Fast Healthcare Interoperability Resources (FHIR, pronounced "fire") is a draft standard describing data formats and elements (known as "resources") and an application programming interface (API) for exchanging electronic health records
I have MacBook Pro M3 and I'm new to the IRIS for Health setup / installation with all pre-requisite / requirements so someone could please help me with detailed instructions on how to setup IRIS for Health (HL7 & FHIR) from scratch along with SQL Server? I have Windows 11 installed in parallel desktop if that's required and complete installation / setup is not possible on MacBook.
Everytime I try to send a POST FHIR bundle I'm getting the following response: 404 Not Found. I'm not really sure why, although it works fine with a GET!
This is an example:
Response:
It might be something related to request path but not really sure.
I'm attempting to build a fairly complicated object graph, with nested objects and collections, in order to create a FHIR bundle.
In its most basic form there is a <bundle></bundle> element that represents the root, and there can be a number of nested <entry></entry> child elements.
I'm trying to customize error handling in the overriden HS.FHIRServer.Storage.JsonAdvSQL.Interactions::Search method. It is clear how to add to the resultset a valid FHIR resource (pseudocode):
I am trying to work with Epic on FHIR. Epic's documentation stated, your application makes a HTTP POST request to the authorization server's OAuth 2.0 token endpoint to obtain access token.
Set tSC = ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient(pClient,pScopes,.prop,.err) returns
ERROR #9761: No key in provided JWKS for alg ES512 and kid
I check this /csp/sys/oauth2/OAuth2.JWTServer.cls?client_name=medbank and I see this:
My IRIS instance is connected to a Postgres database using SQL Gateway and linked tables.
One of these tables is projected to the Patient class. I want to select a record from this table by ID and convert it to a FHIR resource using the %ExistsId and %OpenId methods.
I noticed that if I call these two methods from the console, the record is always found.
I finally figured out how to get JWT token using set x = ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient("medbank","openid fhirUser",.prop,.err).
I also found iris-fhir-client app on Open Exchange. I registered Epic sandbox server, but I cannot list resources. I suspect I need to integrate authorization / authentication. How do I do this with irisfhirclient py?
I'm playing with some anayltic queries against FHIR server tables. The HSFHIR_X0002_S_Patient.addressCity table contains a lot of cities which names contain german charachers such as ä, ö and ü.
The following query works fine:
select value from HSFHIR_X0002_S_Patient.addressCity
But this one converts city names to uppercase, and characters with umlauts are lost, so instead of "Köln" or "München" I see KOLN and MUNCHEN:
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.
We are going to have basic patient demographic data coming in to Cache via a webservice. I thought that I should define the input as XML something like the FHIR format (with UK extensions).
In the past we've input XML streams and used the %XML.Reader to convert them to matching classes successfully, so I thought it would be easy. However, I've found that the FHIR format stores everything in attributes like:
I am trying to use IRIS for Health as a Facade for an external FHIR Server, where IRIS provides the proper authentication.
The client authenticates using a bearer token obtained from the IRIS OAuth2 server via a jwt client assertion.
The IRIS endpoint, however, returns a 401 as soon as I remove the Unauthenticated access
Is there w way to make this work through configuration?
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:
I am still trying to understand and come up with a use case to use FHIR as an enhancement to our existing HL7 messages. Does anyone have an example of taking a FHIR response and transforming it into a SDA?
How does the workflow go? Does it go through 1 BP?
I am trying to create a HS.FHIR.DTL.vR4.Model.Resource.Encounter message based on a conversion of HS.FHIRServer.Interop.Response QuickStream to a JSON %Dynamic Object.
When I try to send the HS.FHIR.DTL.vR4.Model.Resource.Encounter onto the Router
I have this response, which is a FHIR location resource in a bundle. I would like to load the entry(0).resource into a context property defined as HS.FHIR.DTL.vR4.Model.Resource.Location so I can use it as a source in a DTL. Any help would be greatly appreciated. Thanks.
I was looking for an easier way to build the FHIR Query String, given the Record Map request that is passed into the DTL.
I built this Function, but when I run a message through it, my Query String that is passed back into the DTL is a Reference Pointer and not the String I am looking for.
I'm trying to complete Inferno Service Base URL test for FHIR endpoint and I thought it wanted host.com/fhir/r4/.well-known/smart-configuration but I get header error below. Am I using the wrong Service Base URL List or am I missing something? I'm running 2021.2 HealthShare
ERROR <HSFHIRErr>InvalidAcceptSpec: No valid Accept data found (Accept header or _format parameter)
I'm unable see the FHIR SQL builder /csp/fhirsql and /csp/fhirsql/api/ui endpoints in web application to access the FHIR SQL builder. I'm using community edition 2024.1 and it contains the "FHIR SQL Builder".
I'm running into an intermittent issue with some of our Custom Operations/Processes as a result of some large FHIR R4 Binaries. Essentially we get a response from an AthenaHealth FHIR endpoint that appears to be too large to be processed using the IRIS Built In Functions for FHIR:
I've replicated it on the command line here using a file (binary.json) that has the response from the FHIR Endpoint. Not sharing full contents due to PHI concerns.
Using the FHIR DEMO, I have pieced together how to make a FHIR Request using OAuth against an External FHIR Repository. When I execute the Patient search (HS.FHIRServer.Interop.Request), I get a HS.FHIRServer.Interop.Response that has a Quick Stream ID, which I then use to convert the Quick Stream to a JSON Dynamic Object. if I do a trace on the Raw JSON Object, I am able to pull out single elements, however I want to pull the raw JSON into a defined Class Structure.
I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry. Here's the Output it displays on HTML page:
IRIS for UNIX (Red Hat Enterprise Linux 8 for x86-64) 2024.1 (Build 267_2U) Tue Apr 30 2024 16:06:39 EDT [HealthConnect:7.2.0-1.r1]
I have a use case where Epic is sending an A60 Allergy transaction is set at the Patient level, but we have a system called VIBE which needs the ADT at an Encounter level instead. Currently we store ADT information in a MS SQL database for years, and we are querying it to get the latest Account Number to insert into the ADT^A60 for VIBE.
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.
I have verified that the OAuth works by executing it manually via a Terminal to verify I get a response. Of course, when I do it is writing to the ISCLOG
