CPRS New Order (lab) pending status and ORM HL7 message

[Alex Vazquez]

Hi,

I was able to setup my VistA docker image and CPRS successfully.

I would like to setup a new Logic Link TPC 6661 for ORM messages, so I think I already created my Logic Link in the VistA terminal and then I went to CPRS and created a new Lab order (CBC Without Diff) and signed. I can see it in the list but it appears as pending, I guess at this point I should see some ORM message but I think I tried to lookup for the messages in the terminal and the last message is from a few years ago so it's from the default data in the docker image.

Is there anyone that can guide me on the steps to setup this flow? My goal is to get an ORM message to a custom logic link and then also set a new logic link so that I'm able to send the results to the ORU message.

Appreciate any help,

Best,

Alejandro

This is usually paid consultation territory, but you are lucky in that OSEHRA supported me previously to develop an HL7 set-up guide: https://hardhats.org/projects/New/SetUpHL7.html. See if that can help you. I don't know much about specific HL7 messages in the lab package, but it looks like you have that part figured out.

Also, as FYI, see https://github.com/shabiel/HL-GTM if you need to get HLO running on the Docker Image. Most of VistA uses the classic HL7 package.

Hi Sam,

Appreciate it so much. I will study the guide and will try to follow the sample steps to see if I can get it working that way.

Much appreciated it 🙏

Best, 

Alejandro
