Search For Missing OBX Children in an OBR

Question

Some messages have multiple OBR segments with missing OBX children. They have an NTE, but no OBX. I need to search the message for all OBR that don't have an OBX and add it. I also need to take any NTE segments in the OBR and put NTE-3 in OBX-5. The OBX segment can go at the end of the OBR after the NTE if it exists.

Thanks for the answer. The key important thing I missed was to parse the obrGroup as an HL7.

Answer 1

Here is a script to add OBX segments if they do not exist in the OBR group:

//Get all OBR groups

var obrGroups = message.getAllNodes('OBR[group=!OBR]');

 

//Loop through each group

for (var i = 0; i < obrGroups.length; i++) {

   //Parse the string as hl7 to allow lookup.

   var obrGroup = qie.parseHL7String(obrGroups[i]);

   

   //Check if an OBX segment exists.

   if (!obrGroup.checkNodeExists('OBX')) {

      //Get the NTE-3 node to use in the OBX-3

      var obx5 = obrGroup.getNode('NTE-3');

      //Add the OBX segment after the NTE segement.

      message.addChildAfter('NTE[@3=' + obx5 + ']', 'OBX', 'OBX|1||||' + obx5);

   }

}
