How we made the decision
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.
For details of the process and update decisions that are available, see ensuring that published guidelines are current and accurate in developing NICE guidelines: the manual.
Evidence
This surveillance report provides an overview of 1 study published since the end of the search period for the guideline (October 2016). The results of this study were considered in detail to determine if there is an impact on guideline recommendations.
No additional evidence published since the last surveillance review in April 2017 was considered.
Views of topic experts
We considered the views of topic experts, including those who helped to develop the guideline.
Views of stakeholders
Stakeholders are consulted only if we decide not to update the guideline following checks at 4 and 8 years after publication. Because this was an exceptional surveillance review we did not consult on the decision.
