Description

Excerpt

Defines detailed technical standards for the storage, management and organisation of data and specifies standardised reference data, terminology and codes.


Data Standards is a mandatory technical standard which defines the data and information standards that must be adhered to and the operational and information reference data such as clinical terminology, drug database data sets, and organisational codes which must be utilised within the Solution to provide consistency of information.

NHS data standards are contained in the NHS Data Dictionary and Manual in the form of an entity relationship diagram or data model. The NHS Data Dictionary and Manual also holds the standards for field lengths and formats, and codes for classification lists.

Solutions are to use Organisation Data Service (ODS) data as the primary source of reference data for NHS related organisations and individuals. Solution will provide the UK Edition of SNOMED CT as its primary coding scheme; this will have, where appropriate, primacy over any other deprecated coding terminology For further information, see SNOMED CT.

Solutions are expected to enable efficient coding, and retrieval of clinical information for use both within the Catalogue Solution and other Solutions externally by appropriate third parties to support on-going and future Patient care. Clinical Terminology, such as SNOMED CT, is essential for the interoperability of electronic health records across care settings. The standard supports the conversion of machine-readable code into meaningful, human-readable defined text and vice versa, thus providing a basis for supporting communication between clinicians, and the safe transfer of data between Solutions.

When supporting data entry and viewing data:

  • Where a User is searching for a term, all synonyms to be displayed
  • Where a User has ‘found’ or selected a term, the Preferred Term to be offered/highlighted to the User
  • Where a User wishes to enter a term other than the Preferred Term, this will be permitted
  • The selected clinical term will always be displayed irrespective of method to select a term e.g. if a User searched for Term A and found and selected a Preferred Term i.e. Term B, Term B to be stored in the Patient Record
  • All SNOMED CT concepts (excluding Metadata concepts) can be available to view (if not select), even when a managed subset of SNOMED CT is being used by the Solution to maintain visibility of relationships and hierarchical context.

Local collections of clinical terms

Define and manage local collections/lists of clinical terms (known in SNOMED CT as subsets). Functionality to include:

  • Unique identifier and/or name and version for each collection/list
  • Addition of multiple clinical terms – User to be notified / alerted if they attempt to add a clinical term to collection where another clinical term that represents the same Concept already exists within the collection/lists, though the Solution won't restrict subsequent inclusion of the term within the collection/list

Temporary/local terms

Define, use and manage temporary/local terms i.e. non-national codes that are expected to be superseded, whether these are local to an organisation or not e.g. for specific local purposes or as a ‘placeholder’ while a new clinical term is being requested/added to the coding scheme by the relevant authorities. Functionality to include:

  • Clear differentiation between temporary/local terms and clinical terms from SNOMED CT
  • Replacement of such temporary/local terms across the Solution e.g. upon release of appropriate national code
  • Indicate to Users each time they opt to use a temporary/local term that the term will not be recognised outside of the organisation/Solution
  • Removal of temporary/local term to prevent further usage i.e. make such a term inactive

Solutions that provide for codes local to the organisation, will utilise the SNOMED CT namespace feature; registering a namespace to their organisation. All messages will use the organisation namespace identifier for local codes and not the national SNOMED identifier so as to distinguish between national and local codes.

All management of temporary/local terms will be conducted in a safe way that enables any records to be retrieved that might have been stored using a temporary/local term

A SNOMED CT concept can be made inactive, while its descriptions remain active. Where this occurs, suppliers to prevent the descriptions and thus the concept being available for data entry.

For existing templates and other data entry artefacts:

  • Supplier developed templates and data entry artefacts to be updated to remove inactive content within contractual timeframes or within six months of the content becoming inactive whichever is sooner.
  • User developed templates and data entry artefacts should be updated to remove inactive content within contractual timeframes or within six months whichever is sooner. The system must make it clear to users which artefacts require attention.
