A current health summary is what lets any clinician pick up a patient safely. For each active patient the practice records known allergies, or that there are none known, in the designated field of the record so that the software can alert prescribers. The record also carries an up to date health summary covering, where relevant to the patient, adverse drug reactions, the current medicines list, current health problems and relevant past history, immunisation status, family history and social history, reviewed and updated at consultations. The practice audits summary completeness and works to raise it.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
