National inventory of Global Change relevant research in Norway; Nasjonal kartlegging av global change-relevant forskning

Energy Technology Data Exchange (ETDEWEB)

NONE

2001-05-01

The Norwegian Global Change Committee has made an inventory of global change research (GCR) projects funded by the Research Council of Norway (RCN) in 2001. In lack of a rigid definition, GCR was defined as research that can be considered relevant to the science agenda of the four major international global change programmes DIVERSITAS, IGBP, IHDP and WCRP. Relevance was judged based on the objectives stated for each of the international programmes and their core projects. It was not attempted to check whether the projects had any kind of link to the programmes they were considered relevant for. The grants provided by the RCN in 2001 to GCR as defined above amounts to about 77 mill. NOK. Based on a recent survey on climate change research it is reasonable to estimate that the RCN finances between 30 and 40 % of all GCR in Norway. Accordingly, the total value of Norwegian research relevant to the four international global change programmes in 2001 can be estimated to 192 - 254 mill. NOK.

Relevance as process: judgements in the context of scholarly research

Directory of Open Access Journals (Sweden)

Theresa D. Anderson

2005-01-01

Full Text Available Introduction. This paper discusses how exploring the research process in-depth and over time contributes to a fuller understanding of interactions with various representations of information. Method. A longitudinal ethnographic study explored decisions made by two informants involved in scholarly research. Relevance assessment and information seeking were observed as part of informants' own ongoing research projects. Fieldwork used methods of discovery that allowed informants to shape the exploration of the practices surrounding the evolving understandings of their topics. Analysis. Inductive analysis was carried out on the qualitative data collected over a two-year period of judgements observed on a document-by-document basis. The paper introduces broad categories that point to the variability and richness of the ways that informants used representations of information resources to make relevance judgements. Results. Relevance judgements appear to be drivers of the search and research processes informants moved through during the observations. Focusing on research goals rather than on retrieval tasks brings us to a fuller understanding of the relationship between ultimate research goals and the articulation of those goals in interactions with information systems. Conclusion. Relevance assessment is a process that unfolds in the doing of a search, the making of judgements and the using of texts and representations of information.

Barriers to Research and Evidence (Editorial

Full Text Available I often find attending conferences or workshops a source of reflection or inspiration for editorials, and today I attended an event that proved to be no exception. The HEALER network is a UK grouping of professionals interested in health library research. It brings together those working in health information at an academic, practitioner or strategic capacity as well as those working in higher education, research and the NHS. (http://www.libraryservices.nhs.uk/healer/minutes.htmlThere were a number of interesting presentations, but one (and the subsequent interactive discussions left me with some worrying thoughts. Hannah Spring (2013 presented some of the findings from her PhD that found when health librarians were asked about their barriers to research they reported that they didn't know what research questions to ask! Alternatively if they had research questions they didn't think to engage with the literature or believed that there was no evidence to answer them! If we really don't have any research questions, and we really don't think to look at the literature or there really is no evidence, this is worrying indeed for the future of EBLIP. It's also a situation I don't recognize from being involved in the EBLIP journal and was left wondering whether it was the health librarians perceptions of “research” and “evidence” that was the issue; questions which are being examined in the LIRG Scan which was described in another presentation. The scan is a review of the evidence on: What practitioners understand by research; what kind of research is relevant to LIS practitioners? How do they use research and what are the barriers and facilitators to using research in practice?

Reach and Relevance of Prison Research

Directory of Open Access Journals (Sweden)

Hilde Tubex

2015-04-01

Full Text Available In this contribution I reflect on the changes in the penal landscape and how they impact on prison research. I do this from my experiences as a prison researcher in a variety of roles, in both Europe and Australia. The growing dominance of managerialism has impacted on both corrective services and universities, in ways that have changed the relationship between current prison practices and academically oriented research. Therefore, academics have to question how their contemporary prison research can bridge the emerging gap: how they can not only produce research that adheres to the roots of criminology and provides a base for a rational penal policy, but also how they can develop strategies to get recognition of and funding for this broader contextual work which, although it might not produce results that are immediately identifiable, can be of relevance in indirect ways and in the longer term.

.The unsuitability of the RCT has also been raised regarding generating evidence for EBLIP (e.g. Banks, 2008; however, “best evidence” doesn’t need to be an RCT. The definition of EBLIP provided by Booth (2006 mentions best quality evidence (generated from research, among other elements, but makes no mention of particular research designs. In addition, both Eldredge (2004 and Crumley and Koufogiannakis (2002 have argued for the consideration of a wide type of study designs as evidence within EBLIP, a viewpoint with which I have long agreed. After all, it is much more important to choose a design that is suitable to answer the question at hand and provide good quality evidence, rather than trying to use a "good quality" design at the expense of finding relevant evidence. Bearing that in mind, I'm racking my brains to think of how I can use webometrics and techniques from history to investigate my practice. At the same time, I urge you to think widely about research evidence and try exploring some different methodologies and see what evidence they can reveal.

Pathways to Advancing Aging Policy-Relevant Research in Academic Settings.

Science.gov (United States)

Kietzman, Kathryn G; Troy, Lisa M; Green, Carmen R; Wallace, Steven P

2016-01-01

Policy-level changes have a significant influence on the health and well-being of aging populations. Yet there is often a gap between scientific knowledge and policy action. Although previous research has identified barriers and facilitators to effective knowledge translation, little attention has been given to the role of academic institutions in knowledge generation. This exploratory focus group study examines barriers and pathways to developing and maintaining an aging policy-relevant research agenda in academic settings, and additional challenges associated with minority group membership in this pursuit. Participants were personally committed to conducting policy-relevant research despite institutional barriers such as fewer funding opportunities and less value attributed to their research, particularly in the context of tenure and promotion. Although many viewed their research as an opportunity to make a difference, especially for underserved older adult populations, a number of minority group participants expressed that their policy research interests were marginalized. Participants offer individual and institutional-level strategies for addressing barriers, including collaborating with community members and colleagues and engaging mentors within and outside of their academic institutions. Reframing the valuation of policy research through the diversification of funding and publishing opportunities can better support scholars engaged in aging policy-relevant research.

Qualitative systematic reviews: their importance for our understanding of research relevant to pain.

Science.gov (United States)

Seers, Kate

2015-02-01

This article outlines what a qualitative systematic review is and explores what it can contribute to our understanding of pain. Many of us use evidence of effectiveness for various interventions when working with people in pain. A good systematic review can be invaluable in bringing together research evidence to help inform our practice and help us understand what works. In addition to evidence of effectiveness, understanding how people with pain experience both their pain and their care can help us when we are working with them to provide care that meets their needs. A rigorous qualitative systematic review can also uncover new understandings, often helping illuminate 'why' and can help build theory. Such a review can answer the question 'What is it like to have chronic pain?' This article presents the different stages of meta-ethnography, which is the most common methodology used for qualitative systematic reviews. It presents evidence from four meta-ethnographies relevant to pain to illustrate the types of findings that can emerge from this approach. It shows how new understandings may emerge and gives an example of chronic musculoskeletal pain being experienced as 'an adversarial struggle' across many aspects of the person's life. This article concludes that evidence from qualitative systematic reviews has its place alongside or integrated with evidence from more quantitative approaches.

Evidence, Engagement, and Technology: Themes of and the State of Primary Care Practice-based Network Research.

Science.gov (United States)

Nease, Donald E

2016-01-01

Practice-based research supported by practice-based research network (PBRN) infrastructure has historically provided an important method for challenging guidelines and evidence arising from secondary and tertiary care settings. This sample of current practice-based research in this issue of the JABFM provides an opportunity to ask whether practice-based research continues to address questions relevant to primary care practices and clinicians and whether a PBRN infrastructure is instrumental to maintaining the relevance and feasibility of practice-based research. Based on this issue's articles, the current state of practice-based research seems to be good, at face value addressing relevant issues for primary care practices. Less clear is the degree to which PBRN infrastructures and relationships informed the questions asked and facilitated the implementation of the studies presented. Practice-based research-related articles that routinely report about how study questions arose-from practices and their clinicians, staff and communities, or elsewhere-could help directly answer questions of relevance. In addition, reporting how practices are recruited to practice-based research studies could inform the degree to which ongoing relationships central to PBRNs facilitate the recruitment and conduct of practice-based research. © Copyright 2016 by the American Board of Family Medicine.

Regional IS Knowledge Networks: Elaborating the Theme of Relevance of IS Research

Directory of Open Access Journals (Sweden)

Mikael Söderström

2003-01-01

Full Text Available The purpose of this paper is to elaborate on the theme of the relevance of IS research. Based on recent experiments and experiences in the borderland between research and practice and politics we suggest some additions to the discussion of the IS research relevance in Fitzgerald (2001. One addition concerns relevance to whom, where we suggest considering a regional relevance through cultivation of regional IS knowledge networks. Such networks comprise regional knowledge production in collaboration between researchers and practitioners, and results are made public and tested in other organizations in addition to the research sites. This is closely related to the view of knowledge and research put forward by American pragmatism. A second addition is to complement Fitzgerald's suggestion to expose researchers to practice with the suggestion to expose practitioners to research. It is just as difficult to learn the 'true nature' of research from reading the executive summary in MIS Quarterly as it is to learn the 'true nature' of practice from a couple of interviews with practitioners. A regional IS knowledge network is an excellent opportunity for such double exposure.

Structural stigma: Research evidence and implications for psychological science.

Science.gov (United States)

Hatzenbuehler, Mark L

2016-11-01

Psychological research has provided essential insights into how stigma operates to disadvantage those who are targeted by it. At the same time, stigma research has been criticized for being too focused on the perceptions of stigmatized individuals and on microlevel interactions, rather than attending to structural forms of stigma. This article describes the relatively new field of research on structural stigma, which is defined as societal-level conditions, cultural norms, and institutional policies that constrain the opportunities, resources, and well-being of the stigmatized. I review emerging evidence that structural stigma related to mental illness and sexual orientation (a) exerts direct and synergistic effects on stigma processes that have long been the focus of psychological inquiry (e.g., concealment, rejection sensitivity), (b) serves as a contextual moderator of the efficacy of psychological interventions, and (c) contributes to numerous adverse health outcomes for members of stigmatized groups-ranging from dysregulated physiological stress responses to premature mortality-indicating that structural stigma represents an underrecognized mechanism producing health inequalities. Each of these pieces of evidence suggests that structural stigma is relevant to psychology and therefore deserves the attention of psychological scientists interested in understanding and ultimately reducing the negative effects of stigma.

Value Relevance of Investment Properties: Evidence from the Brazilian Capital Market

Directory of Open Access Journals (Sweden)

Ketlyn Alves Gonçalves

2017-04-01

Full Text Available This study investigates the relevance to the capital market of the assets recognized as investment properties of companies listed on the BM&F BOVESPA, in the period from 2011 to 2014. The research conducted was based on the Ohlson model (1995 and panel analysis was carried out using linear regression with POLS and Fixed and Random Effects estimators. Two hypothesis were made: (i that Earning and Equity generate accounting information relevant to investors; and (2 that Earning, Equity and Investment Property generate accounting information relevant to investors, assuming that investment properties have incremental effect on the relevance of this information relative only to earning and to equity. Both hypotheses were rejected, so it is concluded that Investment Property assets are not of value relevance in the determination of share price and do not influence the decision making of users of accounting information. The study adds to the limited literature on the value relevance of Investment Property, permitting a better understanding of the impact of accounting disclosures used by companies on their market value.

Using mixed methods to identify and answer clinically relevant research questions.

Science.gov (United States)

Shneerson, Catherine L; Gale, Nicola K

2015-06-01

The need for mixed methods research in answering health care questions is becoming increasingly recognized because of the complexity of factors that affect health outcomes. In this article, we argue for the value of using a qualitatively driven mixed method approach for identifying and answering clinically relevant research questions. This argument is illustrated by findings from a study on the self-management practices of cancer survivors and the exploration of one particular clinically relevant finding about higher uptake of self-management in cancer survivors who had received chemotherapy treatment compared with those who have not. A cross-sectional study generated findings that formed the basis for the qualitative study, by informing the purposive sampling strategy and generating new qualitative research questions. Using a quantitative research component to supplement a qualitative study can enhance the generalizability and clinical relevance of the findings and produce detailed, contextualized, and rich answers to research questions that would be unachievable through quantitative or qualitative methods alone. © The Author(s) 2015.

Neurobiological Foundations of Acupuncture: The Relevance and Future Prospect Based on Neuroimaging Evidence

Directory of Open Access Journals (Sweden)

Lijun Bai

2013-01-01

Full Text Available Acupuncture is currently gaining popularity as an important modality of alternative and complementary medicine in the western world. Modern neuroimaging techniques such as functional magnetic resonance imaging, positron emission tomography, and magnetoencephalography open a window into the neurobiological foundations of acupuncture. In this review, we have summarized evidence derived from neuroimaging studies and tried to elucidate both neurophysiological correlates and key experimental factors involving acupuncture. Converging evidence focusing on acute effects of acupuncture has revealed significant modulatory activities at widespread cerebrocerebellar brain regions. Given the delayed effect of acupuncture, block-designed analysis may produce bias, and acupuncture shared a common feature that identified voxels that coded the temporal dimension for which multiple levels of their dynamic activities in concert cause the processing of acupuncture. Expectation in acupuncture treatment has a physiological effect on the brain network, which may be heterogeneous from acupuncture mechanism. “Deqi” response, bearing clinical relevance and association with distinct nerve fibers, has the specific neurophysiology foundation reflected by neural responses to acupuncture stimuli. The type of sham treatment chosen is dependent on the research question asked and the type of acupuncture treatment to be tested. Due to the complexities of the therapeutic mechanisms of acupuncture, using multiple controls is an optimal choice.

Promoting physical therapists’ of research evidence to inform clinical practice: part 1 - theoretical foundation, evidence, and description of the PEAK program

Science.gov (United States)

2014-01-01

Background There is a need for theoretically grounded and evidence-based interventions that enhance the use of research evidence in physical therapist practice. This paper and its companion paper introduce the Physical therapist-driven Education for Actionable Knowledge translation (PEAK) program, an educational program designed to promote physical therapists’ integration of research evidence into clinical decision-making. The pedagogical foundations for the PEAK educational program include Albert Bandura’s social cognitive theory and Malcolm Knowles’s adult learning theory. Additionally, two complementary frameworks of knowledge translation, the Promoting Action on Research Implementation in Health Services (PARiHS) and Knowledge to Action (KTA) Cycle, were used to inform the organizational elements of the program. Finally, the program design was influenced by evidence from previous attempts to facilitate the use of research in practice at the individual and organizational levels. Discussion The 6-month PEAK program consisted of four consecutive and interdependent components. First, leadership support was secured and electronic resources were acquired and distributed to participants. Next, a two-day training workshop consisting of didactic and small group activities was conducted that addressed the five steps of evidence based practice. For five months following the workshop, participants worked in small groups to review and synthesize literature around a group-selected area of common clinical interest. Each group contributed to the generation of a “Best Practices List” - a list of locally generated, evidence-based, actionable behaviors relevant to the groups’ clinical practice. Ultimately, participants agreed to implement the Best Practices List in their clinical practice. Summary This, first of two companion papers, describes the underlying pedagogical theories, knowledge translation frameworks, and research evidence used to derive the PEAK program �

Biomechanics of the thorax - research evidence and clinical expertise.

Science.gov (United States)

Lee, Diane Gail

2015-07-01

Understanding the biomechanics of the thorax is critical for understanding its role in multiple conditions since the thorax is part of many integrated systems including the musculoskeletal, respiratory, cardiac, digestive and urogynecological. The thorax is also an integrated system within itself and an element of the whole body/person. Therefore, understanding the biomechanics of the thorax is fundamental to all forms of treatment for multiple conditions. The interpretation of movement examination findings depends on one's view of optimal biomechanics and the influential factors. This article will provide a synopsis of the current state of research evidence as well as observations from clinical experience pertaining to the biomechanics of the thorax in order to help clinicians organise this knowledge and facilitate evidence-based and informed management of the, often complex, patient with or without thoracic pain and impairment. The integrated systems model (ISM) will be introduced as a way to determine when the noted biomechanical findings are relevant to a patient's clinical presentation.

Information and communication technology (ICT) tools are known to facilitate communication and processing of information and sharing of knowledge by electronic means. In Nigeria, the lack of adequate capacity on the use of ICT by health sector policymakers constitutes a major impediment to the uptake of research evidence into the policymaking process. The objective of this study was to improve the knowledge and capacity of policymakers to access and utilize policy relevant evidence. A modified "before and after" intervention study design was used in which outcomes were measured on the target participants both before the intervention is implemented and after. A 4-point likert scale according to the degree of adequacy; 1 = grossly inadequate, 4 = very adequate was employed. This study was conducted in Ebonyi State, south-eastern Nigeria and the participants were career health policy makers. A two-day intensive ICT training workshop was organized for policymakers who had 52 participants in attendance. Topics covered included: (i). intersectoral partnership/collaboration; (ii). Engaging ICT in evidence-informed policy making; use of ICT for evidence synthesis; (iv) capacity development on the use of computer, internet and other ICT. The pre-workshop mean of knowledge and capacity for use of ICT ranged from 2.19-3.05, while the post-workshop mean ranged from 2.67-3.67 on 4-point scale. The percentage increase in mean of knowledge and capacity at the end of the workshop ranged from 8.3%-39.1%. Findings of this study suggest that policymakers' ICT competence relevant to evidence-informed policymaking can be enhanced through training workshop.

Evidence-based librarianship: searching for the needed EBL evidence.

Science.gov (United States)

Eldredge, J D

2000-01-01

This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL).

Improving the International Agency for Research on Cancer's consideration of mechanistic evidence

International Nuclear Information System (INIS)

Goodman, Julie; Lynch, Heather

2017-01-01

Background: The International Agency for Research on Cancer (IARC) recently developed a framework for evaluating mechanistic evidence that includes a list of 10 key characteristics of carcinogens. This framework is useful for identifying and organizing large bodies of literature on carcinogenic mechanisms, but it lacks sufficient guidance for conducting evaluations that fully integrate mechanistic evidence into hazard assessments. Objectives: We summarize the framework, and suggest approaches to strengthen the evaluation of mechanistic evidence using this framework. Discussion: While the framework is useful for organizing mechanistic evidence, its lack of guidance for implementation limits its utility for understanding human carcinogenic potential. Specifically, it does not include explicit guidance for evaluating the biological significance of mechanistic endpoints, inter- and intra-individual variability, or study quality and relevance. It also does not explicitly address how mechanistic evidence should be integrated with other realms of evidence. Because mechanistic evidence is critical to understanding human cancer hazards, we recommend that IARC develop transparent and systematic guidelines for the use of this framework so that mechanistic evidence will be evaluated and integrated in a robust manner, and concurrently with other realms of evidence, to reach a final human cancer hazard conclusion. Conclusions: IARC does not currently provide a standardized approach to evaluating mechanistic evidence. Incorporating the recommendations discussed here will make IARC analyses of mechanistic evidence more transparent, and lead to assessments of cancer hazards that reflect the weight of the scientific evidence and allow for scientifically defensible decision-making. - Highlights: • IARC has a revised framework for evaluating literature on carcinogenic mechanisms. • The framework is based on 10 key characteristics of carcinogens. • IARC should develop transparent

Limited research exists on researchers' knowledge transfer and exchange (KTE) in the eastern Mediterranean region (EMR). This multi-country study explores researchers' views and experiences regarding the role of health systems and policy research evidence in health policymaking in the EMR, including the factors that influence health policymaking, barriers and facilitators to the use of evidence, and the factors that increase researchers' engagement in KTE. Researchers who published health systems and policy relevant research in 12 countries in the EMR (Bahrain, Egypt, Iran, Jordan, Lebanon, Libya, Morocco, Oman, Palestine, Sudan, Syria, and Yemen) were surveyed. Descriptive analysis and Linear Mixed Regression Models were performed for quantitative sections and the simple thematic analysis approach was used for open-ended questions. A total of 238 researchers were asked to complete the survey (response rate 56%). Researchers indicated transferring results to other researchers (67.2%) and policymakers in the government (40.5%). Less than one-quarter stated that they produced policy briefs (14.5%), disseminated messages that specified possible actions (24.4%), interacted with policymakers and stakeholders in priority-setting (16%), and involved them in their research (19.8%). Insufficient policy dialogue opportunities and collaboration between researchers and policymakers and stakeholders (67.9%), practical constraints to implementation (66%), non-receptive policy environment (61.3%), and politically sensitive findings (57.7%) hindered the use of evidence. Factors that increase researchers' engagement in KTE activities in the region were associated with involving policymakers and stakeholders at various stages such as priority-setting exercises and provision of technical assistance. Researchers in the EMR recognize the importance of using health systems evidence in health policymaking. Potential strategies to improve the use of research evidence emphasize two

Level of evidence is the most widely used metric for the quality of a publication, but instances exist in which a Level I study is neither feasible nor desirable. The goal of this study was to evaluate the level of evidence gap in current orthopedic research, which the authors defined as the disparity between the level of evidence that would be required to optimally answer the primary research question and the level of evidence that was actually used. Five orthopedic surgeons (K.D.B., J.B., J.A., S.D.M., W.N.S.) evaluated blinded articles from the first 6 months of 2010 in the Journal of Bone and Joint Surgery (American Volume) (JBJS-Am), classifying the study type and design and extracting a primary research question from each article. Each evaluator then defined the study type and method, along with the level of evidence that would ideally be used to address the primary research question. The level of evidence gap was then calculated by subtracting the actual level of evidence of the manuscript from the level of evidence of the idealized study. Of the 64 JBJS-Am manuscripts eligible for analysis, the average level of evidence was between Level II and III (mean, 2.73). The average level of evidence gap was 1.06 compared with the JBJS-Am-designated level of evidence and 1.28 compared with the evaluators' assessment. Because not all questions require Level I studies, level of evidence alone may not be the best metric for the quality of orthopedic surgery literature. Instead, the authors' concept of a level of evidence gap may be a better tool for assessing the state of orthopedic research publications. Copyright 2012, SLACK Incorporated.

To derive evidence-based and stakeholder-informed research priorities for implementation in African settings, the international research consortium Collaboration for Evidence-Based Healthcare and Public Health in Africa (CEBHA+) developed and applied a pragmatic approach. First, an online survey and face-to-face consultation between CEBHA+ partners and policy-makers generated priority research areas. Second, evidence maps for these priority research areas identified gaps and related priority research questions. Finally, study protocols were developed for inclusion within a grant proposal. Policy and practice representatives were involved throughout the process. Tuberculosis, diabetes, hypertension and road traffic injuries were selected as priority research areas. Evidence maps covered screening and models of care for diabetes and hypertension, population-level prevention of diabetes and hypertension and their risk factors, and prevention and management of road traffic injuries. Analysis of these maps yielded three priority research questions on hypertension and diabetes and one on road traffic injuries. The four resulting study protocols employ a broad range of primary and secondary research methods; a fifth promotes an integrated methodological approach across all research activities. The CEBHA+ approach, in particular evidence mapping, helped to formulate research questions and study protocols that would be owned by African partners, fill gaps in the evidence base, address policy and practice needs and be feasible given the existing research infrastructure and expertise. The consortium believes that the continuous involvement of decision-makers throughout the research process is an important means of ensuring that studies are relevant to the African context and that findings are rapidly implemented.

Full Text Available To cope with cancer and its treatment-related side effects and toxicities, people are increasingly using complementary and alternative medicine (CAM. Consequently, integrative oncology, which combines conventional therapies and evidence-based CAM practices, is an emerging discipline in cancer care. The use of yoga as a CAM is proving to be beneficial and increasingly gaining popularity. An electronic database search (PubMed, through December 15, 2016, revealed 138 relevant clinical trials (single-armed, nonrandomized, and randomized controlled trials on the use of yoga in cancer patients. A total of 10,660 cancer patients from 20 countries were recruited in these studies. Regardless of some methodological deficiencies, most of the studies reported that yoga improved the physical and psychological symptoms, quality of life, and markers of immunity of the patients, providing a strong support for yoga's integration into conventional cancer care. This review article presents the published clinical research on the prevalence of yoga's use in cancer patients so that oncologists, researchers, and the patients are aware of the evidence supporting the use of this relatively safe modality in cancer care.

Agenda Setting and Evidence in Maternal Health: Connecting Research and Policy in Timor-Leste.

Wild, Kayli; Kelly, Paul; Barclay, Lesley; Martins, Nelson

2015-01-01

The evidence-based policy (EBP) movement has received significant attention in the scientific literature; however, there is still very little empirical research to provide insight into how policy decisions are made and how evidence is used. The lack of research on this topic in low- and middle-income countries is of particular note. We examine the maternity waiting home policy in Timor-Leste to understand the role of context, policy characteristics, individual actors, and how evidence is used to influence the policy agenda. The research tracked the maternity waiting home policy from 2005 to 2009 and is based on in-depth interviews with 31 senior policy-makers, department managers, non-government organization representatives, and United Nations advisors. It is also informed by direct observation, attendance at meetings and workshops, and analysis of policy documents. The findings from this ethnographic case study demonstrate that although the post-conflict context opened up space for new policy ideas senior Ministry of Health officials rather than donors had the most power in setting the policy agenda. Maternity waiting homes were appealing because they were a visible, non-controversial, and logical solution to the problem of accessing maternal health services. Evidence was used in a variety of ways, from supporting pre-determined agendas to informing new policy directions. In the pursuit of EBP, we conclude that the power of research to inform policy lies in its timeliness and relevance, and is facilitated by the connection between researchers and policy-makers.

Kelder, Johannes C; Rutten, Frans H; Hoes, Arno W

2009-02-01

With the emergence of novel diagnostic tests, e.g. point-of-care tests, clinically relevant empirical evidence is needed to assess whether such a test should be used in daily practice. With the example of the value of B-type natriuretic peptides (BNP) in the diagnostic assessment of suspected heart failure, we will discuss the major methodological issues crucial in diagnostic research; most notably the choice of the study population and the data analysis with a multivariable approach. BNP have been studied extensively in the emergency care setting, and also several studies in the primary care are available. The usefulness of this test when applied in combination with other readily available tests is still not adequately addressed in the relevant patient domain, i.e. those who are clinically suspected of heart failure by their GP. Future diagnostic research in primary care should be targeted much more at answering the clinically relevant question 'Is it useful to add this (new) test to the other tests I usually perform, including history taking and physical examination, in patients I suspect of having a certain disease'.

Biomechanics of the thorax – research evidence and clinical expertise

Science.gov (United States)

Lee, Diane Gail

2015-01-01

Understanding the biomechanics of the thorax is critical for understanding its role in multiple conditions since the thorax is part of many integrated systems including the musculoskeletal, respiratory, cardiac, digestive and urogynecological. The thorax is also an integrated system within itself and an element of the whole body/person. Therefore, understanding the biomechanics of the thorax is fundamental to all forms of treatment for multiple conditions. The interpretation of movement examination findings depends on one's view of optimal biomechanics and the influential factors. This article will provide a synopsis of the current state of research evidence as well as observations from clinical experience pertaining to the biomechanics of the thorax in order to help clinicians organise this knowledge and facilitate evidence-based and informed management of the, often complex, patient with or without thoracic pain and impairment. The integrated systems model (ISM) will be introduced as a way to determine when the noted biomechanical findings are relevant to a patient's clinical presentation. PMID:26309383

The Common Body of Knowledge: A Framework to Promote Relevant Information Security Research

2007-03-01

Full Text Available This study proposes using an established common body of knowledge (CBK as one means of organizing information security literature.  Consistent with calls for more relevant information systems (IS research, this industry-developed framework can motivate future research towards topics that are important to the security practitioner.  In this review, forty-eight articles from ten IS journals from 1995 to 2004 are selected and cross-referenced to the ten domains of the information security CBK.  Further, we distinguish articles as empirical research, frameworks, or tutorials.  Generally, this study identified a need for additional empirical research in every CBK domain including topics related to legal aspects of information security.  Specifically, this study identified a need for additional IS security research relating to applications development, physical security, operations security, and business continuity.  The CBK framework is inherently practitioner oriented and using it will promote relevancy by steering IS research towards topics important to practitioners.  This is important considering the frequent calls by prominent information systems scholars for more relevant research.  Few research frameworks have emerged from the literature that specifically classify the diversity of security threats and range of problems that businesses today face.  With the recent surge of interest in security, the need for a comprehensive framework that also promotes relevant research can be of great value.

Patenting of university and non-university public research organisations in Germany: evidence from patent applications for medical research results.

Directory of Open Access Journals (Sweden)

Peter Tinnemann

Full Text Available BACKGROUND: Patents are one of the most important forms of intellectual property. They grant a time-limited exclusivity on the use of an invention allowing the recuperation of research costs. The use of patents is fiercely debated for medical innovation and especially controversial for publicly funded research, where the patent holder is an institution accountable to public interest. Despite this controversy, for the situation in Germany almost no empirical information exists. The purpose of this study is to examine the amount, types and trends of patent applications for health products submitted by German public research organisations. METHODS/PRINCIPAL FINDINGS: We conducted a systematic search for patent documents using the publicly accessible database search interface of the German Patent and Trademark Office. We defined keywords and search criteria and developed search patterns for the database request. We retrieved documents with application date between 1988 and 2006 and processed the collected data stepwise to compile the most relevant documents in patent families for further analysis. We developed a rationale and present individual steps of a systematic method to request and process patent data from a publicly accessible database. We retrieved and processed 10194 patent documents. Out of these, we identified 1772 relevant patent families, applied for by 193 different universities and non-university public research organisations. 827 (47% of these patent families contained granted patents. The number of patent applications submitted by universities and university-affiliated institutions more than tripled since the introduction of legal reforms in 2002, constituting almost half of all patent applications and accounting for most of the post-reform increase. Patenting of most non-university public research organisations remained stable. CONCLUSIONS: We search, process and analyse patent applications from publicly accessible databases

Developing independent investigators for clinical research relevant for Africa

LENUS (Irish Health Repository)

Manabe, Yukari C

2011-12-29

Abstract Sustainable research capacity building requires training individuals at multiple levels within a supportive institutional infrastructure to develop a critical mass of independent researchers. At many African medical institutions, a PhD is important for academic promotion and is, therefore, an important focal area for capacity building programs. We examine the training at the Infectious Diseases Institute (IDI) as a model for in-country training based on systems capacity building and attention to the academic environment. PhD training in Africa should provide a strong research foundation for individuals to perform independent, original research and to mentor others. Training the next generation of researchers within excellent indigenous academic centers of excellence with strong institutional infrastructure will empower trainees to ask regionally relevant research questions that will benefit Africans.

Prioritizing comparative effectiveness research may contribute to obtaining answers that clinicians perceive they need and may minimize research that could be considered wasteful. Our objective was to identify evidence gaps and set priorities for new systematic reviews and randomized controlled trials for managing diabetic retinopathy (DR), including diabetic macular edema (DME). Cross-sectional study. Diabetic Retinopathy Clinical Research Network (DRCR.net) investigators. We provided recommendations from the American Academy of Ophthalmology's 2012 Preferred Practice Patterns for Diabetic Retinopathy as 91 answerable clinical research questions about intervention effectiveness to 410 DRCR.net investigators to rate each question's importance from 0 (not important) to 10 (very important) using a 2-round Delphi survey and to suggest additional questions. We considered questions as high priority if at least 75% of respondents to both rounds assigned an importance rating of 5 or more in round 2. We also extracted outcome measures relevant to DR and asked respondents to identify those that must be measured in all studies. We mapped Cochrane reviews published up to March 2016 to high-priority clinical research questions. Ranking of importance of each clinical question. Thirty-two individuals completed rounds 1 and 2 and suggested 15 questions. Among the final list of 106 clinical research questions, 22 questions met our definition of high priority: 9 of 22 concerned the effectiveness of anti-VEGF therapy, and 13 of 22 focused on how often patients should be followed up (re-examination) and treatment effectiveness in patients with specific characteristics (e.g., DME). Outcomes that 75% or more of respondents marked as "must be measured in all studies" included visual acuity and visual loss, death of participants, and intraocular pressure. Only 1 prioritized question was associated with conclusive evidence from a Cochrane systematic review. A limited response rate among

Lohr, Kathleen N

2004-02-01

To summarize an extensive review of systems for grading the quality of research articles and rating the strength of bodies of evidence, and to highlight for health professionals and decision-makers concerned with quality measurement and improvement the available "best practices" tools by which these steps can be accomplished. Drawing on an extensive review of checklists, questionnaires, and other tools in the field of evidence-based practice, this paper discusses clinical, management, and policy rationales for rating strength of evidence in a quality improvement context, and documents best practices methods for these tasks. After review of 121 systems for grading the quality of articles, 19 systems, mostly specific, met a priori scientific standards for grading systematic reviews, randomized controlled trials, observational studies, and diagnostic tests; eight systems (of 40 reviewed) met similar standards for rating the overall strength of evidence. All can be used as is or adapted for particular types of evidence reports or systematic reviews. Formally grading study quality and rating overall strength of evidence, using sound instruments and procedures, can produce reasonable levels of confidence about the science base for parts of quality improvement programs. With such information, health care professionals and administrators concerned with quality improvement can understand better the level of science (versus only clinical consensus or opinion) that supports practice guidelines, review criteria, and assessments that feed into quality assurance and improvement programs. New systems are appearing and research is needed to confirm the conceptual and practical underpinnings of these grading and rating systems, but the need for those developing systematic reviews, practice guidelines, and quality or audit criteria to understand and undertake these steps is becoming increasingly clear.

Structural Stigma and Health Inequalities: Research Evidence and Implications for Psychological Science

Science.gov (United States)

Hatzenbuehler, Mark L.

2016-01-01

Psychological research has provided essential insights into how stigma operates to disadvantage those who are targeted by it. At the same time, stigma research has been criticized for being too focused on the perceptions of stigmatized individuals and on micro-level interactions, rather than attending to structural forms of stigma. This article describes the relatively new field of research on structural stigma, which is defined as societal-level conditions, cultural norms, and institutional policies that constrain the opportunities, resources, and wellbeing of the stigmatized. I review emerging evidence that structural stigma related to mental illness and sexual orientation (1) exerts direct and synergistic effects on stigma processes that have long been the focus of psychological inquiry (e.g., concealment, rejection sensitivity); (2) serves as a contextual moderator of the efficacy of psychological interventions; and (3) contributes to numerous adverse health outcomes for members of stigmatized groups—ranging from dysregulated physiological stress responses to premature mortality—indicating that structural stigma represents an under-recognized mechanism producing health inequalities. Each of these pieces of evidence suggests that structural stigma is relevant to psychology and therefore deserves the attention of psychological scientists interested in understanding and ultimately reducing the negative effects of stigma.

Research utilisation is essential in developing evidence-based practices; although many students may be generally able to adopt such skills, there are reports of barriers related to critical appraisal skills. To explore how students perceive the relevance of research to future clinical practice and patients, and to what extent they read research (including reading pattern). Additionally, the objective was to explore whether a three-week intensive course in critical appraisal of research could affect these variables. A cross-sectional survey design, with a pre- and post-test. One large university college in Southeastern Norway. 196 multidisciplinary healthcare students at baseline and 147 after three weeks. A purposely-designed 21 item questionnaire was used to quantify students' attitudes towards using research and critical thinking. The questionnaire was based on themes emerging from prior focus group interviews with 10 nursing and social educator students as well as from the existing literature. At baseline, 6.1% and 7.1% of respondents perceived the research to be of little or very little importance for their future work and patients, respectively. Furthermore, 83.2% reported that they seldom or very seldom read scientific papers. At baseline, 40 different patterns of reading a scientific paper were identified. Additionally, 7.1% of respondents reported to read the introduction, methods and conclusion in combination. Significantly improved scores were found after completing the three-week course related to a) relevance of research for future work (pskills in critical appraisal (pstudents' practical critical appraisal skills improved their view of the relevance of research for patients, future work as well as their own critical appraisal skills.

