RESUMO

BACKGROUND: Dementia is a leading, global public health challenge. Recent evidence supporting a decrease in age-specific incidence of dementia in high-income countries (HICs) suggests that risk reduction is possible through improved life-course public health. Despite this, efforts to date have been heavily focused on individual-level approaches, which are unlikely to significantly reduce dementia prevalence or inequalities in dementia. In order to inform policy, we identified the population-level interventions for dementia risk reduction with the strongest evidence base. METHODS: We did this complex, multistage, evidence review to summarise the empirical, interventional evidence for population-level interventions to reduce or control each of the 12 modifiable life-course risk factors for dementia identified by the Lancet commission. We conducted a series of structured searches of peer-reviewed and grey literature databases (eg, Medline, Trip database, Cochrane library, Campbell Collaboration, the WHO, and Google Scholar), in January, March, and June, 2023. Search terms related to risk factors, prevention, and population-level interventions, without language restrictions. We extracted evidence of effectiveness and key contextual information to aid consideration and implementation of interventions by policymakers. We performed a narrative synthesis and evidence grading, and we derived a population-level dementia risk reduction intervention framework, structured by intervention type. This study is registered with PROSPERO, ID:CRD42023396193. FINDINGS: We identified clear and consistent evidence for the effectiveness of 26 population-level interventions to reduce the prevalence of nine of the risk factors, of which 23 have been empirically evaluated in HICs, and 16 in low-income and middle-income countries. We identified interventions that acted through fiscal levers (n=5; eg, removing primary school fees), marketing or advertising levers (n=5; eg, plain packaging of tobacco products), availability levers (n=8; eg, cleaner fuel replacement programmes for cooking stoves), and legislative levers (n=8; eg, mandated provision of hearing protective equipment at noisy workplaces). We were not able to recommend any interventions for diabetes (other than indirectly through action on obesity and physical inactivity), depression, or social isolation. INTERPRETATION: This complex evidence review provides policymakers and public health professionals with an evidence-based framework to help develop and implement population-level approaches for dementia risk reduction that could significantly reduce the population's risk of dementia and reduce health inequalities. FUNDING: None.

RESUMO

INTRODUCTION: How to communicate effectively with adolescent and young adults with cancer (AYACs) is a research priority. In a UK-wide survey of young people with cancer's research priorities, communication was a striking cross-cutting theme. It is increasingly recognised that AYACs have experiences and communication needs that differ significantly from those of younger children and older adults. The purpose of this review is to explore the features of effective clinical communication with AYACs. METHODS: A literature search was undertaken to identify and map the available evidence using a broad scope to get an overview of the pertinent literature, identify knowledge gaps and clarify concepts. The searches yielded 5825 records, generating 4040 unique articles. These were screened and 71 full articles were read by four researchers with disagreements resolved by discussion leaving 29 included articles. Narrative synthesis was undertaken in relation to each of the research questions. RESULTS: Three key themes were identified: being an adolescent/young adult, supporters, and healthcare professionals (HCPs). AYACs need to feel that HCPs understand their unique perspective. They want to be involved, this changes over time and in different contexts. Supporters are a central tenet, are most often parents and undertake several roles which are not always universally supportive. HCPs enable involvement of AYACs, and this needs to be actively promoted. AYACs preference for their level of involvement requires continual assessment. The three themes are interlinked and exist within the wider scope of the triadic encounter and cancer experience. CONCLUSION: Supporters, most often parents were a key feature across the data and were seemingly paradoxical in nature. Triadic communication, the presence of a third person, is a central tenet of communication with AYACs and we propose a conceptual model to represent the nuances, components, and facets of this complex communication.

