Evidence Based Practice• What is EBP?– Most commonly cited definition is “the
conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients.”
– Sackett, D.L., Rosenberg, W.M.C., Gray, J.A.M., Haynes, R.B., & Richardson, W.S. (1996, January 13). Evidence-based medicine: what it is and what it isn’t. BMJ, 312(71).

Evidence Based PracticeThe EBP Cycle
• Identifying a clinical problem• Formulating a focused, answerable question• Locating relevant and appropriate resources • Searching for information • Critically appraising the information• Implementation in clinical practice
![Page 8: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/8.jpg)
Form a Clinical Question
• Must be focused and answerable
NOTWhat are therapies for depression?
INSTEADDoes exercise reduce depressive symptoms in women?
![Page 9: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/9.jpg)
Form a Clinical Question
PICO framework:
P – patient/problemI – interventionC – comparisonO – outcome
![Page 10: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/10.jpg)
Form a Clinical Question
Does exercise reduce depressive symptoms in women?
P – women with depression (age group?)I – exercise (how strenuous? how often?)C – medicationO – symptom reduction, quality of life
![Page 11: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/11.jpg)
Locate Resources
• Where is the Evidence?– Traditional bibliographic databases– Meta-search engines– Point of Care resources
![Page 12: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/12.jpg)
Bibliographic Databases
• MEDLINE– via EBSCOhost– via PubMed
• CINAHL• Cochrane Library• Joanna Briggs Institute EBP Resources
![Page 13: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/13.jpg)
Meta-search Engines
• SUMsearch – http://sumsearch.org• TRIP database – http://www.tripdatabase.org
![Page 14: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/14.jpg)
Point of Care Tools
• DynaMed• Essential Evidence Plus• Natural Standard• Lexicomp
![Page 15: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/15.jpg)
Search for Information
• Advanced Search Strategies– Boolean Operators– Field Searching– Subject Headings– Limiters– Research Filters
![Page 16: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/16.jpg)
Boolean OperatorsAND – both terms must be present (will narrow a search)
OR – either term is present (will broaden a search)
NOT – only first term is present (will exclude terms)
![Page 17: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/17.jpg)
Boolean Operators
• exercise AND depression – will retrieve articles with both words
• zoloft OR sertraline – will retrieve articles with either word
• exercise NOT running – will retrieve articles with exercise and exclude those with running
![Page 18: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/18.jpg)
Field Searching
![Page 19: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/19.jpg)
Subject Headings
• Specific words or phrases selected from a controlled vocabulary that describe a work – MEDLINE = MeSH– CINAHL = CINAHL Headings
![Page 20: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/20.jpg)
Limiters• Parameters for your search – MEDLINE limiters include:• Age group• Publication type• Language• Dates
![Page 21: Using the Library & Searching for the Evidence](https://reader035.fdocuments.us/reader035/viewer/2022070518/58d1c1bd1a28ab705c8b481f/html5/thumbnails/21.jpg)
Research Filters• Research filters are pre-designed search strategies• Clinical Queries
– PubMed page: http://www.ncbi.nlm.nih.gov/pubmed/clinical– Limiter in MEDLINE (EBSCOhost)
– ((clinical[Title/Abstract] AND trial[Title/Abstract]) OR clinical trials[MeSH Terms] OR clinical trial[Publication Type] OR random*[Title/Abstract] OR random allocation[MeSH Terms] OR therapeutic use[MeSH Subheading])