The source of research may influence one's interpretation of it in either negative or positive ways, however, there are no robust experiments to determine how source impacts on one's judgment of the research article. We determine the impact of source on respondents' assessment of the quality and relevance of selected research abstracts. Web-based survey design using four healthcare research abstracts previously published and included in Cochrane Reviews. All Council on the Education of Public Health-accredited Schools and Programmes of Public Health in the USA. 899 core faculty members (full, associate and assistant professors) Each of the four abstracts appeared with a high-income source half of the time, and low-income source half of the time. Participants each reviewed the same four abstracts, but were randomly allocated to receive two abstracts with high-income source, and two abstracts with low-income source, allowing for within-abstract comparison of quality and relevance Within-abstract comparison of participants' rating scores on two measures--strength of the evidence, and likelihood of referral to a peer (1-10 rating scale). OR was calculated using a generalised ordered logit model adjusting for sociodemographic covariates. Participants who received high income country source abstracts were equal in all known characteristics to the participants who received the abstracts with low income country sources. For one of the four abstracts (a randomised, controlled trial of a pharmaceutical intervention), likelihood of referral to a peer was greater if the source was a high income country (OR 1.28, 1.02 to 1.62, pincome source in their rating of research abstracts.

Full Text Available Abstract Background The World Health Organization (WHO, like many other organisations around the world, has recognised the need to use more rigorous processes to ensure that health care recommendations are informed by the best available research evidence. This is the sixth of a series of 16 reviews that have been prepared as background for advice from the WHO Advisory Committee on Health Research to WHO on how to achieve this. Objectives We reviewed the literature on determining which outcomes are important for the development of guidelines. Methods We searched five databases of methodological studies for existing systematic reviews and relevant methodological research. We did not conduct a complete systematic review ourselves. Our conclusions are based on the available evidence, consideration of what WHO and other organisations are doing and logical arguments. Key questions and answers We did not find a systematic review that addresses any of the following key questions and we found limited relevant research evidence. What methods should WHO use to identify important outcomes? • Methods of outcome identification should be transparent and explicit. • The consultation process should start with identification of all relevant outcomes associated with an intervention. • Those affected, including consumers, should be involved in the selection of outcomes. • A question driven approach (what is important? is preferable to a data driven approach (what data are at hand? to identify important outcomes. What type of outcomes should WHO consider and how should cultural diversity be taken account of in the selection of outcomes? • Desirable (benefits, less burden and savings and undesirable effects should be considered in all guidelines. • Undesirable effects include harms (including the possibility of unanticipated adverse effects, greater burden (e.g. having to go to the doctor and costs (including opportunity costs. • Important outcomes (e

Research philosophy in pharmacy practice: necessity and relevance.

Winit-Watjana, Win

2016-12-01

Pharmacy practice has gradually evolved with the paradigm shifted towards patient-focused practice or medicines optimisation. The advancement of pharmacy-related research has contributed to this progression, but the philosophy of research remained unexplored. This review was thus aimed to outline the succinct concept of research philosophy and its application in pharmacy practice research. Research philosophy has been introduced to offer an alternative way to think about problem-driven research that is normally conducted. To clarify the research philosophy, four research paradigms, i.e. positivism (or empiricism), postpositivism (or realism), interpretivism (or constructivism) and pragmatism, are investigated according to philosophical realms, i.e. ontology, epistemology, axiology and logic of inquiry. With the application of research philosophy, some examples of quantitative and qualitative research were elaborated along with the conventional research approach. Understanding research philosophy is crucial for pharmacy researchers and pharmacists, as it underpins the choice of methodology and data collection. The review provides the overview of research philosophy and its application in pharmacy practice research. Further discussion on this vital issue is warranted to help generate quality evidence for pharmacy practice. © 2016 Royal Pharmaceutical Society.

An evidence perspective on topical relevance types and its implications for exploratory and task-based retrieval

Directory of Open Access Journals (Sweden)

Xiaoli Huang

2006-01-01

Full Text Available Introduction. The concept of relevance lies at the heart of intellectual access and information retrieval, indeed of reasoning and communication in general; in turn, topical relevance lies at the heart of relevance. The common view of topical relevance is limited to topic matching, resulting in information retrieval systems' failure to detect more complex topical connections which are needed to respond to diversified user situations and tasks. Method. Based on the role a piece of information plays in the overall structure of an argument, we have identified four topical relevance types: Direct, Indirect (circumstantial, Context, and Comparison. In the process of creating a speech retrieval test collection, graduate history students made 27,000 topical relevance assessments between Holocaust survivor interview segments and real user topics, using the four relevance types, each on a scale of 0 to 4. They recorded justifications for their assessments and kept detailed Topic Notes. Analysis. We analysed these relevance assessments using a grounded theory approach to arrive at a finer classification of topical relevance types. Results. For example, indirect relevance(a piece of information is connected to the topic indirectly through inference, circumstantial evidence was refined to Generic Indirect Relevance, Backward Inference (abduction, Forward Inference (deduction, and Inference from Cases (induction, with each subtype being further illustrated and explicated by examples. Conclusion. Each of these refined types of topical relevance plays a special role in reasoning, making a conclusive argument, or performing a task. Incorporating them into information retrieval systems allows users more flexibility and a better focus on their tasks. They can also be used in teaching reasoning skills.

Modeling Evidence-Based Application: Using Team-Based Learning to Increase Higher Order Thinking in Nursing Research

Directory of Open Access Journals (Sweden)

Bridget Moore

2015-06-01

Full Text Available Nursing practice is comprised of knowledge, theory, and research [1]. Because of its impact on the profession, the appraisal of research evidence is critically important. Future nursing professionals must be introduced to the purpose and utility of nursing research, as early exposure provides an opportunity to embed evidence-based practice (EBP into clinical experiences. The AACN requires baccalaureate education to include an understanding of the research process to integrate reliable evidence to inform practice and enhance clinical judgments [1]. Although the importance of these knowledge competencies are evident to healthcare administrators and nursing leaders within the field, undergraduate students at the institution under study sometimes have difficulty understanding the relevance of nursing research to the baccalaureate prepared nurse, and struggle to grasp advanced concepts of qualitative and quantitative research design and methodologies. As undergraduate nursing students generally have not demonstrated an understanding of the relationship between theoretical concepts found within the undergraduate nursing curriculum and the practical application of these concepts in the clinical setting, the research team decided to adopt an effective pedagogical active learning strategy, team-based learning (TBL. Team-based learning shifts the traditional course design to focus on higher thinking skills to integrate desired knowledge [2]. The purpose of this paper is to discuss the impact of course design with the integration of TBL in an undergraduate nursing research course on increasing higher order thinking.

Partnering Healthy@Work (pH@W), an inaugural recipient of funding through Australia's Partnership for Better Health Grants scheme, was a 5-year partnership between the Menzies Institute for Medical Research, University of Tasmania and the Tasmanian State Service (TSS). The partnerships purpose was to evaluate a comprehensive workplace health promotion programme (Healthy@Work) targeting 30 000 public sector employees; generating new knowledge and influencing workplace health promotion policy and decision-making. This mixed methods study evaluates the partnership between policy-makers and academics and identifies strategies that enabled pH@W to deliver key project outcomes. A pH@W document review was conducted, two partnership assessment tools completed and semi-structured interviews conducted with key policy-makers and academics. Analysis of the partnership assessment tools and interviews found that pH@W had reached a strong level of collaboration. Policy-relevant knowledge was generated about the health of TSS employees and their engagement with workplace health promotion. Knowledge exchange of a conceptual and instrumental nature occurred and was facilitated by the shared grant application, clear governance structures, joint planning, regular information exchange between researchers and policy-makers and research student placements in the TSS. Flexibility and acknowledgement of different priorities and perspectives of partner organizations were identified as critical factors for enabling effective partnership working and research relevance. Academic-policy-maker partnerships can be a powerful mechanism for improving policy relevance of research, but need to incorporate strategies that facilitate regular input from researchers and policy-makers in order to achieve this. © The Author 2016.

To describe the process of implementing evidence-based practice in a clinical nursing setting. Evidence-based practice has become a major issue in nursing, it is insufficiently integrated into daily practice and its implementation is complex. Participatory action research. The main participants were nurses working in a lung unit of a rural hospital. A multi-method process of data collection was used during the observing, reflecting, planning and acting phases. Data were continuously gathered during a 24-month period from 2010 to 2012, and analysed using an interpretive constant comparative approach. Patients were consulted to incorporate their perspective. A best-practice mode of working was prevalent on the ward. The main barriers to the implementation of evidence-based practice were that nurses had little knowledge of evidence-based practice and a rather negative attitude towards it, and that their English reading proficiency was poor. The main facilitators were that nurses wanted to deliver high-quality care and were enthusiastic and open to innovation. Implementation strategies included a tailored interactive outreach training and the development and implementation of an evidence-based discharge protocol. The academic model of evidence-based practice was adapted. Nurses worked according to the evidence-based practice discharge protocol but barely recorded their activities. Nurses favourably evaluated the participatory action research process. Action research provides an opportunity to empower nurses and to tailor evidence-based practice to the practice context. Applying and implementing evidence-based practice is difficult for front-line nurses with limited evidence-based practice competencies. Adaptation of the academic model of evidence-based practice to a more pragmatic approach seems necessary to introduce evidence-based practice into clinical practice. The use of scientific evidence can be facilitated by using pre-appraised evidence. For clinical practice

LANGUAGE EXPERIENCE SHAPES PROCESSING OF PITCH RELEVANT INFORMATION IN THE HUMAN BRAINSTEM AND AUDITORY CORTEX: ELECTROPHYSIOLOGICAL EVIDENCE.

Science.gov (United States)

Krishnan, Ananthanarayan; Gandour, Jackson T

2014-12-01

Pitch is a robust perceptual attribute that plays an important role in speech, language, and music. As such, it provides an analytic window to evaluate how neural activity relevant to pitch undergo transformation from early sensory to later cognitive stages of processing in a well coordinated hierarchical network that is subject to experience-dependent plasticity. We review recent evidence of language experience-dependent effects in pitch processing based on comparisons of native vs. nonnative speakers of a tonal language from electrophysiological recordings in the auditory brainstem and auditory cortex. We present evidence that shows enhanced representation of linguistically-relevant pitch dimensions or features at both the brainstem and cortical levels with a stimulus-dependent preferential activation of the right hemisphere in native speakers of a tone language. We argue that neural representation of pitch-relevant information in the brainstem and early sensory level processing in the auditory cortex is shaped by the perceptual salience of domain-specific features. While both stages of processing are shaped by language experience, neural representations are transformed and fundamentally different at each biological level of abstraction. The representation of pitch relevant information in the brainstem is more fine-grained spectrotemporally as it reflects sustained neural phase-locking to pitch relevant periodicities contained in the stimulus. In contrast, the cortical pitch relevant neural activity reflects primarily a series of transient temporal neural events synchronized to certain temporal attributes of the pitch contour. We argue that experience-dependent enhancement of pitch representation for Chinese listeners most likely reflects an interaction between higher-level cognitive processes and early sensory-level processing to improve representations of behaviorally-relevant features that contribute optimally to perception. It is our view that long

Contributions of qualitative research to evidence-based practice in nursing

Full Text Available AIM: This article aims to identify the contributions of qualitative research to evidence-based practice in nursing. BACKGROUND: Qualitative research dates back to the 1920s and 1930s, when anthropologists and sociologists used qualitative research methods to study human phenomena in naturalistic settings and from a holistic viewpoint. Afterwards, other subject matters, including nursing, adopted qualitative methods to answer their research questions. The restructuring of health care over the past decade has brought about increased accountability in nursing research. One method for increasing this accountability is evidence-based practice. METHOD: The method used was a search in the Cumulative Index to Nursing and Allied Health Literature database from 1999-present. The search resulted in 61 citations for evidence-based practice in nursing research; however, only 5 citations focused on evidence-based practice and qualitative research. FINDINGS: The authors' findings revealed six contributions of qualitative research to evidence-based practice: generation of hypotheses; development and validation of instruments; provision of context for evaluation; development of nursing interventions; development of new research questions; and application of Qualitative Outcome Analysis. CONCLUSION: Qualitative research makes important contributions to the quality of evidence-based practice.

Science youth action research: Promoting critical science literacy through relevance and agency

Science.gov (United States)

Coleman, Elizabeth R.

This three-article dissertation presents complementary perspectives on Science Youth Action Research (Sci-YAR), a K-12 curriculum designed to emphasize relevance and agency to promote youth's science learning. In Sci-YAR, youth conduct action research projects to better understand science-related issues in their lives, schools, or communities, while they simultaneously document, analyze, and reflect upon their own practices as researchers. The first article defines Sci-YAR and argues for its potential to enhance youth's participation as citizens in a democratic society. The second article details findings from a case study of youth engaged in Sci-YAR, describing how the curriculum enabled and constrained youth's identity work in service of critical science agency. The third article provides guidance to science teachers in implementing student-driven curriculum and instruction by emphasizing Sci-YAR's key features as a way to promote student agency and relevance in school science.

Communication among scientists, decision makers and society: Developing policy-relevant global climate change research

International Nuclear Information System (INIS)

Bernabo, J.C.

1995-01-01

Defining the research most relevant to policy is not simply a technical task that can be answered by scientists. Decision makers need and value information differently than curiosity-driven scientists. In order to link science more effectively to policy, the two communities must gain a greater mutual understanding. Decision makers must define their needs so that scientists can determine how, and by when, research can address these needs. This vital dialogue between communities typically has been more ad hoc than systematic. The complexity and urgency of the global climate change issue necessitate ongoing communication between scientists and decision makers on the information needed for policy development and what research can provide The results of relevant science policy dialogues are discussed herein. Effective communication between researchers and decision makers is a crucial ingredient for successfully addressing society's pressing environmental concerns. The increase in policy makers' demands for research that is relevant to solving societal issues highlights the communication gap between the technical and policy communities. The gap, largely caused by lack of mutual understanding, results in flawed and inadequate communication that hinders decision making and confuses the public. This paper examines the cause of this communication gap and describes the significance of recent efforts to develop more fruitful science-policy dialogues on the issue of global climate change. First, the post-Cold War shift in government priorities for research funding is described; then the underlying relationship between science and policy is explored to identify key sources of ongoing mis-communication. The paper then explains the importance of defining policy-relevant science questions that research can address. Finally, three projects are described involving the elicitation of decision makers' information needs in The United States, The Netherlands, and internationally

Making sense of evidence in management decisions: the role of research-based knowledge on innovation adoption and implementation in healthcare. study protocol.

Science.gov (United States)

Kyratsis, Yiannis; Ahmad, Raheelah; Holmes, Alison

2012-03-21

We know that patient care can be improved by implementing evidence-based innovations and applying research findings linked to good practice. Successfully implementing innovations in complex organisations, such as the UK's National Health Service (NHS), is often challenging as multiple contextual dynamics mediate the process. Research studies have explored the challenges of introducing innovations into healthcare settings and have contributed to a better understanding of why potentially useful innovations are not always implemented in practice, even if backed by strong evidence. Mediating factors include health policy and health system influences, organisational factors, and individual and professional attitudes, including decision makers' perceptions of innovation evidence. There has been limited research on how different forms of evidence are accessed and utilised by organisational decision makers during innovation adoption. We also know little about how diverse healthcare professionals (clinicians, administrators) make sense of evidence and how this collective sensemaking mediates the uptake of innovations. The study will involve nine comparative case study sites of acute care organisations grouped into three regional clusters across England. Each of the purposefully selected sites represents a variety of trust types and organisational contexts. We will use qualitative methods, in-depth interviews, observation of key meetings, and systematic analysis of relevant secondary data to understand the rationale and challenges involved in sourcing and utilising innovation evidence in the empirical setting of infection prevention and control. We will use theories of innovation adoption and sensemaking in organisations to interpret the data. The research will provide lessons for the uptake and continuous use of innovations in the English and international health systems. Unlike most innovation studies, which involve single-level analysis, our study will explore the

Functional dyspepsia: Are psychosocial factors of relevance?

Institute of Scientific and Technical Information of China (English)

Sandra Barry; Timothy G Dinan

2006-01-01

The pathogenesis of Functional Dyspepsia (FD) remains unclear, appears diverse and is thus inadequately understood. Akin to other functional gastrointestinal disorders, research has demonstrated an association between this common diagnosis and psychosocial factors and psychiatric morbidity. Conceptualising the relevance of these factors within the syndrome of FD requires application of the biopsychosocial model of disease.Using this paradigm, dysregulation of the reciprocal communication between the brain and the gut is central to symptom generation, interpretation and exacerbation.Appreciation and understanding of the neurobiological correlates of various psychological states is also relevant.The view that psychosocial factors exert their influence in FD predominantly through motivation of health care seeking also persists. This appears too one-dimensional an assertion in light of the evidence available supporting a more intrinsic aetiological link. Evolving understanding of pathogenic mechanisms and the heterogeneous nature of the syndrome will facilitate effective management.Co-morbid psychiatric illness warrants treatment with conventional therapies. Acknowledging the relevance of psychosocial variables in FD, the degree of which is subject to variation, has implications for assessment and management. Available evidence suggests psychological therapies may benefit FD patients particularly those with chronic symptoms. The rationale for use of psychotropic medications in FD is apparent but the evidence base to support the use of antidepressant pharmacotherapy is to date limited.

Panisset Ulysses

2012-07-01

Full Text Available Abstract A major obstacle to the progress of the Millennium Development Goals has been the inability of health systems in many low- and middle-income countries to effectively implement evidence-informed interventions. This article discusses the relationships between implementation research and knowledge translation and identifies the role of implementation research in the design and execution of evidence-informed policy. After a discussion of the benefits and synergies needed to translate implementation research into action, the article discusses how implementation research can be used along the entire continuum of the use of evidence to inform policy. It provides specific examples of the use of implementation research in national level programmes by looking at the scale up of zinc for the treatment of childhood diarrhoea in Bangladesh and the scaling up of malaria treatment in Burkina Faso. A number of tested strategies to support the transfer of implementation research results into policy-making are provided to help meet the standards that are increasingly expected from evidence-informed policy-making practices.

Research examining the utilization of evidence-based practice (EBP) specifically among rehabilitation clinicians is limited. The objective of this study was to examine how various rehabilitative clinicians including physical therapists, occupational therapists, rehabilitation counselors, and physiatrists are gaining access to literature and whether they are able to implement the available research into practice. A total of 21 total clinicians were interviewed via telephone. Using NVivo, a qualitative analysis of the responses was performed. There were similarities found with respect to the information-seeking behaviors and translation of research across the different clinician types. Lack of time was reported to be a barrier for both access to literature and implementation of research across all clinician types. The majority of clinicians who reported having difficulty with utilizing the published literature indicated that the literature was not applicable to their practice, the research was not specific enough to be put into practice, or the research found was too outdated to be relevant. In addition, having a supportive work environment aided in the search and utilization of research through providing resources central to assisting clinicians in gaining access to health information. Our study identified several barriers that affect EBP for rehabilitation clinicians. The findings suggest the need for researchers to ensure that their work is applicable and specific to clinical practice for implementation to occur.

The aim of this paper was to give an overview of relevant streams of research that can form a basis for research on user-oriented innovation in the food sector. We define user-oriented innovation as a process towards the development of a new product or service in which an integrated analysis...... and understanding of the users' wants, needs and preference formation play a key role. We distinguish three relevant streams of research that may provide a basis for research on user-oriented innovation in the food sector: research on the formation of user preferences, research on innovation management......, and research on interactive innovation. We show that the relevance of these three streams of research for the food sector depends on which type of innovation we are dealing with, and we propose a distinction of three types of food innovations depending on which actors in the food chain are involved...

Goering, Paula; Boydell, Katherine M; Pignatiello, Antonio

2008-03-01

It is time to move beyond education about qualitative research theory and methods to using them to understand and improve psychiatric practice. There is a good fit between this agenda and current thinking about research use that broadens definitions of evidence beyond the results of experiments. This paper describes a qualitative program evaluation to illustrate what kind of useful knowledge is generated and how it can be created through a clinician-researcher partnership. The linkage and exchange model of effective knowledge translation described involves interaction between clinicians and researchers throughout the research process and results in mutual learning through the planning, disseminating, and application of existing or new qualitative research in decision making.

IEK-3 is one of nine sub-institutes within the Institute of Energy and Climate Research at Forschungszentrum Juelich GmbH. IEK-3 aims to conduct research of social, ecological and economic relevance and thus generate groundbreaking results on an international level. This quality of work is achieved through basic research in close coordination with technical development work in relevant scientific and technical fields of expertise. Special significance is attached here to international cooperations with partners from research and industry. By implementing research results in innovative products, procedures and processes in cooperation with industry, IEK-3 hopes to help bridge the gap between science and technology. Cooperation with universities, universities of applied sciences, training departments and training centers is designed to promote opportunities for further education and training. With a staff of approximately 100, IEK-3 concentrates on the basic topics of electrochemistry and process engineering for fuel cells. In an integrated approach, the four key areas worked on in the institute - direct methanol fuel cells, high-temperature polymer electrolyte fuel cells, solid oxide fuel cells and fuel processing systems - are accompanied by systems analysis and theoretical investigations, basic modeling and simulations, and by experimental and theoretical systems evaluations. The information generated in these areas is used to design and verify functional systems. In addition, particular attention is given to the development, configuration and application of special measuring techniques for the structural analysis of membrane electrode assemblies, for flow simulation and visualization, and for the characterization of stacks. The solid oxide fuel cell (SOFC) stack pictured comprises 36 cells, each with an active cell area of 360 cm{sup 2}. The nominal power at a mean cell voltage of 800 mV is approximately 5.5 kW. The stack is operated on natural gas, which is

Roadmap for a participatory research-practice partnership to implement evidence.

Harrison, Margaret B; Graham, Ian D

2012-12-01

Our research team has undertaken implementation of evidence in the form of practice guideline recommendations for populations in hospital, community, and long-term care settings with diverse provider and patient populations (people with chronic wounds, e.g., pressure and leg ulcers, heart failure, stroke, diabetes, palliative care, cancer, and maternity care). Translating evidence into clinical practice at the point of care is a complex and often overwhelming challenge for the health system as well as for individual practitioners. To ensure that best available evidence is integrated into practice, "local evidence" needs to be generated and this process accomplishes a number of things: it focuses all involved on the "same page," identifies important facilitating factors as well as barriers, provides empirical support for planning, and in itself is a key aspect of implementation. In doing this work, we developed a roadmap, the Queen's University Research Roadmap for Knowledge Implementation (QuRKI) that outlines three major phases of linked research and implementation activity: (1) issue identification/clarification; (2) solution building; and (3) implementation, evaluation, and nurturing the change. In this paper, we describe our practical experience as researchers working at point-of-care and how research can be used to facilitate the implementation of evidence. An exemplar is used to illustrate the fluid interplay of research and implementation activities and present the range of supporting research. QuRKI serves as a guide for researchers in the formation of a strategic alliance with the practice community for undertaking evidence-informed reorganization of care. Using this collaborative approach, researchers play an integral role in focusing on, and using evidence during all discussions. We welcome further evaluation of its usefulness in the field. © 2012 Sigma Theta Tau International.

Full Text Available Abstract Background There is limited information about how transgender, gender diverse, and Two-Spirit (trans people have been represented and studied by researchers. The objectives of this study are to (1 map and describe trans research in the social sciences, sciences, humanities, health, education, and business, (2 identify evidence gaps and opportunities for more responsible research with trans people, (3 assess the use of text mining for study identification, and (4 increase access to trans research for key stakeholders through the creation of a web-based evidence map. Methods Study design was informed by community consultations and pilot searches. Eligibility criteria were established to include all original research of any design, including trans people or their health information, and published in English in peer-reviewed journals. A complex electronic search strategy based on relevant concepts in 15 databases was developed to obtain a broad range of results linked to transgender, gender diverse, and Two-Spirit individuals and communities. Searches conducted in early 2015 resulted in 25,242 references after removal of duplicates. Based on the number of references, resources, and an objective to capture upwards of 90% of the existing literature, this study is a good candidate for text mining using Latent Dirichlet Allocation to improve efficiency of the screening process. The following information will be collected for evidence mapping: study topic, study design, methods and data sources, recruitment strategies, sample size, sample demographics, researcher name and affiliation, country where research was conducted, funding source, and year of publication. Discussion The proposed research incorporates an extensive search strategy, text mining, and evidence map; it therefore has the potential to build on knowledge in several fields. Review results will increase awareness of existing trans research, identify evidence gaps, and inform

Kong, Fanchang; Zhang, Yan; Tian, Yuan; Fan, Cuiying; Zhou, Zongkui

2015-03-01

This study examines the electrophysiological correlates of beauty evaluation when participants performed the self-reference task. About 13 (7 men, 6 women) undergraduates participated in the experiment using event-related potentials. Results showed that the response to self-relevant information was faster compared to other-relevant information and no significant differences for self-relevant relative to mother-relevant information were observed. Both physical and interior beauty words for self-relevant information showed an enhanced late positive component as compared to other-relevant information. Physical beauty for self-relevant information yielded a larger late positive component in contrast to mother-relevant information but not for interior beauty. This study indicates that beauty is specific to the person who judges it though an individual and one's mother may hold similar views of interior beauty.

A mandated reduction in the nicotine content of cigarettes may improve public health by reducing the prevalence of smoking. Animal self-administration research is an important complement to clinical research on nicotine reduction. It can fill research gaps that may be difficult to address with clinical research, guide clinical researchers about variables that are likely to be important in their own research, and provide policy makers with converging evidence between clinical and preclinical studies about the potential impact of a nicotine reduction policy. Convergence between clinical and preclinical research is important, given the ease with which clinical trial participants can access nonstudy tobacco products in the current marketplace. Herein, we review contributions of preclinical animal research, with a focus on rodent self-administration, to the science of nicotine reduction. Throughout this review, we highlight areas where clinical and preclinical research converge and areas where the two differ. Preclinical research has provided data on many important topics such as the threshold for nicotine reinforcement, the likelihood of compensation, moderators of the impact of nicotine reduction, the impact of environmental stimuli on nicotine reduction, the impact of nonnicotine cigarette smoke constituents on nicotine reduction, and the impact of nicotine reduction on vulnerable populations. Special attention is paid to current research gaps including the dramatic rise in alternative tobacco products, including electronic nicotine delivery systems (ie, e-cigarettes). The evidence reviewed here will be critical for policy makers as well as clinical researchers interested in nicotine reduction. This review will provide policy makers and clinical researchers interested in nicotine reduction with an overview of the preclinical animal research conducted on nicotine reduction and the regulatory implications of that research. The review also highlights the utility of

Full Text Available Abstract Background The Contextualized Health Research Synthesis Program (CHRSP, developed in 2007 by the Newfoundland and Labrador Centre for Applied Health Research, produces contextualized knowledge syntheses for health-system decision makers. The program provides timely, relevant, and easy-to-understand scientific evidence; optimizes evidence uptake; and, most importantly, attunes research questions and evidence to the specific context in which knowledge users must apply the findings. Methods As an integrated knowledge translation (KT method, CHRSP: Involves intensive partnerships with senior healthcare decision makers who propose priority research topics and participate on research teams; Considers local context both in framing the research question and in reporting the findings; Makes economical use of resources by utilizing a limited number of staff; Uses a combination of external and local experts; and Works quickly by synthesizing high-level systematic review evidence rather than primary studies. Although it was developed in the Canadian province of Newfoundland and Labrador, the CHRSP methodology is adaptable to a variety of settings with distinctive features, such as those in rural, remote, and small-town locations. Results CHRSP has published 25 syntheses on priority topics chosen by the provincial healthcare system, including: Clinical and cost-effectiveness: telehealth, rural renal dialysis, point-of-care testing; Community-based health services: helping seniors age in place, supporting seniors with dementia, residential treatment centers for at-risk youth; Healthcare organization/service delivery: reducing acute-care length of stay, promoting flu vaccination among health workers, safe patient handling, age-friendly acute care; and Health promotion: diabetes prevention, promoting healthy dietary habits.

Behavioral Recommendations in Health Research News as Cues to Action: Self-Relevancy and Self-Efficacy Processes.

Science.gov (United States)

Chang, Chingching

2016-08-01

This study argues that behavioral recommendations in health news function as cues to action. A proposed self-oriented model seeks to explore the impacts of behavioral recommendations in health research news as cues to action through their influences on self-relevancy and self-efficacy. A content analysis (Study 1) first establishes that health research news commonly features behavioral recommendations. A message experiment (Study 2) then explores the utility of behavioral recommendations as cues to action by demonstrating a self-relevancy effect: Health research news with, as opposed to without, behavioral recommendations increases the self-relevancy of advocated health behaviors, which then improve people's attitudes toward and intentions to adopt those behaviors. A second message experiment (Study 3) tests whether varying presentations of behavioral recommendations alter their effectiveness as cues to action and thus people's behavioral intentions through a dual effect process. In addition to the previously demonstrated self-relevancy effect, this experiment shows that concrete, as opposed to abstract, behavioral recommendations trigger a self-efficacy effect, increasing perceived self-efficacy and further improving behavioral intentions.

Full Text Available Abstract Background We know that patient care can be improved by implementing evidence-based innovations and applying research findings linked to good practice. Successfully implementing innovations in complex organisations, such as the UK's National Health Service (NHS, is often challenging as multiple contextual dynamics mediate the process. Research studies have explored the challenges of introducing innovations into healthcare settings and have contributed to a better understanding of why potentially useful innovations are not always implemented in practice, even if backed by strong evidence. Mediating factors include health policy and health system influences, organisational factors, and individual and professional attitudes, including decision makers' perceptions of innovation evidence. There has been limited research on how different forms of evidence are accessed and utilised by organisational decision makers during innovation adoption. We also know little about how diverse healthcare professionals (clinicians, administrators make sense of evidence and how this collective sensemaking mediates the uptake of innovations. Methods The study will involve nine comparative case study sites of acute care organisations grouped into three regional clusters across England. Each of the purposefully selected sites represents a variety of trust types and organisational contexts. We will use qualitative methods, in-depth interviews, observation of key meetings, and systematic analysis of relevant secondary data to understand the rationale and challenges involved in sourcing and utilising innovation evidence in the empirical setting of infection prevention and control. We will use theories of innovation adoption and sensemaking in organisations to interpret the data. The research will provide lessons for the uptake and continuous use of innovations in the English and international health systems. Discussion Unlike most innovation studies, which involve

Critical appraisal of clinical evidence promises to help prevent, detect, and address flaws related to study importance, ethics, validity, applicability, and reporting. These research issues are of growing concern. The purpose of this scoping review is to survey the current literature on evidence appraisal to develop a conceptual framework and an informatics research agenda. We conducted an iterative literature search of Medline for discussion or research on the critical appraisal of clinical evidence. After title and abstract review, 121 articles were included in the analysis. We performed qualitative thematic analysis to describe the evidence appraisal architecture and its issues and opportunities. From this analysis, we derived a conceptual framework and an informatics research agenda. We identified 68 themes in 10 categories. This analysis revealed that the practice of evidence appraisal is quite common but is rarely subjected to documentation, organization, validation, integration, or uptake. This is related to underdeveloped tools, scant incentives, and insufficient acquisition of appraisal data and transformation of the data into usable knowledge. The gaps in acquiring appraisal data, transforming the data into actionable information and knowledge, and ensuring its dissemination and adoption can be addressed with proven informatics approaches. Evidence appraisal faces several challenges, but implementing an informatics research agenda would likely help realize the potential of evidence appraisal for improving the rigor and value of clinical evidence. © The Author 2017.

Green Sally E

2012-08-01

Full Text Available Abstract The Neurotrauma Evidence Translation (NET program was funded in 2009 to increase the uptake of research evidence in the clinical care of patients who have sustained traumatic brain injury. This paper reports the rationale and plan for this five-year knowledge translation research program. The overarching aims of the program are threefold: to improve outcomes for people with traumatic brain injury; to create a network of neurotrauma clinicians and researchers with expertise in knowledge translation and evidence-based practice; and to contribute knowledge to the field of knowledge translation research. The program comprises a series of interlinked projects spanning varying clinical environments and disciplines relevant to neurotrauma, anchored within four themes representing core knowledge translation activities: reviewing research evidence; understanding practice; developing and testing interventions for practice change; and building capacity for knowledge translation in neurotrauma. The program uses a range of different methods and study designs, including: an evidence fellowship program; conduct of and training in systematic reviews; mixed method study designs to describe and understand factors that influence current practices (e.g., semi-structured interviews and surveys; theory-based methods to develop targeted interventions aiming to change practice; a cluster randomised trial to test the effectiveness of a targeted theory-informed intervention; stakeholder involvement activities; and knowledge translation events such as consensus conferences.

Evidence-based assessment (EBA) is a critically important aspect of delivering high-quality, school-based mental health care for youth. However, research in this area is limited and additional applied research on how best to support the implementation of EBA in school mental health (SMH) is needed. Accordingly, this manuscript seeks to facilitate the advancement of research on EBA in SMH by reviewing relevant literature on EBA implementation in schools and providing recommendations for key research priorities. Given the limited number of published studies available, findings from child and adolescent mental health and implementation science research are also included to inform a robust and comprehensive research agenda on this topic. Based on this literature review, five priorities for research on EBA in SMH are outlined: (1) effective identification of assessment targets, (2) appropriate selection of assessment measures, (3) investigation of organizational readiness for EBA, (4) study of implementation support for EBA, and (5) promotion of EBA data integration and use. Each priority area includes recommended directions for future research. A comprehensive and robust research agenda is warranted to build the science and practice of implementing EBA in SMH. Specific directions for this agenda are offered.

Throughout the world, there is increasing awareness and acknowledgement of the value of research evidence in the development of effective health policy and in quality health care practice and administration. Among the major challenges associated with the lack of uptake of research evidence into policy and practice in Nigeria is the capacity constraints of policymakers to use research evidence in policy making. To assess the capacity of maternal and child health policy makers to acquire, access, adapt and apply available research evidence. This cross-sectional quantitative survey was conducted at a national maternal, newborn and child health (MNCH) stakeholders' engagement event. An evidence to policy self-assessment questionnaire was used to assess the capacity of forty MNCH policy makers to acquire, assess, adapt and apply research evidence for policy making. Low mean ratings were observed ranging from 2.68-3.53 on a scale of 5 for knowledge about initiating/conducting research and capacity to assess authenticity, validity, reliability, relevance and applicability of research evidence and for organizational capacity for promoting and using of research for policy making. There is need to institute policy makers' capacity development programmes to improve evidence-informed policymaking.

The objective of this study is to identify and appraise qualitative research evidence on the experience of making life-support decisions in critical care. In six databases and supplementary sources, we sought original research published from January 1990 through June 2008 reporting qualitative empirical studies of the experience of life-support decision making in critical care settings. Fifty-three journal articles and monographs were included. Of these, 25 reported prospective studies and 28 reported retrospective studies. We abstracted methodologic characteristics relevant to the basic critical appraisal of qualitative research (prospective data collection, ethics approval, purposive sampling, iterative data collection and analysis, and any method to corroborate findings). Qualitative research traditions represented include grounded theory (n = 15, 28%), ethnography or naturalistic methods (n = 15, 28%), phenomenology (n = 9, 17%), and other or unspecified approaches (n = 14, 26%). All 53 documents describe the research setting; 97% indicate purposive sampling of participants. Studies vary in their capture of multidisciplinary clinician and family perspectives. Thirty-one (58%) report research ethics board review. Only 49% report iterative data collection and analysis, and eight documents (15%) describe an analytically driven stopping point for data collection. Thirty-two documents (60%) indicated a method for corroborating findings. Qualitative evidence often appears outside of clinical journals, with most research from the United States. Prospective, observation-based studies follow life-support decision making directly. These involve a variety of participants and yield important insights into interactions, communication, and dynamics. Retrospective, interview-based studies lack this direct engagement, but focus on the recollections of fewer types of participants (particularly patients and physicians), and typically address specific issues (communication and

Health technology assessment (HTA) agencies increasingly use reviews of qualitative research as evidence for evaluating social, experiential, and ethical aspects of health technologies. We systematically searched three bibliographic databases (MEDLINE, CINAHL, and Social Science Citation Index [SSCI]) using published search filters or "hedges" and our hybrid filter to identify qualitative research studies pertaining to chronic obstructive pulmonary disease and early breast cancer. The search filters were compared in terms of sensitivity, specificity, and precision. Our screening by title and abstract revealed that qualitative research constituted only slightly more than 1% of all published research on each health topic. The performance of the published search filters varied greatly across topics and databases. Compared with existing search filters, our hybrid filter demonstrated a consistently high sensitivity across databases and topics, and minimized the resource-intensive process of sifting through false positives. We identify opportunities for qualitative health researchers to improve the uptake of qualitative research into evidence-informed policy making. © The Author(s) 2016.

