Evidence Based Practice (chapter 5) Flashcards
Step 1 of EBP
Formulating the Clinical or Research Q
Step 2 of EBP
Searching for the evidence
Step 3 of EBP
Evaluating the evidence
Part A of Step 3
Determine the level of evidence
Part B of Step 3
Rate the risk of bias of the evidence
Part C of Step 3
Grade the cliical recommendation under consideration
Step 4 of EBP
Integrating Scientific Evidence,
Clinical Expertise, and
Patient Preferences into Clinical Decision-Making
Step 5
Evaluating the Process
PICO stands for
Population
Intervention
Comparison (intervention)
Outcome
PICO
a helpful procedure in framing research questions
Most rigorous class level of evidence
Class I
Least rigorous class level of evidence
Class VI
Two types of variables in an experiment
independent & dependent
Independent variables
manipulated by the experimenter who is trying to test a hypothesis
Dependent variable
The one that is measured
Treatment/intervention
Refer to applications or procedures that health professionals administer to lessen the effects of, or cure, a disease or a disorder.
Placebo
inactive medications or procedures that are administered the same exact way as the experimental treatment and serve as a comparison
Class I
Well-designed systematic reviews with meta-analysis of more than one double-blinded, randomized, controlled clinical trial
Class I research methods
May involve either primary measurement methods or secondary measurement methods
Primary measurement methods
involve investigators collecting and analyzing their own data for a single experiment
Secondary measurement methods
Involve investigators experimenters or clinicians considering or analyzing data collected in one or more studies conducted by other investigators
Example of secondary measurement methods
Conducting a systematic review of the evidence assessing the effectiveness of a particular diagnostic procedure or treatment of hearing impairment
Systematic reviews
Can be a qualitative review of the evidence or quantitative review
quantitative review
Involves a meta-analysis, or the use of special statistical procedures that combine the results of more than one investigation in order to measure the magnitude of a treatment effect.
systematic review with meta-analysis
Permits the the combining of the results of several studies together to increase the magnitude of the effect of the study
Effect size
a special metric that determines the degree of impact of significant findings
