Thank you Andrew for your clearification. I was wondering whether I could do both storing EHR and sinple DS through the archetypes therefore I was looking for the calculation field etc. etc. This means that EHR must be linked with separate DS engine. This helps heaps for my thesis. Regards, Pratima

Pratima, I don't think anyone is suggesting that decision support wouldn't be delivered at the pointy end of the clinical process, just that archetypes aren't the best spot to define the decision support. Archetypes really are about the "data" that can be stored - by defining the types of data, the meaning of the data and the rules which say whether the data is valid. The archetype shouldn't define what happens when the data matches a certain condition. So in the case of your alcohol protocol The system would define an archetype "AlcoholEval" with - a perspiration criteria (defined to be a number between 0-4, potentially with bindings to external terminology to give the numbers more universal meaning) - a tremor criteria (defined to be 0-3 etc) - a protocol score (defined to be an integer between 0-7, with an invariant in the archetype starting that it is the addition of the other scores) Some user interface would be presented to the clinician to allow them to fill this data in. Elsewhere, a decision support engine would have some rules that says if I encounter a "AlcoholEval" archetype, to recommend different actions. 1. mild - continue 4 hrly observation 2. Mod. - Oral diazepam such dose and such interval 3. Severe: IV diazepam such dose and such interval But the standards for defining formats for protocol guidelines and interoperable decision support engines are still a way off (i.e. your local implementation of openehr will probably have a way of doing this decision support but its not part of the standard). (btw this is my understanding of the situation - others with more clinical expertise or openehr expertise may disagree :) Andrew _______________________________________________ openEHR-clinical mailing list openEHR-clinical at openehr.org http://www.chime.ucl.ac.uk/mailman/listinfo/openehr-clinical Pratima Poudel Acharya http://sagarmatha.freewebpage.org/ __________________________________________________ Do You Yahoo!?
