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

Hi Developers!

InterSystems FHIR contest has been started and in this post, I want to introduce several topics you may find interesting and use to build FHIR applications with InterSystems IRIS for Health.

Amongst them are:

  • a frontend mobile or web app for FHIR server FHIR REST API or SQL;
  • Backend apps to perform complex queries and maintain rules;
  • work with different HL7 data standards.

See the details below.

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

I'm looking for options to create multiple DFT HL7 messages based on data contained in a ZCO segment in a single inbound DFT message. I have the following ZCO segment:

ZCO|CCC^Charge Code|1306794,1071301,23510,1071424|MFCD^Charge Code|14232,3542|||||

In this example, I need to create a new DFT message based on the data contained in ZCO:2. Each code needs to be in it's own DFT message and put in FT1:7.1. The number of codes will vary for each inbound message, but each code will need to create its own outbound message to the client.

HL7 field for base64 in orl

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

Epic had changed some of their logic on their Incoming Radiology Results which now require an Ordering Provider even though it is supposed to account for it within the Epic Interface settings.

I was wondering if we are using a custom schema if there was a way to default a value into OBR:16 if it was not valued without having to modify all the DTL's for these Results.

Is there a way to set this via the schema editor or in the background so we don't have to create/update DTL's or create a custom TCP Operation Class??

Has anybody encountered this before?

I did a very usual hl7 adt transformation DTL, but it is with a customized schema, like ADT_ALL, it is a structure that tries to cover all the ADT schema scenario so we can use 1 type for all ADT messages.

the DTL tests fine in DTL test, with all the segment transformed correctly, but once I put it to test, to send message through source and the message after transformation can only go to MSH, EVN, but won't transform other segment like PID etc.

Background:

This guideline provides an overview of how to design and implement a REST API interface for querying patient demographic data from an Electronic Patient Record (EPR) system using HealthConnect. The process involves sending a query request with the patient's identification number, retrieving the response from the EPR system, extracting the required patient demographic data from the HL7 message, and sending it as a JSON response to the supplier. The high-level process diagram is shown below (Screenshot 1).

This article will describe and include an example of how to embed an external PDF file into an HL7 segment, specifically ADT_A01:2.3.1 OBX(). This can be useful when attempting to insert pictures or other external data into an HL7 message. In this example, the name of the PDF file to be embedded is provided in the incoming HL7 message in OBX(1):ObservationValue field.

Message Profiling

Hi all,

I was wondering if InterSystems offers any message profiling capabilities. What I mean by "message profiling" is essentially stats or metrics gathered from a collection of data submissions of a particular type. For instance, average number of segments <XYZ> in a specific HL7 V2 message type. Or the number of sections found in a HL7 V3 CDA documents.

Curious if there is anything like this provided "out-of-box".

Thanks!

James

For testing purposes, I would like to create an EnsLib.HL7.Message from either a %String or a file on disk and pass it into a function in a unit test (outside of an Ensemble context). EnsLib.HL7.Parser appears to do the necessary parsing, but it also sends the message via Ensemble service rather than returning it as a value. Is there a way to leverage the parsing outside of a Ensemble service? Alternatively, is there another way to create an EnsLib.HL7.Message?

I need to remove content below, from PID-3/HL7 message, in IRIS. However, I need to keep the content in PID-3.1. For example, I’d need to keep only, “5050532”. Can this be done in Data Transformations? If yes, how?
Thank you!

We are seeing ERROR #5002: Cache error: <MAXSTRING>zSaveData+14 ^EnsLib.HL7.Segment.1 come up on a Routing rule when we are trying to Encoded PDF's through a DTL. In the DTL we are copying source to target. Is there a limitation on trying to copy source to target?

At the bottom of the DTL you are see that we commented out converting the Encoded PDF to a Stream, is it recommended that we always use %Stream anytime we are dealing with PDF's?

Thanks

Cache Query for HL7 NACK

I would like to capture any NACK's that is sent back to the Operation. The Operation is already setup to "Save Replies/IndexNotOK's", but I would like to see if we can query Cache and pull those NACK's into an extract.

Is this possible?

Thanks

Scott

Hello,

is it possible to kill/suppress hl7 message in the DTL (data transformation).

in cloverleaf, it is common practice to check the value in message, for example pv1:7.9. if the value is certain word(assigning authority) then send the message over to destination, if it is not, kill the message

how would this be done in InterSystems ? does that need to be done in the rule instead? or can it be done in the data transformation? if it can be done in data transformation, how can it be done?

Thanks

Trying to start investigating an error we are seeing with multiple of the same messages getting sent to the same vendor. We receive an HL7 message with an RTF embedded from our EMR, send it through a DTL to just update the Patient Class, and then send it onto the Operation which is TCP.

We are starting to see this error message...

Hi all! 2nd time poster and still kind of a newbie. I Googled and searched the posts but did not find anything quite like my question. I have an XML to HL7 2.6 MFN_M16 translation. I created an XML schema and I am using it inside a DTL to translate data to HL7. The XML is rather simple EXCEPT one element as data separated by pipes. This only happens when one item has multiple PAR Locations. To make a valid HL7 message these multiple PAR Locations each need their own IVT segment.

XML Par Location is equal to HL7 IVT:InventoryLocationIdentifier OR (IVT-2)
