Select the best fit from the list Select the subheading(s) that best focuses your search Add the term to the search box Repeat until you have all the MeSH terms you want Select Search PubMed

Understanding MeSH MeSH -1 As previously stated MeSH, Medical Subject Headings is a controlled vocabulary. It was developed by the National Library of Medicine and used to index MEDLINE items in PubMed (not used for citations supplied by

Publisher or those not yet indexed) MeSH- 2 Searching for Pharmacy in MeSH results in 23 possible terms/descriptors with the definition below each term MeSH-3

Searching for Osteopathic in MeSH results in 4 terms/descriptors with the definition below each term. Notice one of terms is Manipulation, Chiropractic which probably would not be wanted MeSH -4

Selecting the first term Pharmacy results in all the subheadings available for that term being displayed along with the search box MeSH -5 If you scroll down the screen youll see a list of other possible terms and where a term falls within Mesh's hierarchal structure (Tree)

Note the different trees for Pharmacy and Osteopathic Physicians Mesh - 6 Searching for a term higher in the tree will retrieve everything indexed to the terms below it in the tree

Mesh-7 Searching for a group of individuals that fit a category The Persons tree has an extensive list of pre-categories groups ranging from Abortion Applicants to Vulnerable Persons Start by looking at this tree if you want to see

if the group youre looking for has been defined. Mesh-8 Under Persons are the terms population group and ethic group which are helpful in finding results to match patient characteristics

MeSH- 9 Geographic Regions if youre looking for a study that pertains to a geographic location you also use Mesh heres the tree for the Geographic region that includes New York MeSH -10

MeSH allows for a very focused search, but remember citations indexed by the publisher or just submitted may not be indexed and therefore would not be found by search using just MeSH terms.
