Batched HL7 messages over tcpip

[David Dillard]

Hi,

One of our clients sending us HL7 order messages ove a tcp/ip VPN connections is sending us messages in the following format:

Code:

BHS
  {
 MSH
 PID
 ORC
 OBR
 }
BTS

Normally when we are working with tcp connections we just receive the single message — and have only seen the batch segments when working with files.

What would be the best way to handle this?  

Is there a special pdl to use for the communciation? we normally use a mlp_tcp.pdl OR would a modification to the inbound tps proc used to send back the ack message be in order here?

If anyone has experience dealing with this I would love to hear from you.

Thanks greatly,

Haven’t ever faced this .. but ..

I suggest an inbound TPS, which will then split up the ‘batch’ into multiple messages, and CONTINUE each message.

You won’t be able to use Cloverleafs parsing…. until you split it into multiple messages.

(But why would you want to any way!)

We’ve done that with a Physician interface. You will need to strip off the BHS and BTS segments in an inbound TPs. It will be your choice to then split through each individual message in either the same TPs or create another one and stack it on the inbound TPS proc.

Not to difficult either way. Good luck to you.

I just needed look in the right direction.

Once I took a look at the inbound TPS we currently use to ack the client it all became clear.

Thanks everyone for the guidance 😀
