Question Ravi Akkiraju · Mar 16, 2017

noob here..(moving from JCAPS to Ensemble)

We are wondering where is the best place to tie the schema category for an incoming HL7 message? Should we do this within the service (via the message schema category setting) or receive everything and validate in the process (DTL) level?

We want to capture everything that will be sent to that HL7 listener service and then decide what to do with bad messages at the process layer.

Does anyone have any recommendation regarding this? Appreciate your input and decision thought process.

Thank You,

Hi, 

We have a mixture of legacy and new systems, and are grappling with the issue of moving documents between systems.

At the moment we are mostly using file drops and encoding metadata in filenames, but a new supplier (letter transcription) is going to provide a Hl7v2 feed sending MDM^T02 messages with PDF's of letters base64 encoded in the message itself.

We are thinking of asking all our suppliers to go with MDM (or ORU) for sending documents. 

I'm interested in the pros and cons of the options; and if there are options I haven't thought of. 

This is the options I have so far;

Question Vijay Share · Mar 3, 2017

Hi

I need to process a very large Batch file which contains HL7 charges which we pull using FTP. I need to loop through the file and do some checks and then split the large Batch file in to individual messages. These individual messages then gets process through a different module to create a output batch of different format

Hi all,

We have a big problem with spanish accent and special characters using Data Transformation (HL7 Messages).

We have some DT to transform HL7 messages to other type (OUL^R22 To OML^O21) so it copys the PID segment to the new one, but if in the PatienName field has any special character, the transformation stops and it not continues with the transformation.

This is the message

Question Alok Saldanha · Nov 15, 2016

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 have a project to convert a JSON message with two patient identifiers into an HL7 ADT^A31.  Is there any documentation or training that you would think is appropriate?

Currently using Ensemble 2014.1.5 on AIX

Question Andrew Makinson · Nov 22, 2016

Hopefully somebody can help with this :

Using healthshare - Ensemble::: I have an HL7 message (ORU^R01) where I have an RTF file embeded into an OBX segment as what appears to be plain text.

example below :

How would I  extract this file out and create an email and attach this RTF file as an attachment?

Question Scott Beeson · Aug 18, 2016

I see the TS and DT data types in the default 2.3 schema:

<DataType name='TS' description='time stamp'>
    <DataSubType piece='1' description='time of an event' datatype='ST'/>
    <DataSubType piece='2' description='degree of precision' datatype='ST'/>
</DataType>

<DataType name='DT' description='Date (2.8.13)'>
    <DataSubType piece='1' description='Date (2.8.13)'/>
</DataType>

but it doesn't appear that it would actually validate the format. Is this possible? We had an instance recently where a customer was sending a timestamp with a missing digit (20160503120 for example)

Question Alex Van Zutphen · Oct 11, 2016

We are interfacing through Ensemble with an application that does not like diacritic signs in text. I have been searching for a way to strip these signs from the HL7 messages that get send to that application. 
The problem in short is we have an incoming HL7 message with e.g. é (or ë, á etc), this goes into Ensemble. In the outgoing message the é should be replaced with an e. 

I have tried solving this issue with the use of a new subtable, which does the conversion as é->e / ë->e etc. This works with (file)streams and also with ZConvert: Write $Zconvert("ë","O","BASCII")outputs "e", where BASCII

Question Paul Riker · Oct 5, 2016

I'm trying to read PID-3 and route the message based on if a certain prefix existed, but I keep getting Property Does Not Exist.

I've tried

HL7.(PID:PatientIDInternalID()) Contains "COS"

HL7.(PID:PatientIDInternalID(1)) Contains "COS"

HL7.{PID:PatientIDInternalID()} Contains "COS"

HL7.{PID:PatientIDInternalID(1)} Contains "COS"

This is a 2.3 MDM message. Thanks!

Framing refers to the characters that mark the start and end of an HL7 message (or other types of framed messages).  Most HL7 services and operations have a Framing setting that allows the user to define this framing.  The most common choices are available as defaults, but with the AsciiMM/NN setting, components can be configured to recognize any framing characters.

The most common framing error is ErrEndBlock.  Other typical errors include a warning saying "Discarding received non-HL7 data", a warning saying "Returning unused unexpected n-char segment", and "Discarding leftover input ''".

Question Paul Riker · Aug 9, 2016

We want to isolate the storage of our CCDAs from our HL7 V2 data, but keep them under the same namespace. From my understanding, I should create a new database then store those classes related to CCDAs in that database. Is this the correct approach?

Question Scott Beeson · Jul 29, 2016

I'm doing some Schema changes.  I used our existing standard schema as a base, which was already based on 2.3.  So let's call our existing one Custom.MHC.Schema (based on 2.3).  I created Custom.MHC.Schema.Advanced (based on Custom.MHC.Schema) and copied down one of the code tables then made a change to it.

When I ran a message through, the code table change didn't show up.  I noticed in the message viewer that the DocType is still Custom.MHC.Schema:ADT_A01 but the DocType Category is Custom.MHC.Schema.Advanced.

I have changed the HL7 Service Message Schema Category setting and I also tried sett

I have a tool I absolutely love for HL7 v2 analysis and manipulation. It's called 7edit.  I'm wondering if there is anything similar for HL7v3/CDA/CCD.  I know it is considerably more complex, but I still have hope.

So far the best resource I've found is http://www.cdapro.com/.  I'd love to hear anyone else's tips for tools or resources.

Question Steve Shaw · Apr 14, 2016

Hi,

IHAC who is trying to connect Ensemble to Quadramed for HL7 messaging, however, it seems that in order to do this, the following is required:

"we open a passive connection to Quadramed and then listen for a connection request from Quadramed, once this is established we then send messages"

Has anyone done this before?  Is this possible with the standard HL7 components?

Thanks,

Steve.

Question Jeffrey Semmens · Mar 3, 2016

What is the recommended approach to handle the following scenario: Large number of HL7 messages are serviced via Ensemble. Those messages are then transformed and routed to an Operation which calls a web service which does a number of different activities. If will do address normalization, location geo coding, MPI lookup and resolution, and insert into a SQL Server database to stage for an analytics product. Unfortunately all of this work takes time and the first thing that happens in the web service is a lock taken out on the Patien in SQL Server. Each call can take seconds where the message

Executive Summary

InterSystems HealthShareÆ and InterSystems EnsembleÆ both provide a rapid integration and development platform with built-in capabilities for the high-speed processing of HL7 messages. For the purposes of HL7 v2 message routing the two products are equivalent in performance. For brevity, this document will just say Ensemble in many places but it should be taken to apply equally to both products.

We have recently completed a performance and scalability benchmark of Ensemble version 2015.1, focusing on HL7 version 2 messaging. This document describes the observed characteristics,
