Dear Koray, I am currently doing a PhD research on the topic of EHR Semantic Interoperability. So I am also very interested in formal ways of measuring system interoperability. As you have discovered, I also found relevant literatures are very few. But we could look for similar ones in other sectors.
I think for measuring interoperability one needs to investigate how the system can exchange information with other systems and use exchanged information effectively. In EHR specifically, it will probably mean we need to look into how EHR can work together with other EHR systemes and surrounding systems, e.g Patient Administrative System, Decision Support System and Quality Registries etc. Regards, Rong On Feb 11, 2008 10:40 AM, Koray Atalag <atalagk at yahoo.com> wrote: > Dear All, > > I started this thread to get some feedback for finding methods/metrics > to test & validate maintainability and interoperability (of Archetype > based two-level apps).
