What is the best way to create an HL7 message from JSON input file?

We have JSON file available with data required for building the HL7 message . I am trying to use a standard file/FTP Business service to pick up the file and convert the input %FileCharacterStream into a dynamic Object and use the stand JSON features to read /process the data and build the HL7 message.

Is there any other better way to do this? or any standard built-in functionality available in HealthShare?

Thanks you for your help

Awhile back the Developer community helped me with a situation I was having... How to loop through a Repeating Segment and Single Filed, example OBX().5, within a Business Process Rule and compare it against a Data Lookup table.

Well now I need to take it a step further. I need a way to loop through OBR() segment, and loop through OBR().4() and the subfield 4.1 and compare it to a Data Lookup table.

So I thought I could copy my existing function code and add another level to it, but its not returning what I would expect.

Good Afternoon My InterSystems IRIS Peers,

I have the following issue that I need help with, I tried all possibilities that I know of, therefore I am reaching out to the community for some insight.

I have a SFTP service that pulling 2.5.1 DFT HL7 messages from our SFTP file server. The issue is that IRIS is transforming patients names and addresses that contain special chars UTF-8 to ANSI.

Examples:

è = è
é = é
í = í- .......etc

Curious if anyone has modified the HL7 TCP/IP Service and adapter class to receive an HL7 message, ACK it, and just dump it straight to a file? I don't want the messages in the engine at all - just receive and dump. Has anyone done this before and have code you're willing to share?

Thank you very much in advance!

Hi there,

I'm working on a project where I retrieve RawHL7 message(ORU R01 2.3.1) content from a database in a BPL. I've created a context object of type Enslib.HL7.Message, and I need to populate it with the contents from the RawHL7 message so that I can use this context object as source for my DTL transformation.

Does anyone have suggestions on the best approach to achieve this? I'm looking for guidance on how to efficiently transfer the data from the RawHL7 message to the context object.

Thanks in advance for your help!

What is iris-hl7?

An App that converts HL7 messages to JSON objects. About a year ago I started a GitHub repo for collecting stuff related to HL7. Recently my team added an HL7 interface to our Interoperability Production and we were asked to persist HL7 messages. We created a Kafka topic to receive HL7 messages. We use Kafka Bridges to send messages to Kafka topics. Kafka messages are sent to the Kafka Bridge in JSON format.

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

Custom Schema

Hi-

Please excuse my rather limited knowledge of HL7.

In Ensemble, I have a HL7 message that contains several Z segments. I have created a custom schema to represent the new Z segments along with the new DocType Structure and Message Structure

How does Ensemble/Health Connect know which custom schema to use? I believe it has to be indicated in the MSH segment somewhere, but not sure where exactly that would be. Is the version simply updated with the new schema name or is there some other field?

TIA

Ken

So I have an interesting problem. I am going to be using a process and rule to determine if an HL7 message qualifies to be sent out, then using a record map to write certain aspects of that HL7 message to disk (with an HL7 to record map DTL). This is simple enough but the recipient of this file is requiring a single record map entry per DG1 segment in the HL7 message.

For instance if said HL7 message for PATIENT^TEST has 3 DG1 segments, I would need to write three lines (or records) like so:

123^^^^MR|TEST|PATIENT|DG1(1) TEXT|DG1(1) CODE|DG1(1) DATE

modifying patient address in DTL

Hi

Newbie question. Could you please help me implement the following using DTL only - no programming.

We have a problem where our system sends longer addresses e.g. block of flats in an unexpected format

e.g. address below:

I am working on tweaking our current patient load process. The roster input is in text pipe delimited format, parsed out and transforms it to a standard HS.Message.PatientSearchRequest, and send to business process for patient matching. Result is transformed into a standard ADT HL7 message using EnsLib.HL.Message class. I would like to know if there is another class I can use that will transform my output to a text flat file pipe delimited instead of HL7 format? any advice on how to do this is greatly appreciated.

Thanks!

Hey Developers,

In the second part, you will learn how to build a FHIR Application with OAuth 2.0 and OKTA:

Greetings.

I have a scenario in ENSEMBLE, where a business process router A is dependent on another business process router B. If B shuts down for some reason, A has to be disabled as well.

Do i need to write a custom process for B and call the call back method onShutdown or something?

Any suggestions would be appreciated.

Thanks,

Jimmy Christian.

I'm doing some Schema changes. I used our existing standard schema as a base, which was already based on 2.3. So let's call our existing one Custom.MHC.Schema (based on 2.3). I created Custom.MHC.Schema.Advanced (based on Custom.MHC.Schema) and copied down one of the code tables then made a change to it.

When I ran a message through, the code table change didn't show up. I noticed in the message viewer that the DocType is still Custom.MHC.Schema:ADT_A01 but the DocType Category is Custom.MHC.Schema.Advanced.

So this may sound trivial, but I'm seeing conflicting information on this topic and hoping to get clarification.

According to Enslib.HL7.Message class definition, the maxlength of RawContent is 10,000 characters. So when using encoding like UTF-8, that is 10KB. When using Unicode, that should then be 20KB.

But then also coming across some forums and documents where 32KB is maximum size before HL7 fields are truncated.

What is the sure way to determine and modify an interface's maximum supported message size?

Hello.

I have a delimited flat file that I need to read and then generate an HL7 A08 message from the fields in the file. I used the Management Portal's Record Mapper to generate the Map.Record class, then used drag & drop to map fields in the delimited flat-file to an A08 message.

But when I try testing this in the test tool, I'm getting an ERROR #6254: Tag expected . XML input. ... is not in proper format as child of Record (ending at line 2 character 11).

Hello,

We are wondering how could we iterate over a segments list,

The use case is that we are sending from Process X to process Y a message, only if at the OBR4 CE1 there is a certain code. We were getting this field as follows:

set context.studyReason = request.GetValueAt("ORCgrp(1).OBRuniongrp.OBRunion.OBR:UniversalServiceIdentifier.Identifier")

How could we iterate over the following message and get both OBR4 CE1 (1 and 2):

suppressing a patient identifier

Hi all

Another newbie question.

A small percentage of our patients have an extra hospital number which was imported from the previous PAS but is no longer in use. We only need to send MRN and NHS number and would like to suppress CMRN. Could you please advise me how to do it in DTL?

We are seeing ERROR #5002: Cache error: <MAXSTRING>zSaveData+14 ^EnsLib.HL7.Segment.1 come up on a Routing rule when we are trying to Encoded PDF's through a DTL. In the DTL we are copying source to target. Is there a limitation on trying to copy source to target?

At the bottom of the DTL you are see that we commented out converting the Encoded PDF to a Stream, is it recommended that we always use %Stream anytime we are dealing with PDF's?

Thanks
