Introduction

Data Standards is a mandatory technical standard Standard which defines the data and information standards 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 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 ongoing 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.
