#HL7

We are using a DTL transformation to take HL7 and transform into custom XML. But the nodes in the resulting XML are appearing out of sequence - and therefore failing validation against the schema.

The XSD schema for the XML looks fine when imported into Ensemble: root node in the XSD looks like this:

And shows in Ensemble like this:

The transformation looks like this, and we can see the text from the trace elements at lines 5, 12 and 19 appear in the correct order in the event log:

HOWEVER, the resulting XML has the <allergies> nodes before the <patientNotes> nodes.

We are using a DTL transformation to take HL7 and transform into custom XML (XML is a virtual document, held in an EnsLib.EDI.XML.Document object). The schema specifying the format of the XML says one element should occur no more than 24 times (maxOccurs="24" in the XSD schema). However, the transformation to produce one such element always produces 24 elements, all but the last one blank, when tested stand-alone. And when the sub-transform producing one element is incorporated into the full transformation to produce the whole XML object, it produces the wrong output.

Hello,

I hope this is a simple ask..

basically I need to create local files daily at a certain time for example 11:30pm.

1. file name needs to be like  xxx__20250113.txt , the date part should be next day's timestamp with format YYYYMMDD, so I will write about 17 files like that with different names.

2. write a dummy hard coded word for example “Dummy Word” in the file.  the file eventually will be used by other operations to add hl7 message on top of this  in it with the live interface message. 

3. this needs to be done every night at 11:45pm

So how am I going to implement this?

Hello,

is it possible to kill/suppress hl7 message in the DTL (data transformation).

in cloverleaf, it is common practice to check the value in message, for example pv1:7.9. if the value is certain word(assigning authority) then send the message over to destination, if it is not, kill the message

how would this be done in InterSystems ? does that need to be done in the rule instead? or can it be done in the data transformation? if it can be done in data transformation, how can it be done? 

Thanks

I've just stumbled across this post. I am an aspiring developer and one of my first few projects is a HL7 v2 message generator. It takes in a message template and then you can edit and create bulk messages from it. 

Simply choose which segment to edit, specify the field position and then you can add a CSV of values. test, test2 and so on. You can choose to download the messages or display them in your browser. It also provides a JSON file showing you which new values are grouped. Not sure of all the use cases but I built it for a bit of fun over a weekend!

Hi everyone,

I'm looking for a tool that can be used as a base to create an interface that allows a non-technical user to easily forward messages. 

The idea is that the user can find an already sent HL7 message and forward it by modifying specific fields of the message without needing any technical knowledge.

An example would be something similar to the Ensemble search engine, but with a less technical and much more intuitive approach and that only allows changing 1 or 2 fields. 

Is there a solution in the community or something that I can adapt for this purpose?

Very similar question posed here: https://community.intersystems.com/node/467496, but I am missing a piece of this:

How do I correctly call a EnsLib.HL7.MsgRouter.RoutingEngine class from the BPL?I can successfully call the BPL from the EnsLib.HL7.Service.TCPService, and I have the BPL created to delay then call the rule. And I set the context and the result location.

This rule is really basic just sending the HL7 content to a EnsLib.HL7.Operation.

We are building a data transformation from HL7 to custom XML. We've got an XML schema, and are using virtual documents (EnsLib.EDI.XML.Document).

We can:

• build our transform as a single transform
• build our transform using subtransforms where the source data for the subtransform is all in a single HL7 segment and all the output data goes into a single (complex) element of the XML, so the input type on the subtransform is the segment from the HL7 schema and the output type on the subtransform is the relevant element picked out of the XML schema:
  
• but we can't (so far!

Hello, 

We noticed from the integrity logs that some of the namespaces in our integration engine are using large amount of space ( ~380GB ) for the global ^EnsHL7.Segment. 

We have culling implemented for large globals like MessageHeader and MessageBody.

Is it a standard process to implement culling for ^EnsHL7.Segment global and any idea about what will be the impact of adding culling to this global?

Like many others probably find themselves, we were stuck doing live data mapping in our Interface Engine that we really didn't want to do, but had no good alternative choice. We want to only keep mappings for as long as possibly needed and then purge expired rows based upon a TTL value. We actually had 4 use cases for it ourselves before we built this. Use cases:

Dear All,

I have been sent an HL7 message as a file with the MSH segment as follows....

MSH|^~\&|SendingApp|pms3medd|HealthLink|cribrumt|20241121050000|PKI|ORU^R01|01_ASCIItest_2|P|2.3.1||||||UNICODE

I try picking up the file with a "EnsLib.HL7.Service.FileService" business service using a  EnsLib.File.InboundAdapter adaptor.  The Character set is set to "Native" and the Default Char Encoding to latin 1.

I am seeing the following error:

ERROR <Ens>ErrGeneral: Incorrect Character Encoding/Translation Table used for file.(Native/RAW)
+
ERROR <Ens>ErrException: <TRANSLATE>ParseIOStream+71 ^EnsLib.

Has anybody encountered this before?

I did a very usual hl7 adt transformation DTL, but it is with a customized schema, like ADT_ALL, it is a structure that tries to cover all the ADT schema scenario so we can use 1 type for all ADT messages.

the DTL tests fine in DTL test, with all the segment transformed correctly, but once I put it to test, to send message through source and the message after transformation can only go to MSH, EVN, but won't transform other segment like PID etc.

Production Configuration

This demo has an interoperability production with 16 items. 

