Hi Charlie
The issue as to whether a software provider is up to date on their HL7 standards really comes down to what you are trying to do. For HL7 v2.x v2.6 is the latest and greatest. However HL7 is trying to move people onto v3.0 which is a major shift away from the pipe-delimited 2.x standard. However it really all comes down to that systems you are integrating. For example your Lab information system might be using a v2.3.1 message spec while a Clinical Information system such as Cerner or Meditech may be using 2.4. In that case you need to transform the messages from one to the other or pay the vendor to redevelop their message specs (very expensive!). Most software vendors for the Information Systems tend to have a stable spec, but also tend to develop the actual message depending on client requirements.
A messaging platform such as BizTalk from Microsoft helps you manage the integration points by centralising the transformation logic in your organisation to a single place, as well as providing an accelerator to kick start the process.
Perhaps if you provide more specifics I could help give you some more targeted advice?
Cheers
Simon

I am just trying to make sure that the HL7 standards I am following are correct, I think the software that I am using maybe a little out dated, I have been reading articles online about a new versions that are quote up to date, but I was wondering how long i could go without updating the software. I'm sure that would be something that my software provider could tell me. I guess what I really want to know is who is the best software provider, I have CastIron, but I am unhappy with them. I have been looking at Pervasive Software and other providers to see if they are any better. What would be your opinion?

Hi Charlie
Lots of software providers are up to speed on versions of HL7. Can you be more specific? Which versions and messages are you interested in? Whats the issue you are looking to solve?

Has anyone found any software providers that are up to date on HL7 Standards?

Hey Simon, if i remembered to set the “generatedefaultfixednode” to no, I would have saved myself 3 days…of trouble shooting why Visual Studio hangs when validating a map or compiling a project that has complex HL v3 maps. Its documented in the V3 developer guide…and i also ignored it…until I encountered the problem. Each time Visual Studio hang i terminated the session until the third day when I decided to leave it overnight…and next morning i saw the “out of memory error” and my google friend helped me to point back to this documented setting. Ur way ahead of us…here.

Hi, I can configured a MLLP receive port to recive Lab orders. The messages are received by the MLLP port and sent to the BT engine when sent by MLLPSend tool, but no messages are received when sent from the actual application itself. I have used the network monitor to see whether the messages are comming through to the port and they are comming all the time.
any thoughts about this please?

Thanks,
Kishore

As someone new to BizTalk and interested specifically, this was a very informative read – thanks for the information.

Hi Brax

So first off, I have to mention I have never tried calling the BTAHL7 pipeline from code before so this is all conjecture;
The first thing I would check is that the encoding of the string is correct. HL7 messages are “framed” in a particular way and this may be effecting your code. Specifically I would check the way line breaks and carriage returns are encoded and ensure there are no unseen leading characters. I am not sure whether the framing has to be correct in order for the pipeline to be successful. I’ll ask some of my more code orientated friends about this one though and see if I can get you a more specific answer..

With regards to maps; you can include them if you want, but it you are relying on the ACK mechanism you shouldn’t. They do not break provided the inbound message successfully converts to XML. If that fails, the map will fail as the input is not XML as expected. The pipeline will then collapse, and your ACK (or NACK) will not be produced, usually stopping the upstream system until it’s interface is reset.

Cheers!

Hi Simon:

I am trying to execute the BTAHL7ReceivePipeline inside an orchestration, the idea is to take a string variable with the HL7 content and convert it to a BTAHL7 message through the pipeline, this is what i am trying:

HL7Request = string;

BTAHL7ReceivePipeline = Microsoft.XLANGs.Pipeline.XLANGPipelineManager.ExecuteReceivePipeline(typeof(BTAHL72XPipelines.BTAHL72XReceivePipeline), HL7Request);

HL7Request2.MSHSegment = new System.Xml.XmlDocument();
HL7Request2.BodySegments = new System.Xml.XmlDocument();
HL7Request2.ZSegments = new System.Xml.XmlDocument();
BTAHL7ReceivePipeline.MoveNext();
BTAHL7ReceivePipeline.GetCurrent(HL7Request2);

Where ’string’ contains the HL7 content, ‘HL7Request’ is a System.String message i pass to the pipeline and ‘HL7Request2′ is the message i get from the pipeline with the BTAHL7 format.

My problem is that when i execute the BTAHL7ReceivePipeline, it says the following error:

Message has an invalid header, it could be due to error in 1st/2nd field or the segment name is neither MSH nor FHS

Could you help me, please?
