Overview of 2019 surveillance methods
Exceptionally, significant new evidence may mean an update of a guideline is agreed before the next scheduled check of the need for an update. The evidence might be a single piece of evidence, an accumulation of evidence or other published NICE guidance.
This exceptional review provides an overview of 2 studies and a Coroner's report published since the end of the search period for the previous surveillance review (March 2017). The results of this new evidence was considered in detail to determine if there is an impact on guideline recommendations.
We considered the views of topic experts, including those who helped to develop the guideline.
Because this was an exceptional surveillance review we did not consult on the decision.
For further details about the process and the possible update decisions that are available, see ensuring that published guidelines are current and accurate in developing NICE guidelines: the manual.
