How can I remove duplicate information from NTE Segments.

Question

I have duplicate NTE segments and would like to remove the second instance of it.

Example:

 

NTE|19||

NTE|20||Electronically Signed 8/25/2015 9:54 AM

NTE|21||Doctor A MD, Pathologist

NTE|22||

NTE|23||Electronically Signed 8/25/2015 9:54 AM

NTE|24||Doctor B MD, Pathologist

NTE|25||

…

Answer 1

The following code will check that we have 2 Electronically Signed Segments and remove the last group.

//See if we have multiple 'Electronically Signed' in NTE

var split = StringUtils.splitByWholeSeparator(message.getNode('/'), 'Electronically Signed');

if (split.length > 2) {

 

   //Get Count of the NTE segments

   var nteCount = message.getCount('NTE');

 

   //FOR loop reversed to process last NTE first

   for (var i=nteCount ; i > 0 ; i--) {

      //If statement to check for second 'Electronically Signed' NTE segments

      if (StringUtils.containsIgnoreCase(message.getNode('NTE-3', i), 'Electronically Signed')) {

         //Remove 3 NTE segments when second 'Electronically Signed' segment is found.

         for (var j = 0; j < 3; j++) {

            message.removeFirstNode('NTE[' + i + ']');

         }

         //Break so we only remove the last one and do not continue to process the rest of the NTE's

         break;

      }

   }

}

Here is the resulting segments

NTE|19||

NTE|20||Electronically Signed 8/25/2015 9:54 AM

NTE|21||Doctor A MD, Pathologist

NTE|22||

 

Answer 2

Another way would be to store the NTE-3 value in a parameter map and then remove the three lines following the duplicate "Electronically Signed" text.

 

 

// remove every NTE segment

message.removeAllNodes('NTE');

 

// store the original NTE segs as an array

var nteSegs = source.getAllNodes("NTE");

var nteMap  = qie.newParameterMap();

 

// cycle each NTE segment and only add not duplicate

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

   qie.debug(nteSegs[i]);

   var nteSeg = qie.parseHL7String(nteSegs[i]);

   var nte3   = nteSeg.getNode('NTE-3');

   if (nte3.length() > 0 && nte3 + '' !== '_~') {

      //need to check in the nteSegs array if this current NTE segment exists.

      if (nteMap.get(nte3) === null) {

         message.addChild('/', 'NTE', nteSeg);

         nteMap.put(nte3, true);

      } else if (StringUtils.contains(nte3, 'Electronically Signed')) {

         // So this nte3 was already found once so now remove the next three lines by skipping them.

         i = i + 2;

      }

   } else {

      //go ahead and add blank lines or lines that equal '~'

      message.addChild('/', 'NTE', nteSeg);

   }

}
