I think people still need to know what is OpenEHR :

What is OpenEHR?

When talking about interoperability in healthcare, the key problem lies in how data is written in the first place. Universal interoperability could be achieved if all doctors recorded data in the same structure. This is a very generalized description of what openEHR is: an agreed set of forms for different specialties, defined by surgeons for surgery needs, cardiologists for cardiology needs, and so on. OpenEHR is not a standard for engineers but a standard for medical professionals.

As stated on openehr.org »OpenEHR is a virtual community working on means of turning health data from the physical form into electronic form and ensuring universal interoperability among all forms of electronic data. The primary focus of its endeavour is on electronic health records (EHR) and related systems.«
The idea of a global EHR
In a previous post I shortly touched upon interoperability. Well, in an ideal world, interoperability would not be important at all. Can you imagine a one ubiquitous EHR system all over world that serves all mankind? In this scenario, every one of us would have access to their medical data at any time and any location. But as we all know, the reality is so far from this utopian dream (at least for now).

Lock-in based business models as the unfortunate reality in healthcare!
Medical records management systems have traditionally been developed by software developers that typically designed a database and a user interface on top of it in order to support the work processes of healthcare personnel. And as time passed by, they were doing business as usual and introduced changes to the data model and to the user interfaces. And developers were the ones who knew what the data model actually means. Even more, these data models were not owned by healthcare organizations but by the software companies — in spite the fact that healthcare organizations are typically the owners of the data they produce. So imagine what you can do with raw data without the data model schema that tells you what this raw data really means!
