FYI 5
Clinicians must decide to adopt or reject innovations through reducing the uncertainty of an innovation. one strategy that individuals use to reduce uncertainty during the decision-making process is to try a portion of the innovation or adopt the innovation on a trial basis, which is called a pilot
Trip Database

FYI 6
There are five steps for evaluating and implementing EBP: ask, acquire, appraise, apply and assess. nurses need to examine all the evidence to make recommendations about practice changes.

FYI 7
Various professional associations and other clinical entities have developed CPGs to be used in practice settings. CPGs will continue evolving because of the momentum generated by EBP, and they will become more available because of the increased capacity to search the literature through computerization

FYI 1
an organized framework, or pyramid of evidence, explains the importance and contribution of various levels of information of evidence-based healthcare delivery. the pyramid of evidence has five levels, known as the 5 s's: studies, syntheses, synopses, summaries, and systems
Domain 5 (domains of quality in the AGREE II instrument)
applicability addresses the behavioral, cost, and organizational consequences of applying the guideline
adoption
applying an innovation to practice
AGREE II
appraisal of Guidelines Research and Evaluation; Internationally developed instrument to evaluate clinical practice guidelines
traditional literature review
article based on common or uncommon elements of works with little concern for research methods, designs, or settings; narrative literature review
FYI 3
because the purpose of EBP is to answer clinical questions, and the oil is to efficiently find information, nurses should begin the search for information at the top of the pyramid and work down the various levels. the best option is having a system already in place that brings the information to the medical record.
Domain 4 (domains of quality in the AGREE II instrument)
clarity and presentation evaluates the format and clearness of the guideline
appraise (five-step approach for EBNP)
conduct a critical appraisal of the literature and studies. evaluate for validity and determine the applicability in practice

assess (five-step approach for EBNP)
evaluate the application for the findings, outcomes and relevance to nursing practice.
prognosis (common critical questions)
evaluates the course of treatment over time, any complications, and overall prognosis
therapy (common critical questions)
examines therapeutic treatment(s) for healthcare problems and their efficacy, cost and potential harm
randomized controlled trials
experimental suites that typically involve large samples and are conducted in multiple sites
consistency
for any given topic, the extent to which similar findings are reported using similar and different study designs
FYI 4
fortunately, few ethical dilemmas arise when considering use of evidence. when nurses find evidence that can be applied to practice, they must consider changes carefully because lives are at stake; however, it is unethical not to a adopt practice guidelines when the evidence is clear.

FYI 8
nurses who engage in activities that promote EBP, such as journals clubs and policy committees, may find even after diligently reviewing the evidence, practice changes are not implemented. nurses need to follow agency policy and act as change agents to effectively bring the evidence to the point of care.
