Overview
ISO/TS 5499:2024 - "Health informatics - Clinical particulars - Core principles for the harmonization of therapeutic indications terms and identifiers" - defines common principles for creating, assessing, selecting and maintaining maps between terminological resources used to describe and code therapeutic indications under the IDMP (Identification of Medicinal Products) data model. The Technical Specification addresses terminologies, use cases and core maintenance principles (reliability, reproducibility, quality assurance) needed to harmonize indication terms and identifiers for medicinal products, biologics, medical devices, combination products and companion diagnostics.
Key topics and requirements
- Terminology coverage: Guidance for common clinical terminologies used for indication coding, including SNOMED CT, MedDRA, ICD, MeSH and drug classification systems (e.g., ATC).
- Use-case driven mapping: Mandates that maps be developed and validated against explicit use cases (e.g., regulatory submission, clinical trials, pharmacovigilance), because semantic tolerances differ by purpose.
- Mapping prerequisites and processes: Defines required processes and best-practice conventions for building maps between terminologies, including handling of national/regional terms and hierarchy differences.
- Quality and maintenance principles: Emphasizes map reliability, reproducibility and quality assurance, with ongoing governance and stakeholder engagement for map updates.
- Safety considerations: Highlights that semantic shifts acceptable for aggregation (statistics, billing) may be unacceptable for patient-level clinical care - maps must reflect this distinction.
- Stakeholder engagement: Encourages involvement of regulators, clinicians, industry and implementers from project inception through maintenance.
Applications and who uses this standard
ISO/TS 5499:2024 supports implementation and interoperability where coded therapeutic indications are needed:
- Global regulators and health authorities for consistent IDMP data exchange and coded labelling.
- Pharmaceutical / biopharmaceutical companies and CROs for clinical trials, regulatory submissions and product labelling.
- Healthcare providers and EHR implementers to improve recording of medication indications and support safe prescribing.
- Pharmacovigilance teams to link adverse event monitoring with therapeutic uses.
- Standards organizations and software vendors building terminology map sets and clinical decision support.
- Researchers and registries requiring harmonized indication data across datasets.
- Patients and public health stakeholders benefiting indirectly from clearer, comparable safety and efficacy information.
