  • Archtectural Overview Aims

    1616Because the architecture is highly generic, and particularly due to being archetype-driven, it satisfies many requirements outside the original concept of the "clinical EHR". For example, the same reference architecture can be used for veterinary health or even "care" of public infrastructure or listed buildings. This is due to the fact that the reference model embodies only concepts relating to "service and administrative events relating to a subject of care"; it is in archetypes and templates that specifics of the kinds of care events and subjects of care are defined. In another dimension, although one of the requirements for the openEHR EHR was a "patient-centric, longitudinal, shared care EHR", it is not limited to this, and can be used in purely episodic, specialist situations, e.g. as a radiology department record system. Requirements for various flavours of "health care record" can be categorised according to the two dimensions, scope, and kind of subject, as shown in FIGURE 2.

    2020In this figure, each bubble represents a set of requirements, being a superset of all requirements of bubbles contained within it. Requirements for a generic record of care for any kind of subject in a local deployment are represented by the top left bubble. The subsequent addition of requirements corresponding to living subjects and then human subjects is represented by the bubbles down the left side of the diagram. The requirements represented by the largest bubble on the left hand side correspond to "local health records for human care", such as radiology records, hospital EPRs and so on. Additional sets of requirements represented by wider bubbles going across the diagram correspond to extending the scope of the content of the care record first to a whole subject (resulting in a patient-centric, longitudinal health record) and then to populations or cohorts of subjects, as done in population health and research. From the (human) healthcare point of view, the important requirements groups extend all the way to the bottom row of the diagram.
