Project description:Study Basis: This evidence map presents a summary of studies that addressed the effects of meditation on various clinical and health conditions. Meditation is a contemplative practice that has been used for the promotion of health, and the treatment of different conditions. Method: The study is based on the search of four electronic databases for the period 1994-November 2019 and includes systematic reviews, meta-analyses, meta-syntheses, and integrative reviews. 3iE evidence gap map was the methodology of choice, and AMSTAR 2 was used for the analyses. Tableau was used to graphically display the confidence level, number of reviews, health outcomes, and intervention effects. Results: This map encompasses 191 studies, with Mindfulness being the key word that retrieved the highest number of results. Several meditation techniques were evaluated in different contexts, and the confidence levels of 22 studies were high, 84 were moderate, and 82 were low. Two 2 meta-syntheses and 1 integrative review were also included. Most of the studies reported positive effects and a beneficial potential of the practice of meditation. Health outcomes were divided into five groups out of which mental health and vitality, and well-being and quality of life stood out with the largest number of studies. Conclusions: Meditation has been applied in different areas. This Evidence Map intends to be an easy visual tool to access valuable evidence-based information on this complementary therapy for patients, health professionals, and managers.

Project description:BackgroundAlthough the number of teledermatology studies is increasing, not all variables have been researched in equal depth, so there remains a lack of robust evidence for some teledermatology initiatives. This review describes the landscape of teledermatology research and identifies knowledge gaps and research needs. This evidence map can be used to inform clinicians about the current knowledge about teledermatology and guide researchers for future studies.MethodsOur evidence map was conducted according to the Campbell Collaboration checklist for evidence and gap maps. Eight databases were searched (CINAHL, Embase, PubMed, Scopus, Web of Science, Cochrane Library, JBI Database of Systematic Reviews and Implementation Reports, and OpenGray), and only included systematic reviews of teledermatology involving humans published in English; while excluding non-systematic reviews (i.e., abstracts, conference proceedings, editorials, commentaries, or letters). From 909 records, 14 systematic reviews published between 2004 and 2022 were included. Our analysis focused on the systematic reviews' characteristics, dermatological conditions studied, rate of overlap and quality assessment of primary studies reviewed, and main findings reported.ResultsTeledermatology was reportedly comparable with clinic dermatology and generally accepted by patients as a mode of care delivery for dermatological conditions. However, there are concerns about privacy, communication, completeness of information transmitted, familiarity with the technology, and technical problems. Healthcare professionals were generally satisfied with teledermatology but found telemedicine consultations longer than face-to-face consultations, and less confident in asynchronous teledermatology than conventional consultations. Teledermatology was reportedly more cost-effective than clinic dermatology; especially considering the distance traveled by patients, referral volume to teledermatology, and clinic dermatology costs. Although patients and providers are satisfied with teledermatology, face-to-face dermatology has higher diagnostic and management accuracy. Teledermatology was also used for training medical professionals. Regarding the validity and reliability of teledermatology outcome measures, no significant discussions were found.ConclusionsCOVID-19 spotlighted telemedicine in clinical care, and we must ensure telemedicine continually improves with robust research. Further research is necessary for establishing a standardized outcome set, enhancing accuracy, concordance, cost-effectiveness, and safety, comparing teledermatology with non-dermatologist care, examining its effectiveness in non-Western low and middle-income countries, and incorporating patient involvement for improved study design.Systematic review registrationhttps://www.researchregistry.com/ (Unique Identifying Number: reviewregistry878).

Project description:ObjectivesWe set out to map the quantitative and qualitative systematic review evidence available to inform the optimal prescribing of drugs that can cause dependency (benzodiazepines, opioids, non-benzodiazepine hypnotics, gabapentinoids and antidepressants). We also consider how this evidence can be used to inform decision-making in the patient care pathway for each type of medication.MethodsEight bibliographic databases were searched for the period 2010 to 2020. All included reviews were initially appraised using four items from the Collaboration for Environmental Evidence Synthesis Assessment Tool, with reviews that scored well on all items proceeding to full quality appraisal. Key characteristics of the reviews were tabulated, and each review was incorporated into an evidence and gap map based on a patient care pathway. The care pathway was based upon an amalgamation of existing NICE guidelines and feedback from clinical and patient stakeholders.ResultsWe identified 80 relevant reviews and displayed them in an evidence and gap map. The evidence included in these reviews was predominantly of low overall quality. Areas where systematic reviews have been conducted include barriers and facilitators to the deprescribing of drugs that may cause dependency, although we identified little evidence exploring the experiences or evaluations of specific interventions to promote deprescribing. All medications of interest, apart from gabapentinoids, were included in at least one review.ConclusionsThe evidence and gap map provides an interactive resource to support (i) policy developers and service commissioners to use evidence in the development and delivery of services for people receiving a prescription of drugs that may cause dependency, where withdrawal of medication may be appropriate, (ii) the clinical decision-making of prescribers and (iii) the commissioning of further research. The map can also be used to inform the commissioning of further systematic reviews. To address the concerns regarding the quality of the existing evidence based raised in this report, future reviews should be conducted according to best-practice guidelines. Systematic reviews focusing on evaluating interventions to promote deprescribing would be particularly beneficial, as would reviews focusing on addressing the paucity of evidence regarding the deprescription of gabapentinoids.

