Introduction

(This page is under construction and contains information that is still subject to update and correction.) This page describes the tenth FHIR Connectathon that will be held on Saturday Oct. 3 (9am - 5pm++) and the morning (9am - 12.30pm) of Sunday Oct. 4, 2015 in Atlanta, GA prior to the HL7 Working Group Meeting (see http://www.hl7.org/events/wgm102015/).

Location

The meeting will be held at the host hotel, Sheraton Atlanta, Atlanta, GA.

Important notes:


Sunday

Please note lunch is not included for Sunday with the Connectathon registration fee.

Themes

This connectathon will have 6 separate themes

  • Basic patient management
    • The patient resource is well defined, and these scenarios are intended for a user new to FHIR to interact with it at a basic level. it covers:
    • search
    • 'CRUD'
    • history
    • extensions
  • Terminology Services
  • Financial Resources
  • EHR record lifecycle architecture
  • Structured Data Capture
  • Scheduling


Note: at every connectathon, participants attend and test functionality other than that described in the scenarios.

Note also that the connectathon will be based on the DSTU-2 QA version of FHIR which will be posted at [1]

Connectathon Organization

The connectathon will be held over 2 days - the Saturday and Sunday prior to the HL7 Working Group Meeting.

Saturday is a full day, and is intended for participants to test and develop software in an informal way. Test servers will be available (actually, they are already - FHIR Test Servers ), but some participants may bring other servers along depending on the actors they are fulfilling. Sunday is the morning only, and has 2 parts:

  • the formal testing part
  • a mini-showcase where participants can demonstrate their work to the others

Each stream has a coordinator. The nominated coordinator's responsibilities:

  • In the lead up to the connectathon: track participants, respond to queries about scenarios, connect participants to each other
  • During the connectathon act as a test mediator / progress tracker
  • track emergent issues that should be fed back to the committees

Enrollment

If you or your company are interested in participating in the connectathon, please do the following.

  • Read the FHIR Specification and the FHIR wiki if you haven't already done so, to become familiar with the concepts.
  • Read the scenario descriptions below.
  • Register to attend the WGM, and make sure to select the Connectathon option when you do
  • Optionally add your details below (in the 'Registered Participants' section) to indicate the scenarios you intend to participate in

Space at the venue is limited, so please register as soon as possible. Preference will be given to those who are actually participating in the technical event, but observers are welcome if space permits.

Connectathon tracks

This section lists the scenarios that are proposed for this connectathon. More detail will be added when approved. The scenarios are grouped into 3 tracks. Track 1 is for those new to FHIR and requires minimal preparation in advance of the connectathon (at least for client applications). Tracks 2 and 3 are focused on particular implementation activities with FHIR and exercise a more complete set of behavior designed to reflect a full production experience - preparation in advance will be required.

Note that this track - as with all tracks - will use the candidate 'DSTU-2' version of FHIR as described here. If you've been to a connectathon before and done this track, then you may need to change your code, as there have been many important changes to the specification.

Track 1 - Patient

Coordinator: David Hay

If creating a client, this track should require minimal work in advance of the connectathon, though at least a bit of playing is recommended. If creating a server, advanced preparation will be required, but this scenario should somewhat limit the effort involved.

Pre-requisites: none


1. Register a new patient

  • Action: (Patient Demographics consumer) creates a new patient and save to Patient Service. The client can assign the Id.
  • Precondition: Patient does not exist in service prior to action
  • Success Criteria: Patient created correctly on server (use browser to inspect Patient)
  • Bonus point: The Patient resource has an extension

>>Note: the requirement for the client to assign the Id has been relaxed. However, if the server assigns the Id, then the client will need to be able to retrieve the Id from the server response or by a patient query.

2. Update a patient

  • Action: (Patient Demographics consumer) updates the patient created in scenario #1 and updates to Patient Service. The patient is retrieved by Id.
  • Precondition: Patient has been created
  • Success Criteria: Patient updated on server (use browser to inspect Patient)
  • Bonus Point #1: Update a patient that has extensions, but leaving the extension untouched.
  • Bonus Point #2: Update a patient that has extensions, and update the extension also.

3. Retrieve Patient history

  • Action: (Patient Demographics consumer) searches the patient Service for the history of a Patient
  • Precondition: There is a patient that has at least one update
  • Success Criteria: Patient's history displayed in interface. (use browser query Patient Service)
  • Bonus point: The UI allows the user to display previous versions of the Patient

4. Search for a patient on name

  • Action: (Patient Demographics consumer) searches the patient Service for patients with a given name
  • Precondition: Patients with that name have been created
  • Success Criteria: patients displayed in interface. (use browser query to confirm)

Track 2 - Terminology Services

Coordinator: Rob Hausam (There is a dedicated skype chat for terminology services - Contact Rob to be included - skype id rhausam)

Service Providers

For service providers, implement the following operations from http://hl7.org/fhir/2015May/terminology-service.html:

  • $expand
  • $validate-code (note: there's a set of typos on the terminology service page where this operation is called "validate" but its actually "validate-code" - editorial oversight)
  • $lookup
  • $translate (note: there's a typo on the terminology service page where the example has '$validate' not '$translate')

