About

Welcome to the Canadian FHIR implementation community forum. The purpose of this forum is to collaborate on areas of FHIR implementation that will advance implementations across Canada, while contributing to the global adoption of FHIR. The objective is to develop pan-Canadian approaches to constraining and extending FHIR. The community has been active since January 2016 and has been growing ever since!

The community currently has three streams of activity:
1. Topical workstreams
2. Monthly community calls to share workstream progress and other FHIR-related news
3. A general forum to ask questions and share information

The table below provides more details on the workstream activity:

Attila Farkas created a new discussion in FHIR® Implementations
Hi everyone, I am creating a new thread for the FHIR Registry where we can list the enhancements that are implemented to the Simplifier.NET platform that is powering our registry. These updates are coming on a monthly basis so knowing about them can help you work smarter. Here are the highlights for the January release 17.7: Implementation Guide Editor The new IG Editor includes two new features. You can now export your IG to static HTML pages, which can be hosted anywhere. This is useful when publishing milestones and to comply with organizational publishing policies. The IG Editor's intellisense feature displays projects and resources on Simplifier.net on the fly. Diff Viewer The Diff Viewer 2.0 displays differences between two versions of a resource. Go to the history tab of a resource, select two versions and click the compare button to see the renewed Diff Viewer in action. Validate We added a new way to validate your profiles and instances. Next to validating snippets or resources in your project, you can use the validator without needing to log in or upload resources. Copy and paste FHIR content here. The Profiling Academy We added a terminology module to the Profiling Academy, the free online learning platform on FHIR profiling. Includes exercises.

Enhanced browsing of HL7 v3

Infoway HL7 Explorer is a powerful browser for HL7 v3 structures, vocabulary and references. Used in conjunction with the pan-Canadian releases, HL7 Explorer makes locating details and information more efficient.

In November 2017, the Canadian HL7 InfoCentral community determined that there was no longer any need to do further updates to the pan-Canadian Version 3 messages. As a result, the December 2012 releases of MR02.06.01 and CeRx 4.4.2 are the latest pan-Canadian publications of these standardized messages.

The HL7 Explorer, the Master Terminology Worksheet (MTW) and all other messaging related artifacts are aligned with the latest releases.

infoscribeSupporting the Standards Selection Framework, InfoScribe enables teams to collaboratively create, discuss, and publish digital health solutions from clinical requirements to specifications. Featuring templates, versioning, PDF export, inline commenting and HL7 Explorer integration, InfoScribe improves productivity and accelerates the development of healthcare solutions.

Standards Selection Framework

The Standards Selection Framework provides users with the means to plan, choose and document interoperability solutions from concept through to implementation. Starting from the Clinical Requirements identified by clinicians through to business requirements, standards and technical specifications, the framework provides a comprehensive guide through the development of interoperability solutions.

The framework also provides an opportunity for the InfoCentral community to share successful implementation projects, the standards selections made at a point in time of the project and the specifications that result from the selections made. Publishing solutions in this space will help to establish a Canadian repository of references.

clinical requirements

Clinical Requirements describe the information and workflow needs of the clinician for a specific clinical context and clinical data exchange. Using the Clinical Interoperability Principles as a guide, a set of requirements expressed in the clinician’s voice will provide the foundation for a well-designed interoperability solution.

business requirements

Business Requirements are derived from clinical requirements and provide a full picture of the solution that needs to be developed. Use cases, business rules and guidance are used to fully outline the solution design.

standards selection

Standards Selection refers to the process that has been developed to help guide teams through the selection of terminology and messaging standards. Using the line of inquiry and considerations in the forms provided implementation teams may assess the standards available and determine the best option for the point in time. The process also provides an opportunity for the InfoCentral community to share successful implementation projects, promoting standardization through reuse.

standards

Standards are an integral piece of the interoperability solution, covering both the terminology that defines the data sent, and the messaging structures that define how the data is transferred. The framework provides the access and consideration criteria to the international and Canadian standards to facilitate implementation.

specifications

Specifications provide the details for the solution to be implemented. These details include: a review of the data elements used, samples of transferred messages, the system architecture as well as the security specifications including authorization and authentication.

Solution for API integration

Infoway Message Builder allows developers to focus on the business challenges of integrating their solutions with each electronic health record implementation by abstracting the differences between different versions of pan-Canadian HL7 messaging and supporting current implementation constraints. Developers can build interfaces in a familiar development environment, using the programming language of their choice*, while the Message Builder API fosters quick and easy creation, population and access to HL7v3 requests and responses.

Infoway Message Builder v2.0 and later is enhanced to generate JAVA APIs to create, validate, marshal/unmarshal CDA documents.

