Unit 6Vendor strategies for terminology, knowledge management, and data

exchange

Objective

• Evaluate EHR strategies for terminology management, knowledge management and data exchange

Component 14/Unit 6Health IT Workforce Curriculum

Version 1.0/Fall 20102

After this completing this unit, you should be able to:

• Define interoperability

• Describe vendor strategies for terminology and knowledge management, and how these impact interoperability

• Describe processes and requirements for exchanging data with personal health records



InteroperabilityIf I’m faxed a discharge summary which I can read, is that interoperable, since it’s human interpretable? If I’m sent an electronic note via email that notes “Allergy to MS”, is that interoperable? Of course MS could mean Morphine Sulfate, Magnesium Sulfate, or even Minestrone Soup. If I’m sent an electronic message which has an agreed upon format, a standard vocabulary, and a set of business rules which enable me to take action, is that interoperable? i.e. Your patient is allergic to medication NDC Code 123456789. Administration will cause a SEVERE reaction with HIGH CONFIDENCE. My e-Prescribing software could use this information to display a warning alerting me to the issue and could suggest an effective alternative medication.
