    • You are assisting a research team or are writing a thesis
  • Comprehensive Search Strategies
    • Search multiple databases
    • Use Ovid MEDLINE (instead of PubMed) for your search
    • Set up a RefWorks* (or similar product) account to manage your citations
    • Design a explicit, systematic search strategy that can be reproduced
    • Use both keywords and subject headings
  • Scenario
    • You are hired by a faculty researcher who is conducting research on hearing loss in AIDS patients. They ask you to find every article published on the subject.
  • Exercise
    • Spend about two minutes to conduct a quick search in PubMed on the topic:
    • AIDS and hearing loss
    • What is the quality of your results?
  • Exercise
    • Find the Medical Subject Headings (MeSH) for:
        • AIDS

        • Deaf
    • Which term should you explode?
  • Exercise

  • Search Scenario #2: The Clinical Question
    • You need to answer a question at the point of care to:
      • Support a clinical decision
      • Answer a patient’s question
  • Clinical Question Types
      • Aetiology: What is the cause of the disease and its mode of operation?
      • Diagnosis: How accurate is this diagnostic test?
      • Prognosis: What is the probable course of the disease?
      • Therapy: Is one intervention more effective than another?
      • Prevention: How to reduce the risk of this disease?
      • Cost-effectiveness: Is one intervention more cost-effective than another?
      • Quality of life: What will be the patient’s quality of life?
  • Clinical Question Strategy
    • Use Clinical Queries in PubMed to find the best studies to answer your question
    Enter your keywords and select the type of question that you want to answer
  • Scenario
    • A patient with rotator cuff tendinitis asks if you know of any new therapies that would be safe to try.
    • Exercise

  • Search Scenario #3: The Regular Update
    • You want to stay up to date on the latest publications, but don’t have time to run regular searches
  • Regular Update Strategy
    • Start an account with PubMed (MyNCBI)
      • Set up your search to run automatically and have the results sent to your email
  • Scenario
    • You’ve been seeing a lot of patients recently with rotator cuff tendinitis and would like to stay up to date on the most recent publications about treatments

  • Precise Search Strategy: Single Citation Matcher Enter as much information as you can and PubMed will find the closest matching article(s)
  • Scenario
    • Your preceptor asks you to read an article in the journal Lung about a respiratory syndrome affecting survivors of the World Trade Center disaster. They can’t recall anything more about the article.
    • Exercise
    • Use Single Citation Matcher to find the article
