Governmental student funding systems for higher education: an international perspective

The worldwide surge in demand for higher education (HE) aligns with an increasing need for effective student funding systems, particularly in countries where poverty poses a significant barrier to accessing HE. An international perspective on governmental student funding systems allows us to examine how other governments have implemented these systems to benefit their citizens. The aim of this article is thus to provide a global view of the functioning and challenges pertaining to student funding systems and to shed light on the policies in place in the international landscape. The realist systematic literature review methodology was deemed the most suitable for this study as various scholars have previously studied different facets of the topic. This study aligns with the interpretive research paradigm and qualitative methods. The desired information therefore already exists within the body of knowledge, although it has not yet been analyzed through this particular method. It is evident that both developing and developed countries experience challenges regarding student funding, both in the purpose thereof as well as in the implementation. This is a universal issue, and an in-depth literature review confirmed this phenomenon.

Engagement in Distance Healthcare Simulation Debriefing: A Concept Development and Framework.

Understanding distance health care simulation debriefing is crucial in light of the increased use of and emerging technology in remote education for reasons of accessibility, global collaboration, and continuous professional development. This article is a confluence of a number of previously published studies designed to serve as a foundation to develop the concept of "engagement in health care distance simulation debriefing" using the Schwartz-Barcott & Kim hybrid mixed methods model. The model uses 3 phases: theoretical (a realist systematic review of the literature), fieldwork (3 exploratory studies and 2 pilot experimental studies), and analytical (analysis of the theoretical and fieldwork findings through expert discussion). This study defines the concept of "engagement in health care simulation distance debriefing" through exploration of its uses and analysis in literature, interviews, and expert review. The hybrid approach to the analysis provided rigor to generate a new, reflective conceptual model. This conceptual model defines the complexity in engagement during distance debriefing and helps shape the development of simulationists and debriefers, leading to more effective distance simulations and debriefings.

Examining how goals of care communication are conducted between doctors and patients with severe acute illness in hospital settings: A realist systematic review.

Patient involvement in goals of care decision-making has shown to enhance satisfaction, affective-cognitive outcomes, allocative efficiency, and reduce unwarranted clinical variation. However, the involvement of patients in goals of care planning within hospitals remains limited, particularly where mismatches in shared understanding between doctors and patients are present. To identify and critically examine factors influencing goals of care conversations between doctors and patients during acute hospital illness. Realist systematic review following the RAMESES standards. A protocol has been published in PROSPERO (CRD42021297410). The review utilised realist synthesis methodology, including a scoping literature search to generate initial theories, theory refinement through stakeholder consultation, and a systematic literature search to support program theory. Data were collected from Medline, PubMed, Embase, CINAHL, PsychINFO, Scopus databases (1946 to 14 July 2023), citation tracking, and Google Scholar. Open-Grey was utilized to identify relevant grey literature. Studies were selected based on relevance and rigor to support theory development. Our analysis included 52 papers, supporting seven context-mechanism-output (CMO) hypotheses. Findings suggest that shared doctor-patient understanding relies on doctors being confident, competent, and personable to foster trusting relationships with patients. Low doctor confidence often leads to avoidance of discussions. Moreover, information provided to patients is often inconsistent, biased, procedure-focused, and lacks personalisation. Acute illness, medical jargon, poor health literacy, and high emotional states further hinder patient understanding. Goals of care conversations in hospitals are nuanced and often suboptimal. To improve patient experiences and outcome of care interventions should be personalised and tailored to individual needs, emphasizing effective communication and trusting relationships among patients, families, doctors, and healthcare teams. Inclusion of caregivers and acknowledgment at the service level are crucial for achieving desired outcomes. Implications for policy, research, and clinical practice, including further training and skills development for doctors, are discussed.

