Challenges to implementing planning processes in Brazilian health regions.

OBJECTIVE: To recognize elements that facilitated or hindered the PlanificaSUS implementation stages. METHODS: A multiple case study was carried out in four pre-selected health regions in Brazil-Belo Jardim (PE), Fronteira Oeste (RS), Sul-Mato-Grossense (MT) and Valença (BA) using systemic arterial hypertension and maternal and child care as tracer conditions. Participant observation (in regional interagency commissions) and in-depth interviews with key informants from state and municipal management and primary health care and specialized outpatient care service professionals within the project were carried out in these four regions. Analysis was built according to political, technical-operational, and contextual dimensions. RESULTS: The political dimension evinced that the regions found the project an opportunity to articulate states and municipalities and an important political bet to build networks and lines of care but that there remained much to be faced in the disputes related to building the Unified Health System (SUS). In the technical operational dimension, it is important to consider that primary health care stimulated a culture of local planning and favored traditional tools to organize and improve it, such as organizing registrations, agendas, and demands. However, centralized training and planning-inducing processes fail to always respond to local needs and can produce barriers to implementation. CONCLUSIONS: It is worth considering the central and regional role of state managers in the commitment related to the project and the effect of mobilizing primary health care and expanding its power. There remains much to be faced in the disputes at stake in bullring SUS.

An implementation strategy postmortem method developed in the VA rural Transitions Nurse Program to inform spread and scale-up.

BACKGROUND: High-quality implementation evaluations report on intervention fidelity and adaptations made, but a practical process for evaluating implementation strategies is needed. A retrospective method for evaluating implementation strategies is also required as prospective methods can be resource intensive. This study aimed to establish an implementation strategy postmortem method to identify the implementation strategies used, when, and their perceived importance. We used the rural Transitions Nurse Program (TNP) as a case study, a national care coordination intervention implemented at 11 hospitals over three years. METHODS: The postmortem used a retrospective, mixed method, phased approach. Implementation team and front-line staff characterized the implementation strategies used, their timing, frequency, ease of use, and their importance to implementation success. The Expert Recommendations for Implementing Change (ERIC) compilation, the Quality Enhancement Research Initiative phases, and Proctor and colleagues' guidance were used to operationalize the strategies. Survey data were analyzed descriptively, and qualitative data were analyzed using matrix content analysis. RESULTS: The postmortem method identified 45 of 73 ERIC strategies introduced, including 41 during pre-implementation, 37 during implementation, and 27 during sustainment. External facilitation, centralized technical assistance, and clinical supervision were ranked as the most important and frequently used strategies. Implementation strategies were more intensively applied in the beginning of the study and tapered over time. CONCLUSIONS: The postmortem method identified that more strategies were used in TNP than planned and identified the most important strategies from the perspective of the implementation team and front-line staff. The findings can inform other implementation studies as well as dissemination of the TNP intervention.

The Collaborative Service Design Playbook to plan, design, and implement sustainable health services for impact.

This paper sets out the Collaborative Service Design Playbook, to guide planning, design, and implementation of co-created health services. Successful health service development and implementation is best guided by theoretically informed approaches; however, organisations often lack design and implementation know-how and have difficulty applying it. This study seeks to improve health service design and potential for scale-up by proposing a tool to guide an end-to-end process, drawing together service design, co-design, and implementation science; and exploring the tool's feasibility to establish a sustainable service solution developed with participants and experts that is scalable and sustainable. The Collaborative Service Design Playbook phases include, (1) Define the opportunity and initiatives, (2) Design the concept and prototype, (3) Deliver to scale and evaluate; and (4) Optimise to transform and sustain. This paper has implications for health marketing through providing an end-to-end approach with phased guidance for health service development, implementation, and scale up.

Findings from an Organizational Context Survey to Inform the Implementation of a Collaborative Care Study for Co-occurring Disorders.

