2016 Ovid Embase® Reload – September 2016


2016 Ovid Embase® Reload

Dear Ovid Embase Customer:

New features and important changes are coming to Embase (EMED) on Ovid.

These changes will improve the overall Embase experience on Ovid and have been carefully considered in partnership with Elsevier, but as with any change we ask that you please carefully review the updates below and prepare accordingly. Ovid Customer Support is available if you have any questions at and we are eager to provide additional training and assistance during this transition as needed.

A short video explaining the highlights of the reload can be viewed here.

We expect the reload to go live on September 19th, 2016. Alerts were run on Saturday, September 17th 2016 prior to the reload.

This reload includes the following highlights (and you can find important details of items in the sections below):

There are a total of nine subheadings that are now designated key subheadings, (5 key subheadings for drugs, 2 key subheadings for diseases and 2 key subheadings for devices). (see below for examples)
  • Medical Device subheadings can now be searched and will display in the Subject Headings field.

  • Multipurpose field .mp. will now include .fs. (free floating subheadings) and can be searched when spelled in full.

New Record Status Limits

All Embase article statuses will now be included in the front segment of Embase. If you would like to limit to some or all records you will have the ability to use the statuses below for records received this year (2016). Status limits will not work for records received prior to January 1st 2016.

  • Articles in Press Status
  • Conference Abstract Status
  • Embase Status
  • Inprocess Status
  • MEDLINE® Status

If you do not want to receive certain statuses (such as Articles in Press) in your search and alert results, you will need to adjust your search strategies.

Key Changes to Date Fields

Due to numerous customer requests and in order to align with how dates are handled on, we have updated our date fields as follows:

  • The Date Created (DC) field will now contain the date on which the original Citation & Abstract file was created in Embase by Elsevier.
  • Note that the Date Created (DC) field will now contain the date that was previously labeled as Date Delivered (DD) because Date Created (DC) is a more accurate label for this date.
  • Customers who wish to use the date closest to when articles were delivered to Ovid should use the Date Delivered (DD) field within their Saved searches and Autoalerts.
  • For clarity, older records will reflect these date changes as well.

You may need to change your autoalerts and saved search strategies prior to the reload if you prefer the new Date Created (DC) or Date Delivered (DD) fields. Contact Ovid Customer Support for assistance in editing existing saved searches and autoalerts.

Triple Indexing (“triples”) Examples:

  • Drug therapy: when this subheading is indexed, the diseases treated are also indexed with the disease subheading drug therapy.
  • Drug therapy: when this subheading is indexed, the drugs used to treat the indexed disease are also indexed with drug subheading drug therapy.
  • Adverse device effect: when this subheading is indexed, the adverse effects are also indexed when possible with the disease subheading complication.
