Aims of surveillance
During surveillance, NICE identifies information that contradicts, reinforces or clarifies our guidance recommendations. This process informs decisions on whether guidance recommendations should be updated, amended, retired, or incorporated into another guidance product.
The surveillance process must therefore gather enough information to inform these decisions.
The NICE prioritisation board makes some of the decisions on whether to change guidance. It follows the methods and processes set out in the NICE-wide topic prioritisation manual.
