Coordination
Printer-friendly Version
Most concepts cannot be adequately described with a single MeSH term. Coordination is the use of a combination of the appropriate MeSH headings, subheadings, and check tags to index a concept as specifically as possible.
Coordination can be accomplished as follows:
Using a subheading to describe a specific aspect of a MeSH heading:
| Example: | “Radiographic imaging of a lung tumor” is indexed as:
|
Using two MeSH headings:
| Example: | “The medical staff in teaching hospitals” is indexed as:
|
Coordinating subheadings on two or more headings:
/drug therapy on a disease term usually requires /therapeutic use on one or more drug terms.
| Example: | "Treatment of HIV infections with HIV protease inhibitors" is indexed as: HIV Infections/drug therapy |
/metabolism on an endogenous compound may require /metabolism on an organ, an organism, and/or a disease term.
| Example: | "Inability to metabolize copper" (as in Wilson's Disease) is indexed as:
Copper/metabolism |
/pathology on a disease term often requires /pathology on an organ term.
| Example: | Myopia/pathology |
Coordinating a major (asterisked) MeSH heading with an non-major (non-asterisked) MeSH heading that further describes the concept:
| Example: | “Glycosylation of ceramides” is indexed as: |
|
|
(indicates that metabolism of ceramides is the main point of the article) | |
|
(specifies the metabolic process) | |
Coordinating a heading with one or more check tags:
| Example: | "Preventing pre-eclampsia" in women is indexed as:
|
Indexing a "pre-coordinated" MeSH heading which combines two concepts into one:
| Example: | "Staphylococcal pneumonia" is indexed as:
Rather than:
|
