When I was running Google Health I would constantly hear how it was impossible to download health data because of the doctors notes and conditions and lots of fancy stuff that wouldn’t be interoperable. And I agreed. I focused entirely on getting labs and meds to be generally available because these seemed to be the only two things that were computable and not dependent on the vagueries of the hospitals and EHR’s. There is a wonderful post up on on ePatients.net by e-Patient Dave detailing what happens when you try to get more and actually get less. The post is a constant reminder to start small and make sure that what you’re doing works. It is also a reminder that the big systems because they aren’t paid for by the consumers or reviewed by the consumers or ever see the light of day are a terrible mess. Like everything else hidden in the dark, health data is crawling with mistakes. Let’s let the light in!!
