Looking at the DTL, we can pretty much understand what the provided mapping from FHIR to SDA3.

But, is there any Intersystems document, where the mapping To/From FHIR is documented, at least FHIR to SDA3 ?

Good morning -

I am attempting to pass some HL7 content (say, a complete ADT message) from one server to another via REST/JSON - for reasons. 

I can get the data across but when I try to create an EnsLib.HL7.Message object from the message in the JSON body, I end up with just the start of an HL7 msg in the resulting object. Looks like: MSH|^~\&

The start of the code accepting the data looks like this:

Hi 

I am currently working with a "Stem Cell" supplier who do not have any/much Interface capability to push "Bone Marrow" harvest information. But willing to develop an HL7 feed/ WSDL capability.

It will be ideal, if I can get this via HL7 as much as possible and wondering if anyone has used HL7 to transmit bone marrow CD34, CD3 makers, product location and Harvest information? if so can you please advise which HL7 messages are ideal and some sample messages if possible please?

How about

I am putting together a new interface to take in a CSV file and output an HL7 message.

I have used the record mapper to create the source class and I am putting together the transform, but when trying to test it I am not seeing the data populate the HL7 as intended.

I have a colleague that is trying to eliminate any HL7 transactions that have admit date/time of midnight from going to an downstream system within a routing rule. I have tried several different iterations of code trying to figure this out just in the routing editor. Without having to write an object script function is this possible?

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,

While HL7 Errors ACKs come back in the soap response, the HL7v2 Error ACK message is not processed. 

I used the SOAP Wizard to construct my classes, but the generated code doesn't handle the HL7v2 ACK.
Does health Connect have a class that handles this?

Failing an official solution should I go ahead and make make my own classes based on EnsLib.HL7.Operation.TCPOperation, but wrapping it with the generated SOAP handling code.

How have others dealt with this?

Way back when during our Siemens LCR days we had to limit the number of characters in OBX.5 to a length of 75. That was back when we had eGate.

Now I need to do the reversal of that and take loop through a string length and split the string up into multiple OBX or NTE based on a certain length. In reading documentation $EXTRACT can do this if you know the exact length, but in this case we don't. 

So how would one loop through a string and say every 75 characters create a new OBX or NTE segment?

Thanks

Scott

Hi there.

I am dealing with a clinical system that returns a stack trace within the NACK (Specifically, within MSA:3).

Within the stack trace there is an error code I am interested in, and hoped I could use the Reply Code Actions to look for that code within the error by using the "E*<text>" condition to either suspend or accept the response and move on. The problem is, looking at the error within the event log, I can see that the error text is truncated, cutting off the error code I'm looking for within the stack trace.

Hi,

I would like to use EnsLib.HL7.Operation.HTTPOperation for sending HL7 messages via HTTP. It sends the Content-Type as "text/html"

I would like to change it to something else, say "text/plain". I cannot see a way to do it.

I have now written a custom Operation (based on EnsLib.HTTP.OutboundAdapter) and modifying the Content-Type while POSTing using SendFormDataArray(). It's bit frustrating to parse the response etc.,

I would rather prefer to use HTTPOperation of HL7. Can somebody help?

Hello,

currently we have a problem in development with the character set of the response message.

We are transmitting an HL7 message with an operation based on the EnsLib.HL7.Operation.HTTPOperation class.
We have changed this as follows.

Set pMsgIn=$$$NULLOREF, tHttpRequest=##class(%Net.HttpRequest).%New(), tHttpRequest.WriteRawMode=1, tHttpRequest.ContentType="APPLICATION/HL7-V2; charset=UTF-8"

Unfortunately, the ContentType character set is not read correctly in the response.

Hi, 

It is sometimes undesirable to send a full demographic or results feed to departmental clinical systems, that only see a subset of the patients.

While some systems (paediatrics, maternity, geriatrics) can filter on patient demographics, a number of systems are for cohorts of patients that don't fit a particular criteria.

One of our system vendors has a patient index filter service that keeps a local index of relevant patient identifiers, and only forwards matching messages.

So I have an interesting problem. I am going to be using a process and rule to determine if an HL7 message qualifies to be sent out, then using a record map to write certain aspects of that HL7 message to disk (with an HL7 to record map DTL). This is simple enough but the recipient of this file is requiring a single record map entry per DG1 segment in the HL7 message.

 

For instance if said HL7 message for PATIENT^TEST  has 3 DG1 segments, I would need to write three lines (or records) like so:

123^^^^MR|TEST|PATIENT|DG1(1) TEXT|DG1(1) CODE|DG1(1) DATE

Hello Gentlemen,

 

My Business process connector receive a Oru_01 hl7 message with an ED segment inside (Base64 pdf). How is it possible to extract it and create a pdf file within?

Here is the sample of function I have. I know it doesn't work but if you could help me, it would be perfect. Here is my function, the goal would be it create the file where I want and return me the link of the file.