Relevant Information and Informed Consent in Research: In Defense of the Subjective Standard of Disclosure.

Dranseika, Vilius; Piasecki, Jan; Waligora, Marcin

2017-02-01

In this article, we seek to contribute to the debate on the requirement of disclosure in the context of informed consent for research. We defend the subjective standard of disclosure and describe ways to implement this standard in research practice. We claim that the researcher should make an effort to find out what kinds of information are likely to be relevant for those consenting to research. This invites researchers to take empirical survey information seriously, attempt to understand the cultural context, talk to patients to be better able to understand what can be potentially different concerns and interests prevalent in the target population. The subjective standard of disclosure should be seen as a moral ideal that perhaps can never be perfectly implemented but still can and should be used as a normative ideal guiding research practice. In the light of these discussions, we call for more empirical research on what considerations are likely to be perceived as relevant by potential research participants recruited from different socio-economic and cultural groups.

Clinical quality indicators are used to monitor the performance of healthcare services and should wherever possible be based on research evidence. Little is known however about the extent to which indicators in common use are based on research. The objective of this study is to measure the extent to which clinical quality indicators used in asthma management in children with outcome measurements can be linked to results in randomised controlled clinical trial (RCT) reports. This work is part of a broader research program to trial methods that improve the efficiency and accuracy of indicator development. National-level indicators for asthma management in children were extracted from the National Quality Measures Clearinghouse database and the National Institute for Health and Care Excellence quality standards by two independent appraisers. Outcome measures were extracted from all published English language RCT reports for asthma management in children below the age of 12 published between 2005 and 2014. The two sets were then linked by manually mapping both to a common set of Unified Medical Language System (UMLS) concepts. The analysis identified 39 indicators and 562 full text RCTs dealing with asthma management in children. About 95% (37/39) of the indicators could be linked to RCT outcome measures. It is possible to identify relevant RCT reports for the majority of indicators used to assess the quality of asthma management in childhood. The methods reported here could be automated to more generally support assessment of candidate indicators against the research evidence.

Policy-makers working at the interface of agri-food and public health often deal with complex and cross-cutting issues that have broad health impacts and socio-economic implications. They have a responsibility to ensure that policy-making based on these issues is accountable and informed by the best available scientific evidence. We conducted a qualitative descriptive study of agri-food public health policy-makers and research and policy analysts in Ontario, Canada, to understand their perspectives on how the policy-making process is currently informed by scientific evidence and how to facilitate this process. Five focus groups of 3-7 participants and five-one-to-one interviews were held in 2012 with participants from federal and provincial government departments and industry organizations in the agri-food public health sector. We conducted a thematic analysis of the focus group and interview transcripts to identify overarching themes. Participants indicated that the following six key principles are necessary to enable and demonstrate evidence-informed policy-making (EIPM) in this sector: (i) establish and clarify the policy objectives and context; (ii) support policy-making with credible scientific evidence from different sources; (iii) integrate scientific evidence with other diverse policy inputs (e.g. economics, local applicability and stakeholder interests); (iv) ensure that scientific evidence is communicated by research and policy stakeholders in relevant and user-friendly formats; (V) create and foster interdisciplinary relationships and networks across research and policy communities; and (VI) enhance organizational capacity and individual skills for EIPM. Ongoing and planned efforts in these areas, a supportive culture, and additional education and training in both research and policy realms are important to facilitate evidence-informed policy-making in this sector. Future research should explore these findings further in other countries and contexts. �

Evidence-informed capacity building for setting health priorities in low- and middle-income countries: A framework and recommendations for further research.

Priority-setting in health is risky and challenging, particularly in resource-constrained settings. It is not simply a narrow technical exercise, and involves the mobilisation of a wide range of capacities among stakeholders - not only the technical capacity to "do" research in economic evaluations. Using the Individuals, Nodes, Networks and Environment (INNE) framework, we identify those stakeholders, whose capacity needs will vary along the evidence-to-policy continuum. Policymakers and healthcare managers require the capacity to commission and use relevant evidence (including evidence of clinical and cost-effectiveness, and of social values); academics need to understand and respond to decision-makers' needs to produce relevant research. The health system at all levels will need institutional capacity building to incentivise routine generation and use of evidence. Knowledge brokers, including priority-setting agencies (such as England's National Institute for Health and Care Excellence, and Health Interventions and Technology Assessment Program, Thailand) and the media can play an important role in facilitating engagement and knowledge transfer between the various actors. Especially at the outset but at every step, it is critical that patients and the public understand that trade-offs are inherent in priority-setting, and careful efforts should be made to engage them, and to hear their views throughout the process. There is thus no single approach to capacity building; rather a spectrum of activities that recognises the roles and skills of all stakeholders. A range of methods, including formal and informal training, networking and engagement, and support through collaboration on projects, should be flexibly employed (and tailored to specific needs of each country) to support institutionalisation of evidence-informed priority-setting. Finally, capacity building should be a two-way process; those who build capacity should also attend to their own capacity

2014-01-01

The purpose of this review was to synthesize and critique experimental and/or quasi-experimental research that has evaluated implementation strategies for translation of research-based evidence into nursing practice. Successfully implementing evidence-based research can improve patient outcomes. Identifying successful implementation strategies is imperative to move research-based evidence into practice. As implementation science gains popularity, it is imperative to understand the strategies that most effectively translate research-based evidence into practice. The review used the CINAHL and MEDLINE (Ovid) databases. Articles were included if they were experimental and/or quasi-experimental research designs, were written in English, and measured nursing compliance to translation of research-based evidence. An independent review was performed to select and critique the included articles. A wide array of interventions were completed, including visual cues, audit and feedback, educational meetings and materials, reminders, outreach, and leadership involvement. Because of the complex multimodal nature of the interventions and the variety of research topics, comparison across interventions was difficult. Many difficulties exist in determining what implementation strategies are most effective for translation of research-based evidence into practice by nurses. With these limited findings, further research is warranted to determine which implementation strategies most successfully translate research-based evidence into practice.

Systematic review of the neurobiological relevance of chemokines to psychiatric disorders

2015-09-01

Full Text Available Psychiatric disorders are highly prevalent and disabling conditions of increasing public health relevance. Much recent research has focused on the role of cytokines in the pathophysiology of psychiatric disorders; however the related family of immune proteins designated chemokines has been relatively neglected. Chemokines were originally identified as having chemotactic function on immune cells, however recent evidence has begun to elucidate novel, brain-specific functions of these proteins of relevance to the mechanisms of psychiatric disorders. A systematic review of both human and animal literature in the PubMed and Google Scholar databases was undertaken. After application of all inclusion and exclusion criteria, 157 references were remained for the review. Some early mechanistic evidence does associate select chemokines with the neurobiological processes, including neurogenesis, modulation of the neuroinflammatory response, regulation of the HPA axis, and modulation of neurotransmitter systems. This early evidence however does not clearly demonstrate any specificity for a certain psychiatric disorder, but is primarily relevant to mechanisms which are shared across disorders. Notable exceptions include CCL11 which has recently been shown to impair hippocampal function in aging - of distinct relevance to Alzheimer’s disease and depression in the elderly, and prenatal exposure to CXCL8 that may disrupt early neurodevelopmental periods predisposing to schizophrenia. Pro-inflammatory chemokines, such as CCL2, CCL7, CCL8, CCL12, CCL13, have been shown to drive chemotaxis of pro-inflammatory cells to the inflamed or injured CNS. Likewise, CX3CL has been implicated in promoting glial cells activation, proinflammatory cytokines secretion, expression of ICAM-1 and recruitment of CD4+ T-cells into the CNS during neuroinflammatory processes. With further translational research, chemokines may present novel diagnostic and/or therapeutic targets in

Full Text Available Abstract Background Research evidence underpins best practice, but is not always used in healthcare. The Promoting Action on Research Implementation in Health Services (PARIHS framework suggests that the nature of evidence, the context in which it is used, and whether those trying to use evidence are helped (or facilitated affect the use of evidence. Urinary incontinence has a major effect on quality of life of older people, has a high prevalence, and is a key priority within European health and social care policy. Improving continence care has the potential to improve the quality of life for older people and reduce the costs associated with providing incontinence aids. Objectives This study aims to advance understanding about the contribution facilitation can make to implementing research findings into practice via: extending current knowledge of facilitation as a process for translating research evidence into practice; evaluating the feasibility, effectiveness, and cost-effectiveness of two different models of facilitation in promoting the uptake of research evidence on continence management; assessing the impact of contextual factors on the processes and outcomes of implementation; and implementing a pro-active knowledge transfer and dissemination strategy to diffuse study findings to a wide policy and practice community. Setting and sample Four European countries, each with six long-term nursing care sites (total 24 sites for people aged 60 years and over with documented urinary incontinence Methods and design Pragmatic randomised controlled trial with three arms (standard dissemination and two different programmes of facilitation, with embedded process and economic evaluation.

Keeping research reactors relevant: A pro-active approach for SLOWPOKE-2

International Nuclear Information System (INIS)

Cosby, L.R.; Bennett, L.G.I.; Nielsen, K.; Weir, R.

2010-01-01

The SLOWPOKE is a small, inherently safe, pool-type research reactor that was engineered and marketed by Atomic Energy of Canada Limited (AECL) in the 1970s and 80s. The original reactor, SLOWPOKE-1, was moved from Chalk River to the University of Toronto in 1970 and was operated until upgraded to the SLOWPOKE-2 reactor in 1973. In all, eight reactors in the two versions were produced and five are still in operation today, three having been decommissioned. All of the remaining reactors are designated as SLOWPOKE-2 reactors. These research reactors are prone to two major issues: aging components and lack of relevance to a younger audience. In order to combat these problems, one SLOWPOKE -2 facility has embraced a strategy that involves modernizing their reactor in order to keep the reactor up to date and relevant. In 2001, this facility replaced its aging analogue reactor control system with a digital control system. The system was successfully commissioned and has provided a renewed platform for student learning and research. The digital control system provides a better interface and allows flexibility in data storage and retrieval that was never possible with the analogue control system. This facility has started work on another upgrade to the digital control and instrumentation system that will be installed in 2010. The upgrade includes new computer hardware, updated software and a web-based simulation and training system that will allow licensed operators, students and researchers to use an online simulation tool for training, education and research. The tool consists of: 1) A dynamic simulation for reactor kinetics (e.g., core flux, power, core temperatures, etc). This tool is useful for operator training and student education; 2) Dynamic mapping of the reactor and pool container gamma and neutron fluxes as well as the vertical neutron beam tube flux. This research planning tool is used for various researchers who wish to do irradiations (e.g., neutron

Fossil Fuel Industry Funding of Climate-Relevant Research at U.S. Universities

Franta, B.; Supran, G.

2017-12-01

Commercial producers of lead, tobacco, petroleum, and other products have funded extensive scholarly research in ways designed to confuse the public about the dangers of those products and thwart regulation [1-3]. For example, strategy documentation of the U.S. oil and gas industry from the late 1990s describes using selective support for scientists as a strategy for creating an atmosphere of debate and uncertainty, with the ultimate goal of delaying and defeating climate policies [4]. In this context, we systematically examine current funding from commercial fossil fuel interests of climate-relevant research - such as energy technology and climate policy research - in U.S. universities. We quantify such funding using charitable giving databases, university websites, and other publicly available records. We find that, especially among the most influential universities, climate-related research programs are frequently dominated by funding from fossil fuel interests. Moreover, these relationships sometimes afford funders privileges including formal control over research directions. This work represents an advance in mapping the presence of commercial fossil fuel interests in academia and may contribute to discussions of appropriate funding systems for climate-relevant research. 1.

It has become essential in policy and decision-making circles to think about the economic benefits (in addition to moral and scientific motivations) humans derive from well-functioning ecosystems. The concept of ecosystem services has been developed to address this link between ecosystems and human welfare. Since policy decisions are often evaluated through cost-benefit assessments, an economic analysis can help make ecosystem service research operational. In this paper we provide some simple economic analyses to discuss key concepts involved in formalizing ecosystem service research. These include the distinction between services and benefits, understanding the importance of marginal ecosystem changes, formalizing the idea of a safe minimum standard for ecosystem service provision, and discussing how to capture the public benefits of ecosystem services. We discuss how the integration of economic concepts and ecosystem services can provide policy and decision makers with a fuller spectrum of information for making conservation-conversion trade-offs. We include the results from a survey of the literature and a questionnaire of researchers regarding how ecosystem service research can be integrated into the policy process. We feel this discussion of economic concepts will be a practical aid for ecosystem service research to become more immediately policy relevant.

From research excellence to brand relevance: A model for higher education reputation building

Directory of Open Access Journals (Sweden)

Nina Overton-de Klerk

2016-05-01

Full Text Available In this article we propose a novel approach to reputation development at higher education institutions. Global reputation development at higher education institutions is largely driven by research excellence, is predominantly measured by research output, and is predominantly reflected in hierarchical university rankings. The ranking becomes equated with brand equity. We argue that the current approach to reputation development in higher education institutions is modernist and linear. This is strangely out-of-kilter with the complexities of a transforming society in flux, the demands of a diversity of stakeholders, and the drive towards transdisciplinarity, laterality, reflexivity and relevance in science. Good research clearly remains an important ingredient of a university's brand value. However, a case can be made for brand relevance, co-created in collaboration with stakeholders, as an alternative and non-linear way of differentiation. This approach is appropriate in light of challenges in strategic science globally as well as trends and shifts in the emerging paradigm of strategic communication. In applying strategic communication principles to current trends and issues in strategic science and the communication thereof, an alternative model for strategic reputation building at higher education institutions is developed.

Converging research needs across framework convention on tobacco control articles: making research relevant to global tobacco control practice and policy.

2013-04-01

Much of the research used to support the ratification of the WHO Framework Convention on Tobacco Control (FCTC) was conducted in high-income countries or in highly controlled environments. Therefore, for the global tobacco control community to make informed decisions that will continue to effectively inform policy implementation, it is critical that the tobacco control community, policy makers, and funders have updated information on the state of the science as it pertains to provisions of the FCTC. Following the National Cancer Institute's process model used in identifying the research needs of the U.S. Food and Drug Administration's relatively new tobacco law, a core team of scientists from the Society for Research on Nicotine and Tobacco identified and commissioned internationally recognized scientific experts on the topics covered within the FCTC. These experts analyzed the relevant sections of the FCTC and identified critical gaps in research that is needed to inform policy and practice requirements of the FCTC. This paper summarizes the process and the common themes from the experts' recommendations about the research and related infrastructural needs. Research priorities in common across Articles include improving surveillance, fostering research communication/collaboration across organizations and across countries, and tracking tobacco industry activities. In addition, expanding research relevant to low- and middle-income countries (LMIC), was also identified as a priority, including identification of what existing research findings are transferable, what new country-specific data are needed, and the infrastructure needed to implement and disseminate research so as to inform policy in LMIC.

The objective of this study was to examine how various rehabilitative clinicians including physical therapists, occupational therapists, rehabilitation counselors, and physiatrists are gaining access to literature and whether they are able to implement the available research into practice.Methods: A total of 21 total clinicians were interviewed via telephone. Using NVivo, a qualitative analysis of the responses was performed.Results: There were similarities found with respect to the information-seeking behaviors and translation of research across the different clinician types. Lack of time was reported to be a barrier for both access to literature and implementation of research across all clinician types. The majority of clinicians who reported having difficulty with utilizing the published literature indicated that the literature was not applicable to their practice, the research was not specific enough to be put into practice, or the research found was too outdated to be relevant. In addition, having a supportive work environment aided in the search and utilization of research through providing resources central to assisting clinicians in gaining access to health information.Conclusion: Our study identified several barriers that affect EBP for rehabilitation clinicians. The findings suggest the need for researchers to ensure that their work is applicable and specific to clinical practice for implementation to occur.

Music therapists have an ethical and professional responsibility to provide the highest quality care possible to their patients. Much of the time, high quality care is guided by evidence-based practice standards that integrate the most current, available research in making decisions. Accordingly, music therapists need research that integrates multiple ways of knowing and forms of evidence. Mixed methods research holds great promise for facilitating such integration. At this time, there have not been any methodological articles published on mixed methods research in music therapy. The purpose of this article is to introduce mixed methods research as an approach to address research questions relevant to music therapy practice. This article describes the core characteristics of mixed methods research, considers paradigmatic issues related to this research approach, articulates major challenges in conducting mixed methods research, illustrates four basic designs, and provides criteria for evaluating the quality of mixed methods articles using examples of mixed methods research from the music therapy literature. Mixed methods research offers unique opportunities for strengthening the evidence base in music therapy. Recommendations are provided to ensure rigorous implementation of this research approach.

The main evidences of epidemiology, diagnostic imaging, pathology, surgery, radiotherapy, chemotherapy and follow-up are reviewed to optimize the routine treatment of rectal cancer according to a multidisciplinary approach. This paper reports on the knowledge shared between different specialists involved in the design and management of the multidisciplinary ESTRO Teaching Course on Rectal Cancer. The scenario of ongoing research is also addressed. In this time of changing treatments, it clearly appears that a common standard for large heterogeneous patient groups have to be substituted by more individualised therapies based on clinical-pathological features and very soon on molecular and genetic markers. Only trained multidisciplinary teams can face this new challenge and tailor the treatments according to the best scientific evidence for each patient

This article addresses the need for policy-relevant research agendas on family care in transaction with formal care and public as well as organisational norms and policies in light of the crisis in caregiving for older adults. We propose a combined institutional and life-course theoretical approach, suggesting seven ways of organising scholarly enquiry to promote understanding of the changing nature of family care in the 21st century, inform policymakers' efforts at supporting family caregivers and improve caregivers' and care recipients' quality of life. These include: (1) moving beyond snapshots of individuals; (2) conducting comparative cross-cultural and crosscohort analyses; (3) documenting social heterogeneity, vulnerability and inequality; (4) capturing individuals' and families' adaptive strategies and cycles of control during the caregiving process; (5) investigating policy innovations and natural experiments; (6) assessing third parties as mediating institutions between regulatory environments and caregiving families; and (7) attending to the subjective meanings of care.

To describe and categorize contextual information relevant to patients' medical care unexpectedly volunteered to research personnel as part of a patient advocate (PA) intervention to facilitate access health care, communication with medical personnel, and self-management of a chronic disease such as asthma. We adapted a patient navigator intervention, to overcome barriers to access and communication for adults with moderate or severe asthma. Informed by focus groups of patients and providers, our PAs facilitated preparation for a visit with an asthma provider, attended the visit, confirmed understanding, and assisted with post-visit activities. During meetings with researchers, either for PA activities or for data collection, participants frequently volunteered personal and medical information relevant for achieving successful self-management that was not routinely shared with medical personnel. For this project, researchers journaled information not captured by the structured questionnaires and protocol. Using a qualitative analysis, we describe (1) researchers' journals of these unique communications; (2) their relevance for accomplishing self-management; (3) PAs' formal activities including teach-back, advocacy, and facilitating appointment making; and (4) observations of patients' interactions with the clinical practices. In 83 journals, patients' social support (83%), health (68%), and deportment (69%) were described. PA assistance with navigating the medical system (59%), teach-back (46%), and observed interactions with patient and medical staff (76%) were also journaled. Implicit were ways patients and practices could overcome barriers to access and communication. These journals describe the importance of seeking contextual and medically relevant information from all patients and, especially, those with significant morbidities, prompting patients for barriers to access to health care, and confirming understanding of medical information.

The Limits to Relevance

Science.gov (United States)

Averill, M.; Briggle, A.

2006-12-01

Science policy and knowledge production lately have taken a pragmatic turn. Funding agencies increasingly are requiring scientists to explain the relevance of their work to society. This stems in part from mounting critiques of the "linear model" of knowledge production in which scientists operating according to their own interests or disciplinary standards are presumed to automatically produce knowledge that is of relevance outside of their narrow communities. Many contend that funded scientific research should be linked more directly to societal goals, which implies a shift in the kind of research that will be funded. While both authors support the concept of useful science, we question the exact meaning of "relevance" and the wisdom of allowing it to control research agendas. We hope to contribute to the conversation by thinking more critically about the meaning and limits of the term "relevance" and the trade-offs implicit in a narrow utilitarian approach. The paper will consider which interests tend to be privileged by an emphasis on relevance and address issues such as whose goals ought to be pursued and why, and who gets to decide. We will consider how relevance, narrowly construed, may actually limit the ultimate utility of scientific research. The paper also will reflect on the worthiness of research goals themselves and their relationship to a broader view of what it means to be human and to live in society. Just as there is more to being human than the pragmatic demands of daily life, there is more at issue with knowledge production than finding the most efficient ways to satisfy consumer preferences or fix near-term policy problems. We will conclude by calling for a balanced approach to funding research that addresses society's most pressing needs but also supports innovative research with less immediately apparent application.

Social relevance enhances memory for impressions in older adults.

Previous research has demonstrated that older adults have difficulty retrieving contextual material over items alone. Recent research suggests this deficit can be reduced by adding emotional context, allowing for the possibility that memory for social impressions may show less age-related decline than memory for other types of contextual information. Two studies investigated how orienting to social or self-relevant aspects of information contributed to the learning and retrieval of impressions in young and older adults. Participants encoded impressions of others in conditions varying in the use of self-reference (Experiment 1) and interpersonal meaningfulness (Experiment 2), and completed memory tasks requiring the retrieval of specific traits. For both experiments, age groups remembered similar numbers of impressions. In Experiment 1 using more self-relevant encoding contexts increased memory for impressions over orienting to stimuli in a non-social way, regardless of age. In Experiment 2 older adults had enhanced memory for impressions presented in an interpersonally meaningful relative to a personally irrelevant way, whereas young adults were unaffected by this manipulation. The results provide evidence that increasing social relevance ameliorates age differences in memory for impressions, and enhances older adults' ability to successfully retrieve contextual information.

Non-academic members of research teams, such as community members, can perceive traditional human subjects protection training as lacking in cultural relevance. We present a case exemplar of the development of a human subjects protection training for research staff with limited English proficiency and/or no or limited research experience. Seven modules were adapted for language, cultural examples, etc., from the standard Collaborative Institutional Training Initiative (CITI) human subjects protection training. Non-academic research staff completed a day-long training in human subjects protection (six modules) and our research protocol (one module). We assessed comprehension of content with PowerPoint slides and module quizzes. All participants successfully passed each module quiz with ≥ 80% correct. Questions answered incorrectly were discussed before proceeding to the next module. To meet the increasing demand for collaborative community-engaged research with underserved minority populations, human subjects protection training protocols can be adapted successfully to reflect real-world situations and provide culturally relevant materials to help non-academic research staff better understand the importance and necessity of research ethics.

Interpretation and use of evidence in state policymaking: a qualitative analysis.

Apollonio, Dorie E; Bero, Lisa A

Researchers advocating for evidence-informed policy have attempted to encourage policymakers to develop a greater understanding of research and researchers to develop a better understanding of the policymaking process. Our aim was to apply findings drawn from studies of the policymaking process, specifically the theory of policy windows, to identify strategies used to integrate evidence into policymaking and points in the policymaking process where evidence was more or less relevant. Our observational study relied on interviews conducted with 24 policymakers from the USA who had been trained to interpret scientific research in multiple iterations of an evidence-based workshop. Participants were asked to describe cases where they had been involved in making health policy and to provide examples in which research was used, either successfully or unsuccessfully. Interviews were transcribed, independently coded by multiple members of the study team and analysed for content using key words, concepts identified by participants and concepts arising from review of the texts. Our results suggest that policymakers who focused on health issues used multiple strategies to encourage evidence-informed policymaking. The respondents used a strict definition of what constituted evidence, and relied on their experience with research to discourage the use of less rigorous research. Their experience suggested that evidence was less useful in identifying problems, encouraging political action or ensuring feasibility and more useful in developing policy alternatives. Past research has suggested multiple strategies to increase the use of evidence in policymaking, including the development of rapid-response research and policy-oriented summaries of data. Our findings suggest that these strategies may be most relevant to the policymaking stream, which develops policy alternatives. In addition, we identify several strategies that policymakers and researchers can apply to encourage evidence

Introduction to evidence-based medicine(EBM)

International Nuclear Information System (INIS)

Choe, Jae Gol

2001-01-01

EBM is 'the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research.' EBM is the integration of clinical expertise, patient values, and the best evidence into the decision making process for patient care. The practice of EBM is usually triggered by patient encounters which generate questions about the effects of therapy, the utility of diagnostic tests, the prognosis of diseases, or the etiology of disorders. The best evidence is usually found in clinically relevant research that has been conducted using sound methodology. Evidence-based medicine requires new skills of the clinician, including efficient literature-searching, and the application of formal rules of evidence in evaluating the clinical literature. Evidence-based medicine converts the abstract exercise of reading and appraising the literature into the pragmatic process of using the literature to benefit individual patients while simultaneously expanding the clinician's knowledge base. This review will briefly discuss about concepts of evidence medicine and method of critical appraisal of literatures

Full Text Available L Lizarondo, K Grimmer-Somers, S KumarInternational Centre for Allied Health Evidence, University of South Australia, Adelaide, South Australia, AustraliaBackground: The use of evidence-based practice (EBP is often not reflected in allied health (AH practitioners’ day-to-day practice (the research-practice gap. Research suggests that considerable differences between and within AH disciplines exist, which require different approaches in order to influence practice behavior. It is therefore important to develop a better understanding of what influences individual AH practitioners’ adoption of evidence into daily practice.Objective: This systematic review aims to examine the individual characteristics of AH practitioners which determine their uptake of evidence into practice.Methods: Studies which examined individual factors or variables that influence research evidence use by any AH practitioner were included in the review. The methodological quality of the included papers was assessed using the Quality Assessment and Validity Tool for Cross-sectional Studies. A narrative summary of the findings was presented.Results: Six studies were included and the methodological quality scores indicated that two were weak and the remainder had moderate–weak quality. The review demonstrated that factors such as educational degree or academic qualification, involvement in research or EBP-related activities, and practitioners’ perceptions, attitudes and beliefs about research and EBP are significant predictors of self-reported research evidence use in AH. The effect of other factors such as professional characteristics, clinical setting/work environment, information-seeking behavior and sociodemographic variables are less clear. Whether there is an interaction effect between evidence-uptake factors has not been tested.Conclusion: Improving the research knowledge of clinicians and overcoming negative attitudes toward EBP have the potential to move AH

Evidence-based practice curriculum in allied health professions for teaching-research-practice nexus.

Asokan, G V

2012-11-01

Allied healthcare workers are from diverse professions and the key skill required is providing evidence-based care but this concept has not permeated enough for using it skillfully in their professions. A well structured curriculum in allied health professions is needed to strengthen concerted teaching, research, and practice to empower their professionals and make considerable differences in the lives of people by adopting evidence-based practice. Information sources for allied health professionals have relied on advice of their supervisors and colleagues, personal experiences, authoritative theory and texts for practice. Because of "research-practice" gap, often the use of evidence is not reflected in an individual day to day professional practice. Although allied health professionals work in resource and evidence challenged settings, there are certain barriers and facilitators, which need to be addressed. To implement practice-related research findings and uptake of evidence requires two essential components, namely, practical component and knowledge component. Research bench marking and research metrics for quality assurance and standardization through evidence-based practice will promote academic status and credibility of allied health profession. © 2012 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

A Growing Consensus for Change in Interpretation of Clinical Research Evidence.

Science.gov (United States)

Wilkerson, Gary B; Denegar, Craig R

2018-03-01

  The paradigm of evidence-based practice (EBP) is well established among the health care professions, but perspectives on the best methods for acquiring, analyzing, appraising, and using research evidence are evolving.   The EBP paradigm has shifted away from a hierarchy of research-evidence quality to recognize that multiple research methods can yield evidence to guide clinicians and patients through a decision-making process. Whereas the "frequentist" approach to data interpretation through hypothesis testing has been the dominant analytical method used by and taught to athletic training students and scholars, this approach is not optimal for integrating evidence into routine clinical practice. Moreover, the dichotomy of rejecting, or failing to reject, a null hypothesis is inconsistent with the Bayesian-like clinical decision-making process that skilled health care providers intuitively use. We propose that data derived from multiple research methods can be best interpreted by reporting a credible lower limit that represents the smallest treatment effect at a specified level of certainty, which should be judged in relation to the smallest effect considered to be clinically meaningful. Such an approach can provide a quantifiable estimate of certainty that an individual patient needs follow-up attention to prevent an adverse outcome or that a meaningful level of therapeutic benefit will be derived from a given intervention.   The practice of athletic training will be influenced by the evolution of the EBP paradigm. Contemporary practice will require clinicians to expand their critical-appraisal skills to effectively integrate the results derived from clinical research into the care of individual patients. Proper interpretation of a credible lower limit value for a magnitude ratio has the potential to increase the likelihood of favorable patient outcomes, thereby advancing the practice of evidence-based athletic training.

Previous surveys of organizations that support the development of evidence-informed health policies have focused on organizations that produce clinical practice guidelines (CPGs) or undertake health technology assessments (HTAs). Only rarely have surveys focused at least in part on units that directly support the use of research evidence in developing health policy on an international, national, and state or provincial level (i.e., government support units, or GSUs) that are in some way successful or innovative or that support the use of research evidence in low- and middle-income countries (LMICs). We drew on many people and organizations around the world, including our project reference group, to generate a list of organizations to survey. We modified a questionnaire that had been developed originally by the Appraisal of Guidelines, Research and Evaluation in Europe (AGREE) collaboration and adapted one version of the questionnaire for organizations producing CPGs and HTAs, and another for GSUs. We sent the questionnaire by email to 176 organizations and followed up periodically with non-responders by email and telephone. We received completed questionnaires from 152 (86%) organizations. More than one-half of the organizations (and particularly HTA agencies) reported that examples from other countries were helpful in establishing their organization. A higher proportion of GSUs than CPG- or HTA-producing organizations involved target users in the selection of topics or the services undertaken. Most organizations have few (five or fewer) full-time equivalent (FTE) staff. More than four-fifths of organizations reported providing panels with or using systematic reviews. GSUs tended to use a wide variety of explicit valuation processes for the research evidence, but none with the frequency that organizations producing CPGs, HTAs, or both prioritized evidence by its quality. Between one-half and two-thirds of organizations do not collect data systematically about

Passage relevance models for genomics search

Frieder Ophir

2009-03-01

Full Text Available Abstract We present a passage relevance model for integrating syntactic and semantic evidence of biomedical concepts and topics using a probabilistic graphical model. Component models of topics, concepts, terms, and document are represented as potential functions within a Markov Random Field. The probability of a passage being relevant to a biologist's information need is represented as the joint distribution across all potential functions. Relevance model feedback of top ranked passages is used to improve distributional estimates of query concepts and topics in context, and a dimensional indexing strategy is used for efficient aggregation of concept and term statistics. By integrating multiple sources of evidence including dependencies between topics, concepts, and terms, we seek to improve genomics literature passage retrieval precision. Using this model, we are able to demonstrate statistically significant improvements in retrieval precision using a large genomics literature corpus.

Latinos constitute the largest ethnic minority group in the United States. However, the cultural adaptation and dissemination of evidence-based parenting interventions among Latino populations continues to be scarce despite extensive research that demonstrates the long-term positive effects of these interventions. The purpose of this article is threefold: (1) justify the importance of cultural adaptation research as a key strategy to disseminate efficacious interventions among Latinos, (2) describe the initial steps of a program of prevention research with Latino immigrants aimed at culturally adapting an evidence-based intervention informed by parent management training principles, and (3) discuss implications for advancing cultural adaptation prevention practice and research, based on the initial feasibility and cultural acceptability findings of the current investigation. © FPI, Inc.

Helplessness: a systematic translational review of theory and evidence for its relevance to understanding and treating depression.

Pryce, Christopher R; Azzinnari, Damiano; Spinelli, Simona; Seifritz, Erich; Tegethoff, Marion; Meinlschmidt, Gunther

2011-12-01

Helplessness is a major concept in depression and a major theme in preclinical and clinical depression research. For example, in rodents and humans, the learned helplessness (LH) effect describes a specific deficit in behaviour to control aversive stimuli that is induced by prior exposure to uncontrollable aversive stimuli. The LH effect is objective and valid in that the cause of the behavioural deficit, namely uncontrollability, is clear; furthermore, the deficit induced is underlain by emotional, motivational and cognitive processes that are relevant to depression psychopathology. As a further example, helplessness, hopelessness, external locus of control and causal attribution are inter-related and major themes in psychological theories (primarily cognitive theories) of depression. Despite this broad interest in helplessness, it can be argued that its potential usefulness as a scientific and clinical concept has so far not been investigated optimally, including with respect to its application in research aimed at development of improved anti-depressant pharmacotherapy. The first aim of this review was to describe and integrate the psychological evidence and the neurobiological evidence for the LH effect in rodents and healthy humans and for helplessness in depressed patients. The second aim was to conduct three systematic reviews, namely of rodent studies of the LH effect, rodent studies of effects of psychopharmacological agents on the LH effect, and human studies of efficacy of pharmacotherapeutic and psychotherapeutic treatment on helplessness in depressed patients. With respect to the first aim, the major findings are: the specificity of the LH effect in otherwise non-manipulated rodents and healthy humans has been under-estimated, and the LH effect is a specific learned aversive uncontrollability (LAU) effect. There is theoretical and empirical support for a model in which a specific LAU effect induced by a life event of major emotional significance can

The Global Forum 2015 panel session dialogue entitled "From evidence to policy - thinking outside the box" was held on 26 August 2015 in the Philippines to debate why evidence was not fully translated into policy and practice and what could be done to increase its uptake. This paper reports the reasons and possible actions for increasing the uptake of evidence, and highlights the actions partners could take to increase the use of evidence in the African Region. The Global Forum 2015 debate attributed African Region's low uptake of evidence to the big gap in incentives and interests between research for health researchers and public health policy-makers; limited appreciation on the side of researchers that public health decisions are based on multiple and complex considerations; perception among users that research evidence is not relevant to local contexts; absence of knowledge translation platforms; sub-optimal collaboration and engagement between industry and research institutions; lack of involvement of civil society organizations; lack of engagement of communities in the research process; failure to engage the media; limited awareness and debate in national and local parliaments on the importance of investing in research and innovation; and dearth of research and innovation parks in the African Region. The actions needed in the Region to increase the uptake of evidence in policy and practice include strengthening NHRS governance; bridging the motivation gap between researchers and health policy-makers; restoring trust between researchers and decision-makers; ensuring close and continuous intellectual intercourse among researchers, ministry of health policy-makers and technocrats during the life course of research projects or programmes; proactive collaboration between academia and industry; regular briefings of civil society, media, relevant parliamentary committees and development partners; development of vibrant knowledge translation platforms; development of

Evidence-based Nursing Education - a Systematic Review of Empirical Research

2011-01-01

The project „Evidence-based Nursing Education – Preparatory Stage“, funded by the Landesstiftung Baden-Württemberg within the programme Impulsfinanzierung Forschung (Funding to Stimulate Research), aims to collect information on current research concerned with nursing education and to process existing data. The results of empirical research which has already been carried out were systematically evaluated with aim of identifying further topics, fields and matters of interest for empirical research in nursing education. In the course of the project, the available empirical studies on nursing education were scientifically analysed and systematised. The over-arching aim of the evidence-based training approach – which extends beyond the aims of this project - is the conception, organisation and evaluation of vocational training and educational processes in the caring professions on the basis of empirical data. The following contribution first provides a systematic, theoretical link to the over-arching reference framework, as the evidence-based approach is adapted from thematically related specialist fields. The research design of the project is oriented towards criteria introduced from a selection of studies and carries out a two-stage systematic review of the selected studies. As a result, the current status of research in nursing education, as well as its organisation and structure, and questions relating to specialist training and comparative education are introduced and discussed. Finally, the empirical research on nursing training is critically appraised as a complementary element in educational theory/psychology of learning and in the ethical tradition of research. This contribution aims, on the one hand, to derive and describe the methods used, and to introduce the steps followed in gathering and evaluating the data. On the other hand, it is intended to give a systematic overview of empirical research work in nursing education. In order to preserve a

Opinion polls show that the European Union citizens are increasingly concerned about the impact of environmental factors on their health. In order to respond and provide solid scientific evidence for the numerous policies related to the protection of human health and the environment managed at the Union level, the European Union made a substantial investment in research and innovation in the past two decades through its Framework Programmes for Research and Technological Development, including the current programme, Horizon 2020, which started in 2014. This policy review paper analysed the portfolio of forty collaborative projects relevant to environment and health, which received a total amount of around 228 million euros from the EU. It gives details on their contents and general scientific trends observed, the profiles of the participating countries and institutions, and the potential policy implications of the results obtained. The increasing knowledge base is needed to make informed policy decisions in Europe and beyond, and should be useful to many stakeholders including the scientific community and regulatory authorities.

