week 3- finding and appraising literature Flashcards
What are the steps to evidence informed practice?
- Ask clinical question
- Collect the best evidence (systematic review)
- Critique the evidence
- Integrate the evidence
- Evaluate the practice change or decision (quality assurance)
What are the Boolean phrases used in searching?
and, or, not
What are wild cards in searching?
- matches multiple characters, usually at the end of a word (ie. nurs* = nurse, nursing, nurses)
# matches one optional character, typically when an alternate spelling contains an extra letter (ie. p#ediatric = pediatric, paedeatric)
? matches exactly one letter within a word (ie. ne?t = next, nest, neat)
What is a primary source?
Articles and books by the original author, written during the time of observation by the person who made the observations.
Example: research study.
What is a secondary source?
Articles or books written by people other than the individual who developed the theory or conducted the research study. It includes summaries, critiques, and analyses.
What is a systematic review?
Used rigorous methods to identify, critically appraise, and synthesize primary studies. It involves exhaustive searching with inclusion/exclusion criteria and can provide a summary on what is known on a topic.
What is a literature review?
Both a summary and explanation of the current state of knowledge on a focused topic. It aims to provide an overview of sources explored while researching a particular topic.
What is the purpose of a literature review?
Provides the foundation for the study, summarizes current knowledge, uncovers gaps/inconsistencies, and exposes strengths and weaknesses of previous studies.
What is the researcher’s purpose?
To learn what is known/unknown about a subject, determine gaps, create research questions, and assess if existing studies need to be repeated or refined.
What should be evaluated in a literature review?
Identified gaps, how the study addresses the gap, whether references are primary or secondary sources, and if definitions and variables are articulated.
What are best practice guidelines (BPGs)?
Systematically developed statements to assist health care workers in making appropriate decisions about specific clinical circumstances, based on research evidence.
Why should we use BPGs?
They reduce variation in care, transfer research evidence into practice, promote nursing knowledge, assist with clinical decision making, and identify gaps in research.
How are BPGs created?
- Topic selection
- Panel of experts assembled
- Systematic review
- Recommendations formed/guideline created
- Stakeholder review
- Publication
- Five year guideline review
What is a scoping review?
A preliminary assessment of research to identify the nature and extent of evidence.
What is a meta-analysis?
A statistical technique that combines results of quantitative studies.
What is an umbrella review?
An overarching review to aggregate findings from several reviews.
