#HL7

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:

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)

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

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)

Hello,

First of all thanks for your help, and thank you for your time.

We have the following task:

To generate by hand the Ens.Request with the properties and inner Data Schemes which represent this XML, in HealthShare, by hand; the XML is this one:

In a HL7 Business Rule, I want to create a custom function that works on an HL7 message object (ENSLIB.HL7.Message).  I extended the Ens.Rule.FunctionSet class, and have a class method that accept a ENSLIB.HL7.Message obj -

ClassMethod myfunction(msg As EnsLib.HL7.Message) As %Boolean,  so I can call   myfunction(HL7)  in the rule's condition

The problem is, it seems that I can only use absolute property paths such as msg.GetValueAt("1:9.2") but not a path containing HL7 segment name,  for example as in msg.GetValueAt("MSH:9.2").  This is a huge limitation.

Hi

Is there a way to generate an MD5 checksum of a file by performing a checksum against the file's parts? We potentially have to process large files and therefore cannot keep the entire file in memory. From what I understand checksum related logic is typically stateful, allowing file data to be passed through sequentially, however it appears cache script offers only stateless functions offering a simple method of generating a single checksum hash from a single string (or stream), correct me if I'm wrong?

Hi

We have a use case whereby very large HL7 MDM messages, which contain many OBX segments, need to be processed by a custom business process. Part of the process is to iterate over each OBX segment and set a value in the same field for each segment.

Testing with a message that is ~500MB and contains over 8000 OBX segments I've encountered <STORE> errors, which surprisingly seems to be due to using SetValueAt. It appears to get through a few thousand segments before it falls over with the memory error, which I assume is because the SetValueAt method keeps in memory each preceding OBX segment?

Could someone explain how and why a HL7 ACK be showing up as a Orphaned message when I run the following SQL...
 

SELECT HL7.ID,HL7.DocType,HL7.Envelope,HL7.Identifier,HL7.MessageTypeCategory,HL7.Name,HL7.OriginalDocId,HL7.ParentId, HL7.TimeCreated
FROM EnsLib_HL7.Message HL7
LEFTJOIN Ens.MessageHeader hdr
ON HL7.Id=hdr.MessageBodyId
WHERE hdr.MessageBodyId ISNULL

I am trying to find the problem code that is causing the Orphaned messages, and an ACK showing up seems kind of Odd. While we do have Archive IO/Trace on, and Index NOT OK's set why would they show up as Orphaned messages?

Using the FHIR DEMO, I have pieced together how to make a FHIR Request using OAuth against an External FHIR Repository. When I execute the Patient search (HS.FHIRServer.Interop.Request), I get a HS.FHIRServer.Interop.Response that has a Quick Stream ID, which I then use to convert the Quick Stream to a JSON Dynamic Object. if I do a trace on the Raw JSON Object, I am able to pull out single elements, however I want to pull the raw JSON into a defined Class Structure. 

I tried using fromDao(dao As %DynamicAbstractObject) As <HS.FHIRModel.R4 subclass> outlined within Working with FHIR Data

I have an HL7 message that contains NTE segment with line break inside.

when I try to transform it (with DTL) it stops reading the message after the line break inside the NTE because it treat that as "End of Message".

Is there a way to solve this in the DTL or I need to run a pre process on the HL7 message that identify the line break inside the NTE segments and replace it with an escape char?

HI,

I'm migration an existing integration to InterSystems.  The upstream (external) system calls a JSON web service hosted in the interface engine, which converts the JSON data received to a HL-7 messages to send to the downstream system. I'm looking for direction and example of how to do the equivalent in InterSystems, so the the upstream system only has to modify the URL of the web service they call.

I suppose in IS we'll need to create a business service that is a RESTful JSON web service? How to access the JSON data (parameters in the web service call) in the Transformation?

Thank you!

I have a use case where Epic is sending an A60 Allergy transaction is set at the Patient level, but we have a system called VIBE which needs the ADT at an Encounter level instead. Currently we store ADT information in a MS SQL database for years, and we are querying it to get the latest Account Number to insert into the ADT^A60 for VIBE.

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.

Here you can read the official Meta documentation.

I'm having problems with an HL7 message that is not properly parsed by IRIS (any version, including Ensemble).

The message is a OML_O21 and is valid, in fact is similar of what is described in the document "IHE Laboratory Technical Framework, Volume 2a (LAB TF-2a) version 6.0".
This is the sample from the IHE document (paragraph 2315):

⏯ Using HL7 FHIR Shorthand

After upgrading we had 2 major problems with the new version:

- Resending messages adds blank lines.
Because we have many HL7 processes, we regulary have to resend messages if there is an outage of a server we connect with.

I am trying to work with the FHIR Object Model where I convert an incoming  HL7v2 to SDA then FHIR. From here I would like to be able to process the FHIR Object by deserializing it to a Bundle object using the following code my problem is I keep on getting an error  which is not explaining much about what is wrong with what I am doing any help will be appreciated  thanks.

Property FHIRAdapter As HS.JSON.AdaptorFHIR;

Method OnRequest(pRequest As HS.Message.FHIR.Request, Output pResponse As HS.Message.FHIR.Response) As %Status

Anyone here know if the Implementation Partner program is still open, and if so, is there anyone we can contact to get more details? I've tried reaching out via the form on the website, I've called and left a message, and then I called and talked to someone a few weeks ago who said they would "forward my info over", but we still haven't heard back from anyone. We just want to get more info on what it entails, but can't seem to get in touch with anybody to talk about it.