RESUMO

BACKGROUND: Trauma accounts for a huge burden of disease worldwide. Trauma systems have been implemented in multiple countries across the globe, aiming to link and optimise multiple aspects of the trauma care pathway, and while they have been shown to reduce overall mortality, much less is known about their cost-effectiveness and impact on morbidity. METHODS: We performed a systematic review to explore the impact the implementation of a trauma system has on morbidity, quality of life and economic outcomes, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All comparator study types published since 2000 were included, both retrospective and prospective in nature, and no limits were placed on language. Data were reported as a narrative review. RESULTS: Seven articles were identified that met the inclusion criteria, all of which reported a pre-trauma and post-trauma system implementation comparison in high-income settings. The overall study quality was poor, with all studies demonstrating a severe risk of bias. Five studies reported across multiple types of trauma patients, the majority describing a positive impact across a variety of morbidity and health economic outcomes following trauma system implementation. Two studies focused specifically on traumatic brain injury and did not demonstrate any impact on morbidity outcomes. DISCUSSION: There is currently limited and poor quality evidence that assesses the impact that trauma systems have on morbidity, quality of life and economic outcomes. While trauma systems have a fundamental role to play in high-quality trauma care, morbidity and disability data can have large economic and cultural consequences, even if mortality rates have improved. The sociocultural and political context of the surrounding healthcare infrastructure must be better understood before implementing any trauma system, particularly in resource-poor and fragile settings. PROSPERO REGISTRATION NUMBER: CRD42022348529 LEVEL OF EVIDENCE: Level III.

RESUMO

OBJECTIVE: To explore the available evidence on hyperosmolar therapies(HT) in mild and moderate traumatic brain injury(TBI) and to evaluate the effects on outcomes.A scoping review was conducted according to the Joanna Briggs Institute methodology. Inclusion criteria: (a)randomized controlled trials(RCTs), prospective and retrospective cohort studies and case-control studies; (b)all-ages mild and moderate TBIs; (c)HT administration; (d)functional outcomes recorded; (e)comparator group. RESULTS: From 4424 records, only 3 respected the inclusion criteria. In a retrospective cohort study of adult moderate TBIs, the Glasgow Coma Scale(GCS) remained the same at 48 hours in those treated with hypertonic saline(HTS) while it worsened in the non-treated. A trend toward increased pulmonary infections and length of stay was found. In an RCT of adult severe and moderate TBIs, moderate TBIs treated with HTS showed a trend toward better secondary outcomes than standard care alone, with similar odds of adverse effects. An RCT enrolling children with mild TBI found a significant improvement in concussive pain immediately after HTS administration and after 2-3 days. No adverse events occurred. CONCLUSIONS: A gap in the literature about HTs' role in mild and moderate TBI was found. Some benefits may exist with limited side effects and further studies are desirable.

RESUMO

BACKGROUND: Degenerative cervical myelopathy (DCM) is a recently proposed umbrella term for symptomatic cervical spinal cord compression secondary to degeneration of the spine. Currently literature searching for DCM is challenged by the inconsistent uptake of the term 'DCM' with many overlapping keywords and numerous synonyms. OBJECTIVES: Here, we adapt our previous Ovid medline search filter for the Ovid embase database, to support comprehensive literature searching. Both embase and medline are recommended as a minimum for systematic reviews. METHODS: References contained within embase identified in our prior study formed a 'development gold standard' reference database (N = 220). The search filter was adapted for embase and checked against the reference database. The filter was then validated against the 'validation gold standard'. RESULTS: A direct translation was not possible, as medline indexing for DCM and the keywords search field were not available in embase. We also used the 'focus' function to improve precision. The resulting search filter has 100% sensitivity in testing. DISCUSSION AND CONCLUSION: We have developed a validated search filter capable of retrieving DCM references in embase with high sensitivity. In the absence of consistent terminology and indexing, this will support more efficient and robust evidence synthesis in the field.

