# Device information in the EHR **Category:** [Clinical (archive)](https://discourse.openehr.org/c/clinical-archive/153) **Created:** 2007-08-31 00:35 UTC **Views:** 1 **Replies:** 6 **URL:** https://discourse.openehr.org/t/device-information-in-the-ehr/14664 --- ## Post #1 by @Sam Hi Everyone I have just returned home after many weeks of meetings which have been an extraordinary experience - but one involved a session at the ISO meeting in Brisbane with the devices group and Melvin Reynolds. He is interested in standardising the information we keep about the device as part of the observation protocol. We have agreed to try and get a standard model (a cluster in openEHR) that we use to record information about the device used to make the observation. It was raised at the meeting that the laboratory will retain a great deal of information - the point is that some of this might be critical in the future (such as the identification of the device if systematic errors are later reported which might mean we should not accept the findings from this device as sufficiently accurate). I would like to start a thread where we agree on the information about the DEVICE - this is not about the value (ie the accuracy of the measurement can be added to the reading and should be there we believe) - so it is about the device itself. What do people suggest? Cheers, Sam Heard --- ## Post #2 by @David_Rowed Sam, Are we talking mainly laboratory devices or all types of diagnostic and monitoring including imaging and home-based devices? --a tall order if the latter. Various HL7 TCs and SIGs including LAPOCT would be a starting point for the content and some of the use cases. Archetypes authored by the people with the need should protect the mainstream from this quagmire. David. --- ## Post #3 by @Colin_Sutton To keep it simple, the minimum information on a device should include: - Device Name - Device Description (purpose) - Manufacturer - Model Identifier - Serial Number [may be N/A] - Firmware version [may be N/A] Other information could be included: - Service Date(s) - Modifications or adaptations, - Associated or connected devices- Distributor - Location Regards, Colin Sutton IT Systems Development Manager NHMRC Clinical Trials Centre [http://www.ctc.usyd.edu.au](http://www.ctc.usyd.edu.au/) -----Original Messag e----- --- ## Post #4 by @Philippe_AMELINE Just some field information for endoscopic and echographic reports\. For endoscopic exams, we are used to writing : Device type, Manufacturer, Model, Serial Number \(for endoscopes tracability\) Example: Colonoscope Pentax HR200 s/n 234EB22 But, for practical reasons, don't forget that users don't always know the s/n and usually are using other way to locally select a material \(for example "blue mark" or the first or last letters of the s/n\)\. For echographic exams, it is usually Device type, Manufacturer, Model and Service date \(to indicate recentness\)\. I am not aware of recording sub\-devices \(like echography probes\) information\.\.\. even if this is an important part and the one that "touch" the patient\.

(there are a few more but this is certainly one) The CEN/ISO/IEEE devices community has tackled interoperability for quite some time. As far as I know that are very familiar with the principles behind the CEN/ISO EN13606 and use it even to make devices 'plug-and-play' interoperable.

Could you give me specific detials on your comment \- "The method HL7 deploys has its problems and drawbacks as many are discovering or have discovered\."?
