of primary care and consideration of alcohol as a public health issue in Colombia and Mexico positively contributed to the outcome, while the COVID-19 pandemic had a negative impact. In Peru, the context was unsupportive due to a combination of: political instability amongst regional health authorities; lack of focus on strengthening primary care due to the expansion of community mental health centres; alcohol considered as an addiction rather than a public health issue; and the impact of COVID-19 on healthcare. We found that wider environment-related factors interacted with the intervention implemented and can help explain country differences in outcomes.

Methodological approaches to study context in intervention implementation studies: an evidence gap map

BACKGROUND

Within implementation science studies, contextual analysis is increasingly recognized as foundational to interventions' successful and sustainable implementation. However, inconsistencies between methodological approaches currently limit progress in studying context and guidance to standardize the use of those approaches is scant. Therefore, this study's objective was to systematically review and map current methodological approaches to contextual analysis in intervention implementation studies. The results would help us both to systematize the process of contextual analysis and identify gaps in the current evidence.

METHODS

We conducted an evidence gap map (EGM) based on literature data via a stepwise approach. First, using an empirically developed search string, we randomly sampled 20% of all intervention implementation studies available from PubMed per year (2015-2020). Second, we assessed included studies that conducted a contextual analysis. Data extraction and evaluation followed the Basel Approach for CoNtextual ANAlysis (BANANA), using a color-coded rating scheme. Also based on BANANA and on the Context and Implementation of Complex Interventions (CICI) framework-an implementation framework that pays ample attention to context- we created visual maps of various approaches to contextual analysis.

RESULTS

Of 15, 286 identified intervention implementation studies and study protocols, 3017 were screened for inclusion. Of those, 110 warranted close examination, revealing 22% that reported on contextual analysis. Only one study explicitly applied a framework for contextual analysis. Data were most commonly collected via surveys (n = 15) and individual interviews (n = 13). Ten studies reported mixed-methods analyses. Twenty-two assessed meso-level contextual and setting factors, with socio-cultural aspects most commonly studied. Eighteen described the use of contextual information for subsequent project phases (e.g., intervention development/adaption, selecting implementation strategies). Nine reported contextual factors' influences on implementation and/or effectiveness outcomes.

CONCLUSIONS

This study describes current approaches to contextual analysis in implementation science and provides a novel framework for evaluating and mapping it. By synthesizing our findings graphically in figures, we provide an initial evidence base framework that can incorporate new findings as necessary. We strongly recommend further development of methodological approaches both to conduct contextual analysis and to systematize the reporting of it. These actions will increase the quality and consistency of implementation science research.

Understanding context in the implementation of emergency obstetric and neonatal care in health facilities in Osun State, Nigeria- a mixed-methods study

BACKGROUND

Successful implementation of Emergency Obstetric and Neonatal Care (EmONC) is likely to improve pregnancy outcomes and is essential for quality maternity care. Context in implementation is described as factors that enabled or disabled implementation of interventions. While the context of implementation is important for the effectiveness of evidence-based interventions, the context of EmONC implementation has not been widely studied in Nigeria.

METHODS

The research design was cross-sectional descriptive. A mixed-methods approach was used to assess and explore the context of implementing EmONC in referral centres in Osun state. A purposive sampling technique was used to select the three tertiary health facilities in Osun State and six secondary health facilities from the six administrative zones in the State. A total of 186 healthcare providers in these referral centres participated in the quantitative part of the study, and eighteen in-depth interviews were conducted for its qualitative aspect. An adapted questionnaire from Context Assessment Index and an interview guide were used to collect data. Quantitative data were analysed using descriptive and inferential statistics at 0.05 significance level, while qualitative data were analysed using the thematic approach.

RESULTS

The percentage mean score of context strength in EmONC implementation was 63% ± 10.46 in secondary and 68% ± 10.47 in tertiary health facilities. There was a significant difference in the leadership (F (1, 184) = 8.35, p < 0.01), evaluation (F (1, 184) = 5.35, p = 0.02) and overall context (F (1, 184) = 6.46, p = 0.01) of EmONC implementation in secondary and tertiary health facilities. Emerging themes in EmONC context were: Resources for EmONC implementation; Demand for EmONC; Efficiency of funding; Institutional leadership; and Performance evaluation.

CONCLUSIONS

The context of EmONC implementation in the referral health facilities was generally weak. The secondary health facilities' weaknesses were worse compared to the tertiary health facilities. The five key contextual factors could inform strategies for improving EmONC implementation in health facilities to ensure improved access to care that will reduce deaths from obstetric complications in Nigeria.

Using implementation strategies in community settings: an introduction to the Expert Recommendations for Implementing Change (ERIC) compilation and future directions

In this commentary, we introduce public health practitioners and researchers to implementation science through an established compilation of implementation strategies. We provide terminology and examples for community settings so public health practitioners and researchers can use implementation strategies and document efforts using standard terminology. We also discuss the need for future work to determine the extent to which these implementation strategies work and are most useful in community settings, and ultimately, how health behaviors are impacted. We intend this commentary to serve as a dissemination strategy for implementation strategies and to contribute to knowledge in the growing field of implementation science in community settings.

