Objectives
After completing this lecture, you should be able to:





Identify the sources of evidence for primary questions
Develop a good search strategy and conduct an
efficient PubMed search using MeSH database
Find the highest levels of evidence using PubMed
Clinical Queries and Evidence-Based filters
Find evidence using Cochrane, PEDro, CINAHL, TRIP
Find evidence-based practice guideline (National
Guideline Clearinghouse)
2
Evidence-Based Medicine

The process of systematically finding, appraising, and
using contemporaneous research findings as the basis
for clinical decision.
 Formulate a clinical question
 Literature search
 Evaluate the evidence
 Implement findings in clinical practice

Key Databases for Evidence-Based
Physical Therapy Practice





PubMed@UCSF
CoChrane Library
PEDro
TRIP (Turing Research into Practice)
CINAHL
Hooked on Evidence (APTA)
5
Developing Search Strategies






Formulate a well-built clinical question (PICO).
Break your question into multiple concepts.
Locate the appropriate MeSH (indexed term) for
each concept.
Run the search using AND, OR, NOT
Apply limit options (date, language, age,
publication type, gender), major headings and
subheadings
Modify your search strategies and rerun your
search.
6
Boolean Operators (upper case)

AND
Combine different concepts to narrow
your search.
aged AND women  aged women

OR
Broaden your search to include similar
concepts.
HIV OR AIDS  AIDS patients

NOT
Exclude a concept from your search.
AIDS NOT hearing aids  AIDS patients
7
Searching PubMed: MeSH Terms

Using the MeSH Database to locate MeSH
terms; using MeSH terms to increase the
precision of your search results
8
When to use Keyword search?

New studies not yet indexed
e.g. PubMed – in process
PubMed – as supplied by publisher
Do a keyword search and limit search results
for the past few months.
search sample: (ACL OR anterior crucial
ligament) reconstruction
9
PubMed: Clinical Queries


Finding the highest levels of evidence:
systematic reviews and meta-analyses faster
and easier
Providing further analysis of randomized
controlled trials

Graft choice in ACL reconstruction
10
Setting up Evidence-Based Filters
Using my NCBI


Filters help sort search results faster
Set up EB filters for systematic reviews,
meta-analyses, RCTs, practice guidelines
11
Set Up EB Filters Using My NCBI


Register My NCBI.
Setting up filters for systematic reviews, RCT, meta-analysis,
practice guideline and outcomes assessment




Select ‘Filters’ in the far left menu, and then select
PubMed.
Select ‘Browse’ to choose specific filters or select ‘Search’
to enter a specific filter.
For example: Select “Search” to look up ‘systematic
reviews’. Select Systematic reviews under the matching
filters list and then check the ‘Add’ box to automatically
add
systematic reviews as one of your filters.
Go back to ‘Search’ and repeat this with ‘meta-analysis”,
“randomized controlled trial”, “practice guideline” and
“outcomes
assessment.”

MyNCBI (Save Search, Updates)




Save search strategies and set up email updates
Set up user preferences – highlight search
words in your retrieval.
Setting up “User Preferences” for color highlighting:
Click “User Preferences” in the far left menu and
choose a color for highlighting.
13
Cochrane



Cochrane Database of Systematic Reviews
Database of Abstracts of Reviews of Effects
(DARE)
Cochrane Central Register of Controlled Trials
14
PEDro



Physiotherapy evidence-based database,
produced by the Centre for Evidence-Based
Phsiotherapy in Australia
Covers RCTs, systematic reviews, clinical
practice guidelines in physiotherapy
Trials rated for quality
15
TRIP


Searches over 75 sites of high quality
medical information
Provides you direct, hyperlinked access to
the evidence-based material on the web as
well as articles from premier online journals
such as BMJ, JAMA, NEJM and the Lancet
16
CINAHL



55% of overlap with MEDLINE
Indexes journal articles, books, book
chapters, dissertations, AV materials,
conference proceedings
Controlled vocabulary/thesaurus:
Nursing headings
Special Interest: Evidence-Based Practice