Mental Health Causation in the Construction Industry: A Systematic Review Employing a Psychological Safety Climate Model

The construction industry has a lamentable reputation for having a high prevalence of suicides and mental health (MH) problems. Several government and academic reports have identified that construction workers are at a far higher risk of MH disorders than workers in other industrial sectors. While studies on construction workers’ MH have significantly increased in recent years, a systematic review of the potential causes of MH problems in the industry has hitherto eluded construction researchers. This study fills this ominous knowledge gap by conducting a realist systematic review of the literature published since 2003. The review conducted adopts the psychological safety climate model of PSC-12 to create a comprehensive list of MH causation (sourced from a rich literature synthesis) as a precursor to developing a theoretical model that identifies MH causations affecting distinct psychological safety climates within the industry. Emergent findings identify 43 MH causation factors with high job demand as the most significant contributor, followed by interpersonal relationships, low job control, low job support and physical status. In addition, it is found that organisation participation factors have been the major areas of focus, while management commitment and management priority are under-researched areas. Moreover, research gaps within the four dimensions of the PCS-12 model were explored to distinguish new potential research areas to address the knowledge gaps observed. In practical terms, the study collates and presents a comprehensive theoretical model of MH causations, providing a concise source of practical knowledge for practitioners.

Re-orientating systematic reviews to rigorously examine what works, for whom and how: Example of a realist systematic review of school-based prevention of dating and gender violence.

Conventional systematic reviews offer few insights into for whom and how interventions work. 'Realist reviews' examine such questions via examining 'context-mechanism-outcome configurations' (CMOCs) but are insufficiently rigorous in how evidence is identified, assessed and synthesised. We developed 'realist systematic reviews', addressing similar questions to realist reviews but using rigorous methods. We applied this to synthesising evidence on school-based prevention of dating and relationship violence (DRV) and gender-based violence (GBV). This paper reflects on overall methods and findings, drawing on papers reporting each analysis. Drawing on intervention descriptions, theories of change and process evaluations, we developed initial CMOC hypotheses: interventions triggering 'school-transformation' mechanisms (preventing violence by changing school environments) will achieve larger effects than those triggering 'basic-safety' (stopping violence by emphasising its unacceptability) or 'positive-development' (developing students' broader skills and relationships) mechanisms; however, school transformation would only work in schools with high organisational capacity. We used various innovative analyses, some of which aimed to test these hypotheses and some of which were inductive, drawing on available findings to augment and refine the CMOCs. Overall, interventions were effective in reducing long-term DRV but not GBV or short-term DRV. DRV prevention occurred most effectively via the 'basic-safety' mechanism. 'School-transformation' mechanisms were more effective in preventing GBV but only in high-income countries. Impacts on long-term DRV victimisation were greater when working with a critical mass of participating girls. Impacts on long-term DRV perpetration were greater for boys. Interventions were more effective when focusing on skills, attitudes and relationships, or lacking parental involvement or victim stories. Our method provided novel insights and should be useful to policy-makers seeking the best interventions for their contexts and the most information to inform implementation.

Models of integrated care for young people experiencing medical emergencies related to mental illness: a realist systematic review

Mental illness heightens risk of medical emergencies, emergency hospitalisation, and readmissions. Innovations for integrated medical–psychiatric care within paediatric emergency settings may help adolescents with acute mental disorders to get well quicker and stay well enough to remain out of hospital. We assessed models of integrated acute care for adolescents experiencing medical emergencies related to mental illness (MHR). We conducted a systematic review by searching MEDLINE, PsychINFO, Embase, and Web of Science for quantitative studies within paediatric emergency medicine, internationally. We included populations aged 8–25 years. Our outcomes were length of hospital stay (LOS), emergency hospital admissions, and rehospitalisation. Limits were imposed on dates: 1990 to June 2021. We present a narrative synthesis. This study is registered on PROSPERO: 254,359. 1667 studies were screened, 22 met eligibility, comprising 39,346 patients. Emergency triage innovations reduced admissions between 4 and 16%, including multidisciplinary staffing and training for psychiatric assessment (F(3,42) = 4.6, P < 0.05, N = 682), and telepsychiatry consultations (aOR = 0.41, 95% CI 0.28–0.58; P < 0.001, N = 597). Psychological therapies delivered in emergency departments reduced admissions 8–40%, including psychoeducation (aOR = 0.35, 95% CI 0.17–0.71, P < 0.01, N = 212), risk-reduction counselling for suicide prevention (OR = 2.78, 95% CI 0.55–14.10, N = 348), and telephone follow-up (OR = 0.45, 95% CI 0.33–0.60, P < 0.001, N = 980). Innovations on acute wards reduced readmissions, including guided meal supervision for eating disorders (P = 0.27), therapeutic skills for anxiety disorders, and a dedicated psychiatric crisis unit (22.2 vs 8.5% (P = 0.008). Integrated pathway innovations reduced readmissions between 8 and 37% including family-based therapy (FBT) for eating disorders (X2(1,326) = 8.40, P = 0.004, N = 326), and risk-targeted telephone follow-up or outpatients for all mental disorders (29.5 vs. 5%, P = 0.03, N = 1316). Studies occurred in the USA, Canada, or Australia. Integrated care pathways to psychiatric consultations, psychological therapies, and multidisciplinary follow-up within emergency paediatric services prevented lengthy and repeat hospitalisation for MHR emergencies. Only six of 22 studies adjusted for illness severity and clinical history between before- and after-intervention cohorts and only one reported socio-demographic intervention effects.

