Review decision: 

  • Following the recent surveillance review which checks the need to update CG109, this guideline should not be updated at this time and the guidance should be transferred to the static list. Guidelines on the static list will remain extant and will be checked for the need for an update at 5-year intervals, or if new evidence emerges.

Next review date: October 2019
