Support Alert

NHS Digital Information Standard Notice published (England)

The Information Standard Notice (ISN) outlines new common standards for medicine data transfer. 

This is important as it will support the transfer of medicines information between settings, enabling safer and more efficient medicine reconciliation. From 1 October 2021, you will need to assess all systems that provide electronic transfer of patient medication and allergy/intolerance data to ensure compliance. IT systems used to send and receive medication and allergy/intolerance information must do so using either NHS Digital APIs or APIs created using the specifications.   

Where you identify non-compliant message transfers, contact your supplier about developing new products or updating existing products to enable compliance or consider changing to suppliers offering compliant systems.


Full detail can be found in the Standard’s Requirements Specification 

These requirements must be met by 31 March 2023. Any questions about the ISN and the introduction of the standards can be directed to [email protected]
