#HL7

I've been preparing to take the InterSystems HL7 Interface Specialist certificate and on the page that explains the cert it lists one in-person class and one online course. I've been through the suggested online course but when I read through the practice questions there are a lot of things that aren't covered or mentioned in that course. Naturally I could go digging through the documentation but there is no specific guidance about what things to study.
I was just wondering if there is a better organized collection of study materials for cert prep.

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.

The application is developed in NodeJS and works by generating patient and doctor data from seed files that you can modify to your liking to personalize the generated patients. The application will use the generated patients to prepare different types of HL7 messages. At the moment the application can generate the following types of messages.

What are the advantages/disadvantages of using the Person resource with a link to the Patient and Practitioner resources, rather than using the Patient and Practitioner resources directly without using the Person resources?

HL7 schemas do not appear in the browser in VSCode. How to access/see them?

How to include them in GIT from VSCode?

If you're viewing a HL7 message in the front end, with a schema correctly applied, you can mouse over a segment or a field and see the schema path, e.g:

Mousing over PV1 in the above message shows the schema path is "PIDgrp(1).PV1".

I'm writing a utility function which you pass an EnsLib.HL7.Message into. I'd like to loop through each segment and take action dependant on that schema path. How can I reference or determine that schema path in code?

Any help would be much appreciated!

Hi Developers,

Does the GetValueAt method of an EnsLib.HL7.message object change the contents of the HL7 message?

We want to do two things, given an incoming HL7 message, in our production:

• transform the HL7 to XML, where the class TNHS.Utils.HL7toXML provides the same methods as, for example, EnsLib.HL7.Util.FormatSimpleXMLv2:
  

  set sc = message.OutputToLibraryStream(xmlstream,"","","TNHS.Utils.HL7toXML")

  
   

• extract a value from a particular field in the message: 
  

  Set ReportId = message.GetValueAt("PIDgrpgrp(1).ORCgrp(1).ORC:3.

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!

Hello Everyone,

How do I provide my input? We will provide a list of job tasks. You will rate them on their importance as well as other factors.

How much effort is involved? It takes about 15-20 minutes to fill out the survey.

How can I access the survey?

Hi Developers!

Hi Community,

Watch this video to learn how to create new business services and business operations in an HL7 V2 production in InterSystems products:

⏯ Creating HL7 V2 Production Components

Sometimes we need to convert FHIR message to HL7 V2, e.g. to register a patient to the PACS system.
In this article, I will explain the steps to achieve the desired by using IRIS FHIR Server production.

Below are the steps we need to follow:

1. Make sure FHIRServer production is started.
2. Register Business Service with FHIRServer endpoint.
3. Define Business Processes to convert FHIR message to SDA and then Convert SDA to HL7 v2.
4. Post JSON resource to FHIRServer endpoint and get HL7 V2 response.

Let's review the steps in detail.
 

Step 1. Make sure FHIRServer production is started

Open the production page and make sure Production is started. In the next step, we need to make sure business service HS.FHIRServer.Interop.Service is registered with FHIRServer

Hi

Where is hl7 data and how to access after data coming through TCP Service?

The data is automatically saved? In database or queue or cache? How to access from ObjectScript? Any documented example?

Thank you!

William

Do you ever spend an age entering criteria in the message viewer page, trying to find a message just to realise you're in the wrong instance of IRIS? 

Or get lost in a sea of message tabs struggling to spot that Visual Trace page your were JUST looking at?

Well, have you tried the IRIS WHIZ browser extension and its suite of tools designed to help you avoid such unpleasantness?

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.

I contemplated how to transform HL7 messages to JSON. HL7 message Raw Content property provides the HL7 message in String format.

Hello,

First of all thanks for your help reading and answering this question, and thanks for your time.

We have been investigating how to handle the following need:

Our client which has the system which reveices our ESB's responses needs a SOAP response as follows, where all the ACK is inside a top XML tag called <ACK>:

<?xml version="1.0" encoding="UTF-8"?><ACK xmlns="urn:hl7-org:v2xml">
    <MSH>
        <MSH.1>|</MSH.1>
        <MSH.2>^~\&amp;</MSH.2>
        <MSH.3>
            <HD.1>sistemaExterno</HD.1>
        </MSH.3>
        <MSH.4>
            <HD.1>scs</HD.1>
            <HD.

I am using Intersystems Iris Community Edition. I have created a Rest Api to post HL7 message directly through postman. It is working fine, But I want to create the business service to read the HL7 message from Rest- Api. I tried to create this, but I am not understanding how to do that. Can anybody help me?

Job Description

I am trying to pull out something similar to an HL7 date/time stamp in a custom zen page , in a javascript code section.

var d = new Date();

(Fri Jan 12 2024 16:58:30 GMT-0500 (Eastern Standard Time)

but,
var year = d.getFullYear();

d.<formatcmd>  doesn't seem to work.  (d.getmonth, etc.)

Is there and date formatting I can use inside a javascript routine?

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.

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. 

Since the SourceConfigName changes with every send to a Business Process, I am looking for a way to maintain the SourceConfigName of the SessionID so I know how to direct the message.

I would like to strip the , at the end of a string. I'm able to find the start of the string using ..StartsWith(String,",") but not able to strip the "," at the end of a string.

I've tried:

Str="Addr1,Addr2,"

Piece(Str,"",1,Length(Str)-1)

Piece(Str,"",1,Length(Str)-2)

Extract(Str, Length(Str)-1)

Extract(Str, Length(Str))

But nothing works as expected.

Hello community,

I am trying to see the complete HL7 message for the class  EnsLib.HL7.Message.

But it is showing the truncated version only.

I also tried to convert to stream

d msg.OutputToLibraryStream(.streammsg)
s newmsg=##class(EnsLib.HL7.Message).ImportFromLibraryStream(streammsg)

While (streammsg.AtEnd = 0) {
     Set len = 1000
        Set tPrintMessage=newstream.Read(.len)
     Write tPrintMessage
}

But when i print it, its not showing complete message.

Any idea or suggestions?

Thank you in advance.

Jimmy Christian.
 

Does anyone have an effective tool for anonymizing/deidentifying CCDAs for testing purposes?

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.

Hi all

I'm having trouble defining the mapping needed to take the very large base64 string in OBX:5.5, and map it to an XML virtual document property that supports Stream.GlobalCharacter. I know from within the DTL you have to use custom code to manage the segment due to its size. 

do target.StoreFieldStreamRaw(.stream,"LetterAttachment(1).Base64EncodedFile(1)", .rem)
 set tObx14Value = $piece(rem,"|",10)
 set convertedDate = ##class(Phu.Shared.Util.DateTime).ConvertHl7DateTimeToXmlDateTime(tObx14Value)
 do target.SetValueAt(convertedDate,"DocumentDetails(1).AuthoredDate(1)")
 do target.
