Who makes decisions

Interventional Procedures Advisory Committee (IPAC)

Find out:

  • who's on the committee
  • details of past meetings
  • forthcoming meetings
  • how to attend a committee meeting.

External Assessment Centres

We may decide to refer a procedure to an External Assessment Centre for a systematic review. This might happen if:

  • the evidence base is too large to prepare in the format of a standard overview
  • the procedure could cause serious adverse events and the evidence needs a complex statistical analysis to enable the IPAC to make a decision
  • the procedure has more than 1 indication or involves more than 1 technique.