Service providers are not required to implement all this functionality - it's a lot to do. For new implementers, start at the top and work down (generally)

(note for participants in the first terminology services connectathon: this stream builds on the previous connectathon by adding $lookup and $translate)

There's a fairly specific test script with detail descriptions of scenarios at http://gforge.hl7.org/svn/fhir/trunk/connectathons/Paris2015/tx_test_script.xml (for anonymous access, use 'anonymous' with our email as a password). Implementers are not required to implement the full script and pass those particular tests, though it is encouraged to be able to do so

note about the test script: you need a version of Sprinkler to execute it (details to be provided). It looks like a resource, and there is a proposal to actually add it as a resource. On the other hand, we'll be considering alternative proposals in Paris as well as that format. Or you can use any other kind of http based test service; there's nothing magic there.

Client Consumers

Any one of

  • do a value set expansion of one of the value sets in the spec
  • validate a code using the spec against a FHIR value set, a v2 value set, or LOINC or snomed CT
  • look up a display for a code (most appropriate for v2/FHIR conversion)

At least one server supports all these operations (http://fhir-dev.healthintersections.com.au). Other servers, including the Apelon server (http://fhir.ext.apelon.com:8081/DtsOnFhirDemo) will support some of those operations


Track 3 - Financial Management

Coordinator: Paul Knapp

The details of this track can be found here: Connectathon9_Financial.

In summary the test scenarios are:

  1. Submit a Claim via REST (Create), Retrieve a ClaimResponse (Get)
  2. Submit a Claim via WSI Web Services and Receive a ClaimResponse
  3. Retrieve deferred ClaimResponse via ProcessRequest


Track 4 -EHR record lifecycle architecture

Coordinator: Gary Dickinson

An EHR, PHR or other trusted system manages record entries, most often as persistent evidence of patient health and provision of healthcare services. When FHIR is implemented natively, record entries may contain one or more resources.

Record entries have a lifespan (period of retention) often based on legal, regulatory and/or policy requirements. During the record entry lifespan, one or more record lifecycle events may occur. For purposes of this Connectathon, focus will be on resource creation(C), update(U) and read(R). See the FHIR Record Lifecycle Event Implementation Guide (DSTU-2) for additional details: http://hl7.org/fhir/ehrsrle/ehrsrle.html

FHIR AuditEvent and Provenance resources are designed to capture vital authenticity and accountability metadata. For this Track, it is recommended to:

  • Create AuditEvent resource (AuditEvent.object.reference) at each lifecycle event when resource content is created(C), updated(U) or read(R).
  • Create AuditEvent resource (AuditEvent.object.reference) for other events, such as query, transmit/submit/send, receive/retrieve.
  • Create Provenance resource (Provenance.target) at each lifecycle event when resource content is created(C) or updated(U).

Track 4 has no scenarios of its own instead it adds applicable accountability and authenticity metadata (via FHIR AuditEvent and Provenance) to resources in other Track scenarios.

Publicly Available FHIR Servers for testing

Should I come only for the Connectathon?

Coming for the connectathon alone has value - many implementers have attended just for the Saturday/Sunday and been happy. However, if you're already on-site, there's a lot of other FHIR-related activities to participate in that may further increase your return on investment (see the list of tutorials at the bottom of this page)

FHIR User Group

Subsequent to the actual connectathon (i.e. Sunday PM) the "Application Implementation and Design (AID)" HL7 User Group will meet to discuss FHIR implementation approaches and design patterns. You're invited to share your 'lessons learned' with others in the FHIR implementation community, or to listen to other FHIR implementers.

  • See AID Sunday PM Agenda for details.
  • Please contact Rene Spronk to get hold of a slot on the AID agenda - we do appreciate you sharing your ideas and experiences.

FHIR Tutorials

There are 4 tutorials scheduled through-out the week

  • Mon pm - Introduction to FHIR
  • Tue am - FHIR for Architects
  • Tue pm - FHIR for Specifiers
  • Wed am - Intro to FHIR Development

Detailed descriptions are available in the WGM brochure

Working Group session

HL7 WGMs are where a lot of the development work on FHIR happens. Numerous work groups will be considering FHIR change proposals, working on FHIR profiles and resources and debating other aspects of FHIR implementation. As well, there will be meetings of the FHIR Governance Board and FHIR Management Group discussing policies relating to FHIR. There are often ad-hoc meetings at breakfast, lunch and after-hours to discuss items of interest such as tooling, new domains, particular technical issues, etc.

The final agenda won't be determined until very close to the meeting (and will evolve somewhat throughout the course of the week), however you can take a look at the [[2]] from the May WGM to get a sense of the breadth of discussions that will be taking place. FHIR runs full bore from Monday to Friday (capping off with the clinical connectathon on Friday), so regardless of what days you're present, there will likely be something of interest.

Participating in the WGM is a good way to get a sense of the people involved in building the spec, to form relationships, to get more deeply involved in the FHIR community and to influence how the standard evolves.
