Mon Q3 - FHIR Core

Chair: Ewout Kramer Scribe: Lloyd McKenzie

Introduction

Ewout Provided a quick overview of the work group, how we meet and the agenda for the week

• 13561 OperationDefinition.parameter is largely redundant with ElementDefinition - Persuasive w/ Mod
• 13376 Settle on a single markdown specification - will solicit feedback on adopting Github markdown spec

Adjourned at 3:07pm

Mon Q4 - FHIR Workflow

Chair: Lloyd McKenzie Scribe: Lloyd McKenzie

Overview

Lloyd provided an overview (File:FHIR Workflow Update 201709.pptx) of the workflow spec, introducing the ideas of workflow patterns and workflow interoperability architectures and briefly described the work that has happened to date.

Pattern changes

Lloyd shared a [[ |presentation]] showing the changes that are being applied to the Event, Request and Definition patterns. The group discussed the difference between "function" codes and "role" codes. There may be a need for function codes in some resources - particularly Procedure. Such resources will be able to still use a nested structure if they need to.

There was discussion of the proposed change to add insurance information to Request. Paul and Lloyd will discuss further before bringing it to the work group for a vote

WorkflowExample

Lloyd provided an overview of the WorkflowExample resource and its purpose and how it would be rendered.

Question about whether the resource could be used to simply show evolution of a resource over time. At the moment, the resource requires identifying sender and receiver

Discussion about changing name of resource. Straw poll conducted. Strong preference for ExampleScenario instead of WorkflowExample as it encompasses the broader scope of the resource

Change Requests

Reviewed [11217]. Discussion about the difference between orders and prescriptions/authorizations. Also discussion about whether DeviceRequest could be exteneded to incorporate VisionPrescription

Outcomes:

• OO will consider changing the "order" intent code (and specializations) to use "authorization" in their names instead. (The actual ordering is a request for fulfillment which is separate from the Request resource.)
• Lloyd will try modeling the Vision resources using an adjusted version of DeviceRequest
• The request resource will be updated to have language about an authorization that defines characteristics of what's wanted vs. an authorization that fully describes what's needed

Wed Q2

Chair: Grahame Grieve Scribe: Ewout Kramer

Item 1 - PSS for II context synchronization

Isaac Vetter runs us through the PSS, which he likes FHIR-I to sponsor. The text of the PSS can be found here. We vote to sponsor, Grahame Grieve/Corey Spears: 21/0/1

Item 2 - Support for data registries in FHIR

Tom informs the group about a usecase in the dutch LSP where a type of Resource is needed that can convey information about what is available in the registry (aspects include type of information, endpoint to retrieve the information, the practitioner involved). Tom suggests a list of canidates but is not convinced any of those are applicable. After some deliberation, we settle on DocumentManifest. Unfortunately, this resource has a required set of references to either a document or resource. This is not applicable to this usecase since there is no reference to actual instances, just information about kinds of information in the registry. Tom will contact SD to talk about relaxing this cardinality. We also suspect that this will lead to a discussion about renaming the resource to e.g. "ContentManifest".

Item 3 - Versioning of endpoints and instances

A continuation of our discussion in Madrid.

Jenny, Kevin and Lenel put forward that some kind of versioning indication seems useful. Agree to have Grahame finish the whitepaper on versioning AND pilot some approaches (amongst which the mime-type based one, akin to GitHub) during the January connectathon. Lots of interest during the meeting. Chris Grenz' blog about this subject highlights another aspect of versioning, that we did not get into.