 Implementation and Exchange

 

Key features and benefits

Message Builder offers a number of key features and benefits:

  1. Abstracts the complexity of HL7v3 messages and greatly simplifies the work of the developer when implementing them;
  2. Reduces the impact on developers from implementation variations;
  3. Enables companies to achieve Infoway product certification with greater confidence and reduced time;
  4. Enables developers to incorporate future message versions without re-writing their products;
  5. Can be embedded in software applications due to its open source distribution under a commercial-friendly Apache 2.0 license.

Out of the box support

Infoway Message Builder comes with built-in runtime APIs that support a number of pan-Canadian specifications:

  • MR2009 (R02.04.02)
  • MR2007 (V02R02)
  • MR 2007 (V02R01)
  • CeRx (V01R04.3)

In addition, while developers can easily build custom transport mechanisms without affecting the core, Message Builder includes native support for SOAP and RESTful message transports. Developers can configure and extend the transport as desired.

Detailed product features

  • Provides the capability to configure and populate message values that are common to all messages—this allows developers to reuse common message data, shortening the time to configure and create an interoperable system.
  • Uses simplified data types that are natural and familiar to the programming language (e.g. String for ST) rather than directly exposing the sometimes complicated HL7v3 data types—yet still allowing access to HL7v3 data types when necessary.
  • Allows developers to focus on the business-aspect of a request/response, avoiding many of the complexities of HL7v3.
  • Code-generation algorithms merge identical and similar classes together to simplify the generated API—meaning less confusion in the resulting code and an increased ability to write generic handlers for certain types.
  • Converts populated objects into HL7v3 XML requests, and converts HL7v3 responses into populated objects.
  • Provides flexibility in configuring and performing terminology-code lookups, including code set and database-backed lookups (can mix and match).
  • Associations and attributes are strongly typed, given business names when provided, and contain code docs directly from the MIFs (see wiki.hl7.org/index.php?title=MIF).
  • The algorithms inline most classes that only have a small number of properties, further simplifying the API.
  • Offers both permissive and strict modes—permissive allows many common errors and generates appropriate error comments in the XML or result object.
  • A separate validation tool is provided to test ad-hoc messages—this tool reuses the same validation components that are executed during message marshaling and unmarshalling, ensuring consistent processing of the message whether during processing or during conformance validation.

Forward looking

The power of the Message Builder architecture is in its MIF-based generation of the specification API. With Message Builder, any MIF is supported—whether a future release of the pan-Canadian specifications or a modified (constrained) jurisdiction-specific release of an existing specification. 

 

How it works

Message Builder comprises two parts:

  1. Message Builder Generator—a tool used by Infoway to take input MIFs and create Message Sets for use by Message Builder Runtime;
  2. Message Builder Runtime—an API used by developers to allow their products to support multiple Message Sets without recoding.

Message Builder Generator

Used by Infoway, Message Builder Generator takes MIFs (as the source of truth for standards specifications) and converts them into a series of Java Classes. This is done by first converting the MIFs to an XML Message Set (a simplified representation of the information present in the original MIFs), then generating Java Classes that reference standard Java data types and use business-friendly names. In the process, groups of related elements are flattened and similar message parts are placed into a single class: these steps increase ease of use and reduce the complexity of the resulting Java Classes.

MBG process

Using Message Builder Generator, Infoway is able to create multiple Message Sets, each representing the MIFs used in a single jurisdiction, but all for the same HL7v3 version.

Message Builder Runtime

Message Builder Runtime allows developers to quickly adapt to implementations in multiple Jurisdictions: incoming messages are first examined to determine the corresponding source Message Set, once identified, a series of Java Objects that represent the message are instantiated. Next, the Java Objects are turned into an HL7 message for the HL7 version corresponding to the desired destination Message Set. 

MB process

Using Message Builder Runtime developers can accept messages over the wire and on-the-fly turn them into a different HL7 message version. Given the capability of Message Builder to support future versions of HL7 messages, developers can easily future proof their products with minimal effort.

 

*Developer friendly

The Message Builder libraries are available for Java and Microsoft .NET. In addition, a simplified XML message format is available with REST-based services for managing mapping to/from the simplified form to the target specification XML format.

 

CDA Support

Message Builder CDA API supports the following CDA and data type specifications:

Message Builder provides  JAVA and .NET APIs for CDA document creation, validation, marshalling/unmarshalling of the following CDA document types:

  • Continuity of Care Document (CCD) (Release 1.1)
  • Consultation Notes (Release 1.1)
  • Discharge Summary (Release 1.1)
  • Imaging Integration, and DICOM Diagnostic Imaging Reports (DIR) (Release 1)
  • History and Physical (H&P) (Release 1.1)
  • Operative Note (Release 1.1)
  • Progress Note (Release 1.1)
  • Procedure Note (Release 1)
  • Unstructured Documents (Release 1.1)
  • CDA documents using pan Canadian CDA header template

Clinical applications in JAVA or .NET can use the Message Builder CDA APIs to create, validate or parse above listed types of CDA documents. Potential use cases are document source or document consumer actors in IHE XDS profile, content creator/content consumer in any content module/profile, or report creator/viewer in RIS/PACS/EMR systems.