Fidelity in Animal Modeling: Prerequisite for a Mechanistic Research Front Relevant to the Inflammatory Incompetence of Acute Pediatric Malnutrition

Science.gov (United States)

Woodward, Bill

2016-01-01

Inflammatory incompetence is characteristic of acute pediatric protein-energy malnutrition, but its underlying mechanisms remain obscure. Perhaps substantially because the research front lacks the driving force of a scholarly unifying hypothesis, it is adrift and research activity is declining. A body of animal-based research points to a unifying paradigm, the Tolerance Model, with some potential to offer coherence and a mechanistic impetus to the field.

Inflammatory incompetence is characteristic of acute pediatric protein-energy malnutrition, but its underlying mechanisms remain obscure. Perhaps substantially because the research front lacks the driving force of a scholarly unifying hypothesis, it is adrift and research activity is declining. A body of animal-based research points to a unifying paradigm, the Tolerance Model, with some potential to offer coherence and a mechanistic impetus to the field. However, reasonable skepticism prevails regarding the relevance of animal models of acute pediatric malnutrition; consequently, the fundamental contributions of the animal-based component of this research front are largely overlooked. Design-related modifications to improve the relevance of animal modeling in this research front include, most notably, prioritizing essential features of pediatric malnutrition pathology rather than dietary minutiae specific to infants and children, selecting windows of experimental animal development that correspond to targeted stages of pediatric immunological ontogeny, and controlling for ontogeny-related confounders.

In their seminal paper 'Is our self nothing but reward', Northoff and Hayes (Biol Psychiatry 69(11):1019-1025, Northoff, Hayes, Biological Psychiatry 69(11):1019-1025, 2011) proposed three models of the relationship between self and reward and opened a continuing debate about how these different fields can be linked. To date, none of the proposed models received strong empirical support. The present study tested common and distinct effects of personal relevance and reward values by de-componenting different stages of perceptual decision making using a drift-diffusion approach. We employed a recently developed associative matching paradigm where participants (N = 40) formed mental associations between five geometric shapes and five labels referring personal relevance in the personal task, or five shape-label pairings with different reward values in the reward task and then performed a matching task by indicating whether a displayed shape-label pairing was correct or incorrect. We found that common effects of personal relevance and monetary reward were manifested in the facilitation of behavioural performance for high personal relevance and high reward value as socially important signals. The differential effects between personal and monetary relevance reflected non-decisional time in a perceptual decision process, and task-specific prioritization of stimuli. Our findings support the parallel processing model (Northoff & Hayes, Biol Psychiatry 69(11):1019-1025, Northoff, Hayes, Biological Psychiatry 69(11):1019-1025, 2011) and suggest that self-specific processing occurs in parallel with high reward processing. Limitations and further directions are discussed.

Full Text Available BackgroundHistorically, HIV prevention efforts in Nepal have primarily focused on heterosexual transmission, particularly, among female sex workers (FSWs and their male clients, with little acknowledgment of the contribution of migrant workers to the epidemic. The very few HIV prevention efforts that have been attempted with migrants have been unsuccessful primarily due to stigma, discrimination, and insufficient availability of culturally relevant evidence-based interventions (EBIs. As an initial step toward addressing this unmet need, we conducted formative research aimed at adapting an evidence-based HIV risk reduction intervention for implementation among migrants in Nepal.MethodsOur formative work involved a critical examination of established EBIs and associated published reports complemented by data elicited through structured interviews with members of the target population and key stakeholders. Between July and August, 2014, we conducted structured one-on-one interview with migrants (n = 5 and key stakeholder (e.g., counselors, field workers, and project coordinator; n = 5, which focused on the HIV risk profiles of the migrants and on ways to optimize intervention content, delivery, and placement within the community-based settings. Data analysis followed a thematic analysis approach utilizing several qualitative data analysis techniques, including inductive analysis, cross-case analysis, and analytical coding of textual data.ResultsBased on formative research, we adapted the Holistic Health Recovery Program (HHRP, an EBI, to consist of four 30-minute sessions that cover a range of topics relevant to migrants in Nepal. The intervention was adapted with flexibility so that it could be provided in an individual format, implemented within or outside the CBO, and can be delivered in either consecutive or weekly sessions based on time constraints. ConclusionsThis paper provides a detailed description of the formative research process

Striving to foster collaboration among countries suffering from maternal and child health (MCH) inequities, the MASCOT project mapped and analyzed the use of research in strategies tackling them in 11 low- and middle-income countries. This article aims to present the way in which research influenced MCH policies and programs in six of these countries - three in Africa and three in Latin America. Qualitative research using a thematic synthesis narrative process was used to identify and describe who is producing what kind of research, how research is funded, how inequities are approached by research and policies, the countries' research capacities, and the type of evidence base that MCH policies and programs use. Four tools were designed for these purposes: an online survey for researchers, a semi-structured interview with decision makers, and two content analysis guides: one for policy and programs documents and one for scientific articles. Three modalities of research utilization were observed in the strategies tackling MCH inequities in the six included countries - instrumental, conceptual and symbolic. Instrumental utilization directly relates the formulation and contents of the strategies with research results, and is the least used within the analyzed policies and programs. Even though research is considered as an important input to support decision making and most of the analyzed countries count five or six relevant MCH research initiatives, in most cases, the actual impact of research is not clearly identifiable. While MCH research is increasing in low- and middle-income countries, the impact of its outcomes on policy formulation is low. We did not identify a direct relationship between the nature of the financial support organizations and the kind of evidence utilization within the policy process. There is still a visible gap between researchers and policymakers regarding their different intentions to link evidence and decision making processes.

Little is known about how well or under what conditions health innovations are sustained and their gains maintained once they are put into practice. Implementation science typically focuses on uptake by early adopters of one healthcare innovation at a time. The later-stage challenges of scaling up and sustaining evidence-supported interventions receive too little attention. This project identifies the challenges associated with sustainability research and generates recommendations for accelerating and strengthening this work. A multi-method, multi-stage approach, was used: (1) identifying and recruiting experts in sustainability as participants, (2) conducting research on sustainability using concept mapping, (3) action planning during an intensive working conference of sustainability experts to expand the concept mapping quantitative results, and (4) consolidating results into a set of recommendations for research, methodological advances, and infrastructure building to advance understanding of sustainability. Participants comprised researchers, funders, and leaders in health, mental health, and public health with shared interest in the sustainability of evidence-based health care. Prompted to identify important issues for sustainability research, participants generated 91 distinct statements, for which a concept mapping process produced 11 conceptually distinct clusters. During the conference, participants built upon the concept mapping clusters to generate recommendations for sustainability research. The recommendations fell into three domains: (1) pursue high priority research questions as a unified agenda on sustainability; (2) advance methods for sustainability research; (3) advance infrastructure to support sustainability research. Implementation science needs to pursue later-stage translation research questions required for population impact. Priorities include conceptual consistency and operational clarity for measuring sustainability, developing evidence

Improving the use of research evidence in guideline development: 12. Incorporating considerations of equity.

The World Health Organization (WHO), like many other organisations around the world, has recognised the need to use more rigorous processes to ensure that health care recommendations are informed by the best available research evidence. This is the 12th of a series of 16 reviews that have been prepared as background for advice from the WHO Advisory Committee on Health Research to WHO on how to achieve this. We reviewed the literature on incorporating considerations of equity in guidelines and recommendations. We searched PubMed and three databases of methodological studies for existing systematic reviews and relevant methodological research. We did not conduct systematic reviews ourselves. Our conclusions are based on the available evidence, consideration of what WHO and other organisations are doing and logical arguments. We found few directly relevant empirical methodological studies. These answers are based largely on logical arguments. When and how should inequities be addressed in systematic reviews that are used as background documents for recommendations? The following question should routinely be considered: Are there plausible reasons for anticipating differential relative effects across disadvantaged and advantaged populations? If there are plausible reasons for anticipating differential effects, additional evidence should be included in a review to inform judgments about the likelihood of differential effects. What questions about equity should routinely be addressed by those making recommendations on behalf of WHO? The following additional questions should routinely be considered: How likely is it that the results of available research are applicable to disadvantaged populations and settings? How likely are differences in baseline risk that would result in differential absolute effects across disadvantaged and advantaged populations? How likely is it that there are important differences in trade-offs between the expected benefits and harms across

Models of policy-making and their relevance for drug research.

Researchers are often frustrated by their inability to influence policy. We describe models of policy-making to provide new insights and a more realistic assessment of research impacts on policy. We describe five prominent models of policy-making and illustrate them with examples from the alcohol and drugs field, before drawing lessons for researchers. Policy-making is a complex and messy process, with different models describing different elements. We start with the incrementalist model, which highlights small amendments to policy, as occurs in school-based drug education. A technical/rational approach then outlines the key steps in a policy process from identification of problems and their causes, through to examination and choice of response options, and subsequent implementation and evaluation. There is a clear role for research, as we illustrate with the introduction of new medications, but this model largely ignores the dominant political aspects of policy-making. Such political aspects include the influence of interest groups, and we describe models about power and pressure groups, as well as advocacy coalitions, and the challenges they pose for researchers. These are illustrated with reference to the alcohol industry, and interest group conflicts in establishing a Medically Supervised Injecting Centre. Finally, we describe the multiple streams framework, which alerts researchers to 'windows of opportunity', and we show how these were effectively exploited in policy for cannabis law reform in Western Australia. Understanding models of policy-making can help researchers maximise the uptake of their work and advance evidence-informed policy.

Single cell biology beyond the era of antibodies: relevance, challenges, and promises in biomedical research.

Abraham, Parvin; Maliekal, Tessy Thomas

2017-04-01

Research of the past two decades has proved the relevance of single cell biology in basic research and translational medicine. Successful detection and isolation of specific subsets is the key to understand their functional heterogeneity. Antibodies are conventionally used for this purpose, but their relevance in certain contexts is limited. In this review, we discuss some of these contexts, posing bottle neck for different fields of biology including biomedical research. With the advancement of chemistry, several methods have been introduced to overcome these problems. Even though microfluidics and microraft array are newer techniques exploited for single cell biology, fluorescence-activated cell sorting (FACS) remains the gold standard technique for isolation of cells for many biomedical applications, like stem cell therapy. Here, we present a comprehensive and comparative account of some of the probes that are useful in FACS. Further, we illustrate how these techniques could be applied in biomedical research. It is postulated that intracellular molecular markers like nucleostemin (GNL3), alkaline phosphatase (ALPL) and HIRA can be used for improving the outcome of cardiac as well as bone regeneration. Another field that could utilize intracellular markers is diagnostics, and we propose the use of specific peptide nucleic acid probes (PNPs) against certain miRNAs for cancer surgical margin prediction. The newer techniques for single cell biology, based on intracellular molecules, will immensely enhance the repertoire of possible markers for the isolation of cell types useful in biomedical research.

Better Outcomes through Learning, Data, Engagement, and Research (BOLDER – a system for improving evidence and clinical practice in low and middle income countries [version 1; referees: 2 approved

Full Text Available Despite the many thousands of research studies published every year, evidence for making clinical decisions is often lacking. The main problem is that the evidence available is generated in conditions very different from those that prevail in routine clinical practice and with patients who are different. This is particularly a problem for low and middle income countries as most evidence is generated in high income countries. A group of clinicians, researchers, and policy makers met at Bellagio in Italy to consider how more relevant evidence might be generated. One answer is to conduct more pragmatic trials—those undertaken in routine clinical practice. The group thought that this might best be achieved by developing “learning health systems” in low and middle income countries. Learning health systems develop in communities that include clinicians, patients, researchers, improvement specialists, information technology specialists, managers, and policy makers and have a governance system that gives a voice to all those in the community. The systems focus on improving outcomes for patients, use a common dataset, and promote quality improvement and pragmatic research. Plans have been developed to create at least two learning systems in Africa.

Mehta, S.K.; Venkatraj, V.

1988-01-01

The Indian Nuclear Power Programme envisages three important stages viz., installation of thermal reactors, fast reactors and utilization of Thorium. By the year 2000 AD, it is proposed to have an installed total capacity of nuclear power of about 10,000 MWe. Starting from the present installed capacity of 1330 MWe, the additional contribution will be mainly made by thermal power reactors of the Pressurized Heavy Water type (PHWR). Apart from the reactors presently under construction about 12 numbers of 235 MWe units are planned to be constructed, which will be based on the standardized design of the reactors at Narora Atomic Power Project (NAPP). In addition, 10 units of 500 MWe capacity each, the design for which is currently under progress, will also be installed. The design, construction and operating agency is the Nuclear Power Board (NPB), while the Bhabha Atomic Research Centre (BARC) is responsible for the research and development work required. In addition to the programme on thermal power reactors, a thermal research reactor (DHRUVA) of 100 MWth capacity has been designed, constructed and has been commissioned. Some of the important heat transfer and fluid flow research problems relevant to the Indian nuclear power and research reactors are discussed in this paper

2017-01-01

Background and aims Recently, digital research is very popular in schools. The capacity of students to do an effective search is unclear which can lead to utilization of unacceptable evidence in their research. Aims To evaluate middle school students' effective search skills. Methods This survey was done during the summer school of Farzanegan talented students middle school. The self-administrated questionnaire studied 30 items about effective search and digital research skills of students. One hundred questionnaires were distributed in this summer school and students in the 7th and 8th grades filled the questionnaires. The administration of the questionnaire was counted as their concept. All data was analyzed at Excel 2013. Results Eighty percent of students including 67.5% of the seventh and 32.5% of the eighth grade students responded to the questionnaires respectively. Shockingly, 96.2% of students only googled and most of them (73.7%) type the topic of their research in Persian to start their research strategy. More than half of them (52.5) believed the result of their search is mostly or always correct and 66.2% of them copy-pasted their findings without any assessment. Surprisingly, only 27.5% of them have proposed that they had problem with appraising the evidence. The best sources of the students for finding the answer of their questions were: Wikipedia, telegram, TV, books, E-Books, YouTube, classmates, Facebook and student information websites, and EBSCO, accordingly. 76.2% acknowledged that internet has turned students into copy machines. Only 31.2% agreed their teachers taught them how to do effective research. Conclusion Most of the students were not familiar with valid sources of research evidence. Language barrier may limit their access to best evidence. Most students were not used to retrieving the evidence.

Full Text Available Abstract Background Previous surveys of organizations that support the development of evidence-informed health policies have focused on organizations that produce clinical practice guidelines (CPGs or undertake health technology assessments (HTAs. Only rarely have surveys focused at least in part on units that directly support the use of research evidence in developing health policy on an international, national, and state or provincial level (i.e., government support units, or GSUs that are in some way successful or innovative or that support the use of research evidence in low- and middle-income countries (LMICs. Methods We drew on many people and organizations around the world, including our project reference group, to generate a list of organizations to survey. We modified a questionnaire that had been developed originally by the Appraisal of Guidelines, Research and Evaluation in Europe (AGREE collaboration and adapted one version of the questionnaire for organizations producing CPGs and HTAs, and another for GSUs. We sent the questionnaire by email to 176 organizations and followed up periodically with non-responders by email and telephone. Results We received completed questionnaires from 152 (86% organizations. More than one-half of the organizations (and particularly HTA agencies reported that examples from other countries were helpful in establishing their organization. A higher proportion of GSUs than CPG- or HTA-producing organizations involved target users in the selection of topics or the services undertaken. Most organizations have few (five or fewer full-time equivalent (FTE staff. More than four-fifths of organizations reported providing panels with or using systematic reviews. GSUs tended to use a wide variety of explicit valuation processes for the research evidence, but none with the frequency that organizations producing CPGs, HTAs, or both prioritized evidence by its quality. Between one-half and two-thirds of organizations

From science to action: Principles for undertaking environmental research that enables knowledge exchange and evidence-based decision-making.

Cvitanovic, C; McDonald, J; Hobday, A J

2016-12-01

Effective conservation requires knowledge exchange among scientists and decision-makers to enable learning and support evidence-based decision-making. Efforts to improve knowledge exchange have been hindered by a paucity of empirically-grounded guidance to help scientists and practitioners design and implement research programs that actively facilitate knowledge exchange. To address this, we evaluated the Ningaloo Research Program (NRP), which was designed to generate new scientific knowledge to support evidence-based decisions about the management of the Ningaloo Marine Park in north-western Australia. Specifically, we evaluated (1) outcomes of the NRP, including the extent to which new knowledge informed management decisions; (2) the barriers that prevented knowledge exchange among scientists and managers; (3) the key requirements for improving knowledge exchange processes in the future; and (4) the core capacities that are required to support knowledge exchange processes. While the NRP generated expansive and multidisciplinary science outputs directly relevant to the management of the Ningaloo Marine Park, decision-makers are largely unaware of this knowledge and little has been integrated into decision-making processes. A range of barriers prevented efficient and effective knowledge exchange among scientists and decision-makers including cultural differences among the groups, institutional barriers within decision-making agencies, scientific outputs that were not translated for decision-makers and poor alignment between research design and actual knowledge needs. We identify a set of principles to be implemented routinely as part of any applied research program, including; (i) stakeholder mapping prior to the commencement of research programs to identify all stakeholders, (ii) research questions to be co-developed with stakeholders, (iii) implementation of participatory research approaches, (iv) use of a knowledge broker, and (v) tailored knowledge management

Evidence-informed capacity building for setting health priorities in low- and middle-income countries: A framework and recommendations for further research [version 1; referees: 2 approved

Full Text Available Priority-setting in health is risky and challenging, particularly in resource-constrained settings. It is not simply a narrow technical exercise, and involves the mobilisation of a wide range of capacities among stakeholders – not only the technical capacity to “do” research in economic evaluations. Using the Individuals, Nodes, Networks and Environment (INNE framework, we identify those stakeholders, whose capacity needs will vary along the evidence-to-policy continuum. Policymakers and healthcare managers require the capacity to commission and use relevant evidence (including evidence of clinical and cost-effectiveness, and of social values; academics need to understand and respond to decision-makers’ needs to produce relevant research. The health system at all levels will need institutional capacity building to incentivise routine generation and use of evidence. Knowledge brokers, including priority-setting agencies (such as England’s National Institute for Health and Care Excellence, and Health Interventions and Technology Assessment Program, Thailand and the media can play an important role in facilitating engagement and knowledge transfer between the various actors. Especially at the outset but at every step, it is critical that patients and the public understand that trade-offs are inherent in priority-setting, and careful efforts should be made to engage them, and to hear their views throughout the process. There is thus no single approach to capacity building; rather a spectrum of activities that recognises the roles and skills of all stakeholders. A range of methods, including formal and informal training, networking and engagement, and support through collaboration on projects, should be flexibly employed (and tailored to specific needs of each country to support institutionalisation of evidence-informed priority-setting. Finally, capacity building should be a two-way process; those who build capacity should also attend to

Latinos constitute the largest ethnic minority group in the US. However, the cultural adaptation and dissemination of evidence-based parenting interventions among Latino populations continues to be scarce in spite of extensive research that demonstrates the long-term positive effects of these interventions. The purpose of this article is threefold: (a) justify the importance of cultural adaptation research as a key strategy to disseminate efficacious interventions among Latinos, (b) describe the initial steps of a program of prevention research with Latino immigrants aimed at culturally adapting an evidence-based intervention informed by parent management training (PMT) principles, and (c) discuss implications for advancing cultural adaptation prevention practice and research, based on the initial feasibility and cultural acceptability findings of the current investigation.

Discussions within the health community routinely emphasise the importance of evidence in informing policy formulation and implementation. Much of the support for the evidence-based policy movement draws from concern that policy decisions are often based on inadequate engagement with high-quality evidence. In many such discussions, evidence is treated as differing only in quality, and assumed to improve decisions if it can only be used more. In contrast, political science scholars have described this as an overly simplistic view of the policy-making process, noting that research 'use' can mean a variety of things and relies on nuanced aspects of political systems. An approach more in recognition of how policy-making systems operate in practice can be to consider how institutions and ideas influence which pieces of evidence appear to be relevant for, and are used within, different policy processes. Drawing on in-depth interviews undertaken in 2015-2016 with key health sector stakeholders in Cambodia, we investigate the evidence perceived to be relevant to policy decisions for three contrasting health policy examples, namely tobacco control, HIV/AIDS and performance-based salary incentives. These cases allow us to examine the ways that policy-relevant evidence may differ given the framing of the issue and the broader institutional context in which evidence is considered. The three health issues show few similarities in how pieces of evidence were used in various aspects of policy-making, despite all being discussed within a broad policy environment in which evidence-based policy-making is rhetorically championed. Instead, we find that evidence use can be better understood by mapping how these health policy issues differ in terms of the issue characteristics, and also in terms of the stakeholders structurally established as having a dominant influence for each issue. Both of these have important implications for evidence use. Contrasting concerns of key stakeholders

The lecture explores the origins of evidence-based practice (EBP) in health sciences librarianship beginning with examples from the work of Janet Doe and past Doe lecturers. Additional sources of evidence are used to document the rise of research and EBP as integral components of our professional work. FOUR SOURCES OF EVIDENCE ARE USED TO EXAMINE THE RISE OF EBP: (1) a publication by Doe and research-related content in past Doe lectures, (2) research-related word usage in articles in the Bulletin of the Medical Library Association and Journal of the Medical Library Association between 1961 and 2010, (3) Medical Library Association activities, and (4) EBP as an international movement. These sources of evidence confirm the rise of EBP in health sciences librarianship. International initiatives sparked the rise of evidence-based librarianship and continue to characterize the movement. This review shows the emergence of a unique form of EBP that, although inspired by evidence-based medicine (EBM), has developed its own view of evidence and its application in library and information practice. Health sciences librarians have played a key role in initiating, nurturing, and spreading EBP in other branches of our profession. Our close association with EBM set the stage for developing our own EBP. While we relied on EBM as a model for our early efforts, we can observe the continuing evolution of our own unique approach to using, creating, and applying evidence from a variety of sources to improve the quality of health information services.

Complex wounds such as leg and foot ulcers are common, resource intensive and have negative impacts on patients' wellbeing. Evidence-based decision-making, substantiated by high quality evidence such as from systematic reviews, is widely advocated for improving patient care and healthcare efficiency. Consequently, we set out to classify and map the extent to which up-to-date systematic reviews containing robust evidence exist for wound care uncertainties prioritised by community-based healthcare professionals. We asked healthcare professionals to prioritise uncertainties based on complex wound care decisions, and then classified 28 uncertainties according to the type and level of decision. For each uncertainty, we searched for relevant systematic reviews. Two independent reviewers screened abstracts and full texts of reviews against the following criteria: meeting an a priori definition of a systematic review, sufficiently addressing the uncertainty, published during or after 2012, and identifying high quality research evidence. The most common uncertainty type was 'interventions' 24/28 (85%); the majority concerned wound level decisions 15/28 (53%) however, service delivery level decisions (10/28) were given highest priority. Overall, we found 162 potentially relevant reviews of which 57 (35%) were not systematic reviews. Of 106 systematic reviews, only 28 were relevant to an uncertainty and 18 of these were published within the preceding five years; none identified high quality research evidence. Despite the growing volume of published primary research, healthcare professionals delivering wound care have important clinical uncertainties which are not addressed by up-to-date systematic reviews containing high certainty evidence. These are high priority topics requiring new research and systematic reviews which are regularly updated. To reduce clinical and research waste, we recommend systematic reviewers and researchers make greater efforts to ensure that research

To eliminate health disparities in the United States, identifying cultural contexts salient to the target populations in an intervention study is critical; however, little research has been conducted on the identification of cultural contexts among Korean Americans who have significant risk factors for chronic diseases. This systematic review identifies critical cultural contexts central to the literature discussed in health research on Korean Americans. We examined 14 research reports of 801 potentially eligible articles published between 2000 and 2016 and analyzed their contribution to cultural contexts among Korean Americans based on the PEN-3 model. This review highlights how cultural contexts impact health and health behaviors of Korean Americans, and may contribute to health disparities in the United States. The key cultural contexts highlighted in this review include social support/social network, family, gender role expectations, and a holistic view of health and illness. These cultural contexts should be incorporated in designing culturally relevant, effective, and sustainable health interventions for Korean Americans, which will contribute to eliminating health disparities for this ethnic group who experience great obstacles to healthcare access and healthy behaviors.

Use of Neutron Beams for Materials Research Relevant to the Nuclear Energy Sector

International Nuclear Information System (INIS)

2015-10-01

Nuclear technologies such as fission and fusion reactors, including associated waste storage and disposal, rely on the availability of not only nuclear fuels but also advanced structural materials. In 2010–2013, the IAEA organized and implemented the Coordinated Research Project (CRP) on Development, Characterization and Testing of Materials of Relevance to Nuclear Energy Sector Using Neutron Beams. A total of 19 institutions from 18 Member States (Argentina, Australia, Brazil, China, Czech Republic, France, Germany, Hungary, Indonesia, Italy, Japan, Netherlands, Republic of Korea, Romania, Russian Federation (two institutions), South Africa, Switzerland and United States of America) cooperated with the main objective to address the use of various neutron beam techniques for characterization, testing and qualification of materials and components produced or under development for applications in the nuclear energy sector. This CRP aimed to bring stakeholders and end users of research reactors and accelerator based neutron sources together for the enhanced use of available facilities and development of new infrastructures for applied materials research. Work envisioned under this CRP was related to the optimization and validation of neutron beam techniques, including facility and instrument modifications/optimizations as well as improved data acquisition, processing and analysis systems. Particular emphasis was placed on variable environments during material characterization and testing as required by some applications such as intensive irradiation load, high temperature and high pressure conditions, and the presence of strong magnetic fields. Targeted neutron beam techniques were neutron diffraction, small angle neutron scattering and digital neutron radiography/tomography. This publication is a compilation of the main results and findings of the CRP, and the CD-ROM accompanying this publication contains 19 reports with additional relevant technical details

Recognizing the need for evidence to inform US Government and governments of the low- and middle-income countries on efficient, effective maternal health policies, strategies, and programmes, the US Government convened the Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives in April 2012 in Washington, DC, USA. This paper summarizes the background and methods for the acquisition and evaluation of the evidence used for achieving the goals of the Summit. The goal of the Summit was to obtain multidisciplinary expert review of literature to inform both US Government and governments of the low- and middle-income countries on evidence-informed practice, policies, and strategies for financial incentives. Several steps were undertaken to define the tasks for the Summit and identify the appropriate evidence for review. The process began by identifying focal questions intended to inform governments of the low-and middle-income countries and the US Government about the efficacy of supply- and demand-side financial incentives for enhanced provision and use of quality maternal health services. Experts were selected representing the research and programme communities, academia, relevant non-governmental organizations, and government agencies and were assembled into Evidence Review Teams. This was followed by a systematic process to gather relevant peer-reviewed literature that would inform the focal questions. Members of the Evidence Review Teams were invited to add relevant papers not identified in the initial literature review to complete the bibliography. The Evidence Review Teams were asked to comply with a specific evaluation framework for recommendations on practice and policy based on both expert opinion and the quality of the data. Details of the search processes and methods used for screening and quality reviews are described.

Evidence for the triadic model of adolescent brain development: Cognitive load and task-relevance of emotion differentially affect adolescents and adults

Directory of Open Access Journals (Sweden)

Sven C. Mueller

2017-08-01

Full Text Available In adults, cognitive control is supported by several brain regions including the limbic system and the dorsolateral prefrontal cortex (dlPFC when processing emotional information. However, in adolescents, some theories hypothesize a neurobiological imbalance proposing heightened sensitivity to affective material in the amygdala and striatum within a cognitive control context. Yet, direct neurobiological evidence is scarce. Twenty-four adolescents (12–16 and 28 adults (25–35 completed an emotional n-back working memory task in response to happy, angry, and neutral faces during fMRI. Importantly, participants either paid attention to the emotion (task-relevant condition or judged the gender (task-irrelevant condition. Behaviorally, for both groups, when happy faces were task-relevant, performance improved relative to when they were task-irrelevant, while performance decrements were seen for angry faces. In the dlPFC, angry faces elicited more activation in adults during low relative to high cognitive load (2-back vs. 0-back. By contrast, happy faces elicited more activation in the amygdala in adolescents when they were task-relevant. Happy faces also generally increased nucleus accumbens activity (regardless of relevance in adolescents relative to adults. Together, the findings are consistent with neurobiological models of adolescent brain development and identify neurodevelopmental differences in cognitive control emotion interactions.

Improving the use of research evidence in guideline development: 12. Incorporating considerations of equity

2006-12-01

Full Text Available Abstract Background The World Health Organization (WHO, like many other organisations around the world, has recognised the need to use more rigorous processes to ensure that health care recommendations are informed by the best available research evidence. This is the 12th of a series of 16 reviews that have been prepared as background for advice from the WHO Advisory Committee on Health Research to WHO on how to achieve this. Objectives We reviewed the literature on incorporating considerations of equity in guidelines and recommendations. Methods We searched PubMed and three databases of methodological studies for existing systematic reviews and relevant methodological research. We did not conduct systematic reviews ourselves. Our conclusions are based on the available evidence, consideration of what WHO and other organisations are doing and logical arguments. Key questions and answers We found few directly relevant empirical methodological studies. These answers are based largely on logical arguments. When and how should inequities be addressed in systematic reviews that are used as background documents for recommendations? • The following question should routinely be considered: Are there plausible reasons for anticipating differential relative effects across disadvantaged and advantaged populations? • If there are plausible reasons for anticipating differential effects, additional evidence should be included in a review to inform judgments about the likelihood of differential effects. What questions about equity should routinely be addressed by those making recommendations on behalf of WHO? • The following additional questions should routinely be considered: • How likely is it that the results of available research are applicable to disadvantaged populations and settings? • How likely are differences in baseline risk that would result in differential absolute effects across disadvantaged and advantaged populations? • How likely is

The mode of action human relevance (MOA/HR) framework increases transparency in systematically considering data on MOA for end (adverse) effects and their relevance to humans. This framework continues to evolve as experience increases in its application. Though the MOA/HR framework is not designed to address the question of “how much information is enough” to support a hypothesized MOA in animals or its relevance to humans, its organizing construct has potential value in considering relative weight of evidence (WOE) among different cases and hypothesized MOA(s). This context is explored based on MOA analyses in published assessments to illustrate the relative extent of supporting data and their implications for dose–response analysis and involved comparisons for chemical assessments on trichloropropane, and carbon tetrachloride with several hypothesized MOA(s) for cancer. The WOE for each hypothesized MOA was summarized in narrative tables based on comparison and contrast of the extent and nature of the supporting database versus potentially inconsistent or missing information. The comparison was based on evolved Bradford Hill considerations rank ordered to reflect their relative contribution to WOE determinations of MOA taking into account increasing experience in their application internationally. This clarification of considerations for WOE determinations as a basis for comparative analysis is anticipated to contribute to increasing consistency in the application of MOA/HR analysis and potentially, transparency in separating science judgment from public policy considerations in regulatory risk assessment.

Understanding the kinds of evidence available and using the best evidence to answer a question is critical to evidenced-based decision-making, and it requires synthesis of evidence from a variety of sources. Categorization of human system risks in spaceflight, in particular, focuses on how well the integration and interpretation of all available evidence informs the risk statement that describes the relationship between spaceflight hazards and an outcome of interest. A mature understanding and categorization of these risks requires: 1) sufficient characterization of risk, 2) sufficient knowledge to determine an acceptable level of risk (i.e., a standard), 3) development of mitigations to meet the acceptable level of risk, and 4) identification of factors affecting generalizability of the evidence to different design reference missions. In the medical research community, evidence is often ranked by increasing confidence in findings gleaned from observational and experimental research (e.g., "levels of evidence"). However, an approach based solely on aspects of experimental design is problematic in assessing human system risks for spaceflight. For spaceflight, the unique challenges and opportunities include: (1) The independent variables in most evidence are the hazards of spaceflight, such as space radiation or low gravity, which cannot be entirely duplicated in terrestrial (Earth-based) analogs, (2) Evidence is drawn from multiple sources including medical and mission operations, Lifetime Surveillance of Astronaut Health (LSAH), spaceflight research (LSDA), and relevant environmental & terrestrial databases, (3) Risk metrics based primarily on LSAH data are typically derived from available prevalence or incidence data, which may limit rigorous interpretation, (4) The timeframe for obtaining adequate spaceflight sample size (n) is very long, given the small population, (5) Randomized controlled trials are unattainable in spaceflight, (6) Collection of personal and

It can be challenging to decide which evidence synthesis software to choose when doing a systematic review. This article discusses some of the important questions to consider in relation to the chosen method and synthesis approach. Software can support researchers in a range of ways. Here, a range of review conditions and software solutions. For example, facilitating contemporaneous collaboration across time and geographical space; in-built bias assessment tools; and line-by-line coding for qualitative textual analysis. EPPI-Reviewer is a review software for research synthesis managed by the EPPI-centre, UCL Institute of Education. EPPI-Reviewer has text mining automation technologies. Version 5 supports data sharing and re-use across the systematic review community. Open source software will soon be released. EPPI-Centre will continue to offer the software as a cloud-based service. The software is offered via a subscription with a one-month (extendible) trial available and volume discounts for 'site licences'. It is free to use for Cochrane and Campbell reviews. The next EPPI-Reviewer version is being built in collaboration with National Institute for Health and Care Excellence using 'surveillance' of newly published research to support 'living' iterative reviews. This is achieved using a combination of machine learning and traditional information retrieval technologies to identify the type of research each new publication describes and determine its relevance for a particular review, domain or guideline. While the amount of available knowledge and research is constantly increasing, the ways in which software can support the focus and relevance of data identification are also developing fast. Software advances are maximising the opportunities for the production of relevant and timely reviews. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Evidence based medical imaging (EBMI)

International Nuclear Information System (INIS)

Smith, Tony

2008-01-01

Background: The evidence based paradigm was first described about a decade ago. Previous authors have described a framework for the application of evidence based medicine which can be readily adapted to medical imaging practice. Purpose: This paper promotes the application of the evidence based framework in both the justification of the choice of examination type and the optimisation of the imaging technique used. Methods: The framework includes five integrated steps: framing a concise clinical question; searching for evidence to answer that question; critically appraising the evidence; applying the evidence in clinical practice; and, evaluating the use of revised practices. Results: This paper illustrates the use of the evidence based framework in medical imaging (that is, evidence based medical imaging) using the examples of two clinically relevant case studies. In doing so, a range of information technology and other resources available to medical imaging practitioners are identified with the intention of encouraging the application of the evidence based paradigm in radiography and radiology. Conclusion: There is a perceived need for radiographers and radiologists to make greater use of valid research evidence from the literature to inform their clinical practice and thus provide better quality services

Mortality salience increases personal relevance of the norm of reciprocity.

Schindler, Simon; Reinhard, Marc-André; Stahlberg, Dagmar

2012-10-01

Research on terror management theory found evidence that people under mortality salience strive to live up to salient cultural norms and values, like egalitarianism, pacifism, or helpfulness. A basic, strongly internalized norm in most human societies is the norm of reciprocity: people should support those who supported them (i.e., positive reciprocity), and people should injure those who injured them (i.e., negative reciprocity), respectively. In an experiment (N = 98; 47 women, 51 men), mortality salience overall significantly increased personal relevance of the norm of reciprocity (M = 4.45, SD = 0.65) compared to a control condition (M = 4.19, SD = 0.59). Specifically, under mortality salience there was higher motivation to punish those who treated them unfavourably (negative norm of reciprocity). Unexpectedly, relevance of the norm of positive reciprocity remained unaffected by mortality salience. Implications and limitations are discussed.

Making research relevant? Ecological methods and the ecosystem services framework

Root-Bernstein, Meredith; Jaksic, Fabián. M.

