How we made the decision

We check our guidelines regularly to ensure they remain up to date. We based the decision on surveillance 8 years after the publication of the NICE guideline on diagnosis and initial management of stroke and transient ischaemic attack.

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.

Previous surveillance update decisions for the guideline are on our website.

New evidence

We found 166 new studies in a search for randomised controlled trials and systematic reviews published between 29 January 2014 and 1 December 2015. We also considered 3 additional studies identified by members of the guideline committee who originally worked on this guideline.

Evidence from 180 studies identified in previous surveillance 3 years and 6 years after publication of the guideline was also considered.

From all sources, 349 studies were considered to be relevant to the guideline.

We also checked for relevant ongoing research, which will be evaluated again at the next surveillance review of the guideline.

See appendix A for summaries of evidence and references for all new studies considered.

Views of topic experts

We considered the views of topic experts, including those who helped to develop the guideline and other correspondence we have received since the publication of the guideline. This included a meeting with experts to discuss potential areas for update.

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 8‑year 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.
