Project Information

Scope Statement

Scope: Provide a set of classified requirements for the representation of negated clinical data, which standards developers can use to confirm coverage of requirements, demonstrate recommended patterns, and identify out-of-specification patterns.

Need: The ways current interoperability standards handle negation, or propose to do so,

  • are inconsistent & may not support transformations among different standards
  • may not support representation requirements
  • may not support computation requirements

Having a consistently articulated set of clinical requirements will allow standards designers to confirm support for these requirements and to provide clear guidance on recommended and prohibited patterns.
