Evidence-based practice is defined as "a problem solving approach to clinical decision making that incorporates a search for the best and latest evidence, clinical expertise and assessment, and patient preferences and values within a context of caring." One way to organize the different types of evidence involved in evidence-based practice research is the levels of evidence pyramid. Evidence: The team searches, appraises, rates the strength of evidence, describes quality of evidence, and makes a practice recommendation on the strength of evidence. This hierarchy is widely used in discussions about the quality of medical studies and is integrated into the grading of evidence in practice guidelines.1However, although the pyr… For study types that are not listed as a “Publication Type” search the “CINAHL Headings” for the study type. • Guide for finding the best evidence quickly and efficiently.

Each level was achieved different results. Source: UIC Evidence Based Practice Tutorial, ebp.lib.uic.edu The first and earliest principle of evidence-based medi- cine indicated that a hierarchy of evidence exists. In this construct, different study designs are considered in the context of a pyramid of evidence, in which studies most susceptible to threats to internal validity reside at the bottom and those least prone reside at the top (Figure). The top of the pyramid, Level 1, represents the strongest evidence. Searching for Evidence Pyramid: Basic MetaSearch Engines ex. First, levels of evidence provide only a rough guide to study quality. Evidence Pyramid - Levels of Evidence Evidence Pyramid. (Melnyk, 2004) The weakest level of evidence is the opinion from authorities and/or reports of expert committees.

This evidence encompasses all facets of healthcare, and includes decisions related to the care of an individual, an organization or at the policy level. The evidence higherarchy allows you to take a top-down approach to locating the best evidence whereby you first search for a recent well-conducted systematic review and if that is not available, then move down to the next level of evidence to answer your question. A hierarchy of evidence (or levels of evidence) is a heuristic used to rank the relative strength of results obtained from scientific research. Evidence-based medicine strives to make health-related decisions based on the best available evidence. The search was based on the hierarchy of evidence pyramid. Melnyk, B.M. Assignment 2.

In the early 2000s, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group developed a framework in which the certainty in evidence was based on numerous factors and not solely on study design which challenges the pyramid concept.8 Study design alone appears to be insufficient on its own as a surrogate for risk of bias. (Hoffman, 2013) Hoffman, T., Bennett, S., & DelMar, C.
