2012 Ovid Medline Update

Each year Ovid updates the Medline database either changing or deleting MESH Headings and replacing them with the most up-to-date terminology.  New MESH (Medical Subject Headings) terms are also added.

If you have searches saved or alerts set up using this database these changes may affect your search strategy.  It therefore may be useful to review your searches on an annual basis to check that they still run properly.  Are your subject headings still recognised and/or are there new terms that could be added?

This year’s update has now been completed with 454 new MeSH Headings were added to MeSH in 2012. A further  57 existing MeSH Headings were either changed or deleted and replaced with more up-to-date terminology.  Click on the links to see if any apply to you.

If you would like further information, the NLM Technical Bulletin traditionally includes information about changes made to MEDLINE during annual National Library of Medicine maintenance known as Year-End Processing (YEP). This bulletin collects, in one place, the notable data changes for 2012.

If you have any queries or would like any help in updating an existing search contact the NHS Liaison support team on 0208 725 5433 for advice or to arrange an appointment.
