The updating classification system is a decision-making framework to help editorial staff:

• decide which Cochrane Reviews to update
• report on the updating status of a Cochrane Review
• sort their portfolio of reviews into those in development and those up-to-date. See also Reviews. 

Updating tab

The Updating tab appears on the Review Properties once a review has been published as a Full Review. Classification status can be viewed in the Review folder view, and details are available as reports or when exporting Review data from search results.

• Updating status - the overall status of the review. Only users with Max review permissions can apply an updating status. You can choose from: 
  • Up to date
  • Update pending
  • No update planned
• Rationale - a brief reason for the relevance and status. There are set reasons to choose from, dependent on the update status.
• Explanation - provides more detail about the reasoning for the relevance and status. This section is free text, but sample texts are provided for editors to adapt.
• Internal notes - allows you to record further data, only visible on the Updating tab.
• History - records the history of the updating classifications. Each classification is linked to a particular review version.