Understanding the factors that impact effective uptake and maintenance of HIV care programs in South African primary health care clinics

BACKGROUND

There is an increasingly urgent gap in knowledge regarding the translation of effective HIV prevention and care programming into scaled clinical policy and practice. Challenges limiting the translation of efficacious programming into national policy include the paucity of proven efficacious programs that are reasonable for clinics to implement and the difficulty in moving a successful program from research trial to scaled programming. This study aims to bridge the divide between science and practice by exploring health care providers' views on what is needed to implement new HIV programs within existing HIV care.

METHODS

We conducted 20 in-depth interviews with clinic managers and clinic program implementing staff and five key informant interviews with district health managers overseeing programming in the uMgungundlovu District of KwaZulu-Natal Province, South Africa. Qualitative data were analyzed using a template approach. A priori themes were used to construct templates of relevance, including current care context for HIV and past predictors of successful implementation. Data were coded and analyzed by these templates.

RESULTS

Heath care providers identified three main factors that impact the integration of HIV programming into general clinical care: perceived benefits, resource availability, and clear communication. The perceived benefits of HIV programs hinged on the social validation of the program by early adopters. Wide program availability and improved convenience for providers and patients increased perceived benefit. Limited staffing capacity and a shortage of space were noted as resource constraints. Programs that specifically tackled these constraints through clinic decongestion were reported as being the most successful. Clear communication with all entities involved in clinic-based programs, some of which include external partners, was noted as central to maximizing program function and provider uptake.

CONCLUSIONS

Amid the COVID-19 pandemic, new programs are continuously being developed for implementation at the primary health care level. A better understanding of the factors that facilitate and prevent programmatic success will improve public health outcomes. Implementation is likely to be most successful when programs capitalize on endorsements from early adopters, tackle resource constraints, and foster greater communication among partners responsible for implementation.

Application of the Theoretical Framework of Acceptability to assess a telephone-facilitated health coaching intervention for the prevention and management of type 2 diabetes

Background

Lifestyle interventions focusing on diet and physical activity for the prevention and management of type 2 diabetes have been found effective. Acceptance of the intervention is crucial. The Theoretical Framework of Acceptability (TFA) developed by Sekhon et al. (2017) describes the multiple facets of acceptance: Affective attitude, burden, perceived effectiveness, ethicality, intervention coherence, opportunity costs and self-efficacy. The aims of this study were to develop and assess the psychometric properties of a measurement scale for acceptance of a telephone-facilitated health coaching intervention, based on the TFA; and to determine the acceptability of the intervention among participants living with diabetes or having a high risk of diabetes in socioeconomically disadvantaged areas in Stockholm.

Methods

This study was nested in the implementation trial SMART2D (Self-management approach and reciprocal learning for type 2 diabetes). The intervention consisted of nine telephone-facilitated health coaching sessions delivered individually over a 6-month period. The acceptability of the intervention was assessed using a questionnaire consisting of 19 Likert scale questions developed using Sekhon’s TFA. Exploratory factor analysis (EFA) was performed.

Results

Ratings from 49 participants (19 with type 2 diabetes and 30 at high risk of developing diabetes) in ages 38–65 were analyzed. The EFA on the acceptability scale revealed three factors with acceptable reliabilities: affective attitude (alpha 0.90), coherence and understanding (alpha 0.77), perceived burden (alpha 0.85), explaining 82% of the variance. Positive affect and coherence had high median scores and small variance. Median score for perceived burden was low, but with significant variance due to younger individuals and those at high risk reporting higher burden.

Conclusions

The telephone-facilitated health coaching intervention was perceived as acceptable by the study population using a questionnaire based on Sekhon’s TFA, with a wider variation in perceived burden seen among high risk and younger participants.

Illness Perceptions and Self-Management among People with Chronic Lung Disease and Healthcare Professionals: A Mixed-Method Study Identifying the Local Context

Self-management interventions (SMIs) may fail if they misalign with the local context. To optimize the implementation of SMIs in Chinese people with chronic lung disease (CLD), the local context was identified in Chinese primary care (PC) and secondary care (SC). A mixed-method study using semi-structured interviews and quantitative surveys was conducted on people with CLD and healthcare professionals (HCPs). The qualitative data was collected until data saturation was reached, and participants were invited to complete the survey after the interview. The qualitative data—analyzed with the framework approach—was triangulated with the quantitative data. A total of 52 participants completed the interviews, and 48 also finished the survey. Four themes were identified; (a) illness perceptions (e.g., patients had poor CLD knowledge and SM, inadequate resources lead to suboptimal disease control in PC); (b) self-management skills (e.g., most patients delayed exacerbation recognition and action, and some were admitted at the crisis point); (c) factors influencing self-management skills (e.g., (in)adequate disease knowledge and medical expenditure affordability); and (d) needs for self-management (e.g., increased disease knowledge, individualized self-management plan, eHealth, (healthcare insurance) policy support). Identified themes were dependent on each other and should be leveraged when implementing SMIs. Ultimately, such SMIs can optimize patient health outcomes.

