  Code	Display	Definition
  NOT	ugent notification contact	An information recipient to notify for urgent matters about this Act. (e.g., in a laboratory order, critical results are being called by phone right away, this is the contact to call; or for an inpatient encounter, a next of kin to notify when the patient becomes critically ill).
  PRCP	primary information recipient	Information recipient to whom an act statement is primarily directed. E.g., a primary care provider receiving a discharge letter from a hospitalist, a health department receiving information on a suspected case of infectious disease. Multiple of these participations may exist on the same act without requiring that recipients be ranked as primary vs. secondary.
  REFB	Referred By	A participant (e.g. provider) who has referred the subject of an act (e.g. patient). Typically, a referred by participant will provide a report (e.g. referral).
  REFT	Referred to	The person who receives the patient
  TRC	tracker	A secondary information recipient, who receives copies (e.g., a primary care provider receiving copies of results as ordered by specialist).
  IRCP	information recipient	A party, who may or should receive or who has recieved the Act or subsequent or derivative information of that Act. Information recipient is inert, i.e., independent of mood." Rationale: this is a generalization of a too diverse family that the definition can't be any more specific, and the concept is abstract so one of the specializations should be used.
