The "realist search": A systematic scoping review of current practice and reporting

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).

Optimising digital clinical consultations in maternity care: a realist review and implementation principles

OBJECTIVES

The COVID-19 pandemic has led to increased use of digital clinical consultations (phone or video calls) within UK maternity services. This project aimed to review the evidence on digital clinical consultations in maternity systems to illuminate how, for whom and in what contexts, they can be used to support safe, personalised and equitable care.

DESIGN

A realist synthesis, drawing on diverse sources of evidence (2010-present) from OECD countries, alongside insights from knowledge user groups (representing healthcare providers and service users).

METHODS

The review used three analytical processes (induction, abduction and retroduction) within three iterative stages (development of initial programme theories; evidence retrieval and synthesis; validation and refinement of the programme theories).

RESULTS

Ninety-three evidence sources were included in the final synthesis. Fifteen programme theories were developed showing that digital clinical consultations involve different mechanisms operating across five key contexts: the organisation, healthcare providers, the clinical relationship, the reason for consultation and women. The review suggests that digital clinical consultations can be effective and acceptable to stakeholders if there is access to appropriate infrastructure/digital resources and if implementation is able to ensure personalisation, informed choice, professional autonomy and relationship-focused connections. The review found relatively less evidence in relation to safety and equity.

CONCLUSIONS

Due to the complexity of maternity systems, there can be 'no one-size fits all' approach to digital clinical consultations. Nonetheless, the review distills four 'CORE' implementation principles: C-creating the right environment, infrastructure and support for staff; O-optimising consultations to be responsive, flexible and personalised to different needs and preferences; R-recognising the importance of access and inclusion; and E-enabling quality and safety through relationship-focused connections. Service innovation and research are needed to operationalise, explore and evaluate these principles, particularly in relation to safety and equity.

Strategies for older people living in care homes to prevent urinary tract infection: the StOP UTI realist synthesis

Background

Urinary tract infection is the most diagnosed infection in older people. It accounts for more than 50% of antibiotic prescriptions in care homes and is a frequent reason for care home residents being hospitalised.

Objective

This realist review developed and refined programme theories for preventing and recognising urinary tract infection, exploring what works, for whom and in what circumstances.

Design

The review used realist synthesis to explore existing literature on the detection and prevention of urinary tract infection, complemented by stakeholder consultation. It applies to the UK context, although other healthcare systems may identify synergies in our findings.

Data sources

Bibliographic databases searched included MEDLINE, CINAHL, EMBASE, Cochrane Library, Web of Science Core Collection (including the Social Sciences Citation Index), Sociological Abstracts, Bibliomap and National Institute for Health and Care Research Journals Library.

Data selection and extraction

Title and abstract screening were undertaken by two researchers independently of each other. Selection and assessment were based on relevance and rigour and cross-checked by a second researcher. Data extracted from the included studies were explored for explanations about how the interventions were considered to work (or not). Evidence tables were constructed to enable identification of patterns across studies that offered insight about the features of successful interventions.

Data analysis and synthesis

Programme theories were constructed through a four-stage process involving scoping workshops, examination of relevant extant theory, analysis and synthesis of primary research, teacher-learner interviews and a cross-system stakeholder event. A process of abductive and retroductive reasoning was used to construct context-mechanism-outcome configurations to inform programme theory.

Results

The scoping review and stakeholder engagement identified three theory areas that address the prevention and recognition of urinary tract infection and show what is needed to implement best practice. Nine context-mechanism-outcome configurations provided an explanation of how interventions to prevent and recognise urinary tract infection might work in care homes. These were (1) recognition of urinary tract infection is informed by skills in clinical reasoning, (2) decision-support tools enable a whole care team approach to communication, (3) active monitoring is recognised as a legitimate care routine, (4) hydration is recognised as a care priority for all residents, (5) systems are in place to drive action that helps residents to drink more, (6) good infection prevention practice is applied to indwelling urinary catheters, (7) proactive strategies are in place to prevent recurrent urinary tract infection, (8) care home leadership and culture fosters safe fundamental care and (9) developing knowledgeable care teams.

Limitations

We adapted our approach and work to online interactions with stakeholders and as a research team because of COVID-19. This also had an impact on bringing stakeholders together at a face-to-face event at the end of the project. Studies focusing on the prevention of urinary tract infection in care home settings were predominantly from the USA and Europe where the regulatory and funding systems for the long-term care of the elderly have some differences, particularly in the USA where national reporting plays a significant role in driving improvements in care.

Conclusions

Care home staff have a vital role in the prevention and recognition of urinary tract infection, which can be enabled through integration and prioritisation within the systems and routines of care homes and delivery of person-centred care. Promoting fundamental care as a means of facilitating a holistic approach to prevention and recognition of urinary tract infection helps staff to recognise how they can contribute to antimicrobial stewardship and recognition of sepsis. Challenging assumptions made by staff about the presentation of urinary tract infection is complex and requires education that facilitates 'unlearning' and questioning of low-value practices. Programmes to prevent urinary tract infection need to be co-designed and supported through active and visible leadership by care home managers with support from specialist practitioners.

Future work

We will focus on co-designing tools that facilitate implementation of our findings to ensure they fit with the care home context and address some of the challenges faced by care home leaders. This will underpin action at care home and system levels. Further research is needed to better understand the perspectives of residents and family carers, the effectiveness of non-pharmacological, pharmacological and specialist practitioner interventions and non-traditional approaches to training and educating the workforce in care home settings.

Why do acute healthcare staff behave unprofessionally towards each other and how can these behaviours be reduced? A realist review

Background

Unprofessional behaviour in healthcare systems can negatively impact staff well-being, patient safety and organisational costs. Unprofessional behaviour encompasses a range of behaviours, including incivility, microaggressions, harassment and bullying. Despite efforts to combat unprofessional behaviour in healthcare settings, it remains prevalent. Interventions to reduce unprofessional behaviour in health care have been conducted - but how and why they may work is unclear. Given the complexity of the issue, a realist review methodology is an ideal approach to examining unprofessional behaviour in healthcare systems.

Aim

To improve context-specific understanding of how, why and in what circumstances unprofessional behaviours between staff in acute healthcare settings occur and evidence of strategies implemented to mitigate, manage and prevent them.

Methods

Realist synthesis methodology consistent with realist and meta-narrative evidence syntheses: evolving standards reporting guidelines.

Data sources

Literature sources for building initial theories were identified from the original proposal and from informal searches of various websites. For theory refinement, we conducted systematic and purposive searches for peer-reviewed literature on databases such as EMBASE, Cumulative Index to Nursing and Allied Health Literature and MEDLINE databases as well as for grey literature. Searches were conducted iteratively from November 2021 to December 2022.

Results

Initial theory-building drew on 38 sources. Searches resulted in 2878 titles and abstracts. In total, 148 sources were included in the review. Terminology and definitions used for unprofessional behaviours were inconsistent. This may present issues for policy and practice when trying to identify and address unprofessional behaviour. Contributors of unprofessional behaviour can be categorised into four areas: (1) workplace disempowerment, (2) organisational uncertainty, confusion and stress, (3) (lack of) social cohesion and (4) enablement of harmful cultures that tolerate unprofessional behaviours. Those at most risk of experiencing unprofessional behaviour are staff from a minoritised background. We identified 42 interventions in the literature to address unprofessional behaviour. These spanned five types: (1) single session (i.e. one-off), (2) multiple sessions, (3) single or multiple sessions combined with other actions (e.g. training session plus a code of conduct), (4) professional accountability and reporting interventions and (5) structured culture-change interventions. We identified 42 reports of interventions, with none conducted in the United Kingdom. Of these, 29 interventions were evaluated, with the majority (n = 23) reporting some measure of effectiveness. Interventions drew on 13 types of behaviour-change strategy designed to, for example: change social norms, improve awareness of unprofessional behaviour, or redesign the workplace. Interventions were impacted by 12 key dynamics, including focusing on individuals, lack of trust in management and non-existent logic models.

