I'm receiving HL7 message containing the escape sequence \X00D\ indicating a carriage return. In the HL7 documentation I find that this is a valid escape sequence but when I read the intersystems documentation it states that only \X0D\ is valid.

What is the best way to work around this? I think that intersystems should change the UnescapeEx method in the EnsLib.HL7.Segment so that it complies with the standards.

Hi -

I'm working on a project that will be dealing with depression screening and I'm not certain where any of this information would belong in the HL7v2.x world.

Can anyone suggest what the proper placement of "has this person been screened" and if so, "this was what the screening showed"?

At first thought I was thinking that this is an "Observation" of some sort (and ORU message) for the "what the screening (or perhaps testing) showed", but I'm not sure if the screening was performed yes/no qualifies as an "ordered test".

Just looking for a starting point I guess. Thanks

Hi, 

I want to splice a PID segement returned from a query, so I can use it in a DTL:

<assign value='context.pidSegment' property='target.{PIDgrp.PID}' action='set' />

I need to set the value of 'context.pidSegment' to something I can use in the DTL objectscript expression

but I'm not sure what method (or property) to use to get the class EnsLib.HL7.Segment segment into a datatype that can be used in the DTL?

I've tried the following to no avail

I have a vendor that is sending me an Abbreviation in FT1:16.4.2 that I need to look up against a table to find the correct ID for.

FT1|1|||20180523161501|20180523161503|CG|1906551^Lipid Profile|||1||||||^^^ LAB&06CL|||Z00.00||00410^Knerr^Joel||721410||30100001^Lipid Profile|

But in my Business Process when I refer to request.GetValueAt("FT1:16.4.2") its not recognizing that this field contains information. Is my syntax wrong

Two fairly common requests we receive from HL7 customers are (1) how to remove all trailing delimiters for fields and segments in HL7 messages and (2) how to "find and replace" for an entire HL7 message (as opposed to one segment/field at a time).  The code sample below shows a custom function that solves for item 1 and by extension item 2 above.  In other words the same approach can be used for finding/replacing any sequence of chars in an entire HL7 message, with some tweaks to the custom function.

Here’s an example of how to actually call the function from DTL.  I recommend doing this as the last line of code in any DTL where it is used.  Note that “target” is used in both the value and property of the code below (as opposed to the DTL “source” message).

<assign value='##class(ISCSample.Custom.Function.ConversionScrub).ConversionScrub(target)' property='target' action='set' />

 

Here's the  sample class and classmethod:

Hi, 

We have a system that gives an AE 'Error' response for warnings, that we want to transform to AA codes when returning the Application ACK.

MSH|^~\&|iCS|EHT|EPRO|R1K|20180511113136||ACK^A02|fbwZaoKW/USAdFI3IGLU|P|2.3|||AL|NE|
MSA|AE|fbwZaoKW/USAdFI3IGLU||||0^Nothing To Update^^W
ERR|||0^Nothing To Update|W|

Fortunately they include a warning code in MSA:6.4 and ERR:4

Does HealthShare have inbuilt functionality to transform Application ACK's, or do we need to build a custom BPL or class to handle this?

Kind regards, 

Stephen

Hi Community

I've just started developing for a new client and noticed that the View Raw Contents link isn't displayed when inspecting HL7 message contents in the Management Portal. Is the link missing due to:

1) a configuration setting?

2) a security setting?

3) a difference between installation on Unix Vs Windows?

And is there a way to turn it on?

I've trawled through the doco but haven't been able to find anything on this.

Thanks in advance for any help you can give

This is a sample Ensemble/Health Connect production which demonstrates how to receive an HL7 order (ORM) inbound from a file, extract fields (in this case, basic demographic information), and insert those into a table in an external SQL database via ODBC.  

Included in the zip file:

  • Exported code
  • Sample ORM message
  • 'How to configure' doc

We have a case where a vendor can send us more information in the DICOM message rather than in the HL7 result message. In theory it should be possible to take a DICOM and convert it to HL7, stupid question is has anyone done it before? Does anyone have any good examples of a DTL they did to show me how to setup the message structures and translation?

Thanks

I'm trying to get a count of specific message type with a specific entry and thought I could build the query in Message Viewer but  this does not provide counts (as far as I am aware). So when I take the SQL from 'Show Query' it omits the segment criteria as the code shows below. 

 I have attached the criteria that has been excluded. Is this possible?