RESUMO

OBJECTIVES: uncertainty pervades the complex illness trajectories experienced by older adults with multimorbidity. Uncertainty is experienced by older people, their informal carers and professionals providing care, yet is incompletely understood. We aimed to identify and synthesise systematically the experience of uncertainty in advanced multimorbidity from patient, carer and professional perspectives. DESIGN: systematic literature review of published and grey qualitative literature from 9 databases (Prospero CRD 42021227480). PARTICIPANTS: older people with advanced multimorbidity, and informal carers/professionals providing care to this group. Exclusion criteria: early multimorbidity, insufficient focus on uncertainty. ANALYSIS: weight-of-evidence assessment was used to appraise included articles. We undertook thematic synthesis of multi-perspective experiences and response to uncertainty. RESULTS: from 4,738 unique search results, we included 44 articles relating to 40 studies. 22 focused on patient experiences of uncertainty (n = 460), 15 on carer experiences (n = 197), and 19 on health professional experiences (n = 490), with 10 exploring multiple perspectives. We identified a shared experience of 'Total Uncertainty' across five domains: 'appraising and managing multiple illnesses'; 'fragmented care and communication'; 'feeling overwhelmed'; 'uncertainty of others' and 'continual change'. Participants responded to uncertainty by either active (addressing, avoiding) or passive (accepting) means. CONCLUSIONS: the novel concept of 'Total Uncertainty' represents a step change in our understanding of illness experience in advanced multimorbidity. Patients, carers and health professionals experienced uncertainty in similar domains, suggesting a shared understanding is feasible. The domains of total uncertainty form a useful organising framework for health professionals caring for older adults with multimorbidity.

RESUMO

BACKGROUND: Identifying how unwarranted variations in healthcare delivery arise is challenging. Experimental vignette studies can help, by isolating and manipulating potential drivers of differences in care. There is a lack of methodological and practical guidance on how to design and conduct these studies robustly. The aim of this study was to locate, methodologically assess, and synthesise the contribution of experimental vignette studies to the identification of drivers of unwarranted variations in healthcare delivery. METHODS: We used a scoping review approach. We searched MEDLINE, Embase, Web of Science and CINAHL databases (2007-2019) using terms relating to vignettes and variations in healthcare. We screened title/abstracts and full text to identify studies using experimental vignettes to examine drivers of variations in healthcare delivery. Included papers were assessed against a methodological framework synthesised from vignette study design recommendations within and beyond healthcare. RESULTS: We located 21 eligible studies. Study participants were almost exclusively clinicians (18/21). Vignettes were delivered via text (n = 6), pictures (n = 6), video (n = 6) or interactively, using face-to-face, telephone or online simulated consultations (n = 3). Few studies evaluated the credibility of vignettes, and many had flaws in their wider study design. Ten were of good methodological quality. Studies contributed to understanding variations in care, most commonly by testing hypotheses that could not be examined directly using real patients. CONCLUSIONS: Experimental vignette studies can be an important methodological tool for identifying how unwarranted variations in care can arise. Flaws in study design or conduct can limit their credibility or produce biased results. Their full potential has yet to be realised.

RESUMO

BACKGROUND: Diagnostic uncertainty (DU) in primary care is ubiquitous, yet no review has specifically examined its communication, or the associated ethical issues. OBJECTIVES: To identify what is known about the communication of DU in primary care and the associated ethical issues. METHODS: Systematic review, critical interpretive synthesis and ethical analysis of primary research published worldwide. Medline, Embase, Web of Science and SCOPUS were searched for papers from 1988 to 2020 relating to primary care AND diagnostic uncertainty AND [ethics OR behaviours OR communication]. Critical interpretive synthesis and ethical analysis were applied to data extracted. RESULTS: Sixteen papers met inclusion criteria. Although DU is inherent in primary care, its communication is often limited. Evidence on the effects of communicating DU to patients is mixed; research on patient perspectives of DU is lacking. The empirical literature is significantly limited by inconsistencies in how DU is defined and measured. No primary ethical analysis was identified; secondary analysis of the included papers identified ethical issues relating to maintaining patient autonomy in the face of clinical uncertainty, a gap in considering the direct effects of (not) communicating DU on patients, and considerations regarding over-investigation and justice. CONCLUSIONS: This review highlights significant gaps in the literature: there is a need for explicit ethical and patient-centred empirical analyses on the effects of communicating DU, and research directly examining patient preferences for this communication. Consensus on how DU should be defined, and greater research into tools for its measurement, would help to strengthen the empirical evidence base.

