The Observation and Diagnostic Report resources have been tested and used in production tooling and as such have reached a maturity level FMM=4 where changes become less likely and require implementer community approval. Future work will focus on developing core profiles and clarifying use cases and boundaries and providing more domain specific examples. We anticipate Observation and Diagnostic Report reaching normative status by the end of this cycle.
The ImagingStudy resource has had some limited testing and use. Further use of this resource in production tooling is needed for it to reach a more stable FMM level.
The ServiceRequest resources has undergone substantial changes since DSTU2. Foremost of which is the merging of DSTU2 DiagnosticOrder and ServiceRequest into a single resource. In addition, as a result of the addition of FHIR workflow for STU3, its structure and content have been updated to align with the general FHIR workflow "request" pattern. Because of these, it remains a relatively immature resource. No more sweeping changes to its structure are expected. However, its scope and boundaries vis a vis other resources will be the topic of future workgroup efforts. We anticipate its broad use by implementers and that it will mature as a resource throughout the upcoming cycle.
The Specimen resource will be the focus of work group efforts for the upcoming cycle. A new SpecimenDefinition resource is planned for describing specimen types vs specimen instances and will take over some of the Specimen resource's current scope. We expect to see more widespread use of this resource and future updates to its FMM level
The MolecularSequence resource remains draft and we expect to see more widespread use of this resource and future updates to its FMM level
The BodyStructure resource is an immature resource with a FMM level of 1. To date there has been little implementation feedback.
The Media resource is the newest member to the Diagnostics module having undergone substantial scope and structural changes to create a specialized observation resource focused on digital media such as images and audio files. Future work will focus on developing core profiles and providing more domain specific examples.
