This document provides information and guidance on conducting research for polysomnography. It discusses the differences between library databases and websites on the internet, and emphasizes that library databases contain peer-reviewed articles while websites can contain unreliable information. It also outlines the CRAP test for evaluating websites. Search techniques for library databases like PubMed and DynaMed are described. Finally, it provides tips for reviewing research articles and assistance available from the library.
2. Where do you
find research?

3. The Web vs. Library Databases
What’s the difference?
Library pays for
access to information
Articles have already
been printed in a
magazine or journal
or newspaper
In order to be
published, articles
went through a
review process.
Pass review process
= published =
Reliable
Articles you find
online are
sometimes free /
available through a
subscription that
the library paid for
Anyone can publish
a website
No review process
Need use your
critical thinking
skills!
Library Databases The Web
4. Website Evaluation Criteria
Use the CRAP test –
South Mountain Community College website
evaluation
C = Currency
R = Reliability
A = Authority
P = Purpose / Point of View
5. Criteria for Website Evaluation:
CRAP Test
• Last updated?
• Easy to find –
usually at the
bottom of the page
or on the first page
• Copyright date –
2015 – health
information – need
recent
• Is the content fact
or opinion?
• Does it match
other information
you have found?
• Is there bias?
C = Currency R = Reliability
6. Criteria for Website Evaluation:
CRAP Test
• Is there an about or
home page which
would identify the
author?
• If the author is
identified, is the
author reliable? Is
this person expert in
the field, not just an
enthusiast or a really
big fan?
• Is there contact
information?
• Are you being sold
something? Are there a
lot of ads that are not
labeled?
• What age range is the
website developed for?
Does it have a lot of
graphics or large print?
Is it professional
looking?
• Is it easy to navigate?
• What is the domain?
(.com, .org, .edu …)
A = Authority P = Purpose / Point of View

Select to search the MeSH; add terms as
necessary
Can add more than one search term in MeSH
Subheadings are easy to use here
Can search using field searching; different
results and the MeSH may not be used
Full-text where available
PMID #
14. PUBMED
Located at www.pubmed.gov
Use the basic search screen
Search details shows MESH and what
you are searching

uver
Vancouver Tab
16. Vocabulary
Use the MeSH (Medical Subject Headings)
The word you might use for something may not
be the same word that is used in the database
PMID
PubMed ID
18. Reviewing Articles
Relevancy: Does it answer your question?
What does the abstract say?
You may not understand the whole article, but you
will be able to get some information out of the full-
text
Scientific Article
Evidence: What type of evidence is it? RCT,
Case study, physician knowledge (editorial)
Full-text
19. FULL-TEXT …
HTML full-text
This is just the text, no graphs, pictures, etc.
It’s a little harder to read
PDF full-text
This is the best copy
Looks exactly like the journal page
Check here for full-text
May or may not own it
May link to a journal that we own OR
May have to interlibrary the article
PMID Number
Works the same way in PubMed
Type in number and you’ll see if it’s available full-text and you can get a
Vancouver citation
20. Interlibrary Loan …
A library service
Register
Receive books and journal articles that we do
not own
Articles will come to your HVCC email account
Books will arrive at the HVCC library and are
picked up at the circulation desk
Interlibrary Loan does take some time … plan
ahead if you would like to use it
21. Searching for BOOKS …
Library Catalog -
http://www.hvcc.edu/lrc/index.html
Select the tab that says books
Searches books in the HVCC library
World Cat Online Catalog -
http://hvcc.worldcat.org/advancedsearch/
Searches college and university libraries
throughout the US and internationally
Do you feel it is successful? Why? How do you know what you are getting it good information?
Medical professional – required to have more professional research then just patient information
Many times a professor will allow you to use a credible website for your research paper, in conjunction with journal articles from the library databases.
What is the difference?
Let’s go to the website to get a better explanation of this criteria
Device – use the proper name
Procedure –
This could be like your Google search – but using a reliable database that does not need to be evaluated because it’s already been evaluated
DynaMed is reference – similar to a textbook but has journal articles that back up the information that it finds
Evaluate Dynamed -
Journal entries – some are in the full-text
Evidence-based – points out where the information came from
UptoDate – clinical – AMC has – it is a database
Just the facts:
Google:
What is it? A search engine.
What does it contain? Websites.
How do you know if it’s reliable? – evaluation - need to identify whether the website is reliable for EVERY ONE!
How does it search? Maps to what you are looking for
Full-text? Yes, no, maybe
Handout: Website evaluation + sheet
PubMed:
What is it? A database
What does it contain? Journal articles, abstracts, book reviews, etc.
How do you know it’s reliable? Journal articles are peer-reviewed, they have been published
How does it search? MESH – Medical Subject headings, foundation, Google like, automatically tries to identify what you need
Full-Text? Free full-text, PMID # to get full-text from MEDLINE database, can save articles
MEDLINE with Full-Text:
What is it: A database
What does it contain? Journal articles, abstracts book reviews, guidelines – it is the same information as PubMed but the interface is different
How do you know it’s reliable? Journal articles are peer-reviewed, they have been published
How does it search? MESH – Medical Subject headings, foundation, not Google like, need to select the MESH, can search using pull down menus some automatic mapping of search words
Full-Text? Full-text is linked to journal list and through other databases, #PMID to see if it’s free in PubMed
PubMed and Medline search the same information! Look different / search differently but it’s the same journal articles
