Update Procedure.subject   Description:  On whom or on what the procedure was performed. This is usually an individual human, but can also be performed on animals, groups of humans or animals, organizations or practitioners (for licensing), locations or devices (for safety inspections or regulatory authorizations).  If the actual focus of the procedure is different from the subject, the focus element specifies the actual focus of the procedure.   Add Procedure.focus 0..* Reference (Patient | RelatedPerson | Group | CareTeam | Practitioner | PractitionerRole | Organization) – focus immediately follows subject Definition :  Who is the target of the procedure when it is not the subject of record only Description : Who is the target of the procedure when it is not the subject of record only.  If focus is not present, then subject is the focus.  If focus is present and the subject is one of the targets of the procedure, include subject as a focus as well. If focus is present and the subject is not included in focus, it implies that the procedure was only targeted on the focus. For example, when a caregiver is given education for a patient, the caregiver would be the focus and the procedure record is associated with the subject (e.g. patient).  For example, use focus when recording the target of the education, training, or counseling is the parent or relative of a patient.
