Overview
ISO/TS 23030:2020 - Traditional Chinese medicine - Clinical document specification for prescription of traditional Chinese medicine decoction pieces - provides an entry-level implementation template for encoding prescriptions of TCM decoction pieces using HL7 CDA® Release 2.0 (ISO/HL7 27932). The technical specification focuses on the core medication-administration data for decoction-piece prescriptions to support consistent data collection, transmission, storage and exchange in electronic health records (EHRs). It does not prescribe detailed clinical document headers or unrelated body sections.
Key topics and technical requirements
- CDA-based entry templates: The specification reuses HL7 CDA Release 2.0’s substanceAdministration template as the basis for the medication-administration section.
- Defined elements and cardinality: Detailed elements (e.g., effectiveTime, routeCode, doseQuantity, consumable/manufacturedProduct) and cardinality constraints are specified, with CONF-nnnn conformance statements (CONF-0001 … CONF-0028) that implementers must follow.
- Template identifiers and OIDs: Required templateId roots are specified (for example, 2.16.840.1.113883.2.23.11.5.1.1 and 2.16.840.1.113883.2.23.11.5.1.2) to ensure consistent document recognition.
- Terminology and code systems:
- Route and site codes may use SNOMED-CT (code system OID 2.16.840.1.113883.6.96).
- Decoction method and decoction service use dedicated code system OIDs referenced in the spec (e.g., 2.16.840.1.113883.2.23.11.5.2.1 and …5.2.2).
- Structured decoction data: Templates cover decoction-piece names, dose instructions, special decoction methods, frequency (PIVL_TS), execution interval (IVL_TS), and package counts.
- Annexes: Annex A contains value sets; Annex B provides an XML example demonstrating the template in CDA XML.
Applications and who should use it
This TS is practical for:
- EHR and clinical systems vendors implementing TCM prescription modules.
- Health IT architects and integration engineers building CDA-based interoperability for TCM.
- Hospitals, TCM clinics and pharmacies exchanging electronic decoction-piece prescriptions.
- National/regional health authorities and standards committees integrating TCM prescribing into health information exchanges.
- Clinical informaticians who need consistent semantics for medication administration, CDS, reimbursement, audit and reporting.
Practical benefits include improved interoperability, reduced transcription errors, standardized data for analytics and decision support, and consistent encoding of decoction methods and services.