2017-07-01

We examine some unexpected epistemological conflicts that arise at the interfaces between ecological science, the ecosystem services framework, policy, and industry. We use an example from our own research to motivate and illustrate our main arguments, while also reviewing standard approaches to ecological science using the ecosystem services framework. While we agree that the ecosystem services framework has benefits in its industrial applications because it may force economic decision makers to consider a broader range of costs and benefits than they would do otherwise, we find that many alignments of ecology with the ecosystem services framework are asking questions that are irrelevant to real-world applications, and generating data that does not serve real-world applications. We attempt to clarify why these problems arise and how to avoid them. We urge fellow ecologists to reflect on the kind of research that can lead to both scientific advances and applied relevance to society. In our view, traditional empirical approaches at landscape scales or with place-based emphases are necessary to provide applied knowledge for problem solving, which is needed once decision makers identify risks to ecosystem services. We conclude that the ecosystem services framework is a good policy tool when applied to decision-making contexts, but not a good theory either of social valuation or ecological interactions, and should not be treated as one.

Evidence-based medicine - an appropriate tool for evidence-based health policy? A case study from Norway.

Malterud, Kirsti; Bjelland, Anne Karen; Elvbakken, Kari Tove

2016-03-05

Evidence-based policy (EBP), a concept modelled on the principles of evidence-based medicine (EBM), is widely used in different areas of policymaking. Systematic reviews (SRs) with meta-analyses gradually became the methods of choice for synthesizing research evidence about interventions and judgements about quality of evidence and strength of recommendations. Critics have argued that the relation between research evidence and service policies is weak, and that the notion of EBP rests on a misunderstanding of policy processes. Having explored EBM standards and knowledge requirements for health policy decision-making, we present an empirical point of departure for discussing the relationship between EBM and EBP. In a case study exploring the Norwegian Knowledge Centre for the Health Services (NOKC), an independent government unit, we first searched for information about the background and development of the NOKC to establish a research context. We then identified, selected and organized official NOKC publications as an empirical sample of typical top-of-the-line knowledge delivery adhering to EBM standards. Finally, we explored conclusions in this type of publication, specifically addressing their potential as policy decision tools. From a total sample of 151 SRs published by the NOKC in the period 2004-2013, a purposive subsample from 2012 (14 publications) advised major caution about their conclusions because of the quality or relevance of the underlying documentation. Although the case study did not include a systematic investigation of uptake and policy consequences, SRs were found to be inappropriate as universal tools for health policy decision-making. The case study demonstrates that EBM is not necessarily suited to knowledge provision for every kind of policy decision-making. Our analysis raises the question of whether the evidence-based movement, represented here by an independent government organization, undertakes too broad a range of commissions using

Evidence on Adrenaline Use in Resuscitation and Its Relevance to Newborn Infants: A Non-Systematic Review.

Guidelines for newborn resuscitation state that if the heart rate does not increase despite adequate ventilation and chest compressions, adrenaline administration should be considered. However, controversy exists around the safety and effectiveness of adrenaline in newborn resuscitation. The aim of this review was to summarise a selection of the current knowledge about adrenaline during resuscitation and evaluate its relevance to newborn infants. A search in PubMed, Embase, and Google Scholar until September 1, 2015, using search terms including adrenaline/epinephrine, cardiopulmonary resuscitation, death, severe brain injury, necrotizing enterocolitis, bronchopulmonary dysplasia, and adrenaline versus vasopressin/placebo. Adult data indicate that adrenaline improves the return of spontaneous circulation (ROSC) but not survival to hospital discharge. Newborn animal studies reported that adrenaline might be needed to achieve ROSC. Intravenous administration (10-30 μg/kg) is recommended; however, if there is no intravenous access, a higher endotracheal dose (50-100 μg/kg) is needed. The safety and effectiveness of intraosseous adrenaline remain undetermined. Early and frequent dosing does not seem to be beneficial. In fact, negative hemodynamic effects have been observed, especially with doses ≥30 μg/kg intravenously. Little is known about adrenaline in birth asphyxia and in preterm infants, but observations indicate that hemodynamics and neurological outcomes may be impaired by adrenaline administration in these conditions. However, a causal relationship between adrenaline administration and outcomes cannot be established from the few available retrospective studies. Alternative vasoconstrictors have been investigated, but the evidence is scarce. More research is needed on the benefits and risks of adrenaline in asphyxia-induced bradycardia or cardiac arrest during perinatal transition. © 2016 S. Karger AG, Basel.

The translation of research into policy and practice is enhanced by policymakers who can recognise and articulate their information needs and researchers that understand the policymakers' environment. As researchers, we sought to understand the policymaking process and how research evidence may contribute in South Africa and Cameroon. We conducted qualitative in-depth interviews in South Africa and focus group discussions in Cameroon with purposively sampled subnational (provincial and regional) government health programme managers. Audio recorded interviews were transcribed, thematically coded and analysed. Participants in both countries described the complex, often lengthy nature of policymaking processes, which often include back-and-forth consultations with many diverse stakeholder groups. These processes may be influenced by political structures, relationships between national and subnational levels, funding and international stakeholder agendas. Research is not a main driver of policy, but rather current contextual realities, costs, logistics and people (clinicians, NGOs, funders) influence the policy, and research plays a part. Research evidence is frequently perceived as unavailable, inaccessible, ill-timed or not applicable. The reliability of research on the internet was questioned. Evidence-informed health decision-making (EIDM) is regarded as necessary in South Africa but is less well understood in Cameroon. Insufficient time and capacity were hindrances to EIDM in both countries. Good relationships between researchers and policymakers may facilitate EIDM. Researchers should have a good understanding of the policymaking environment if they want to influence it. Greater interaction between policymakers and researchers is perceived as beneficial when formulating research and policy questions as it raises researchers' awareness of implementation challenges and enables the design of tailored and focused strategies to respond to policymakers' needs

“Zebrafishing” for Novel Genes Relevant to the Glomerular Filtration Barrier

Directory of Open Access Journals (Sweden)

Nils Hanke

2013-01-01

Full Text Available Data for genes relevant to glomerular filtration barrier function or proteinuria is continually increasing in an era of microarrays, genome-wide association studies, and quantitative trait locus analysis. Researchers are limited by published literature searches to select the most relevant genes to investigate. High-throughput cell cultures and other in vitro systems ultimately need to demonstrate proof in an in vivo model. Generating mammalian models for the genes of interest is costly and time intensive, and yields only a small number of test subjects. These models also have many pitfalls such as possible embryonic mortality and failure to generate phenotypes or generate nonkidney specific phenotypes. Here we describe an in vivo zebrafish model as a simple vertebrate screening system to identify genes relevant to glomerular filtration barrier function. Using our technology, we are able to screen entirely novel genes in 4–6 weeks in hundreds of live test subjects at a fraction of the cost of a mammalian model. Our system produces consistent and reliable evidence for gene relevance in glomerular kidney disease; the results then provide merit for further analysis in mammalian models.

Physical, psychological, sexual, and systemic abuse of children with disabilities in East Africa: Mapping the evidence.

Science.gov (United States)

Winters, Niall; Langer, Laurenz; Geniets, Anne

2017-01-01

Children with disabilities (CWDs) are at a higher risk of being maltreated than are typical children. The evidence base on the abuse of children with disabilities living in low- and middle-income countries is extremely limited but the problem is particularly acute in East Africa. We don't know the types of evidence that exist on this topic. This problem is compounded by the fact that key indicators of disability, such as reliable prevalence rates, are not available currently. This paper addresses this serious problem by mapping the existing evidence-base to document the coverage, patterns, and gaps in existing research on the abuse of children with disabilities in East Africa. An evidence map, following systematic review guidelines, was conducted and included a systematic search, transparent and structured data extraction, and critical appraisal.

Full Text Available Children with disabilities (CWDs are at a higher risk of being maltreated than are typical children. The evidence base on the abuse of children with disabilities living in low- and middle-income countries is extremely limited but the problem is particularly acute in East Africa. We don't know the types of evidence that exist on this topic. This problem is compounded by the fact that key indicators of disability, such as reliable prevalence rates, are not available currently. This paper addresses this serious problem by mapping the existing evidence-base to document the coverage, patterns, and gaps in existing research on the abuse of children with disabilities in East Africa. An evidence map, following systematic review guidelines, was conducted and included a systematic search, transparent and structured data extraction, and critical appraisal. Health and social science databases (Medline, EMBASE, PsychInfo, Taylor&Francis, Web of Science, and SAGE were systematically searched for relevant studies.

Full Text Available This study investigated the acquisition, interpretation, and utilization of research evidence in the 4-H Youth Development Program from the frame of Social Cognitive Theory. Utilizing Consensual Qualitative Research, we interviewed twenty 4-H faculty, staff, and volunteers from seven states. Results indicated four domains, which covered participants’ definitions of research utilization, their experiences utilizing research, the process of acquiring and distributing research, and barriers and facilitators to research utilization. Participants described research use primarily in terms of improving 4-H programs. They discussed their level of confidence (i.e. self-efficacy in finding and applying research evidence and their beliefs about the outcomes of research utilization (i.e. outcomes expectancy. Participants mentioned such barriers as not knowing where to look for research, lack of time, lack of funding, and difficulty applying research findings to their work. The facilitators included support from other 4-H colleagues and availability of 4-H specific conferences, publications, and curriculum databases.

The goal of the 'Opportunities for Catalysis Research in Carbon Management' workshop was to review within the context of greenhouse gas/carbon issues the current state of knowledge, barriers to further scientific and technological progress, and basic scientific research needs in the areas of H{sub 2} generation and utilization, light hydrocarbon activation and utilization, carbon dioxide activation, utilization, and sequestration, emerging techniques and research directions in relevant catalysis research, and in catalysis for more efficient transportation engines. Several overarching themes emerge from this review. First and foremost, there is a pressing need to better understand in detail the catalytic mechanisms involved in almost every process area mentioned above. This includes the structures, energetics, lifetimes, and reactivities of the species thought to be important in the key catalytic cycles. As much of this type of information as is possible to acquire would also greatly aid in better understanding perplexing, incomplete/inefficient catalytic cycles and in inventing new, efficient ones. The most productive way to attack such problems must include long-term, in-depth fundamental studies of both commercial and model processes, by conventional research techniques and, importantly, by applying various promising new physicochemical and computational approaches which would allow incisive, in situ elucidation of reaction pathways. There is also a consensus that more exploratory experiments, especially high-risk, unconventional catalytic and model studies, should be undertaken. Such an effort will likely require specialized equipment, instrumentation, and computational facilities. The most expeditious and cost-effective means to carry out this research would be by close coupling of academic, industrial, and national laboratory catalysis efforts worldwide. Completely new research approaches should be vigorously explored, ranging from novel compositions

Establishing and promoting connections between health researchers and health professional clinicians may help translate research evidence to clinical practice. Social media may have the capacity to enhance these connections. The aim of this study was to explore health researchers' and clinicians' current use of social media and their beliefs and attitudes towards the use of social media for communicating research evidence. This study used a mixed-methods approach to obtain qualitative and quantitative data. Participation was open to health researchers and clinicians. Data regarding demographic details, current use of social media, and beliefs and attitudes towards the use of social media for professional purposes were obtained through an anonymous Web-based survey. The survey was distributed via email to research centers, educational and clinical institutions, and health professional associations in Australia, India, and Malaysia. Consenting participants were stratified by country and role and selected at random for semistructured telephone interviews to explore themes arising from the survey. A total of 856 participants completed the questionnaire with 125 participants declining to participate, resulting in a response rate of 87.3%. 69 interviews were conducted with participants from Australia, India, and Malaysia. Social media was used for recreation by 89.2% (749/840) of participants and for professional purposes by 80.0% (682/852) of participants. Significant associations were found between frequency of professional social media use and age, gender, country of residence, and graduate status. Over a quarter (26.9%, 229/852) of participants used social media for obtaining research evidence, and 15.0% (128/852) of participants used social media for disseminating research evidence. Most participants (95.9%, 810/845) felt there was a role for social media in disseminating or obtaining research evidence. Over half of the participants (449/842, 53.3%) felt they had a

Evidence-informed health policy 4 – Case descriptions of organizations that support the use of research evidence

2008-12-01

Full Text Available Abstract Background Previous efforts to produce case descriptions have typically not focused on the organizations that produce research evidence and support its use. External evaluations of such organizations have typically not been analyzed as a group to identify the lessons that have emerged across multiple evaluations. Case descriptions offer the potential for capturing the views and experiences of many individuals who are familiar with an organization, including staff, advocates, and critics. Methods We purposively sampled a subgroup of organizations from among those that participated in the second (interview phase of the study and (once from among other organizations with which we were familiar. We developed and pilot-tested a case description data collection protocol, and conducted site visits that included both interviews and documentary analyses. Themes were identified from among responses to semi-structured questions using a constant comparative method of analysis. We produced both a brief (one to two pages written description and a video documentary for each case. Results We conducted 51 interviews as part of the eight site visits. Two organizational strengths were repeatedly cited by individuals participating in the site visits: use of an evidence-based approach (which was identified as being very time-consuming and existence of a strong relationship between researchers and policymakers (which can be challenged by conflicts of interest. Two organizational weaknesses – a lack of resources and the presence of conflicts of interest – were repeatedly cited by individuals participating in the site visits. Participants offered two main suggestions for the World Health Organization (and other international organizations and networks: 1 mobilize one or more of government support, financial resources, and the participation of both policymakers and researchers; and 2 create knowledge-related global public goods.

THE EFFECT OF DERIVATIVE FINANCIAL INSTRUMENTS ON BANK RISKS, RELEVANCE AND FAITHFUL REPRESENTATION: EVIDENCE FROM BANKS IN HUNGARY

Directory of Open Access Journals (Sweden)

Toth Kornel

2014-07-01

Full Text Available In a continuously changing business environment accounting data have to provide useful information in order to achieve relevant and faithful representation in financial statements. Since global markets have changed radically, growing international trade means the horizons of investors and borrowers have now become global, which has increased the level of their risks. Concerning international trade and investment, one of the most important risks is uncertainty about future foreign currency exchange rates and interest rates. Changes in financial markets have increased the use of derivative instruments (such as forwards, futures, swaps, and options to hedge risk exposure worldwide, while the related accounting standards have not kept pace with those changes. Because of the complexity and variety of these instruments, reporting on derivatives faces many difficulties, since a different framework and different accounting concepts are required to present useful financial information. For these reasons the growing use of derivative financial instruments and the challenges of the global financial system have intensified and sharpened debates about whether derivative instruments increase or decrease the risk of banks, affecting faithful representation based on their financial statements and decision usefulness of the reported information. This study aims to describe the transformation of accounting concepts and its effect on fair value accounting for derivative financial instruments in the information economy. The research question of the paper is whether the advantages of fair value accounting exceed the disadvantages, especially in the case of derivatives, in reducing the uncertainty and risk associated with financial reporting. Based on this question, the purpose of the empirical research is to assess the level of different risks which banks operating in Hungary face when using derivative financial instruments and to investigate how and to what extent

Recent efforts have been devoted to understanding the conditions by which research evidence use (REU) is facilitated from the perspective of system leaders in the context of implementing evidence-based child mental health interventions. However, we have limited understanding of the extent to which outer contextual factors influence REU. Outer contextual factors for 37 counties in California were gathered from public records in 2008; and child welfare, juvenile justice, and mental health system leaders' perceptions of their REU were measured via a web-based survey from 2010 to 2012. Results showed that leaders with higher educational attainment and in counties with lower expenditures on inpatient mental health services were significantly associated with higher REU. Positive relationships between gathering research evidence and racial minority concentration and poverty at the county level were also detected. Results underscore the need to identify the organizational and socio-political factors by which mental health services and resources meet client demands that influence REU, and to recruit and retain providers with a graduate degree to negotiate work demands and interpret research evidence.

To describe the methodology used by the Reassessment Campaign on Veterinary Resuscitation (RECOVER) to evaluate the scientific evidence relevant to small animal CPR and to compose consensus-based clinical CPR guidelines for dogs and cats. This report is part of a series of 7 articles on the RECOVER evidence and knowledge gap analysis and consensus-based small animal CPR guidelines. It describes the organizational structure of RECOVER, the evaluation process employed, consisting of standardized literature searches, the analysis of relevant articles according to study design, species and predefined quality markers, and the drafting of clinical CPR guidelines based on these data. Therefore, this article serves as the methodology section for the subsequent 6 RECOVER articles. Academia, referral practice. RECOVER is a collaborative initiative that systematically evaluated the evidence on 74 topics relevant to small animal CPR and generated 101 clinical CPR guidelines from this analysis. All primary contributors were veterinary specialists, approximately evenly split between academic institutions and private referral practices. The evidence evaluation and guideline drafting processes were conducted according to a predefined sequence of steps designed to reduce bias and increase the repeatability of the findings, including multiple levels of review, culminating in a consensus process. Many knowledge gaps were identified that will allow prioritization of research efforts in veterinary CPR. Collaborative systematic evidence review is organizationally challenging but feasible and effective in veterinary medicine. More experience is needed to refine the process. © Veterinary Emergency and Critical Care Society 2012.

Full Text Available Abstract Background The ultimate goal of knowledge translation and exchange (KTE activities is to facilitate incorporation of research knowledge into program and policy development decision making. Evidence-informed decision making involves translation of the best available evidence from a systematically collected, appraised, and analyzed body of knowledge. Knowledge management (KM is emerging as a key factor contributing to the realization of evidence-informed public health decision making. The goal of health-evidence.ca is to promote evidence-informed public health decision making through facilitation of decision maker access to, retrieval, and use of the best available synthesized research evidence evaluating the effectiveness of public health interventions. Methods The systematic reviews that populate health evidence.ca are identified through an extensive search (1985-present of 7 electronic databases: MEDLINE, EMBASE, CINAHL, PsycINFO, Sociological Abstracts, BIOSIS, and SportDiscus; handsearching of over 20 journals; and reference list searches of all relevant reviews. Reviews are assessed for relevance and quality by two independent reviewers. Commonly-used public health terms are used to assign key words to each review, and project staff members compose short summaries highlighting results and implications for policy and practice. Results As of June 2010, there are 1913 reviews in the health-evidence.ca registry in 21 public health and health promotion topic areas. Of these, 78% have been assessed as being of strong or moderate methodological quality. Health-evidence.ca receives approximately 35,000 visits per year, 20,596 of which are unique visitors, representing approximately 100 visits per day. Just under half of all visitors return to the site, with the average user spending six minutes and visiting seven pages per visit.

Evidence maps are a method of systematically characterising the range of research activity in broad topic areas and are a tool for guiding research priorities. 'Evidence-mapping' methodology was used to quantify the nature and distribution of recent peer-reviewed research into the mental health and wellbeing of Australian emergency services personnel. A search of the PsycINFO, EMBASE and Cochrane Library databases was performed for primary research articles that were published between January 2011 and July 2016. In all, 43 studies of primary research were identified and mapped. The majority of the research focused on organisational and individual/social factors and how they relate to mental health problems/wellbeing. There were several areas of research where very few studies were detected through the mapping process, including suicide, personality, stigma and pre-employment factors that may contribute to mental health outcomes and the use of e-health. No studies were detected which examined the prevalence of self-harm and/or harm to others, bullying, alcohol/substance use, barriers to care or experience of families of emergency services personnel. In addition, there was no comprehensive national study that had investigated all sectors of emergency services personnel. This evidence map highlights the need for future research to address the current gaps in mental health and wellbeing research among Australian emergency services personnel. Improved understanding of the mental health and wellbeing of emergency services personnel, and the factors that contribute, should guide organisations' wellbeing policies and procedures.

No studies have sought to provide a quantitative or qualitative critique of research in the field of neurointerventional surgery. To analyze recent publications from the Journal of Neurointerventional Surgery ( JNIS ) to test a new method for assessing research and collaboration. We reviewed all JNIS Online First publications from 25 February 2015 to 24 February 2016. All publications-human or non-human research, systematic reviews, meta-analyses, or literature reviews-were included; editorials and commentaries were excluded. For each publication, study design, number of patients, authors, contributing centers, and study subject were recorded. Level of evidence was defined using a new scale. A total of 206 articles met inclusion criteria. Only 4% were prospective studies. Twenty-eight per cent of scientific research featured patient series of nine or less. The majority of publications were categorized as low-level evidence (91%). Forty-seven per cent involved individuals from a single center, with 87% having collaboration from three or fewer centers. International collaboration was present in 19%. While 256 institutions from 31 countries were represented, 66% were represented in only one publication. We queried JNIS Online First articles from a 1-year period in a pilot study to test a new method of analyzing research quality and collaboration. The methodology appears to adequately quantify the studies into evidence tiers that emulate previously published, widely accepted scales. This may be useful for future comparison of peer-reviewed journals or for studying the quality of research being performed in different disease processes or medical specialties.

Separation systems such as gas chromatography, high performance liquid chromatography, capillary electromigration, and supercritical fluid chromatography, all coupled to mass spectrometry, are discussed. Typical applications are reviewed for relevant chiral analytes such as amphetamines and amphetamine-derived designer drugs, methadone, tramadol, psychotropic and other CNS acting drugs, anticoagulants, cardiovascular drugs, and some other drugs. Usefulness of chiral drug analysis in the interpretation of analytical results in clinical and forensic toxicology is discussed as well. Copyright © 2012 Elsevier B.V. All rights reserved.

Shifting from policy relevance to policy translation: do housing and neighborhoods affect children's mental health?

Science.gov (United States)

Osypuk, Theresa L

2015-02-01

The impact of housing and neighborhood context on children's mental health, as addressed by Flouri et al. (Soc Psychiatry Psychiatr Epidemiol, 2014), is an important, understudied topic in social epidemiology. Although the vast majority of this body of research has been descriptive, generating translational research is essential. This article offers guidance on interpreting evidence from observational studies for translation into policy, related to three policy-relevant elements of housing: receipt of affordable housing subsidies, the target population to which results generalize, and operationalization and modeling of neighborhood context. Policy translation is imperative for understanding which levers outside the health sector can be manipulated to change fundamental causes of mental health related to housing and neighborhood. Shifting from policy relevance to policy translation may be challenging, especially for understanding social causation in observational studies, but it is a necessary shift for improving population health.

Frith, James; Bashir, Ayat S; Elliott, Chris S; Newton, Julia L

2014-11-01

With a rapidly expanding older population and increased survival of older people with chronic disease, we can expect to see increasing numbers of people with orthostatic hypotension (OH). Unfortunately the evidence base for people with OH, with particular relevance to older people, has not kept up and has resulted in a real lack of progress and little good evidence. There are several areas of research that could potentially benefit patients but establishing which ones are priority areas requires public and patient involvement (PPI). This process includes people/patients in the research team to maximise the relevance, success and translation of the research. This brief report describes the early involvement of older people in prioritising the research question, methods to improve adherence during a trial and the preferred methods to disseminate research output. The individuals' priority was to research non-pharmacological treatment strategies and to improve the education of patients about their condition. Education was felt to be the best strategy to promote adherence during a trial, with change in symptoms and quality of life felt to be the most important outcome measures as opposed to blood pressure. This report offers guidance for academics that are undertaking OH-related research and how they can improve its relevance and increase its translation into clinical practice. © The Author 2014.

Full Text Available Evidence-Based Dentistry (EBD is a systematic approach for ob-taining the best available clini-cally relevant scientific evidence with the ultimate goal and intent of increasing effectiveness and efficacy in clinical decision-making. EBD pursues optimizing both the patient’s benefit through the best utilization of dentist’s experience and clinical expertise, and on making full use of the most reliable and va-lid research outcomes. EBD is initiated by the patient-dentist interaction, which is translated into a patient-centered P.I.C.O. question. The resulting literature bibliome is assessed and quantified for the level and quality of the evidence by means of fully validated and reli-able instruments based on common standard criteria of research methodology, design and statistical analysis. The outcomes are evaluated by acceptable sampling analysis, Such that studies, whose flaws have been identified to result potentially into misleading infor-mation to the patients and/or practitioner may be judiciously removed from further consideration". The research synthesis process tests for overarching statistical sig-nificance among non-heterogeneous outcomes, and yields a consensus of the best available evidence. The systematic nature of the re-search review and synthesis that characterizes EBD is reported in the literature as “systematic reviews”, “complex systematic reviews”, or “clinically relevant complex systematic reviews”. Thus the reported best available evidence ensures patient-centered clinical decision for interventions of the highest possible effectiveness and effi-cacy. EBD contrasts with traditional dentistry based on the evidence for its systematic stringency, coupled with its fundamental validity as a patient-centered optimization of clinical modes of interventions.

The science of searching--how to find the evidence quickly and efficiently.

LENUS (Irish Health Repository)

Wallace, J

2012-04-01

One of the most common findings from health research is the failure to routinely translate research evidence into daily practice. Studies simply can\\'t guarantee the use of their findings. There is just too much research to keep track of and so a large gap develops between what is known and what is done. Evidence that should change practice is often ignored for years. The literature is constantly changing and when an answer to a clinical question is sought, it often comes from an out-of-date textbook. Remaining knowledgeable of current, relevant research is difficult. Consequently, the development of skills in searching electronic databases is vital for the up-to-date clinician.

Recognizing the need for evidence to inform public health officials and health care workers in the U.S. government and low- and middle-income country governments on efficient, effective behavior change policies, strategies, and programs for child health and development, the U.S. government convened the Evidence Summit on Enhancing Child Survival and Development in Lower- and Middle-Income Countries by Achieving Population-Level Behavior Change. This article summarizes the background and methods for the acquisition and evaluation of the evidence used to the achieve the goals of the summit that is reviewed in other articles in this special issue of the Journal of Health Communication. The process began by identifying focal questions intended to inform the U.S. and low- and middle-income governments about behavior change interventions that accelerate reductions in under-5 mortality and optimize healthy and protective child development to 5 years of age. Experts were selected representing the research and program communities, academia, relevant nongovernmental organizations, and government agencies and assembled into evidence review teams. This was followed by the systematic gathering of relevant peer-reviewed literature that would inform the focal questions. Members of the evidence review teams were invited to add relevant articles not identified in the initial literature review to complete the bibliographies. Details of the search processes and methods used for screening and quality reviews are described.

Full Text Available Introduction: Comparative effectiveness and efficacy research for analysis and practice (CEERAP was performed to assess the effects of penicillin-based versus erythromycin-based antibiotic treatments in patients with skin and soft tissue infections (SSTIs including cellulitis, impetigo, and erysipelas. Because SSTIs, especially orofacial cellulitis, are volatile infectious diseases of a life-threatening nature, research on the most efficacious remedies is necessary. Methods: The stringent bibliome yielded three systematic reviews, which were examined for quality of research synthesis protocol and clinical relevance. Results: The sample size of three, rendered the statistical analyses and cumulative meta-analysis problematic. Conclusion: The systematic review outlined here should aid in increasing clinical awareness, improving patient health literacy, and promoting consensus of the best evidence base (BEB to mitigate the threat of sepsis and potential death caused by cellulitis infections.

Evidence-based policymaking is not like evidence-based medicine, so how far should you go to bridge the divide between evidence and policy?

There is extensive health and public health literature on the 'evidence-policy gap', exploring the frustrating experiences of scientists trying to secure a response to the problems and solutions they raise and identifying the need for better evidence to reduce policymaker uncertainty. We offer a new perspective by using policy theory to propose research with greater impact, identifying the need to use persuasion to reduce ambiguity, and to adapt to multi-level policymaking systems.We identify insights from secondary data, namely systematic reviews, critical analysis and policy theories relevant to evidence-based policymaking. The studies are drawn primarily from countries such as the United States, United Kingdom, Canada, Australia and New Zealand. We combine empirical and normative elements to identify the ways in which scientists can, do and could influence policy.We identify two important dilemmas, for scientists and researchers, that arise from our initial advice. First, effective actors combine evidence with manipulative emotional appeals to influence the policy agenda - should scientists do the same, or would the reputational costs outweigh the policy benefits? Second, when adapting to multi-level policymaking, should scientists prioritise 'evidence-based' policymaking above other factors? The latter includes governance principles such the 'co-production' of policy between local public bodies, interest groups and service users. This process may be based primarily on values and involve actors with no commitment to a hierarchy of evidence.We conclude that successful engagement in 'evidence-based policymaking' requires pragmatism, combining scientific evidence with governance principles, and persuasion to translate complex evidence into simple stories. To maximise the use of scientific evidence in health and public health policy, researchers should recognise the tendency of policymakers to base judgements on their beliefs, and shortcuts based on their emotions

Stoltz, Peter; Skärsäter, Ingela; Willman, Ania

2009-01-01

This article reports on commissioned research funded by the Swedish Council of Technology Assessment in Health Care (SBU) and the Swedish Nursing Society (SSF). The objective was to review computer-based education programs. However, as the review produced insufficient evidence of effectiveness, the publication was withheld due to a previous incident where such evidence was misunderstood by Swedish policy and health care decision makers. This article highlights the concept of evidence with regard to the consequences of insufficient evidence of effectiveness being mistaken for evidence of no effectiveness. The aim is also to present a systematic review evaluating a computer-based education program for patients suffering from severe mental illness. Systematic database searches in Medline, CINAHL, PsycINFO and the Cochrane Library identified a total of 131 potentially relevant references. Thereafter, 27 references were retrieved as full-text documents, of which 5 were finally included and co-reviewed by two independent researchers. The review found no decisive evidence of effectiveness regarding computer-based education programs designed to assist persons suffering from severe mental illness. Failing to see the difference between insufficient evidence and evidence of no effectiveness may have unexpected consequences. As a result, practice may be misguided and treatments withheld, which at worse may have harmful consequences for patients. In the end, it is of utmost importance that researchers do good quality research by ensuring statistical power and quality of outcome measurement. For example, this review of computer-based education programs could have revealed effective ways of dealing with severe mental illness if the studies included had been conducted using more sophisticated designs.

Synthesizing Econometric Evidence: The Case of Demand Elasticity Estimates.

Science.gov (United States)

DeCicca, Philip; Kenkel, Don

2015-06-01

Econometric estimates of the responsiveness of health-related consumer demand to higher prices are often key ingredients for risk policy analysis. We review the potential advantages and challenges of synthesizing econometric evidence on the price-responsiveness of consumer demand. We draw on examples of research on consumer demand for health-related goods, especially cigarettes. We argue that the overarching goal of research synthesis in this context is to provide policy-relevant evidence for broad-brush conclusions. We propose three main criteria to select among research synthesis methods. We discuss how in principle and in current practice synthesis of research on the price-elasticity of smoking meets our proposed criteria. Our analysis of current practice also contributes to academic research on the specific policy question of the effectiveness of higher cigarette prices to reduce smoking. Although we point out challenges and limitations, we believe more work on research synthesis in this area will be productive and important. © 2015 Society for Risk Analysis.

Increasing the use of evidence in policy making means strengthening capacity on both the supply and demand sides of evidence production. However, little experience of strengthening the capacity of policy makers in low- and middle- income countries has been published to date. We describe the experiences of five projects (in Bangladesh, Gambia, India and Nigeria), where collaborative teams of researchers and policy makers/policy influencers worked to strengthen policy maker capacity to increase the use of evidence in policy. Activities were focused on three (interlinked) levels of capacity building: individual, organizational and, occasionally, institutional. Interventions included increasing access to research/data, promoting frequent interactions between researchers and members of the policy communities, and increasing the receptivity towards research/data in policy making or policy-implementing organizations. Teams were successful in building the capacity of individuals to access, understand and use evidence/data. Strengthening organizational capacity generally involved support to infrastructure (e.g. through information technology resources) and was also deemed to be successful. There was less appetite to address the need to strengthen institutional capacity—although this was acknowledged to be fundamental to promoting sustainable use of evidence, it was also recognized as requiring resources, legitimacy and regulatory support from policy makers. Evaluation across the three spheres of capacity building was made more challenging by the lack of agreed upon evaluation frameworks. In this article, we propose a new framework for assessing the impact of capacity strengthening activities to promote the use of evidence/data in policy making. Our evaluation concluded that strengthening the capacity of individuals and organizations is an important but likely insufficient step in ensuring the use of evidence/data in policy-cycles.

Full Text Available Abstract The complex evidence-policy interface in low and middle income country settings is receiving increasing attention. Future Health Systems (FHS: Innovations for Equity, is a research consortium conducting health systems explorations in six Asian and African countries: Bangladesh, India, China, Afghanistan, Uganda, and Nigeria. The cross-country research consortium provides a unique opportunity to explore the research-policy interface. Three key activities were undertaken during the initial phase of this five-year project. First, key considerations in strengthening evidence-policy linkages in health system research were developed by FHS researchers through workshops and electronic communications. Four key considerations in strengthening evidence-policy linkages are postulated: development context; research characteristics; decision-making processes; and stakeholder engagement. Second, these four considerations were applied to research proposals in each of the six countries to highlight features in the research plans that potentially strengthen the research-policy interface and opportunities for improvement. Finally, the utility of the approach for setting research priorities in health policy and systems research was reflected upon. These three activities yielded interesting findings. First, developmental consideration with four dimensions – poverty, vulnerabilities, capabilities, and health shocks – provides an entry point in examining research-policy interfaces in the six settings. Second, research plans focused upon on the ground realities in specific countries strengthens the interface. Third, focusing on research prioritized by decision-makers, within a politicized health arena, enhances chances of research influencing action. Lastly, early and continued engagement of multiple stakeholders, from local to national levels, is conducive to enhanced communication at the interface. The approach described has four main utilities: first

The evidence-policy divide: a 'critical computational linguistics' approach to the language of 18 health agency CEOs from 9 countries.

Bell, Erica; Seidel, Bastian M

2012-10-30

There is an emerging body of literature suggesting that the evidence-practice divide in health policy is complex and multi-factorial but less is known about the processes by which health policy-makers use evidence and their views about the specific features of useful evidence. This study aimed to contribute to understandings of how the most influential health policy-makers view useful evidence, in ways that help explore and question how the evidence-policy divide is understood and what research might be supported to help overcome this divide. A purposeful sample of 18 national and state health agency CEOs from 9 countries was obtained. Participants were interviewed using open-ended questions that asked them to define specific features of useful evidence. The analysis involved two main approaches 1)quantitative mapping of interview transcripts using Bayesian-based computational linguistics software 2)qualitative critical discourse analysis to explore the nuances of language extracts so identified. The decision-making, conclusions-oriented world of policy-making is constructed separately, but not exclusively, by policy-makers from the world of research. Research is not so much devalued by them as described as too technical- yet at the same time not methodologically complex enough to engage with localised policy-making contexts. It is not that policy-makers are negative about academics or universities, it is that they struggle to find complexity-oriented methodologies for understanding their stakeholder communities and improving systems. They did not describe themselves as having a more positive role in solving this challenge than academics. These interviews do not support simplistic definitions of policy-makers and researchers as coming from two irreconcilable worlds. They suggest that qualitative and quantitative research is valued by policy-makers but that to be policy-relevant health research may need to focus on building complexity-oriented research methods for

Approach Towards an Evidence-Oriented Knowledge and Data Acquisition for the Optimization of Interdisciplinary Care in Dentistry and General Medicine.

Seitz, Max W; Haux, Christian; Knaup, Petra; Schubert, Ingrid; Listl, Stefan

2018-01-01

Associations between dental and chronic-systemic diseases were observed frequently in medical research, however the findings of this research have so far found little relevance in everyday clinical treatment. Major problems are the assessment of evidence for correlations between such diseases and how to integrate current medical knowledge into the intersectoral care of dentists and general practitioners. On the example of dental and chronic-systemic diseases, the Dent@Prevent project develops an interdisciplinary decision support system (DSS), which provides the specialists with information relevant for the treatment of such cases. To provide the physicians with relevant medical knowledge, a mixed-methods approach is developed to acquire the knowledge in an evidence-oriented way. This procedure includes a literature review, routine data analyses, focus groups of dentists and general practitioners as well as the identification and integration of applicable guidelines and Patient Reported Measures (PRMs) into the treatment process. The developed mixed methods approach for an evidence-oriented knowledge acquisition indicates to be applicable and supportable for interdisciplinary projects. It can raise the systematic quality of the knowledge-acquisition process and can be applicable for an evidence-based system development. Further research is necessary to assess the impact on patient care and to evaluate possible applicability in other interdisciplinary areas.

