Hi,

What is the best practice when adding FHIR extension to Patient resource? To not to lose it when updating Patient base class etc.

Hi,

I've been trying to create a patient using FHIR, but all I seem to get back is:

{"resourceType":"OperationOutcome","issue":[{"severity":"error","code":"invalid","details":{"text":"FHIR create interaction invalid for this end point"},"diagnostics":"FHIR create interaction invalid for this end point"}]}

I've tried a variety of requests and read operations work, but create doesn't seem to. Has anyone run into this? Any ideas? Thanks.

Hello Greetings-

I am exploring on converting HL7 to FHIR.

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

3. If there are no built-in DTLs for converting HL7 -> FHIR and FHIR -> HL7, what is the process to achieve this?

Thanks much in-advance.

Thanks,

Surya

Hi, 

We have a PAS that accepts HL7v2 QBP^Q21 requests, and returns patient details in an RSP^K21.

We have a clinical system that wants to sent an http GET request of the form http://server/getpatientbyid?pid=M1234567

So I think I need to convert the query url into a QBP^Q21 (HL7) message, then take the response in HL7v2, convert to SDA, convert to FHIR, and put that in the response to the  original GET.

Does anyone have any experience doing this? is there an approach you would recomend?

Working on implementation FHIR to my project, I found interesting project HAPI-FHIR, which could help me to quickly launch my FHIR api server with InterSystems Caché as a storage, because this projects uses Hibernate to connect to database, as an example they use DerbyDB. I tried to change settings to use InterSystems Caché, but unfortunately it does not work and throw some errors inside HIbernate. As I found in Caché documentation, I have not some many options, I just have to set Cache dialect, and set database url.  This projects uses Hibernate 5.

Can you connect to FHIR through ensemble or do you have to have HealthShare to connect to FHIR services?

Hi, 

Most of my development experience is with HL7v2 interfaces and I don't have a background in web development and I'm very weak with javascript.

I'm looking for suggestions of learning resources to learn FHIR  and 'SMART on FHIR' (JavaScript, OpenID connect, OAuth2) for developers like myself who mostly do HL7v2 integrations - but see FHIR as the future - and want to develop their skills!

I've found these

• http://docs.smarthealthit.org/tutorials/javascript/

Hi,

I've successfully installed and configured the custom MESH API supplied by intersystems. I'm able to send HTML rendered documents directly to GP's using Kettering.xml. 

Ideally, I'd like to be able to send PDF/RTF files rather than HTML. Is this possible and if so can I still use Kettering xml? I know FHIR is the preferred method of transmission but i've tried sending a test FHIR message through MESH to EMIS but it's not displaying so I'm not sure if EMIS is able to display FHIR formatted messages. 

Thanks.

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,

Here are the requirements for implementing a new project using FHIR and JSON.

The FHIR JSON resource types - Patient, Encounter, etc. - need to be converted to HL7 messages using DTL.

Does %JSONImport() allow direct conversion of JSON into HS.SDA3.Patient objects?

Could anyone suggest an easy way to convert FHIR objects for DTL use?

Hoping someone can help.

I had posted a similar question outside this group a while ago "Errors requesting data from local Ensemble FHIR Repository" but haven't had the chance to follow up on it since. It was suggested I re-post inside this group.

I'm trying to request data from my local FHIR repository using a simple JavaScript client and am getting the following CORS errors . ( It is a standalone client not inside HealthShare without CSP etc. on my localhost ).

Hi,

How to send PDF/Image as attachment along with FHIR Resource.

Thanks

Is there any good documentation/tutorials on creating gateways in both directions between FHIR and Hl7v2 (for Health Connect)?

the scenarios I'm most interested in

1. Client application sends a FHIR demographic query to Health Connect - and the interface has to convert this to Hl7v2 QBP^Q11 message to the PAS.

2. Health connect sends a PDF document (from a file or HL7v2 interface) to an EPR over FHIR.

Thanks

UPDATE

We are using Health Connect  15.03 - Cache for Windows (x86-64) 2017.2.1 (Build 801U) Wed Dec 6 2017 09:07:51 EST [HealthShare Modules:Core:15.03.9901 + Linkage Engine:15.03.

Hello All,

   Having a recent project to create a FHIR repository, I want to know (as looking at the code) if HealthShare FHIR implementaton supports subscriptions?.  I know it records the subscriptions ok, BUT does it handle sending the subscription out (based on the tags) to an endpoint (i.e. when a new FHIR request commits data that would trigger the subscription) ?, I'm 50% it doesn't, but would rather find out for sure before shoe horning something in.

Hello everyone,

Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.

Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.

The performance meets the requirements, even with much larger requests than the one exposed above.

I am attempting to POST a Bundle containing a resource to an ISC-based Resource Repository. Documentation says "batch" interaction is fully supported - so I assume this is possible.

I post to the FHIR base URL, but I get the following back: " The requested URL /customfhir/r4 was not found on this server."

