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.
This surveillance report provides an overview of 1 study published since the end of the search period for the guideline (April 2015). The results of this study were 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.

The NICE project team would like to thank the topic experts who participated in the surveillance process.