Understanding dynamic complexity in context-Enriching contextual analysis in implementation science from a constructivist perspective

Context in implementation science includes not only characteristics of a setting in which an intervention will be delivered, but also social systems (e.g., interrelationships). Context is dynamic and interacts with both, the intervention and its implementation. Therefore, contextual analysis is recognized as an indispensable part of implementation science methodology: it provides the foundation for successful and sustainable implementation projects. Yet, driven by the prevailing post-positivist understanding of context, contextual analysis typically focuses on individual characteristics of context i.e., contextual dynamics and interactions go unnoticed. Conducting contextual analysis from a constructivist perspective promotes a multilayered approach, building a more comprehensive understanding of context, and thus facilitating successful implementation. In this article, we highlight the limitations of prevailing perspectives on context and approaches to contextual analysis. We then describe how contextual analysis can be enriched by working from a constructivist perspective. We finish with a discussion of the methodological and practical implications the proposed changes would entail. Emerging literature attempts to address both the concept of context and methods for contextual analysis. Various theories, models and frameworks consider context, however, many of these are reductionistic and do not acknowledge the dynamic nature of context or interactions within it. To complement recent conceptualizations of context, we suggest consider the following five constructivist concepts: 1) social space; 2) social place; 3) agency; 4) sensation; and 5) embodiment. We demonstrate the value of these concepts using COVID-19 vaccination uptake as an example and integrate the concepts in the Context and Implementation of Complex Interventions (CICI) framework-an implementation science framework that pays ample attention to context. To study context from a constructivist perspective, we also suggest additional considerations in view of methodologies for data collection and analysis, e.g., rapid ethnographic methods. A constructivist perspective contributes to a stronger conceptualization of contextual analysis. Considering the five constructivist concepts helps to overcome contextual analysis' current shortcomings, while revealing complex dynamics that usually go unnoticed. Thus, more comprehensive understanding of context can be developed to inform subsequent phases of an implementation project, thereby maximizing an intervention's uptake and sustainability.

Heavy Disease Burden of High Systolic Blood Pressure During 1990-2019: Highlighting Regional, Sex, and Age Specific Strategies in Blood Pressure Control

Objective: High systolic blood pressure (HSBP) remains the leading risk factor for mortality worldwide; however, limited data have revealed all-cause and cause-specific burdens attributed to HSBP at global and regional levels. This study aimed to estimate the global burden and priority diseases attributable to HSBP by region, sex, and age. Methods: Based on data and evaluation methods from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019, we estimated trends of age-standardized mortality rate (ASMR), the age-standardized rate of disability-adjusted life years (ASDRs), and the age-standardized rate of years lived with disability (ASYRs) attributable to HSBP during 1990-2019. Further, we analyzed cause-specific burdens attributable to HSBP by sex, age, year, and region. Results: Globally, a significant downtrend was found in the ASMR attributed to HSBP while ASYRs did not change substantially during 1990-2019. The majority of HSBP burden has shifted from high-middle sociodemographic index (SDI) regions to lower SDI regions. All-cause and most cause-specific burdens related to HSBP were improved in high SDI regions but the downtrends have stagnated in recent years. Although many cause-specific deaths associated with HSBP declined, chronic kidney disease (CKD) and endocarditis associated deaths were aggravated globally and ischemic heart disease (IHD), atrial fibrillation and flutter, aortic aneurysm (AA), and peripheral artery disease (PAD) associated deaths were on the rise in low/low-middle/middle SDI regions. Additionally, males had higher disease burdens than females. Middle-aged people with CVDs composed the major subgroup affected by HSBP while older people had the highest ASMRs associated with HSBP. Conclusions: This study revealed the global burden and priority diseases attributable to HSBP with wide variation by region, sex, and age, calling for effective and targeted strategies to reduce the prevalence and mortality of HSBP, especially in low/low-middle/middle SDI regions.

ASHA-Led Community-Based Groups to Support Control of Hypertension in Rural India Are Feasible and Potentially Scalable