A Realist Systematic Review to Understand the Effectiveness of Health-Related Interventions Designed to Decrease Overweight, Obesity and Unemployment in Adults

ObjectivesObesity, overweight and unemployment are intertwined, with common underlying causes however limited studies have examined this association. Holistic approaches are therefore required to understand this inter-relationship. The aim of this realist synthesis was to identify the common strategies used by health-related interventions to reduce weight and unemployment and to understand the contexts and mechanisms that determine effectiveness.MethodsElectronic literature searches were conducted in Cochrane library, Medline, SocIndex, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and PsychInfo. Data from included articles were extracted and coded for Context-Outcome-Mechanism configurations (CMOcs). A realist approach to thematic analysis was used to synthesis and refine the final program theory building on the initial program theory. Results are presented using a narrative synthesis.ResultsA total of 83 studies meeting the inclusion criteria and assessment for rigor and relevance were included. 17 CMOcs were identified that demonstrated interactions between intervention strategy, context of intervention, responses generated by the intervention (mechanism) and outcomes. Findings indicate implementation of multicomponent interventions tailored to the needs of the target group are more likely to result in positive outcomes. Additionally, consideration of both individual and external contextual factors would enhance the design, delivery and effectiveness of health-related interventions designed to reduce obesity and improve re-employment.ConclusionsThis is the first realist review of health-related interventions implemented to reduce overweight, obesity and unemployment. The findings contribute to a deeper understanding of the determinants of effectiveness and how to holistically address unemployment and obesity using common strategies.Funding SourcesThis work is funded by grants from the EU Interreg European Regional Development Fund.

A realist systematic review of evidence from low- and middle-income countries of interventions to improve immunization data use

BackgroundThe use of routine immunization data by health care professionals in low- and middle-income countries remains an underutilized resource in decision-making. Despite the significant resources invested in developing national health information systems, systematic reviews of the effectiveness of data use interventions are lacking. Applying a realist review methodology, this study synthesized evidence of effective interventions for improving data use in decision-making.MethodsWe searched PubMed, POPLINE, Centre for Agriculture and Biosciences International Global Health, and African Journals Online for published literature. Grey literature was obtained from conference, implementer, and technical agency websites and requested from implementing organizations. Articles were included if they reported on an intervention designed to improve routine data use or reported outcomes related to data use, and targeted health care professionals as the principal data users. We developed a theory of change a priori for how we expect data use interventions to influence data use. Evidence was then synthesized according to data use intervention type and level of the health system targeted by the intervention.ResultsThe searches yielded 549 articles, of which 102 met our inclusion criteria, including 49 from peer-reviewed journals and 53 from grey literature. A total of 66 articles reported on immunization data use interventions and 36 articles reported on data use interventions for other health sectors. We categorized 68 articles as research evidence and 34 articles as promising strategies. We identified ten primary intervention categories, including electronic immunization registries, which were the most reported intervention type (n = 14). Among the research evidence from the immunization sector, 32 articles reported intermediate outcomes related to data quality and availability, data analysis, synthesis, interpretation, and review. Seventeen articles reported data-informed decision-making as an intervention outcome, which could be explained by the lack of consensus around how to define and measure data use.ConclusionsFew immunization data use interventions have been rigorously studied or evaluated. The review highlights gaps in the evidence base, which future research and better measures for assessing data use should attempt to address.

