Overview
SIST-TS CEN/ISO TS 22703:2021, titled Health informatics - Requirements for medication safety alerts (ISO/TS 22703:2021), specifies comprehensive requirements for the design and operation of medication safety alert systems. Developed by SIST in collaboration with ISO and CEN, this technical specification aims to standardize medication alert functions across healthcare settings, improving patient safety by minimizing medication errors.
The standard applies to clinical decision support systems (CDSSs), whether or not classified as medical devices, and focuses on ensuring medication-related alerts are functionally sound, terminologically consistent, and effective in preventing harm. Relevant for healthcare organizations, system vendors, and implementors, the document outlines foundational criteria for terminology, knowledge base selection, alert display, and quality measurement mechanisms.
Key Topics
This standard addresses essential topics to guide the development and deployment of robust medication safety alert systems:
- Standardized Terminology for Alerts: Establishes terminology requirements, ensuring clarity and consistency in how medication safety is communicated to clinicians.
- Knowledge Base Selection: Provides guidance on choosing reliable and comprehensive knowledge bases for supporting alert generation, crucial for effective CDSS operation.
- Functionality Requirements: Details required system features, including processes for identifying and managing medication safety issues such as therapeutic duplications, drug-disease contraindications, adverse drug interactions, incorrect dosages, and treatment durations.
- Alert Display Requirements: Specifies how medication safety alerts should be displayed to optimize interpretation, including considerations for user interface and timely presentation at the point of care.
- Quality Measurement and Improvement: Recommends mechanisms for monitoring and measuring alert performance, aiming to reduce alert fatigue and increase actionable relevance, ultimately enhancing patient safety outcomes.
Applications
Adopting SIST-TS CEN/ISO TS 22703:2021 delivers practical benefits for healthcare IT and clinical practice:
- Healthcare Organizations: Hospitals and clinics can use this standard to guide the selection and configuration of medication alert functionalities in their EHR, CDSS, or pharmacy systems, supporting regulatory compliance and risk management.
- System Vendors and Implementors: Developers of electronic health records, pharmacy systems, and integrated CDSSs leverage these requirements to ensure their medication alert modules deliver relevant, actionable, and standardized safety warnings that integrate seamlessly with clinical workflows.
- Patient Safety Initiatives: With structured alert requirements, organizations can reduce preventable adverse drug events by providing prescribers and dispensers with timely, evidence-based alerts tailored to patient-specific factors.
- Regulatory and Quality Assurance: By following recognized alert system benchmarks, stakeholders facilitate alignment with national or regional medication safety policies and performance monitoring initiatives.
Related Standards
The SIST-TS CEN/ISO TS 22703:2021 standard references and works in conjunction with several key international standards in health informatics:
- ISO/TS 22756: Health informatics - Requirements for a knowledge base for clinical decision support systems to be used in medication-related processes.
- ISO 27789: Health informatics - Audit trails for electronic health records, supporting traceability and accountability for alert actions.
- IEC 82304-1: Health software - Part 1: General requirements for product safety, addressing software quality and safety in health applications.
By harmonizing with these established standards, SIST-TS CEN/ISO TS 22703:2021 supports the integration of best practices for medication safety alerts across diverse health IT ecosystems, promoting safer and more effective medication use on a global scale.
