A record of a relationship between a device and the entity to which it is directly associated.

Instance identifier.

Reference to the device that is being associated.

Describes the relationship between the device and subject.

Indicates the state of the Device association.

Administrative or record-management reason for the current DeviceAssociation record status.

State of the relationship between the device and subject.

The entity that is the direct target of the device association. This may be a person, role, organization, location, group, care team, or another device. The subject is not necessarily the patient or ultimate beneficiary of the association. The nature of the association is described by relationship.

When the device is directly assigned to, used by, carried by, worn by, monitored by, or otherwise associated with a caregiver, guardian, family member, or other non-patient individual, a RelatedPerson may be used as the subject. This is appropriate when the RelatedPerson is the direct target of the association, rather than merely participating in the care context of another individual. For example, an alert receiver assigned to a parent on behalf of a child may be represented with the parent as the subject of the DeviceAssociation.

One or more care, organizational, or operational contexts for which the device association exists or is interpreted. Use focus when the subject alone does not fully explain the purpose or context of the association, such as when a device is associated with one entity but supports, monitors, protects, or benefits another. Do not use focus to identify performers, installers, maintainers, or operators merely because they performed an activity involving the device. When different focuses require different relationships, periods, statuses, or traceability, use separate DeviceAssociation instances.

Current anatomical location(s) of the device in/on subject.

Begin and end dates and times for the device association.
