This profile provides an observation information structure for asserting a clinical judgement that there are no items of specific interest, (e.g. no current medications or no history of vaccination), for a patient. An assertion of no relevant finding may be used in continuity of care or transfer or care related lists and composition sections.
Usage:
Description of Profiles, Differentials, Snapshots and how the different presentations work.
