HL7

Hi

I've got a Service that get ACK Messages originated by another system. 

I want to get the details of a Message when the ACK is CE (Failed Message).

I don't know whether this is the best approach but, at the moment, I have a DTL and I would like to search the Cache Database for a Message with the Control ID on the ACK in the MSA segment.

Any help with this would be great.

Tks.

Hello,

Are there any utilities/api in HealthConnect 2016.2.1 that will allow conversion of XML virtual document to Json format? We were thinking to convert HL7 ADT message to XML via Ensemble DTL and then send it to another BP to convert to Json format for transmission via Web Services. To my understanding there isn't anyway to represent Json as a virtual object so it can be use for direct mapping of HL7 2.x message to Json via Ensemble DTL.

Thanks

Ensemble 2015.  Working on an a way to send NACK'd HL7 messages to a flat file for external review/troubleshooting. (Similar to the way BadMessageHandler deals with validation errors.)

I think I have the Alert piece down, but need assistance with the exact syntax to do an SQL query in the DTL (or a custom function) to pull the HL7 message Raw Content into the Alert, based on the SessionID.

(Also, anything special to write alerts to the File Operation?)

Thanks,  Brian

I have created a class that extends file operation, but can't find the object that has the value for the file path. Is that object in pRequest or is there an another object I should be used to see that value?

Is there a way to use a HL7 field value as part of the File Naming in the Business Operation FileOperation class.  I know we can do this in a custom class, but I was wondering if it could be done the default FileOperation class?

Example:

MSH-4 contains the value 12345

We would like to name the file 12345_YYYYMMDDHHMMSS.HL7

MSH.4 value here_%Y%m%d%H%M%S.HL7

It may not be possible, but I just want to see if anyone has any information

Thanks,

DTL Transformations and GetValueAt/SetValueAt calls on HL7 messages will truncate any fields longer than 32K.  To avoid this, the methods GetFieldStreamRaw and StoreFieldStreamRaw must be used when dealing with fields that might be larger than 32K.  OBX:5 is a frequent example.  These methods have some subtleties and must be used carefully.

This can't be done by simply dragging from left to right in a DTL.  It must be done with a code action.  Also, the StoreFieldStreamRaw call must be the last edit made to the segment because the segment becomes immutable after that.

StoreFieldStreamRaw takes 3 arguments: The stream to put in the field, the VDoc path of the field in which to store the stream, and a pRemainder argument.  If the pRemainder argument isn't specified, then all fields after the field being stored are blown away.  If pRemainder is specified, then all fields after the one being stored are replaced with what's in pRemainder

I have a case where I have a SIU message that has multiple RGSgrp's. I am writting the first RGSgrp fine, but when it comes to the additional RGSgrp's, I want the ability to look at the Target SIU message and see if the value exists.  If the AIG.3 already exists in the Target message I want to stop the looping and not write out the data.

Can anyone suggest a way to do this? Is there a way in a DTL to build a list or temp lookup table to see if something exists?

Thanks

Hi Everyone,

Link to webinar recording: https://learning.intersystems.com/course/view.php?id=623

Thank you for your interest in this webinar!

Please submit questions about the content of the webinar as comments below this article.

The webinar covers two topics: monitoring message activity and volume and monitoring disk space. I summarize and motivate the topics in the following two sections. The information in this webinar and post applies to the Ensemble, Health Connect, and HealthShare products. For simplicity, I am only going to refer to Ensemble in this post.

1) Monitoring Message Activity and Volume:

Folks

1) What's the correct way to check for an existence of a segment?  So far I have been doing this by checking to see if a required field is non-null, and this seems to work but is a bit clumsy. In this case, it’s an X12 message being checked in an IF action in BPL:

              request.GetValueAt("NTE(1):Description")'=""

Or in a DTL, to see if a Z segment exists:

              source.{ZEF:Counter}=1

2) I have a case where I need to change from an external date format (YYYYMMDD) to internal (+$H) for a DTL to create a new object (and then persist it later). I am using:  +..ConvertDateTime(source.{G62:Date},"%Y%m%d","%q(3)") Is there a cleaner way using built in utils or without writing a custom function

Hi all,

I was wondering if InterSystems offers any message profiling capabilities. What I mean by "message profiling" is essentially stats or metrics gathered from a collection of data submissions of a particular type. For instance, average number of segments  <XYZ> in a specific HL7 V2 message type. Or the number of sections found in a HL7 V3 CDA documents.

Curious if there is anything like this provided "out-of-box".

Thanks!

noob here..(moving from JCAPS to Ensemble)

We are wondering where is the best place to tie the schema category for an incoming HL7 message? Should we do this within the service (via the message schema category setting) or receive everything and validate in the process (DTL) level?

We want to capture everything that will be sent to that HL7 listener service and then decide what to do with bad messages at the process layer.

Does anyone have any recommendation regarding this? Appreciate your input and decision thought process.

Thank You,

Hi

I need to process a very large Batch file which contains HL7 charges which we pull using FTP. I need to loop through the file and do some checks and then split the large Batch file in to individual messages. These individual messages then gets process through a different module to create a output batch of different format

Hi all,

We have a big problem with spanish accent and special characters using Data Transformation (HL7 Messages).

We have some DT to transform HL7 messages to other type (OUL^R22 To OML^O21) so it copys the PID segment to the new one, but if in the PatienName field has any special character, the transformation stops and it not continues with the transformation.

This is the message
 

MSH|^~\&|B11111111|000000000C|LAB|TSFLAB|20170117163714||OUL^R22|ID1||2.5||||||UTF-8 
PID|1|1234567890134567890|00000000R||MUÑOZ LÓPEZ^JUAN^||19900101000000||||&||
OBR|1|23145687456894561321|23141211||||||
ORC|RS||4385025|||||||||
 

The transformation changes the "Ñ" and the "Ó" to "?", however if I'm using a personal structure based on HL7 2.5, the transformation doesn't work and the test page gets stuck

For testing purposes, I would like to create an EnsLib.HL7.Message from either a %String or a file on disk and pass it into a function in a unit test (outside of an Ensemble context). EnsLib.HL7.Parser appears to do the necessary parsing, but it also sends the message via Ensemble service rather than returning it as a value. Is there a way to leverage the parsing outside of a Ensemble service? Alternatively, is there another way to create an EnsLib.HL7.Message?
