ISO 21090 FDIS approved

ISO 21090, “Healthcare Data Types” has passed the final ballot cycle (known as FDIS – Final Draft Information Standard). It’s been a long 8 year saga since Charlie McCay and I first imagined it, and realised that the long stand-off between CEN/ISO and HL7 regarding data types could be resolved.

While I carried the editorial load, there’s a lot of people to thank. Charlie McCay was as much responsible for the initial idea as me. I received substantial contributions concerning the details of the specification from Paul Biron, Lloyd McKenzie, Gunther Schadow, and Tom Beale (note, though, that the latter two are distinctly unhappy with the outcome). Richard Dixon-Hughes, Ed Hammond, Dipak Kalra, Melvin Reynolds, and Woody Beeler all contributed greatly to shepherding the specification through the tricky multi-committee process.

Institutionally, the English NHS (Connecting for Health) helped greatly to get the project off the ground (thanks Ken Lunn and Ravi Natarajan), and there was enthusiastic support from the National Cancer Institute and also the National e-Health Transition Authority here in Australia. Finally, my employer at the time, Kestral Computing was gracious enough to allow me to work on it on their time.

Now the process starts all over again….

About Health Intersections

Health Intersections is the consulting company of Grahame Grieve. I specialize in healthcare interoperability, balancing clinical, management and business perspectives with a deep technical knowledge and capability.

For many years, I was CTO for Kestral Computing P/L, where I provided leadership with regard to development methodology, strategic technologies, enterprise architecture, and standards and interoperability, and conceived, developed and sold interoperability and clinical document solutions and products. As part of this work, I became deeply involved in healthcare standards, principally HL7 and ISO, and for nearly a decade I have used committee chair positions and editorship of key structural standards to lead convergence between US and European standards organizations.

In addition, I am involved in a number of open source industry consortiums: Open Healthcare Framework, Open Health Tools, and the Indy Project.

I live in Melbourne, Australia and can be contacted at
