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 Bacelar MD + MBA + Med Informatics gustavobacelar.com +351 91 203 2353 +55 71 8831-2860 Skype: gustavobacelar -------------- next part -------------- An HTML attachment was scrubbed...
