Updating Classification System for Cochrane Reviews

The Updating Classification System (UCS) guides readers as to whether a Cochrane Review is up to date, likely to be updated in future, or does not need updating at the current time. The system can also help Cochrane Review Groups (CRGs) with prioritisation decisions for individual Cochrane Reviews. The UCS follows a decision framework that asks about the usage and currency of the review question, the availability of new studies or information, and how new information would impact on the review; and also whether new methods will make important changes to the review.

The Updating Classification System has three parameters:

  1. Updating Status: Provides readers with a guide to the status of the Cochrane Review, and the likely future plans for the Cochrane Review with respect to updating.
  2. Rationale: Provides a brief reason for the relevance and status.
  3. Explanation: Provides more detail to readers about the reasoning for the relevance and status. It also guides readers to more relevant Cochrane Reviews if available. This section is free text, but sample texts are provided for editors to adapt.

The UCS allows an editorial team to apply an Updating Status (along with the accompanying Rationale and Explanation) in Archie. These will be published alongside a Cochrane Review (i.e. are not part of the article). The Updating Status can be applied and updated as frequently as needed, as its publication is not dependent on publication of the Cochrane Review (although the two are closely linked in certain cases).

Updating Classification System: guide to applying to Cochrane Reviews

This guide includes information on the plan for rolling out the Updating Classification System (UCS), applying the UCS to a Cochrane Review, and publication in the Cochrane Database of Systematic Reviews (CDSR), on the Cochrane Library. It also has information on how to use the UCS in Archie, including UCS reports, and searching by using the UCS status in Archie. Download the guide: version 14 September 2016
