Searching EMBASE
Alex DenbyRegional MI ManagerLondon Medicines Information Service(Northwick Park Hospital)
Session aims
To understand the concepts of a basic search strategy in Embase
To describe the EMTREE thesaurus in detail so that you will be able to apply EMTREE to use Embase efficiently
To carry out advanced Embase searches
Plan
What is Embase? (precourse material)
Medline v Embase (precourse material)
EMTREE NLH Software – searching tools Worked Examples
Searching EMBASE Controlled vocabulary = EMTREE Uses natural language US spellings rather than British INNs used where possible Acronyms & abbreviations can be
used Tree Structure – Hierarchy Indexing: Terms added/Drug names
Open Internet and type: http://www.evidence.nhs.uk/default.aspx
Select ‘Specialist resources’ / ‘Search Specialist Databases’
Enter Athens password Click on “Healthcare Database Advanced
Search” and select Embase
NLH Software
Explode Includes everything below in the tree
structure.‘exp’ is put before keyword in results
Major description (Focus)Only includes articles where the MeSH
heading (descriptor) is the main focus of the article
‘’ is put before keyword in results
Explode/Major descriptor
Many more subheading options for drugs compared with Medlinee.g. diclofenac
By choosing ‘Select’, all subheadings for the term will be chosen without either Exploding or Majoring on the term.
Subheadings
No real need to use them in EMBASE Most medicines have EMTREE terms
– even recently licensed ones If a drug hasn’t got an EMTREE term
assigned – use free text
CAS numbers
Publication types have their own facet / tree top of EMTREE terms that are searchable
Facet J: types of article or study Build up your search and combine in
the usual way (using BOOLEAN) with other search terms
Publication types
Worked example 1
Are there any papers specifically about the use of linezolid for the treatment of MRSA?
(Workshop question 1)
Worked example 2
Are there any review articles about inhaler use in asthmatic children under 4?
