Hi,

I have a HealthShare HealthConnect operation which uses the EnsLib.HTTP.OutboundAdapter. It is using a custom Operation class to send HTTP Post request. The request data that is sent to the operation and the response back from the operation is not  displayed on the visual trace. Is there anyway to display this data in the trace? 

Thank you for your help. 

Hi Community!

⏯ FHIR Update

In Episode 8 of Data Points, senior clinical advisor for interoperability at InterSystems @Russ Leftwich joined the podcast to talk about healthcare interoperability standards. In the first part of our two-part interview, Russ tells us about the history of healthcare standards and electronic record-keeping, some of the biggest challenges in the field, and how software has evolved to meet those ever-growing challenges.

Hello,

We would need to convert a message from the following class:

Class Mensajes.Request.Laboratorio.HL7Request Extends Ens.Request [ ClassType = persistent, ProcedureBlock ]
{ Parameter RESPONSECLASSNAME = "Mensajes.Response.Laboratorio.ACKResponse";

Property mensaje As %XML.GlobalCharacterStream(CONTENT = "MIXED");

Property idPeticion As %String(MAXLEN = "");

Property ExpedienteUsuario As %String(MAXLEN = "");

Property MessageId As %String(MAXLEN = ""); Property ContentType As %String(MAXLEN = "");

to a Request message which is composed by hl7 segments:

Class Mensajes.Request.Laboratorio.

Hi Community,

We're pleased to invite you to join the upcoming InterSystems IRIS 2020.1 Tech Talk: API-First Development on May 5 at 10:00 AM EDT!

In this week's InterSystems IRIS 2020.1 Tech Talk, we'll discuss API-first development and how InterSystems is embracing this industry trend with our API Manager, and specifically with our FHIR offerings. First, we'll talk about InterSystems API Manager. This tool controls your web-based API traffic in a single location. You can throttle throughput, configure payload sizes and whitelist/blacklist IPs, among many other features.

FHIR stands for Fast Healthcare Interoperability Resources. Release 4 brings this HL7 standard to maturity, and the FHIR R4 support in InterSystems IRIS for HealthTM is big. You'll learn how to work with FHIR data in InterSystems IRIS, and see our developer portal in action, where you can access FHIR resources using the OpenAPI specification.

- Currently we are receiving one NTE (See Below) from the source system

NTE|1|Result Comment|TESTING:\.br\\.br\This is a test results.  \.br\\.br\This test is a Test.

- We would like to create multiple NTE segments and send to destination system by using ".\br\"(Line Break)

NTE|1||TESTING:

NTE|2||

NTE|3||This is a test results.

NTE|4||

NTE|5||This test is a Test.

Bit we are running into compile issue on the code block.  NOt sure if there is a better way to do this.  Any help is greatly appreciated.

Hello Everyone , Good Day ! I have a question regarding the implementation of USCDI (US Core Data for Interoperability).

Why USCDI was introduced? What is the disadvantage of previous process ( communication between systems using concept like HL7) ? What is the impact of implementing this concept in existing systems ? Do we have to change logics for processing the messages? Will it effect the existing work flow of all the healthcare application?

InterSystems and Intel recently conducted a series of benchmarks combining InterSystems IRIS with 2nd Generation Intel® Xeon® Scalable Processors, also known as “Cascade Lake”, and Intel® Optane™ DC Persistent Memory (DCPMM). The goals of these benchmarks are to demonstrate the performance and scalability capabilities of InterSystems IRIS with Intel’s latest server technologies in various workload settings and server configurations. Along with various benchmark results, three different use-cases of Intel DCPMM with InterSystems IRIS are provided in this report.

Ensemble beginner here. One of the downstream applications requires to send two A02 messages instead of one A17. We do it easily in Cloverleaf - either in translation or TCL. How do I create 2 target messages out of one source message in DTL? 

Hello,

I am playing around with an HL7 business rule set and a EnsLib.HL7.MsgRouter.RoutingEngine component. I'm wondering how I can get the routing engine to fire a rule when a response is received from a business operation.

I have a simple "debug" statement in my rule to log the "Source" value when a message is received. This debug statement only seems to fire when the message comes as a request from the business service (trace item #1 below).

⏯ Collecting Healthcare Data with Alexa

Hi,

My customer is implementing HL7 validation using EnsLib.HL7.Util.Validator.Validate in an HL7 production.
They set validation spec "dmr-z" because they want to allow unrecognized Z-segments and verify the presence of required fields.
Despite using "-z", Z-segments are not allowed and the following error occurs:
<Ens> ErrGeneral: Cannot validate segment schemas without a category.Unable to validate segment 8: ZPR.
Aside to that, when the verification spec is “dm-z”, the Z-segment is allowed as expected.
Can 't "r" and "-z" be used together? 
Is there any other way to implement both validations?

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 ?

Hi everyone, 

I have just started to use JavaGateway and I didn''t encountered so much difficulties since I've got the output of the Java class I have called. 

This is the class I have implemented: 

 Method OnRequest(pRequest As EnsLib.HL7.Message, Output pResponse As EnsLib.HL7.Message) As %Status
{
set MDMarchiv=pRequest.OutputToString()
$$$TRACE(MDMarchiv)
#dim RPConverter = ##class(training.hl7.HL7toRP).%New()
set output=RPConverter.hl7toRp(MDMarchiv)
$$$LOGINFO("after transformation: "_output)
set RPStream = ##class(%FileCharacterStream).

Hi -

I was recently working with an HL7 message processing production, and some of the HL7 messages were failing the HL7 message router's configured validation. In this basic context, the messages were delivered and then the router would log an event for the message and move on to the next message in the inbound queue.

hi 

A newbie question. I am trying to use Data Transformation Editor to transform NTE segments into additional OBX segments.  At the moment I am getting both segments OBX and NTE trying to populate a single OBX. Can this be easily fixed?

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:

S tReq = {}.%FromJSON(%request.Content.Read())
S tInput = tReq.Message

S tMsg = ##class(EnsLib.HL7.Message).%New()
D tMsg.ImportFromString(tInput)
S tMsg.DocType = "2.3.

Can health Connect create a file in a directory, than add data  (HL7 messages) to it?

We have a customer that is not able to accept HL7 result messages that are missing OBX:3.1. I have been trying to create a function that could return a boolean value of 0 if the message didn't meet the expectations of the function.

ClassMethod IsValued(pHL7Msg As EnsLib.HL7.Message, pSegment As %String, pField As %String) As %Boolean
{
            #dim tSeg as EnsLib.HL7.Segment
            
            set tSegCount = pHL7Msg.

In a new rule I configured for a route, I have no constraint configured (so I assume it should pass everything), but I am getting an error that states "Constraints for rule failed".... ?

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?

((HL7.{PV1:AssignedPatientLocation.PointofCare}="D3")||(HL7.{PV1:AssignedPatientLocation.PointofCare}="D4"))&&(SUBSTRING(HL7.{PV1:AdmitDateTime.Time},9,12)!=0000)

Thanks
