Multiple insurance segments

[dfelton]

I have a channel's source data as HL7 v2.x ADT with a destination's template also HL7 v2.x. All source messages contain at least one IN1 segment. I am having diffiulty getting Mirth to automatically add more than one IN1 segment to the outgoing data template.

My javascript step looks like this:

var i = 0;
var tempInsuranceCarrierID = ""

while (msg['IN1']['IN1.3']['IN1.3.1'][i] != null) {
	tempInsuranceCarrierID = msg['IN1']['IN1.3']['IN1.3.1'][i].toString();
	if (tempInsuranceCarrierID.length > 0) {
		logger.info(i + ' insurance Carrier ID = ' + tempInsuranceCarrierID);
		tmp['IN1']['IN1.1']['IN1.1.1'][i] = msg['IN1']['IN1.1']['IN1.1.1'][i]
		tmp['IN1']['IN1.2']['IN1.2.1'][i] = msg['IN1']['IN1.2']['IN1.2.1'][i]
                ...
                ...
		}
	i = i + 1
}

When I process a source message with more than one IN1 segment, the output is a single IN1 segment with mutliple sub-fields. In the following output example, the source ADT-A04 had 3 IN1 segments:

IN1|1|100|
IN1|2|100|
IN1|3|100|

...resulting in output:

IN1|1^2^3|100^100^100|

The output is the same whether the index (i) is included and incremented, or not. What am I doing wrong?

Re:Multiple insurance segments

Try putting the [i] in the following place...

tmp['IN1'][i]['IN1.1']['IN1.1.1'] = msg['IN1'][i]['IN1.1']['IN1.1.1']
tmp['IN1'][i]['IN1.2']['IN1.2.1'] = msg['IN1'][i]['IN1.2']['IN1.2.1']

Re:Multiple insurance segments

I've made that change, with the result that this error occurs on source messages with multiple IN1 segments:

ERROR-300: Transformer error
ERROR MESSAGE: Error evaluating transformer
org.mozilla.javascript.EcmaError: TypeError: Cannot read property "IN1.1" from undefined

Additionally, after running a transaction through with multiple IN1 segments, the Mirth log shows this:

destination-transformation: 0 insurance Carrier ID = MEDO
destination-transformation: 1 insurance Carrier ID = MCD

So, at least for the purposes of logging, iterating the repeating segments has worked. It's only when I try to change a template variable that errors occur.

I see in version 1.5 that the incoming and outgoing data template properties for HL7 v2.x have a checkbox for "Handle repetitions". This is checked on both incoming and outgoing. Is that new feature intended to help in this scenario?

Anybody have any clues?

Re:Multiple insurance segments

I know one solution but I wish there were a better one. You have to add a blank segment to the Output Template. For instance I had to add OBX|||||| to the template, then code like:

var i = 0;
var obx = tmp['OBX'];
tmp['OBX'][i] = obx;
tmp['OBX'][i]['OBX.2']['OBX.2.1']="ST";

would work.

Jlehew,
Take a look at my post http://www.mirthproject.org/index.ph...d=4016&catid=2. You should be able to take the concept of that and apply it to the IN1 segment.
Thanks,
