Overview
ISO/TS 22703:2021 - Health informatics - Requirements for medication safety alerts - provides vendor- and implementer-focused requirements to standardize medication safety alert systems used in clinical decision support systems (CDSS). The technical specification applies to CDSS whether or not they are medical devices and targets alert content, terminology, knowledge base selection, alert display, interoperability with EHR/CPOE/pharmacy systems, and quality measurement to improve alert effectiveness. It does not cover the development of rule content, the algorithms that generate alerts, or the creation of alert processors themselves.
Key topics and requirements
The standard organizes requirements around practical, safety-focused areas:
- Terminology and definitions: consistent clinical and medication terminology to reduce ambiguity in alerts.
- Potential medication problem types: standardized categories of drug-related safety risks to guide alert scope and consistency.
- Knowledge base selection: criteria for choosing evidence-based resources and knowledge bases that underpin medication safety alerts.
- Data sources: recommended use of evidence-based references and appropriate patient data sources (EHR, pharmacy data) to drive relevant alerts.
- Alert processor and functionality: requirements for how CDSS should handle and present alerts (note: development of processors or algorithms is out of scope).
- Alerting guidelines: severity/safety risk grading, alert schemas, display conventions, timing, intended recipients, and interventions to reduce clinically irrelevant notifications.
- Audit trails and quality measurement: logging, monitoring, and performance metrics to measure effectiveness and support continuous improvement.
- Interfaces and relations: interoperability requirements and relations to clinical information systems and pharmacy systems.
Practical applications and who uses it
ISO/TS 22703:2021 is intended for:
- EHR, CPOE and CDSS vendors seeking to align medication alert behavior and displays with international best practices.
- Pharmacy information system and PBM vendors implementing prospective drug-utilization-review (DUR) functionality.
- Healthcare organizations and health IT implementers deploying medication safety alerts to reduce medication errors and manage alert fatigue.
- Clinical safety officers and informaticians responsible for governance, audit, and quality improvement of medication alerts.
Practical benefits include more consistent alert content, reduced alert fatigue through severity grading and tailored displays, improved interoperability with EHR/pharmacy systems, and measurable quality metrics for ongoing optimization.
