Case reporting can integrate systems that have different levels of FHIR readiness:

FHIR Naive

Existing tool with limited resources or desire to upgrade to include FHIR support. Have back-end access to database or way to generate tabular reports.

FHIR Aware

Basic FHIR Questionnaire support available for simple data exports from template reports. Can initiate FHIR API calls. Metadata synchronized using IHE profiless (SVCM, mCSD)

FHIR Native

Full FHIR stack, data model and supporting tools are within the system. Can generate robust FHIR resources and data models and metadata has been synchronized using IHE profiles (SVCM, mCSD)

The specification of a case report form comprises two things:

• The specific data fields expected in the case report are defined through the specification of a Questionnaire with a Structured Definition Based Extract as defined in the Structured Data Capture Implementation Guide. The Questionnaire is inteded to ease data collection, particularly from systems with lower FHIR maturity
• A profile of the Composition which will define where the content (e.g. demographic, clinical) of a case report form should reside. This profile also represents the domain of resources onto which a QuestionnaireResponse extracts.
