Overview
ISO/TS 16551:2025 - Health informatics - Reference model for virtual reality (VR)-based clinical practice simulation - defines a structured reference model to support the design, development and interoperability of VR-based clinical simulators. The Technical Specification describes the architecture, components, data elements and data types, user roles, and relationships needed to build realistic, patient‑safe virtual clinical training environments. Its aim is to promote openness, interoperability and efficiency in developing VR clinical simulations and virtual patients.
Key Topics
- Scope & purpose: a reference model for VR-based clinical practice simulation covering components, relations, data elements/types, and user roles.
- Two main models:
- Simulation practice model - organized around Goal, Scenario, Task, and Activity to structure learning objectives and stepwise clinical practice.
- Simulation data model - defines data used to construct realistic simulations: information on subject of care, health summary record, and VR-related data (graphics, sound, text).
- Components & data types: explicit data type definitions for goal, scenario, task, activity, subject-of-care information, health summary records, VR assets, and roles.
- Terminology & architecture: clear definitions (e.g., virtual reality, subject of care, role, component, architecture) to ensure common understanding across implementers.
- Interoperability focus: standardized component interfaces and data models to enable reuse, integration with health IT, and consistent simulation behavior.
- Implementation guidance: structured model intended to reduce development time, protect patient privacy, and enable consistent learner assessment.
Applications
ISO/TS 16551:2025 is practical for:
- VR simulation developers creating clinical training products and virtual patients.
- Health informatics architects designing simulator integration with EHRs or learning management systems.
- Medical and nursing educators structuring curricula and scenario libraries based on standardized Goals and Scenarios.
- Clinical skills assessment and accreditation bodies seeking consistent scenario definitions and outcome tracking.
- Researchers evaluating simulation effectiveness and comparing interventions across platforms.
Typical use cases include developing interoperable VR scenarios (CPR, delivery, emergency care), exchanging standardized health-summary inputs for realistic virtual patients, and implementing role-based learning workflows.
Related Standards
This Technical Specification sits within ISO health informatics work (ISO/TC 215) and references established terminology and concepts found in related standards (for example, ISO/IEC definitions for VR and ISO standards for health summary records). Implementers should consider related health informatics standards when integrating simulators with clinical data and certification processes.