RESUMO

STUDY DESIGN: Systematic review. OBJECTIVES: To evaluate the impact of cannabinoids on neurobehavioral outcomes in preclinical models of nontraumatic and traumatic spinal cord injury (SCI), with the aim of determining suitability for clinical trials involving SCI patients. METHODS: A systematic search was performed in MEDLINE and Embase databases, following registration with PROPSERO (CRD42019149671). Studies evaluating the impact of cannabinoids (agonists or antagonists) on neurobehavioral outcomes in preclinical models of nontraumatic and traumatic SCI were included. Data extracted from relevant studies, included sample characteristics, injury model, neurobehavioural outcomes assessed and study results. PRISMA guidelines were followed and the SYRCLE checklist was used to assess risk of bias. RESULTS: The search returned 8714 studies, 19 of which met our inclusion criteria. Sample sizes ranged from 23 to 390 animals. WIN 55,212-2 (n = 6) and AM 630 (n = 8) were the most used cannabinoid receptor agonist and antagonist respectively. Acute SCI models included traumatic injury (n = 16), ischaemia/reperfusion injury (n = 2), spinal cord cryoinjury (n = 1) and spinal cord ischaemia (n = 1). Assessment tools used assessed locomotor function, pain and anxiety. Cannabinoid receptor agonists resulted in statistically significant improvement in locomotor function in 9 out of 10 studies and pain outcomes in 6 out of 6 studies. CONCLUSION: Modulation of the endo-cannabinoid system has demonstrated significant improvement in both pain and locomotor function in pre-clinical SCI models; however, the risk of bias is unclear in all studies. These results may help to contextualise future translational clinical trials investigating whether cannabinoids can improve pain and locomotor function in SCI patients.

RESUMO

INTRODUCTION: Nasal packing is the mainstay of epistaxis management; however, packs cause patient discomfort and can lead to hospital admission. Absorbable haemostats provide clotting factors or act as a substrate to stimulate clotting and represent a potential treatment alternative. A systematic review was performed to evaluate the efficacy of topical haemostats in the management of epistaxis. METHODS: A systematic literature search of 7 databases was performed. Only eligible randomised controlled trials (RCTs) and observational studies were included. The primary outcome was short-term haemostatic success (<7 days). Secondary outcomes included long-term haemostatic control (no rebleeding 7-30 days), patient discomfort and adverse effects. Meta-analysis was performed where possible. RESULTS: Of 2249 records identified, 12 were included in the qualitative synthesis and 4 RCTs were included in meta-analysis. The following haemostats were reported: gelatin-thrombin matrix (n = 8), aerosolised/gel tranexamic acid (n = 1), cellulose agents (n = 2) and fibrin sealants (n = 1). Studies involving tranexamic acid on removable delivery devices (eg, pledgets) were excluded. There was heterogeneity in outcome measures and inclusion criteria (coagulopathies/anticoagulants were excluded in 3 RCTs and 2 observational studies). The short-term haemostatic success varied between studies (13.9% to 100%). No significant post-procedural complications were reported. The meta-analysis favoured absorbable haemostatic agent versus packing (risk ratio 1.20; 95% confidence interval 1.05 to 1.37; P = .007). The risk of bias across all studies was moderate to high. CONCLUSIONS: The evidence suggests haemostatic agents are effective at managing acute epistaxis when compared with nasal packing. More data are required before recommendations can be made regarding management in patients on anticoagulants.

