Identifying evidence for five realist reviews in primary health care: A comparison of search methods

Family participation in dignity interventions for patients with cancer receiving palliative care: a scoping review protocol

INTRODUCTION

The global burden of cancer is escalating, with Asia accounting for over half of cancer-related deaths worldwide. As cancer often diminishes patients' quality of life and sense of dignity, dignity-related interventions have gained prominence in palliative care for patients with cancer. However, a more in-depth exploration of the involvement of families, as the fundamental social units in Confucian Asian cultures, and cultural considerations is currently lacking. This scoping review focuses specifically on patients with cancer receiving palliative care and aims to offer a comprehensive synthesis of the existing evidence on family participatory dignity interventions, addressing the need for a holistic understanding of this emerging field to guide future research and clinical practice.

METHODS AND ANALYSIS

This scoping review will be meticulously structured according to the five-stage framework established by Arksey and O'Malley, complemented by the scoping review methodology of the Joanna Briggs Institute. Our search will encompass a comprehensive array of databases, including PubMed, Embase, The Cochrane Library, CINAHL, Web of Science, PsycINFO, Scopus, CNKI and Wanfang Data, from their inception up to August 2024, targeting both English and Chinese relevant literature. To ensure a thorough exploration, we will also delve into grey literature via OpenGrey, Google Scholar and citation chaining. This scoping review will include all types of quantitative or mixed methods designs and qualitative studies. We will extract data on study design, sample size, intervention details, outcome measures and any other relevant information. The screening process will be conducted by two independent reviewers, who will meticulously assess the titles and abstracts, followed by a full-text review to select relevant studies. Discrepancies will be resolved through consensus discussions with a third reviewer. Data extraction will be executed using a standardised tool, and the findings will be systematically presented in tabular form with an accompanying narrative to summarise all relevant interventions, their characteristics, outcomes and key findings.

ETHICS AND DISSEMINATION

Ethical approval for this scoping review is not required, since the methodology merely involves the collection and review of publicly available literature. Our findings will not only be presented and discussed in a peer-reviewed article but also shared at conferences relevant to the topic.

TRIAL REGISTRATION

Our scoping review protocol has been formally registered with the Open Science Framework. Registration details can be accessed at the provided link: https://osf.io/fyhrm/.

Community Group-Based Physical Activity Programs for Immigrant Older Adults: A Systematic Realist Review

Physical activity program interventions often lack sensitivity to the needs of older immigrant adults. The objective of this systematic realist review is to explain how, why, for whom, and under which circumstances community group-based physical activity programs work for immigrant older adults. The initial program theory was developed using prior research, team expertise, social cognitive theory, and knowledge user consultations. The program theory was tested and refined via a systematic review of the literature. Database searches were conducted in MEDLINE, EMBASE, CINAHL, Scopus, Cochrane Library, Sports Medicine and Education Index, and SPORTDiscus. A total of 22 sources of evidence met inclusion criteria and included intervention studies, systematic reviews, and a discussion paper. Intervention studies were appraised using the Mixed Methods Appraisal Tool. The final program theory constituted eight context-mechanism-outcome configurations that highlight the importance of facilitator characteristics, access to safe spaces, group dynamics, and social support. A limitation was the small number and variable quality of included evidence. Physical activity programs that target immigrant older adults must strengthen physical and psychological safety and maximize opportunities for role modeling and socialization. This research was supported by the Alberta Health Services Seniors Health Strategic Clinical Network and is registered in PROSPERO (ID#258179).

How does interprofessional education affect attitudes towards interprofessional collaboration? A rapid realist synthesis

Interprofessional collaboration (IPC) in healthcare is regarded as important by professionals, as it increases the quality of care while decreasing costs. Interprofessional education (IPE) is a prerequisite for IPC and influences learners' attitudes, knowledge, and collaboration skills. Since attitudes shape behavior, understanding how they are formed is crucial for influencing IPC in learners' professional practice. We investigated what kind of IPE works, for which students, how, and in what circumstances to develop positive attitudes towards IPC. Using realist synthesis, we extracted causal mechanisms that produce positive attitude outcomes and the conducive contexts that trigger them. Our analysis resulted in six plausible context-mechanism-outcome configurations that explain positive attitude development. Positive IPC attitudes are more likely to arise in contexts where IPE provides time and facilities for formal and informal interactions, as this allows learners to get to know each other both professionally and personally, fostering trust, respect, and mutual liking. Additionally, positive attitudes are more likely in contexts where the IPE curriculum is perceived as career-relevant and boosts confidence. Key mechanisms of positive attitude development include getting to know the other learners professionally and personally, experiencing positive affect during IPE, and learners experiencing mutual dependence. Sustained positive attitudes are more likely to develop when there is organizational support for IPC and professionals attend IPE on an ongoing basis, allowing the attitudes and values expected in IPC to be positively reinforced and eventually integrated into the learners' personal value system.

