HL7 FHIR® Implementation Guide: CodeX Radiation Therapy Treatment Data, Edition 2 - US Realm

DESCRIPTION

There is a demonstrated need to establish data standardization for RT end-of-treatment summaries, in-progress summaries, and supporting clinical details to supplement these summary reports. The CodeX Radiation Therapy (CodeX RT) Implementation Guide (IG) describes how to represent, model, and exchange RT information that is generated during a patient’s RT planning and treatment. This FHIR IG is intended for health information system implementers interested in sending or receiving RT information. The CodeX RT IG provides nine profiles based on FHIR ServiceRequest and Procedure resources, and one based on the FHIR BodyStructure resource.

See the specification at http://hl7.org/fhir/us/codex-radiation-therapy/STU2.

ALTERNATIVE NAMES

HL7 FHIR® Implementation Guide: CodeX Radiation Therapy Treatment Data, Edition 2 - US Realm may also go by the following names or acronyms:

"HL7 FHIR® IG: CodeX Radiation Therapy Treatment Data (RTTD), R1",,RTTD

BENEFITS

The RT IG supports radiotherapy clinical workflow by:

  • Enabling RT prescriptions at the course, phase, and plan levels
  • Facilitating development and management of the Planned Course, Planned Phase, and Treatment Plan
  • Generating a Course Summary, Treated Phase and Treated Plan after care is delivered

Once structured data is captured during the care process, that data can be made available for data sharing and reuse. The CodeX RT IG leverages FHIR and FHIR Application Programming Interfaces (APIs) to promote interoperable exchange of RT information between an ROIS and other health information systems such as an electronic health record (EHR). The CodeX RT IG has defined radiotherapy FHIR profiles for vendors to implement in their systems and share, via FHIR API, with other FHIR-enabled radiation oncology information systems or EHRs.

IMPLEMENTATIONS/CASE STUDIES

Case Study #1: A radiation oncologist generates a patient’s RT “end-of-treatment” summary within the ROIS after treatment is complete. The patient’s summary information is pushed, via a FHIR API, to a receiving FHIR repository (e.g., a cloud-based repository or another repository that can be accessed by other vendors). Next, a vendor system accesses the FHIR repository via a FHIR API call to retrieve the patient’s RT “end-of-treatment” information. Once the information has been retrieved, the vendor system can store, share, reuse, and display the standardized information however necessary/most useful.

Case Study #2: A radiation oncologist generates a patient’s weekly on-treatment visit (OTV) report within the ROIS. The patient’s weekly RT in-progress information is pushed, via a FHIR API, to an EHR’s FHIR-enabled internal resource repository. Next, the EHR accesses its internal FHIR repository via a FHIR API call and retrieves the patient’s weekly RT in-progress information. Once the information has been retrieved, the EHR can store, share, reuse, and display the standardized information however necessary/most useful.

 Implementations by radiotherapy vendors:

  • Varian,
  • Raysearch.

Implementations by HIS vendor: Epic.

Used as base profile for IHE-RO integration Exchange of Radiotherapy Summaries (XRTS) profile, Trial Implementation STU1.1 and upcoming STU2 by same vendors.

DEVELOPMENT BACKGROUND

The Codex RT IG builds on the minimal Common Oncology Data Elements (mCODE) Standard for Trial Use 4 (STU 4). For a full description of how this IG leverages mCODE profiles and value sets is provided in the Building on mCODE section (http://build.fhir.org/ig/HL7/codex-radiation-therapy/branches/master/building_on_mcode.html).

The mCODE STU 4 IG also includes a Radiotherapy Glossary that contains all key terms, their definitions, and related examples. The remaining radiotherapy concepts are defined in this IG.
