Hi, I am writing my diploma thesis at the Vienna Medical University. I have two questions concerning the openEHR-EHR-OBSERVATION.blood_pressure.v1 Archetype (Date 22/03/2006) and would be very thankful if someone could answer them briefly.
1st: I read in the "The openEHR Reference Model - EHR Information Model" (openehr_ehr_im.pdf Revision: 5.1.0) in chapter "8.2.3.4 Two ways of Recording State" that there are two ways to record States inside a History. In this Blood pressure measurement Archetype they have chosen the way where the state is recorded outside data History. Isn?t it necessary to correlate a blood pressure measurement [at0003] to a position [at0008] (Systolic: 120, Diastolic: 80, Position: Standing)? What is the medical reason for modelling it like that? Even if it is made the other way the problem still occurs with the protocol. When we try to match an Instrument [at0012] (from Protocol) to a certain blood pressure measurement (Systolic: 120, Diastolic: 80, Instrument: XYZ) we don?t know which instrument belongs to which blood pressure. Am I wrong? Is there a way to correlate them? Is there no need to correlate them? 2nd: Why does the "state" begin with an ITEM_LIST[at0007] and not with a History? In the documentation it looks as if "state" and "data" have the same structure.
