The Commissioning Data Sets have notation to identify the business and/or processing rules which apply to individual Data Elements. This notation appears in the Rules column of the Commissioning Data Sets details page.
All Data Elements are subject to length validation. Some Data Elements are also subject to format and content validation against a list of permitted values defined in the NHS Data Model and Dictionary. The value lists are held on the Attribute which the Data Element is based on, plus default codes which are held on the Data Element itself.
|F||The format is validated, for example the format of a DATE must comply with the XML standard.|
|V||The Data Element is validated against an explicit list of permitted values as defined in the NHS Data Model and Dictionary.|
Some Data Elements are subject to additional Business Rules as indicated below:
- Prefix H = Healthcare Resource Group Business Rules.
- Prefix I = CDS-XML Schema anomalies and issues.
- Prefix N = NHS Data Standards and Policy Rules
- Prefix S = Secondary Uses Service Business Rules
|PREFIX||BUSINESS RULES: H - Healthcare Resource Group Business Rules|
|H4||This Data Element is used by the Secondary Uses Service to derive the Healthcare Resource Group 4.|
Failure to correctly populate this data element is likely to result in an incorrect Healthcare Resource Group, usually associated with lower levels of healthcare resource.