RESUMO

BACKGROUND: Systematic reviews are vital to the pursuit of evidence-based medicine within healthcare. Screening titles and abstracts (T&Ab) for inclusion in a systematic review is an intensive, and often collaborative, step. The use of appropriate tools is therefore important. In this study, we identified and evaluated the usability of software tools that support T&Ab screening for systematic reviews within healthcare research. METHODS: We identified software tools using three search methods: a web-based search; a search of the online "systematic review toolbox"; and screening of references in existing literature. We included tools that were accessible and available for testing at the time of the study (December 2018), do not require specific computing infrastructure and provide basic screening functionality for systematic reviews. Key properties of each software tool were identified using a feature analysis adapted for this purpose. This analysis included a weighting developed by a group of medical researchers, therefore prioritising the most relevant features. The highest scoring tools from the feature analysis were then included in a user survey, in which we further investigated the suitability of the tools for supporting T&Ab screening amongst systematic reviewers working in medical research. RESULTS: Fifteen tools met our inclusion criteria. They vary significantly in relation to cost, scope and intended user community. Six of the identified tools (Abstrackr, Colandr, Covidence, DRAGON, EPPI-Reviewer and Rayyan) scored higher than 75% in the feature analysis and were included in the user survey. Of these, Covidence and Rayyan were the most popular with the survey respondents. Their usability scored highly across a range of metrics, with all surveyed researchers (n = 6) stating that they would be likely (or very likely) to use these tools in the future. CONCLUSIONS: Based on this study, we would recommend Covidence and Rayyan to systematic reviewers looking for suitable and easy to use tools to support T&Ab screening within healthcare research. These two tools consistently demonstrated good alignment with user requirements. We acknowledge, however, the role of some of the other tools we considered in providing more specialist features that may be of great importance to many researchers.

RESUMO

BACKGROUND: Internationally, patient access to notes is increasing. This has been driven by respect for patient autonomy, often recognised as a primary tenet of medical ethics: patients should be able to access their records to be fully engaged with their care. While research has been conducted on the impact of patient access to outpatient and primary care records and to patient portals, there is no such review looking at access to hospital medical records in real time, nor an ethical analysis of the issues involved in such a change in process. METHODS: This study employed a systematic review framework in two stems, to integrate literature identified from two searches: Medline, CINAHL and Scopus databases were conducted, (for (1) hospitalised patients, patient access to records and its effects on communication and trust within the doctor-patient relationship; and (2) patient access to medical records and the ethical implications identified). The qualitative and quantitative results of both searches were integrated and critically analysed. RESULTS: 3954 empirical and 4929 ethical studies were identified; 18 papers representing 16 studies were identified for review (12 empirical and 6 ethical). The review reveals a consensus that our current approach to giving information to patients - almost exclusively verbally - is insufficient; that patient access to notes is a welcome next step for patient-centred care, but that simply allowing full access, without explanation or summary, is also insufficient. Several ethical implications need to be considered: increased information could improve patient trust and knowledge but might transfer an (unwelcome) sense of responsibility to patients; doctors and patients have conflicting views on how much information should be shared and when; sharing written information might increase the already significant disparity in access to health care, and have unforeseen opportunity costs. The impact on medical practice of sharing notes in real time will also need to be evaluated. CONCLUSIONS: The review presents encouraging data to support patient access to medical notes. However, sharing information is a critical part of clinical practice; changing how it is done could have significant empirical and ethical impacts; any changes should be carefully evaluated.

RESUMO

STUDY DESIGN: Systematic review. INTRODUCTION: Children with cerebral palsy (CP) may have limited use of their hands for functional activities and for fine motor skills. Virtual reality (VR) is a relatively new and innovative approach to facilitate hand function in children with CP. PURPOSE OF THE STUDY: The primary purpose of this study was to determine the effectiveness of VR as an intervention to improve hand function in children with CP compared to either conventional physiotherapy or other therapeutic interventions. The secondary purpose was to classify the outcomes evaluated according to the International Classification of Functioning, Disability and Health (ICF) dimensions. METHODS: A International prospective register of systematic reviews (PROSPERO)-registered literature search was carried out in August 2015 in MEDLINE, CINAHL, ERIC, HealthSTAR, AMED, BNI, Embase, PsycINFO, PEDro, Cochrane Central Register, DARE, OTSeeker, REHABDATA, HaPI, CIRRIE, and Scopus. PRISMA guidelines were followed. Only randomized controlled trials (RCTs) were included, and their methodological qualities were examined using the Cochrane collaboration's risk of bias (RoB) tool. A narrative synthesis was performed. RESULTS: The 6 RCTs published on this topic provide conflicting results. Four studies reported improved hand function (2 low RoB, 1 high RoB, and 1 unclear RoB), whereas 2 studies reported no improvement. All of the RCTs reported the activity element of ICF, but no study explicitly described the effect of VR intervention based on the ICF model. CONCLUSION: The role of VR ti imrpove hand fucntion in children with CP is unclear due to limited evidence; use as an adjunct has some support.