Background: To improve the control of hypertension in low- and middle-income countries, we trialed a community-based group program co-designed with local policy makers to fit within the framework of India's health system. Trained accredited social health activists (ASHAs), delivered the program, in three economically and developmentally diverse settings in rural India. We evaluated the program's implementation and scalability. Methods: Our mixed methods process evaluation was guided by the United Kingdom Medical Research Council guidelines for complex interventions. Meeting attendance reports, as well as blood pressure and weight measures of attendees and adherence to meeting content and use of meeting tools were used to evaluate the implementation process. Thematic analysis of separate focus group discussions with participants and ASHAs as well as meeting reports and participant evaluation were used to investigate the mechanisms of impact. Results: Fifteen ASHAs led 32 community-based groups in three rural settings in the states of Kerala and Andhra Pradesh, Southern India. Overall, the fidelity of intervention delivery was high. Six meetings were delivered over a 3-month period to each of the intervention groups. The mean number of meetings attended by participants at each site varied significantly, with participants in Rishi Valley attending fewer meetings [mean (SD) = 2.83 (1.68)] than participants in West Godavari (Tukeys test, p = 0.009) and Trivandrum (Tukeys test, p < 0.001) and participants in West Godavari [mean (SD) = 3.48 (1.72)] attending significantly fewer meetings than participants in Trivandrum [mean (SD) = 4.29 (1.76), Tukeys test, p < 0.001]. Culturally appropriate intervention resources and the training of ASHAs, and supportive supervision of them during the program were critical enablers to program implementation. Although highly motivated during the implementation of the program ASHA reported historical issues with timely remuneration and lack of supportive supervision. Conclusions: Culturally appropriate community-based group programs run by trained and supported ASHAs are a successful and potentially scalable model for improving the control of hypertension in rural India. However, consideration of issues related to unreliable/insufficient remuneration for ASHAs, supportive supervision and their formal role in the wider health workforce in India will be important to address in future program scale up.

Understanding the Factors that Impact Effective Uptake and Integration of Health Programs in South African Primary Health Care Clinics

Introduction : There is an increasingly urgent gap in knowledge regarding the translation of effective HIV prevention and care programming into scaled clinical policy and practice. Challenges limiting the translation of efficacious programming into national policy include both the paucity of proven efficacious programs that are reasonable for clinics to implement and the difficulty in moving a successful program from research trial to scaled programming. This study aims to bridge the divide between science and practice by exploring health care providers’ views on what is needed to integrate of HIV programming into clinic systems. Methods : We conducted 20 in-depth interviews with clinic managers and clinic program implementing staff and 5 key informant interviews with district health managers overseeing programming in the uMgungundlovu District of KwaZulu-Natal Province, South Africa. Qualitative data were analyzed using a template approach. A priori themes were used to construct templates of relevance including current care context for HIV and past predictors of successful implementation. Data were coded and analyzed in accordance with these templates. Results : Heath care providers identified three main factors that impact integration of HIV programming into general clinical care: perceived benefits, resource availability, and clear communication. The perceived benefits of HIV programs hinged on the social validation of the program by early adopters. Wide program availability and improved convenience for providers and patients increased perceived benefit. Limited staffing capacity and a shortage of space were noted as resource constraints. Programs that specifically tackled these constraints through, for example clinic decongestion, were reported as being the most successful. Clear communication with all entities involved in clinic-based programs, some of which include external partners, was noted as central to maximizing program function and provider uptake. Conclusions : Amid the COVID-19 pandemic, new programs are already being developed for implementation at the primary health care level. A better understanding of the factors which both facilitate and prevent programmatic success will improve public health outcomes. Implementation is likely to be most successful when programs capitalize on endorsements from early adopters, tackle resource constraints, and foster greater communication among partners responsible for implementation.

Solving the problem of access to cardiovascular medicines: revolving fund pharmacy models in rural western Kenya

Availability of medicines for treatment of cardiovascular disease (CVD) is low in low-income and middle-income countries (LMIC). Supply chain models to improve the availability of quality CVD medicines in LMIC communities are urgently required. Our team established contextualised revolving fund pharmacies (RFPs) in rural western Kenya, whereby an initial stock of essential medicines was obtained through donations or purchase and then sold at a small mark-up price sufficient to replenish drug stock and ensure sustainability. In response to different contexts and levels of the public health system in Kenya (eg, primary versus tertiary), we developed and implemented three contextualised models of RFPs over the past decade, creating a network of 72 RFPs across western Kenya, that supplied 22 categories of CVD medicines and increased availability of essential CVD medications from <30% to 90% or higher. In one representative year, we were able to successfully supply 5 793 981 units of CVD and diabetes medicines to patients in western Kenya. The estimated programme running cost was US$6.5–25 per patient, serving as a useful benchmark for public governments to invest in medication supply chain systems in LMICs going forward. One important lesson that we have learnt from implementing three different RFP models over the past 10 years has been that each model has its own advantages and disadvantages, and we must continue to stay nimble and modify as needed to determine the optimal supply chain model while ensuring consistent access to essential CVD medications for patients living in these settings.

