In-Depth Information
•
Sections: They are groupings in a clinical session.
•
Entry: Each one represents a clinical observation or a set of them.
•
Cluster: It is used when the representation of a unique observation or action
requires a complex data structure, like a list, a table or a temporal series.
•
Element: It contains a unique value that must be instance of some of the types
defined by it.
Archetypes
The second model sets the Archetypes [2, 3, 7, 12, 50] as a way to define the clinical
concepts managed by the systems. The archetypes are definitions of sets of clinical
information items, that have a concrete clinical meaning; and they are created using
the components defined in the ISO 13606.
Examples of these archetype may be:
•
Pathological processes: Cataract.
•
Protocols: Pregnancy.
•
Documents: Blood analysis, Radiography and Prescription.
•
Archetype can also be a group of items (biochemistry or lipid information) or a
single item (HDL-cholesterol, LDL-cholesterol or VLDL-cholesterol) in a doc-
ument.
So an Archetype is any information item or group of items related under a clinical
point of view.
However this regulation just sets the basis and general description on which ev-
erything is opened and must be concreted, which is what we do in this paper.

Analysis
As the reader can see, the proposal is developed for machine-to-machine under-
standing, so the goal is to integrate the information on another system inside the
institution EHR system. The proposal means a great efforts of developing and im-
plementation because the complete system has to be change to support the archetype
language so all the information can be exchange. In real situation, medical staff does
not need to access the complete EHR of the patient but a portion of it related to the
act involved. The CEN/ISO 13606 does not achieve this problem and only propose
a translation of data and structure between systems.
The real user of the systems (the medical staff) is omitted from the solution (the
local system will adapt the information sent to the local user). Medical staff does not
need to access the complete EHR but a portion of it, so a complicated structure is not
really needed in most of the external accesses. In that cases, a method to retrieve the
important information needed would be better. In next section we present a proposal
to retrieve this important information and adapt it to the interoperability problem.
