Analysis Method Notices


An Analysis Method Notice (AMN) is a communication of a new or changed analysis method to NHS and partner organisations and system suppliers. These formally document the methods for undertaking national analyses of NHS Wales healthcare data and the calculation of national indicators and performance measures. They are intended to improve the consistency of application of such methods to NHS Wales healthcare data across NHS Wales organisations and other national bodies.

Analysis Methods are developed and / or agreed by the Analysis Methodologies Group and accredited by the Welsh Information Standards Board (WISB). Further details about the Analysis Methodologies Group, including Terms of Reference and Membership, are available through the Analysis Methodologies Group page. AMNs are issued to the Service once a new or changed Analysis Method is reviewed by Analysis Methodologies Group and accredited by the Welsh Information Standards Board.
