This date applies to very few reviews and should be employed with caution and in consultation with the Cochrane Review Group (CRG). A review that is no longer being updated is one that is highly likely to maintain its current relevance for the foreseeable future (measured in years rather than months). Such reviews are the exception rather than the rule, and the decision to stop updating a review should be negotiated with the CRG, and reviewed periodically. Situations in which a review may be declared to be no longer updated include:
the intervention is superseded (bearing in mind that Cochrane reviews should be internationally relevant);
the conclusion is so certain that the addition of new information will not change it, and there are no foreseeable adverse effects of the intervention.
The review remains ‘no longer updated’ as long as the most recent ‘What’s new’ entry is a declaration of a ‘no longer updated’ review. If a subsequent ‘What’s new’ entry is added, the review is considered to be in line for updating as for other Cochrane reviews.