Project description:BackgroundThis study is to identify, summarise and synthesise literature on the causes of the evidence to practice gap for complex interventions in primary care.DesignThis study is a systematic review of reviews.MethodsMEDLINE, EMBASE, CINAHL, Cochrane Library and PsychINFO were searched, from inception to December 2013. Eligible reviews addressed causes of the evidence to practice gap in primary care in developed countries. Data from included reviews were extracted and synthesised using guidelines for meta-synthesis.ResultsSeventy reviews fulfilled the inclusion criteria and encompassed a wide range of topics, e.g. guideline implementation, integration of new roles, technology implementation, public health and preventative medicine. None of the included papers used the term "cause" or stated an intention to investigate causes at all. A descriptive approach was often used, and the included papers expressed "causes" in terms of "barriers and facilitators" to implementation. We developed a four-level framework covering external context, organisation, professionals and intervention. External contextual factors included policies, incentivisation structures, dominant paradigms, stakeholders' buy-in, infrastructure and advances in technology. Organisation-related factors included culture, available resources, integration with existing processes, relationships, skill mix and staff involvement. At the level of individual professionals, professional role, underlying philosophy of care and competencies were important. Characteristics of the intervention that impacted on implementation included evidence of benefit, ease of use and adaptability to local circumstances. We postulate that the "fit" between the intervention and the context is critical in determining the success of implementation.ConclusionsThis comprehensive review of reviews summarises current knowledge on the barriers and facilitators to implementation of diverse complex interventions in primary care. To maximise the uptake of complex interventions in primary care, health care professionals and commissioning organisations should consider the range of contextual factors, remaining aware of the dynamic nature of context. Future studies should place an emphasis on describing context and articulating the relationships between the factors identified here.Systematic review registrationPROSPERO CRD42014009410.

Project description:BackgroundDespite a considerable reduction in child mortality, nearly six million children under the age of five die each year. Millions more are poorly nourished and in many parts of the world, the quality of education remains poor. Children are at risk from multiple violations of their rights, including child labour, early marriage, and sexual exploitation. Research plays a crucial role in helping to close the remaining gaps in child well-being, yet the global evidence base for interventions to meet these challenges is mostly weak, scattered and often unusable by policymakers and practitioners. This mega-map encourages the generation and use of rigorous evidence on effective ways to improve child well-being for policy and programming.ObjectivesThe aim of this mega-map is to identify, map and provide an overview of the existing evidence synthesis on the interventions aimed at improving child well-being in low- and middle-income countries (LMICs).MethodsCampbell evidence and gap maps (EGMs) are based on a review of existing mapping standards (Saran & White, 2018) which drew in particular of the approach developed by 3ie (Snilstveit, Vojtkova, Bhavsar, & Gaarder, 2013). As defined in the Campbell EGM guidance paper; "Mega-map is a map of evidence synthesis, that is, systematic reviews, and does not include primary studies" (Campbell Collaboration, 2020). The mega-map on child well-being includes studies with participants aged 0-18 years, conducted in LMICs, and published from year 2000 onwards. The search followed strict inclusion criteria for interventions and outcomes in the domains of health, education, social work and welfare, social protection, environmental health, water supply and sanitation (WASH) and governance. Critical appraisal of included systematic reviews was conducted using "A Measurement Tool to Assess Systematic Reviews"-AMSTAR-2 rating scale (Shea, et al., 2017).ResultsWe identified 333 systematic reviews and 23 EGMs. The number of studies being published has increased year-on-year since 2000. However, the distribution of studies across World Bank regions, intervention and outcome categories are uneven. Most systematic reviews examine interventions pertaining to traditional areas of health and education. Systematic reviews in these traditional areas are also the most funded. There is limited evidence in social work and social protection. About 69% (231) of the reviews are assessed to be of low and medium quality. There are evidence gaps with respect to key vulnerable populations, including children with disabilities and those who belong to minority groups.ConclusionAlthough an increasing number of systematic reviews addressing child well-being topics are being published, some clear gaps in the evidence remain in terms of quality of reviews and some interventions and outcome areas. The clear gap is the small number of reviews focusing explicitly on either equity or programmes for disadvantaged groups and those who are discriminated against.