Conclusions

Workplace disempowerment and organisational barriers are primary contributors to unprofessional behaviour. However, interventions predominantly focus on individual education or training without addressing systemic, organisational issues. Effectiveness of interventions to improve staff well-being or patient safety is uncertain. We provide 12 key dynamics and 15 implementation principles to guide organisations.

Future work

Interventions need to: (1) be tested in a United Kingdom context, (2) draw on behavioural science principles and (3) target systemic, organisational issues.

Limitations

This review focuses on interpersonal staff-to-staff unprofessional behaviour, in acute healthcare settings only and does not include non-intervention literature outside the United Kingdom or outside of health care.

Expert searchers identified time, team, technology and tension as challenges when carrying out supplementary searches for systematic reviews: A thematic network analysis

BACKGROUND

Systematic reviews require detailed planning of complex processes which can present logistical challenges. Understanding these logistical challenges can help with planning and execution of tasks OBJECTIVES: To describe the perspectives of expert searchers on the main logistical challenges when carrying out supplementary searches for systematic reviews, in particular, forward citation searching and web searching.

METHODS

Qualitative interviews were undertaken with 15 experts on searching for studies for systematic reviews (e.g. information specialists) working in health and social care research settings. Interviews were undertaken by video-call between September 2020 and June 2021. Data analysis used thematic network analysis.

RESULTS

We identified three logistical challenges of using forward citation searching and web searching which were organised under the global theme of 'tension': time, team and technology. Several subthemes were identified which supported the organising themes, including allocating time, justifying time and keeping to time; reviewer expectations and contact with review teams; and access to resources and reference management.

CONCLUSION

Forward citation searching and web searching are logistically challenging search methods for a systematic review. An understanding of these challenges should encourage expert searchers and review teams to maintain open channels of communication, which should also facilitate improved working relationships.

Investigating the Implementation of Community-Based Stroke Telerehabilitation in England; A Realist Synthesis Study Protocol

Telerehabilitation (TR) shows promise as a method of remote service delivery, yet there is little guidance to inform implementation in the context of the National Health Service (NHS) in England. This paper presents the protocol for a realist synthesis study aiming to investigate how TR can be implemented to support the provision of high-quality, equitable community-based stroke rehabilitation, and under what conditions. Using a realist approach, we will synthesise information from (1) an evidence review, (2) qualitative interviews with clinicians (n ≤ 30), and patient-family carer dyads (n ≤ 60) from three purposively selected community stroke rehabilitation services in England. Working groups including rehabilitation professionals, service-users and policy-makers will co-develop actionable recommendations. Insights from the review and the interviews will be synthesised to test and refine programme theories that explain how TR works and for whom in clinical practice, and draw key messages for service implementation. This protocol highlights the need to improve our understanding of TR implementation in the context of multidisciplinary, community-based stroke service provision. We suggest the use of a realist methodology and co-production to inform evidence-based recommendations that consider the needs and priorities of clinicians and people affected by stroke.

Workplace interventions to prevent suicide: A scoping review

OBJECTIVES

To map organisational interventions for workplace suicide prevention, identifying the effects, mechanisms, moderators, implementation and economic costs, and how interventions are evaluated.

BACKGROUND

Suicide is a devastating event that can have a profound and lasting impact on the individuals and families affected, with the highest rates found among adults of work age. Employers have a legal and ethical responsibility to provide a safe working environment for their employees, which includes addressing the issue of suicide and promoting mental health and well-being.

METHODS

A realist perspective was taken, to identify within organisational suicide prevention interventions, what works, for whom and in what circumstances. Published and unpublished studies in six databases were searched. To extract and map data on the interventions the Effect, Mechanism, Moderator, Implementation, Economic (EMMIE) framework was used. Mechanisms were deductively analysed against Bronfenbrenner's socio-ecological model.

RESULTS

From 3187 records screened, 46 papers describing 36 interventions within the military, healthcare, the construction industry, emergency services, office workers, veterinary surgeons, the energy sector and higher education. Most mechanisms were aimed at the individual's immediate environment, with the most common being education or training on recognising signs of stress, suicidality or mental illness in oneself. Studies examined the effectiveness of interventions in terms of suicide rates, suicidality or symptoms of mental illness, and changes in perceptions, attitudes or beliefs, with most reporting positive results. Few studies reported economic costs but those that did suggested that the interventions are cost-effective.

CONCLUSIONS

It seems likely that organisational suicide prevention programmes can have a positive impact on attitudes and beliefs towards suicide as well reducing the risk of suicide. Education, to support individuals to recognise the signs and symptoms of stress, mental ill health and suicidality in both themselves and others, is likely to be an effective starting point for successful interventions.

Communication partner training for student health and social care professionals engaging with people with stroke acquired communication difficulties: A protocol for a realist review

Background

Stroke acquired communication impairments impede effective communication. Consequently, in stroke care, communicative interactions can be challenging for both patients and staff and can predispose patients to increased risk of preventable adverse events. Communication partner training (CPT) can mitigate such negative outcomes by optimising communicative interactions. Providing CPT to student health and social care professionals (SH&SCPs) has the potential to enhance their clinical expertise and experiences and enhance the future clinical care of patients with stroke acquired communication impairments. This research aims to expand our understanding of how CPT is operationalised for SH&SCPs in higher education institutions and determine: what works; for whom; in what contexts; how and why?

Methods

This review is Phase 1 of a research project employing a realist approach with public and patient involvement (PPI). It incorporates five iterative steps: 1.) Clarifying the scope; 2.) Searching for evidence; 3.) Selecting and appraising evidence; 4.) Data extraction; 5.) Synthesising data and developing a middle range theory explaining how CPT is expected to work for SH&SCPs. An advisory panel, including PPI advisors, content advisors, student advisors, realist advisors and educationalist advisor has been set up to consult throughout the review and collaboratively agree the middle range theory.

Discussion

While there is an evolving evidence base for CPT, including stroke specific CPT for SH&SCPs, it is acknowledged that there are challenges to its implementation in complex real-world settings. In combining empirical evidence with theoretical understanding, realist review permits synthesis of data from diverse sources and goes beyond determining efficacy to explore generative causation and solutions for real world practice. A middle range realist programme theory that coherently explains how CPT is expected to work when teaching SH&SCPs to communicate with people with stroke acquired communication impairments will provide educators with new insights into CPT development and implementation in their higher education institutions.

A realist synthesis of interprofessional patient safety activities and healthcare student attitudes towards patient safety

Interprofessional education (IPE) has been used for instilling a positive safety culture within healthcare, yet what interventions work to change healthcare student attitudes and how improved patient safety outcomes are best achieved with this intervention, is unclear and challenging to evaluate. A realist synthesis was undertaken to ascertain how, why, and in what circumstances IPE activities result in a positive change to student attitudes to patient safety. Database searches of CINAHL, MEDLINE, Scopus, and Eric were undertaken in April 2022 to identify relevant studies. Synthesis with a realist framework of analysis, coupled with the development of a program theory was conducted to identify interactions among contexts, intervention, mechanisms, and outcomes (CIMO). Twenty-three articles eligible for inclusion articulated environments in which varied contexts, interventions, and mechanisms were activated to influence student attitudes to patient safety. Findings from this realist synthesis informs awareness into the methods of delivering and evaluating IPE activities and offers new perspectives for educators in planning and evaluating future IPE from a collaborative and positive safety culture perspective.

