Its second phase integrated a personal health record (containing diagnoses and treatments), with the national appointment system, for planned elective care. Importantly, EDUS also contains a “family” record for each individual, systematically recording broader determinants of health and well-being, such as other family members with complex illnesses, and any financial or housing difficulties. This allows a fuller assessment of the individual’s needs, as well as enabling local population health profiles to be built, and needs predicted. Future development will link EDUS to digital imaging, laboratoiy records, pharmacy records and in-patient clinical notes (nursing as well as medical).