RESUMO

BACKGROUND: Degenerative cervical myelopathy (DCM) is a common condition with many unmet clinical needs. Pooled analysis of studies is an important tool for advancing medical understanding. This process starts with a systematic search of the literature. Identification of studies in DCM is challenged by a number of factors, including non-specific terminology and index terms. Search filters or HEDGEs, are search strings developed and validated to optimise medical literature searches. We aimed to develop a search filter for DCM for the MEDLINE database. METHODS: The diagnostic test assessment framework of a "development dataset" and seperate "validation dataset" was used. The development dataset was formed by hand searching four leading spinal journals (Spine, Journal of Neurosurgery Spine, Spinal Cord and Journal of Spinal Disorders and Techniques) in 2005 and 2010. The search filter was initially developed focusing on sensitivity and subsequently refined using NOT functions to improve specificity. One validation dataset was formed from DCM narrative and systematic review articles and the second, articles published in April of 1989, 1993, 1997, 2001, 2005, 2009, 2013 and 2017 retrieved via the search MeSH term 'Spine'. Metrics of sensitivity, specificity, precision and accuracy were used to test performance. RESULTS: Hand searching identified 77/1094 relevant articles for 2005 and 55/1199 for 2010. We developed a search hedge with 100% sensitivity and a precision of 30 and 29% for the 2005 and 2010 development datasets respectively. For the selected time periods, EXP Spine returned 2113 publications and 30 were considered relevant. The search filter identified all 30 relevant articles, with a specificity of 94% and precision of 20%. Of the 255 references listed in the narrative index reviews, 225 were indexed in MEDLINE and 165 (73%) were relevant articles. All relevant articles were identified and accuracy ranged from 67 to 97% over the three reviews. Of the 42 articles returned from 3 recent systematic reviews, all were identified by the filter. CONCLUSIONS: We have developed a highly sensitive hedge for the research of DCM. Whilst precision is similarly low as other hedges, this search filter can be used as an adjunct for DCM search strategies.

RESUMO

BACKGROUND: Network meta-analysis (NMA) allows for the estimation of comparative effectiveness of treatments that have not been studied in head-to-head trials; however, relative treatment effects for all interventions can only be derived where available evidence forms a connected network. Head-to-head evidence is limited in many disease areas, regularly resulting in disconnected evidence structures where a large number of treatments are available. This is also the case in the evidence of treatments for relapsed or refractory multiple myeloma. METHODS: Randomised controlled trials (RCTs) identified in a systematic literature review form two disconnected evidence networks. Standard Bayesian NMA models are fitted to obtain estimates of relative effects within each network. Observational evidence was identified to fill the evidence gap. Single armed trials are matched to act as each other's control group based on a distance metric derived from covariate information. Uncertainty resulting from including this evidence is incorporated by analysing the space of possible matches. RESULTS: Twenty five randomised controlled trials form two disconnected evidence networks; 12 single armed observational studies are considered for bridging between the networks. Five matches are selected to bridge between the networks. While significant variation in the ranking is observed, daratumumab in combination with dexamethasone and either lenalidomide or bortezomib, as well as triple therapy of carfilzomib, ixazomib and elozumatab, in combination with lenalidomide and dexamethasone, show the highest effects on progression free survival, on average. CONCLUSIONS: The analysis shows how observational data can be used to fill gaps in the existing networks of RCT evidence; allowing for the indirect comparison of a large number of treatments, which could not be compared otherwise. Additional uncertainty is accounted for by scenario analyses reducing the risk of over confidence in interpretation of results.

