Structured Clinical Vocabularies
   
Structured Clinical Vocabularies (SCVs), also known as "Controlled Clinical
Terminologies," are coding systems that allow patient information to be stored
in a way that allows computers to recognize and manipulate that information.
The ideal SCV would be intuitive, never ambiguous, comprehensive, detailed,
flexible, and always current with regard to progress in medical knowledge. Not
surprisingly, it hasn't been invented yet. But the SCV's that are in use play
very important roles, like making possible Automated Clinical Decision
Support (see the
EHR section for more on that)
