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
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".
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.

Join us at the FHIR event of the year in the US: the HL7 FHIR Dev Days 2018! A unique chance to meet 400 colleagues and discuss all topics relating to your field.
InterSystems is proud to be the Host Sponsorof HL7 FHIR Dev Days for its first U.S. edition, Boston, June 19 – 21st! We support the HL7 FHIR standard as it is critical for rapid innovation. FHIR can be used as an accelerant to bring all the information that matters for a patent into a unified health record.
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.
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.
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?
The InterSystems FHIR® Sandbox is a virtual testing environment that combines HealthShare technology with synthetic patient data and open source and commercial SMART on FHIR apps, to allow users to play with FHIR functionality.
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.
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?
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.
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?
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)
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?
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?
Hi- I have a HL7 message ADT_A01 (Admit) that contains several Z segments, which don't necessarily all appear at the end of the document, like normal. See below...
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:
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.
1. I saw there are built in DTLs “FHIR.FromSDA” and “FHIR.ToSDA” to convert SDA -> FHIR and FHIR -> SDA. Similarly Do Intersystems have DTLs for HL7 -> FHIR and FHIR -> HL7?
2. The reason why I am asking is, I see in HSLIB namespace HS->GateWay->HL7->HL7toSDA3 and HS->GateWay->SDA3->SDA3toHL7 DTLs. Like-wise I am trying to locate HL7 -> FHIR and FHIR -> HL7. Please help me to locate them
Are there any utilities/api in HealthConnect 2016.2.1 that will allow conversion of XML virtual document to Json format? We were thinking to convert HL7 ADT message to XML via Ensemble DTL and then send it to another BP to convert to Json format for transmission via Web Services. To my understanding there isn't anyway to represent Json as a virtual object so it can be use for direct mapping of HL7 2.x message to Json via Ensemble DTL.
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?
Ensemble 2015. Working on an a way to send NACK'd HL7 messages to a flat file for external review/troubleshooting. (Similar to the way BadMessageHandler deals with validation errors.)
I think I have the Alert piece down, but need assistance with the exact syntax to do an SQL query in the DTL (or a custom function) to pull the HL7 message Raw Content into the Alert, based on the SessionID.
(Also, anything special to write alerts to the File Operation?)
