Hello Muhammad

Your question is a little bit vague, so here are a few possible answers:

> i develop openEHR observation extract and how can i use raw data with it???

1) To develop an openEHR OBSERVATION Archetype you would need to familiarise yourself with the openEHR Archetype editor (http://www.openehr.org/svn/knowledge_tools_dotnet/TRUNK/ArchetypeEditor/Help/index.html).

2) If you are looking for a relevant data file in some format (e.g. XML) that conforms to some OBSERVATION Archetype then the easiest thing would be to have a look into this ZIP archive (http://www.openehr.org/wiki/download/attachments/33619970/openEHR-composition-instances-LiU-2012-05-14.zip?version=1&modificationDate=1336988776000) by Erik Sundval which is available in this article (http://www.openehr.org/wiki/display/dev/Development+test+base)

3) To do it from scratch, that is, to take the specification of some OBSERVATION Archetype, populate it with data and save it, is a longer and a little bit convoluted process whether you do it "manually" or through software. Therefore, before getting into that you need to be clear on what you are trying to do and what you want your end-result to be.

Prior to doing this, you would also need to have familiarised yourself with the following documentation (at least):
a) http://www.openehr.org/svn/specification/TRUNK/publishing/openEHR/introducing_openEHR.pdf

b) http://www.openehr.org/svn/specification/TRUNK/publishing/architecture/overview.pdf

c) http://www.openehr.org/svn/specification/TRUNK/publishing/architecture/am/archetype_principles.pdf

Taken from this web page with much more information: http://www.openehr.org/svn/specification/TRUNK/publishing/roadmap.html

I hope this helps

All the best

Thanks a lot for your kind reply. Let me rephrase my question…

Hello,

I am in process of creating an exchangeable EHR Extract between two different HMIS. Here is what I want to do and requires guidance

  1. I have data about patient encounter, that includes Patient Demographics Information, Hospital Information, Physician Information and Clinical Observations
  2. The clinical observations are gathered and registered in the form of SOAP and SOAP archetype is available from CKM
  3. Now I know in order to represent patient demographics, hospital information and physician information I have to use Demographics Information Model
  4. The observations includes Blood Pressure, Cholestrol, Haemoglobin, Lipid, Height, Weight etc. I saw archyetypes for some of them as well. And I know that observations are handled in EHR Information Model.
  5. The structure to all these requires that I create and EHR Extract using all the above information.
  6. Using openEHR API, I want to create a system that should generate automatic EHR Extract when I provide it with the patient’s encounter information

In order to address this issue I will be grateful if someone help me in answering the following queries

  1. I am unable to understand how to use the already available archetypes and embed clinical information for generating EHR Extract

  2. The use of API or some documentation or tutorial of how to use the openEHR API for generating EHR Extracts using clinical data

  3. How to relate archetypes with extracts.

I would appreciate if for understand the real essence of openEHR, a small tutorial is provided in which clinical data, archetypes and finally extract generation is shown.

Kind Regards,

Hello,

On the basis of suggestion of openEHR family I initially created archetypes (reused some of the existing ones as well after modifications). Afterwards, I created template based on the different archetypes. Now comes the question, how can I use this template for recording data entries and also generating the openEHR native format for exchange of this information. For example, if I want to develop a prototype healthcare system compliant to openEHR, where my requirements are to generate openEHR extract from the data stored in database and a template already created for it. I would be grateful if provided with a kick-start so that I can move forward from the loophole.
