Theoretical approaches to process evaluations of complex interventions in health care: a systematic scoping review protocol

Background: Complex interventions in health care are characterized by multiple interacting components as well as by numerous nonlinear interactions with the social systems within which they are being implemented. The process of developing, evaluating and implementing complex interventions is therefore challenging. Established guidance such as the MRC (Medical Research Council) framework for developing and evaluating complex interventions refers to process evaluations as an integral part of the development of complex evidence-based interventions. Even though the need for process evaluations is recognized, the realization of such approaches is challenging because methodological instruction is sparse, and the phenomenon of interest is complex. A number of theoretical approaches indicating how to conduct process evaluations of complex interventions in health care exist, but a systematic and comprehensive overview of these is missing. Thus, the objective of the systematic scoping review described herein is to provide an overview and analysis of theoretical approaches suitable for the planning and conducting of process evaluations. Methods: The design and conduct of this review will follow the procedures of a systematic scoping review. The search strategy will be developed following the BeHEMoTh (Behaviour of interest; Health context; Exclusions; Models or Theories) template which has been conceptualized for structured reviews of theory. The systematic search of the MEDLINE (via PubMed), CINAHL (via EBSCO) and PsycInfo (via EBSCO) electronic databases will be complemented by "hand searching" techniques. Study selection, data extraction, and data analysis will be performed by tandems of two researchers independently of each other. Divergent decisions and judgements between the two researchers will be discussed by the whole review team. Discussion: The findings from this scoping review will provide an overview and comparison of theoretical approaches suitable for process evaluations of complex interventions in health care. The review results will support researchers in choosing the theoretical approach that best fits the respective focus of their process evaluation study. Systematic review registration: This study has been registered with PROSPERO (International Prospective Register of Systematic Reviews) under registration number CRD42020211732 . Keywords: Complex intervention; Frameworks; Health care; Implementation; Models; Process evaluation; Systematic scoping review; Theory

Intersectionality and its relevance for research in dementia care of people with a migration background

BACKGROUND: Despite the care and support needs of migrants affected by dementia differing from the population of the country where they live now, most European countries do not provide specific strategies to address migration in their national dementia plans. The concept of intersectionality provides an innovative approach to dementia care perspectives and methodologies. OBJECTIVE: The aim is to define intersectionality and to provide examples of applying the concept to dementia care research, focusing on people with a migration background. METHODS: This article was conceptualized and discussed during virtual INTERDEM taskforce meetings in 2020/2021, while discussing identified literature on intersectionality, migration, and dementia care research. RESULTS: Using an intersectionality framework allows understanding of a person's lived experience by considering the dimensionality, co-occurrence and interlocking of factors (e.g., sex/gender, socioeconomic status, ethnicity, migration status, geographic location/place). CONCLUSION: Intersectionality can be applied as a conceptual and methodological approach to identify and address gaps in perspectives and in (dementia care) research to overcome the threat of ignorance, exclusion and discrimination

Dementia and COVID-19 in Chile, New Zealand and Germany: A Research Agenda for Cross-Country Learning for Resilience in Health Care Systems

The COVID-19 pandemic has revealed existing gaps in policies, systems and services, stressing the need for concerted global action on healthy aging. Similar to the COVID-19 pandemic, dementia is a challenge for health systems on a global scale. Our hypothesis is that translational potential lies in cross-country learning by involving three high-income countries with distinct geo-political-cultural-social systems in Latin America (Chile), the South Pacific (New Zealand) and Europe (Germany). Our vision is that such cross-country learning will lead to providing adequate, equitable and sustainable care and support for families living with dementia during a pandemic and beyond. We are proposing a vision for research that takes a multi-disciplinary, strength-based approach at the intersection of health care research, disaster research, global health research and dementia research. We present some insights in support of our hypothesis and proposed research agenda. We anticipate that this research has the potential to contribute towards strengthening and transforming health care systems in times of crises and beyond
