Hi Gustavo, As Heather pointed out, the solution seems to be to reference the internal structure of a device (or any other demographic archetype) through a CLUSTER. But I think those demographic concepts should be also modelled as complete, separate demographic archetypes, referencing the same internal structure (CLUSTER). This allow us (developers) to create functionalities for searching and processing on demographic archetypes.
About the internals of a test, I think most often includes both ACTION and OBSERVATION, because an ACTION could be used when you need to record information about the execution itself (being or not a clinical intervention on the patient, e.g. the recording of the device used to make the test should be part of the ACTION not of the OBSERVATION), then the OBSERVATION(s) could hold the information about the test result or information about clinical findings during the test. Then the whole record of a test execution should be recorded into a COMPOSITION that references those ACTION(s) and OBSERVATION(s). The INSTRUCTION of a test could reference to a device that should be used on the test, but during the test maybe another device was used, and that should be part of the ACTION that executes the INSTRUCTION. Does this makes sense to you? Please correct me if I'm wrong. My student detected some oftalmologic concepts that are not in the CKM, maybe I can put you both in contact to collaborate on the modelling of those concepts. -- Kind regards, Ing.

To: openehr-clinical at lists.openehr.org Hi Pablo,I'm an ophthalmologist and would be gladful to help. There are some issues about the archetype class and the nature of the test. As it is a study test it must be considered the existence of an intervention. If it does not include, so the most appropriate would be to record as an OBSERVATION archetype for the test. If it includes an intervention, then the most appropriate is to record as ACTION. For both situations use the "Device" CLUSTER on the CKM to record the device, remembering this archetype is not adequate to record a substance (e.g. fluorescein). To record the device that should be used for the test at an INSTRUCTION archetype, also consider the element "Description of Procedure" of "Procedure Request" archetype on CKM, which could be used to specify the device. I hope it was helpful.-- Gustavo BacelarMD + MBA + Med Informatics gustavobacelar.com+351 91 203 2353 +55 71 8831-2860Skype: gustavobacelar _______________________________________________ openEHR-clinical mailing list openEHR-clinical at lists.openehr.org http://lists.openehr.org/mailman/listinfo/openehr-clinical_lists.openehr.org -------------- next part -------------- An HTML attachment was scrubbed...