Primary care is an opportune setting to deliver treatments for co-occurring substance use and mental health disorders; however, treatment delivery can be challenging due multi-level implementation barriers. Documenting organizational context can provide insight into implementation barriers and the adaptation of new processes into usual care workflows. This study surveyed primary care and behavioral health staff from 13 clinics implementing a collaborative care intervention for opioid use disorders co-occurring with PTSD and/or depression as part of a multisite randomized controlled trial. A total of 323 completed an online survey for a 60% response rate. The Consolidated Framework for Implementation Research guided this assessment of multi-level factors that influence implementation. Most areas for improvement focused on inner setting (organizational level) constructs whereas individual-level constructs tended to be strengths. This work addresses a research gap regarding how organizational analyses can be used prior to implementation and provides practical implications for researchers and clinic leaders.

Reflection on the application of the Consolidated Framework for Implementation Research to a national policy to improve inclusion of people with disabilities.

People with disabilities face many barriers in the built environment impacting their mobility, health, and social participation. In the US, under the Americans with Disabilities Act (ADA), municipalities were required to develop and implement barrier-removal plans for pedestrian infrastructure, called ADA transition plans, but very few have done so. Many communities know they need a plan but do not know how to get it done because of a lack of understanding of the many different implementation considerations. Implementation science offers a useful approach for understanding complex policy implementation such as ADA plans. This paper provides a reflection on the adaptation of the Consolidated Framework for Implementation Research (CFIR) to evaluate the implementation of ADA transition planning. To apply the CFIR, we tailored the construct definitions and modified them to fit the specific context of the ADA transition planning process. We documented the constructs that were more challenging to apply, those that were not relevant, and those that were particularly useful. This paper can serve as a valuable example that other researchers can use when considering adapting the CFIR or other implementation frameworks for the evaluation of complex social policy beyond the ADA.

Healthy eating and active living policy, systems, and environmental changes in rural Louisiana: a contextual inquiry to inform implementation strategies.

BACKGROUND: Healthy eating and active living policy, systems, and environmental (PSE) changes are implemented across the United States through Cooperative Extension. However, translating multisector PSE changes to practice in community settings is challenging and there is a lack of knowledge about barriers and facilitators to PSE changes among state Extension systems using standardized frameworks. Therefore, a research-to-practice partnership effort aimed to identify Louisiana Cooperative Extension Service Family and Consumer Science (LFCS) practitioners' barriers and facilitators to implementing PSE changes in rural Louisiana communities. METHODS: A qualitative approach using the 2022 Consolidated Framework for Implementation Research (2022 CFIR) was used. Focus group discussions were conducted at five LFCS regional trainings between February and May 2022. All LFCS practitioners with any level of experience implementing healthy eating and active living PSE changes were eligible to participate, with emphasis on understanding efforts within more rural communities. Focus group discussions were audio-recorded and transcribed verbatim. Researchers analyzed qualitative data using the constant comparison method and 2022 CFIR domains and constructs including Inner Setting (LFCS organization), Outer Setting (rural Louisiana communities), Innovation (PSE changes), and Individuals (PSE change implementation actors/partners). RESULTS: Across the five regions, LFCS practitioners (n = 40) described more barriers (n = 210) than facilitators (n = 100); findings were often coded with multiple 2022 CFIR domains. Reported Inner Setting barriers were lack of formal or informal information sharing and lack of access to knowledge and information. Outer Setting barriers included sustaining and initiating community partnerships and local environmental or political conditions. Individual barriers included a lack of time and expertise, and Innovation barriers included the complex nature of rural PSE changes. Facilitators were mentioned at multiple levels and included community partner buy-in and practitioners' motivation to implement PSE changes. CONCLUSIONS: Implementation strategies are needed to build on organizational strengths and to overcome multi-level barriers to PSE change implementation among LFCS practitioners. The results from the in-depth contextual inquiry used could serve as a guide for future pragmatic assessment efforts among other state Extension systems or as a model for identifying barriers and facilitators and associated implementation strategies among other public health systems in the U.S. and abroad.

Designing an Efficient Implementation Process for Large Scale Adoption of Telehealth.

Telehealth may be one of the solutions to the increasing demand of healthcare. However, implementation of such systems is a considerable effort, and requires an efficient and systemized process for large scale adoption. This study provides a process for telehealth implementation. Although quantitative studies of implementation processes introduce significant challenges, the study provide initial indications of increasing effectiveness, specifically in time to deployment.

