Are you planning to do an additional search in Embase based on a PubMed search strategy? This step-by-step plan can guide you with the translation:
Translating a PubMed search strategy to Embase differs between the MeSH terms and searches by word.
Complicated search strategy? First, break down your PubMed search strategy into the separate concepts (e.g. PICO or DDO). Then, convert the MeSH terms and searches by word separately for each concept.
A translated PubMed (or MEDLINE) search may yield much higher numbers in Embase. This has several causes:
By entering the search concepts separately in Embase and PubMed and comparing numbers, you can quickly see whether a difference in numbers is due to a specific search concept or search term.
Do you have a MEDLINE (Ovid) search strategy that you would like to translate to Embase?
Follow our Step-by-step plan: Translating a PubMed search to Embase. Translating a Medline search to Embase is easier, because Medline and Embase have the same interface (Ovid).The tabs in this box also provide extra tips for each step for MEDLINE users.
MeSH terms cannot be translated to Emtree terms in a one-to-one fashion, because PubMed and Embase each have their own thesaurus (system for keywords). You will need to manually look up relevant Emtree terms for each search concept.
The page Emtree explains how to look up Emtree terms.
Note the following differences between PubMed and Embase:
Tip for MEDLINE users
The MeSH terms in MEDLINE are identical to the MeSH terms in PubMed. The explanation given above also applies to the translation of MeSH terms in MEDLINE to Emtree terms in Embase. There is one exception: in both Embase and MEDLINE narrower terms are not automatically included.
When you have written out the searches by word for PubMed, you can easily convert them to Embase by replacing the field codes with the find and replace function (ctrl + H) in Microsoft Word. Irrespective of whether an article is found in PubMed or Embase, the words from the title and abstract remain the same.
View the page Search by Word for more search options in Embase.
|[tiab]||.ti,ab,kf.||title, abstract and author keywords*|
[tw] (= title, abstract, other abstract, MeSH terms, MeSH subheadings, publication types, substance names, personal name as subject, corporate author, secondary source, comment/correction notes, and other terms)
.mp. (= title, abstract, keyword, original title, heading word, floating subheading word, drug trade name, drug manufacturer, device trade name, device manufacturer, candidate term word)
|[all fields]||.af.||all search fields|
Tip for MEDLINE users
To search by word, Embase uses the same field codes as MEDLINE, so searches by word in MEDLINE can be copy-pasted to Embase.
An overview of Embase field codes is presented in the tab Search Fields in Embase (See box: Search fields).
You are writing a review on the deteriorating hand function in patients with Duchenne muscular dystrophy. In PubMed you have used the following search strategy:
( Duchenne Muscular Dystrophy[MeSH] OR Duchenne[tiab] OR DMD[tiab] )
( Forearm[Mesh] OR Hand[Mesh] OR Forearm[tiab] OR Forearms[tiab] OR Wrist[tiab] OR Wrists[tiab] OR Hand[tiab] OR Hands[tiab] OR Finger[tiab] OR Fingers[tiab] OR Thumb[tiab] OR Thumbs[tiab] OR Metacarp*[tiab] )
However, PubMed returns very few relevant articles, and you decide to additionally search Embase for extra publications. How would you translate the PubMed search strategy to Embase?
You are writing a review on the deteriorating hand function in patients with Duchenne muscular dystrophy. In MEDLINE you have used the following search strategy:
( Muscular Dystrophy, Duchenne/ OR (Duchenne OR DMD).ti,ab,kf. )
( Forearm/ OR exp Hand/ OR (Forearm OR Forearms OR Wrist OR Wrists OR Hand OR Hands OR Finger OR Fingers OR Thumb OR Thumbs OR Metacarp*).ti,ab,kf. )
However, MEDLINE returns very few relevant articles, and you decide to additionally search Embase for extra publications. How would you translate the MEDLINE search strategy to Embase?
A suitable Embase search strategy for this topic is:
( Duchenne muscular dystrophy/ OR (Duchenne OR DMD).ti,ab,kf. ) AND ( forearm/ OR exp hand/ OR wrist/ OR (Forearm OR Forearms OR Wrist OR Wrists OR Hand OR Hands OR Finger OR Fingers OR Thumb OR Thumbs OR Metacarp*).ti,ab,kf. )
In PubMed (and MEDLINE) Wrist[MeSH] is a narrower term of Hand[MeSH], and is therefore automatically included when searching with Hand[MeSH] (or exp Hand/ in MEDLINE). In Embase, the Emtree term wrist/ is not a narrower term of hand/, but of arm/. Therefore, wrist/ needs to be added separately.