Contexts, behavioural mechanisms and outcomes to optimise therapeutic exercise prescription for persistent low back pain: a realist review

OBJECTIVE

Therapeutic exercises are a core treatment for low back pain (LBP), but it is uncertain how rehabilitative exercise facilitates change in outcomes. Realist reviews explore how the context (C) of certain settings or populations and underlying mechanisms (M) create intended or unintended outcomes (O). Our objective was to explore and understand the behavioural mechanisms by which therapeutic exercise creates change in outcomes of adherence, engagement and clinical outcomes for patients with LBP.

METHODS

This was a realist review reported following the Realist and Meta-narrative Evidence Syntheses: Evolving Standards guidance. We developed initial programme theories, modified with input from a steering group (experts, n=5), stakeholder group (patients and clinicians, n=10) and a scoping search of the published literature (n=37). Subsequently, an information specialist designed and undertook an iterative search strategy, and we refined and tested CMO configurations.

RESULTS

Of 522 initial papers identified, 75 papers were included to modify and test CMO configurations. We found that the patient-clinician therapeutic consultation builds a foundation of trust and was associated with improved adherence, engagement and clinical outcomes, and that individualised exercise prescription increases motivation to adhere to exercise and thus also impacts clinical outcomes. Provision of support such as timely follow-up and supervision can further facilitate motivation and confidence to improve adherence to therapeutic exercises for LBP.

CONCLUSIONS

Engagement in and adherence to therapeutic exercises for LBP, as well as clinical outcomes, may be optimised using mechanisms of trust, motivation and confidence. These CMO configurations provide a deeper understanding of ways to optimise exercise prescription for patients with LBP.

Understanding how therapeutic exercise prescription changes outcomes important to patients with persistent non-specific low back pain: a realist review protocol

INTRODUCTION

Persistent low back pain (LBP) is the leading cause of disability worldwide, and therapeutic exercise is recommended as a first-line treatment in international guidelines. The effects of exercise on clinical outcomes of pain and physical function are small to moderate, despite broader impacts on cardiovascular systems, biological health, mood, and emotional well-being. Therapeutic exercise prescription is defined as exercise that is prescribed by a clinician for a health-related treatment. It is unknown how therapeutic exercise prescription creates effects on outcomes of importance. Realist reviews explore how underlying mechanisms (M) may be active in the context (C) of certain situations, settings, or populations to create an intended or unintended outcome (O). Our objective is to explore and understand the mechanisms by which therapeutic exercise prescription changes outcomes for people with persistent LBP.

METHODS

We will develop initial programme theories based on preliminary data from a previous systematic review and consensus workshop. These theories will be modified with input from a steering group (experts), a stakeholder group (people with lived experience of exercise for persistent LBP and clinicians), and a scoping search of the published literature. An information specialist will design and undertake an iterative search strategy. These will be used to create CMO configurations, which will be refined and tested using the literature. The realist review will be reported following RAMESES guidance.

DISCUSSION

Realist reviews are uncommon in LBP research to date, yet those offer an opportunity to contrast with traditional methods of randomised controlled trials and systematic reviews and provide additional information regarding the contexts and mechanisms that may trigger certain outcomes. This can aid our understanding of the contextual features that may influence exercise prescription, such as for whom they are most effective, in what setting, how they are implemented and why. This realist synthesis will enhance our understanding of therapeutic exercise prescription to improve adherence and engagement and ultimately will provide clinically relevant recommendations regarding exercise prescription for those with persistent LBP.

Green spaces and the impact on cognitive frailty: a scoping review

Some literature indicates that contact with green spaces can benefit health and wellbeing, but it is unclear whether this is protective of cognitive health in older people. Using Arskey and O'Malley's framework the aim was to investigate ageing, cognitive frailty and the effects of green access including any causality. The evidence was somewhat inconsistent but suggestive for a beneficial role of green space exposure on cognitive functions. Results suggested that globally, the poorer urban environments are high risk for older people's mental health and these places often lack parks and green spaces. There is evidence that the level of activity and social participation may be greater with access to green spaces and therefore reduces health risks. Green spaces seem to have a role in preventing cognitive frailty, especially for more vulnerable older populations living in poorer urban environments.

An introduction to realist evaluation and synthesis for kidney research

Realist research describes a methodological approach that aims to explore how and why interventions work, for whom, and under what circumstances. Rather than quantifying how well an intervention works under specific conditions, realist theory explores the function of interventions in detail and specifically considers how the contexts in which interventional components are delivered influence the mechanisms that lead to outcomes. Realist methods can be applied to primary data (realist evaluation) or secondary data (realist synthesis). Although realist techniques are increasingly being used in the evaluation of complex interventions, there are relatively few published studies in the field of kidney care. In this review, we outline the theory and principles behind realist methods through discussion of a published realist synthesis describing complex interventions promoting delivery of optimal chronic kidney disease care. We discuss other kidney studies that have used realist methodology and situations where realist techniques could be applied to advance our understanding of how to best deliver care to patients with kidney disease.

Mobile apps to self-manage chronic low back pain: A realist synthesis exploring what works, for whom and in what circumstances

Objective

Chronic low back pain places a significant burden on healthcare services and sufferers. Clinical guidelines state that it is a condition that requires self-management. This realist synthesis explores how a mobile app could help people to self-manage chronic low back pain.

Method

Six databases and several non-academic sources were searched. In addition, nineteen realist interviews were conducted with stakeholders. Sources were selected and appraised for relevancy, richness, and rigour. Data was coded with analytical memos making retroductive inferences. Causal explanations were presented in context-mechanism-outcome configurations to form three programme theories.

Results

Data from 57 sources was synthesised to create 16 context-mechanism-outcome configurations and presented as three refined programme theories. The findings suggest people need to feel believed before they will engage with a self-management app. For those who feel abandoned by the healthcare service, a self-management app for chronic low back pain can be a valuable source of ongoing support and reduce feelings of social isolation.

Conclusion

A self-management app, if introduced appropriately and as adjunct to care, can be an empowering tool to self-manage chronic low back pain.

Innovation

Using input from key stakeholders enhances our understanding of the hidden generative mechanisms underpinning a programme's success or failure.

Physical activity interventions for inpatients in secure mental health settings: what works, for whom, in what circumstances and why? A protocol for a realist synthesis

INTRODUCTION

The physical health of individuals with severe mental illness (SMI) is a cause for concern. While the purpose of inpatient mental health settings is rehabilitation and treatment, the physical health of hospitalised patients commonly deteriorates. Physical activity (PA) has been identified as an appropriate intervention to help improve the psychological and physical health of inpatients. We aim to address the gaps in the current literature by exploring how, why, for whom and in what contexts PA interventions help patients with SMI, who receive inpatient treatment, to increase their PA engagement.

METHODS AND ANALYSIS

Realist synthesis: Six steps will be followed: (1) identification of the review question and scope of the review; (2) searching for evidence; (3) screening and appraisal; (4) extraction of data; (5) synthesis of the data and (6) dissemination. Five databases will be searched: Web of Science, PubMed, PsycINFO, PsychArticles and EmBase. A total of 10-15 stakeholders made up of academics and people living with SMI, sport and exercise therapists, psychiatrists, physiotherapists of low, medium and highly secure inpatient settings, will form an expert advisory group. They will provide their insight and knowledge of the secure setting contexts and perceived principles of how PA initiatives being undertaken in their hospitals for patients with SMI work, or not. The results will be published in accordance with the Realist And Meta-narrative Evidence Syntheses-Evolving Standards publication standards.

