SMART Guidelines L3 SOP, published by WHO. This guide is not an authorized publication; it is the continuous build for version 1.1.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/WorldHealthOrganization/smart-ig-starter-kit and changes regularly. See the Directory of published versions

Profiles

Profiles are the FHIR representation of the data objects. They include constraints and extensions. Profiles and extensions should be reusable as much as possible, and L3 authors should should aim for reusing reusable profiles/extensions and for creating profiles/extensions that can be reused by others.

Profiles include Element constraints or extensions, and may include constraints:

Inputs

The inputs for creating a profile, extensions and constraints are:

• Data models (DAK)
• Activity to Profile mapping/catalog
• Common Profiles (from commons clinical encounter)
• Common extensions from dependencies

Outputs

• Profiles in input/profiles or input/fsh/profiles
• In Shorthand, constraints should be in the same folder as the profile
• Extension definitions in input/extensions or input/fsh/extensions
• Example instances in input/examples or input/fsh/examples

Activities

Identify profile needs

The FHIR profiles are determined by the need for information objects from the definitions:

• elements,
• decision tables,
• scheduling logic
• processes,
• indicators

The L3 author consults the logical models and the business processes to see which profiles are necessary.

Identify reusable profiles

The L3 Author shall search the common profiles repository to search for profiles that may exist which either

• cover the exchange requirements for the scope
• may be profiled - if they are in a similar or broader area that can be constrained in a derived profile

This search is in related sources - within the the SMART Guidelines ecosystem - or even outside, such as IHE or HL7 or national guidance. In these cases, the L3 author shall apply the necessary validation as the profiles may not meet the expectations or may change without warning.

The recommended priority for the search for existing profiles and extensions:

• other SMART IGs
• HL7 international balloted reference implementation guides
• IHE profiles
• HL7 national balloted reference implementation guides
• other references
• search in previous or upcoming releases of FHIR

Output Criteria / Definition of Done

• One profile per json file / One profile per fsh file, as per naming convention
  • The constraints or invariants applicable to a profile may be contained in the same FSH file.
• All profiles shall be valid profiles
• All data elements that need to be exchanged or used in a decision, workflow, or indicator are covered by one or more profiles.
• Every profile shall have one example instance
• Each StructureDefinition resource SHALL conform to CRMIShareableStructureDefinition
• Each active published StructureDefinition SHALL conform to CRMIPublishableStructureDefinition

Change tracking

As with all FHIR Conformance resources, change management is critical. Do not set the version element of StructureDefinitions defined in the SMART Guideline, the version element will be set by the publication process. See the versioning topic for more information on change management.

In addition, breaking changes to a prior published release should follow a dedicated review process
