Evidence-based Practice & Introduction to Quantitative Research Flashcards
What is the accepted definition of EBP?
The integration of the best available research evidence with clinical expertise and the patient’s unique values and circumstances.
What are the three key sources of information integrated in Evidence-Based Practice?
1) Clinical expertise and experience
2) Patients’ values, preferences, and circumstances
3) Best available scientific evidence.
How did Evidence-Based Practice (EBP) originate, and which fields has it expanded to?
Evidence-Based Practice (EBP) originated in medicine as Evidence-Based Medicine (EBM) and has since expanded to fields such as nursing, psychology, education, and information services.
In Evidence-Based Practice, what does clinical expertise and experience encompass?
Clinical expertise and experience encompass a clinician’s knowledge, skills, and experience, as well as the context and resources available to them.
What types of evidence are utilized in the “Best Scientific Evidence” component of Evidence-Based Practice (EBP)?
A)
- Expert opinions and anecdotal experiences
- Randomised controlled trials and cohort studies
- Systematic reviews and clinical practice guidelines
B)
