Evidence-based
Evidence-based practice (EBP) is the idea that occupational practices ought to be based on scientific evidence. While seemingly obviously desirable, the proposal has been controversial, with some arguing that results may not specialize to individuals as well as traditional practices. Evidence-based practices have been gaining ground since the formal introduction of evidence-based medicine in 1992 and have spread to the allied health professions, education, management, law, public policy, architecture, and other fields. In light of studies showing problems in scientific research (such as the replication crisis), there is also a movement to apply evidence-based practices in scientific research itself. Research into the evidence-based practice of science is called metascience. The movement towards evidence-based practices attempts to encourage and, in some instances, require professionals and other decision-makers to pay more attention to evidence to inform their decision-making.

Evidence-based Medicine
Evidence-based medicine (EBM) is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients". The aim of EBM is to integrate the experience of the clinician, the values of the patient, and the best available scientific information to guide decision-making about clinical management. The term was originally used to describe an approach to teaching the practice of medicine and improving decisions by individual physicians about individual patients. Background, history and definition Medicine has a long history of scientific inquiry about the prevention, diagnosis, and treatment of human disease. The concept of a controlled clinical trial was first described in 1662 by Jan Baptist van Helmont in reference to the practice of bloodletting. Wrote Van Helmont: The first published report describing the conduct and results of a controlled clinical trial was by James Lind, a Scottish naval surgeon who conducted rese ...

Evidence-based Policy
Evidence-based policy is an idea in public policy proposing that policy decisions should be based on, or informed by, rigorously established objective evidence. The implied contrast is with policymaking based on ideology, 'common sense,' anecdotes, and intuitions. It is the government equivalent of the effective altruism movement. Evidence-based policy uses a thorough research method, such as randomized controlled trials (RCT). Good data, analytical skills, and political support to the use of scientific information are typically seen as the crucial elements of an evidence-based approach. Some have promoted particular types of evidence as 'best' for policymakers to consider, including scientifically rigorous evaluation studies such as randomized controlled trials to identify programs and practices capable of improving policy-relevant outcomes. However, some areas of policy-relevant knowledge may not be well served by quantitative research. This has led to a debate about the ty ...

Evidence-based Education
Evidence-based education (EBE) is the principle that education practices should be based on the best available scientific evidence, rather than tradition, personal judgement, or other influences. Evidence-based education is related to evidence-based teaching, evidence-based learning, and school effectiveness research. For example, research has shown that spaced repetition (also spaced training, spacing effect and spaced learning) "leads to more robust memory formation than does massed training, which involves short or no intervals". The evidence-based education movement has its roots in the larger movement towards evidence-based practices, and has been the subject of considerable debate since the late 1990s. However, research published in 2020 showed that there is still widespread belief, amongst educators in ineffective teaching techniques such as matching instruction to so-called learning styles and the cone of learning.

Evidence-based Management
Evidence-based management (EBMgt) is an emerging movement to explicitly use the current, best evidence in management and decision-making. It is part of the larger movement towards evidence-based practices. Overview Evidence-based management entails managerial decisions and organizational practices informed by the ''best available'' evidence. As with other evidence-based practice, this is based on the three following principles: * 1) published peer-reviewed (often in management or social science journals) research evidence that bears on whether and why a particular management practice works; * 2) judgement and experience from contextual management practice, to understand the organization and interpersonal dynamics in a situation and determine the risks and benefits of available actions; * 3) the preferences and values of those affected. While, like its counterparts in medicine, and education EBMgt considers the circumstances and ethical concerns managerial decisions involve, it t ...

