Purpose of Class

Understand what PubMed is

Know when to use it

Know how to conduct a basic search

Understand how to use MeSH terms

Know how to find full text of an article

What Is PubMed???

PubMed Is…….

A freely available database

Created by the National Library of Medicine

Citations to scholarly literature

Covers fields of biomedicine and health

Big! Contains over 21 million citations, many with abstracts

PubMed Is….

Includes all of the content from MEDLINE

Also includes citations to articles not yet in MEDLINE (very old, or very new articles not yet indexed)

Includes selected articles in fields not covered by MEDLINE such as astrophysics

Coverage from 1946-Present

Why Should I Use PubMed???

High quality information; much of content peer-reviewed

Up-to-date; content added almost daily

Hot-off-the-press citations to articles not yet published or indexed in MEDLINE

Learn how to use now--most nurses in clinical settings do not have access to subscription databases like CINAHL (Dee & Stanley, 2005)

How Do I Get There???

Accessing PubMed…..

Always(!) access through Carroll College library webpage

Access through Carroll College provides customized version

Customized version contains links to additional full-text access for Carroll College users

On campus or off campus access

On Campus Access

Off Campus Access

How Do I Find Stuff????

Basic Search

Rheumatoid Arthritis Sinus Infections

Rheumatoid Arthritis Sinus Infection

Basic Search

HOW DO I KNOW WHAT TERMS TO USE?????

Basic Search

Medical Subject Headings

Subject terms assigned to articles by PubMed indexers, specialists who read article

Highly specific—over 26,000 terms

Excellent way to search PubMed

But…MeSH only works for citations that have been indexed, so you will miss some citations searching with MeSH

WHAT IF I GET 114,629 RESULTS?

Beyond Basic Search

Advanced Search

Filters

A Few Extra Search Tricks

Boolean Searching

Based on mathematical logic

Uses the words AND, OR, and NOT to connect search terms

These words (Boolean operators) can either limit or expand your search

Boolean Searching Using AND

Boolean Searching Using OR

Boolean Searching Using NOT

Truncation

Shortcut for finding all forms of a word

PubMed uses the asterisk character (*) for truncation

Nurs* would find nurse, nurses, nursing…..

Expands search

Be careful! Truncation turns off automatic term mapping in simple search—check search details!

Proximity Searching

Searches for words adjacent to each other

PubMed only allows for exact phrase searching—words next to each other in exact order

Use quotation marks to enclose search phrase—”Endonasal activity in WG is associated with”

Additional Search Strategies

Citation Matcher

I DID A GREAT SEARCH—NOW WHAT???

Managing Results

Finding Full Text of an Article

InterLibrary Loan

If we don’t have full text, we can get it from another library

InterLibrary Loan (ILL) form is available on library homepage

Fill in information using PubMed record

Delivery time for articles is often less than a week (but not always—plan wisely!)

Managing Citations

Clipboard holds information for 8 hours

Clipboard best for short sessions

My NCBI provides permanent storage of citations

My NCBI has many other helpful personalization features

My NCBI very useful if use PubMed regularly or for big projects

HELP!!

A Quick Review

Always access PubMed through the Carroll College library homepage

On Campus of Off Campus Access

Ensures optimal full text access

A Quick Recap

PubMed is the premier citation database for biomedical and health fields

PubMed comprised of citations, many with abstracts

Much of content is peer-reviewed

Some citations have link to full text

A Quick Recap

Basic search can be tricky—check Search Details

Searching with MeSH terms ensures relevant results

Additional helpful search tools such as filters and advanced searching

A Quick Recap

Use the Carroll College filter for full text access

Look for the “Full Text” icon with a purple “C”

Many options for managing results with clipboard (short term) or My NCBI (long term)

Finally…..

PubMed is a powerful tool with many more features

Takes some practice

C U M U L AT I V E I N D E X TO N U R S I N G A N D A L L I E D H E A LT H L I T E R AT U R E

CINAHL

Contains citations and full text with emphasis on nursing and allied health literature

Some overlap with PubMed, but each database has unique content

Can use many of the same search strategies we just covered in PubMed, but the search interface is different

CINAHL

Peer Reviewed Journals

Peer-Reviewed Journals

Can set limiters in CINAHL for only peer-reviewed journal articles

Will have to do your own research for citations from PubMed

Peer Reviewed Journals

Finally…..

PubMed and CINAHL are powerful tools with many more features

Takes some practicePlease ask librarians for help—that’s why we are
