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

My HL7 message got "AR" (rejected ack code) and went to the suspended queue. I re-submitted it (without editing it) but forgot to write down the details before doing so. It got "AA" and everything works fine from there.

Now (the next day) I want to check with the downstream system why they returned "AR" initially. Is there a way to search for the original message the got an "AR", along with any returned error message please?

Thanks

Concatenation Issue

I am trying to add a value to my concatenation string and the value is not being inserted in the right place. I am adding onto this code from another developer and cannot seem to get it to work. The only code I have added is underlined in bold red.

This is how the translated HL7 message looks:

OBX|1|CE|CDX^History||Specimen 1 Clinical History: CLINICAL HISTORY\.br\\.br\Specimen 2 Clinical History: CLINICAL HISTORY 2\.br\Specimen 1 Suspected Clinical Diagnosis\.br\Specimen 3 Clinical History: HISTORY 3\.br\Specimen 2 Suspected Clinical Diagnosis

Hi,

My HL7 interface in production is outputting messages to a HL7 File Operation and a EnsLib.HL7.Operation.HTTPOperation. There is no errors in the File Operation, but the HL7 HTTPOperation is giving ERROR #5911: Character Set 'iso-8859-4' not installed, unable to perform character set translation. Both the HL7 File Operation and HL7 HTTP Operation are using latin1 for Default Char Encoding.

What is ERROR #5911 about? Is something missing in the IRIS installation?

Message data global

Hello,

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?

Hi Team,

I am converting xml message into HL7 message but the input XML message contains pdf which is converting into base 64 and getting mapped to OBX:5.5 in HL7 message and sending it to downstream

In Downstream service i am using normal HL7 TCP class EnsLib.HL7.Service.TCPService but the message looks like below i am not sure why stream is taking as another segment in HL7 message,

Any thoughts on this?

Thanks,

Smythee

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.

Implementing a counter for OBX

Hi Team,

I am trying to use the inbuilt class: EnsLib.HL7.Service.FileService to pass through an HL7 ADT message as a part of an HL7 to FHIR transformation. We have a client requirement, where we are receiving an NTE segment as a part of the ADT message. I am trying to map the NTE segment to an OBX Segment. I need to implement a counter for OBX segment whenever a NTE segment is found and map the NTE fields to the new OBX segment

How do I implement the counter for OBX?

Thanks

Santosh

I'm facing an issue while converting an ORU_R01 HL7 message to XML, specifically with the <pidgrpgrp> kind elements. When I use the getvalueat() method before conversion, the XML includes the <pidgrpgrp> and other <grp> elements, but when I don't use the getvalueat() method, the XML is generated without these <grp>elements.

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.

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:

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:

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

Rule logic

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.

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!