The bundle I use to post to create a patient resource is very simple (see below). I am using a request.method of POST because I want the Resource Repo to create a new fhir resource id.

I'm using Postman to generate the request.

Hoping someone can help,

I have the "Sample FHIR Production" installed ( as described in the documentation) with the following Components:

Service: HS.Gateway.ECR.SDA3XMLFileService

Processes: HS.FHIR.FromSDA.DTL.Transaction.Process

Operations: HS.FHIR.Repository.Operations

When a patient's data gets updated in my application a new SDA3 message is generated and processed by the FromSDA DTL. The Repository Stores that data as a New patient ( i.e. when I query the Repo they have different IDs "resource":{ "resourceType":"Patient", "id":"4", ) .

Hi Community,

I need to convert HL7 Message into FHIR Format.Can anyone share basic reference for FHIR ADT^A01 message?

For converting HL7 message to FHIR we need to convert HL7 to SDA3 format and then converting SDA3 to FHIR format.

Please Share few basics steps for converting SDA3 to FHIR message?

Thanks

The product I'm using is HealthConnect ( this installation HSAP-2017.1.1.111.0.17521-hscore15.03-b8382-win_x64.exe). Do I have access to the Information Exchange Clinical Viewer ? Is there a way to install this and connect it up to my HealthShare FHIR repository?

Hi guys,

I'm helping our client to pass a Chinese CHIMA FHIR certification, which requires to search  encounter by subject(Patient) name.

I noticed that in FHIR specification, chained parameters were included, as below:

2.21.1.4.13 Chained parameters 

In order to save a client from performing a series of search operations, reference parameters may be "chained" by appending them with a period (.) followed by the name of a search parameter defined for the target resource. This can be done recursively, following a logical path through a graph of related resources, separated by .

Hello;

I have created an App launch to my FHIR app in the sandbox and am able to access Patients that are provided in the Sandbox. Having done this, I would now like to upload a  test patient in a FHIR bundle to the sandbox, however I have not been able to find out how I can do this.

Can you provide some direction/tools that I can use to upload my bundle to the sandbox?

Thanks

Is there any simple code in Cache using FHIR to understand the relationship between them? If so can anyone provide some example.

I want to install a new FHIR server from the Management Portal using the below steps, but not able to find FHIR Configuration setting under my newly created foundation namespace. 

1. Open the Management Portal and switch to the Foundation namespace where you want the FHIR server installed. If you do not have a Foundation namespace, go to Health, and select Installer Wizard from the top menu bar. The Configure Foundation button allows you to create a new Foundation namespace. Be sure to activate the namespace after creating it. Done
2. Navigate to Health > MyNamespace > FHIR Configuration.

I am receiving a FHIR bundle and I need to extract data from it and wondered if there was an easier way of doing this rather than looping through the data as suggested in Working with FHIR Data | FHIR Support in InterSystems Products | InterSystems IRIS for Health 2023.2.

Ideally it would be great if there was a DTL the accept STU3 and then extract the data from there and I did try using the HS.FHIR.DTL.vSTU3.Model.Resource.Bundle class (depreciated) but that only allowed me to see the data at the bundle level and not the resources within it (entry).

Hi folks!

Examining FHIR profile validation with InterSystems FHIR server. FHIR profiles is a very useful feature of FHIR standard that helps an organization or solution to establish constraints to a very disperse FHIR standards that are relevant to a particular business solution. Learn more on FHIR profiles.

I created a very simple FHIR profile with the following JSON:

{

"resourceType": "StructureDefinition",

"url": "http://example.org/fhir/StructureDefinition/TutorialPatient",

"name": "TutorialPatient",

"status": "draft",

"fhirVersion": "4.0.

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.

I am de-serialzing a FHIR Resource CodeSystem in STU3 FHIR resources from JSON in my Business Process using the following code:

set pCodeSystemResource = ##class(HS.FHIR.vSTU3.Model.Resource.CodeSystem).%New()
set tStream = ##class(HS.SDA3.QuickStream).%OpenId(pFHIRRequest.QuickStreamId)
if $IsObject(tStream) {
    set tSC = ##class(HS.FHIR.Utils).FHIRToHSFHIR(pFHIRRequest.ContentType, tStream, .pCodeSystemResource, "HS.FHIR.vSTU3.Model.

I've been trying to interoperate with careevoltion using their backend-services.

This involves creating a JWT (JSON Web Token) that I have been unable to do using %OAuth2.JWT:ObjectToJWT.

I downloaded jwt.pfx and then ran the following openssl commands to create some pem files.

openssl pkcs12 -in jwt.pfx -out file.nokey.pem -nokeys
openssl pkcs12 -in jwt.pfx -out file.withkey.pem

openssl rsa -in file.withkey.pem -out file.key

Hi, what is the easiest way to clear all the tables which store FHIR data? The most straitforward approach is to get a list of tables using the information_schema.tables view, then execute dynamic SQL with the "delete from" clause, but perhaps some helper class has already been written for this purpose?
