  • Since morning we have repeatedly focussed on tag words or keywords. They are important in selecting the topic, in writing the protocol, in writing the title and introduction too. And now I will discuss how important they are in review of literature.

    Tips on searching PUBMED
    Intro to Cochrane Library
    Google
  • Resources
    www
    Books and Journals
    Library
  • www
    Vast data bank but very difficult to get relevant information
    It does not act on questions like “best article on high flex TKR”
    It Requires “Keywords”
  • Keywords
    Pillars of the Reference search [Keystones]
    If you have your keywords right, reference search is piece of cake
  • Keywords
    Defined by topic of Search
    Conventionally they are talked in term of
    P – Population [TKR]
    I – Intervention [HIGH Flexion]
    C – Control [Conventional TKR]
    O – Outcome Measure [Functional]
  • www Resources
    Pubmed
    Google
    Cochrane
  • Level of Evidence
  • Level of Evidence
  • Pubmed - Tip 1
    If you directly put keywords in the pubmed you get
    - Hits containing the keyword
    Which means the hits
    - may not be about your terms
  • PubMed Tip 2
    Concept of Fields
    IN square Bracket [ ] After the key word
    - Author [au]
    - Title [ti]
    - Journal Name [jour]
    - Abstract [tiab] etc…
  • Author
  • Title
  • Title + Abstract
  • “Fields”
    An entire list of field tags is available online
    http://www.nlm.nih.gov/bsd/mms/medlineelements.html
  • Tip 3
    But we need to search multiple Keywords?
    BOOLEAN OPERATORS
    -Boolean operators define the relationships between words or groups of words
  • Main Boolean Operators
  • What do they mean
  • In Short
  • Search Using Boolean Operator OR
    Total knee arthroplasty OR Functional Outcome
    Total Knee Arthroplasty
    Functional outcome
  • Total knee arthroplasty and Functional Outcome
    High Flex TKR
    Functional outcome
    Search Using Boolean Operator And
  • Handling Combination
    We want articles by Gautam Shetty in Journal of Arthroplasty
    Shetty GM [AU] Journal Of Arthroplasty [JOUR]
  • FOR OUR EXAMPLE
    Total Knee Arthroplasty [Tiab]
    And
    (High Flexion [Tiab] Or Standard [Tiab])
  • Is [TIAB] Enough
    Multiple Words
    - total knee arthroplasty
    - total knee replacement
    -TKR
    -TKA
    - Knee endoprosthesis
    Need for identification of Subject matter irrespective of the keywords
  • MESH terms
    Especially made by PUBMED index
    Total knee replacement [ti]
    - gets all articles with Total knee replacement
    Total Knee Replacement [Mesh]
    - gets all article with Total knee replacement as a MESH term
    Meaning – the article is about total knee replacement
  • Search Using MESH term
  • Pubmed – Verifying References
    Single Citation Matcher
    Shetty GM knee alignment 2011
  • Pubmed 5 points
    Word Search
    Field Search
    Boolean Operators
    MESH Search
    Citation Matcher
  • Pubmed
    Most Useful Resource
    Follow steps
    Needs Practise to get acquainted
    It is not Google
  • Citation
    Articles searched through Pubmed using keywords
    Total Knee Arthroplasty [Tiab] (High
    Flexion [Tiab] Or Standard [Tiab]) with And as booleanOpearator
  • Pubmed
    Limiting searches to only case series, retrospective studies, RCT etc
    Limiting search to years
    Limiting searches to specific journal, specific MESH term
    Many more…..
