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 updating. 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'.
We were notified of several programmes of work by NHS England, Public Health England and the Department of Health that could impact on current guideline recommendations.
We considered the views of topic experts, including those who helped to develop the guideline. This included discussion with invited topic experts at a workshop.
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, and the decision was to update, we did not consult on the decision.
See ensuring that published guidelines are current and accurate in 'Developing NICE guidelines: the manual' for more details on our consultation processes.
