  • The EHR contains information which is: 1. retrospective: an historical view of health status and interventions; 2. concurrent: a .now. view of health status and active interventions; and 3. prospective: a future view of planned activities and interventions
  • patients receive more health care the information is more complex a richer variety of examinations, investigations, treatments a greater use of multi-media technologies the information is more important in case of future litigation to justify the use of healthcare resources
  • Scale of the problem University Hospital of Heidelberg: 1700 beds creates about 400,000 new medical records per year containing 6.3 million pages requiring 1.7 km of storage (growing at the rate of 1500m per annum) Physicians create over 250,000 reports and 20,000 procedure reports each year service departments create around a million results {Reinhard, Ohr, et al} {Haux 1998}
  • Separation of EHR context and clinical knowledge: two-level approach Reference Model and Archetypes (approach also adopted by CEN TC/251)
  • FOLDER - The high-level organisation of Compositions within an EHR (or EHR Extract) • An optional hierarchy – Folders may contain other Composition Medico-legal unit of committal in the EHR – When committed, where, by whom Headed section Optional hierarchy • Informal containment for human navigation, filtering and readability • Corresponding to the clinical understanding of Headings ITEM Corresponds to a single clinical &amp;quot;statement&amp;quot; • Required to represent the structure of clinical observations, inferences and intended actions