ETHICS AND DISSEMINATION

Ethical approval has been granted. The review will produce context-specific guidance for Clinical Commissioning Groups and practitioners on how to optimise the provision of PA interventions for people with SMI in inpatient settings.

Implementing a package of essential non-communicable diseases interventions in low- and middle-income countries: a realist review protocol

INTRODUCTION

The burden of non-communicable diseases (NCDs) is increasing rapidly, particularly in low- and middle-income countries (LMIC), accounting for 85% of premature deaths in the region. LMICs have been facing an increasing trend of a double burden of disease (infectious diseases and NCDs) that has led to multiple challenges in prioritising strategies for NCDs control amidst limited resources. Evidence indicates that measures such as the WHO's package of essential non-communicable (PEN) diseases interventions can prevent and control NCDs. However, because of the complexity of such health interventions, there is limited evidence that explains how the intervention works, for whom and in what context. We aim to unpack the causal mechanisms explaining how, why, for whom and in what context PEN prevents and controls NCDs.

METHODS AND ANALYSIS

We propose a realist review to understand how, why, for whom and under what circumstances PEN works or does not work. The review process includes five steps applied iteratively throughout the study: clarification of review scope, searching for evidence, appraising and extracting data, synthesising evidence and drawing conclusions, and disseminating the findings. Programme theories will be developed using the realist logic for theory formulation-Retroductive Theorising. The context-mechanism-outcome (CMO) heuristic tool will be used to develop the programme theories. Portions of the reviewed documents describing constructs of context, mechanism and outcomes will be coded inductively and extracted. These extracted constructs will then be linked abductively to formulate CMO configurations.

ETHICS AND DISSEMINATION

Formal ethical approval is not required for this review. Study findings will be disseminated through publications in peer-reviewed journals, conference presentations and formal and informal reports.

Realist synthesis protocol for understanding which strategies are effective to prevent urinary tract infection in older people in care homes

AIM

To identify and characterize strategies, which contribute to the prevention of urinary tract infection (UTI) in older people living in care homes.

DESIGN

The realist synthesis has four iterative stages to (1) develop initial programme theory; (2) search for evidence; (3) test and refine theory supported by relevant evidence and (4) formulate recommendations. Data from research articles and other sources will be used to explore the connection between interventions and the context in which they are applied in order to understand the mechanisms, which influence the outcomes to prevent UTI.

METHODS

A scoping search of the literature and workshops with stakeholders will identify initial programme theories. These theories will be tested and refined through a systematic search for evidence relating to mechanisms that trigger prevention and recognition of UTI in older people in care homes. Interviews with key stakeholders will establish practical relevance of the theories and their potential for implementation.

DISCUSSION

UTI is the most commonly diagnosed infection in care home residents. Evidence on the effectiveness of strategies to prevent UTI in long-term care facilities does not address the practicality of implementing these approaches in UK care homes. The realist synthesis is designed to examine this important gap in evidence.

IMPACT

Our evidence-informed programme theory will help inform programmes to improve practice to reduce the incidence of UTI in older people living in care homes and related research. Patient and public involvement will be crucial to ensuring that our findings reach carers and the public.

PATIENT AND PUBLIC CONTRIBUTION

Involvement of patient and public representatives is embedded throughout the study to ensure it is underpinned by multiple perspectives of importance to care home residents. Our co-investigator representing patient and public involvement is a lay member of the team and will chair the Project Advisory Group, which has two additional lay members. This will help to ensure that our findings and resources reach carers and the public and represent their voice in our publications and presentations to professional and lay audiences.

Implementation of Home-Based Telerehabilitation of Patients With Stroke in the United States: Protocol for a Realist Review

BACKGROUND

Stroke is a common cause of mortality and morbidity. Insufficient and untimely rehabilitation has been associated with inadequate recovery. Telerehabilitation provides an opportunity for timely and accessible services for individuals with stroke, especially in remote areas. Telerehabilitation is defined as a health care team's use of a communication mode (eg, videoconferencing) to remotely provide rehabilitation services. Telerehabilitation is as effective as facility-based rehabilitation; however, it is infrequently used due to implementation barriers.

OBJECTIVE

The aim of the study is to explore the interaction between the implementation strategies, context, and outcomes of telerehabilitation of patients with stroke.

METHODS

This review will follow four steps: (1) defining the review scope, (2) literature search and quality appraisal, (3) data extraction and evidence synthesis, and (4) narrative development. PubMed via MEDLINE, the PEDro database, and CINAHL will be queried till June 2023 and supplemented with citation tracking and a gray literature search. The relevance and rigor of papers will be appraised using the TAPUPAS (Transparency, Accuracy, Purposivity, Utility, Propriety, Accessibility, and Specificity) and Weight of Evidence frameworks. The reviewers will extract and synthesize data iteratively and develop explanatory links between contexts, mechanisms, and outcomes. The results will be reported according to the Realist Synthesis publication standards set by Wong and colleagues in 2013.

RESULTS

The literature search and screening will be completed in July 2023. Data extraction and analysis will be completed in August 2023, and findings will be synthesized and reported in October 2023.

CONCLUSIONS

This will be the first realist synthesis, uncovering the causal mechanisms to explain how, why, and to what extent implementation strategies impact telerehabilitation adoption and implementation.

Complex Interventions Across Primary and Secondary Care to Optimize Population Kidney Health: A Systematic Review and Realist Synthesis to Understand Contexts, Mechanisms, and Outcomes

BACKGROUND

CKD affects 850 million people worldwide and is associated with high risk of kidney failure and death. Existing, evidence-based treatments are not implemented in at least a third of eligible patients, and there is socioeconomic inequity in access to care. While interventions aiming to improve delivery of evidence-based care exist, these are often complex, with intervention mechanisms acting and interacting in specific contexts to achieve desired outcomes.

METHODS

We undertook realist synthesis to develop a model of these context-mechanism-outcome interactions. We included references from two existing systematic reviews and from database searches. Six reviewers produced a long list of study context-mechanism-outcome configurations based on review of individual studies. During group sessions, these were synthesized to produce an integrated model of intervention mechanisms, how they act and interact to deliver desired outcomes, and in which contexts these mechanisms work.

RESULTS

Searches identified 3371 relevant studies, of which 60 were included, most from North America and Europe. Key intervention components included automated detection of higher-risk cases in primary care with management advice to general practitioners, educational support, and non-patient-facing nephrologist review. Where successful, these components promote clinician learning during the process of managing patients with CKD, promote clinician motivation to take steps toward evidence-based CKD management, and integrate dynamically with existing workflows. These mechanisms have the potential to result in improved population kidney disease outcomes and cardiovascular outcomes in supportive contexts (organizational buy-in, compatibility of interventions, geographical considerations). However, patient perspectives were unavailable and therefore did not contribute to our findings.

CONCLUSIONS

This systematic review and realist synthesis describes how complex interventions work to improve delivery of CKD care, providing a framework within which future interventions can be developed. Included studies provided insight into the functioning of these interventions, but patient perspectives were lacking in available literature.

Health visiting in the UK in light of the COVID-19 pandemic experience (RReHOPE): a realist review protocol

INTRODUCTION

Health visiting services, providing support to under 5s and their families, are organised and delivered in very different ways in different parts of the UK. While there has been attention to the key components of health visiting practice and what works well and how, there is little research on how health visiting services are organised and delivered and how that affects their ability to meet their objectives. The COVID-19 pandemic rapidly disrupted service delivery from March 2020. This realist review aims to synthesise the evidence on changes during the pandemic to identify the potential for improving health visiting services and their delivery.