Production Configuration HL7 + Kafka Producer

The first part of this demonstration consists of sending an HL7 SIU file which will be transmitted to the 2 other HL7 flows (HTTP and TCP), and transformed and transmitted to the Kafka server. HTTP and TCP flows will transform HL7 messages in the same way before sending them to Kafka as well.

Hi Team,

I am converting xml message into HL7 message but the input XML message contains pdf which is converting into base 64 and getting mapped to OBX:5.5 in HL7 message and sending it to downstream 

In Downstream service i am using normal HL7 TCP class EnsLib.HL7.Service.TCPService but the message looks like below i am not sure why stream is taking as another segment in HL7 message,

Any thoughts on this?

Thanks,

Smythee

Throughout the forum, I find examples of using the method getSegmentByIndex to get the segment as I loop through the HL7 message segments.

Today I spent way too long trying to figure out why I could not modify the segment with this same method. I reached out to my more experienced team and I showed where I got the base code from what I was doing, but I myself could not find the documentation of the method.

After some time, we stumbled upon the GetMutableSegmentAt and GetSegmentAt methods and plugged the mutable method in its place and what do you know, it worked!

As the title suggests, I would like to programmatically export each HL7 schema category as XML, either as a stream object or to a file. How would I go about doing this?

I was working on a DTL but kept getting ERROR #5002... MAXSTRING errors. The problem was that most of the DTL GUI action steps only support the string data type when working with the segments. A %String has a limit of 3,641,144 characters and my OBX5.1 was 5,242,952 characters long as the example provided. Of course PACS admin stated ultra high quality up to and including 4K resolution files were needed, so we could not get the vendor to compress or reformat these files to compressed jpg or something similar.

Initially this vendor sends a 2.3 ORU^R01 and our EHR (Epic) is expecting a

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

Hi everyone,

I'm struggling with the extraction of information from the following XML:

Hi

I was wondering whether there are any best practices or guidance around converting a HL7 message in to XML stream which will then be delivered to an end-point.  Any help would be much appreciated.

Kind Regards,

Salma

I am still trying to understand and come up with a use case to use FHIR as an enhancement to our existing HL7 messages. Does anyone have an example of taking a FHIR response and transforming it into a SDA?

How does the workflow go? Does it go through 1 BP? 

Thanks

Scott

I have a theory that I could use an HL7 Data Transformer in a rule without specifying a specific DocType. I want to use the same DTL for a variety of different DocTypes. Here is my very simplistic DTL so far:

Class OrdRes.TestTransform Extends Ens.DataTransformDTL [ DependsOn = EnsLib.HL7.Message ]
{
    Parameter IGNOREMISSINGSOURCE = 1;
    Parameter REPORTERRORS = 1;
    Parameter TREATEMPTYREPEATINGFIELDASNULL = 0;
    XData DTL [ XMLNamespace = "http://www.intersystems.com/dtl" ]
    {
        <transform sourceClass='EnsLib.HL7.Message' targetClass='EnsLib.HL7.

We need to generate a PDF file from an HL7 message as it passes through an Ensemble production. Looking for examples, tutorials, documentation aligned to our scenario.
We are currently using Ensemble (so can't use InterSystems Reports at the moment). Thinking Zen reports...
We can get from HL7 to XML OK, following Introduction to InterSystems Health Connect - YouTube (see c.1:11:00-1:13:00)

We can follow the Zen tutorials to a point - but they mostly get the data being presented in the report from SQL queries rather than from an in-bound XML

I am trying to create a HS.FHIR.DTL.vR4.Model.Resource.Encounter message based on a conversion of HS.FHIRServer.Interop.Response QuickStream to a JSON %Dynamic Object. 

When I try to send the HS.FHIR.DTL.vR4.Model.Resource.Encounter onto the Router

1. it is not showing up as a Defined Message Class to Route the message back to the SourceConfigName of the Request message that initialized the FHIR query
2. I keep getting "ERROR <Ens>ErrBPTerminated: Terminating BP EPIC.FHIR.Process # due to error: ERROR #5002: ObjectScript error: <SUBSCRIPT>%SaveData+29 ^Ens.MessageHeader.1 ^Ens.

I have a requirement where in I had to read a HL7 message string ( which is a String )
from a SQL TBL to my Business Service.
and I need to convert that string to EnsLib.HL7.Message format and traverse through the PID segment.

I need  some inputs please.

Hi all.

Recently, I have noticed Scott Roth's mission to resolve issues with Orphaned messages with a lot of focus on prevention, and I envy that level of dedication.

Not wanting to be left out, this has sparked an interest in checking my environments for orphaned messages. Amongst a few different posts on the subject, I came across this post from Suriya Murugan in 2016 that included an interesting class in a Github Gist that seems to be built to do a deep dive into the identification and cleanup of Orphaned Messages.

Does the assign action not work? Why doesn't MSH:7 get updated to the current DT?

Hi

I want to check patient class in multiple rules, since the message structure is different to reach out to patient class value, i created a method to get the patient class and put it in a variable. This variable i can use in multiple rules. But somehow function is not able to read the HL7 message. Any tips.

In rules i have this assign line.

Function code looks like this, but in the msg pHL7 dont contain any. I tried getPatientClass(HL7) as well as getPatientClass(HL7.Source)

ClassMethod getPatientClass(pHL7 As EnsLib.HL7.Message) As %String
{ try{
SET msgType = pHL7.
