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.

Hi Community, 

Can I please check if any one is aware of any functionality in HealthShare to verify NHS Number check digit.

We are trying to implement the NHS Number check digit validation using Modulus 11 Algorithm ( described here : NHS NUMBER (datadictionary.nhs.uk) ) 

I wanted to check if there is any built in option available or if anyone has implemented something similar using Object Script. 

Thank you for your help.

Introduction

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.

How can i modify file extention on output file leaving Busness Operation

Ex..changing "output.txt" to "output.hl7"

This question originally appeared in the comments of the post: Making use of Multiple Sub Transforms in a main map || HL7
 

I'm having a similar problem trying to get PRD(1) into PV1:ReferingDoctor and PRD(2) into PV1:ConsultingDoc
Running the subtransform will populate referring doctor for the first PRD, and then the second running will delete the PV1, make a new one with only the consulting doctor populated.

Was hoping I could use a subtransform to populate the information, but looks like it has to be done at the transform level.

Hi everyone,

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.

Thank you

Good morning,

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.

We have been creating and testing two variants.

Hello,

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:

Class Mensajes.Request.ConsentimientoInformado.HUC.ORUHL725OutRequest Extends Ens.Request [ ProcedureBlock ]
{

Parameter RESPONSECLASSNAME = "Mensajes.Response.ConsentimientoInformado.HUC.

A "big" or "small" ask for ChatGPT?

I tried OpenAI GPT's coding model a couple of weeks ago, to see whether it can do e.g. some message transformations between healthcare protocols. It surely "can", to a seemingly fair degree. 
It has been nearly 3 weeks, and it's a long, long time for ChatGPT, so I am wondering how quickly it grows up by now, and whether it could do some of integration engineer jobs for us, e.g. can it create an InterSystems COS DTL tool to turn the HL7 into FHIR message? 

Immediately I got some quick answers, in less than one minute or two.

Hello Community,

The Certification Team of InterSystems Learning Services is excited to announce the release of our new InterSystems HL7® Interface Specialist Recertification Project If you hold the InterSystems HL7 Interface Specialist certification AND your certification's expiration date is within 6 months of today's date, you can get recertified by successfully completing the recertification project. Completing an InterSystems recertification project is one of two options a certification candidate can choose to get recertified (the other option is to take the new version of the exam).

Hello,

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:

Try {
     Set pdfStreamObj = source.StreamGet()
   } Catch {
      Quit
   }

 //Set PDF stream object into OBX:5
   Set status = target.

Hi,

I have a ORU message, which has a EVN segment that I want to remove and send the message across.

I tried to clone the request as below:

s newreq = request.constructClone

s changreq = newreq.RemoveSegmentAt("EVN")

Set request  = changereq

but it fails. Is there a way that I can safely remove a segment and pass it on?

Would appreciate your help in this

Regards,

Eric

Hi community,

I am trying to map  <assign value='source.{ORCgrp(1).RXE:7.1}' property='target.{ORCgrp(1).RXE:7.1}' action='set' /> in data transformation 

My input value for source RXE isRXE:7.1 will be like Keep orders~New orders  ~       ~ new orders

 After mapping i am getting only First repetition value i,e is only Keep orders value  

I have tried using $EXTRACT like this <assign value='$EXTRACT(source.{ORCgrp(1).RXE:7.1},1,*)' property='target.{ORCgrp(1).RXE:7.1}' action='set' /> in data transformation  still getting First repetition value in target message

How to get full 7.

We have this intermittent issue with a particular supplier message , just wondering if anyone has further insight around the two errors we get when we see this. 

We use the out of the box TCP hl7 adapter. 

We first seem to get this incomplete hl7 message resulting in an error like 

Discarding leftover input 'MSH|

This is not unexpected as the final obx has not dot the description of OBX:2.2 ect. 

OBX|53|TX|NCDAC^

The next message will have the error 

If you hold the InterSystems HL7 Interface Specialist certification, you can potentially get recertified and have your certification expiration date extended by five years by beta testing our new InterSystems HL7 Interface Specialist Recertification project. The project includes hands-on exercises to validate core skills for developers who use InterSystems products to build and test HL7 v2.x productions. During the beta period, which extends until October 31, 2023, anyone who holds the credential is eligible to try the project, and the standard $150 fee is waived for candidates.

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.

Did you know that with InterSystems IRIS for Health™, you can create a FHIR Facade that enables healthcare apps to send and receive HL7® FHIR® data?
 Find out how in this learning path (3h 30m), which includes a hands-on exercise (20m).

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.
 

Analyte: HCG, Value: 1968, Unit: mlU/mL 

Reference Range:
Week of gestation: 3, Range: 5.8-71.2
Week of gestation: 4, Range: 9.

In an HL7 Business rule I am trying to block ONLY ORM messages that have a PV1:3.4 of 105 or 205 and a OBR:4 value of EP22 or CATH01.

I created the logic below but it appears to be evaluating the two fields independently instead of combined?

Here is what I had.

(((HL7.{MSH:SendingApplication.NamespaceID}="Epic_Cupid")&&(HL7.{ORCgrp(1).ORC:OrderControl} IN "NW,CA")))&&(((HL7.{PIDgrp.PV1grp.PV1:AssignedPatientLocation(1).Facility.NamespaceID} NotIn "105,205")&&(HL7.{ORCgrp(1).OBRuniongrp.OBRunion.OBR:UniversalServiceIdentifier.

Hi

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.

This end system wants us to send HL7 messages completely asynchronously, one after the other without waiting for any form of ACK or NAK.

Does InterSystems has CDS Hook implementations? if yes, where I could get the details.

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.

If you're interested in taking our InterSystems HL7® Interface Specialist exam, we highly recommend these questions.

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()

Script start

#Load dependencies

import datetime as dt
import uuid

# Cache current time in CCYYMMDDHHMMss format
hl7_datetime_now=dt.datetime.now().
