Topic: R5 Appointment.note in FHIR 4.0.1

view this post on Zulip Samuel Brendler (Feb 24 2022 at 10:07):

Hello everyone,

I am looking for a way to implement comments for Appointments in FHIR 4.0.1.with a 0..* relationship instead of 0..1 and also need additional data about each comment's author and a timestamp.
I discovered that R5 already is supposed to provide exactly what I want with the Appointment.note 0..* Annotation
(see https://hl7.org/fhir/5.0.0-snapshot1/appointment.html, https://jira.hl7.org/browse/FHIR-19521).

Are there any best practices doing this in FHIR 4.0.1 or even an existing extension?
Any hints on how to implement this correctly with fsh are much appreciated!

Best regards

There are guidelines for using a 'standard' extension URL to adopt data elements defined in a different version of FHIR - see http://build.fhir.org/versions.html#extensions

Thanks a lot for the response!

I added the following to my sushi-config.yaml 

dependencies:
  hl7.fhir.extensions.r5: 4.0.1

and changed MyCustomAppointment:

Profile:        MyCustomAppointment
Parent:         Appointment
Id:             my-custom-appointment
Title:          "My Custom Appointment Profile"
Description:    "My Custom Profile for appointment data."

* extension contains http://hl7.org/fhir/5.0/StructureDefinition/extension-Appointment.note named note 0..1

Running sushi . reports no errors or warnings, but when I try to generate the IG with ./_genonce.sh I receive the following error:

Is this due to R5 not yet being released?

I also tried with a snapshot URL but sushi didn't like that:
* extension contains http://hl7.org/fhir/5.0.0-snapshot1/StructureDefinition/extension-Appointment.note named note 0..1

no that should work - how can I reproduce?

Thanks for the responses @Grahame Grieve @Lloyd McKenzie

I created a simple example based on a vanilla sushi project on github where you can try it yourself.

Steps to reproduce (on Linux):

git clone https://github.com/iroCheese/demo-fhir-appointment-profile.git
cd demo-fhir-appointment-profile
./_updatePublisher.sh
./_genonce.sh

The relevant changes are in this commit.
