Ovid MEDLINE Correction Records – July 2019


Ovid MEDLINE Correction Records

Dear Ovid MEDLINE customer:

Further to our communications on 15 May and 28 June, concerning the increased volumes of correction records, we want to inform you about the following change to Ovid MEDLINE.
We are introducing a new “multi-segment” for Ovid MEDLINE corrections called MEDCM. This change will be reflected in the database guide for Ovid MEDLINE under the Segments and Years of Coverage paragraph.

MEDCM – Ovid MEDLINE® Revisions:

  • MEDC1– December 2018 to April 2019
  • MEDC2 – May 2019
  • MEDC – June 2019 to present

AutoAlerts are not affected by this change. If MEDLINE correction records are included in your AutoAlerts, they will continue to run on the MEDC segment for any new records that match your alert strategy.

The next update for MEDLINE corrections/revisions is scheduled for 24 July and is expected to add 943,198 new correction records. AutoAlerts that include corrections may therefore see an increase in the number of results when the AutoAlert first runs after 24 July.

If you have any concerns or questions, please contact Ovid Support at [email protected] for assistance.
