Health Level-7 or HL7 refers to a set of international standards for the transfer of clinical and administrative data between software applications used by various healthcare providers
I am looking for an appropriate solution to generate HL7 test messages to test my production. IRIS for Health already contains many HL7 specific functions like the schema structures. Furthermore one can use transformations to build custom messages.
What I am interested in is if anyone has already created a tool or script that can be used to create any HL7 messages that meet the minimum requirements and populate all the required fields with test values. I would then like to send these test messages via TCP to a business service.
In this article we are going to see how we can use the WhatsApp instant messaging service from InterSystems IRIS to send messages to different recipients. To do this we must create and configure an account in Meta and configure a Business Operation to send the messages we want.
Let's look at each of these steps in more detail.
Setting up an account on Meta
This is possibly the most complicated point of the entire configuration, since we will have to configure a series of accounts until we can have the messaging functionality.
First of all, thanks for your help, and time, reading this questions, and answering to this doubt.
We have the following use case: to convert a HL7 ER7 ORU_R01 v2.5 message, to a Ens.Request Message which represent it with a custom data structure (each segment is a group of Properties).
To be more precise, the target Ens.Request Message's structure looks like:
Hello, I tried to convert HL7 message to JSON in a business process and I got errors. Has anybody converted HL7 to JSON? Are certain characters not allowed in JSON?
I just tried to set a property to quote request.RAWContent and quote. I will try to put example in GitHub and share here later.
Written in reply to community post for can Python create HL7 Message dynamically.
Pre-requisites and setup
Use an integration enabled namespace. Note: USER namespace is not enabled for interoperability by default. If following suggest create a new interoperatibility namespace to explore functionality.
# Switch to ZN "[Interoperability Namespace Name]"
# Launch interactive Python shell: Do $SYSTEM.Python.Shell()

In part I of this article, we have already learned more about HL7, its messages, structure, segments, and fields. In this part II, we will show you how to transform proprietary/custom data into HL7 using IRIS for Health. For our sample, we used the data generated by the SYNTHEA bulk data generation project (https://synthea.mitre.org/downloads). So, we will show you how to convert 1000 patients from a CSV file to HL7 v2, using the Interoperability features of IRIS for Health.
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.

I have a problem attempting to store a base 64 encode stream into the OBX:5 field of a HL7 message, by using the StoreFieldStreamBase64 method.
I'm using a transformer to input the contents of a pdf within a stream container (Ens.StreamContainer). The output is a HL7 message (EnsLib.HL7.Message 2.5:ORU_R01).
The transformer is being used in a business process.
This is the code used in the transformer to encode the stream to base 64:
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?
This article aims to explore how the FHIR-PEX system operates and was developed, leveraging the capabilities of InterSystems IRIS.
Streamlining the identification and processing of medical examinations in clinical diagnostic centers, our system aims to enhance the efficiency and accuracy of healthcare workflows. By integrating FHIR standards with InterSystems IRIS database Java-PEX, the system help healthcare professionals with validation and routing capabilities, ultimately contributing to improved decision-making and patient care.

We've been asked to develop a HL7 interface, but the end system has very different needs than any we've ever interfaced with before. We need assistance to determine if these needs are things HealthShare can support that we're just not aware of, or whether we'll need to develop some custom code to accomplish this.
I have a production with a HLv2 HTTP Listener.
For demo purposes, I need to send HL7 messages directly from a browser. Here is an example (React/typescript):
Within a DTL is it possible to access and update the Message Header properties of an EnsLib.HL7.Message?
Currently we have multiple EMR Services for each environment sending to 1 Business Process to Normalize the data, then it is sent to another Business Process to route the data.
First of all we would like to thank you for your time reading, thinking and aswering this question.
We have been developing a Transformation to convert a source ORU_R01 to a target ORU_R01. For each OBX segment we need to check an if, and then, if it is true we just need to put this OBX and continue to the next iteration, otherwise, if it is false, we need to put (copy) the ORC + OBR + TQ1 before this OBX, and then put this OBX, and after that, the SPM.
Watch this video to learn about a new tool – HL7 v2 Data Profiling Tool – to help speed up onboarding of HL7 v2 data feeds by validating messages against standard schemas, custom schemas, and SDA:

A set of 14 interactive practice questions are now available for the InterSystems HL7® Interface Specialist Certification exam. These questions have all been developed by our subject matter experts. Feedback for these questions include documentation resources and online learning content.
It could be great if some of you have had experience in hl7 v2 messages. The question is about FHIR to hl7 v2.5 conversion. I have to translate a binary resource, encoded in base64 into an orl_o22 message. Do you have advices? Which field could be used for that datatype? I have found some implementation using nte segment but it is limited in characters.
I have been successfully able to transform hand-written medical test results documents to HL7 ORU_R01 v2.x, then to SDA, which will be trasformed to FHIR or C-CDA.
However, I have a category of documents which contains reference range in multiple date formats, which are measured for each gestation period. For example, below is one of the documents.
We recently uploaded to OpenExchange a small application that I developed a while ago (and that @Jose-Tomas Salvador improved and refined) that I often use when I need to generate large volumes of HL7 messaging.
