What are the Steps of Evidence-based Practice ✔Correct Answer-• PICOT Question
• Collect the best evidence
• Critically appraise the evidence
• Integrate evidence, clinical expertise and patient factors/preferences to implement a decision
• Evaluate the outcome
• Disseminate the findings
What constitutes the "Evidence" in Evidence-Based Practice? ✔Correct Answer-- Best
research evidence
- patient values
- clinical expertise
• Grounded in the belief that humans are a composite of many body systems that can be
objectively measured, one at a time or in combination.
• The researcher strives to isolate the characteristics of interest and create a context free
picture of what is being studied.
- Context free means eliminating or controlling variables that may interfere with variables being
studied. ✔Correct Answer-Quantitive Research
•Embraces the wholeness of humans focusing on human experiences in a natural setting.
• Humans attribute meaning to their experiences and experiences evolve from life context.
- Life context - human/environment relationship. Pain is different for different people. It is
based upon a subjective perception. ✔Correct Answer-Qualitative Research
Collect the Best Evidence:PICOT Question Guides the Literature Search
Type of PICOT Questions:
- identify treatments to offer patients that do more good than harm and that are worth the
efforts and costs of using them
• Randomized controlled trial (RCT), cohort, case control, case series, meta-analysis/systematic
reviews of RCT ✔Correct Answer-Therapy/Treatment
Collect the Best Evidence: PICOT Question Guides the Literature Search
Type of PICOT Questions:
- identify causes for disease
• RCT, cohort studies, case control, case series ✔Correct Answer-etiology
, Collect the Best Evidence:PICOT Question Guides the Literature Search
Type of PICOT Questions:
- select and interpret diagnostic tests, in order to confirm or exclude a diagnosis, based on
considering their precision, accuracy, acceptability, expense, safety, etc.
• Cohort studies with comparison to gold standard test ✔Correct Answer-Diagnostic Test
Collect the Best Evidence:PICOT Question Guides the Literature Search

Type of PICOT Questions:
- determine what meaning patients (families, communities) give to conditions, diseases, and
circumstances
• Descriptive, qualitative studies, systematic reviews of qualitative/descriptive studies
✔Correct Answer-meaning
Finding the Best Evidence
What are levels of evidence ✔Correct Answer-- There are many different rating systems for
evidence. That range from 3-4 levels to 7-8 levels
with many subcategories in between
- We will use Melynk (2011) Hierarchy
of Evidence.
Melynk Evidence Rating System ✔Correct Answer-Pyramid goes from from bottom to top
higher up is where there is quality of evidence
Unfiltered information at the bottom of the pyramid:
- background information/expert opinion (bottom)
- case-controlled studies case series/reports
- cohort studies
- randomized controlled trials (RCTs)
Filtered Information top pyramid
- critically-appraised individual articles [article synopses]
- critically topics [evidence syntheses]
