Health Level Seven


HL7 has recently announced the availability of new version of The Arden Syntax for Medical Logic Systems. This ANSI-approved American National Standard is a language for representing and sharing medical knowledge among personnel, information systems and institutions and designed for organizations that require or develop systems that automatically assist physicians in decisions and alerts.

The logic for making these decisions or issuing these alerts is encoded into health knowledge bases called Medical Logic Modules (MLMs) each of which contains sufficient knowledge to make a single decision. Contraindication alerts, management suggestions, data interpretations, treatment protocols, and diagnosis scores are examples of the health knowledge bases that can be represented using the Arden Syntax.
