Overview
ISO/TS 5118:2022 is an ISO Technical Specification in the field of health informatics that defines a unified categorial structure for the evaluation of clinical practice guidelines of Traditional Chinese Medicine (TCMCPG). Rather than addressing guideline development, this document specifies domain constraints and a set of sanctioned characteristics - each expressed as relationships - to standardize how the application and implementation effects of TCM clinical practice guidelines are represented, exchanged and analyzed.
Key Topics
- Categorial structure and semantics: A formal framework for representing evaluation concepts and their relationships to support interoperability and data exchange.
- Semantic links (relationship types): Standardized relationships such as:
- is evaluated of
- is part of
- is manifested of
- is preceded by
- is based on
- according to
- Terms and definitions: Clear, standardized definitions for concepts used in TCMCPG evaluation, including:
- applicability evaluation, consistency evaluation, technical level, structure and contents, coordination and matching, clarity, preciseness, integrity, implementation effect, standardization effect, source evaluation, convenience evaluation, and evidence-based clinical practice guidelines vs expert consensus.
- Scope clarification: Focused on application evaluation and information representation; guideline development methods are explicitly out of scope.
- No normative references: Document contains its own authoritative terms and structure for TCMCPG evaluation.
Applications
- Standardizing how hospitals, research institutions and health informatics systems represent evaluation results of TCM clinical practice guidelines.
- Enabling consistent data exchange and semantic interoperability across databases, registries and evaluation platforms concerned with TCMCPG application.
- Supporting auditors, guideline implementers and quality-assurance teams to assess:
- applicability, consistency with clinical practice, compliance with regulations,
- implementation and technical/standardization effects,
- source quality (evidence-based vs expert consensus).
- Providing a categorical information framework that helps researchers compare guideline application outcomes, drive revisions, and promote guideline adoption.
Who should use it
- Health informatics professionals and EHR/clinical registry vendors integrating TCM guideline evaluation data.
- Hospitals, clinical audit teams and guideline implementation managers assessing TCMCPG application.
- Standards bodies, researchers and policy-makers involved in TCM guideline evaluation, promotion and revision.
- Developers of evaluation tools and platforms that need a consistent semantic model for TCMCPG appraisal.
Related standards
- Developed by ISO/TC 215 (Health informatics) in collaboration with ISO/TC 249 (Traditional Chinese Medicine).
- Linked conceptually to other ISO health-informatics terminology documents cited in the specification (for example references used within the text such as ISO 20184-1 and ISO 13131). The document itself contains no normative references.
- Complements guideline-appraisal frameworks (e.g., AGREE) by focusing on application evaluation and representation for TCM contexts.
