How can I setup and use a template HL7 message?

Question

I want to create an HL7 message from a csv file, database query, or some other source other than HL7.

Answer 1

One method would be to create a system variable to be used as the template.

MSH|^~\&|sender|sender|recipient|recipient|{SYSTEM_DATE[yyyyMMddhhmmss]}||MDM^T02|{UUID-NO-DASHES}|P|2.3|||NE|NE

EVN|T02|{SYSTEM_DATE[yyyyMMddhhmmss]}

PID|1||123||FakeLastName^FakeFirstName^^||19500101000000|M|||||||||||111551234|||

TXA|1|CM|TX|20130127142151||||20130127142151||||{UUID-NO-DASHES}||994|||AU|UC|AV|||^^^^^^^^^^^^^^20130127142151

OBX|1|ST|||Discharge|||||||||20130127142151

Then create a custom mapping function that creates your HL7 message and sets the value to the above template.

 

message = qie.createHL7Message();

message.setNode('/', qie.evaluateTemplate(qie.getVariable('templateHL7')));

I completely agree that this is the easiest and simplest way. If a segment conditionally needs to exist in the message, then you will need to supplement the message using functions like message.addChildAfter().
