First Steps

• Book mark Norris Medical Library Home Page http://www.usc.edu/nml.

• Use PubMed@USC from Norris Library, do not use PubMed.gov

• Set up a MyNCBI account…there you can save article collections and searches.

• “PubMed is a service of the U.S. National Library of Medicine that includes over 17 million citations from MEDLINE and other life science journals for biomedical articles back to the 1950s.” – from the PubMed home page.

PubMed Background“PubMed is a service of the U.S. National Library of Medicine that includes over 17 million citations from MEDLINE and other life science journals for biomedical articles back to the 1950s.” – from the PubMed home page.

PubMed and MEDLINE

• MEDLINE is a subset of PubMed.

• The 1-2 million article citation difference includes articles that are being processed and will move into MEDLINE... AND articles which will never be included in MEDLINE (e.g., not biomedical or not a reliable source).

• (18.3/16.7 as of 08/31/08)

Anatomy of PubMed• Walk through of PubMed search flow sheet

o See next slide• PubMed

o Not intuitiveo With repetition becomes familiar

• Keys: o Use MeSH (Medical Subject Headings) where

possibleo Search each term as you find it - It is saved in

“History” o Items in "History" may be combined

Hands-on portions1. Cerebral palsy - background information, foreground information    a. Full text of article 2. Single Citation Manager - a way to an article when you have limited information    a. Save Search, save Collection 3. Tiger's knee    a. Try it on your own, ask questions! 4. Stretching    a. Try it on your own, ask questions! 5. Stroke and Constraint Induced Movement Therapy    a. Try it on your own, ask questions!  

What if you were taking care of…

• A patient with cerebral palsy.• Begin by finding background information

(what sources do you use?) o Choose (print or electronic) books to find background

information• Next locate the latest information.

o For “cutting edge” use the “primary literature” (MEDLINE)

How to do it• “Cerebral palsy” is a MeSH term.• Narrow by using Subheading(s)• Limits help narrow a search to a

reasonable number of articles.• Find the latest articles ... limit by date.• 75 articles if limit to last two years, review

articles, humans and English • Show first article...

Tiger’s Knee

• Try this one on your own....• Say you were taking care of Tiger Woods,

after his recent anterior cruciate ligament repair. How would you find articles about rehabilitation after ACL repair?

• Ask us for help if you have questions!

Two Methods• In PubMed you can type in something like “anterior

cruciate ligament rehabilitation” (1515) or “anterior cruciate ligament AND rehabilitation” (1515)

• -- or --• We would argue for using MeSH terms

o More precise o MeSH 1: Anterior cruciate ligament/surgeryo MeSH 2: Physical therapy modalities/methodso Combine with AND (209)o Limit last • English and humans (173)o Add limits RCT, Meta Analysis, Practice guideline (38)o 1st article Physical Therapy (2007), show full text

Stretching

For a 63 year old male with low back pain, what duration of stretching exercises is required to improve hamstring muscle flexibility?Try to find an article to answer the question. Hints: Use the flow sheet as a guide, the sought for article is more than 5 years old.

Stroke Rehabilitation

Your new patient is a 65yo RH WF.  She had an ischemic stroke a little over a year ago. She still has minimal use of her right upper extremity. Her right lower extremity has improved to the point that she can ambulate without assistive devices.  You have heard of "constraint induced movement therapy". You want to know more about it before making a treatment plan for your patient.

Constraint induced movement therapyfor strokeWays to do it: 1. "Constraint induced movement therapy stroke" (154)    Limit: humans, English, RCT, Meta Analysis, Guideline (31)2. Concept 1: Constraint induced movement therapy    (Hint: MeSH is "Restraint, physical")    Concept 2: "Stroke", with rehabilitation Subheading    Combine 1 and 2 with AND (44)    Limits: humans, English (42)    Add more limits: RCT, Meta Analysis, Guideline (14)

Summary

• We have tried to cover basic resources at Norris Medical Library.

• We spent the most time on PubMed, and gave you time to do hands-on searches.