A realist systematic review of stigma reduction interventions for HIV prevention and care continuum outcomes among men who have sex with men.

While stigma associated with human immunodeficiency virus (HIV) infection among men who have sex with men (MSM) is well recognized, there remains relatively limited intervention data on effective stigma reduction strategies. This systematic review was conducted to highlight the mechanisms through which sexual and HIV stigma is reduced in relation to HIV prevention and care engagement. Search of PubMed and Scopus resulted in 11 tested interventions to include in our preliminary model constructed from programme frameworks and recommendations. We refined the preliminary programme theory to identify whether, why, or how mitigation strategies produce observed outcomes. Our review showed that the interventions produced stigma reduction through three groups of mechanisms: (1) Self-acceptance, leadership, and motivational activation for behaviour change from intrapersonal strategies, such as education and mobile health strategies, which intervene on internalized and anticipated stigma; (2) socialization, knowledge sharing, and social empowerment from interpersonal strategies, such as peer support and training for care providers; and (3) community introspection, self-reflection, and humanistic activation from structural strategies such as community leaders' sensitization, which intervene on both anticipated and enacted stigma. Interventions mechanisms act complementarily and can be activated in different contexts in which MSM exposed to and infected with HIV are living.

Oral health interventions for people living with mental disorders: protocol for a realist systematic review

BackgroundThe increasing number of people who experience mental disorders is a global problem. People with mental disorders have high rates of co-morbidity and significantly poorer oral health outcomes than the general public. However, their oral health remains largely a hidden and neglected issue. A complex range of factors impact the oral health of this group. These include anxiety and dental phobia, dietary habits, including the heavy consumption of sugary drinks, substance misuse of tobacco, alcohol, and/or psychostimulants, the adverse orofacial side effects of anti-psychotic and anti-depression medications, and financial, geographic, and social barriers to accessing oral health care.MethodsThe aim of this realist systematic review is to (a) identify and synthesise evidence that explores oral health interventions for people living with mental disorders; (b) explore the context and mechanisms that have contributed to the success of interventions or the barriers and challenges; (c) produce program theories on causal, contextual and mechanistic factors to facilitate outcomes and (d) produce recommendations and guidelines to guide future oral health interventions for people with mental disorders at both the policy and practice level. Using a five-step process, that incorporates primary data collection from key stakeholders, a beginning theoretical framework will be developed to describe contextual and mechanistic factors and how they might impact on the success or failure of oral health interventions for people with mental disorders. Key database searches will be conducted, with data extraction focused on the factors that might have impacted on intervention implementation and outcomes. Quality appraisal of studies will occur, and the theoretical framework will be populated with extracted data. Stakeholder input will support the development and refinement of a theory on oral health interventions for people with mental disorders.DiscussionThis will be the first review to take a realist approach to explore the broad scope of causal factors that impact on the success or failure of oral health interventions for people with mental disorders. The approach includes extensive stakeholder engagement and will advance realist systematic review methodology. Review outcomes will be important in guiding policy and practice to ensure oral health interventions better meet the needs of people with mental disorders.Systematic review registration This review protocol is registered with PROSPERO (Number) 155969.

Clinical teaching unit design: a realist systematic review protocol of evidence-based practices for clinical education and health service delivery

IntroductionThe clinical teaching unit (CTU) has emerged as a near-ubiquitous model of clinical education across Canadian and international medical schools since it was first proposed over 50 years ago. However,...

Implementation Strategies to Enhance the Implementation of eHealth Programs for Patients With Chronic Illnesses: Realist Systematic Review.