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

BACKGROUND: The Expert Recommendations for Implementing Change (ERIC) project developed a compilation of implementation strategies that are intended to standardize reporting and evaluation. Little is known about the application of ERIC in low- and middle-income countries (LMICs). We systematically reviewed the literature on the use and specification of ERIC strategies for health intervention implementation in LMICs to identify gaps and inform future research. METHODS: We searched peer-reviewed articles published through March 2023 in any language that (1) were conducted in an LMIC and (2) cited seminal ERIC articles or (3) mentioned ERIC in the title or abstract. Two co-authors independently screened all titles, abstracts, and full-text articles, then abstracted study, intervention, and implementation strategy characteristics of included studies. RESULTS: The final sample included 60 studies describing research from all world regions, with over 30% published in the final year of our review period. Most studies took place in healthcare settings (n = 52, 86.7%), while 11 (18.2%) took place in community settings and four (6.7%) at the policy level. Across studies, 548 distinct implementation strategies were identified with a median of six strategies (range 1-46 strategies) included in each study. Most studies (n = 32, 53.3%) explicitly matched implementation strategies used for the ERIC compilation. Among those that did, 64 (87.3%) of the 73 ERIC strategies were represented. Many of the strategies not cited included those that target systems- or policy-level barriers. Nearly 85% of strategies included some component of strategy specification, though most only included specification of their action (75.2%), actor (57.3%), and action target (60.8%). A minority of studies employed randomized trials or high-quality quasi-experimental designs; only one study evaluated implementation strategy effectiveness. CONCLUSIONS: While ERIC use in LMICs is rapidly growing, its application has not been consistent nor commonly used to test strategy effectiveness. Research in LMICs must better specify strategies and evaluate their impact on outcomes. Moreover, strategies that are tested need to be better specified, so they may be compared across contexts. Finally, strategies targeting policy-, systems-, and community-level determinants should be further explored. TRIAL REGISTRATION: PROSPERO, CRD42021268374.

iCHECK-DH: Guidelines and Checklist for the Reporting on Digital Health Implementations.

BACKGROUND: Implementation of digital health technologies has grown rapidly, but many remain limited to pilot studies due to challenges, such as a lack of evidence or barriers to implementation. Overcoming these challenges requires learning from previous implementations and systematically documenting implementation processes to better understand the real-world impact of a technology and identify effective strategies for future implementation. OBJECTIVE: A group of global experts, facilitated by the Geneva Digital Health Hub, developed the Guidelines and Checklist for the Reporting on Digital Health Implementations (iCHECK-DH, pronounced "I checked") to improve the completeness of reporting on digital health implementations. METHODS: A guideline development group was convened to define key considerations and criteria for reporting on digital health implementations. To ensure the practicality and effectiveness of the checklist, it was pilot-tested by applying it to several real-world digital health implementations, and adjustments were made based on the feedback received. The guiding principle for the development of iCHECK-DH was to identify the minimum set of information needed to comprehensively define a digital health implementation, to support the identification of key factors for success and failure, and to enable others to replicate it in different settings. RESULTS: The result was a 20-item checklist with detailed explanations and examples in this paper. The authors anticipate that widespread adoption will standardize the quality of reporting and, indirectly, improve implementation standards and best practices. CONCLUSIONS: Guidelines for reporting on digital health implementations are important to ensure the accuracy, completeness, and consistency of reported information. This allows for meaningful comparison and evaluation of results, transparency, and accountability and informs stakeholder decision-making. i-CHECK-DH facilitates standardization of the way information is collected and reported, improving systematic documentation and knowledge transfer that can lead to the development of more effective digital health interventions and better health outcomes.

Measurement Characteristics of the Wraparound Fidelity Index Short Form: Results from a Statewide Implementation.

Implementation fidelity has been an important issue in the service provision and associated outcomes of Wraparound, an intensive, individualized care planning process that uses a team-based approach to integrate youth into the community to minimize the need for intensive, institutional services. In response to the growing need to monitor fidelity to the Wraparound process, a variety of instruments have been created and tested. In this study, the authors present the results of several analyses designed to better understand the measurement characteristics of the Wraparound Fidelity Index Short Form (WFI-EZ), a multi-informant fidelity instrument. The results from our analysis of 1027 WFI-EZ responses indicate that the internal consistency of the instrument is very good, although the negatively worded items did not appear to function as well as positively worded items. Results from two confirmatory factor analyses were unable to validate the original domains identified by the instrument developers, but for certain outcomes the WFI-EZ demonstrated deseriable predictive validity. Preliminary evidence is also provided that WFI-EZ responses likely differ by respondent type. We conclude by discussing the implications of using the WFI-EZ in programming, policy, and practice considering the findings of our study.

On-the-Go Adaptation of Implementation Approaches and Strategies in Health: Emerging Perspectives and Research Opportunities.

In many cases, implementation approaches (composed of one or more strategies) may need to change over time to work optimally. We use a literature review to inform a mechanistic analysis of such on-the-go adaptations. We suggest that such adaptations of implementation strategies consist of three necessary steps. The first component is the initial effect of the implementation approach on intended implementation, service delivery, or clinical outcomes. Second, these initial effects must in turn be used to modify, alter, intensify, or otherwise change the implementation approach. Third, the modified approach itself has effects. Conceiving of adaptation as all three steps implies that a full understanding of adaptation involves (a) a sense of initial effects, (b) conceptualizing and documenting content and rationale for changes in approach (e.g., alteration, intensification), and (c) the effects of the changed approach (including how the latter effects depend on initial effects). Conceptualizing these steps can help researchers ask questions about adaptation (e.g., thresholds for change, dosing, potentiation, sequencing) to advance our understanding of implementation strategies.

Adesão, barreiras e facilitadores no tratamento de hipertensão arterial: revisão rápida de evidências

[RESUMO]. Objetivo. Identificar estratégias para aumentar a adesão ao tratamento de hipertensão arterial sistêmica (HAS) e descrever as barreiras e os facilitadores para implementação dessas estratégias na atenção primária à saúde (APS). Métodos. Foi realizada uma revisão rápida de evidências. Foram incluídas revisões sistemáticas, com ou sem metanálises, publicadas em inglês, espanhol ou português, que avaliaram adultos (18 a ≤ 60 anos) com HAS acompanhados na APS. As buscas foram realizadas em nove bases de dados em dezembro de 2020 e atuali- zadas em abril de 2022. As revisões sistemáticas incluídas foram avaliadas quanto à qualidade metodológica por meio da ferramenta AMSTAR 2. Resultados. Foram incluídas 14 revisões sistemáticas sobre estratégias de adesão ao tratamento e três sobre barreiras e facilitadores para implementação. A qualidade metodológica foi moderada em uma revisão sistemática, baixa em quatro e criticamente baixa nas demais. Quatro estratégias foram identificadas como opções para políticas de saúde: ações realizadas por farmacêuticos; ações realizadas por profissionais não farmacêuticos; automonitoramento, uso de aplicativos de celular e mensagens de texto; e oferta de subsídios para aquisição de medicamentos. O baixo letramento digital, o acesso limitado à internet, processos de tra- balho e formação incipiente foram barreiras para os profissionais. Foram facilitadores o nível educacional e de letramento em saúde dos usuários, a acessibilidade aos serviços de saúde e o bom relacionamento com os profissionais. Conclusões. Identificaram-se efeitos positivos de estratégias relacionadas à atenção farmacêutica, automo- nitoramento e uso de aplicativos de celular e mensagem de texto para aumentar a adesão ao tratamento da HAS no âmbito da APS. Porém, para fins de implementação, é preciso considerar barreiras e facilitadores, além das limitações metodológicas das revisões sistemáticas analisadas.

[ABSTRACT]. Objective. To identify strategies to increase adherence to systemic arterial hypertension (SAH) treatment and describe the barriers and facilitators for implementing these strategies in primary health care (PHC). Method. A rapid evidence review was performed. We included systematic reviews with or without meta-analy- ses, published in English, Spanish or Portuguese, covering adults (age 18 to ≤ 60 years) with SAH followed in the PHC. Searches were performed in nine databases in December 2020 and updated in April 2022. The systematic reviews were assessed for methodological quality using the AMSTAR 2 tool. Results. Fourteen systematic reviews on treatment adherence strategies and three on barriers and facilitators for implementation were included. Regarding methodological quality, one systematic review was classified as moderate, four as low, and the others as critically low. Four strategies were identified as options for health policies: actions performed by pharmacists; actions performed by non-pharmaceutical health professionals; self-monitoring, use of mobile apps, and text messages; and subsidies for the purchase of medicines. Low digital literacy, limited access to the internet, work process and incipient training were barriers for professio- nals. The users' educational and health literacy levels, accessibility to health services and good relationships with professionals were facilitators. Conclusions. Positive effects of strategies related to pharmaceutical care, self-monitoring, and the use of cell phone applications and text messages were identified to increase adherence to the treatment of SAH in the context of PHC. However, for implementation purposes, it is necessary to consider barriers and facilitators, in addition to the methodological limitations of the analyzed systematic reviews.

[RESUMEN]. Objetivo. Buscar estrategias para aumentar la adhesión al tratamiento de la hipertensión arterial sistémica y describir las barreras y los elementos facilitadores para la implementación de esas estrategias en el ámbito de la atención primaria de salud. Métodos. Se realizó una revisión rápida de la evidencia. Se incluyeron revisiones sistemáticas, con o sin metaanálisis, publicadas en español, inglés o portugués, en las cuales se evaluaban a personas adultas (de 18 a ≤ 60 años) con hipertensión arterial sistémica observadas en el ámbito de la atención primaria de salud. Las búsquedas se realizaron en nueve bases de datos en diciembre del 2020 y se actualizaron en abril del 2022. Se evaluó la calidad metodológica de las revisiones sistemáticas incluidas con la herramienta AMSTAR 2. Resultados. Se incluyeron 14 revisiones sistemáticas sobre estrategias de adhesión al tratamiento y tres sobre obstáculos y elementos facilitadores para la implementación. La calidad metodológica fue moderada en una revisión sistemática, baja en cuatro y críticamente baja en las demás. Se identificaron cuatro estra- tegias como opciones para las políticas de salud: medidas tomadas por farmacéuticos; medidas tomadas por profesionales no farmacéuticos; autocontrol, uso de aplicaciones para teléfonos celulares y mensajes de texto; y oferta de subvenciones para la compra de medicamentos. La escasa alfabetización digital, el acceso limitado a internet y los procesos de trabajo y formación incipiente fueron obstáculos para los profesionales. Los elementos facilitadores fueron el nivel de educación y de conocimientos de los usuarios en materia de salud, la accesibilidad a los servicios de salud y las buenas relaciones con los profesionales. Conclusiones. Se observaron efectos positivos de las estrategias relacionadas con la atención farmacéutica, el autocontrol y el uso de aplicaciones de telefonía celular y mensajería de texto para aumentar la adhesión al tratamiento de la hipertensión arterial sistémica en el ámbito de la atención primaria de salud. Sin embargo, para fines de implementación, es necesario considerar los obstáculos y los elementos facilitadores, además de las limitaciones metodológicas de las revisiones sistemáticas analizadas.

Local public health projectification in practice: a qualitative study of facilitators and barriers to a public health plan implementation.

AIMS: To identify factors perceived by local government employees to affect the implementation of a municipal public health plan. METHODS: Qualitative individual interviews (n=13) were carried out. Participants were sampled from three districts in Oslo municipality, Norway, and asked about their experiences with an ongoing implementation of the Oslo Public Health Plan (2017-2020). The conceptual framework of public sector projectification - a growing reliance on project organisation of policies - informed the study. The consolidated framework for implementation research was used to aid data coding and subsequent thematic analysis. RESULTS: Implementation facilitators included factors perceived to support flexibility, including plan adaptability to the local setting, and factors perceived to enable structure and control during the implementation process, such as the articulation of specific goals and a shared understanding of public health work. Barriers were mainly related to complex aspects of the plan, such as the need to involve multiple stakeholders and levels of governance, and to tensions between the time-limited implementation process and the permanent organisational structures. CONCLUSIONS: This study has demonstrated how research-based methods can be used for the evaluation of a local community implementation process. It has identified implementation determinants using a predetermined taxonomy of operationally defined factors that are likely to influence implementation. However, while implementing a time-limited public health plan can be seen as 'taking action' in relation to multidimensional and complex problems, further research is needed to investigate whether plan implementation has a long-term impact on the surrounding organisation and, eventually, on public health outcomes.
