From NICE:
“The updated guide has been amalgamated to contain details of both the Single Technology Appraisal (STA) and Multiple Technology Appraisal (MTA) processes and will come into effect when the first invitations for evidence submission to the Technology Appraisal programme are sent out post publication on the NICE website. For appraisals already ongoing, the process steps in the new guide will be followed wherever possible, from that point onwards.
Details of the key changes to the processes can be found in the Board paper from the meeting on 16 July (item 09) http://www.nice.org.uk/media/default/Get-involved/Meetings-In-Public/Public-board-meetings/Agenda-Papers-July-2014-Public-Board-Meeting-1.pdf”