METHODS AND ANALYSIS

This review will follow the RAMESES (Realist And Meta-narrative Evidence Syntheses: Evolving Standards) quality standards and Pawson's five iterative stages to locate existing theories, search for evidence, select literature, extract data, synthesise evidence and draw conclusions. It will be guided by stakeholder engagement with practitioners, commissioners, policymakers, policy advocates and people with lived experience. This approach will consider the emerging strategies and evolving contexts in which the services are delivered, and the varied outcomes for different groups. A realist logic of analysis will be used to make sense of what was happening to health visiting services during and following the pandemic response through the identification and testing of programme theories. Our refined programme theory will then be used to develop recommendations for improving the organisation, delivery and ongoing postpandemic recovery of health visiting services.

ETHICS AND DISSEMINATION

General University Ethics Panel approval has been obtained from University of Stirling (reference 7662). Dissemination will build on links to policymakers, commissioners, providers, policy advocates and the public. A range of audiences will be targeted using outputs tailored to each. A final stakeholder event focused on knowledge mobilisation will aid development of recommendations.

Grand rounds in methodology: when are realist reviews useful, and what does a 'good' realist review look like?

Research in the quality and safety field often necessitates an approach that supports the development of an in-depth understanding of how a complex phenomenon occurs, or how an intervention works. Realist review is an increasingly popular form of evidence synthesis that provides a theory-driven, interpretive approach to secondary research. Realist reviews offer quality and safety researchers the opportunity to draw on diverse types of evidence to develop explanatory theory about how, when and for whom interventions 'work' or outcomes occur. The approach is flexible, iterative and practical, typically drawing on the experience of policymakers, practitioners and patients throughout the review. With the increasing use of realist reviews, some common misconceptions about the approach have become evident in the literature. This paper introduces what is involved when planning and conducting a realist review, and where the approach can offer most value, as well as outlining common challenges that researchers may face when adopting the approach, and recommended solutions. Our aim is to support researchers who are considering conducting a realist review to understand the key principles and concepts involved, and how they can go about producing high-quality work.

Combining realist evaluation and transformative evaluation to advance research in palliative care: The case of end of life companionship

BACKGROUND

Palliative care requires innovative methods to understand what works, for whom, in what circumstances and why. Realist evaluation has become one prominent approach due to its preoccupation with building, and testing, causal theories to explain the influence of contextual factors on outcomes. Undertaking realist evaluation is not without challenges and may amplify issues of underrepresentation, disempower those working in palliative care, and produce results with poor ecological validity. Complementary approaches are needed which mitigate these challenges, whilst producing credible findings that advances knowledge.

PURPOSE

In this article it is outlined how realist evaluation provides a toolkit to advance research to explain, and empirically test, the complex contours of palliative care. Moreover, it is proposed that transformative evaluation can provide a catalyst to engage and empower those within palliative care, create the opportunity for care transformation, and produce more informed and authentic theories.

DISCUSSION

Contemporary issues in palliative care pertain to the complexity of palliative care, the insufficiency of experimental designs alone, and the challenges of achieving inclusive research participation. In this article it is argued that theory led, participatory, opportunistic and naturalistic approaches can provide an antidote to the issues in the literature. The combination also mitigates many methodological critiques of the individual approaches, by increasing the transformative potential of realist evaluation, and explanatory potential of transformative evaluation.

A realist review of residential treatment for adults with substance use disorder

ISSUES

Completion of residential treatment for substance use disorder (SUD) relates to improvements in substance use and mental health. Findings from systematic reviews have been equivocal about which interventions work best for clients. There has been limited attention to the theories that explain the effectiveness of residential treatment.

APPROACH

We conducted a realist review of the literature to identify program theories that would explain successful and unsuccessful outcomes from residential treatment for SUD. The unit of analysis was context-mechanism-outcome (CMO). Inclusion criteria were studies of residential treatment of more than 30 days for adults with SUD. Pharmacological studies were excluded.

KEY FINDINGS

We identified 24 studies from 5748 screened. The studies were from settings comprising Indigenous programs, faith-based programs, psycho-social interventions and therapeutic communities and were conducted in North America, Scandinavia, Continental Europe and Australasia. We chose six CMO configurations as the best explanations for outcomes from residential treatment. Theories that best explained the mechanisms of change were the need to belong, meaning in life, and self-determination theory.

IMPLICATIONS

Previous research has noted similar outcomes from different residential treatment interventions, but has not been able to explain these similarities. In contrast, our findings suggest that the outcomes can be explained by causal mechanisms that apply across all programs, regardless of the philosophy of treatment.

CONCLUSION

We identified six CMO configurations whose mechanisms of change could be explained by three overarching theories-the need to belong, meaning in life and self-determination theory. The findings apply across ethnicities and genders.

Understanding how and under what circumstances decision coaching works for people making healthcare decisions: a realist review

Background

Decision coaching is non-directive support delivered by a trained healthcare provider to help people prepare to actively participate in making healthcare decisions. This study aimed to understand how and under what circumstances decision coaching works for people making healthcare decisions.

Methods

We followed the realist review methodology for this study. This study was built on a Cochrane systematic review of the effectiveness of decision coaching interventions for people facing healthcare decisions. It involved six iterative steps: (1) develop the initial program theory; (2) search for evidence; (3) select, appraise, and prioritize studies; (4) extract and organize data; (5) synthesize evidence; and (6) consult stakeholders and draw conclusions.

Results

We developed an initial program theory based on decision coaching theories and stakeholder feedback. Of the 2594 citations screened, we prioritized 27 papers for synthesis based on their relevance rating. To refine the program theory, we identified 12 context-mechanism-outcome (CMO) configurations. Essential mechanisms for decision coaching to be initiated include decision coaches’, patients’, and clinicians’ commitments to patients’ involvement in decision making and decision coaches’ knowledge and skills (four CMOs). CMOs during decision coaching are related to the patient (i.e., willing to confide, perceiving their decisional needs are recognized, acquiring knowledge, feeling supported), and the patient-decision coach interaction (i.e., exchanging information, sharing a common understanding of patient’s values) (five CMOs). After decision coaching, the patient’s progress in making or implementing a values-based preferred decision can be facilitated by the decision coach’s advocacy for the patient, and the patient’s deliberation upon options (two CMOs). Leadership support enables decision coaches to have access to essential resources to fulfill their role (one CMOs).

Discussion

In the refined program theory, decision coaching works when there is strong leadership support and commitment from decision coaches, clinicians, and patients. Decision coaches need to be capable in coaching, encourage patients’ participation, build a trusting relationship with patients, and act as a liaison between patients and clinicians to facilitate patients’ progress in making or implementing an informed values-based preferred option. More empirical studies, especially qualitative and process evaluation studies, are needed to further refine the program theory.

Realist inquiry into Maternity care @ a Distance (ARM@DA): realist review protocol

INTRODUCTION

One of the most commonly reported COVID-19-related changes to all maternity services has been an increase in the use of digital clinical consultations such as telephone or video calling; however, the ways in which they can be optimally used along maternity care pathways remain unclear. It is imperative that digital service innovations do not further exacerbate (and, ideally, should tackle) existing inequalities in service access and clinical outcomes. Using a realist approach, this project aims to synthesise the evidence around implementation of digital clinical consultations, seeking to illuminate how they can work to support safe, personalised and appropriate maternity care and to clarify when they might be most appropriately used, for whom, when, and in what contexts?