A realist review of the causes of, and current interventions to address 'missingness' in health care

Background

This protocol describes a realist review exploring the problem of "missingness" in healthcare, defined as the repeated tendency not to take up offers of care that has a negative impact on the person and their life chances. More specifically, the review looks at the phenomenon of patients missing multiple appointments in primary care in the UK - at the causal factors that influence how patients come to be "missing" in this way, and what interventions might support uptake and "presence" in healthcare. Background research informing this project suggests that a high rate of missed appointments predicted high premature death rates, and patients were more likely to have multiple long-term health conditions and experience significant socioeconomic disadvantage. Most research in this field focuses on population- or service-level characteristics of patients who miss appointments, often making no distinction between causes of single missed appointments and of multiple missed appointments. There have therefore been no interventions for 'missingness', accounting for the complex life circumstances or common mechanisms that cause people to repeatedly miss appointments.

Methods

We use a realist review approach to explore what causes missingness - and what might prevent or address it - for whom, and in what circumstances. The review uses an iterative approach of database searching, citation-tracking and sourcing grey literature, with selected articles providing insight into the causal dynamics underpinning missed appointments and the interventions designed to address them.

Discussion

The findings of this review will be combined with the findings of a qualitative empirical study and the contributions of a Stakeholder Advisory Group (STAG) to inform the development of a programme theory that seeks to explain how missingness occurs, whom it affects and under what circumstances. This will be used to develop a complex intervention to address multiple missed appointments in primary care.

Developing an initial programme theory for a model of social care in prisons and on release (empowered together): A realist synthesis approach

Many people are living in prison with a range of social care needs, for example, requiring support with washing, eating, getting around safely, and/or maintaining relationships. However, social care for this vulnerable group is generally inadequate. There is uncertainty and confusion about who is legally responsible for this and how it can best be provided, and a lack of integration with healthcare. We used realist-informed approaches to develop an initial programme theory (IPT) for identifying/assessing social care needs of, and providing care to, male adults in prison and on release. IPT development was an iterative process involving (a) an initial scoping of the international prison literature; (b) scoping prison and community social care policy documents and guidelines; (c) full systematic search of the international prison social care literature; (d) insights from the community social care literature; (e) stakeholder workshops. Information from 189 documents/sources and stakeholder feedback informed the IPT, which recommended that models of prison social care should be: trauma-informed; well integrated with health, criminal justice, third-sector services and families; and person-centred involving service-users in all aspects including co-production of care plans, goals, and staff training/awareness programmes. Our IPT provides an initial gold standard model for social care provision for people in prison and on release. The model, named Empowered Together, will be evaluated in a future trial and will be of interest to those working in the criminal justice system, care providers and commissioners, local authorities, housing authorities, voluntary groups, and service-users and their families.

Screening and identification of fetal alcohol spectrum disorder in criminal legal settings: A realist review

BACKGROUND

Screening for fetal alcohol spectrum disorder (FASD) has been identified as a promising approach to improve recognition, understanding and effective response to the unique needs of those with FASD in criminal legal settings. However, to date, there has been limited synthesis of relevant screening tools, indicators, or implementation considerations in this context.

AIMS

The present review aimed to synthesise evidence and develop a conceptual framework for understanding how, when, why, for whom and by whom FASD screening tools, items and/or indicators and characteristics serve to accurately identify people with FASD in criminal legal contexts, with consideration of individual and system needs relevant to effective implementation and response.

METHODS

A preregistered search was conducted using a modified realist review framework for both peer-reviewed articles and grey literature. Included sources were available in English, which focused on individuals with prenatal alcohol exposure and/or FASD with criminal legal involvement and offered new empirical evidence. Sources were reviewed using the Quality Control Tool for Screening Titles and Abstracts by Second Reviewer framework, extracted using a structured coding form and narratively synthesised.

RESULTS

The search yielded 52 sources, 11 FASD screening tools designed for or applied in criminal legal settings and 38 potential FASD indicators or characteristics relevant to identifying people who may have FASD in criminal legal settings, organised into six conceptually related domains. There was limited evidence supporting the psychometric properties of screening tools across populations or settings, though growing evidence highlights the promise of some instruments. Although few studies characterised potential considerations to be made when implementing a screening tool or approach, both system and individual level needs related to recognising and effectively responding to FASD in criminal legal contexts were identified, and findings revealed strong support among legal and clinical professionals regarding the need for FASD screening in these settings.

CONCLUSIONS

Findings of this review can be used to inform the development, selection, implementation and evaluation of FASD screening tools in criminal legal settings and underscore a continued need for enhanced resources, policy and cross-sectoral response to better support the needs of people with FASD in the criminal legal contexts.