Project description:Connections between food security and nutrition (FSN) and mental health have been analytically investigated, but conclusions are difficult to draw given the breadth of literature. Furthermore, there is little guidance for continued research. We searched three databases for analytical studies linking FSN to mental health. Out of 30,896 records, we characterized and mapped 1945 studies onto an interactive Evidence and Gap Map (EGM). In these studies, anthropometry (especially BMI) and diets were most linked to mental health (predominantly depression). There were fewer studies on infant and young child feeding, birth outcomes, and nutrient biomarkers related to anxiety, stress, and mental well-being. Two-thirds of studies hypothesized FSN measures as the exposure influencing mental health outcomes. Most studies were observational, followed by systematic reviews as the next largest category of study. One-third of studies were carried out in low- and middle-income countries. This map visualizes the extent and nature of analytical studies relating FSN to mental health and may be useful in guiding future research.

Project description:Obstetric fistula is prevalent in low- and middle-income countries, with between 50,000 and 100,000 new cases each year. The World Health Organization aims to eradicate it by 2030 but a clear idea of the extant evidence is unavailable. This evidence map compiled evidence on treatments for obstetric fistula to identify potential knowledge gaps. The protocol for this work was published on the Open Science Framework (DOI: 10.17605/OSF.IO/H7J35). A survey was developed, piloted and distributed online through organisations with an interest in obstetric fistula and snowballing. Results informed the evidence map framework. Searches were run on MEDLINE, Embase, CENTRAL, Global Index Medicus and ScanMedicine on 16 February 2022 to identify potentially eligible systematic reviews, randomised controlled trials, cohort studies and case-control studies. Forward and backward citation chaining was undertaken on relevant systematic reviews and included studies. Studies were screened, coded and assessed for risk of bias by a single reviewer, with a second checking a proportion. The evidence map results were compared to survey results. Thirty-nine people responded to the survey, half of which were clinicians. Of 9796 records identified, 37 reports of 28 studies were included in the evidence map. Many included studies were at some risk of bias; for observational studies, this was predominantly due to lack of controlling for confounders. Most studies (71%) assessed surgical interventions alone. Reporting on other intervention types was limited. Regarding outcome measures most important to survey respondents, 24 studies reported on cure/improvement in obstetric fistula and 20 on cure/improvement in urinary incontinence. Reporting on quality of life, faecal incontinence and sexual function was limited. There is currently little robust evidence to guide patients and practitioners on the most effective treatment option for obstetric fistula. Further research is required to address evidence gaps identified.

Project description:IntroductionThe amount of scientific data on liver surgery is exploding. There is a critical unmet need to develop tools that will facilitate navigating the literature and offer easy, fast and accurate access to data with a high level of evidence. Evidence maps (EM) combining living systematic reviews (SR) and user-friendly synthesis with graphs and figures were developed for this purpose in other medical fields and showed promising results but remain yet unavailable in liver surgery. The present study protocol aims to generate an EM in liver surgery, gathering randomised clinical trials (RCT) and SR.Methods and analysisA systematic search will be conducted in the Cochrane Central Register of Controlled Trials, Web of Science, Embase and Medline to identify all RCT and SR concerning liver surgery. RCT and SR will be classified in research topics. Selected endpoints will be extracted and meta-analysed. Results will be freely available for patients, clinicians and researchers via a web-based evidence map platform. EM and meta-analyses (MA) will be updated at regular intervals.Ethics and disseminationIncluding publicly available data, this type of study design did not require ethical committee approval. EM displays the required properties to facilitate literature search and to get a rapid overview of the current evidence, an unavailable tool in liver surgery, to date. Generating such an aid may considerably help patients, clinicians and researchers in many aspects: accessing accurate data, helping in decision-making and identifying gaps in the field. On completion of the project, results will be published, freely available via www.evidencemap.surgery and permanently updated.Prospero registration numberCRD42023489201 (https://www.crd.york.ac.uk/prospero/).
