David uses the NHIN subject and data locator services offered in his EMR to discover that Joe has EKG data at Hospital B using a machine that is appropriate for evaluation by his new knowledge module. He makes a request to be given permission to evaluate the EKG data using his own local signal averaging criteria. Upon receiving authorization, DDSS A sends DDSS B the knowledge module. DDSS B then executes the rule, generates the result, logs the activity, and returns the requested evaluation back to DDSS A which then displays the results. David then concludes that Joe does indeed show evidence of conduction abnormalities and signs off on the recommendation for a treadmill evaluation placed in the system by DDSS A.
