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

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.