A systematic approach to context-mapping to prepare for health interventions: development and validation of the SETTING-tool in four countries

Effectiveness of health interventions can be substantially impaired by implementation failure. Context-driven implementation strategies are critical for successful implementation. However, there is no practical, evidence-based guidance on how to map the context in order to design context-driven strategies. Therefore, this practice paper describes the development and validation of a systematic context-mapping tool. The tool was cocreated with local end-users through a multistage approach. As proof of concept, the tool was used to map beliefs and behaviour related to chronic respiratory disease within the FRESH AIR project in Uganda, Kyrgyzstan, Vietnam and Greece. Feasibility and acceptability were evaluated using the modified Conceptual Framework for Implementation Fidelity. Effectiveness was assessed by the degree to which context-driven adjustments were made to implementation strategies of FRESH AIR health interventions. The resulting Setting-Exploration-Treasure-Trail-to-Inform-implementatioN-strateGies (SETTING-tool) consisted of six steps: (1) Coset study priorities with local stakeholders, (2) Combine a qualitative rapid assessment with a quantitative survey (a mixed-method design), (3) Use context-sensitive materials, (4) Collect data involving community researchers, (5) Analyse pragmatically and/or in-depth to ensure timely communication of findings and (6) Continuously disseminate findings to relevant stakeholders. Use of the tool proved highly feasible, acceptable and effective in each setting. To conclude, the SETTING-tool is validated to systematically map local contexts for (lung) health interventions in diverse low-resource settings. It can support policy-makers, non-governmental organisations and health workers in the design of context-driven implementation strategies. This can reduce the risk of implementation failure and the waste of resource potential. Ultimately, this could improve health outcomes.

Health extension workers' perceived health system context and health post preparedness to provide services: a cross-sectional study in four Ethiopian regions

OBJECTIVE

The health system context influences the implementation of evidence-based practices and quality of healthcare services. Ethiopia aims at reaching universal health coverage but faces low primary care utilisation and substandard quality of care. We assessed the health extension workers' perceived context and the preparedness of health posts to provide services.

SETTING

This study was part of evaluating a complex intervention in 52 districts of four regions of Ethiopia. This paper used the endline data collected from December 2018 to February 2019.

PARTICIPANTS

A total of 152 health posts and health extension workers serving selected enumeration areas were included.

OUTCOME MEASURES

We used the Context Assessment for Community Health (COACH) tool and the Service Availability and Readiness Assessment tool.

RESULTS

Internal reliability of COACH was satisfactory. The dimensions community engagement, work culture, commitment to work and leadership all scored high (mean 3.75-4.01 on a 1-5 scale), while organisational resources, sources of knowledge and informal payments scored low (1.78-2.71). The general service readiness index was 59%. On average, 67% of the health posts had basic amenities to provide services, 81% had basic equipment, 42% had standard precautions for infection prevention, 47% had test capacity for malaria and 58% had essential medicines.

CONCLUSION

The health extension workers had a good relationship with the local community, used data for planning, were highly committed to their work with positive perceptions of their work culture, a relatively positive attitude regarding their leaders, and reported no corruption or informal payments. In contrast, they had insufficient sources of information and a severe lack of resources. The health post preparedness confirmed the low level of resources and preparedness for services. These findings suggest a significant potential contribution by health extension workers to Ethiopia's primary healthcare, provided that they receive improved support, including new information and essential resources.

Assessing a national policy on strengthening chronic care in primary care settings of a middle-income country using patients' perspectives

Background

To improve care for patients with chronic diseases, a recent policy initiative in Thailand focused on strengthening primary care based on the concept of Chronic Care Model (CCM). This study aimed to assess the perception of patients about the health care services after the implementation.

Methods

We conducted a cross-sectional survey of 4071 patients with hypertension and/or diabetes registered with 27 primary care units and 11 hospital non-communicable diseases (NCDs) clinics in 11 provinces.

The patients were interviewed using a validated questionnaire of the Patient Assessment of Chronic Illness Care. Upgraded primary care units (PCUs) were ordinary PCUs with the multi-professional team including a physician. Trained upgraded PCUs were upgraded PCUs with the training input. Structural equation modeling was used to create subscale scores for CCM and 5 A model characteristics. Mixed effect logistic models were employed to examine the association of subscales (high vs low score) of patient perception of the care quality with type of PCUs.

Results

Compared to hospital NCD clinics, ordinary PCUs were the best in the odds of receiving high score for every CCM subscale (ORs: 1.46–1.85; p < 0.05), whereas the trained upgraded PCUs were better in terms of follow-up (ORs:1.37; p < 0.05), and the upgraded PCU did not differ in all domains. According to the 5 A model subscales, patient assessment also revealed better performance of ordinary PCUs in all domains compared to hospital NCD clinics whereas upgraded PCUs and trained upgraded PCUs did so in some domains. Seeing the same doctor on repeated visits (ORs: 1.82–2.17; p < 0.05) or having phone contacts with the providers (ORs:1.53–1.99; p < 0.05) were found beneficial using CCM subscales and the 5A model subscales. However, patient assessment by both subscales did not demonstrate a statistically significant association across health insurance status.

Conclusions

The policy implementation might not satisfy the patients’ perception on quality of chronic care according to the CCM and the 5A model subscale. However, the arrangement of chronic care with patients seeing the same doctors or patients having telephone contact with healthcare providers may satisfy the patients’ perceived needs.

Patients' and healthcare professionals' beliefs, perceptions and needs towards chronic kidney disease self-management in China: a qualitative study

OBJECTIVES

To support the adaptation and translation of an evidence-based chronic kidney disease (CKD) self-management intervention to the Chinese context, we examined the beliefs, perceptions and needs of Chinese patients with CKD and healthcare professionals (HCPs) towards CKD self-management.