BackgroundThere is growing evidence of the positive effects of electronic health (eHealth) interventions for patients with chronic illness, but implementation of such interventions into practice is challenging. Implementation strategies that potentially impact implementation outcomes and implementation success have been identified. Which strategies are actually used in the implementation of eHealth interventions for patients with chronic illness and which ones are the most effective is unclear.ObjectiveThis systematic realist review aimed to summarize evidence from empirical studies regarding (1) which implementation strategies are used when implementing eHealth interventions for patients with chronic illnesses living at home, (2) implementation outcomes, and (3) the relationship between implementation strategies, implementation outcomes, and degree of implementation success.MethodsA systematic literature search was performed in the electronic databases MEDLINE, Embase, PsycINFO, Scopus, Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Library. Studies were included if they described implementation strategies used to support the integration of eHealth interventions into practice. Implementation strategies were categorized according to 9 categories defined by the Expert Recommendations for Implementing Change project: (1) engage consumers, (2) use evaluative and iterative strategies, (3) change infrastructure, (4) adapt and tailor to the context, (5) develop stakeholder interrelationships, (6) use financial strategies, (7) support clinicians, (8) provide interactive assistance, and (9) train and educate stakeholders. Implementation outcomes were extracted according to the implementation outcome framework by Proctor and colleagues: (1) acceptability, (2) adoption, (3) appropriateness, (4) cost, (5) feasibility, (6) fidelity, (7) penetration, and (8) sustainability. Implementation success was extracted according to the study authors’ own evaluation of implementation success in relation to the used implementation strategies.ResultsThe implementation strategies management support and engagement, internal and external facilitation, training, and audit and feedback were directly related to implementation success in several studies. No clear relationship was found between the number of implementation strategies used and implementation success.ConclusionsThis is the first review examining implementation strategies, implementation outcomes, and implementation success of studies reporting the implementation of eHealth programs for patients with chronic illnesses living at home. The review indicates that internal and external facilitation, audit and feedback, management support, and training of clinicians are of importance for eHealth implementation. The review also points to the lack of eHealth studies that report implementation strategies in a comprehensive way and highlights the need to design robust studies focusing on implementation strategies in the future.Trial RegistrationPROSPERO CRD42018085539; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=85539

Multiteam systems in an agile environment: a realist systematic review

Purpose The purpose of this paper is to highlight a collaborative effort between academia (University of North Texas, Team Sciences) and practice (Toyota Connected (TC)). This study concentrated on current problems that had been experienced by TC: How to structure and manage multiteam systems (MTSs)? Design/methodology/approach This research study utilized a realist systematic review to address an existing problem by working collaboratively with TC and academia. This collaboration involved problem identification, the development of research questions and a full systematic review guided by the research questions. Findings This realist systematic review merged the literature with current practices at TC in an effort to gather evidence to support the best method of structuring and managing MTSs. The findings include a leadership structure that incorporates both shared leadership (bottom-up) and existing hierarchical structures (top-down). Practical implications The MTS models presented in this study provide new models for organizations/manufacturers/industries to use as a guide when structuring their MTSs. Originality/value This study provides an example of a collaborative research effort between practice and academia using a realist systematic review. The paper also provides some multiteam system models that could be implemented and tested in different organizations. Also, new responsibilities and roles for scrum and MTSs are presented as a new method of achieving Agile.

Participation of children with disabilities in school: A realist systematic review of psychosocial and environmental factors.