METHODS AND ANALYSIS

The review will be conducted in four iterative phases, with embedded stakeholder involvement: (1) refining the review focus and generating initial programme theories, (2) exploring and developing the programme theories in light of evidence, (3) testing/refining the programme theories and (4) constructing actionable recommendations. The review will draw on four sources of evidence: (1) published literature (searching nine bibliographic databases), (2) unpublished (grey) literature, including research, audit, evaluation and policy documents (derived from Google Scholar, website searches and e-thesis databases), (3) expertise contributed by service user and health professional stakeholder groups (n=20-35) and (4) key informant interviews (n=12). Included papers will consist of any study design, in English and from 2010 onwards. The review will follow the Realist and Meta-narrative Evidence Synthesis Evolving Standards quality procedures and reporting guidance.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the University of Nottingham, Faculty of Medicine and Health Sciences Ethics Committee (FMHS 426-1221). Informed consent will be obtained for all key informant interviews. Findings will be disseminated in a range of formats relevant to different audiences.

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.

A realist review protocol on communications for community engagement in maternal and newborn health programmes in low- and middle-income countries

BACKGROUND

Community engagement (CE) has been increasingly implemented across health interventions, including for maternal and newborn health (MNH). This may take various forms, from participatory women's groups and community health committees to public advocacy days. While research suggests a positive influence of CE on MNH outcomes, such as mortality or care-seeking behaviour, there is a need for further evidence on the processes of CE in different settings in order to inform the future development and implementation of CE across programmes. Communication is an integral component of CE serving as a link between the programme and community. The aim of the realist review described in this protocol is to understand how, why, to what extent, and for whom CE contributes to intended and unintended outcomes in MNH programming, focusing on the communication components of CE.

METHODS

Realist review methodology will be used to provide a causal understanding of what communication for CE interventions in MNH programming work, for whom, to what extent, why, and how. This will be done by developing and refining programme theories on communications for CE in MNH through a systematic review of the literature and engaging key experts for input and feedback. By extrapolating context-mechanism-outcome configurations, this review seeks to understand how certain contexts trigger or inhibit specific mechanisms and what outcomes this interaction generates when communication in CE interventions is used in MNH programming.

DISCUSSION

A realist philosophy is well-suited to address the aims of this study because of the complex nature of CE. The review findings will be used to inform a realist evaluation case study of CE for an MNH programme in order to ascertain transferable findings that can inform and guide engagement activities in various settings. Findings will also be shared with stakeholders and experts involved in the consultative processes of the review (through workshops or policy briefs) in order to ensure the relevance of these findings to policy and practice.

Unpacking the design, implementation and uptake of community-integrated health care services: a critical realist synthesis

Introduction

Community-integrated care initiatives are increasingly being used for social and health service delivery and show promising outcomes. Nevertheless, it is unclear what structures and underlining causal agents (generative mechanisms) are responsible for explaining how and why they work or not.

Methods and analysis

Critical realist synthesis, a theory-driven approach to reviewing and synthesising literature based on the critical realist philosophy of science, underpinned the study. Two lenses guided our evidence synthesis, the community health system and the patient-focused perspective of integrated care. The realist synthesis was conducted through the following steps: (1) concept mining and framework formulation, (2) searching for and scrutinising the evidence, (3) extracting and synthesising the evidence (4) developing the narratives from causal explanatory theories, and (5) disseminate, implement and evaluate.

Results

Three programme theories, each aligning with three groups of stakeholders, were unearthed. At the systems level, three bundles of mechanisms were identified, that is, (1) commitment and motivation, (2) willingness to address integrated health concerns and (3) shared vision and goals. At the provider level, five bundles of mechanisms critical to the successful implementation of integrated care initiatives were abstracted, that is, (1) shared vision and buy-in, (2) shared learning and empowerment, (3) perceived usefulness, (4) trust and perceived support and (5) perceived role recognition and appreciation. At the user level, five bundles of mechanisms were identified, that is, (1) motivation, (2) perceived interpersonal trust, (3) user-empowerment, (4) perceived accessibility to required services and (5) self-efficacy and self-determination.

Conclusion

We systematically captured mechanism-based explanatory models to inform practice communities on how and why community-integrated models work and under what health systems conditions.

Why do acute healthcare staff engage in unprofessional behaviours towards each other and how can these behaviours be reduced? A realist review protocol

INTRODUCTION

Unprofessional behaviours encompass many behaviours including bullying, harassment and microaggressions. These behaviours between healthcare staff are problematic; they affect people's ability to work, to feel psychologically safe at work and speak up and to deliver safe care to patients. Almost a fifth of UK National Health Service staff experience unprofessional behaviours in the workplace, with higher incidence in acute care settings and for staff from minority backgrounds. Existing analyses have investigated the effectiveness of strategies to reduce these behaviours. We seek to go beyond these, to understand the range and causes of such behaviours, their negative effects and how mitigation strategies may work, in which contexts and for whom.

METHODS AND ANALYSIS

This study uses a realist review methodology with stakeholder input comprising a number of iterative steps: (1) formulating initial programme theories drawing on informal literature searches and literature already known to the study team, (2) performing systematic and purposive searches for grey and peer-reviewed literature on Embase, CINAHL and MEDLINE databases as well as Google and Google Scholar, (3) selecting appropriate documents while considering rigour and relevance, (4) extracting data, (5) and synthesising and (6) refining the programme theories by testing the theories against the newly identified literature.

ETHICS AND DISSEMINATION

Ethical review is not required as this study is a secondary research. An impact strategy has been developed which includes working closely with key stakeholders throughout the project. Step 7 of our project will develop pragmatic resources for managers and professionals, tailoring contextually-sensitive strategies to reduce unprofessional behaviours, identifying what works for which groups. We will be guided by the 'Evidence Integration Triangle' to implement the best strategies to reduce unprofessional behaviours in given contexts. Dissemination will occur through presentation at conferences, innovative methods (cartoons, videos, animations and/or interactive performances) and peer-reviewed journals.

OUP accepted manuscript

Appropriate models of survivorship care for the growing number of adult survivors of childhood cancer are unclear. We conducted a realist review to describe how models of care that include primary care and relevant resources (eg, tools, training) could be effective for adult survivors of childhood cancer. We first developed an initial program theory based on qualitative literature (studies, commentaries, opinion pieces) and stakeholder consultations. We then reviewed quantitative evidence and consulted stakeholders to refine the program theory and develop and refine context-mechanism-outcome hypotheses regarding how models of care that include primary care could be effective for adult survivors of childhood cancer. Effectiveness for both resources and models is defined by survivors living longer and feeling better through high-value care. Intermediate measures of effectiveness evaluate the extent to which survivors and providers understand the survivor’s history, risks, symptoms and problems, health-care needs, and available resources. Thus, the models of care and resources are intended to provide information to survivors and/or primary care providers to enable them to obtain/deliver appropriate care. The variables from our program theory found most consistently in the literature include oncology vs primary care specialty, survivor and provider knowledge, provider comfort treating childhood cancer survivors, communication and coordination between and among providers and survivors, and delivery/receipt of prevention and surveillance of late effects. In turn, these variables were prominent in our context-mechanism-outcome hypotheses. The findings from this realist review can inform future research to improve childhood cancer survivorship care and outcomes.

Literature searching methods or guidance and their application to public health topics: A narrative review

Background

Information specialists conducting searches for systematic reviews need to consider key questions around which and how many sources to search. This is particularly important for public health topics where evidence may be found in diverse sources.

Objectives

The objective of this review is to give an overview of recent studies on information retrieval guidance and methods that could be applied to public health evidence and used to guide future searches.

Methods

A literature search was performed in core databases and supplemented by browsing health information journals and citation searching. Results were sifted and reviewed.

Results

Seventy‐two papers were found and grouped into themes covering sources and search techniques. Public health topics were poorly covered in this literature.