DESIGN

A basic interpretive, cross-sectional qualitative study comprising semistructured interviews and observations.

SETTING

One major tertiary referral hospital in Henan province, China.

PARTICIPANTS

11 adults with a diagnosis of CKD with CKD stages G1-G5 and 10 HCPs who worked in the Department of Nephrology.

RESULTS

Four themes emerged: (1) CKD illness perceptions, (2) understanding of and motivation towards CKD self-management, (3) current CKD practice and (4) barriers, (anticipated) facilitators and needs towards CKD self-management. Most patients and HCPs solely mentioned medical management of CKD, and self-management was largely unknown or misinterpreted as adherence to medical treatment. Also, the majority of patients only mentioned performing disease-specific acts of control and not, for instance, behaviour for coping with emotional problems. A paternalistic patient-HCP relationship was often present. Finally, the barriers, facilitators and needs towards CKD self-management were frequently related to knowledge and environmental context and resources.

CONCLUSIONS

The limited understanding of CKD self-management, as observed, underlines the need for educational efforts on the use and benefits of self-management before intervention implementation. Also, specific characteristics and needs within the Chinese context need to guide the development or tailoring of CKD self-management interventions. Emphasis should be placed on role management and emotional coping skills, while self-management components should be tailored by addressing the existing paternalistic patient-HCP relationship. The use of electronic health innovations can be an essential facilitator for implementation.

Bipolar disorders

Bipolar disorders are a complex group of severe and chronic disorders that includes bipolar I disorder, defined by the presence of a syndromal, manic episode, and bipolar II disorder, defined by the presence of a syndromal, hypomanic episode and a major depressive episode. Bipolar disorders substantially reduce psychosocial functioning and are associated with a loss of approximately 10-20 potential years of life. The mortality gap between populations with bipolar disorders and the general population is principally a result of excess deaths from cardiovascular disease and suicide. Bipolar disorder has a high heritability (approximately 70%). Bipolar disorders share genetic risk alleles with other mental and medical disorders. Bipolar I has a closer genetic association with schizophrenia relative to bipolar II, which has a closer genetic association with major depressive disorder. Although the pathogenesis of bipolar disorders is unknown, implicated processes include disturbances in neuronal-glial plasticity, monoaminergic signalling, inflammatory homoeostasis, cellular metabolic pathways, and mitochondrial function. The high prevalence of childhood maltreatment in people with bipolar disorders and the association between childhood maltreatment and a more complex presentation of bipolar disorder (eg, one including suicidality) highlight the role of adverse environmental exposures on the presentation of bipolar disorders. Although mania defines bipolar I disorder, depressive episodes and symptoms dominate the longitudinal course of, and disproportionately account for morbidity and mortality in, bipolar disorders. Lithium is the gold standard mood-stabilising agent for the treatment of people with bipolar disorders, and has antimanic, antidepressant, and anti-suicide effects. Although antipsychotics are effective in treating mania, few antipsychotics have proven to be effective in bipolar depression. Divalproex and carbamazepine are effective in the treatment of acute mania and lamotrigine is effective at treating and preventing bipolar depression. Antidepressants are widely prescribed for bipolar disorders despite a paucity of compelling evidence for their short-term or long-term efficacy. Moreover, antidepressant prescription in bipolar disorder is associated, in many cases, with mood destabilisation, especially during maintenance treatment. Unfortunately, effective pharmacological treatments for bipolar disorders are not universally available, particularly in low-income and middle-income countries. Targeting medical and psychiatric comorbidity, integrating adjunctive psychosocial treatments, and involving caregivers have been shown to improve health outcomes for people with bipolar disorders. The aim of this Seminar, which is intended mainly for primary care physicians, is to provide an overview of diagnostic, pathogenetic, and treatment considerations in bipolar disorders. Towards the foregoing aim, we review and synthesise evidence on the epidemiology, mechanisms, screening, and treatment of bipolar disorders.

Health system interventions for adults with type 2 diabetes in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Effective health system interventions may help address the disproportionate burden of diabetes in low- and middle-income countries (LMICs). We assessed the impact of health system interventions to improve outcomes for adults with type 2 diabetes in LMICs.