Thank yo

Hi,

I am afraid I am stuck again. I have ensemble connected with a MsSQL database and I have a service that calls a store procedure. All is working, and I can get strings from the database in the service. The problem is that the data the store procedure returns is suppose to be an HL7 message so I need to convert the string into HL7 format. I have been using the ##class(EnsLib.HL7.Message).ImportFromString  method but although I have a valid HL7 message from the string received from the DB...apparently the content of the message is being modified

Hi everybody,

I love the integration of HL7 v2.x in Ensemble, it's really easy to use.

I would love to see the same about using CDA on Ensemble. I know it's a complicated standard, but it would be more easy for developers in Europe if we could use it like any other type of message instead of using at XML level and xsl transformations.

Any experiences dealing with CDA on Ensemble?

Hi ,

     I'm using standard business service not(Customized business service). I'm not able to process the Hl7 data file which contains CRLF characters.It shows warning "Discarding  Received non HL7 data". Actually it discards some segment after CRLF character. Is there any settings to overcome this problem?

 

Also i tried UTF-8, Ascii,Unicode.. characterset . But it won't work. Please help me .

 

Urgent!!!

As I was going though and trying to figure out why our CACHE.dat has increased in size over the past 18 days, I found that EnsLib_HL7.Message is still retaining messages dating back to 2014 even though we have our purge set to 10 days. Has anyone else experienced this?

Thanks

I am trying to come up with a way to decode the Base64 we receive in an HL7 message into a PDF file and save it in a directory on our AIX machine. I thought I had the following working at one time but I am having issues. Has anyone done this before

Is it possible to have a, b, c, d, e, and f as a counter instead of the counter being numeric? See below...Epic would like us to set OBX.4 using a alpha numeric combination.

OBX|4|ST|69548-6^Genetic Variant Assessment|1.a|Mutation IDH1:Not Detected||||||F

OBX|5|ST|69548-6^Genetic Variant Assessment|1.b|Mutation IDH2:Not Detected||||||F

OBX|6|ST|69548-6^Genetic Variant Assessment|1.c|Mutation NPM1:Not Detected||||||F

OBX|7|ST|69548-6^Genetic Variant Assessment|1.d|Mutation RUNX1:Detected||||||F

OBX|8|ST|69548-6^Genetic Variant Assessment|1.e|Mutation TET2:Detected||||||F

OBX|9|ST|69548-6^Genetic Variant Assessment|1.f|Mutation TP53:Not Detected||||||F

I have an interface that does not send me specific ID's, so I am scanning the AIL3.2 (Text) field for certain characters. The Routing rule is getting pretty big with all the OR statements. Is there a way that I can define what I am searching for in the data lookup table, and not have to scan the whole field that it does by default? Is there a way that I can simplify this

Hi everyone,

I started working on Ensemble this year so maybe I am not implementing the right way. I'm trying to connect a Welch Allyn monitor to TrakCare. The workflow is the following:

- User scans patient number with the monitor.

- The monitor sends a QBP_Q22  message to request patient information

- Ensemble (or TrakCare) sends back a synchronous RSP_K22 containing the patient data (name, dob, sex)

- The user checks the patient's information displayed on the monitor, takes vital signs and sends them to TrakCare (via Ensemble)

 

I designed a DTL to build the RSP_K22 message using a query that retrieves information from TrakCare database with ODBC. My problem is that the monitor cannot receive messages from a standard Business operation. It only receives the ACK Ensemble sends back.

With other french colleagues, we found an old discussion that really looks like what I am trying to d

So this may sound trivial, but I'm seeing conflicting information on this topic and hoping to get clarification.

 

According to Enslib.HL7.Message class definition, the maxlength of RawContent is 10,000 characters. So when using encoding like UTF-8, that is 10KB. When using Unicode, that should then be 20KB.

But then also coming across some forums and documents where 32KB is maximum size before HL7 fields are truncated.

 

What is the sure way to determine and modify an interface's maximum supported message size?

Hi-

Please excuse my rather limited knowledge of HL7.

In Ensemble, I have a HL7 message that contains several Z segments.  I have created a custom schema to represent the new Z segments along with the new DocType Structure and Message Structure

How does Ensemble/Health Connect know which custom schema to use?  I believe it has to be indicated in the MSH segment somewhere, but not sure where exactly that would be.   Is the version simply updated with the new schema name or is there some other field?

TIA

Ken

Dear All,

I'm to create a HL7 business operation that uses the Enslib.Email.OutboundAdapter  to create and use AttachStream() to create a file attachment of the HL7 contents, using the RawContent property of a Enslib.HL7.Message.

The class compiles okay, however   when I send a message to the class I get the following error
