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 a cohort screening study published since the publication of NICE guideline CG164. The results of this study, alongside topic expert feedback, were considered in detail to determine if there was an impact on the recommendations within NICE guideline CG164.
Because this was an exceptional surveillance review, we did not consult on the decision.
