CDA Templates

•  Analyst, modeler, “templater” •  definitions of items for messages/documents

based on data set / scenario •  Links to

•  The right value sets •  The right message/document

specification (template) •  Representing concepts with HL7 v3 templates

ART-‐DECOR: tasks + definitions

Template element element

Overview

templater templater

templater

terminologist

•  Re-‐usable blocks •  Semantics clear •  Use in many contexts (scenarios) with link to

concepts and terminologies •  Make specification and implementation of

messages / documents “much easier”

Advantages of “templates”

•  Structure of the CDA-‐Document •  Section: List of all

Vaccinations (human)

•  Entries with Medication Information (computer)

“Vaccination Certificate”

Header structured and coded

Body structured content with coded „sections“

Section: Vaccinations • code • titel • text (list)

Vaccine#1

Vaccine#2

...with CDA you aren‘t there yet...

Generic models

...need something

...to fill the gap

...to semantic interoperability

•  A template is a set of further constraints on top of an underlying model

•  Example: patient •  Model: the patient shall have

one or more identifications (id) •  Template: our patients shall have exactly one NHS

patient identifier

•  Documentation of “rules” in HL7’s Templates Exchange Format (DSTU)

HL7 / CDA Templates

Patient id: II 1..1 addr: AD 0..* telecom: TEL 0..*

•  Template Viewer based on the Templates DSTU R1 exchange format

•  Documentation of templates in ART, as HTML or PDF

•  Two Template editors for HL7v3 / CDA Templates

•  Terminology Browser for various terminologies •  Already seen: Value Set Editor

Features of ART-‐DECOR for HL7 / CDA Templates (1)

•  Building Block Repositories with various “standard” templates and value sets, e.g. C-‐CDA R 1.1 (2.0 to come), CCD 1, epSOS, IHE

•  ISO schematron generator, works with open and closed templates

•  RESTful services to get various artifacts •  Under investigation: FHIR profile and value sets

import/export functions and profile editor

Features of ART-‐DECOR for HL7 / CDA Templates (2)

ART-‐DECOR templates

•  Template Viewer Nagivation

•  Also •  Refresh •  New Link to a Template in

a Repository (later) •  New Template •  Hide Navigation Bar

FHIR with ART-‐DECOR

•  FHIR (Fast Healthcare Interoperable Resources, pronounced “fire”)

•  HL7‘s next generation standard (mobile appilcations)

•  ART-‐DECOR strategy •  FHIR Terminology Capabilities •  FHIR Profile (and Resource) Viewer •  FHIR Profile Editor under investigation

ART-‐DECOR FHIR strategy

•  End goals: •  Integrate writing and retrieving FHIR Profiles and

ValueSets on par with DECOR Templates and Value Sets are today;

•  Provide the same level of validation and testing as currently available for V3.

•  First connectathons in Feb 2015 (Terminology) and May 2015 @ Paris WGM

ART-‐DECOR FHIR Strategy

Alexander Henket Nictiz, The Netherlands

henket@nictiz.nl

•  Current state of affairs on server •  REST API implementation almost done; •  Based on 0.4.0.3886 (Dec 12, 2014)

•  Next steps (2015-‐2016) •  Automate code generation where possible •  Update Value Set Editor •  Work on Profile Editor •  Update for DSTU2

ART-‐DECOR FHIR Strategy

ART-‐DECOR is developed with funding by

•  Nictiz, Den Haag (NL)

and •  Heitmann Consulting and

Services, Hürth (DE) •  Gerrit Boers, Maastricht (NL) •  HL7 Germany, Köln (DE)
