Dealing with Data in Repeating Segments

[bdilworth]

Hi All!

I have a couple of questions that are probably pretty basic but I'm having a heckuva time trying to figure out how to get Mirth to do it.

1. What is the "proper" technique for extracting things from incoming HL7 repeating segments and placing a subset of those extracted things into repeating segments in the outbound HL7 message? Does anyone have any working examples they'd be willing to share?

2. Can data extracted from the incoming message via javascript be inserted directly into the outgoing message without resorting to the use of variables in the outgoing message template??? If so, how do you do this? Again, does anyone have any working examples they'd be willing to share?

Thanks in Advance!!!!!

Can you post a sample message that we can reference?

Reealing with Data in Repeating Segments

Hey Bob D!

I've done this things with "Javascript" type of transformer on outgoin' connection.

All you have to do is create a loop of existing HL7 segments and mae new segment out of this!

Example:

var count = 0;

for each (dg in msg..DG1){

	
	tmp['seg3']['rpt'][count] = msg['DG1']['DG1.4'][count].toString();
	
	count++; 
}

So, my goal was create XML message from HL7 message with all DG1-4 values.
I added sample XML structure to Outgoin' tab.

<seg1>
  <rpt></rpt>
</seg1>

That's it! I get that much <rpt> segments, as much is DG1 segments in incoming message!


Hope that helps!

Hi Oleg!

Thanks for response!!!!!

I'll give it a try and let you know what happens.

Reealing with Data in Repeating Segments

OK, well I FINALLY figured this out!!!! It was a real D'Oh! moment, let me tell ya.

My mistake was using a destination template with the outbound HL7 message in it like this:

MSH|^~\\&|PCM|A|XYZ|A|${msh7}|OkToBundle|${msh9}|${msh10}|P|2.2|||AL|NE${cr}PID|1||${pid3}||${pid5}||${pid7}|${pid8}||||||||||${pid19}|${pid19}||${cr}PV1||I|6CD^6152^01^A^|3|||51372^AKPUNONU^BASIL^^^^MD|51372^AKPUNONU^BASIL^^^^MD|""|RHB||||1|||51372^AKPUNONU^BASIL^^^^MD|IR|0710100001^^^A|PP|||||||||||||||||||A|OCC^OCCUPIED||||200704110910|||||${cr}DG1||${holder}||TEST||ADMITTING||||||||

I couldn't get the repeating segments to actually repeat. I suspected that I was overthinking things (which I tend to do a lot). It suddenly occurred to me that, rather than putting the ACTUAL HL7 in the destination template (as above), perhaps all I need to do was use ${message.encodedData} in the destination template and use my javascript step in my transformer to insert the variables into the outgoing message area like this:

tmp['MSH']['MSH.7']['MSH.7.1'] =  $('msh7');

Damn if it didn't work!!!!!! For grins, and for anyone having similar troubles, here's the javascript step in my transformer:

var count = 0;
tmp['MSH']['MSH.3']['MSH.3.1'] = "PCM";
tmp['MSH']['MSH.5']['MSH.5.1'] = "XYZ";
tmp['MSH']['MSH.7']['MSH.7.1'] =  $('msh7');
tmp['MSH']['MSH.9'] = $('msh9');
tmp['MSH']['MSH.10']['MSH.10.1'] = $('msh10');
tmp['PID']['PID.3'] = $('pid3');
tmp['PID']['PID.5'] = $('pid5');
tmp['PID']['PID.7']['PID.7.1'] = $('pid7');
tmp['PID']['PID.8']['PID.8.1'] = $('pid8');
tmp['PID']['PID.19']['PID.19.1'] = $('pid19');

for each (dg in msg..DG1)
{
    logger.info('dg.1: ' + msg['DG1'][count]['DG1.1']['DG1.1.1'].toString());
    logger.info('tmp dg.1: ' + tmp['DG1'][count]['DG1.1']['DG1.1.1']);
    tmp['DG1'][count]['DG1.1']['DG1.1.1'] = msg['DG1']['DG1.1']['DG1.1.1'][count].toString()
    count++;
}

Also - if anyone wants this channel for use as an example e-mail me offline and I'll send it to you.

Hurray! Hurray!

Need sample channel

Please send me sample channel to process repeating segments in Mirth.

[RPHaa]

Does anyone have a sample channel that shows this looping process?

Thanks
