It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.įile extension CDA is used for tracks stored on an audio CD. The specs I outlined above suggest that the ONC has too many architects and not enough do-ers.MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression.
I’ve ranted about it before, but developers are key to solving interoperability challenges. At Redox we just ask you for the patient ID, handle the authentication for you, and send you an easy-to-grok JSON Clincal Summary back. ConclusionĪll of the work I outlined to interoperate really only has two inputs: a patient ID and some way of authenticating yourself. Check out my Interoperability Primer to start making sense of that.
Step 6: Understand C-CDAĭid you think that pile of specs was all you needed to read? Not even close – that just gets you an XML document that you need a whole other set of specs to deciper. I’m really grateful they were there for me to do my development, and I don’t sense that policy makers realize how important a good testing tool is to developers. Aside #2 ShoutoutsĪEGIS and NIST did some really great work with these testing tools. Sadly, the options are lacking and not provided by vendors directly.īoth can get you ready to go. Every good developer needs something to test with. Step 5: TestĪssuming you have enough grasp of the documentation, you can start developing. Part of our mission at Redox is to democratize this mess so you only need to worry about inputs and outputs, not the long ugly path in between. will take a lot of work to get you to up and running. Most of the specs you just read were published during the second Bush administration. I put a question mark here because this may or may not be very challenging. Yes, there is exactly one word in the title of the last one.
Step 1: Read specsĮHealth Exchange and Commonwell have specs. The real challenge we are fighting are 10-15 year old technologies that today’s developers shouldn’t need to learn. Epic is no harder to interoperate with any other vendor – they all use the same specs! It’s ludicrous. I hope this post demonstrates the cognitive dissonance ONC has with their interoperability pledge. This article is going to focus on how you would get a CDA document from a network like Commonwell, Healtheway, or just straight from Epic themselves. I thought this an appropriate time to reflect on just how much your developers are going to need to learn to interoperate tomorrow.
#I14YNow is trending at HIMSS and an absurdly vague interoperability pledge has been signed by a bunch of vendors.