Hierarchy Of Evidence
A hierarchy of evidence (or levels of evidence) is a heuristic used to rank the relative strength of results obtained from scientific research. There is broad agreement on the relative strength of large-scale, epidemiological studies. More than 80 different hierarchies have been proposed for assessing medical evidence. The design of the study (such as a case report for an individual patient or a blinded randomized controlled trial) and the endpoints measured (such as survival or quality of life) affect the strength of the evidence. In clinical research, the best evidence for treatment efficacy is mainly from meta-analyses of randomized controlled trials (RCTs). Systematic reviews of completed, high-quality randomized controlled trials – such as those published by the Cochrane Collaboration – rank the same as systematic review of completed high-quality observational studies in regard to the study of side effects. Evidence hierarchies are often applied in evidence-based practic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gordon Guyatt
Gordon Henry Guyatt (born November 11, 1953) is a Canadian physician who is Distinguished University Professor in the Departments of Health Research Methods, Evidence and Impact (formerly Clinical Epidemiology & Biostatistics) and Medicine at McMaster University in Hamilton, Ontario. He is known for his leadership in '' evidence-based medicine'', a term that first appeared in a single-author paper he published in 1991. Subsequently, a 1992 ''JAMA'' article that Guyatt led proved instrumental in bringing the concept of evidence-based medicine to the world's attention. /sup> In 2007, ''The BMJ ''launched an international election for the most important contributions to healthcare. Evidence-based medicine came 7th, ahead of the computer and medical imaging. 4] Guyatt's concerns with the role of the medical system, social justice, and medical reform remain central issues that he promoted in tandem with his medical work. On October 9, 2015, he was named to the Canadian Medical Hall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meta-analysis
A meta-analysis is a statistical analysis that combines the results of multiple scientific studies. Meta-analyses can be performed when there are multiple scientific studies addressing the same question, with each individual study reporting measurements that are expected to have some degree of error. The aim then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived. Meta-analytic results are considered the most trustworthy source of evidence by the evidence-based medicine literature.Herrera Ortiz AF., Cadavid Camacho E, Cubillos Rojas J, Cadavid Camacho T, Zoe Guevara S, Tatiana Rincón Cuenca N, Vásquez Perdomo A, Del Castillo Herazo V, & Giraldo Malo R.

Systematic Review
A systematic review is a Literature review, scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. A systematic review extracts and interprets data from published studies on the topic, then analyzes, describes, and summarizes interpretations into a refined conclusion. For example, a systematic review of randomized controlled trials is a way of summarizing and implementing evidence-based medicine. While a systematic review may be applied in the Biomedical research, biomedical or health care context, it may also be used where an assessment of a precisely defined subject can advance understanding in a field of research. A systematic review may examine clinical tests, public health interventions, environmental interventions, social interventions, adverse effects, qualitative evidence syntheses, methodological reviews, policy reviews, and economic evaluations. An understanding of systematic review ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Randomized Controlled Trials
A randomized controlled trial (or randomized control trial; RCT) is a form of scientific experiment used to control factors not under direct experimental control. Examples of RCTs are clinical trials that compare the effects of drugs, surgical techniques, medical devices, diagnostic procedures or other medical treatments. Participants who enroll in RCTs differ from one another in known and unknown ways that can influence study outcomes, and yet cannot be directly controlled. By randomly allocating participants among compared treatments, an RCT enables ''statistical control'' over these influences. Provided it is designed well, conducted properly, and enrolls enough participants, an RCT may achieve sufficient control over these confounding factors to deliver a useful comparison of the treatments studied. Definition and examples An RCT in clinical research typically compares a proposed new treatment against an existing standard of care; these are then termed the 'experimental' a ...

Evidence-based Legislation
Evidence-based legislation (EBL) is a legislative concept which calls for the use of the best available scientific evidence and systematically collected data, when available, by legislatures as a basis for their formulation and writing of law. Evidence-based legislation has its roots in the larger movement towards evidence-based practices, and depends on multiple other factors, including evidence gathering, qualitative and quantitative data analyses, stakeholder assessments, expert input, cost-benefit analyses, and continued monitoring and equation. Overview This concept was originally mentioned at a conference entitled "At the Margins. A Conference on Sex Offender Management in Minnesota 2006. Policy and Management Options for the Most Dangerous Sex Offenders" by Gerald T. Kaplan, a psychologist. This conference was organized by Eric Janus, Esq. Vice-Dean, the William Mitchell College of Law, and was held on February 24, 2006, in Minneapolis, Minnesota. The conference was devote ...