2018-05-30

Use of research evidence in public health decision making can be affected by organizational supports. Study objectives are to identify patterns of organizational supports and explore associations with research evidence use for job tasks among public health practitioners. In this longitudinal study, we used latent class analysis to identify organizational support patterns, followed by mixed logistic regression analysis to quantify associations with research evidence use. The setting included 12 state public health department chronic disease prevention units and their external partnering organizations involved in chronic disease prevention. Chronic disease prevention staff from 12 US state public health departments and partnering organizations completed self-report surveys at 2 time points, in 2014 and 2016 (N = 872). Latent class analysis was employed to identify subgroups of survey participants with distinct patterns of perceived organizational supports. Two classify-analyze approaches (maximum probability assignment and multiple pseudo-class draws) were used in 2017 to investigate the association between latent class membership and research evidence use. The optimal model identified 4 latent classes, labeled as "unsupportive workplace," "low agency leadership support," "high agency leadership support," and "supportive workplace." With maximum probability assignment, participants in "high agency leadership support" (odds ratio = 2.08; 95% CI, 1.35-3.23) and "supportive workplace" (odds ratio = 1.74; 95% CI, 1.10-2.74) were more likely to use research evidence in job tasks than "unsupportive workplace." The multiple pseudo-class draws produced comparable results with odds ratio = 2.09 (95% CI, 1.31-3.30) for "high agency leadership support" and odds ratio = 1.74 (95% CI, 1.07-2.82) for "supportive workplace." Findings suggest that leadership support may be a crucial element of organizational supports to encourage research evidence use. Organizational supports such

How is nostalgia positioned among self-relevant emotions? We tested, in six studies, which self-relevant emotions are perceived as most similar versus least similar to nostalgia, and what underlies these similarities/differences. We used multidimensional scaling to chart the perceived similarities/differences among self-relevant emotions, resulting in two-dimensional models. The results were revealing. Nostalgia is positioned among self-relevant emotions characterised by positive valence, an approach orientation, and low arousal. Nostalgia most resembles pride and self-compassion, and least resembles embarrassment and shame. Our research pioneered the integration of nostalgia among self-relevant emotions.

'Communicate to vaccinate' (COMMVAC. building evidence for improving communication about childhood vaccinations in low- and middle-income countries: protocol for a programme of research

Directory of Open Access Journals (Sweden)

Lewin Simon

2011-12-01

Full Text Available Abstract Background Effective provider-parent communication can improve childhood vaccination uptake and strengthen immunisation services in low- and middle-income countries (LMICs. Building capacity to improve communication strategies has been neglected. Rigorous research exists but is not readily found or applicable to LMICs, making it difficult for policy makers to use it to inform vaccination policies and practice. The aim of this project is to build research knowledge and capacity to use evidence-based strategies for improving communication about childhood vaccinations with parents and communities in LMICs. Methods and design This project is a mixed methods study with six sub-studies. In sub-study one, we will develop a systematic map of provider-parent communication interventions for childhood vaccinations by screening and extracting data from relevant literature. This map will inform sub-study two, in which we will develop a taxonomy of interventions to improve provider-parent communication around childhood vaccination. In sub-study three, the taxonomy will be populated with trial citations to create an evidence map, which will also identify how evidence is linked to communication barriers regarding vaccination. In the project's fourth sub-study, we will present the interventions map, taxonomy, and evidence map to international stakeholders to identify high-priority topics for systematic reviews of interventions to improve parent-provider communication for childhood vaccination. We will produce systematic reviews of the effects of high-priority interventions in the fifth sub-study. In the sixth and final sub-study of the project, evidence from the systematic reviews will be translated into accessible formats and messages for dissemination to LMICs. Discussion This project combines evidence mapping, conceptual and taxonomy development, priority setting, systematic reviews, and knowledge transfer. It will build and share concepts, terms

2009-03-01

Full Text Available Abstract Background Organizational leaders in business and medicine have been experiencing a similar dilemma: how to ensure that their organizational members are adopting work innovations in a timely fashion. Organizational leaders in healthcare have attempted to resolve this dilemma by offering specific solutions, such as evidence-based medicine (EBM, but organizations are still not systematically adopting evidence-based practice innovations as rapidly as expected by policy-makers (the knowing-doing gap problem. Some business leaders have adopted a systems-based perspective, called the learning organization (LO, to address a similar dilemma. Three years ago, the Society of General Internal Medicine's Evidence-based Medicine Task Force began an inquiry to integrate the EBM and LO concepts into one model to address the knowing-doing gap problem. Methods During the model development process, the authors searched several databases for relevant LO frameworks and their related concepts by using a broad search strategy. To identify the key LO frameworks and consolidate them into one model, the authors used consensus-based decision-making and a narrative thematic synthesis guided by several qualitative criteria. The authors subjected the model to external, independent review and improved upon its design with this feedback. Results The authors found seven LO frameworks particularly relevant to evidence-based practice innovations in organizations. The authors describe their interpretations of these frameworks for healthcare organizations, the process they used to integrate the LO frameworks with EBM principles, and the resulting Evidence in the Learning Organization (ELO model. They also provide a health organization scenario to illustrate ELO concepts in application. Conclusion The authors intend, by sharing the LO frameworks and the ELO model, to help organizations identify their capacities to learn and share knowledge about evidence-based practice

Full Text Available Sven BraeutigamOxford Centre for Human Brain Activity, University of Oxford, Oxford, United KingdomAbstract: For about a hundred years, theorists and traders alike have tried to unravel and understand the mechanisms and hidden rules underlying and perhaps determining economically relevant behavior. This review focuses on recent developments in neuroeconomics, where the emphasis is placed on two directions of research: first, research exploiting common experiences of urban inhabitants in industrialized societies to provide experimental paradigms with a broader real-life content; second, research based on behavioral genetics, which provides an additional dimension for experimental control and manipulation. In addition, possible limitations of state-of-the-art neuroeconomics research are addressed. It is argued that observations of neuronal systems involved in economic behavior converge to some extent across the technologies and paradigms used. Conceptually, the data available as of today raise the possibility that neuroeconomic research might provide evidence at the neuronal level for the existence of multiple systems of thought and for the importance of conflict. Methodologically, Bayesian approaches in particular may play an important role in identifying mechanisms and establishing causality between patterns of neural activity and economic behavior.Keywords: neuroeconomics, behavioral genetics, decision-making, consumer behavior, neural system

Shifting from policy relevance to policy translation: Do housing and neighborhoods affect children’s mental health?

Science.gov (United States)

Osypuk, Theresa L.

2016-01-01

The impact of housing and neighborhood context on children’s mental health, as addressed by Flouri and colleagues [1], is an important, understudied topic in social epidemiology. Although the vast majority of this body of research has been descriptive, generating translational research is essential. This article offers guidance on interpreting evidence from observational studies for translation into policy, related to three policy-relevant elements of housing: receipt of affordable housing subsidies, the target population to which results generalize, and operationalization and modeling of neighborhood context. Policy translation is imperative for understanding which levers outside the health sector can be manipulated to change fundamental causes of mental health related to housing and neighborhood. Shifting from policy relevance to policy translation may be challenging, especially for understanding social causation in observational studies, but it’s a necessary shift for improving population health.

Full Text Available Objective ‐ To examine the similarities and differences between research questions asked by librarians in 2001 to those posed in 2006, and to explore to what extent the published research supports the questions being asked.Methods ‐ Questions collected in 2001 by members of the Evidence‐Based Librarianship Implementation Committee (EBLIC of the MLA Research Section were compared with questions collected in 2006 at a cross‐sectoral seminar introducing evidence based library and information practice to Australian librarians. Questions from each list were categorized using the domains of librarianship proposed by Crumley and Koufogiannakis in 2001, and examined with reference to a content analysis of the library and information studies (LIS research published in 2001 by Koufogiannakis, Slater, and Crumley in 2004.Results ‐ In 2001 and 2006 the most commonly asked questions were in the domain of management (29%, 33%, followed by education (24%, 18.5%. In 2001 questions in the marketing/promotion category ranked lowest (1%, however representation was much greater in 2006 (18.5% ranking an equal second with education.

Koufogiannakis, Slater, and Crumley’s content analysis of LIS research published in 2001 revealed that the most popular domain for research was information access and retrieval (38% followed by collections (24%. Only 1% of published LIS research (seven articles was in the domain of marketing/promotion. In contrast, 36 articles originally assigned to one of the six established domains could more appropriately have been included in a proposed new domain of professional issues.Conclusion ‐ The disparity between questions being asked by practitioners and the evidence being generated by researchers suggests that the research‐practice gap is still an issue.

The gap between research and practice or policy is often described as a problem. To identify new barriers of and facilitators to the use of evidence by policymakers, and assess the state of research in this area, we updated a systematic review. Systematic review. We searched online databases including Medline, Embase, SocSci Abstracts, CDS, DARE, Psychlit, Cochrane Library, NHSEED, HTA, PAIS, IBSS (Search dates: July 2000 - September 2012). Studies were included if they were primary research or systematic reviews about factors affecting the use of evidence in policy. Studies were coded to extract data on methods, topic, focus, results and population. 145 new studies were identified, of which over half were published after 2010. Thirteen systematic reviews were included. Compared with the original review, a much wider range of policy topics was found. Although still primarily in the health field, studies were also drawn from criminal justice, traffic policy, drug policy, and partnership working. The most frequently reported barriers to evidence uptake were poor access to good quality relevant research, and lack of timely research output. The most frequently reported facilitators were collaboration between researchers and policymakers, and improved relationships and skills. There is an increasing amount of research into new models of knowledge transfer, and evaluations of interventions such as knowledge brokerage. Timely access to good quality and relevant research evidence, collaborations with policymakers and relationship- and skills-building with policymakers are reported to be the most important factors in influencing the use of evidence. Although investigations into the use of evidence have spread beyond the health field and into more countries, the main barriers and facilitators remained the same as in the earlier review. Few studies provide clear definitions of policy, evidence or policymaker. Nor are empirical data about policy processes or implementation of

Milat, Andrew J; Li, Ben

2017-02-15

A significant challenge in research translation is that interested parties interpret and apply the associated terms and conceptual frameworks in different ways. The purpose of this review was to: a) examine different research translation frameworks; b) examine the similarities and differences between the frameworks; and c) identify key strengths and weaknesses of the models when they are applied in practice. The review involved a keyword search of PubMed. The search string was (translational research OR knowledge translation OR evidence to practice) AND (framework OR model OR theory) AND (public health OR health promotion OR medicine). Included studies were published in English between January 1990 and December 2014, and described frameworks, models or theories associated with research translation. The final review included 98 papers, and 41 different frameworks and models were identified. The most frequently applied knowledge translation framework in the literature was RE-AIM, followed by the knowledge translation continuum or 'T' models, the Knowledge to Action framework, the PARiHS framework, evidence based public health models, and the stages of research and evaluation model. The models identified in this review stem from different fields, including implementation science, basic and medical sciences, health services research and public health, and propose different but related pathways to closing the research-practice gap.

Collectivism and coping: current theories, evidence, and measurements of collective coping.

Science.gov (United States)

Kuo, Ben C H

2013-01-01

A burgeoning body of cultural coping research has begun to identify the prevalence and the functional importance of collective coping behaviors among culturally diverse populations in North America and internationally. These emerging findings are highly significant as they evidence culture's impacts on the stress-coping process via collectivistic values and orientation. They provide a critical counterpoint to the prevailing Western, individualistic stress and coping paradigm. However, current research and understanding about collective coping appear to be piecemeal and not well integrated. To address this issue, this review attempts to comprehensively survey, summarize, and evaluate existing research related to collective coping and its implications for coping research with culturally diverse populations from multiple domains. Specifically, this paper reviews relevant research and knowledge on collective coping in terms of: (a) operational definitions; (b) theories; (c) empirical evidence based on studies of specific cultural groups and broad cultural values/dimensions; (d) measurements; and (e) implications for future cultural coping research. Overall, collective coping behaviors are conceived as a product of the communal/relational norms and values of a cultural group across studies. They also encompass a wide array of stress responses ranging from value-driven to interpersonally based to culturally conditioned emotional/cognitive to religion- and spirituality-grounded coping strategies. In addition, this review highlights: (a) the relevance and the potential of cultural coping theories to guide future collective coping research; (b) growing evidence for the prominence of collective coping behaviors particularly among Asian nationals, Asian Americans/Canadians and African Americans/Canadians; (c) preference for collective coping behaviors as a function of collectivism and interdependent cultural value and orientation; and (d) six cultural coping scales.

2008-10-01

The purpose of this article is to provide an evidence-based synthesis of the research literature on music intervention for agitated behavior in Alzheimer's dementia. A qualitative review of the literature supported music as a low-cost, simple alternative to traditional methods of management, with minimal risk to the client. A rating system assigning levels of evidence to support these interventions was used, and implications for nursing practice innovations and further research are discussed.

Research on subgroups is not research on equity attributes: Evidence from an overview of systematic reviews on vaccination.

Equity remains a priority in the international health development agenda. However, major inequities in vaccination coverage jeopardise the achievement of the Sustainable Development Goals. We aim at comprehensively describing how research has addressed equity issues related to vaccination. We carried out an overview of systematic reviews (SRs) that explicitly explored the effects of interventions to improve vaccination in any context; for any vaccine and, in any language. We followed standard research synthesis methods to systematically search for SR, assess them for inclusion and extracting relevant data, particularly on vaccination related outcomes. To gather evidence on equity issues addressed in the SR, we used the PROGRESS-plus framework. Our search obtained 2,003 hits which resulted in 54 included SRs, published between 1994 and 2014. The quality of SRs was generally poor, with less than half complying with most of the quality criteria. Reported vaccines included, by order of frequency, influenza and Expanded Programme on Immunisation vaccines. The types of interventions more frequently reported were related to vaccination delivery strategies, financial support and information, education and communication. Most of the SRs suggested effects favouring intervention groups as opposed to comparison groups. The most frequently reported equity attribute was 'place of residence' and the least reported equity attributes were sexual orientation and religion. Very few estimates of effects actually measured differences or changes between groups having those attributes and all of them referred to the place of residence. No data was found about reducing equity gaps for vulnerable groups or minorities, or attributes such as sexual orientation, education or specific religious groups. Although research on vulnerable populations as a subgroup is abundant, it fails to report on the interventions that will actually reduce inequities and consider how redistribution of health care

Research literacy and the practice of evidence-based medicine (EBM) are important initiatives in complementary and alternative medicine (CAM), which requires cultural change within educational institutions for successful implementation. To determine the self-assessed research and EBM perspectives of Chinese medicine Masters degree students at Pacific College of Oriental Medicine, New York campus (PCOM-NY). A survey with 17 close-ended questions and one open-ended question was administered through Survey Monkey to students at PCOM-NY. The survey was sent to 420 Masters students and 176 (41.9%) responded. Students in all four years of the Masters degree indicated a generally high degree of interest in, and support for the value of research. However, increasing years (one to four years) in the program was associated with lower interest in post-graduation research participation and entering the doctoral program, and the fourth year students reported low levels of interest in having greater research content and training in their Masters degree programs. Students who responded to the open-ended question (23% of respondents) expressed enthusiasm for research and concerns about the relevance of research in Chinese medicine. Consistent with findings in similar studies at CAM colleges, interest in research, and EBM of the PCOM-NY Masters students appeared to decline with increasing years in the program. Concerns around paradigm and epistemological issues associated with research and EBM among Chinese medicine students and practitioners warrants further investigation, and may be an important challenge for integrative medicine.

Review of NASA's Evidence Reports on Human Health Risks. 2015 Letter Report

Science.gov (United States)

Scott-Conner, Carol E. H.; Masys, Daniel R.; Liverman, Catharyn T.

2016-01-01

NASA has requested a study from the Institute of Medicine (IOM) to provide an independent review of more than 30 evidence reports on human health risks for long duration and exploration spaceflight. The evidence reports, which are publicly available, are categorized into five broad categories: (1) behavioral health and performance; (2) human health countermeasures (with a focus on bone metabolism and orthopedics, nutrition, immunology, and cardiac and pulmonary physiology); (3) radiation; (4) human factors issues; and (5) exploration medical capabilities. The reports are revised on an ongoing basis to incorporate new scientific information. In conducting this study, an IOM ad hoc committee will build on the 2008 IOM report Review of NASA's Human Research Program Evidence Books. That report provided an assessment of the process used for developing the evidence reports and provided an initial review of the evidence reports that had been completed at that time. Each year, NASA staff will identify a set of evidence reports for committee review. Over the course of the study all evidence reports will be reviewed. The committee will hold an annual scientific workshop to receive input on the evidence reports it is reviewing that year and an update on the recent literature. The committee will issue an annual letter report that addresses the following questions relevant to each evidence report: 1. Does the evidence report provide sufficient evidence, as well as sufficient risk context, that the risk is of concern for long-term space missions? 2. Does the evidence report make the case for the research gaps presented? 3. Are there any additional gaps in knowledge or areas of fundamental research that should be considered to enhance the basic understanding of this specific risk? 4. Does the evidence report address relevant interactions among risks? 5. Is input from additional disciplines needed? 6. Is the breadth of the cited literature sufficient? 7. What is the overall

Reflections on relevance: Psychotherapy and Psychosomatics in 2004.

Science.gov (United States)

Balon, Richard

2005-01-01

Relevance of an article is a highly desirable yet hardly predictable quality at the time of its publication. Article relevance is frequently measured by the impact factor of the journal where the article is published. Furthermore, impact factor, citation index and citation analysis are used as a measure of research progress and scientific wealth of a nation. The wisdom and significance of this approach to relevance is debatable and thus discussed here. In 2004, Psychotherapy and Psychosomatics published a variety of articles which, in the author's view, are clinically relevant. Several selected clinically relevant issues reviewed in this article include: the conceptualization of fibromyalgia as a stress disorder; the psychosocial impact and psychosocial interventions in cancer; the impact of alexithymia on patient care; the possible relationship between depression and nutrition (namely intake of folate and pyridoxal phosphate); the significance of hypercoagulability in panic-like anxiety; the questionable value of single isomer drugs, and the relevance and adequacy of clinimetrics versus psychometrics in clinical research. The reviewed issues seem to be relevant to clinical practice, research or both, but also to our critical thinking, and the critical review of the developments in psychiatry and psychology.

An evidence-based patient-centered method makes the biopsychosocial model scientific.

Smith, Robert C; Fortin, Auguste H; Dwamena, Francesca; Frankel, Richard M

To review the scientific status of the biopsychosocial (BPS) model and to propose a way to improve it. Engel's BPS model added patients' psychological and social health concerns to the highly successful biomedical model. He proposed that the BPS model could make medicine more scientific, but its use in education, clinical care, and, especially, research remains minimal. Many aver correctly that the present model cannot be defined in a consistent way for the individual patient, making it untestable and non-scientific. This stems from not obtaining relevant BPS data systematically, where one interviewer obtains the same information another would. Recent research by two of the authors has produced similar patient-centered interviewing methods that are repeatable and elicit just the relevant patient information needed to define the model at each visit. We propose that the field adopt these evidence-based methods as the standard for identifying the BPS model. Identifying a scientific BPS model in each patient with an agreed-upon, evidence-based patient-centered interviewing method can produce a quantum leap ahead in both research and teaching. A scientific BPS model can give us more confidence in being humanistic. In research, we can conduct more rigorous studies to inform better practices. Copyright © 2013 Elsevier Ireland Ltd.

What is Evidence? (editorial

. That does not mean that we can just rely on these experiences, however, but rather that through reflection and critical thinking we will see where things may be improved and begin to investigate ways to make them better. Without that initial evidence coming from our experience, we would not even know how or when to question or critique such things. Hence, the initial evidence of “what do I know” becomes an area that is crucial to future research that will be of value to practice improvement.We need to start thinking about how we put all these different pieces of evidence together to make the best decisions possible. I don’t write this to dismiss what those in the EBLIP movement are doing (certainly, I am part of that movement, and hope to contribute to its progression. Rather, I pose these things as considerations and challenges for us to make evidence-based/evidence-informed/practice-based evidence, better and more applicable to practitioners.So, what does this journal do to aid in pulling together these different pieces of evidence? Well, first and foremost we publish in an open access manner so anyone who needs to can access the content we provide. The types of evidence we publish in this journal are varied, but we have taken several different approaches. Firstly, we publish relevant research that has been vetted through peer review. This is a traditional role in publishing scholarly work, and we believe it is important. Secondly, we publish evidence that comes from critically appraising previously published studies – this is a type of meta-evidence wherein writers of evidence summaries must bring their professional experience and training to bear on the critiques they write. It lends readers another professional opinion (also vetted through peer review, to help educate and inform readers to make up their mind about the quality and value of the original research study. The same can be said of our “classics” which entail the same process but with works

Rationalising prescribing: Evidence, marketing and practice-relevant knowledge.

Science.gov (United States)

Wadmann, Sarah; Bang, Lia E

2015-06-01

Initiatives in the name of 'rational pharmacotherapy' have been launched to alter what is seen as 'inappropriate' prescribing practices of physicians. Based on observations and interviews with 20 general practitioners (GPs) in 2009-2011, we explored how attempts to rationalise prescribing interact with chronic care management in Denmark. We demonstrate how attempts to rationalise prescribing by informing GPs about drug effects, adverse effects and price do not satisfy GPs' knowledge needs. We argue that, for GPs, 'rational' prescribing cannot be understood in separation from the processes that enable patients to use medication. Therefore, GPs do much more to obtain knowledge about medications than seek advice on 'rational pharmacotherapy'. For instance, GPs also seek opportunities to acquaint themselves with the material objects of medication and medical devices. We conceptualise the knowledge needs of GPs as a need for practice-relevant knowledge and argue that industry sales representatives are granted opportunity to access general practice because they understand this need of GPs.

The GRADE-CERQual ('Confidence in the Evidence from Reviews of Qualitative research') approach provides guidance for assessing how much confidence to place in findings from systematic reviews of qualitative research (or qualitative evidence syntheses). The approach has been developed to support the use of findings from qualitative evidence syntheses in decision-making, including guideline development and policy formulation. Confidence in the evidence from qualitative evidence syntheses is an assessment of the extent to which a review finding is a reasonable representation of the phenomenon of interest. CERQual provides a systematic and transparent framework for assessing confidence in individual review findings, based on consideration of four components: (1) methodological limitations, (2) coherence, (3) adequacy of data, and (4) relevance. A fifth component, dissemination (or publication) bias, may also be important and is being explored. As with the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach for effectiveness evidence, CERQual suggests summarising evidence in succinct, transparent, and informative Summary of Qualitative Findings tables. These tables are designed to communicate the review findings and the CERQual assessment of confidence in each finding. This article is the first of a seven-part series providing guidance on how to apply the CERQual approach. In this paper, we describe the rationale and conceptual basis for CERQual, the aims of the approach, how the approach was developed, and its main components. We also outline the purpose and structure of this series and discuss the growing role for qualitative evidence in decision-making. Papers 3, 4, 5, 6, and 7 in this series discuss each CERQual component, including the rationale for including the component in the approach, how the component is conceptualised, and how it should be assessed. Paper 2 discusses how to make an overall assessment of confidence in a review

Randomised controlled trials can provide evidence relevant to assessing the equity impact of an intervention, but such information is often poorly reported. We describe a conceptual framework to identify health equity-relevant randomised trials with the aim of improving the design and reporting of such trials. An interdisciplinary and international research team engaged in an iterative consensus building process to develop and refine the conceptual framework via face-to-face meetings, teleconferences and email correspondence, including findings from a validation exercise whereby two independent reviewers used the emerging framework to classify a sample of randomised trials. A randomised trial can usefully be classified as 'health equity relevant' if it assesses the effects of an intervention on the health or its determinants of either individuals or a population who experience ill health due to disadvantage defined across one or more social determinants of health. Health equity-relevant randomised trials can either exclusively focus on a single population or collect data potentially useful for assessing differential effects of the intervention across multiple populations experiencing different levels or types of social disadvantage. Trials that are not classified as 'health equity relevant' may nevertheless provide information that is indirectly relevant to assessing equity impact, including information about individual level variation unrelated to social disadvantage and potentially useful in secondary modelling studies. The conceptual framework may be used to design and report randomised trials. The framework could also be used for other study designs to contribute to the evidence base for improved health equity. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Motor Development and Motor Resonance Difficulties in Autism: Relevance to Early Intervention for Language and Communication Skills

Directory of Open Access Journals (Sweden)

Joseph P. Mccleery

2013-04-01

Full Text Available Research suggests that a sub-set of children with autism experience notable difficulties and delays in motor skills development, and that a large percentage of children with autism experience deficits in motor resonance. These motor-related deficiencies, which evidence suggests are present from a very early age, are likely to negatively affect social-communicative and language development in this population. Here, we review evidence for delayed, impaired, and atypical motor development in infants and children with autism. We then carefully review and examine the current language and communication-based intervention research that is relevant to motor and motor resonance (i.e., neural mirroring mechanisms activated when we observe the actions of others deficits in children with autism. Finally, we describe research needs and future directions and developments for early interventions aimed at addressing the speech/language and social-communication development difficulties in autism from a motor-related perspective.

Providing evidence of impact highlights the benefits of medical research to society. Such evidence is increasingly requested by research funders and commonly relies on citation analysis. However, other indicators may be more informative. Although frameworks to demonstrate the impact of clinical research have been reported, no complementary framework exists for methodological research. Therefore, we assessed the impact of methodological research projects conducted or completed between 2009 and 2012 at the UK Medical Research Council Clinical Trials Unit Hub for Trials Methodology Research Hub, with a view to developing an appropriate framework. Various approaches to the collection of data on research impact were employed. Citation rates were obtained using Web of Science (http://www.webofknowledge.com/) and analyzed descriptively. Semistructured interviews were conducted to obtain information on the rates of different types of research output that indicated impact for each project. Results were then pooled across all projects. Finally, email queries pertaining to methodology projects were collected retrospectively and their content analyzed. Simple citation analysis established the citation rates per year since publication for 74 methodological publications; however, further detailed analysis revealed more about the potential influence of these citations. Interviews that spanned 20 individual research projects demonstrated a variety of types of impact not otherwise collated, for example, applications and further developments of the research; release of software and provision of guidance materials to facilitate uptake; formation of new collaborations and broad dissemination. Finally, 194 email queries relating to 6 methodological projects were received from 170 individuals across 23 countries. They provided further evidence that the methodologies were impacting on research and research practice, both nationally and internationally. We have used the information

Clinical epidemiology is the science of human disease investigation with a focus on diagnosis, prognosis, and treatment. The generation of a reasonable question requires definition of patients, interventions, controls, and outcomes. The goal of research design is to minimize error, to ensure adequate samples, to measure input and output variables appropriately, to consider external and internal validities, to limit bias, and to address clinical as well as statistical relevance. The hierarchy of evidence for clinical decision-making places randomized controlled trials (RCT) or systematic review of good quality RCTs at the top of the evidence pyramid. Prognostic and etiologic questions are best addressed with longitudinal cohort studies.

A Literature Review of Homelessness and Aging: Suggestions for a Policy and Practice-Relevant Research Agenda.

Homelessness among older people is a growing concern across Canada and is expected to rise with demographic change (Crane & Warnes, 2010; Culhane, Metraux, Byrne, Stino, & Bainbridge, 2013). Yet current knowledge, policies, and practices on homelessness largely focus on younger populations. Likewise, research and policies on aging typically overlook homelessness. Responses to homelessness among older people must address complex needs related to health, income security, and housing. Based on a comprehensive literature review, this article outlines the existing and needed research with regards to homelessness among older people. We clarify the intersections of aging and homelessness; review the relevant statistics, including estimated prevalence; discuss pathways and variations in experience; and identify gaps in knowledge. We conclude with a call for an inclusive research agenda that will help build policies and practices to reduce and ultimately to eliminate homelessness among older people in Canada.

An assessment of maternal, newborn and child health implementation studies in Nigeria: implications for evidence informed policymaking and practice

Chigozie Jesse Uneke

2016-08-01

Full Text Available Background: The introduction of implementation science into maternal, newborn and child health (MNCH research has facilitated better methods to improve uptake of research findings into practices. With increase in implementation research related to MNCH world-wide, stronger scientific evidence are now available and have improved MNCH policies in many countries including Nigeria. The purpose of this study was to review MNCH implementation studies undertaken in Nigeria in order to understand the extent the evidence generated informed better policy. Methods: This study was a systematic review. A MEDLINE Entrez PubMed search was performed in August 2015 and implementation studies that investigated MNCH in Nigeria from 1966 to 2015 in relation to health policy were sought. Search key words included Nigeria, health policy,maternal, newborn, and child health. Only policy relevant studies that were implementation or intervention research which generated evidence to improve MNCH in Nigeria were eligible and were selected. Results: A total of 18 relevant studies that fulfilled the study inclusion criteria were identified out of 471 studies found. These studies generated high quality policy relevance evidence relating to task shifting, breastfeeding practices, maternal nutrition, childhood immunization, kangaroo mother care (KMC, prevention of maternal to child transmission of HIV, etc. These indicated significant improvements in maternal health outcomes in localities and health facilities where the studies were undertaken. Conclusion: There is a dire need for more implementation research related to MNCH in low income settings because the priority for improved MNCH outcome is not so much the development of new technologies but solving implementation issues, such as how to scale up and evaluate interventions within complex health systems.

Approximately 80% of research evidence relevant to clinical practice never reaches the clinicians delivering patient care. A key barrier for the translation of evidence into practice is the limited time and skills clinicians have to find and appraise emerging evidence. Social media may provide a bridge between health researchers and health service providers. The aim of this study was to determine the efficacy of social media as an educational medium to effectively translate emerging research evidence into clinical practice. The study used a mixed-methods approach. Evidence-based practice points were delivered via social media platforms. The primary outcomes of attitude, knowledge, and behavior change were assessed using a preintervention/postintervention evaluation, with qualitative data gathered to contextualize the findings. Data were obtained from 317 clinicians from multiple health disciplines, predominantly from the United Kingdom, Australia, the United States, India, and Malaysia. The participants reported an overall improvement in attitudes toward social media for professional development (P<.001). The knowledge evaluation demonstrated a significant increase in knowledge after the training (P<.001). The majority of respondents (136/194, 70.1%) indicated that the education they had received via social media had changed the way they practice, or intended to practice. Similarly, a large proportion of respondents (135/193, 69.9%) indicated that the education they had received via social media had increased their use of research evidence within their clinical practice. Social media may be an effective educational medium for improving knowledge of health professionals, fostering their use of research evidence, and changing their clinical behaviors by translating new research evidence into clinical practice.

Full Text Available Background: Nutrition is the intake of food in relation to the body's dietary needs. Malnutrition results from the intake of inadequate or excess food. This can lead to reduced immunity, increased susceptibility to disease, impaired physical and mental development, and reduced productivity. Objective: To perform a systematic review to assess research conducted by the International Network for the Demographic Evaluation of Populations and their Health (INDEPTH of health and demographic surveillance systems (HDSSs over a 15-year period on malnutrition, its determinants, the effects of under and over nutrition, and intervention research on malnutrition in low- and middle-income countries (LMICs. Methods: Relevant publication titles were uploaded onto the Zotero research tool from different databases (60% from PubMed. Using the keywords ‘nutrition’, ‘malnutrition’, ‘over and under nutrition’, we selected publications that were based only on data generated through the longitudinal HDSS platform. All titles and abstracts were screened to determine inclusion eligibility and full articles were independently assessed according to inclusion/exclusion criteria. For inclusion in this study, papers had to cover research on at least one of the following topics: the problem of malnutrition, its determinants, its effects, and intervention research on malnutrition. One hundred and forty eight papers were identified and reviewed, and 67 were selected for this study. Results: The INDEPTH research identified rising levels of overweight and obesity, sometimes in the same settings as under-nutrition. Urbanisation appears to be protective against under-nutrition, but it heightens the risk of obesity. Appropriately timed breastfeeding interventions were protective against malnutrition. Conclusions: Although INDEPTH has expanded the global knowledge base on nutrition, many questions remain unresolved. There is a need for more investment in nutrition research

Results The INDEPTH research identified rising levels of overweight and obesity, sometimes in the same settings as under-nutrition. Urbanisation appears to be protective against under-nutrition, but it heightens the risk of obesity. Appropriately timed breastfeeding interventions were protective against malnutrition. Conclusions Although INDEPTH has expanded the global knowledge base on nutrition, many questions remain unresolved. There is a need for more investment in nutrition research in LMICs in order to

Objective Our aim was to develop evidence-informed recommendations for rehabilitation with older adults living with HIV. Design We conducted a knowledge synthesis, combining research evidence specific to HIV, rehabilitation and ageing, with evidence on rehabilitation interventions for common comorbidities experienced by older adults with HIV. Methods We included highly relevant HIV-specific research addressing rehabilitation and ageing (stream A) and high-quality evidence on the effectiveness of rehabilitation interventions for common comorbidities experienced by older adults ageing with HIV (stream B). We extracted and synthesised relevant data from the evidence to draft evidence-informed recommendations for rehabilitation. Draft recommendations were refined based on people living with HIV (PLHIV) and clinician experience, values and preferences, reviewed by an interprofessional team for Grading of Recommendations Assessment, Development, and Evaluation (GRADE) (quality) rating and revision and then circulated to PLHIV and clinicians for external endorsement and final refinement. We then devised overarching recommendations to broadly guide rehabilitation with older adults living with HIV. Results This synthesis yielded 8 overarching and 52 specific recommendations. Thirty-six specific recommendations were derived from 108 moderate-level or high-level research articles (meta-analyses and systematic reviews) that described the effectiveness of rehabilitation interventions for comorbidities that may be experienced by older adults with HIV. Recommendations addressed rehabilitation interventions across eight health conditions: bone and joint disorders, cancer, stroke, cardiovascular disease, mental health challenges, cognitive impairments, chronic obstructive pulmonary disease and diabetes. Sixteen specific recommendations were derived from 42 research articles specific to rehabilitation with older adults with HIV. The quality of evidence from which these

Best estimates are often, out of necessity, from a context of less than quality evidence or needing more evidence to provide accuracy. Purpose: The purpose of this article is to understand the best estimate behavior, so that clinicians and patients may have confidence in its quantification and validation. Methods: To discover best estimates and quantify uncertainty, critical appraisals of the literature, gray literature and its resources, or both are accomplished. Best estimates of pairwise comparisons are calculated using meta-analytic methods; multiple comparisons use network meta-analysis. Manufacturers provide margins of performance of proprietary material(s. Lower margin performance thresholds or requirements (functional failure of materials are determined by a distribution of tests to quantify performance or clinical competency. The same is done for the high margin performance thresholds (estimated true value of success and clinician-derived critical values (material failure to function clinically. This quantification of margins and uncertainties assists clinicians in determining if reported best estimates are progressing toward true value as new knowledge is reported. Analysis: The best estimate of outcomes focuses on evidence-centered care. In stochastic environments, we are not able to observe all events in all situations to know without uncertainty the best estimates of predictable outcomes. Point-in-time analyses of best estimates using quantification of margins and uncertainties do this. Conclusion: While study design and methodology are variables known to validate the quality of

Full Text Available Abstract Background Community-based organizations (CBOs are important stakeholders in health systems and are increasingly called upon to use research evidence to inform their advocacy, program planning, and service delivery. To better support CBOs to find and use research evidence, we sought to assess the capacity of CBOs in the HIV/AIDS sector to acquire, assess, adapt, and apply research evidence in their work. Methods We invited executive directors of HIV/AIDS CBOs in Ontario, Canada (n = 51 to complete the Canadian Health Services Research Foundation's "Is Research Working for You?" survey. Findings Based on responses from 25 organizations that collectively provide services to approximately 32,000 clients per year with 290 full-time equivalent staff, we found organizational capacity to acquire, assess, adapt, and apply research evidence to be low. CBO strengths include supporting a culture that rewards flexibility and quality improvement, exchanging information within their organization, and ensuring that their decision-making processes have a place for research. However, CBO Executive Directors indicated that they lacked the skills, time, resources, incentives, and links with experts to acquire research, assess its quality and reliability, and summarize it in a user-friendly way. Conclusion Given the limited capacity to find and use research evidence, we recommend a capacity-building strategy for HIV/AIDS CBOs that focuses on providing the tools, resources, and skills needed to more consistently acquire, assess, adapt, and apply research evidence. Such a strategy may be appropriate in other sectors and jurisdictions as well given that CBO Executive Directors in the HIV/AIDS sector in Ontario report low capacity despite being in the enviable position of having stable government infrastructure in place to support them, benefiting from long-standing investment in capacity building, and being part of an active provincial network.

