Development and verification of a hypertension guideline encoding model.

For encoding sharable and interoperable guideline knowledge for hypertension management, standard guidelines including JNC7 were chosen. The knowledge modeling process consisted of defining scenarios for describing workflow and identifying knowledge logics. Evaluation of the encoding model was conducted by scenario-based testing. Two experts inverted exclamation mark recommendations were compared with those inferred from the encoding model. The agreement level ranged from 77% to 100%.