 Implementation and Exchange

Jurisdictional ReMixes

Pan-Canadian Standards use Object Identifiers (OIDs) to distinguish between objects by assigning a numeric string that enables other systems to understand the unique information that is being shared between various systems.

Canada Health Infoway has an arrangement in place with HL7 International that allows Infoway to submit OIDs to HL7 International on behalf of Canadian Implementers free of charge. There is a $100 USD fee ($250 USD effective January 2018) per OID request if done directly with HL7 International.

To submit an OID, download the registration form that corresponds to your OID request. Email the completed form to This email address is being protected from spambots. You need JavaScript enabled to view it.

Automated notifications of new content in Terminology Gateway

A WebHook is an HTTP callback. When new content is published in the Terminology Gateway, a publishing event will be POSTed to each registered WebHook, notifying their respective owners about the publication.

WebHook registration

Individual users can register for WebHook notifications by sending an email to: This email address is being protected from spambots. You need JavaScript enabled to view it. and specifying the WebHook endpoint. Upon registration, a unique api_id will be assigned to the WebHook. Each notification POSTed by the Terminology Gateway will contain the api_id, allowing the endpoint to verify that the notification was indeed issued by the Terminology Gateway. The api_id must be echoed back by the WebHook endpoint in the body of the notification response.

WebHook interface

The WebHook endpoint must serve HTTP requests conforming to the following interface:

HTTP Request

{
  "api_id": "cb570e5a2748f349f9119431db836b3a23fdb6571afee34c0432d87220f2431b",
  "base_url": "https://termapi.infoway-inforoute.ca/rest/v1/",
  "notification_time": "2017110711:07:00",
  "targets": [
    {
      "id": "2.16.840.1.113883.2.20.6.1",
      "name": "Canadian Clinical Drug Data Set (CCDD)",
      "type": "package",
      "version": "20171016",
      "effective_date": "20171016",
      "publication_time": "2017103015:20:23",
      "message": "Monthly CCDD update for October 2017"
    },
    {
      "id": "2.16.840.1.113883.2.20.3.443",
      "name": "PrescribeIT",
      "type": "package",
      "version": "LPR2",
      "effective_date": "20171103",
      "publication_time": "2017110309:37:22",
      "message": "PrescriptionMedicinalCode version reflecting the October 2017 CCDD update"
    }
  ]
}
				
  • api_id: as previously mentioned, each notification POST contains the api_id granted at registration.
  • base_url: the base URL for the native REST API endpoint of the originating system. This can be used to call back the Terminology Gateway via APIs in order to programmatically download updated content.
  • notification_time: the timestamp of the WebHook notification in yyyyMMddHH:mm:ss format.
  • targets: list of updated targets. Each entry in this array corresponds to a Terminology Gateway artifact (subset, codesystem, map, package) that was updated and is therefore subject to the notification. The target list will only include artifacts for which the user has registered to receive notifications. Users can register to receive notifications about content updates using the Terminology Gateway User Interface or by invoking the native REST APIs.

    Each of the notification targets contains the following fields:
    • id: the artifact id, typically an OID
    • name: the artifact name
    • type: the artifact type: subset, codesystem, package or map
    • version: the published version id
    • effective_date: the effective date associated to the artifact version, in yyyyMMdd format
    • publication_time: the publication time in yyyyMMddHH:mm:ss format
    • message: optional message describing the published artifact version

HTTP Response

HTTP Response code: 200 for success, any other response code will be interpreted as an error
Sample HTTP Response Body:

{
  "api_id": "cb570e5a2748f349f9119431db836b3a23fdb6571afee34c0432d87220f2431b",
  "result": "success",
  "message": "Successful processing of the WebHook notification"
}
  • api_id: as previously mentioned, each notification response must echo back the api_id granted at registration.
  • result: success if the web hook notification was successful, any other value will be interpreted as an error.
  • message: optional response message.


Error handling

When receiving an error as a result of a WebHook notification, the Terminology Gateway will retry the notification four times at 15 minutes intervals. If still unsuccessful after four notification attempts, the system will drop the notification and will notify the user by email that the WebHook couldn't be invoked.

Sample code

Demo code for a sample WebHook endpoint can be found here:
