Hi Erik, Both the Service request archetype and the Laboratory archetype and their associated families of archetypes are currently under review and therefore it is a bit messy at present.
Service request is currently under review and evolving. Request for Procedure has been identified but is currently out of alignment as the parent archetype evolves. Whether other more specific ones for Lab test or imaging is required will be determined based on the final INSTRUCTION.request.v0 pattern and whether there is a need for further specialisations, mainly to support querying, I suspect. Laboratory test/Lab test archetypes are in flux. They are complicated and the base OBSERVATION for the results needs to go out for review ASAP. The patterns for specialised lab test categories for histopathology, microbiology, immunology, cytology needs special attention – I’m not sure if Ian has a recommendation for how these will evolve yet. More specific comments inline. Regards Heather From: openEHR-clinical [mailto:openehr-clinical-boun...@lists.openehr.org] On Behalf Of Erik Sundvall Sent: Monday, 11 April 2016 12:02 AM To: For openEHR clinical discussions <openehr-clinical@lists.openehr.org> Subject: Templates and archetype patterns for PVC usage, emergency wards etc? Hi! Does anybody want to share templates or other documented patterns on how to set up recording of some things useful in emergency wards etc? Some examples: 1. Peripheral venous catheter<https://en.wikipedia.org/wiki/Peripheral_venous_catheter> (pvc) usage (ordering of insertation, insertation, removal) etc? From reading archetype metadata in the openEHR CKM one can guess that one way is to use the very general openEHR-EHR-INSTRUCTION.request-procedure combined with openEHR-EHR-ACTION.procedure and create appropriate attribute naming in templates/forms. Is that a commonly used approach? [HVL] This is the way I would do this, Erik. The PVC can be described in detail using the Medical Device archetype (CLUSTER.device) – specified in the INSTRUCTION if necessary and the exact details of what was inserted in the ACTION. Otherwise we will end up with multitudes of specific instructions and actions for every type of procedure etc. Let’s leverage terminology. The only caution I’d say is to ensure that the ACTION is specific enough 2. For ordering and administration of fluids and/or medications both through pvc and other ways I guess this combination could be used: openEHR-EHR-INSTRUCTION.medication_order.v0 openEHR-EHR-ACTION.medication Is that correct? [HVL] Agree that Medications will be ordered and the ACTION recorded separately and the latest Medication INSTRUCTION currently under review does have capability to be administered via PVC. We don’t currently have IV fluid administration orders/actions as separate archetypes at this point eg for rehydration etc via PVC – are you needing this? Is there anything else that is usually needed for handling this? Any example templates out there? 3. Are there any documented templates/patterns covering the ordering the sampling of tests (blood tests etc),record actual test sampling, response from lab etc? Is it openEHR-EHR-INSTRUCTION.request-lab_test.v1 for the first things and openEHR-EHR-OBSERVATION.laboratory_test.v0 for the results? The openEHR-EHR-OBSERVATION.lab_test.v1 and its specializations seem older, are they considered legacy or something to use for new environments? [HVL] The lab test archetypes are currently undergoing revision – you are absolutely correct. The latest candidate for an OBSERVATION to carry the laboratory test results is here: OBSERVATION.laboratory_test.v0 http://www.openehr.org/ckm/#showArchetype_1013.1.2191. The OBSERVATION.lab_test will likely be made obsolete once this newer archetype goes through a successful review process. The current pattern of specialisation for each common blood test is likely to become redundant as the analyte results, panels etc will be carried as a nested CLUSTER within the ‘Test findings’ SLOT. So the future pattern will support generic CLUSTER archetypes driven by terminology (plus probably a lesser number of very specific and explicit CLUSTER archetypes (TBD)) to be nested within the OBSERVATION to cater for the varying levels of detail and huge scope of tests. For the request, the generic Service Request (INSTRUCTION.request.v0) is currently being investigated to be the pattern for all types of request, using terminology for service name, and ‘Service type’ if necessary to specify laboratory or even Micro etc. This archetype is still undergoing review and so if this does not fulfil this purpose for you, please let us know of the additional requirements you identify. openEHR-EHR-INSTRUCTION.request-lab_test.v1 will most likely be made redundant if the generic Service request covers the requirements OR it is possible a specialisation of the new Service request (INSTRUCTION.request.v0) archetype may be developed if required after the parent is published or if there is a preference to have one to support specific querying . 4. Are there any emergency room/ward templates out there that can be shared? I have started a wikipage at... https://openehr.atlassian.net/wiki/x/BAB8Ag ...where example templates and design patterns could be shared informally. If you find it easy to add things in a wiki, then please do, if not then mail examples to me at erik.sundv...@regionostergotland.se<mailto:erik.sundv...@regionostergotland.se> and I'll upload them there. Examples in non-english languages are also useful - I think the patterns are visible anyway. Best regards, Erik Sundvall Ph.D. Medical Informatics. Information Architect.
