    8. 8. Break down the research question Select your database Break down the research question into concepts Identify subject headings for each concept Identify text words for each concept  Use a “target article” to help identify search terms (keywords)  Use a worksheet to keep track of your terms  Your database will determine your subject headings and operators (i.e., truncation symbols) 8
    9. 9. Different databases have different subject headings Database Subject HeadingsMedline/PUBMED MeSHEMBASE EMTREECINAHL CINAHL HeadingsCochrane Library MeSHPsycINFO Thesaurus of Psychological Index TermsScopus, Web of Science N/A Select subject headings that are the closest match for your concept General descriptors: Anatomy More specific descriptors: Ankle 9
    10. 10. Search Strategy WorksheetSearch Strategy Worksheet_________________________________________________Search statement: I am looking for articles about ___________________________________________________________________After writing out the search statement, underline the key concepts. Decide how the concepts will be combined together using theAND and OR Boolean operators. Concepts to be ANDed go across the grid and concepts to be ORed go down the grid.Fill in the grid with the key concepts and possible synonyms for each concept. AND AND AND ANDORORORORORORORDatabases to search:___________________________________________________________________________________________Limits to apply:_______________________________________________________________________________________________ 10
    11. 11. Key Operators in OVIDOperator Command Example * Find alternate endings to this nurs* [will find nurse, nursing, word nurses] .tw. Search for this term in the anxiety.tw.

Conducing the Search Start with your first concept  Search for the subject headings first  Then search text words  Combine these synonymous searches with OR using your search history Repeat for your second, third, and subsequent concepts Finally, combine large search results set with AND Example MeSH search: hypertenstion AND toxicity 13

    30. 30. Search for MeSH Terms With the first search term (MRSA) entered in the PubMed search builder, we can continue to use the MeSH Database to find terms and build our PubMed search 30
    31. 31. Combining Concepts We want to find articles that include both the concept of MRSA AND the concept of Hand washing. So we added our second term to the search builder with the default AND Both terms have been added and we can now click the Search PubMed button. 31
