Primary care patients in the emergency department: Who are they? A review of the definition of the ‘primary care patient’ in the emergency department

Abstract Objective:  To review the definition of ‘primary care’ and ‘inappropriate’ patients in ED and develop a generally acceptable working definition of a ‘primary care’ presentation in ED. Method:  A Medline review of articles on primary care in ED and the definitions used. Results:  A total of 34 reviewed papers contained a proposed definition or comment on the definition for potential ‘primary care’, ‘general practice’, or ‘inappropriate’ patients in ED. A representative definition was developed premised on the common factors in these papers:•  Low urgency/acuity – triage categories four or five in the Australasian Triage Scale •  Self‐referred – by definition, patients referred by general practitioner/community primary medical services are not primary care cases because a primary care service has referred them on •  Presenting for a new episode of care (i.e. not a planned return because planned returns are not self‐referred) •  Unlikely to be admitted (in the opinion of Emergency Nurse interviewers) or ultimately not admittedDiscussion:  This definition can be applied either prospectively or retrospectively, depending on the purpose. Appropriateness must be considered in light of a legitimate role for ED in primary care and the balance of resources between primary care and emergency medicine in local settings.