How, and under what contexts, do academic-practice partnerships collaborate to implement healthcare improvement education into preregistration nursing curriculums: a realist review protocol

INTRODUCTION

Internationally, healthcare improvement remains a clinical and educational priority. Consensus in Europe, Canada and the USA to implement quality improvement (QI) education into preregistration nursing curricula ensures students become equipped with the skills and knowledge required to improve practice. Now, New Zealand and Australia are beginning to implement QI education into their nursing curricula. However, QI education is complex; comprising multiple components, each influenced by the contexts under which they are developed and implemented. Evaluation studies of QI education unanimously acknowledge that academic and practice partnerships (APPs) are essential to optimally embed QI into preregistration curricula, yet it is not understood how, and under what contexts, APPs collaborate to achieve this.

METHODS AND ANALYSIS

A realist review to determine how, and under what contexts, APPs collaborate to implement QI education in pre-registration nursing will be conducted using the Realist and Meta-narrative Evidence Syntheses: Evolving Standards Guidelines. International stakeholders will be consulted at each stage which includes (1) clarifying the scope of the review through empirical literature and tacit expert knowledge, (2) searching for evidence in healthcare and social science databases/grey literature, (3) appraising studies using the Evidence for Policy and Practice Information and Co-ordinating Centre weight of evidence framework and extracting data using Standards for QUality Improvement Reporting Excellence in Education Publication Guidelines, (4) synthesising evidence and drawing conclusions through the creation of context, mechanism and outcome configurations and (5) disseminating findings through conferences and peer-reviewed publications.

ETHICS AND DISSEMINATION

Ethical approval was not required for this study. Findings will be disseminated to international nurse educators, leaders and front-line staff implementing QI education within their own academic and practice contexts through conferences and peer-reviewed publications.

Health effects of Indigenous language use and revitalization: a realist review

BACKGROUND

Indigenous populations across the world are more likely to suffer from poor health outcomes when compared to other racial and ethnic groups. Although these disparities have many sources, one protective factor that has become increasingly apparent is the continued use and/or revitalization of traditional Indigenous lifeways: Indigenous language in particular. This realist review is aimed at bringing together the literature that addresses effects of language use and revitalization on mental and physical health.

METHODS

Purposive bibliographic searches on Scopus were conducted to identify relevant publications, further augmented by forward citation chaining. Included publications (qualitative and quantitative) described health outcomes for groups of Indigenous people who either did or did not learn and/or use their ancestral language. The geographical area studied was restricted to the Americas, Australia or New Zealand. Publications that were not written in English, Spanish, French, Portuguese or German were excluded. A realist approach was followed to identify positive, neutral or negative effects of language use and/or acquisition on health, with both qualitative and quantitative measures considered.

RESULTS

The bibliographic search yielded a total of 3508 possible publications of which 130 publications were included in the realist analysis. The largest proportion of the outcomes addressed in the studies (62.1%) reported positive effects. Neutral outcomes accounted for 16.6% of the reported effects. Negative effects (21.4%) were often qualified by such issues as possible cultural use of tobacco, testing educational outcomes in a student's second language, and correlation with socioeconomic status (SES), health access, or social determinants of health; it is of note that the positive correlations with language use just as frequently occurred with these issues as the negative correlations did.

CONCLUSIONS

Language use and revitalization emerge as protective factors in the health of Indigenous populations. Benefits of language programs in tribal and other settings should be considered a cost-effective way of improving outcomes in multiple domains.

A Tailored Approach: A model for literature searching in complex systematic reviews

Our previous work identified that nine leading guidance documents for seven different types of systematic review advocated the same process of literature searching. We defined and illustrated this process and we named it ‘the Conventional Approach’. The Conventional Approach appears to meet the needs of researchers undertaking literature searches for systematic reviews of clinical interventions. In this article, we report a new and alternate process model of literature searching called ‘A Tailored Approach’. A Tailored Approach is indicated as a search process for complex reviews which do not focus on the evaluation of clinical interventions. The aims of this article are to (1) explain the rationale for, and the theories behind, the design of A Tailored Approach; (2) report the current conceptual illustration of A Tailored Approach and to describe a user’s interaction with the process model; and (3) situate the elements novel to A Tailored Approach (when compared with the Conventional Approach) in the relevant literature. A Tailored Approach suggests investing time at the start of a review, to develop the information needs from the research objectives, and to tailor the search approach to studies or data. Tailored Approaches should be led by the information specialist (librarian) but developed by the research team. The aim is not necessarily to focus on comprehensive retrieval. Further research is indicated to evaluate the use of supplementary search methods, methods of team-working to define search approaches, and to evaluate the use of conceptual models of information retrieval for testing and evaluation.
