About this information standard

SNOMED CT is the information standard for clinical terminology. It has been declared as the required terminology to support direct management of care within the policy document published by the National Information Board (NIB) 'Personalised Health and Care 2020: A Framework for Action'.

SNOMED CT was first published as an information standard by the Information Standards Board (ISB) in August 2011, the original documents remain on the ISB website.

This change seeks to ensure its implementation is planned to coincide with national requirements in relation to electronic records. There are three elements to the change:

  1. Confirmation of the timescales for the cessation of SNOMED CT releases in Release Format 1 (RF1) and the subsequent move to releases only being provided in Release Format 2 (RF2). All existing users (including any social care providers) will need to change to RF2.
  2. Conversion of the current information standard to align with the requirements of the Health and Social Care Act 2012. This includes the provision of Implementation Guidance.
  3. Confirmation of application of this standard in specified operational settings including implementation dates in alignment with national policy.

This information standard is published under section 250 of the Health and Social Care Act 2012. An Information Standards Notice (see below) provides an overview of scope and implementation timescales and the other listed documents provide further detail for those who have to implement the information standard.

Update 2 August 2017:

Note that since publication of Amd 35/2016 an addendum has been published to clarify the expectations placed on system suppliers in relation to the implementation of SNOMED CT. This addendum, available below, makes no changes to the published information standard.