BackgroundIn order to make informed decisions about how best to support children and young people with disabilities, effective strategies that facilitate active and meaningful participation in school are required. Clinical factors, diagnosis or impairments somewhat helpful in determining what should be provided in interventions. However, clinical factors alone will not offer a clear view of how to support participation. It is helpful then to look at wider psychosocial and environmental factors. The aim of this review was to synthesise evidence of psychosocial and environmental factors associated with school participation of 4–12 year old children with disabilities to inform the development of participation-fostering interventions.MethodsA systematic search and synthesis using realist methods was conducted of published research. Papers had to include consideration of psychosocial and/or environment factors for school participation of children with disabilities. The review was completed in accordance with the Realist and Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) and Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Papers were identified via Boolean search of the electronic databases MEDLINE, CINAHL, PhycINFO and ERIC (January 2006-October 2018). Appraisal focussed on contributions in terms of whether the articles are appropriate for the review (relevance) and research quality (rigour). Data were analyzed using content and thematic analysis methods using a realist framework. A narrative synthesis of results was reported.Results and implicationsWe identified 1828 papers in the initial search. Seventy two papers were included in the final synthesis. Synthesis of findings led to three overarching mechanisms representing psychosocial factors for children (1) identity (2) competence and (3) experience of mind and body. Environmental aspects (context) compromised five interrelated areas: (1) structures and organization, (2) peers, (3) adults, (4) space and (5) objects. Our synthesis provides insights on how professionals may organize efforts to improve children’s participation. Consideration of these findings will help to proactively deal with suboptimal participation outcomes. Development of theoretically determined assessments and interventions for management of school participation are now required.

Digital engineering potential in addressing causes of construction accidents

With the emergence of digital engineering in the construction context, significant opportunities have arisen for safer project execution. Several studies in recent years have described various applications of digital engineering to improve safety performance. However, what is missing is a systematic review that shows the direct links between the potential of these approaches and how they address the causes of construction accidents. This study is an attempt to fill this gap by conducting a realist systematic review of the literature published since 2012. The study draws from the Loughborough Construction Accident Causation (ConAC) model to create a comprehensive list of accident causes and relates these causes to the identified digital engineering potential, as reflected in the literature. This approach identifies the research gaps and neglected research domains, particularly six endemic problems, within the current digital engineering literature pertaining to safety, while introducing future areas associated with the identified gaps. This study provides useful insights to investigators who gain direction towards the top priorities for future research. In practical terms, the study collates and presents various areas of potential within digital engineering to address the causes of accidents on construction sites, providing a concise source of knowledge for practitioners.

Development of programme theory for integration of service user and caregiver involvement in mental health system strengthening: protocol for realist systematic review

BackgroundThere is international recognition of the need for service user and caregiver involvement in mental health system strengthening. However, little is known about how best to integrate this approach into the mental healthcare system; what works to advance involvement, under what conditions, how and when does involvement bring added value, and how can it work in resource-poor settings in low and middle-income countries.ObjectiveTo describe the methodology for a realist systematic review protocol to synthesise the evidence to explain the contexts, outcomes, and underlying mechanisms for involvement of service users with severe mental health problems and their caregivers in mental healthcare policy-making and planning, advocacy, service development, monitoring and improvement.Methods/designsThe proposed realist systematic review will involve five steps: (i) clarifying the review scope, (ii) a systematic search for evidence, (iii) evidence appraisal and data extraction, (iv) data analysis, (v) synthesis of evidence and formation of revised programme theory. Inputs from a formative qualitative study, consultative Theory of Change meetings with key stakeholder groups, and scoping reviews will be used to identify candidate theory/theories that will guide the selection, appraisal and analysis of studies, and refine the Theory of Change model that will be piloted and evaluated. Synthesis of data will be undertaken using realist logic, constant comparison and thematic analysis. In a consultative meeting with stakeholders the Theory of Change model will then be situated with respect to relevant programme theories and adapted to incorporate the synthesized evidence of relevance to the local context. The finalized Theory of Change model will be piloted and evaluated in a primary health care setting in rural Ethiopia.DiscussionRealist review methodology has not been applied to the area of mental health service user involvement in low- and middle-income country settings. In this protocol, we describe how this contextualized approach will be applied to identify and refine a theory-driven and transferable model of involvement of service users, embedded in ongoing work in Ethiopia.Systematic review registration PROSPERO CRD42018084595

Improving food environments and tackling obesity: A realist systematic review of the policy success of regulatory interventions targeting population nutrition.

