Simple java tool to generate CCDA?

[AJ Chen]

Does Smart server implement CCDA generation?
Or is there any java implementation of generating CCDA from clinical data?
MDHT is too heavy. I hope there is a simpler java code base or tool that I can use for developing BB+ app.
thanks,
aj

Hi AJ,

The SMART Reference Server doesn't have tools for C-CDA generation. 

I certainly agree some lightweight tools would be a real help for the broader health IT community.  I'd be curious what you think a practical interface would look like:  for example, would it take documents in some simpler-to-produce format and "convert" to C-CDA, or would it provide an API with methods like "record.addMedication()" etc.  If the former, what would the simpler format look like?  If the latter, what would the methods be?

Best,

 Josh

Hi Josh,
my use case: my BB+ app needs to get the vital signs and a few common lab results from patient's EHR records.  if I provide a list of tests and vitals, I would like a tool to convert the list to a valid CCDA doc.

Since no such tool at the moment, I'm creating one and will share with the community. It should be pretty easy if I just want to cover the common tests for now. The challenge is how to find the templateId, code, unit etc for each tests that are required by CCDA observation block.  Do you know how to find these information?

thanks,

AJ -
Appreciate your interest in having a "lightweight" api but think you should look on the mdht site as we have protoype some facade and lightweight apis
I am not sure to the extent you think the api is currently too heavy but we do agree that currently the api sitll requires a more indepth knowledge of cda then we would like

mdht is open source and would love to have a friendly api and if you are willing to work on this that would be great

Be happy to walk you through the current project status, prototypes we have and the various model driven approaches to generate the api that can be used

Thanks

Hi Sean,

Thanks for chiming in -- it's great to hear that MDHT has some some lighter-weight tools!  Could you post a link to the "facade API" docs?  (A google search turned up a .docx from 5/2012, but I'm not sure if this is the right resource)

And the following doesn't mention the facade:

http://www.cdatools.com/docs/developeruserguide/org.openhealthtools.mdht.cda.doc.developerguide/topics/topic_MDHTAPI.html

-- are any of these APIs the same as the "facade"

Another thing that would be super-helpful (if it's not already out there) is a standalone, minimal example that uses the Facade API to generate a C-CDA. As in: is there a repository with a sample program that a developer can just "git clone" and then just run "mvn" (or similar) to build a working sample?

Finally, I found this tutorial:

http://www.cdatools.com/docs/developeruserguide/org.openhealthtools.mdht.cda.doc.developerguide/tasks/t_Produce_Goal.html

... but I couldn't find a link to the complete example (with Java import statements, a Main class, etc).

Best,

  Josh

Sean,

I'm building a quick prototype for exchanging ccda using bb+. I was looking for a simple tool, such as a jar file, that I could simply drop in and generate valid ccda from a list of vital signs and lab results. When I have more time, I'll try to set up mdht and learn about it. ccda specs is complex. So, it's great there is comprehensive open source mdht. I'll certainly appreciate your help when I start to dive into the complex world of ccda.

thanks,

I know you have probably long moved on, AJ, but for anyone else coming here via Google and looking for a lightweight tool to generate CCDAs, I couldn't find one I liked when working on MU Stage 2, so I built one and open sourced it as part of the BlueButtonJS project (which is also a great CCDA parser): http://www.bluebuttonjs.com/

It's a Node.js project, but it's pretty easy to use like a command-line utility from a server in another language. It takes JSON as input and requires much, much less knowledge of the CCDA spec than MDHT. It does have the cost that it doesn't cover as much of the spec as MDHT, but it covers all of the MU2 requirements.