Discussion

Many researchers follow the recommendations to search multiple databases. The review topic influences decisions about sources. Additional sources covering grey literature eliminate bias but are time‐consuming and difficult to search systematically. Public health searching is complex, often requiring searches in multidisciplinary sources and using additional methods.

Conclusions

Search planning is advisable to enable decisions about which and how many sources to search. This could improve with more work on modelling search scenarios, particularly in public health topics, to examine where publications were found and guide future research.

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

The approach to identifying evidence for inclusion in realist reviews differs from that used in 'traditional' systematic reviews. Guidance suggests that realist reviews should be inclusive of diverse data from a range of sources, gathered in iterative searching cycles. Saturation is prioritised over exhaustiveness. Supplementary techniques such as citation snowballing are emphasised as potentially important sources of evidence. This paper describes the processes used to identify evidence in a selection of realist reviews focused on primary health care settings and examines the origin and type of evidence selected for inclusion. Data from five realist reviews were extracted from (a) reviewers' reference management libraries and (b) records kept by review teams. Although all reviews focused on primary health care, they used data from a wide range of document types and research designs, drawing on learning from multiple perspectives and settings, and sourced the documents containing this data in a variety of ways. Systematic searching of academic databases played an important role, supplementary search techniques such as snowballing were used to identify a significant proportion of documents included in the reviews. Our analysis demonstrates the diverse data sources used within realist reviews and the need for flexible, responsive efforts to identify relevant documents. Reviewers and information specialists should devise approaches to data gathering that reflect the individual needs of realist review projects and report these transparently.

The role of trust and hope in antipsychotic medication reviews between GPs and service users a realist review

BACKGROUND

Increasing number of service users diagnosed with schizophrenia and psychosis are being discharged from specialist secondary care services to primary care, many of whom are prescribed long-term antipsychotics. It is unclear if General Practitioners (GPs) have the confidence and experience to appropriately review and adjust doses of antipsychotic medication without secondary care support.

AIM

To explore barriers and facilitators of conducting antipsychotic medication reviews in primary care for individuals with no specialist mental health input.

DESIGN & SETTING

Realist review in general practice settings.

METHOD

A realist review has been conducted to synthesise evidence on antipsychotic medication reviews conducted in primary care with service users diagnosed with schizophrenia or psychosis. Following initial scoping searches and discussions with stakeholders, a systematic search and iterative secondary searches were conducted. Articles were systematically screened and analysed to develop a realist programme theory explaining the contexts (C) and mechanisms (M) which facilitate or prevent antipsychotic medication reviews (O) in primary care settings, and the potential outcomes of medication reviews.

RESULTS

Meaningful Antipsychotic medication reviews may not occur for individuals with only primary care medical input. Several, often mutually reinforcing, mechanisms have been identified as potential barriers to conducting such reviews, including low expectations of recovery for people with severe mental illness, a perceived lack of capability to understand and participate in medication reviews, linked with a lack of information shared in appointments between GPs and Service Users, perceived risk and uncertainty regarding antipsychotic medication and illness trajectory.

CONCLUSIONS

The review identified reciprocal and reinforcing stereotypes affecting both GPs and service users. Possible mechanisms to counteract these barriers are discussed, including realistic expectations of medication, and the need for increased information sharing and trust between GPs and service users.

Engaging communities in non-communicable disease research and interventions in low- and middle-income countries: a realist review protocol

INTRODUCTION

Engaging communities and intended beneficiaries at various stages of health research is a recommended practice. The contribution of community engagement to non-communicable disease research in low- and middle-income countries has not yet been extensively studied or synthesised. This protocol describes the steps towards generating an understanding of community engagement in the context of non-communicable disease research, prevention and health promotion using a realist review approach. A realist lens enables a rich explanatory approach to causation while capturing complexity, and an openness to multiple outcomes, including unintended consequences. The review will thus develop an understanding of community engagement without assuming that such practices result in more ethical research or effective interventions.

METHODS AND ANALYSIS

We propose a realist approach aiming to examine how, why, under what circumstances and for whom community engagement works or does not work. The iterative review steps include clarifying the review scope; searching for evidence; appraising studies and extracting data; synthesising evidence and drawing conclusions; and disseminating, implementing and evaluating the findings. Principles of meta-narrative review (pragmatism, pluralism, historicity, contestation, reflexivity and peer review) are employed to ensure practicable and contextualised review outputs. The proposed review will draw on theoretical and empirical literature beyond specific diseases or settings, but with a focus on informing non-communicable disease research and interventions in low- and middle-income countries. The synthesis of existing literature will be complemented by qualitative realist interviews and stakeholder consultation. Through drawing on multiple types of evidence and input from both experts and intended beneficiaries, the review will provide critical and pragmatic insights for research and community engagement in low- and middle-income countries.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the University of the Witwatersrand. Dissemination will include traditional academic channels, institutional communications, social media and discussions with a wide range of stakeholders.

Protocol for a realist synthesis of health systems responsiveness in low-income and middle-income countries

INTRODUCTION

Health systems responsiveness is a key objective of any health system, yet it is the least studied of all objectives particularly in low-income and middle-income countries. Research on health systems responsiveness highlights its multiple elements, for example, dignity and confidentiality. Little is known, however, about underlying theories of health systems responsiveness, and the mechanisms through which responsiveness works. This realist synthesis contributes to bridging these two knowledge gaps.

METHODS AND ANALYSIS

In this realist synthesis, we will use a four-step process, comprising: mapping of theoretical bases, formulation of programme theories, theory refinement and testing of programme theories using literature and empirical data from Ghana and Vietnam. We will include theoretical and conceptual pieces, reviews, empirical studies and grey literature, alongside the primary data. We will explore responsiveness as entailing external and internal interactions within health systems. The search strategy will be purposive and iterative, with continuous screening and refinement of theories. Data extraction will be combined with quality appraisal, using appropriate tools. Each fragment of evidence will be appraised as it is being extracted, for its relevance to the emerging programme theories and methodological rigour. The extracted data pertaining to contexts, mechanisms and outcomes will be synthesised to identify patterns and contradictions. Results will be reported using narrative explanations, following established guidance on realist syntheses.

ETHICS AND DISSEMINATION

Ethics approvals for the wider RESPONSE (Improving health systems responsiveness to neglected health needs of vulnerable groups in Ghana and Vietnam) study, of which this review is one part, were obtained from the ethics committees of the following institutions: London School of Hygiene and Tropical Medicine (ref: 22981), University of Leeds, School of Medicine (ref: MREC19-051), Ghana Health Service (ref: GHS-ERC 012/03/20) and Hanoi University of Public Health (ref: 020-149/DD-YTCC).We will disseminate results through academic papers, conference presentations and stakeholder workshops in Ghana and Vietnam.

Community mobilisation approaches to preventing and reducing adolescent multiple risk behaviour: a realist review protocol

BACKGROUND

Adolescent multiple risk behaviour (MRB) continues to be a global health issue. Most interventions have focused on the proximal causes of adolescent MRB such as peer or family influence, rather than targeting the wider environmental or structural context. There is increasing recognition that community mobilisation approaches could be beneficial for adolescent health. Despite this, there are gaps in the current literature, theory and implementation that would benefit from a realist approach due to the suitability of this methodology to analysing complex interventions. The objective of this study is to understand 'how, why, for whom and in what circumstances and time periods' do community mobilisation interventions work to prevent and/or reduce adolescent multiple risk behaviour.