METHODS AND FINDINGS

We searched Ovid MEDLINE, Cochrane Library, EMBASE, African Index Medicus, LILACS, and Global Index Medicus from inception of each database through February 24, 2020. We included randomized controlled trials (RCTs) of health system interventions targeting adults with type 2 diabetes in LMICs. Eligible studies reported at least 1 of the following outcomes: glycemic change, mortality, quality of life, or cost-effectiveness. We conducted a meta-analysis for the glycemic outcome of hemoglobin A1c (HbA1c). GRADE and Cochrane Effective Practice and Organisation of Care methods were used to assess risk of bias for the glycemic outcome and to prepare a summary of findings table. Of the 12,921 references identified in searches, we included 39 studies in the narrative review of which 19 were cluster RCTs and 20 were individual RCTs. The greatest number of studies were conducted in the East Asia and Pacific region (n = 20) followed by South Asia (n = 7). There were 21,080 total participants enrolled across included studies and 10,060 total participants in the meta-analysis of HbA1c when accounting for the design effect of cluster RCTs. Non-glycemic outcomes of mortality, health-related quality of life, and cost-effectiveness had sparse data availability that precluded quantitative pooling. In the meta-analysis of HbA1c from 35 of the included studies, the mean difference was -0.46% (95% CI -0.60% to -0.31%, I2 87.8%, p < 0.001) overall, -0.37% (95% CI -0.64% to -0.10%, I2 60.0%, n = 7, p = 0.020) in multicomponent clinic-based interventions, -0.87% (-1.20% to -0.53%, I2 91.0%, n = 13, p < 0.001) in pharmacist task-sharing studies, and -0.27% (-0.50% to -0.04%, I2 64.1%, n = 7, p = 0.010) in trials of diabetes education or support alone. Other types of interventions had few included studies. Eight studies were at low risk of bias for the summary assessment of glycemic control, 15 studies were at unclear risk, and 16 studies were at high risk. The certainty of evidence for glycemic control by subgroup was moderate for multicomponent clinic-based interventions but was low or very low for other intervention types. Limitations include the lack of consensus definitions for health system interventions, differences in the quality of underlying studies, and sparse data availability for non-glycemic outcomes.

CONCLUSIONS

In this meta-analysis, we found that health system interventions for type 2 diabetes may be effective in improving glycemic control in LMICs, but few studies are available from rural areas or low- or lower-middle-income countries. Multicomponent clinic-based interventions had the strongest evidence for glycemic benefit among intervention types. Further research is needed to assess non-glycemic outcomes and to study implementation in rural and low-income settings.

Implementing a context-driven awareness programme addressing household air pollution and tobacco: a FRESH AIR study

Most patients with chronic respiratory disease live in low-resource settings, where evidence is scarcest. In Kyrgyzstan and Vietnam, we studied the implementation of a Ugandan programme empowering communities to take action against biomass and tobacco smoke. Together with local stakeholders, we co-created a train-the-trainer implementation design and integrated the programme into existing local health infrastructures. Feasibility and acceptability, evaluated by the modified Conceptual Framework for Implementation Fidelity, were high: we reached ~15,000 Kyrgyz and ~10,000 Vietnamese citizens within budget (~€11,000/country). The right engaged stakeholders, high compatibility with local contexts and flexibility facilitated programme success. Scores on lung health awareness questionnaires increased significantly to an excellent level among all target groups. Behaviour change was moderately successful in Vietnam and highly successful in Kyrgyzstan. We conclude that contextualising the awareness programme to diverse low-resource settings can be feasible, acceptable and effective, and increase its sustainability. This paper provides guidance to translate lung health interventions to new contexts globally.

Implementing lung health interventions in low- and middle-income countries: a FRESH AIR systematic review and meta-synthesis

The vast majority of patients with chronic respiratory disease live in low- and middle-income countries (LMICs). Paradoxically, relevant interventions often fail to be effective particularly in these settings, as LMICs lack solid evidence on how to implement interventions successfully. Therefore, we aimed to identify factors critical to the implementation of lung health interventions in LMICs, and weigh their level of evidence.This systematic review followed Cochrane methodology and Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) reporting standards. We searched eight databases without date or language restrictions in July 2019, and included all relevant original, peer-reviewed articles. Two researchers independently selected articles, critically appraised them (using Critical Appraisal Skills Programme (CASP)/Meta Quality Appraisal Tool (MetaQAT)), extracted data, coded factors (following the Consolidated Framework for Implementation Research (CFIR)), and assigned levels of confidence in the factors (via Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual)). We meta-synthesised levels of evidence of the factors based on their frequency and the assigned level of confidence (PROSPERO:CRD42018088687).We included 37 articles out of 9111 screened. Studies were performed across the globe in a broad range of settings. Factors identified with a high level of evidence were: 1) "Understanding needs of local users"; 2) ensuring "Compatibility" of interventions with local contexts (cultures, infrastructures); 3) identifying influential stakeholders and applying "Engagement" strategies; 4) ensuring adequate "Access to knowledge and information"; and 5) addressing "Resource availability". All implementation factors and their level of evidence were synthesised in an implementation tool.To conclude, this study identified implementation factors for lung health interventions in LMICs, weighed their level of evidence, and integrated the results into an implementation tool for practice. Policymakers, non-governmental organisations, practitioners, and researchers may use this FRESH AIR (Free Respiratory Evaluation and Smoke-exposure reduction by primary Health cAre Integrated gRoups) Implementation tool to develop evidence-based implementation strategies for related interventions. This could increase interventions' implementation success, thereby optimising the use of already-scarce resources and improving health outcomes.

Innovative Implementation Strategies for Hypertension Control in Low- and Middle-Income Countries: a Narrative Review

PURPOSE OF REVIEW

This review summarizes the most recent and innovative implementation strategies for hypertension control in low- and middle-income countries (LMICs).