Full Text Available Background: A significant challenge in research translation is that interested parties interpret and apply the associated terms and conceptual frameworks in different ways. The purpose of this review was to: a examine different research translation frameworks; b examine the similarities and differences between the frameworks; and c identify key strengths and weaknesses of the models when they are applied in practice. Methods: The review involved a keyword search of PubMed. The search string was (translational research OR knowledge translation OR evidence to practice AND (framework OR model OR theory AND (public health OR health promotion OR medicine. Included studies were published in English between January 1990 and December 2014, and described frameworks, models or theories associated with research translation. Results: The final review included 98 papers, and 41 different frameworks and models were identified. The most frequently applied knowledge translation framework in the literature was RE-AIM, followed by the knowledge translation continuum or ‘T’ models, the Knowledge to Action framework, the PARiHS framework, evidence based public health models, and the stages of research and evaluation model. Conclusion: The models identified in this review stem from different fields, including implementation science, basic and medical sciences, health services research and public health, and propose different but related pathways to closing the research–practice gap.

This paper empirically analyses the antecedents of citizens’ perceptions of the relevance of international climate policy. Its use of representative surveys in the USA, China and Germany controls for different environmental attitudes and socio-economic factors between countries. The findings of the micro-econometric analysis suggest that the perceived relevance of international climate policy is positively affected by its perceived effectiveness, approval of the key topics discussed at international climate conferences, and environmental attitudes, but is not affected by perceived procedural justice. A higher level of perceived trust in international climate policy was positively related to perceived relevance in the USA and in China, but not in Germany. Citizens who felt that they were well informed and that their position was represented at climate summits were more likely to perceive international climate policy as relevant in China in particular. Generally, the results show only weak evidence of socio-demographic effects. - Highlights: • Perceptions of climate-policy relevance increase with perceptions of effectiveness. • In China and the USA, trust increases perceptions of climate-policy relevance. • Environmental attitudes are related to perceptions of climate-policy relevance. • In China, well-informed citizens perceive climate policy as more relevant. • Socio-demographics only weakly affect perceptions of climate-policy relevance.

Full Text Available In February 2016, the Minister of Health decided to increase the use of research findings in improving the quality of the national health policy and planning. The Ministry of Health has instructed the National Institute of Health Research and Development or NIHRD to play a stronger role of monitoring and evaluating all health programs, because “their opinion and research findings should be the basis for changes in national health policies and planning”. Compared to the past, the Ministry of Health has increased the research budget for evidence-based research tremendously. However, there is a gap between the information needs of program and policy-makers and the information offered by researchers. A close dialogue is needed between the users (program managers, policy makers and planners and the suppliers (researchers and evaluators to ensure that the evidence-based supplied by research is useful for programs, planning and health policy.

The Australian Nuclear Science and Technology Organisation (ANSTO) has established a project to undertake research relevant to the safety case for the proposed Australian radioactive waste facility. This facility will comprise a store for intermediate level radioactive waste, and either a store or a near-surface repository for low-level waste. In order to identify the research priorities for this project, a structured analysis of the features, events and processes (FEPs) relevant to the performance of the facility was undertaken. This analysis was based on the list of 137 FEPs developed by the IAEA project on 'Safety Assessment Methodologies for Near Surface Disposal Facilities' (ISAM). A number of key research issues were identified, and some factors which differ in significance for the store, compared to the repository concept, were highlighted. For example, FEPs related to long-term groundwater transport of radionuclides are considered to be of less significance for a store than a repository. On the other hand, structural damage from severe weather, accident or human interference is more likely for a store. The FEPs analysis has enabled the scientific research skills required for the inter-disciplinary project team to be specified. The outcomes of the research will eventually be utilised in developing the design, and assessing the performance, of the future facility. It is anticipated that a more detailed application of the FEPs methodology will be undertaken to develop the safety case for the proposed radioactive waste management facility. (authors)

In response to policy recommendations, nine National Institute for Health Research (NIHR) Collaborations for Leadership in Applied Health Research and Care (CLAHRCs) were established in England in 2008, aiming to create closer working between the health service and higher education and narrow the gap between research and its implementation in practice. The Greater Manchester (GM) CLAHRC is a partnership between the University of Manchester and twenty National Health Service (NHS) trusts, with a five-year mission to improve healthcare and reduce health inequalities for people with cardiovascular conditions. This paper outlines the GM CLAHRC approach to designing and evaluating a large-scale, evidence- and theory-informed, context-sensitive implementation programme. The paper makes a case for embedding evaluation within the design of the implementation strategy. Empirical, theoretical, and experiential evidence relating to implementation science and methods has been synthesised to formulate eight core principles of the GM CLAHRC implementation strategy, recognising the multi-faceted nature of evidence, the complexity of the implementation process, and the corresponding need to apply approaches that are situationally relevant, responsive, flexible, and collaborative. In turn, these core principles inform the selection of four interrelated building blocks upon which the GM CLAHRC approach to implementation is founded. These determine the organizational processes, structures, and roles utilised by specific GM CLAHRC implementation projects, as well as the approach to researching implementation, and comprise: the Promoting Action on Research Implementation in Health Services (PARIHS) framework; a modified version of the Model for Improvement; multiprofessional teams with designated roles to lead, facilitate, and support the implementation process; and embedded evaluation and learning. Designing and evaluating a large-scale implementation strategy that can cope with and

Human and veterinary active pharmaceutical ingredients (APIs) are involved in contamination of surface water, ground water, effluents, sediments and biota. Effluents of waste water treatment plants and hospitals are considered as major sources of such contamination. However, recent evidences reveal high concentrations of a large number of APIs in effluents from pharmaceutical factories and in receiving aquatic ecosystems. Moreover, laboratory exposures to these effluents and field experiments reveal various physiological disturbances in exposed aquatic organisms. Also, it seems to be relevant to increase knowledge on this route of contamination but also to develop specific approaches for further environmental monitoring campaigns. The present study summarizes available data related to the impact of pharmaceutical factory discharges on aquatic ecosystem contaminations and presents associated challenges for scientists and environmental managers.

In the worlds inhabited by qualitative inquirers working in health-related areas, health care, evidence, qualitative research, and qualitative researchers are four areas of potential tension and, at times, collision. These areas, or at least aspects of them, are constantly reinvented and realigned as the effects of such encounters are navigated. This article is about some of these close encounters, what we might learn from them, and how we might use this to "survive" as qualitative inquirers in an evidence-based world of health care and health care delivery.

Full Text Available This essay is a reflection on the peculiarities of the scientifically based research and on the distinctive elements of the EBL (evidence based learning, methodology used in the study on the “Relationship between Metacognition, Self-efficacy and Self-regulation in Learning”. The EBL method, based on the standardization of data, explains how the students’ learning experience can be considered as a set of “data” and can be used to explain how and when the research results can be considered generalizable and transferable to other learning situations. The reflections present in this study have also allowed us to illustrate the impact that its results have had on the micro and macro level of reality. They helped to fill in the gaps concerning the learning/teaching processes, contributed to the enrichment of the scientific literature on this subject and allowed to establish standards through rigorous techniques such as systematic reviews and meta-analysis.

Proposal of a Holistic Model to Support Local-Level Evidence-Based Practice

Said Shahtahmasebi

Full Text Available In response to a central drive for evidence-based practice, there have been many research support schemes, setups, and other practices concentrating on facilitating access to external research, such as the Centre for Evidence Based Healthcare Aotearoa, the Cochrane Collaboration, and the York Centre for Reviews and Dissemination. Very little attention has been paid to supporting internal research in terms of local evidence and internal research capabilities. The whole evidence-based practice movement has alienated internal decision makers and, thus, very little progress has been made in the context of evidence informing local policy formation. Health and social policies are made centrally based on dubious claims and often evidence is sought after implementation. For example, on record, most health care practitioners appear to agree with the causal link between depression and mental illness (sometimes qualified with other social factors with suicide; off the record, even some psychiatrists doubt that such a link is applicable to the population as a whole. Therefore, be it through misplaced loyalty or a lack of support for internal researchers/decision makers, local evidence informing local decision making may have been ignored in favour of external evidence. In this paper, we present a practical holistic model to support local evidence-based decision making. This approach is more relevant in light of a new approach to primary health care of “local knowledge” complementing external evidence. One possible outcome would be to network with other regional programmes around the world to share information and identify “best” practices, such as the “Stop Youth Suicide Campaign”(www.stopyouthsuicide.com.

In this introduction to the special issue on current thinking in qualitative research and occupational therapy and science, the authors focus on the importance of rigorous qualitative research to inform occupational therapy practice. The authors chosen for this special issue reflect a "second generation of qualitative researchers" who are critical, theoretically sophisticated, methodologically productive, and politically relevant to show that working with disabled clients is political work. Three themes emerged across the articles included in this special issue: (1) recognizing and addressing social justice issues; (2) learning from clients' experiences; and (3) critically reframing occupational therapy's role. These themes can inform occupational therapy practice, research, and education to reflect a more client-centered and politically engaging approach. Copyright 2012, SLACK Incorporated.

The Main purpose of vocational rehabilitation is occupational reintegration of clients into the job market who have lost their job or whose job is threatened because of a handicap or chronicl illness. With regard to existing evidence for the relevance of personality factors for work performance and job achievement, the present study investigated the influence of participants' personality factors on a successful reintegration after a retraining program in a vocational training center over 2 years. A central research objective was to identify prognostic personality factors for successful vocational integration. In this longitudinal study 15 vocational training centers participated at 3 time points of measurement (T1, T2 and T3). Data gathering was based on rehabilitants' self-reports (standardized questionnaires: SVF, BSW, SPR, CSES) about personality aspects. First data collection started at the beginning (T1) and a second survey was conducted at the end of the training 2 years later (T2). Based on the data at measurement points T1 and T2, 4 prognostic models were computed (binary logistic regression analysis) and evaluated, examining the differenzial influence of several scales and items on direct reintegration after completing the vocational retraining and reintegration status 6 months later (T3). As expected, different variables turned out to be relevant for occupational integration at the end of the training program and 6 months later. Correspondingly other variables appeared to be relevant for occupational reintegration at T1 and at T2. At the end of the vocational training program, approximately 24% of the participants had a job. With respect to direct reintegration, regression analysis revealed that vocational self-efficacy (R(2)=0,175) and self-evaluation were relevant (R(2)=0,383). Approximately 70% of the participants had gotten a job 6 months later. Several stress coping strategies (R(2)=0,170), estimation of the own reintegration prognosis and aspects

The emerging field of the psychophysiology of motivation bears many new findings, but little replication. Using my own data (Kreibig, Gendolla, & Scherer, 2012), I test the reproducibility of this specific study, provide the necessary materials to make the study reproducible, and instantiate proper reproducibility practices that other researchers can use as a road map toward the same goal. In addition, based on re-analyses of the original data, I report new evidence for the motivational effects of emotional responding to performance feedback. Specifically, greater appraisal of goal relevance amplifies the emotional response to events appraised as conducive (i.e., effort mobilization), but not to those appraised as obstructive to a person's goals (i.e., effort withdrawal). I conclude by providing a ten-step road map of best practices to facilitate computational reproducibility for future studies. Copyright © 2017 Elsevier B.V. All rights reserved.

Nursing is an integral part of all healthcare services, and has the potential of having a wide and enduring impact on health outcomes for a global ageing population. Over time nurses have developed new roles and assumed greater responsibilities. It is increasingly important to demonstrate the safety and overall impact of nurses' practice through research, to support the case for greater investment and development of nursing services around the world. To provide an overview of existing research evidence on the impact of nursing on patient outcomes, identify gaps in evidence, and point to future priorities for global research. Specifically to address two questions: what is the evidence that nursing contributes to improving the health and well-being of populations?; and where should research activity be focused to strengthen the evidence base for the impact of nursing? A search of the literature from 1996 using CINAHL, MEDLINE, the Cochrane Library, Google Scholar and the NICE evidence databases using the key words: nursing, nurse led, nursing interventions and patient outcomes. Initial analysis of the retrieved citations to reveal clusters of evidence of nursing impact in clinical areas which had been subject to systematic/integrative reviews or meta-analyses. Further analysis of these reviews to provide an overview of the research evidence for nurses' contributions to healthcare to inform discussion on future research agendas. We use the terms low, moderate and high quality evidence to reflect the assessments made by the review authors whose work is presented throughout. Analysis of 61 reviews, including ten Cochrane reviews and two scoping/selective reviews to provide a summary of the research evidence for nurses' contributions to healthcare in the following areas of practice: nursing in acute care settings; nurses' involvement in public health; the contribution of specialist nurse and nurse-led services to the management of chronic disease; comparison of care

WBC is increasingly accessible to athletes, and is purported to enhance recovery after exercise and facilitate rehabilitation postinjury. Our objective was to review the efficacy and effectiveness of WBC using empirical evidence from controlled trials. We found ten relevant reports; the majority were based on small numbers of active athletes aged less than 35 years. Although WBC produces a large temperature gradient for tissue cooling, the relatively poor thermal conductivity of air prevents significant subcutaneous and core body cooling. There is weak evidence from controlled studies that WBC enhances antioxidant capacity and parasympathetic reactivation, and alters inflammatory pathways relevant to sports recovery. A series of small randomized studies found WBC offers improvements in subjective recovery and muscle soreness following metabolic or mechanical overload, but little benefit towards functional recovery. There is evidence from one study only that WBC may assist rehabilitation for adhesive capsulitis of the shoulder. There were no adverse events associated with WBC; however, studies did not seem to undertake active surveillance of predefined adverse events. Until further research is available, athletes should remain cognizant that less expensive modes of cryotherapy, such as local ice-pack application or cold-water immersion, offer comparable

While each process is associated with its unique characteristics, overlaps are likely to appear between each of the two processes. For instance, in the EBP process, if one discovers (theory that evidence is inadequate to implement a certain intervention, it highlights the need for research on that specific subject. Similarly, QI may lead to the identification of new questions, which could be used for research purposes. All the discussed processes, as well as their scientific and professional dimensions, are essential to nursing disciplines in healthcare systems.

Using mixed methods research in medical education: basic guidelines for researchers.

2009-07-01

Mixed methods research involves the collection, analysis and integration of both qualitative and quantitative data in a single study. The benefits of a mixed methods approach are particularly evident when studying new questions or complex initiatives and interactions, which is often the case in medical education research. Basic guidelines for when to use mixed methods research and how to design a mixed methods study in medical education research are not readily available. The purpose of this paper is to remedy that situation by providing an overview of mixed methods research, research design models relevant for medical education research, examples of each research design model in medical education research, and basic guidelines for medical education researchers interested in mixed methods research. Mixed methods may prove superior in increasing the integrity and applicability of findings when studying new or complex initiatives and interactions in medical education research. They deserve an increased presence and recognition in medical education research.

The value placed on types of evidence within decision-making contexts is highly dependent on individuals, the organizations in which the work and the systems and sectors they operate in. Decision-making processes too are highly contextual. Understanding the values placed on evidence and processes guiding decision-making is crucial to designing strategies to support evidence-informed decision-making (EIDM). This paper describes how evidence is used to inform local government (LG) public health decisions. The study used mixed methods including a cross-sectional survey and interviews. The Evidence-Informed Decision-Making Tool (EvIDenT) survey was designed to assess three key domains likely to impact on EIDM: access, confidence, and organizational culture. Other elements included the usefulness and influence of sources of evidence (people/groups and resources), skills and barriers, and facilitators to EIDM. Forty-five LGs from Victoria, Australia agreed to participate in the survey and up to four people from each organization were invited to complete the survey (n = 175). To further explore definitions of evidence and generate experiential data on EIDM practice, key informant interviews were conducted with a range of LG employees working in areas relevant to public health. In total, 135 responses were received (75% response rate) and 13 interviews were conducted. Analysis revealed varying levels of access, confidence and organizational culture to support EIDM. Significant relationships were found between domains: confidence, culture and access to research evidence. Some forms of evidence (e.g. community views) appeared to be used more commonly and at the expense of others (e.g. research evidence). Overall, a mixture of evidence (but more internal than external evidence) was influential in public health decision-making in councils. By comparison, a mixture of evidence (but more external than internal evidence) was deemed to be useful in public health decision

This review describes published literature providing evidence for financial conflicts of interest in environmental and occupational health research. Secondary goals were to describe evidence that (a) utilized quantitative methods to evaluate the association of conflicts with study outcomes, and (b) assessed undisclosed as well as disclosed conflicts of interest. Forty-three studies were identified which contained descriptions of the impact of financial conflicts of interest on research results; 11 of these conducted quantitative analyses to demonstrate these relationships. All 11 articles which quantified associations identified significant associations of the presence of financial conflicts of interest with study findings. In studies which measured undisclosed conflicts, these comprised a substantial proportion of all conflicts.

To systematically review how process evaluations are currently designed, what methodologies are used and how are they developed alongside or within neurological rehabilitation trials. This mixed-methods systematic review had two evidence streams: stream I, studies reporting process evaluations alongside neurorehabilitation trials research and stream II, methodological guidance on process evaluation design and methodology. A search strategy was designed for each evidence stream. Data regarding process evaluation core concepts and design issues were extracted using a bespoke template. Evidence from both streams was analysed separately and then synthesised in a final overarching synthesis proposing a number of recommendations for future research. A total of 124 process evaluation studies, reporting on 106 interventions, were included in stream I evidence. 30 studies were included as stream II evidence. Synthesis 1 produced 9 themes, and synthesis 2 identified a total of 8 recommendations for process evaluation research. The overall synthesis resulted in 57 'synthesis recommendations' about process evaluation methodology grouped into 9 research areas, including the use of theory, the investigation of context, intervention staff characteristics and the delivery of the trial intervention. There remains no consensus regarding process evaluation terminology within the neurological rehabilitation field. There is a need for process evaluations to address the nature and influence of context over time. Process evaluations should clearly describe what intervention staff bring to a trial, including skills and experience prior to joining the research. Process evaluations should monitor intervention staff's learning effects and the possible impact that these may have on trial outcomes. Published by the BMJ Publishing Group Limited.

Nurses need a sound education in research and evidence-based practice (EBP) to provide patients with optimal care, but current teaching methods could be more effective. To evaluate the changes in nursing students 1) perceptions of research and EBP, 2) confidence in research and EBP, and 3) interest in research participation after completing a course in research and EBP. A pre-post assessment design was utilized to compare changes in students. This project was conducted at a small, private liberal arts institution with Bachelor of Science (BSN) students. Two cohorts of third-year BSN students (Year 1 N=55, Year 2 N=54) who were taking a required, semester-long Nursing Research and EBP course. Students' perceptions of and confidence in research and EBP were assessed pre- and post-semester using the Confidence in Research and EBP survey, which contained 7 demographic items, 9 Research Perceptions items, and 19 Confidence in Research items (5-point Likert scale; 1=Not at all confident, 5=Extremely confident). Two years of data were collected and analyzed in SPSS v.24.0. Wilcoxon signed-ranks tests and Mann-Whitney-U tests were utilized to examine the data. Students had significant improvements in perceptions of and confidence in research and EBP (pnursing practice. Copyright © 2017. Published by Elsevier Ltd.

Whole-body cryotherapy: empirical evidence and theoretical perspectives.

Bleakley, Chris M; Bieuzen, François; Davison, Gareth W; Costello, Joseph T

Whole-body cryotherapy (WBC) involves short exposures to air temperatures below -100°C. WBC is increasingly accessible to athletes, and is purported to enhance recovery after exercise and facilitate rehabilitation postinjury. Our objective was to review the efficacy and effectiveness of WBC using empirical evidence from controlled trials. We found ten relevant reports; the majority were based on small numbers of active athletes aged less than 35 years. Although WBC produces a large temperature gradient for tissue cooling, the relatively poor thermal conductivity of air prevents significant subcutaneous and core body cooling. There is weak evidence from controlled studies that WBC enhances antioxidant capacity and parasympathetic reactivation, and alters inflammatory pathways relevant to sports recovery. A series of small randomized studies found WBC offers improvements in subjective recovery and muscle soreness following metabolic or mechanical overload, but little benefit towards functional recovery. There is evidence from one study only that WBC may assist rehabilitation for adhesive capsulitis of the shoulder. There were no adverse events associated with WBC; however, studies did not seem to undertake active surveillance of predefined adverse events. Until further research is available, athletes should remain cognizant that less expensive modes of cryotherapy, such as local ice-pack application or cold-water immersion, offer comparable physiological and clinical effects to WBC.

Introduction to the special section on dissemination: dissemination research and research dissemination: how can we close the gap?

One of the greatest challenges facing health promotion and disease prevention is translating research findings into evidence-based public health and clinical practices that are actively disseminated and widely adopted. Despite the tremendous strides made in developing effective disease prevention and control programs, there has been little study of effective dissemination of evidence-based programs to and adoption by community, public health, and clinical practice settings. This special section provides a venue in which to highlight exemplary dissemination research efforts while also identifying limitations in research to date and framing important future research questions. This issue establishes a resource for investigators interested in dissemination research, with relevance to health psychology. In this sense, it can serve as a benchmark by which to examine subsequent progress. The 6 articles reflect the state of the science in dissemination research for the promotion and adoption of health behavior change interventions. (c) 2005 APA, all rights reserved

Quasi-experimental study designs series-paper 11: supporting the production and use of health systems research syntheses that draw on quasi-experimental study designs.

To describe the infrastructure available to support the production of policy-relevant health systems research syntheses, particularly those incorporating quasi-experimental evidence, and the tools available to support the use of these syntheses. Literature review. The general challenges associated with the available infrastructure include their sporadic nature or limited coverage of issues and countries, whereas the specific ones related to policy-relevant syntheses of quasi-experimental evidence include the lack of mechanism to register synthesis titles and scoping review protocols, the limited number of groups preparing user-friendly summaries, and the difficulty of finding quasi-experimental studies for inclusion in rapid syntheses and research syntheses more generally. Although some new tools have emerged in recent years, such as guidance workbooks and citizen briefs and panels, challenges related to using available tools to support the use of policy-relevant syntheses of quasi-experimental evidence arise from such studies potentially being harder for policymakers and stakeholders to commission and understand. Policymakers, stakeholders, and researchers need to expand the coverage and institutionalize the use of the available infrastructure and tools to support the use of health system research syntheses containing quasi-experimental evidence.

Three Research Strategies of Neuroscience and the Future of Legal Imaging Evidence.

Science.gov (United States)

Jun, Jinkwon; Yoo, Soyoung

2018-01-01

Neuroscientific imaging evidence (NIE) has become an integral part of the criminal justice system in the United States. However, in most legal cases, NIE is submitted and used only to mitigate penalties because the court does not recognize it as substantial evidence, considering its lack of reliability. Nevertheless, we here discuss how neuroscience is expected to improve the use of NIE in the legal system. For this purpose, we classified the efforts of neuroscientists into three research strategies: cognitive subtraction, the data-driven approach, and the brain-manipulation approach. Cognitive subtraction is outdated and problematic; consequently, the court deemed it to be an inadequate approach in terms of legal evidence in 2012. In contrast, the data-driven and brain manipulation approaches, which are state-of-the-art approaches, have overcome the limitations of cognitive subtraction. The data-driven approach brings data science into the field and is benefiting immensely from the development of research platforms that allow automatized collection, analysis, and sharing of data. This broadens the scale of imaging evidence. The brain-manipulation approach uses high-functioning tools that facilitate non-invasive and precise human brain manipulation. These two approaches are expected to have synergistic effects. Neuroscience has strived to improve the evidential reliability of NIE, with considerable success. With the support of cutting-edge technologies, and the progress of these approaches, the evidential status of NIE will be improved and NIE will become an increasingly important part of legal practice.

Evidence has the potential to be misleading if its value when expressing beliefs in hypotheses is not fully understood or presented. Although the knowledge base to understand uncertainties is growing, a challenge remains to prioritise research and to continuously assess the magnitude and consequences of misleading evidence in criminal cases. This study used a systematic content analysis to identify misleading evidence, drawing information from case transcripts of rulings argued unsafe by the Court of Appeal of England and Wales. In the 7-year study period, 218 applications were successful on appeal, containing 235 cases of misleading evidence. The majority (76%) of successful appeals were based upon the same materials available in the original trial, rather than the presentation of new relevant information. Witness (39%), forensic (32%), and character evidence (19%) were the most commonly observed evidence types, with the validity of witnesses (26%), probative value of forensic evidence (12%), and relevance of character evidence (10%) being the most prevalent combinations of identified issues. Additionally, the majority (66%) of misleading evidence types relate to their interpretation at activity level. The findings suggest that many of these misleading aspects could have been prevented by providing more transparency in the relationship between evidence and hypotheses. Generally, the results contribute to gaining a more complete picture of the role of misleading evidence in the criminal justice system. Copyright © 2017 The Authors. Published by Elsevier B.V.

To identify patterns in information sharing between a series of Chinese evidence based medicine (EBM) journals and the Cochrane Database of Systematic Reviews, to determine key evidence dissemination areas for EBM and to provide a scientific basis for improving the dissemination of EBM research. Data were collected on citing and cited from the Chinese Journal of Evidence-Based Medicine (CJEBM), Journal of Evidence-Based Medicine (JEBMc), Chinese Journal of Evidence Based Pediatrics (CJEBP), and the Cochrane Database of Systematic Reviews (CDSR). Relationships between citations were visualized. High-frequency key words from these sources were identified, to build a word co-occurrence matrix and to map research subjects. CDSR contains a large collection of information of relevance to EBM and its contents are widely cited across many journals, suggesting a well-developed citation environment. The content and citation of the Chinese journals have been increasing in recent years. However, their citation environments are much less developed, and there is a wide variation in the breadth and strength of their knowledge communication, with the ranking from highest to lowest being CJEBM, JEBMc and CJEBP. The content of CDSR is almost exclusively Cochrane intervention reviews examining the effects of healthcare interventions, so it's contribution to EBM is mostly in disease control and treatment. On the other hand, the Chinese journals on evidence-based medicine and practice focused more on areas such as education and research, design and quality of clinical trials, evidence based policymaking, evidence based clinical practice, tumor treatment, and pediatrics. Knowledge and findings of EBM are widely communicated and disseminated. However, citation environments and range of knowledge communication differ greatly between the journals examined in this study. This finds that Chinese EBM has focused mainly on clinical medicine, Traditional Chinese Medicine, pediatrics, tumor

Mode of action human relevance (species concordance) framework: Evolution of the Bradford Hill considerations and comparative analysis of weight of evidence.

The mode of action human relevance (MOA/HR) framework increases transparency in systematically considering data on MOA for end (adverse) effects and their relevance to humans. This framework continues to evolve as experience increases in its application. Though the MOA/HR framework is not designed to address the question of "how much information is enough" to support a hypothesized MOA in animals or its relevance to humans, its organizing construct has potential value in considering relative weight of evidence (WOE) among different cases and hypothesized MOA(s). This context is explored based on MOA analyses in published assessments to illustrate the relative extent of supporting data and their implications for dose-response analysis and involved comparisons for chemical assessments on trichloropropane, and carbon tetrachloride with several hypothesized MOA(s) for cancer. The WOE for each hypothesized MOA was summarized in narrative tables based on comparison and contrast of the extent and nature of the supporting database versus potentially inconsistent or missing information. The comparison was based on evolved Bradford Hill considerations rank ordered to reflect their relative contribution to WOE determinations of MOA taking into account increasing experience in their application internationally. This clarification of considerations for WOE determinations as a basis for comparative analysis is anticipated to contribute to increasing consistency in the application of MOA/HR analysis and potentially, transparency in separating science judgment from public policy considerations in regulatory risk assessment.

To evaluate the evidence for, and clinical relevance of, immediate and long-term effects of trunk restraint during reach-to-grasp training poststroke on movement patterns and functional abilities within the framework of the International Classification of Functioning, Disability and Health. PubMed, Web of Science, CINAHL, Embase, PEDro, Cochrane Library (publication dates January 1985 to March 2015). Randomized controlled trials comparing training using trunk restraint with any other exercise training. Data were extracted by one researcher and checked by two other researchers. The Cochrane Collaboration's tool for assessing risk of bias and the Physiotherapy Evidence Database scale were used by two researchers to assess study quality and risk of bias. Eight studies met the inclusion criteria. Five studies found better recovery of movement patterns (trunk displacement, elbow extension, and/or shoulder flexion - body function/structure) at post-test in the experimental compared with the control groups. Functional abilities (activity/participation) improved more in the experimental groups in 3 studies at post-test. Long-term effects were found in one study after 4 weeks. Trunk restraint has immediate and some long-term effects in adults with chronic stroke. However, these effects are not consistently clinically relevant when referring to minimal detectable change or minimal clinically important difference values.

Henderson, Amanda J; Davies, Jan; Willet, Michaela R

2006-11-01

This paper describes a qualitative program evaluation which sought to identify factors that either assist or impede the adoption of clinical evidence in everyday practice. Thirteen Australian projects were funded in a competitive grant program to adopt innovative strategies to improve the uptake of research evidence in everyday clinical practice. Project leaders' reports were analysed to collate common themes related to 1) critical elements in successful application of research knowledge, 2) barriers to implementing evidence, and 3) lessons for other organisations that might implement a similar project. Despite the diversity of the methods used to establish projects and the range of topics and clinical settings, many similarities were identified in the perceived critical success elements, barriers, and lessons for adopting clinical evidence. Eighteen themes emerged across the data including: leadership support; key stakeholder involvement; practice changes; communication; resources; education of staff; evaluation of outcomes; consumers; knowledge gaps; adoption/implementing staff; access to knowledge; risk assessment; collaboration; effectiveness of clinical research evidence; structure/organisation; cultural barriers; previous experiences; and information technology. Leaders of projects to adopt evidence in clinical practice identified barriers, critical success elements and lessons that impacted on their projects. A range of influences on the adoption of evidence were identified, and this knowledge can be used to assist others undertaking similar projects.

Retailing research: increasing the role of evidence in clinical services for childbirth.

Science.gov (United States)

Lomas, J

1993-01-01

A current review of the structures and assumptions of research transfer for clinical care reveals some progress from "passive diffusion" to "active dissemination" models, but little or no progress has been made toward targeting local influences on practitioner behavior for "coordinated implementation" of clinically relevant research into childbirth (or other) medical practices. The implementation of scientifically valid research syntheses, such as Effective Care in Pregnancy and Childbirth (ECPC), is therefore constrained by a poorly developed marketplace for retailing research information to practitioners. A survey in Canada of the four most significant potential retailing groups demonstrated that whereas clinical and community groups were adopting the necessary knowledge and attitudes, public policy makers and administrators trailed well behind them. To increase the probability of thorough retailing of ECPC, a three-phase plan could be instituted that would identify product champions within potential retailing groups, develop implementation activities for each retailing group, and convene annual conferences.

Counseling in the clinical setting to prevent unintended pregnancy: an evidence-based research agenda.

Moos, Merry K; Bartholomew, Neva E; Lohr, Kathleen N

2003-02-01

Unintended pregnancies account for about half of all pregnancies in the United States and, in 1995, numbered nearly 3 million pregnancies. They pose appreciable medical, emotional, social and financial costs on women, their families and society. The US is not attaining national goals to decrease unintended pregnancies, and little is known about effective means for reducing unintended pregnancy rates in adults or adolescents.To examine the evidence about the effectiveness, benefits and harms of counseling in a clinical setting to prevent unintended pregnancy in adults and adolescents and to use the evidence to propose a research agenda.We identified English-language articles from comprehensive searches of the MEDLINE, CINAHL, PsychLit and other databases from 1985 through May 2000; the main clinical search terms included pregnancy (mistimed, unintended, unplanned, unwanted), family planning, contraceptive behavior, counseling, sex counseling, and knowledge, attitudes and behavior. We also used published systematic reviews, hand searching of relevant articles, the second Guide to Clinical Preventive Services and extensive peer review to identify important articles not otherwise found and to assure completeness. Of 673 abstracts examined, we retained 354 for full article review; of these, we used 74 for the systematic evidence review and abstracted data from 13 articles for evidence tables. Four studies addressed the effectiveness of counseling in a clinical setting in changing knowledge, skills and attitudes about contraception and pregnancy; all had poor internal validity and generalizability and collectively did not provide definitive guidance about effective counseling strategies. Nine studies (three in teenage populations) addressed the relationship of knowledge on contraceptive use and adherence. Knowledge of correct contraceptive methods may be positively associated with appropriate use, but reservations about the method itself, partner support of the method

Full Text Available Abstract Background Though cupping therapy has been used in China for thousands of years, there has been no systematic summary of clinical research on it. This review is to evaluate the therapeutic effect of cupping therapy using evidence-based approach based on all available clinical studies. Methods We included all clinical studies on cupping therapy for all kinds of diseases. We searched six electronic databases, all searches ended in December 2008. We extracted data on the type of cupping and type of diseases treated. Results 550 clinical studies were identified published between 1959 and 2008, including 73 randomized controlled trials (RCTs, 22 clinical controlled trials, 373 case series, and 82 case reports. Number of RCTs obviously increased during past decades, but the quality of the RCTs was generally poor according to the risk of bias of the Cochrane standard for important outcome within each trials. The diseases in which cupping was commonly employed included pain conditions, herpes zoster, cough or asthma, etc. Wet cupping was used in majority studies, followed by retained cupping, moving cupping, medicinal cupping, etc. 38 studies used combination of two types of cupping therapies. No serious adverse effects were reported in the studies. Conclusions According to the above results, quality and quantity of RCTs on cupping therapy appears to be improved during the past 50 years in China, and majority of studies show potential benefit on pain conditions, herpes zoster and other diseases. However, further rigorous designed trials in relevant conditions are warranted to support their use in practice.

2017-08-25

Globally, nurses are undertaking expanded and more specialized roles in healthcare planning and service delivery in response to changing patterns and levels of health service demand. This means the nursing profession is increasingly considered as leaders in health service policy, research and practice. The United Arab Emirates has strengthened nursing governance and practice by establishing a Nursing and Midwifery Council and increasing the activity of nursing specialization, service leadership and research. This study aimed to identify clinically relevant research priorities to facilitate nursing contributions to evidence-based care and strengthening health services in the country. A two-stage Delphi study design was used. The first round involved 783 participants. The second round involved 1116 participants, as more clinical settings were accessed. In total, 58 research priorities across a variety of nursing specialties (paediatrics, emergency care, intensive care, labour and maternity care, operating theatre and long-term care) were identified as highly important. These identified priorities will guide a more informed programme of research in each nursing specialty, with the aim of strengthening the evidence base to improving outcomes for patients and their families in the United Arab Emirates. The findings provide guidance on key areas for nurses to focus research contributions to enhance evidence-based care and strengthen health systems. The identified priorities may also guide researchers in academic institutions to conduct research informed by current, clinically relevant issues. The findings may help inform funders and policymakers to support allocation of funding to research that has potential to contribute to enhancing nursing care in specialist areas. © 2017 International Council of Nurses.

The impact of intangibles on the value relevance of accounting information: Evidence from French companies

Directory of Open Access Journals (Sweden)

Bilal Kimouche

2016-03-01

Full Text Available Purpose: The paper aims to explore whether intangible items that recognised in financial statements are value-relevant to investors in the French context, and whether these items affect the value relevance of accounting information. Design/methodology/approach: Empirical data were collected from a sample of French listed companies, over the nine-year period of 2005 to 2013. Starting of Ohlson’s (1995 model, the correlation analysis and the linear multiple regressions have been applied. Findings: We find that intangibles and traditional accounting measures as a whole are value relevant. However, the amortization and impairment charges of intangibles and cash flows do not affect the market values of French companies, unlike other variables, which affect positively and substantially the market values. Also goodwill and book values are more associated with market values than intangible assets and earnings respectively. Finally, we find that intangibles have improved the value relevance of accounting information. Practical implications: French legislators must give more interest for intangibles, in order to enrich the financial statements content and increasing the pertinence of accounting information. Auditors must give more attention for intangibles’ examination process, in order to certify the amounts related to intangibles in financial statements, and hence enrich their reliability, what provides adequacy guarantees for investors to use them in decision making. Originality/value: The paper used recently available financial data, and proposed an improvement concerning the measure of incremental value relevance of intangibles items.

The Relevant Physical Trace in Criminal Investigation

Directory of Open Access Journals (Sweden)

Durdica Hazard

2016-01-01

Full Text Available A criminal investigation requires the forensic scientist to search and to interpret vestiges of a criminal act that happened in the past. The forensic scientist is one of the many stakeholders who take part in the information quest within the criminal justice system. She reads the investigation scene in search of physical traces that should enable her to tell the story of the offense/crime that allegedly occurred. The challenge for any investigator is to detect and recognize relevant physical traces in order to provide clues for investigation and intelligence purposes, and that will constitute sound and relevant evidence for the court. This article shows how important it is to consider the relevancy of physical traces from the beginning of the investigation and what might influence the evaluation process. The exchange and management of information between the investigation stakeholders are important. Relevancy is a dimension that needs to be understood from the standpoints of law enforcement personnel and forensic scientists with the aim of strengthening investigation and ultimately the overall judicial process.

Integrative medicine is the combined use of complementary and alternative medicine with conventional or traditional Western medicine systems. The demand for integrative veterinary medicine is growing, but evidence-based research on its efficacy is limited. In veterinary clinical oncology, such research could be translated to human medicine, because veterinary patients with spontaneous tumors are valuable translational models for human cancers. An overview of specific herbs, botanics, dietary supplements, and acupuncture evaluated in dogs, in vitro canine cells, and other relevant species both in vivo and in vitro is presented for their potential use as integrative therapies in veterinary clinical oncology.

This article starts by providing a brief summary of relevance theory in information science in relation to the function theory of lexicography, explaining the different types of relevance, viz. objective system relevance and the subjective types of relevance, i.e. topical, cognitive, situational...... that is very important for lexicography as well as for information science, viz. functional relevance. Since all lexicographic work is ultimately aimed at satisfying users’ information needs, the article then discusses why the lexicographer should take note of all these types of relevance when planning a new...... dictionary project, identifying new tasks and responsibilities of the modern lexicographer. The article furthermore discusses how relevance theory impacts on teaching dictionary culture and reference skills. By integrating insights from lexicography and information science, the article contributes to new...

Applying research evidence to optimize telehomecare.

Science.gov (United States)

Bowles, Kathryn H; Baugh, Amy C

2007-01-01

Telemedicine is the use of technology to provide healthcare over a distance. Telehomecare, a form of telemedicine based in the patient's home, is a communication and clinical information system that enables the interaction of voice, video, and health-related data using ordinary telephone lines. Most home care agencies are adopting telehomecare to assist with the care of the growing population of chronically ill adults. This article presents a summary and critique of the published empirical evidence about the effects of telehomecare on older adult patients with chronic illness. The knowledge gained will be applied in a discussion regarding telehomecare optimization and areas for future research. The referenced literature in PubMed, MEDLINE, CDSR, ACP Journal Club, DARE, CCTR, and CINAHL databases was searched for the years 1995-2005 using the keywords "telehomecare" and "telemedicine," and limited to primary research and studies in English. Approximately 40 articles were reviewed. Articles were selected if telehealth technology with peripheral medical devices was used to deliver home care for adult patients with chronic illness. Studies where the intervention consisted of only telephone calls or did not involve video or in-person nurse contact in the home were excluded. Nineteen studies described the effects of telehomecare on adult patients, chronic illness outcomes, providers, and costs of care. Patients and providers were accepting of the technology and it appears to have positive effects on chronic illness outcomes such as self-management, rehospitalizations, and length of stay. Overall, due to savings from healthcare utilization and travel, telehomecare appears to reduce healthcare costs. Generally, studies have small sample sizes with diverse types and doses of telehomecare intervention for a select few chronic illnesses; most commonly heart failure. Very few published studies have explored the cost or quality implications since the change in home care

In light of the need to better understand the influence and management of cultural differences among the crewmembers who will live and work in space in the future, the aim of this paper is threefold. First, some of the key research findings on intercultural effectiveness on Earth are presented and their relevance to the functioning of multicultural crews in space is discussed. Second, issues that will need to be addressed in order to maximize the effective functioning of multicultural teams in space are identified. These include improving the procedures for the screening and selection, intercultural training, monitoring and support, and debriefing and re-entry of astronauts and their families. Finally, the paper concludes with the presentation and discussion of some of the key activities that will need to be undertaken to address these issues and, thereby, enhance the overall functioning of multicultural teams living and working in space.

This article presents relevant advances in avian medicine and surgery over the past 5 years. New information has been published to improve clinical diagnosis in avian diseases. This article also describes new pharmacokinetic studies. Advances in the understanding and treatment of common avian disorders are presented in this article, as well. Although important progress has been made over the past years, there is still much research that needs to be done regarding the etiology, pathophysiology, diagnosis, and treatment of avian diseases and evidence-based information is still sparse in the literature.

2016-11-08

The analysis of scientific networks has been applied in health research to map and measure relationships between researchers and institutions, describing collaboration structures, individual roles, and research outputs, and helping the identification of knowledge gaps and cooperation opportunities. Driven by dengue continued expansion in Brazil, we explore the contribution, dynamics and consolidation of dengue scientific networks that could ultimately inform the prioritisation of research, financial investments and health policy. Social network analysis (SNA) was used to produce a 20-year (1995-2014) retrospective longitudinal evaluation of dengue research networks within Brazil and with its partners abroad, with special interest in describing institutional collaboration and their research outputs. The analysis of institutional co-authorship showed a significant expansion of collaboration over the years, increased international involvement, and ensured a shift from public health research toward vector control and basic biomedical research, probably as a reflection of the expansion of transmission, high burden and increasing research funds from the Brazilian government. The analysis identified leading national organisations that maintained the research network connectivity, facilitated knowledge exchange and reduced network vulnerability. SNA proved to be a valuable tool that, along with other indicators, can strengthen a knowledge platform to inform future policy, planning and funding decisions. The paper provides relevant information to policy and planning for dengue research as it reveals: (1) the effectiveness of the research network in knowledge generation, sharing and diffusion; (2) the near-absence of collaboration with the private sector; and (3) the key central organisations that can support strategic decisions on investments, development and implementation of innovations. In addition, the increase in research activities and collaboration has not yet

Harries, U; Elliott, H; Higgins, A

1999-03-01

The UK National Health Service (NHS) R&D strategy acknowledges the importance of developing an NHS where practice and policy is more evidence-based. This paper is based on a qualitative study which aimed to identify factors which facilitate or impede evidence-based policy-making at a local level in the NHS. The study involved a literature review and case studies of social research projects which were initiated by NHS health authority managers or general practitioner (GP) fundholders in one region of the NHS. Data were collected through in-depth interviews with lead policy-makers, GPs and researchers working on each of the case studies and analysis of project documentation. An over-arching theme from the analysis was that of the complexity of R&D in purchasing. The two worlds of research and health services management often sit uncomfortably together. For this reason it was not possible to describe a 'blueprint' for successful R&D, although several important issues emerged. These include sharing an appropriate model for research utilization, the importance of relationships in shaping R&D, the importance of influence and commitment in facilitating evidence-based change, and the resourcing of R&D in purchasing. These issues have important implications for the strategic development of R&D as well as for individual project application. Moving beyond the rhetoric of evidence-based policy-making is more likely if both policy-makers and researchers openly acknowledge this complexity and give due concern to the issues outlined.

Dietary Fiber and the Human Gut Microbiota: Application of Evidence Mapping Methodology

Directory of Open Access Journals (Sweden)

2017-02-01

Full Text Available Interest is rapidly growing around the role of the human gut microbiota in facilitating beneficial health effects associated with consumption of dietary fiber. An evidence map of current research activity in this area was created using a newly developed database of dietary fiber intervention studies in humans to identify studies with the following broad outcomes: (1 modulation of colonic microflora; and/or (2 colonic fermentation/short-chain fatty acid concentration. Study design characteristics, fiber exposures, and outcome categories were summarized. A sub-analysis described oligosaccharides and bacterial composition in greater detail. One hundred eighty-eight relevant studies were identified. The fiber categories represented by the most studies were oligosaccharides (20%, resistant starch (16%, and chemically synthesized fibers (15%. Short-chain fatty acid concentration (47% and bacterial composition (88% were the most frequently studied outcomes. Whole-diet interventions, measures of bacterial activity, and studies in metabolically at-risk subjects were identified as potential gaps in the evidence. This evidence map efficiently captured the variability in characteristics of expanding research on dietary fiber, gut microbiota, and physiological health benefits, and identified areas that may benefit from further research. We hope that this evidence map will provide a resource for researchers to direct new intervention studies and meta-analyses.

Translations of Developmental Screening Instruments: An Evidence Map of Available Research.

Science.gov (United States)

El-Behadli, Ana F; Neger, Emily N; Perrin, Ellen C; Sheldrick, R Christopher

2015-01-01

Children whose parents do not speak English experience significant disparities in the identification of developmental delays and disorders; however, little is known about the availability and validity of translations of developmental screeners. The goal was to create a map of the scientific evidence regarding translations of the 9 Academy of Pediatrics-recommended screening instruments into languages other than English. The authors conducted a systematic search of Medline and PsycINFO, references of identified articles, publishers' Web sites, and official manuals. Through evidence mapping, a new methodology supported by AHRQ and the Cochrane Collaboration, the authors documented the extent and distribution of published evidence supporting translations of developmental screeners. Data extraction focused on 3 steps of the translation and validation process: (1) translation methods used, (2) collection of normative data in the target language, and (3) evidence for reliability and validity. The authors identified 63 distinct translations among the 9 screeners, of which 44 had supporting evidence published in peer-reviewed sources. Of the 63 translations, 35 had at least some published evidence regarding translation methods used, 28 involving normative data, and 32 regarding reliability and/or construct validity. One-third of the translations found were of the Denver Developmental Screening Test. Specific methods used varied greatly across screeners, as did the level of detail with which results were reported. Few developmental screeners have been translated into many languages. Evidence map of the authors demonstrates considerable variation in both the amount and the comprehensiveness of information available about translated instruments. Informal guidelines exist for conducting translation of psychometric instruments but not for documentation of this process. The authors propose that uniform guidelines be established for reporting translation research in peer

Ten steps to conducting health professional education research.

The approaches used to educate future clinicians must be continually improved through evidence-based methods. Clinicians interested in conducting education research need to understand the terminology and conventions of health professional education, in the same way that health professional educators from education backgrounds need to be aware of clinical practices and scientific mores and jargon. This article provides clinicians with 10 steps to conducting health professional education research, and encourages collaboration between clinicians interested in education and health professional educators. The basic steps in conducting education research are introduced, beginning with literature searches, using appropriate terminology and writing conventions, and finding research collaborators. We encourage researchers to ask themselves, 'So what?' about their research idea to ensure it is interesting and relevant to a journal's readers. The nuts and bolts of educational research are then presented, including research questions and methodologies, outcome measures, theoretical frameworks and epistemologies. The final two steps aim to foster internationally relevant and well-designed research studies. Conducting and publishing education research is often difficult for clinicians, who struggle with what is required. Yet clinicians who teach are ideally placed to identify the knowledge gaps about how we can more effectively educate future clinicians. These 10 steps provide clinicians with guidance on how to conduct education research so relevant research findings can inform the education of future clinicians. Conducting and publishing education research is often difficult for clinicians. © 2015 John Wiley & Sons Ltd.

Background For health technology assessment (HTA) to be more policy relevant and for health technology-related decision-making to be truly evidence-based, promoting knowledge translation (KT) is of vital importance. Although some research has focused on KT of HTA, there is a dearth of literature on KT determinants and the situation in developing countries and transitional societies remains largely unknown. Objective To investigate the determinants of HTA KT from research to health policy-making from the perspective of researchers in China. Design Cross-sectional study. Methods A structured questionnaire which focused on KT was distributed to HTA researchers in China. KT activity levels in various fields of HTA research were compared, using one-way ANOVA. Principal component analysis was performed to provide a basis to combine similar variables. To investigate the determinants of KT level, multiple linear regression analysis was performed. Results Based on a survey of 382 HTA researchers, it was found that HTA KT wasn’t widespread in China. Furthermore, results showed that no significant differences existed between the various HTA research fields. Factors, such as attitudes of researchers toward HTA and evidence utilization, academic ranks and linkages between researchers and policy-makers, had significant impact on HTA KT (p-valuespolicy-makers, policy-relevance of HTA research, practicality of HTA outcomes and making HTA reports easier to understand also contributed to predicting KT level. However, academic nature of HTA research was negatively associated with KT level. Conclusion KT from HTA to policy-making was influenced by many factors. Of particular importance were collaborations between researchers and policy-makers, ensuring policy relevance of HTA and making HTA evidence easier to understand by potential users. PMID:29300753

Quality of research and level of evidence in foot and ankle publications.

The quality of research and evidence to support medical treatments is under scrutiny from the medical profession and the public. This study examined the current quality of research and level of evidence (LOE) of foot and ankle surgery papers published in orthopedic and podiatric medical journals. Two independent evaluators performed a blinded assessment of all foot and ankle clinical research articles (January 2010 to June 2010) from seven North American orthopedic and podiatric journals. JBJS-A grading system was used for LOE. Articles were assessed for indicators of study quality. The data was stratified by journal and medical credentials. A total of 245 articles were published, 128 were excluded based on study design, leaving 117 clinical research articles. Seven (6%) were Level I, 14 (12%) Level II, 18 (15%) Level III, and 78 (67%) Level IV. The orthopedic journals published 78 studies on foot and ankle topics. Of the podiatric journals, the Journal of the American Podiatric Medical Association (JAPMA) published 12 clinical studies and the Journal of Foot and Ankle Surgery (JFAS) published 27, 21 (78%) of which were Level IV studies. When the quality of research was examined, few therapeutic studies used validated outcome measures and only 38 of 96 (40%) gathered data prospectively. Thirty (31%) studies used a comparison group. Eighty-seven articles (74%) were authored by a MD and 22 (19%) by a DPM. Foot & Ankle International (FAI) published higher quality studies with a higher LOE as compared to podiatry journals. Regardless of the journal, MDs produced the majority of published clinical foot and ankle research. Although improvements have been made in the quality of some clinical research, this study highlights the need for continued improvement in methodology within foot and ankle literature.

Children's nursing research: toward development, drudgery or demise?

Science.gov (United States)

Long, Tony

This paper, based on a presentation to the UK Association of Chief Children's Nurses, is the author's personal reflection on the nature and future of children's nursing research. Key constitutive elements of this concept are considered to arrive at the conclusion that children's nursing research is research undertaken by children's nurses into questions of relevance to children's nursing practice and services, or wider issues in which children's nursing has a vital role. Three possible futures are presented, of which only the last is positive and desirable: development in line with the reality of practice and population needs. An integrated approach is necessary, with responsibilities both for those in positions of authority in the service and for researchers themselves. In particular, this partnership is essential for children's nursing to evidence the impact of research and for children and young people to reap the greatest benefit from evidence-based practice.

1992-04-01

Electron stripping (ionization) cross sections for impurity (carbon) ions with various charge states in collisions with atomic hydrogens have been surveyed. It has been found that these data are relatively limited both in collision energy and charge state and, in particular those necessary for high energy neutral beam injection (NBI) heating in fusion plasma research are scarce. Some relevant cross sections for carbon ions, C q+ (q = 0-5) have been estimated, based upon the existing data, empirical behavior and electron impact ionization data. (author)

This article reviews the trajectory of our research program on selective attention, which has moved from basic research on the neural processes underlying selective attention to translational studies using selective attention as a neurobiological target for evidence-based interventions. We use this background to present a promising preliminary investigation of how genetic and experiential factors interact during development (i.e., gene × intervention interactions). Our findings provide evidence on how exposure to a family-based training can modify the associations between genotype (5-HTTLPR) and the neural mechanisms of selective attention in preschool children from lower socioeconomic status backgrounds.

Lavis, John N; Oxman, Andrew D; Moynihan, Ray; Paulsen, Elizabeth J

2008-12-17

Organizations have been established in many countries and internationally to support the use of research evidence by producing clinical practice guidelines, undertaking health technology assessments, and/or directly supporting the use of research evidence in developing health policy on an international, national, and state or provincial level. Learning from these organizations can reduce the need to 'reinvent the wheel' and inform decisions about how best to organize support for such organizations, particularly in low- and middle-income countries (LMICs). We undertook a multi-method study in three phases - a survey, interviews, and case descriptions that drew on site visits - and in each of the second and third phases we focused on a purposive sample of those involved in the previous phase. We used the seven main recommendations that emerged from the advice offered in the interviews to organize much of the synthesis of findings across phases and methods. We used a constant comparative method to identify themes from across phases and methods. Seven recommendations emerged for those involved in establishing or leading organizations that support the use of research evidence in developing health policy: 1) collaborate with other organizations; 2) establish strong links with policymakers and involve stakeholders in the work; 3) be independent and manage conflicts of interest among those involved in the work; 4) build capacity among those working in the organization; 5) use good methods and be transparent in the work; 6) start small, have a clear audience and scope, and address important questions; and 7) be attentive to implementation considerations, even if implementation is not a remit. Four recommendations emerged for the World Health Organization (WHO) and other international organizations and networks: 1) support collaborations among organizations; 2) support local adaptation efforts; 3) mobilize support; and 4) create global public goods.

A focus on equity in health can be seen in many global development goals and reports, research and international declarations. With the development of a relevant framework and methods, the Campbell and Cochrane Equity Methods Group has encouraged the application of an 'equity lens' to systematic reviews, and many organizations publish reviews intended to address health equity. The purpose of the Evidence for Equity (E4E) project was to conduct a priority-setting exercise and apply an equity lens by developing a knowledge translation product comprising summaries of systematic reviews from the Cochrane Library. E4E translates evidence from systematic reviews into 'friendly front end' summaries for policy makers. The following topic areas with high burdens of disease globally, were selected for the pilot: diabetes/obesity, HIV/AIDS, malaria, nutrition, and mental health/depression. For each topic area, a "stakeholder panel" was assembled that included policymakers and researchers. A systematic search of Cochrane reviews was conducted for each area to identify equity-relevant interventions with a meaningful impact. Panel chairs developed a rating sheet which was used by all panels to rank the importance of these interventions by: 1) Ease of Implementation; 2) Health System Requirements; 3)Universality/Generalizability/Share of Burden; and 4) Impact on Inequities/Effect on equity. The ratings of panel members were averaged for each intervention and criterion, and interventions were ordered according to the average overall ratings. Stakeholder panels identified the top 10 interventions from their respective topic areas. The evidence on these interventions is being summarized with an equity focus and the results posted online, at http://methods.cochrane.org/equity/e4e-series . This method provides an explicit approach to setting priorities by systematic review groups and funders for providing decision makers with evidence for the most important equity-relevant

Solidarity with Animals: Assessing a Relevant Dimension of Social Identification with Animals.

Amiot, Catherine E; Bastian, Brock

2017-01-01

Interactions with animals are pervasive in human life, a fact that is reflected in the burgeoning field of human-animal relations research. The goal of the current research was to examine the psychology of our social connection with other animals, by specifically developing a measure of solidarity with animals. In 8 studies using correlational, experimental, and longitudinal designs, solidarity with animals predicted more positive attitudes and behaviors toward animals, over and above existing scales of identification, and even when this implied a loss of resources and privileges for humans relative to animals. Solidarity with animals also displayed predicted relationships with relevant variables (anthropomorphism, empathy). Pet owners and vegetarians displayed higher levels of solidarity with animals. Correlational and experimental evidence confirmed that human-animal similarity heightens solidarity with animals. Our findings provide a useful measure that can facilitate important insights into the nature of our relationships with animals.

Single-Case Design Research: Building the Evidence-Base in the Field of Education of Deaf and Hard of Hearing Students.

Cannon, Joanna E; Guardino, Caroline; Antia, Shirin D; Luckner, John L

2016-01-01

The field of education of deaf and hard of hearing (DHH) students has a paucity of evidence-based practices (EBPs) to guide instruction. The authors discussed how the research methodology of single-case design (SCD) can be used to build EBPs through direct and systematic replication of studies. An overview of SCD research methods is presented, including an explanation of how internal and external validity issues are addressed, and why SCD is appropriate for intervention research with DHH children. The authors then examine the SCD research in the field according to quality indicators (QIs; at the individual level and as a body of evidence) to determine the existing evidence base. Finally, future replication areas are recommended to fill the gaps in SCD research with students who are DHH in order to add to the evidence base in the field.

Evidence in clinical reasoning: a computational linguistics analysis of 789,712 medical case summaries 1983-2012.

Seidel, Bastian M; Campbell, Steven; Bell, Erica

2015-03-21

Better understanding of clinical reasoning could reduce diagnostic error linked to 8% of adverse medical events and 30% of malpractice cases. To a greater extent than the evidence-based movement, the clinical reasoning literature asserts the importance of practitioner intuition—unconscious elements of diagnostic reasoning. The study aimed to analyse the content of case report summaries in ways that explored the importance of an evidence concept, not only in relation to research literature but also intuition. The study sample comprised all 789,712 abstracts in English for case reports contained in the database PUBMED for the period 1 January 1983 to 31 December 2012. It was hypothesised that, if evidence and intuition concepts were viewed by these clinical authors as essential to understanding their case reports, they would be more likely to be found in the abstracts. Computational linguistics software was used in 1) concept mapping of 21,631,481 instances of 201 concepts, and 2) specific concept analyses examining 200 paired co-occurrences for 'evidence' and research 'literature' concepts. 'Evidence' is a fundamentally patient-centred, intuitive concept linked to less common concepts about underlying processes, suspected disease mechanisms and diagnostic hunches. In contrast, the use of research literature in clinical reasoning is linked to more common reasoning concepts about specific knowledge and descriptions or presenting features of cases. 'Literature' is by far the most dominant concept, increasing in relevance since 2003, with an overall relevance of 13% versus 5% for 'evidence' which has remained static. The fact that the least present types of reasoning concepts relate to diagnostic hunches to do with underlying processes, such as what is suspected, raises questions about whether intuitive practitioner evidence-making, found in a constellation of dynamic, process concepts, has become less important. The study adds support to the existing corpus of

Musculoskeletal disorders as a fatigue failure process: evidence, implications and research needs.

Science.gov (United States)

Gallagher, Sean; Schall, Mark C

2017-02-01

Mounting evidence suggests that musculoskeletal disorders (MSDs) may be the result of a fatigue failure process in musculoskeletal tissues. Evaluations of MSD risk in epidemiological studies and current MSD risk assessment tools, however, have not yet incorporated important principles of fatigue failure analysis in their appraisals of MSD risk. This article examines the evidence suggesting that fatigue failure may play an important role in the aetiology of MSDs, assesses important implications with respect to MSD risk assessment and discusses research needs that may be required to advance the scientific community's ability to more effectively prevent the development of MSDs. Practitioner Summary: Evidence suggests that musculoskeletal disorders (MSDs) may result from a fatigue failure process. This article proposes a unifying framework that aims to explain why exposure to physical risk factors contributes to the development of work-related MSDs. Implications of that framework are discussed.

Healthy Variability in Organizational Behavior: Empirical Evidence and New Steps for Future Research.

Navarro, José; Rueff-Lopes, Rita

2015-10-01

The healthy variability thesis suggests that healthy systems function in a complex manner over time. This thesis is well-established in fields like physiology. In the field of organizational behavior, however, this relation is only starting to be explored. The objective of this article is threefold: First, we aim to provide a comprehensive review of the healthy variability thesis including some of the most important findings across different fields, with a focus on evidences from organizational research in work motivation and performance. Second, we discuss an opposite pattern, unhealthy stability, i.e., the relationship between unhealthy behaviors and lower variability. Again, we provide evidence from diverse areas, from affective processes to disruptive organizational comportments like mobbing. Third, we provide a critical evaluation of current methodological trends and highlight what we believe to be the main factors that are stopping organizational research from advancing in the field. Theoretical, methodological and epistemological implications are discussed. To conclude, we draw a compilation of the lessons learned, which hopefully provide insights for prolific research avenues. Our main purpose is to raise awareness of the healthy variability thesis and to enthuse organizational researchers to consider it in order to advance existing knowledge, revisit old theories and create new ones.

Scientific research can contribute to more efficient health care, enhance care quality and safety of persons. In order for this to happen, the knowledge gained must be put into practice. Implementation is known as the introduction of a change or innovation to daily practice, which requires effective communication and the elimination of barriers that hinder this process. Best practice implementation experiences are being used increasingly in the field of nursing. The difficulty in identifying the factors that indicate the success or failure of implementation has led to increased studies to build a body of differentiated knowledge, recognized as implementation science or implementation research. Implementation research is the scientific study whose objective is the adoption and systematic incorporation of research findings into clinical practice to improve the quality and efficiency of health services. The purpose of implementation research is to improve the health of the population through equitable and effective implementation of rigorously evaluated scientific knowledge, which involves gathering the evidence that has a positive impact on the health of the community. In this text, we set out the characteristics of nursing implementation research, providing a synthesis of different methods, theories, key frameworks and implementation strategies, along with the terminology proposed for greater conceptual clarity.

Science-based occupations and the science curriculum: Concepts of evidence

Science.gov (United States)

Aikenhead, Glen S.

2005-03-01

What science-related knowledge is actually used by nurses in their day-to-day clinical reasoning when attending patients? The study investigated the knowledge-in-use of six acute-care nurses in a hospital surgical unit. It was found that the nurses mainly drew upon their professional knowledge of nursing and upon their procedural understanding that included a common core of concepts of evidence (concepts implicitly applied to the evaluation of data and the evaluation of evidence - the focus of this research). This core included validity triangulation, normalcy range, accuracy, and a general predilection for direct sensual access to a phenomenon over indirect machine-managed access. A cluster of emotion-related concepts of evidence (e.g. cultural sensitivity) was also discovered. These results add to a compendium of concepts of evidence published in the literature. Only a small proportion of nurses (one of the six nurses in the study) used canonical science content in their clinical reasoning, a result consistent with other research. This study also confirms earlier research on employees in science-rich workplaces in general, and on professional development programs for nurses specifically: canonical science content found in a typical science curriculum (e.g. high school physics) does not appear relevant to many nurses' knowledge-in-use. These findings support a curriculum policy that gives emphasis to students learning how to learn science content as required by an authentic everyday or workplace context, and to students learning concepts of evidence.

Nutrition and age-related macular degeneration: research evidence in practice.

Downie, Laura Elizabeth; Keller, Peter Richard

2014-08-01

Age-related macular degeneration (AMD) is the leading cause of irreversible visual impairment in developed countries. In the absence of effective treatments to slow AMD progression, it is predicted that the prevalence of AMD will double over the next 20 years. One area of significant interest is the potential role that nutrition may play in preventing and/or delaying the progression of AMD. Specifically, is there any benefit in oral antioxidant and/or mineral supplementation? This review critically evaluates the currently available evidence relating to nutrition and AMD, with particular reference to the key findings of two large National Eye Institute-sponsored clinical studies, namely, the Age-Related Eye Disease Study (AREDS) and AREDS2. Topical controversies relating to nutrition and AMD are considered and analyzed in the context of the published literature to guide practitioners through assessing the merit, or otherwise, of common claims. This article provides a foundation for clinicians to provide informed advice to AMD patients based on available research evidence.

Enhanced fear learning for fear-relevant stimuli has been demonstrated in procedures with adults in the laboratory. Three experiments investigated the effect of stimulus fear-relevance on vicarious fear learning in children (aged 6-11 years). Pictures of stimuli with different levels of fear-relevance (flowers, caterpillars, snakes, worms, and Australian marsupials) were presented alone or together with scared faces. In line with previous studies, children's fear beliefs and avoidance preferences increased for stimuli they had seen with scared faces. However, in contrast to evidence with adults, learning was mostly similar for all stimulus types irrespective of fear-relevance. The results support a proposal that stimulus preparedness is bypassed when children observationally learn threat-related information from adults.

A growing body of research evidence has confirmed the efficacy of family-interventions as adjuncts to antipsychotics for the treatment of schizophrenia. Much of the recent evidence for such interventions derives from Asian, principally Chinese, studies. These trials have shown that relatively simple forms of family-interventions have wide ranging benefits, and can be implemented successfully in routine clinical settings. With the accumulation of this evidence in their favour, family-interventions for schizophrenia in Asia are poised to take the next critical step, that of wider implementation and improved accessibility for potential users. However, several issues merit consideration. Family-interventions need to be based on a culturally-informed theory, which incorporates cultural variables of relevance in these countries. While the ideal format for conducting family-interventions is still to be determined, it is quite evident that for such interventions to be useful they need to be simple, inexpensive, needs-based, and tailored to suit the socio-cultural realities of mental health systems in Asian countries. The evidence also suggests that delivery by non-specialist personnel is the best way to ensure that such services reach those who stand to benefit most from these treatments. However, there are several existing challenges to the process of dissemination of family-interventions. The major challenges include the achievement of a critical mass of trained professionals capable of delivering these interventions, and finding innovative solutions to make family-interventions more acceptable to families. If these hurdles are overcome, we could look forward to a genuine collaboration with families, who have always been the mainstay of care for the mentally ill in Asia.

Full Text Available Introduction: Evidence-based practice (EBP is the conscientious, explicit and judicious use of the current evidence in clinical decision making. The physiotherapy profession has expressed a commitment to the development and use of evidence. However, very little is known about the extent to which EBP is integrated in physiotherapy curricula in India. The purpose of this study was to describe integration of EBP in Indian physiotherapy programs. Methods: An observational study was conducted where a review of curricula of all Health Science Universities (HSU in India, offering an undergraduate (UG and post-graduate (PG degree program in physical therapy was conducted using a data abstraction sheet. It gathered data on inclusion of research components of EBP in the curricula, content and hours of teaching EBP, and assessment methods. Data were analyzed descriptively. Results: Curricula of fifteen HSU offering physiotherapy programs were reviewed. Contents relevant to EBP were incorporated from the 2nd yr to final year. Common courses included research methodology (84.61%, research project (69.23% and clinical management subjects (57.14%. No guidelines were given about adopting EBP in clinical practice. Didactic lectures were the mode of teaching (81.81%. Preferred method for assessing research projects was viva (44.44%. Critical appraisal was least included in the entry level education. Contents relevant to all the five steps of EBP were included in PG curricula. Conclusions: Though physiotherapy programs are introducing EBP teaching at the entry level, it lacks structured systematic approach and is fragmented. There is inadequate emphasis on clinical oriented teaching of EBP and assessment methods. Moreover, there is adequate coverage of EBP content in PG curricula.

Relevance of collagen piezoelectricity to "Wolff's Law": a critical review.

According to "Wolff's Law", bone is deposited and reinforced at areas of greatest stress. From a clinical perspective, this "law" is supported by the strong association between bone density and physical activity. From a mechanistic standpoint, however, the law presents a challenge to scientists seeking to understand how osteocytes and osteoblasts sense the mechanical load. In the 1960s, collagen piezoelectricity was invoked as a potential mechanism by which osteocytes could detect areas of greater stress but piezoelectricity diminished in importance as more compelling mechanisms, such as streaming potential, were identified. In addition, accumulating evidence for the role of fluid-related shear stress in osteocyte's mechanosensory function has made piezoelectricity seemingly more obsolete in bone physiology. This review critically evaluates the role of collagen piezoelectricity (if any) in Wolff's Law--specifically, the evidence regarding its involvement in strain-generated potentials, existing alternate mechanisms, the present understanding of bone mechanosensation, and whether piezoelectricity serves an influential role within the context of this newly proposed mechanism. In addition to reviewing the literature, this review generates several hypotheses and proposes future research to fully address the relevance of piezoelectricity in bone physiology.

The present study explored the ability of expert and novice chess players to rapidly distinguish between regions of a chessboard that were relevant to the best move on the board, and regions of the board that were irrelevant. Accordingly, we monitored the eye movements of expert and novice chess players, while they selected white's best move for a variety of chess problems. To manipulate relevancy, we constructed two different versions of each chess problem in the experiment, and we counterbalanced these versions across participants. These two versions of each problem were identical except that a single piece was changed from a bishop to a knight. This subtle change reversed the relevancy map of the board, such that regions that were relevant in one version of the board were now irrelevant (and vice versa). Using this paradigm, we demonstrated that both the experts and novices spent more time fixating the relevant relative to the irrelevant regions of the board. However, the experts were faster at detecting relevant information than the novices, as shown by the finding that experts (but not novices) were able to distinguish between relevant and irrelevant information during the early part of the trial. These findings further demonstrate the domain-related perceptual processing advantage of chess experts, using an experimental paradigm that allowed us to manipulate relevancy under tightly controlled conditions.

Full Text Available An accident depends on a lot of factors and circumstances. The estabilishment of factors, different evidences and circumstances are very important for research. Some important evidences are fixed when we make photos, do the the measurements of the deformation of means of transport, do the measurements of sliding and of stopping, estimate the condition of road and weather, driver’s and pedestrian’s actions, do cross-examination of witnesses and so on. We often have no result even if we know the main circumstances of the accident. So we need some engineer countings for the modelling of various situations. The method of linear momentum is presented in this article. It is used for the counting of parameters of accidents. The accident diagram gives information for us. We can do the research of an accident with the help of this method and software. So the research into the collision of cars was done with the help of this method and software.

Health systems worldwide struggle to identify, adopt, and implement in a timely and system-wide manner the best-evidence-informed-policy-level practices. Yet, there is still only limited evidence about individual and institutional best practices for fostering the use of scientific evidence in policy-making processes The present project is the first national-level attempt to (1) map and structurally analyze-quantitatively-health-relevant policy-making networks that connect evidence production, synthesis, interpretation, and use; (2) qualitatively investigate the interaction patterns of a subsample of actors with high centrality metrics within these networks to develop an in-depth understanding of evidence circulation processes; and (3) combine these findings in order to assess a policy network's "absorptive capacity" regarding scientific evidence and integrate them into a conceptually sound and empirically grounded framework. The project is divided into two research components. The first component is based on quantitative analysis of ties (relationships) that link nodes (participants) in a network. Network data will be collected through a multi-step snowball sampling strategy. Data will be analyzed structurally using social network mapping and analysis methods. The second component is based on qualitative interviews with a subsample of the Web survey participants having central, bridging, or atypical positions in the network. Interviews will focus on the process through which evidence circulates and enters practice. Results from both components will then be integrated through an assessment of the network's and subnetwork's effectiveness in identifying, capturing, interpreting, sharing, reframing, and recodifying scientific evidence in policy-making processes. Knowledge developed from this project has the potential both to strengthen the scientific understanding of how policy-level knowledge transfer and exchange functions and to provide significantly improved advice

Full Text Available Many researchers worked a lot on geologic conditions for lateral sealing of faults, but none of their studies took the effect of internal structures of fault zones on the lateral sealing capacity of faults. Therefore, the lateral sealing of active faults has rarely been discussed. In this paper, based on the analysis of the composition and structure characteristics of fault fillings, the geological conditions for lateral sealing of active faults and relevant research method were discussed in reference to the lateral sealing mechanisms of inactive fault rocks. It is shown that, in order to satisfy geologically the lateral sealing of active faults, the faults should be antithetic and the faulted strata should be mainly composed of mudstone, so that the displacement pressure of fault fillings is higher than or equal to that of reservoir rocks in oil and gas migration block. Then, a research method for the lateral sealing of active faults was established by comparing the displacement pressure of fillings in the fault with that of reservoir rocks in oil and gas migration block. This method was applied to three antithetic faults (F1, F2 and F3 in No. 1 structure of the Nanpu Sag, Bohai Bay Basin. As revealed, the fillings of these three active faults were mostly argillaceous at the stage of natural gas accumulation (the late stage of Neogene Minghuazhen Fm sedimentation, and their displacement pressures were higher than that of reservoir rocks in the first member of Paleogene Dongying Fm (F1 and F3 and the Neogene Guantao Fm (F2. Accordingly, they are laterally sealed for natural gas, which is conducive to the accumulation and preservation of natural gas. Industrial gas flow has been produced from the first member of Paleogene Dongying Fm in Well Np101, the Guantao Fm in Well Np1-2 and the first member of Paleogene Dongying Fm in Well Np1, which is in agreement with the analysis result. It is verified that this method is feasible for investigating the
