Hi Athanassios, re 4b of your issues list you can take a look at our project which is open source. It is a .Net desktop app for endoscopy reporting. Not a full EHR application but may give you an idea about data model, binding and especially GUI design which we followed MVC approach.
http://gastros.codeplex.org It uses open source .Net openEHR RM and AM which has recently been contributed by Ocean Informatics. Here are two short papers describing in detail our implementation (you can download both from project website). - Atalag K, Yang HY, Warren J. On the maintainability of openEHR based health information systems - an evaluation study in endoscopy. In: Proceedings of the 18th Annual Health Informatics Conference, HIC 2010. Melbourne, Australia: HISA; 2010 p. 1-5?? - Atalag K, Yang HY. From openEHR Domain Models to Advanced User Interfaces: a Case Study in Endoscopy. Wellington: 2010? That said if you are looking at more generic implementations of openEHR I suggest that you look into Opereffa project which is a reference implementation framework and also the Java reference implementation. http://www.openehr.org/projects/opereffa.html http://www.openehr.org/openehr/projects/java.html Hope this helps...Please do not hesitate to ask further questions. Cheers, -koray From: openehr-clinical-bounces at openehr.org [mailto:[email protected]] On Behalf Of Athanassios I. Hatzis, PhD Sent: Thursday, 17 March 2011 9:09 p.m. To: 'For openEHR clinical discussions' Cc: 'Openehr-Technical' Subject: RE: openEHR future directions Hi Thomas, I read your email and I would like to comment on the three main topics you touched. First I believe that people in openEHR project have contributed a lot in all three areas of health informatics as you mentioned in your email and congratulations to all for leading innovative work. Nevertheless in my opinion what makes openEHR to excel in the domain of health informatics and where I certainly place my bet for the future is the design of archetypes and especially templates. This is THE bridge between health professionals and software developers. You can find tons of specifications from all the organizations you referred to and you can also find a lot of open source software tools and applications in the health domain but the simplicity of archetypes and templates and the tools to design them is unique in your project. Nevertheless the last two years I have been pondering a lot on the state of the art regarding the design of graphical user interfaces, the design of the data model and the trend to support distributed systems with web services. This is certainly not the place to get into great depth about the technical details on all these but I am more than happy to present you my research plan and perhaps you can provide me with answers or directions on the OPEN design principles that you followed in your project in order to cope with the following issues: ? 1. Data model (I am referring to your UML RM model) - Archetypes and templates a. What database model are you using for the permanent storage of your entities, is that implemented on a popular DBMS, is it open ? b. How do you connect the database model with the programming data model and your ADL structures, what kind of OR mapping are you using c. Why are you using ADL and not standard XML-XSD to describe your archetypes, templates ? d. Have you explored the path on how your knowledge representation is linked to popular W3 technologies such as ontology, linked data, RDFs, especially the application of these on media information management ? ? 2. Design of user interfaces, how is openEHR linked to the following a. What principle you follow when you bind your data to the GUI component ? b. Is there a particular model you are following on the design of applications (e.g. MVC ?) c. Have you considered to support popular document formats such as Office Open XML and Open Document Format ? d. How easy is it for a developer to embody openEHR technology with popular frameworks (Adobe Flex, Microsoft .NET) ? ? 4. Distributed systems and services a. Considering the major acceptance of the standard clinical documents (CCR, CDA) in the health domain and the impact they have on the interchange of data information, how do you match or implement those in openEHR ? b. Is there an open demo of a complete prototype that one can explore to see openEHR in action (common scenario includes a clinic with doctors and patients where the user can explore health records for each one of them as well as services provided by the system) ? ? I am sure that you have explored all these but I think it makes sense to see how exactly openEHR is going to fit with the big trends of information technology (i.e. databases, user interface modeling, web services - semantic web). ? Best luck with your efforts ? Athanassios Hatzis http://medilig.org http://athanassios.gr PS: I do not read the technical list of openEHR as I do not have the time to get into great depth of details for openEHR implementation. But I am very keen on the architecture design principles and plans you have for the future.
