Supporting implementation of interventions to address ethnicity-related health inequities: frameworks, facilitators and barriers - a scoping review protocol

Inequality and health: Can medical practice address the consequences of inequalities?

BACKGROUND

The extent to which governments provide socioeconomic supports has been highlighted by their spending during the COVID-19 pandemic. This has implications for patterns of inequality, in particular on exacerbating unequal health and well-being.

RESULTS

Inequity has expanded due to neoliberalism, a market-based approach that has endured for more than four decades. Together with COVID-19, it has developed and exposed many structural governance differences.

DISCUSSION

There are a number of examples presented of the effects of inequalities on health and well-being. The role of general practice in addressing these is discussed and challenges are highlighted, especially those relating to payment systems and workforce constraints.

Adapting an equity-focused implementation process framework with a focus on ethnic health inequities in the Aotearoa New Zealand context

BACKGROUND

Health intervention implementation in Aotearoa New Zealand (NZ), as in many countries globally, usually varies by ethnicity. Māori (the Indigenous peoples of Aotearoa) and Pacific peoples are less likely to receive interventions than other ethnic groups, despite experiencing persistent health inequities. This study aimed to develop an equity-focused implementation framework, appropriate for the Aotearoa NZ context, to support the planning and delivery of equitable implementation pathways for health interventions, with the intention of achieving equitable outcomes for Māori, as well as people originating from the Pacific Islands.

METHODS

A scoping review of the literature to identify existing equity-focused implementation theories, models and frameworks was undertaken. One of these, the Equity-based framework for Implementation Research (EquIR), was selected for adaptation. The adaptation process was undertaken in collaboration with the project's Māori and consumer advisory groups and informed by the expertise of local health equity researchers and stakeholders, as well as the international implementation science literature.

RESULTS

The adapted framework's foundation is the principles of Te Tiriti o Waitangi (the written agreement between Māori rangatira (chiefs) and the British Crown), and its focus is whānau (extended family)-centred implementation that meets the health and wellbeing aspirations, priorities and needs of whānau. The implementation pathway comprises four main steps: implementation planning, pathway design, monitoring, and outcomes and evaluation, all with an equity focus. The pathway is underpinned by the core constructs of equitable implementation in Aotearoa NZ: collaborative design, anti-racism, Māori and priority population expertise, cultural safety and values-based. Additionally, the contextual factors impacting implementation, i.e. the social, economic, commercial and political determinants of health, are included.

CONCLUSIONS

The framework presented in this study is the first equity-focused process-type implementation framework to be adapted for the Aotearoa NZ context. This framework is intended to support and facilitate equity-focused implementation research and health intervention implementation by mainstream health services.

A scoping review of equity-focused implementation theories, models and frameworks in healthcare and their application in addressing ethnicity-related health inequities

BACKGROUND

Inequities in implementation contribute to the unequal benefit of health interventions between groups of people with differing levels of advantage in society. Implementation science theories, models and frameworks (TMFs) provide a theoretical basis for understanding the multi-level factors that influence implementation outcomes and are used to guide implementation processes. This study aimed to identify and analyse TMFs that have an equity focus or have been used to implement interventions in populations who experience ethnicity or 'race'-related health inequities.

METHODS

A scoping review was conducted to identify the relevant literature published from January 2011 to April 2022 by searching electronic databases (MEDLINE and CINAHL), the Dissemination and Implementation model database, hand-searching key journals and searching the reference lists and citations of studies that met the inclusion criteria. Titles, abstracts and full-text articles were screened independently by at least two researchers. Data were extracted from studies meeting the inclusion criteria, including the study characteristics, TMF description and operationalisation. TMFs were categorised as determinant frameworks, classic theories, implementation theories, process models and evaluation frameworks according to their overarching aim and described with respect to how equity and system-level factors influencing implementation were incorporated.

RESULTS

Database searches yielded 610 results, 70 of which were eligible for full-text review, and 18 met the inclusion criteria. A further eight publications were identified from additional sources. In total, 26 papers describing 15 TMFs and their operationalisation were included. Categorisation resulted in four determinant frameworks, one implementation theory, six process models and three evaluation frameworks. One framework included elements of determinant, process and evaluation TMFs and was therefore classified as a 'hybrid' framework. TMFs varied in their equity and systems focus. Twelve TMFs had an equity focus and three were established TMFs applied in an equity context. All TMFs at least partially considered systems-level factors, with five fully considering macro-, meso- and micro-level influences on equity and implementation.

CONCLUSIONS

This scoping review identifies and summarises the implementation science TMFs available to support equity-focused implementation. This review may be used as a resource to guide TMF selection and illustrate how TMFs have been utilised in equity-focused implementation activities.
