30 minutes
This is formerly called MERIT-9 document standard, and reported in former HL7 CDA conferences. Now it is HL7 Japan standard by HL7 Japan vote, and is employed in Shizuoka Prefecture EHR project. CDA R2 is used for referral documents and patinet data CD, with pointers to clinical contents (HL7 v2.5 and DICOM). Conforms IHE's XDI (Cross-enterprise Document Interchange). Digital signature methods for the documents conforms W3C recommendation.
HL7 Japan CDA for referral document standard (formerly called MERIT-9, reported in former HL7 IAM and CDA conferences) is a standard for CDA R2 patient referral document, with pointers to prescription and lab result contents (HL7 v2.5) and images (DICOM). It passed HL7 Japan vote as HL7 Japan standard.
Part 1 is for CDA document itself. Part 2 is for its file format in CD. Part 3 and 4 are for digital signature and encryption. HL7J CDA for Referral document conforms W3C recommendation by calculating hash function all with referred contents and put embedded into the document. As it is allowed in IHE’s XDI (Cross-enterprise Document Interchange), HL7J CDA for Referral document conforms XDI.
Use cases for this are not only for patient referral document, but also for handing out patient information in CD. Shizuoka prefecture EHR project employed this standard and already used in real clinical settings. This year, Ministry of Health Labor and Welfare plans a joint project with Shizuoka prefecture to proceed additional development and deploy nationwide. By this, from small clinics to large hospitals, referral documents and patient data handout CD are standardized in CDA R2. The joint project aims to expand its scope of “documents” to disease registrations, surveillance, and clinical trials.