RECENT FINDINGS

Implementation strategies from Latin America, Africa, and Asia were organized across three levels: community, health system, and policy/population. Multicomponent interventions involving task-shifting strategies, with or without mobile health tools, had the most supporting evidence, with policy or population-level interventions having the least, focused only on salt reduction with mixed results. More research is needed to better understand how context affects intervention implementation. There is an emerging evidence base for implementation strategies for hypertension control and CVD risk reduction in LMICs at the community and health system levels, but further research is needed to determine the most effective policy and population-level strategies. How to best account for local context in adapting and implementing these evidence-based interventions in LMICs still remains largely unknown. Accelerating the translation of this implementation research into policy and practice is imperative to improve health and save lives globally.

Snapshots of Urban and Rural Food Environments: EPOCH-Based Mapping in a High-, Middle-, and Low-Income Country from a Non-Communicable Disease Perspective

A changing food environment is implicated as a primary contributor to the increasing levels of non-communicable diseases (NCDs). This study aimed to generate snapshots of selected external food environments to inform intervention strategies for NCD prevention in three countries: Uganda (low income), South Africa (middle income) and Sweden (high income), with one matched pair of urban-rural sites per country. Fifty formal and informal food retail outlets were assessed, and descriptive and comparative statistical analyses were performed. We found that formal food retail outlets in these countries had both positive and negative traits, as they were the main source of basic food items but also made unhealthy food items readily available. The Ugandan setting had predominantly informal outlets, while the Swedish setting had primarily formal outlets and South Africa had both, which fits broadly into the traditional (Uganda), mixed (South Africa) and modern (Sweden) conceptualized food systems. The promotion of unhealthy food products was high in all settings. Uganda had the highest in-community advertising, followed by South Africa and Sweden with the lowest, perhaps related to differences in regulation and implementation. The findings speak to the need to address contextual differences in NCD-related health interventions by incorporating strategies that address the food environment, and for a critical look at regulations that tackle key environment-related factors of food on a larger scale.

The Meta Salud Diabetes Implementation Study: Qualitative Methods to Assess Integration of a Health Promotion Intervention Into Primary Care to Reduce CVD Risk Among an Underserved Population With Diabetes in Sonora, Mexico

Background: Within health promotion research, there is a need to assess strategies for integration and scale up in primary care settings. Hybrid interventions that combine clinical effectiveness trials with implementation studies can elicit important contextual information on facilitators and barriers to integration within a health care system. This article describes lessons learned in developing and implementing a qualitative study of a cluster-randomized controlled trial (RCT) to reduce cardiovascular disease (CVD) among people with diabetes in Sonora, Mexico, 2015–2019.

Methods:The research team worked cooperatively with health center personnel from 12 Centers that implemented the intervention. The study used observations, stakeholder meetings, case studies, staff interviews and decision maker interviews to explore issues such as staff capacity, authority, workflow, space, and conflicting priorities, as well as patients' response to the program within the clinical context and their immediate social environments. Applying a multi-layered contextual framework, two members of the research team coded an initial sample of the data to establish inclusion criteria for each contextual factor. The full team finalized definitions and identified sub nodes for the final codebook.

Results: Characteristics of management, staffing, and the local environment were identified as essential to integration and eventual adoption and scale up across the health system. Issues included absence of standardized training and capacity building in chronic disease and health promotion, inadequate medical supplies, a need for program monitoring and feedback, and lack of interdisciplinary support for center staff. Lack of institutional support stemming from a curative vs. preventive approach to care was a barrier for health promotion efforts. Evolving analysis, interpretation, and discussion resulted in modifications of flexible aspects of the intervention to realities of the health center environment.

Conclusion: This study illustrates that a robust and comprehensive qualitative study of contextual factors across a social ecological spectrum is critical to elucidating factors that will promote future adoption and scale up of health promotion programs in primary care. Application of conceptual frameworks and health behavior theory facilitates identification of facilitators and barriers across contexts.

Built Environment and Health Behaviors: Deconstructing the Black Box of Interactions-A Review of Reviews

A review of reviews following a scoping review study design was conducted in order to deconstruct the black box of interactions between the built environment and human behaviors pertaining to physical activity and/or diet. In the qualitative analysis 107 records were included, 45 of which were also coded. Most review papers confirmed the influence of the built environment on the behaviors of interest with some noting that a same built environment feature could have different behavioral outcomes. The conceptual model developed sheds light on these mixed results and brings out the role of several personal and behavioral factors in the shift from the measured to the perceived built environment. This shift was found to shape individuals' behaviors critically and to have the power of redefining the strength of every interaction. Apart from its theoretical relevance, this model has high practical relevance especially for the design and implementation of interventions with a behavioral component. Intervention researchers can use the model developed to identify and label the built environment and individual factors that can be measured objectively or perceived as facilitators, concurrent options and barriers, in order to develop comprehensive and multi-component intervention strategies.
