Preparation phase

  • wk0

    Procedure notified to us

    We look at the information available about the procedure and assess whether we need to gather more.  When we have enough information we prepare the brief. 

  • wk8

    Brief agreed

    The Interventional Procedures Advisory Committee (IPAC) agrees the brief.

    This can sometimes take longer than 8 weeks, for example if we have to get further information.

    IPAC is an independent advisory committee which meets monthly. The relevant meeting papers are sent to members 2 weeks prior to the meeting.

    Meetings are open to members of the public.

    Final guidance written

    The committee considers the comments received on the consultation document, then makes its final recommendations.

    Late comments from patient commentators may also be considered.

  • wk30


    Once our Guidance Executive has approved the final guidance, it is open to resolution. This is a final quality assurance step before the guidance is published.

    Anyone who commented on the consultation can request we make corrections if they believe:

    • there has been a breach of process
    • there are factual errors in the guidance.

    Commentators have 3 weeks to submit their comments.

    You can find out more about resolution in chapter 15 of the programme manual.

    Guidance issued

    If there are no resolution requests, the final guidance is published.

    If we receive resolution requests, we suspend publishing the guidance while we investigate them.