BackgroundThis systematic review (PROSPERO: CRD42015025276) employs a realist approach to investigate the effect of “real-world” policies targeting different aspects of the food environment that shape individual and collective nutrition.ObjectivesWe were interested in assessing intermediate outcomes along the assumed causal pathway to “policy success”, in addition to the final outcome of changed consumption patterns.Data sourcesWe performed a search of 16 databases through October 2015, with no initial restriction by language.Study eligibility criteriaWe included all publications that reported the effect of statutory provisions aimed at reducing the consumption of energy-dense foods and beverages in the general population. We allowed all methodological approaches that contained some measure of comparison, including studies of implementation progress.Study appraisal and synthesis methodsWe reviewed included studies using the appraisal tools for pre-post and observational studies developed by the National Heart, Lung, and Blood Institute. Given the considerable heterogeneity in interventions assessed, study designs employed, and outcome measures reported, we opted for a narrative synthesis of results.Results and implicationsResults drawn from 36 peer-reviewed articles and grey literature reports demonstrated that isolated regulatory interventions can improve intermediate outcomes, but fail to affect consumption at clinically significant levels. The included literature covered six different types of interventions, with 19 studies reporting on calorie posting on chain restaurant menus. The large majority of the identified interventions were conducted in the US. Early results from recent taxation measures were published after the review cut-off date but these suggested more favorable effects on consumption levels. Nevertheless, the evidence assessed in this review suggests that current policies are generally falling short of anticipated health impacts.

A realist review of the partograph: when and how does it work for labour monitoring?

BackgroundThe partograph (or partogram) is recommended by the World Health Organisation (WHO), for monitoring labour wellbeing and progress. Concerns about limitations in the way the partograph is used in the clinical context and the potential impact on its effectiveness have led to this realist systematic review of partograph use.MethodsThis review aimed to answer two key questions, 1) What is it about the partograph that works (or does not work); for whom does it work; and in what circumstances? 2) What are the essential inputs required for the partograph to work? A comprehensive search strategy encompassed key databases; including papers of varying methodologies. Papers were selected for inclusion if the focus of the paper was the partograph and related to context, mechanism or outcome. Ninety five papers were included for data synthesis. Two authors completed data extraction and synthesis.ResultsThe evidence synthesis relates the evidence to identified theories of health worker acceptability, health system support, effective referral systems, human resources and health worker competence, highlighting barriers and facilitators.ConclusionsThis first comprehensive realist synthesis of the partograph, provides the international community of maternity clinicians with a picture of potential issues and solutions related to successful labour recording and management, which is also translatable to other monitoring approaches.

Implementing health promotion programmes in schools: a realist systematic review of research and experience in the United Kingdom.

BackgroundSchools have long been viewed as a good setting in which to encourage healthy lifestyles amongst children, and schools in many countries aspire to more comprehensive, integrated approaches to health promotion. Recent reviews have identified evidence of the effects of school health promotion on children’s and young people’s health. However, understanding of how such programmes can be implemented in schools is more limited.MethodsWe conducted a realist review to identify the conditions and actions which lead to the successful implementation of health promotion programmes in schools. We used the international literature to develop programme theories which were then tested using evaluations of school health promotion programmes conducted in the United Kingdom (UK). Iterative searching and screening was conducted to identify sources and clear criteria applied for appraisal of included sources. A review advisory group comprising educational and public health practitioners, commissioners, and academics was established at the outset.ResultsIn consultation with the review advisory group, we developed four programme theories (preparing for implementation, initial implementation, embedding into routine practice, adaptation and evolution); these were then refined using the UK evaluations in the review. This enabled us to identify transferable mechanisms and enabling and constraining contexts and investigate how the operation of mechanisms differed in different contexts. We also identified steps that should be taken at a senior level in relation to preparing for implementation (which revolved around negotiation about programme delivery) and initial implementation (which centred on facilitation, support, and reciprocity—the latter for both programme deliverers and pupils). However, the depth and rigour of evidence concerning embedding into routine practice and adaptation and evolution was limited.ConclusionsOur findings provide guidance for the design, implementation, and evaluation of health promotion in schools and identify the areas where further research is needed.Electronic supplementary materialThe online version of this article (doi:10.1186/s13012-015-0338-6) contains supplementary material, which is available to authorized users.

Key characteristics of successful quality improvement curricula in physician education: a realist review
