I want to test automatically that HL7 business operation works correctly in error conditions. One is to test CE acknowledgement. I have planned to implement test production which includes business services for different situations (AA, AE, CA, CE, timeout, late response etc).

How should I implement HL7 business service that always returns CE (commit error)? I have tried but it keeps returning "AA".

Hello,

I am trying to send a HL7 Billing Batch 2.3:FHS file out to an FTP site:

The file needs to be in Variable Length / Carriage return carriage control format--

When I send the file, the format is Fixed Length 512 Byte Record-- Not Working

The data is ok within the file-- It is just the way I am sending it out of Ensemble that is not correct.

I am thinking that it is a setting within the Operation that I am missing or not choosing correctly.

Operators as Variables

We have the need to write a function that can loop through say a field in an OBX segment within HL7 and compare it to a string passed. Is it possible to have the user enter the Operator ( >,<,=,<>) as a variable inside Cache object script? Does anyone have any examples they can share?

Thanks

OBX 5 and CRLF

Hello,

I have some issues trying to store a base64 encoded stream into the obx:5 segment.

I'm using the StoreFieldStreamBase64 method in my business process to store the stream into the segment.

I'm sending the hl7 message containing my stream to an ensemble business operation (EnsLib.HL7.Operation.FileOperation) to write the message on disk.

When i'm reading it with an ensemble business service, it can't parse the stream because it contains multiple CRLF.

Why is my business operation splitting my stream into multiple newlines ?

Remove FHS segment from file

Is there any out of the box capability in Ensmeble to remove an FHS segment from a batch file? We have a client that is creating a batch of HL7 messages and they insert an FHS but there is no trailing FTS.

We are hoping to avoid custom COS code to handle this scenario.

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".

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?

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.

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

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

DICOM to HL7

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

HL7 segment query using SQL

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 you

CDA on Ensemble?

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?

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?

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?

Custom Schema

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

HL7 Email Operation

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:

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)

For a HL7 production, How will I be able to use two different segment level transformation (sub transform) in the main transform.

For Ex:
Few mappings from source PID --> target ZAX segment (subtransform 1)
Few mappings from source PV1 --> target ZAX segment (subtransfrom 2),

In the main mappings, I have used subtransform 1 followed by subtransform 2. It doesn't seem working fine.

Any suggestions please. Thanks:)

Purge for "IO Log Input Data"

Hello mates,

When turning on the “Archive IO” option within the business operations, it provides us the capability of seeing the input and output communication with external systems. For instance, watching the messages sent out + ACK message sent back .

Our production has got a scheduled task that runs daily (by default I guess, as many others) and is in charge of purging “Errors and log files”. And this is likely to be linked to the “Archive IO” feature, right?

Hi

I've got a Service that get ACK Messages originated by another system.

I want to get the details of a Message when the ACK is CE (Failed Message).

I don't know whether this is the best approach but, at the moment, I have a DTL and I would like to search the Cache Database for a Message with the Control ID on the ACK in the MSA segment.

Any help with this would be great.

Tks.