RESUMO

BACKGROUND: Transfers from hospital or 'hospice palliative care units' to care homes for end-of-life care are an increasingly common part of clinical practice but are a source of anxiety and distress for patients, relatives and healthcare professionals. AIM: To understand the experiences of patients discharged to care homes for end-of-life care. DESIGN: Systematic review and narrative synthesis of the UK literature concerning inpatient transfer from a hospital or hospice palliative care unit to a care home for end-of-life care. RESULTS: The published literature is very limited: only three papers and one conference abstract were identified, all of low quality using Gough's weight of evidence assessment. No papers examined transfer from hospital: all were of transfers from hospices and were retrospective case note reviews. Many patients were reported to have been negative or ambivalent about moving and experienced feelings of anxiety or abandonment when transferred. Relatives were often either vehemently opposed or ambivalent. Although some came to accept transfer, others reported the transfer to have seriously affected their loved one's quality of life and that the process of finding a care home had been traumatic. No studies investigated patients' views prospectively, the views of staff or the processes of decision-making. CONCLUSION: The UK literature is very limited, despite such transfers being an increasingly common part of clinical practice and a source of concern to patients, relatives and staff alike. Further research is urgently needed in this area, especially studies of patients themselves, in order to understand their experiences and views.

RESUMO

BACKGROUND: Large-scale improvement programmes are a frequent response to quality and safety problems in health systems globally, but have mixed impact. The extent to which they meet criteria for programme quality, particularly in relation to transparency of reporting and evaluation, is unclear. AIM: To identify large-scale improvement programmes focused on intrapartum care implemented in English National Health Service maternity services in the period 2010-2023, and to conduct a structured quality assessment. METHODS: We drew on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidance to inform the design and reporting of our study. We identified relevant programmes using multiple search strategies of grey literature, research databases and other sources. Programmes that met a prespecified definition of improvement programme, that focused on intrapartum care and that had a retrievable evaluation report were subject to structured assessment using selected features of programme quality. RESULTS: We identified 1434 records via databases and other sources. 14 major initiatives in English maternity services could not be quality assessed due to lack of a retrievable evaluation report. Quality assessment of the 15 improvement programmes meeting our criteria for assessment found highly variable quality and reporting. Programme specification was variable and mostly low quality. Only eight reported the evidence base for their interventions. Description of implementation support was poor and none reported customisation for challenged services. None reported reduction of inequalities as an explicit goal. Only seven made use of explicit patient and public involvement practices, and only six explicitly used published theories/models/frameworks to guide implementation. Programmes varied in their reporting of the planning, scope and design of evaluation, with weak designs evident. CONCLUSIONS: Poor transparency of reporting and weak or absent evaluation undermine large-scale improvement programmes by limiting learning and accountability. This review indicates important targets for improving quality in large-scale programmes.

RESUMO

BACKGROUND: There is increasing interest in self-referral and direct access as alternatives pathways to care to improve patient access to specialist services. The impact of these pathways on health inequalities is unknown. OBJECTIVES: The purpose of this systematic review is to explore the impact of self-referral and direct access pathways on inequalities in health care use. DESIGN: Three databases (Ovid Medline, Embase, Web of Science) and grey literature were systematically searched for articles from January 2000 to February 2023, reporting on self-referral and direct access pathways to care. Title and abstracts were screened against eligibility criteria to identify studies that evaluated the impact on health inequalities. Data were extracted from eligible studies after full text review and a quality assessment was performed using the ROBINS-I tool. RESULTS: The search strategy identified 2948 articles. Nineteen records were included, covering seven countries and six healthcare services. The impact of self-referral and direct access on inequalities was mixed, suggesting that the relationship is dependent on patient and system factors. Typically self-referral pathways and direct access pathways tend to widen health inequalities. White, younger, educated women from less deprived backgrounds are more likely to self-refer, exacerbating existing health inequalities. CONCLUSIONS: Self-referral pathways risk widening health inequalities. Further research is required to understand the context-dependent mechanisms by which this can occur, explore ways to mitigate this and even narrow health inequalities, as well as understand the impact on the wider healthcare system.
