| 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. |