METHODS

This is a protocol for a realist review. The review will use a six-stage iterative process, guided by the RAMESES framework. We will systematically search PubMed, MEDLINE, PsycINFO, Web of Science, CINAHL and Sociological Abstracts, from their inception to 2021. Studies will be screened for relevance to the programme theory and included based on a priori eligibility criteria including (1) reporting a community mobilisation intervention (2) targeting two health risk behaviors (3) for adolescent populations. Two independent reviewers will select, screen and extract data related to the program theory from all relevant sources. A realist logic of analysis will be used to identify all context-mechanism-outcome configurations that contribute to our programme theory. The findings will be synthesised to produce a refined programme theory model.

DISCUSSION

The goal of this realist review is to identify and refine a programme theory for community mobilisation approaches to the prevention and/or reduction of adolescent multiple risk behaviour. Our aim is that the findings surrounding the programme theory refinement can be used to develop and implement adolescent multiple risk behaviour interventions and maintain collaboration between local policy makers, researchers and community members.

[Development of intervention databases to promote evidence-based prevention and health promotion-methodological considerations]

Municipal actors do not experience sufficient scientific support in the development and selection of preventive and health promoting interventions. Intervention databases can remedy this by presenting scientifically validated and well-documented interventions. This allows local decisions to be informed by scientific evidence on the effectiveness of interventions. The databases can also be used to promote quality development of interventions.This paper explains methodological and conceptual considerations on how preventive and health-promoting interventions can be identified for databases and how they can be classified in terms of their effectiveness and prepared in a way that is appropriate for the target group. It is based on findings from the public health literature and the project "Ageing in Balance" ("Älter werden in Balance") of the Bundeszentrale für gesundheitliche Aufklärung (BZgA).Systematic reviews are of limited use in the search for suitable interventions for the database, partly because the types of interventions listed in them are limited and information relevant to implementation is often incompletely presented. However, it seems promising to include interventions from practice in the database if they are additionally classified with regard to their effectiveness or if consequences for further development and evaluation are formulated. In addition, as much information as possible should be provided on the practical implementation of interventions. A first suggestion shows what a description of the measures could look like. In addition, manuals for the implementation of measures should be available.

Understanding the implementation (including women's use) of maternity waiting homes in low-income and middle-income countries: a realist synthesis protocol

INTRODUCTION

Maternity waiting homes in low-income and middle-income countries provide accommodation near health facilities for pregnant women close to the time of birth to promote facility-based birth and birth with a skilled professional and to enable timely access to emergency obstetric services when needed. To date, no studies have provided a systematic, comprehensive synthesis explaining facilitators and barriers to successful maternity waiting home implementation and whether and how implementation strategies and recommendations vary by context. This synthesis will systematically consolidate the evidence, answering the question, 'How, why, for whom, and in what context are maternity waiting homes successfully implemented in low-income and middle-income countries?'.

METHODS AND ANALYSIS

Methods include standard steps for realist synthesis: determining the scope of the review, searching for evidence, appraising and extracting data, synthesising and analysing the data and developing recommendations for dissemination. Steps are iterative, repeating until theoretical saturation is achieved. Searching will be conducted in 13 electronic databases with results managed in Eppi-Reviewer V.4. There will be no language, study-type or document-type restrictions. Items documented prior to 1990 will be excluded. To ensure our initial and revised programme theories accurately reflect the experiences and knowledge of key stakeholders, most notably the beneficiaries, interviews will be conducted with maternity waiting home users/nonusers, healthcare staff, policymakers and programme designers. All data will be analysed using context-mechanism-outcome configurations, refined and synthesised to produce a final programme theory.

ETHICS AND DISSEMINATION

Ethics approval for the project will be obtained from the Mozambican National Bioethical Commission, Jimma University College of Health Sciences Institutional Review Board and the University of Saskatchewan Bioethical Research Ethics Board. To ensure results of the evaluation are available for uptake by a wide range of stakeholders, dissemination will include peer-reviewed journal publication, a plain-language brief, and conference presentations to stakeholders' practice audiences.

The effects of interoperable information technology networks on patient safety: a realist synthesis

Background

Interoperable networks connect information technology systems of different organisations, allowing professionals in one organisation to access patient data held in another one. Health policy-makers in many countries believe that they will improve the co-ordination of services and, hence, the quality of services and patient safety. To the best of our knowledge, there have not been any previous systematic reviews of the effects of these networks on patient safety.

Objectives

The aim of the study was to establish how, why and in what circumstances interoperable information technology networks improved patient safety, failed to do so or increased safety risks. The objectives of the study were to (1) identify programme theories and prioritise theories to review; (2) search systematically for evidence to test the theories; (3) undertake quality appraisal, and use included texts to support, refine or reject programme theories; (4) synthesise the findings; and (5) disseminate the findings to a range of audiences.

Design

Realist synthesis, including consultation with stakeholders in nominal groups and semistructured interviews.

Settings and participants

Following a stakeholder prioritisation process, several domains were reviewed: older people living at home requiring co-ordinated care, at-risk children living at home and medicines reconciliation services for any patients living at home. The effects of networks on services in health economies were also investigated.

Intervention

An interoperable network that linked at least two organisations, including a maximum of one hospital, in a city or region.

Outcomes

Increase, reduction or no change in patients’ risks, such as a change in the risk of taking an inappropriate medication.

Results

We did not find any detailed accounts of the ways in which interoperable networks are intended to work and improve patient safety. Theory fragments were identified and used to develop programme and mid-range theories. There is good evidence that there are problems with the co-ordination of services in each of the domains studied. The implicit hypothesis about interoperable networks is that they help to solve co-ordination problems, but evidence across the domains showed that professionals found interoperable networks difficult to use. There is insufficient evidence about the effectiveness of interoperable networks to allow us to establish how and why they affect patient safety.

Limitations

The lack of evidence about patient-specific measures of effectiveness meant that we were not able to determine ‘what works’, nor any variations in what works, when interoperable networks are deployed and used by health and social care professionals.

Conclusions

There is a dearth of evidence about the effects of interoperable networks on patient safety. It is not clear if the networks are associated with safer treatment and care, have no effects or increase clinical risks.

Future work

Possible future research includes primary studies of the effectiveness of interoperable networks, of economies of scope and scale and, more generally, on the value of information infrastructures.

Implementation of geriatric assessment in oncology settings: A systematic realist review

Older adults with cancer are more likely to have worse clinical outcomes than their younger counterparts, and shared decision-making can be difficult, due to both complexity from adverse ageing and under-representation in clinical trials. Geriatric assessment (GA) has been increasingly recognised as a predictive and prehabilitative tool for older adults with cancer. However, GA has been notoriously difficult to implement in oncological settings due to workforce, economic, logistical, and practical barriers. We aimed to review the heterogenous literature on implementation of GA in oncology settings to understand the different implementation context configurations of GA and the mechanisms they trigger to enable successful implementation. A systematic realist review was undertaken in two stages: i) systematic searches with structured data extraction combined with iterative key stakeholder consultations to develop programme theories for implementing GA in oncology settings; ii) synthesis to refine programme theories. Medline, Embase, PsycInfo, Cochrane Library, CINAHL, Web of Science, Scopus, ASSIA, Epistemonikos, JBI Database of Systematic Reviews and Implementation Reports, DARE and Health Technology Assessment were searched. Four programme theories were developed from 53 included articles and 20 key stakeholder consultations addressing the major barriers of GA implementation in oncology practice: time (leveraging non-specialists), funding (creating favourable health economics), practicalities (establishing the use of GA in cancer care), and managing limited resources. We demonstrate that a whole system approach is required to improve the implementation of GA in cancer settings. This review will help inform policy decisions regarding implementation of GA and provide a basis for further implementation research.
