Goals of the Workshop
Understand what is PubMed and how it works
Understand the limitations of simple keyword searches
Comprehend some of the powerful techniques using Medical Subject Headings options
4
What is PubMed
Created and maintained by the U.S. National Library of Medicine,
Over 17 million citations From almost 5,000 health and life science journals Goes back to 1950s Updated daily Mostly bibliographic information 1 million free full text article via PubMed Central
(PMC) - http://www.pubmedcentral.nih.gov/
5
How to access PubMed
www.pubmed.gov Google PubMed
6
Simple search - keywords
For a quick and dirty “Google-style” search, just type your
keywords into PubMed’s Search box
Let’s try to find some literature on effectiveness of continuous
passive motion (CPM) therapy for knee replacement rehab
7
Simple search - keywords
PubMed located 40 articles (from 17 million) that mention all words
we typed in the search box.
This is a good quick and dirty search for such a small topic…
However, we don’t want those articles that just mention our
keywords; we want article that focus on effectiveness of CPM for
knee replacement rehab! Aha…for that, we need to understand Medical Subject Headings http://www.nlm.nih.gov/mesh/
8
Introducing MeSH
Medical Subject Headings (MeSH): U.S. National Library of Medicine's
controlled vocabulary Access MeSH from the left-hand sidebar
Note: Controlled vocabularies bring all variations of a concept under one “approved” term or phrase which makes searching more
efficient (Example: Neoplasm is the controlled term in MeSH for variations and synonyms of
cancer, tumors, etc.)
9
Using MeSH
To locate an appropriate MeSH for your term, search PubMed
MeSH sub-database
Let’s try to see what PubMed uses for knee replacement Go to MeSH and type your terms in…
10
Using MeSH
The MeSH term is Arthroplasty, Replacement, Knee
Read the blurb to decide whether this MeSH term is relevant
Select one or more subheadings if appropriate – these will narrow your search down to more specific areas of research
11
Using MeSH
Steps involved: First, we select a proper MeSH (click the checkbox) We select “Search Box with And” from the “Sent to” drop down
menu
12
Using MeSH
Then, we click on PubMed search button to search all 17 million articles for our selected MeSH topic
There are 282 articles that are about knee replacement rehab in PubMed
13
Using MeSH
Let’s do the same with our second term – CPM therapy The term is > Motion Therapy, Continuous Passive
355 citations are retrieved
14
Search history
See your last searches under “History” tab Alive for eight (8) hours only
15
Combine results
For both CPM therapy and knee replacement rehab use AND search operator
Only 21 articles retrieved (down from 41 at the beginning) – more precise searches, thanks to MeSH!!
16
Limits
Limit to EBP results, age groups, language, focus on specific
profession, etc. from the Limits tab
17
Limits
My limits:
18
Limits
Limits appear in a yellow bar
Now we have only three (3) studies – Wow!
19
Display
To view Abstracts, etc., change format from Display drop-down menu
20
Sort
Sort your results: Publication Date Author’s name Journal
21
Related Articles
Click to view closely related articles Note that you loose everything you applied so far: MeSH, limits,
etc.
22
Clipboard
Store your selected articles in Clipboard for eight (8) hours
Email, print, and do more with your articles after sending them
to the Clipboard, via “Send To” drop down menu
23
Find a citation
If you know what citation you are looking for, the easiest way to locate it in PubMed would be using “Single Citation Matcher”
24
myNCBI
Using freely available PubMed myNCBI you can:
Receive alerts about new articles published in your area of
expertise
Receive table of contents of your favorite journals (if indexed in
PubMed)
Save selected abstracts of articles into your collections
And much more…
25
