NICE decision aids are reviewed as part of the surveillance process for the guidance to which they relate. If the guidance and the relevant recommendations are modified, the decision aid is updated or withdrawn. The decision aid may also be updated or withdrawn before the guideline is updated if there are changes to the licensing arrangements for medicines to which the decision aid refers, relevant safety warnings are issued by the MHRA or there are changes to relevant legislation or usual NHS practice.
