Objective: Develop and evaluate a foundational oncology-specific standard for communication and coordination of care throughout the cancer journey, with early-stage breast cancer as the use case.
Materials and Methods: Due to broad uptake of the HL7 Consolidated Clinical Document Architecture (C-CDA) by health information exchanges and large provider organizations, we developed an implementation guide (IG) in congruence with C-CDA. The resultant product was balloted through the HL7 process and subsequently implemented by two groups: the Health Story Project (Health Story) and the Athena Breast Health Network (Athena).
Results: The HL7 Implementation Guide for CDA, Release 2®: Clinical Oncology Treatment Plan and Summary, DSTU Release 1 (eCOTPS) was successfully balloted and published as a Draft Standard for Trial Use in October 2013. Health Story successfully implemented the eCOTPS atHIMSS 2014 in a clinical vignette. During their evaluation and implementation, Athena identified two practical issues: 1) the need for additional CDA templates specific to their use case and 2) the many-to-many mapping of Athena-defined data elements to eCOTPS.
Discussion: Early implementation of eCOTPS has demonstrated successful vendor-agnostictransmission of oncology-specific data. The modularity enabled by the C-CDA framework makes expansion of the eCOTPS to include other cancer subtypes relatively straightforward. Lessons learned during the process will strengthen future versions of the standard.
Conclusion: eCOTPS is the first oncology-specific CDA standard to achieve HL7 DSTU status. Oncology standards will improve care throughout the cancer journey by allowing efficient transmission of reliable, meaningful, and up-to-date clinical data between the many involved stakeholders.
