What is Evidence Based Health Care?
Evidence from research
Clinical experience
Patient preferences
Available resources
EVIDENCE BASED
DECISION
![Page 3: Evidence Based Surgical Nursing – Reviewing the Evidence](https://reader035.vdocuments.mx/reader035/viewer/2022070415/56814f46550346895dbce925/html5/thumbnails/3.jpg)
How do you focus your question?
Need to identify 3 things:
Who it is you are interested in - Population
What it is you are interested in - Intervention
What you are hoping for -
Outcome
![Page 4: Evidence Based Surgical Nursing – Reviewing the Evidence](https://reader035.vdocuments.mx/reader035/viewer/2022070415/56814f46550346895dbce925/html5/thumbnails/4.jpg)
An example….
In patients with opioid induced nausea and vomiting which is the most effective anti-emetic, metoclopramide or haloperidol
![Page 5: Evidence Based Surgical Nursing – Reviewing the Evidence](https://reader035.vdocuments.mx/reader035/viewer/2022070415/56814f46550346895dbce925/html5/thumbnails/5.jpg)
Population
Intervention
(Counter-intervention)
Outcome
Patients with opioid induced
nausea and vomiting
Metoclopramide
(Consider route of administration )
Haloperidol
(Consider route of administration )
Reduction in nausea/vomiting
(Consider how this might be monitored)

TYPE OFQUESTION
EXAMPLE BEST DESIGN
Effectiveness ofTreatment/Prevention;adverse effects oftreatments
Does compressionbandaging increase thehealing of venous leg ulcerscompared with nocompression?
Randomisedcontrolled trials(RCTs)
Causation Are people who have had adeep vein thrombosis morelikely to get a leg ulcer thanpeople who have not?
Cohort Study
Feelings;understanding;perceptions
How do people with venousleg ulcers feel about theirhealth and their lifestyle?

SEARCH EVIDENCE BASED JOURNALs FOR A PRE-APPRAISEDSYSTEMATIC REVIEW
SEARCH THE COCHRANE LIBRARY FOR A SYSTEMATIC REVIEW
SEARCH EVIDENCE BASED JOURNALs FOR APPRAISED PRIMARYRESEARCH eg. RCTs
SEARCH MEDLINE, CINAHL, COCHRANE LIBRARY (CochraneControlled Trials Register) FOR PRIMARY RESEARCH
No?
If you find one, rememberto appraise its quality
If you find some research,you need to appraise itsquality – use a checklist!

Making sense of a review
Is it valid?
What do the results mean?
How (can?) I apply it to my patients?
![Page 19: Evidence Based Surgical Nursing – Reviewing the Evidence](https://reader035.vdocuments.mx/reader035/viewer/2022070415/56814f46550346895dbce925/html5/thumbnails/19.jpg)
Screening.
SCREENING QUESTIONS
Is there a clearly focused question?
Did the authors look for the appropriate sort of research?
![Page 20: Evidence Based Surgical Nursing – Reviewing the Evidence](https://reader035.vdocuments.mx/reader035/viewer/2022070415/56814f46550346895dbce925/html5/thumbnails/20.jpg)
Detailed questions
Do you think the important, relevant studies were included?
Did the review’s authors do enough to assess the quality of the included studies?
If the results of the review have been combined, was it reasonable to do so?
![Page 21: Evidence Based Surgical Nursing – Reviewing the Evidence](https://reader035.vdocuments.mx/reader035/viewer/2022070415/56814f46550346895dbce925/html5/thumbnails/21.jpg)
What are the results?
What is the overall result of the review?
How precise are the results?
![Page 22: Evidence Based Surgical Nursing – Reviewing the Evidence](https://reader035.vdocuments.mx/reader035/viewer/2022070415/56814f46550346895dbce925/html5/thumbnails/22.jpg)

Will the results help locally?
Can the results be applied to the local population?
Were all the important outcomes considered?
Are the benefits worth the harms and costs?
