Software & AI as Medical Device

Overview​

This page covers advanced considerations for software medical devices and AI/ML-based devices. For foundational qualification and IEC 62304 requirements, see Software as a Medical Device and Cybersecurity.

AI/ML Device Lifecycle Considerations​

AI/ML-based medical devices in Switzerland present unique regulatory challenges because the algorithm may continue to learn, be updated, or adapt post-market. These changes must be managed through a Predetermined Change Control Plan (PCCP) to avoid triggering new conformity assessments for routine updates.

  • Predetermined Change Control Plan (PCCP) — describes planned algorithm changes and the associated risk management and performance monitoring framework; reduces the need for new conformity assessment for every update
  • Algorithm transparency — training data sources, data preprocessing, model architecture, and validation methodology must be documented in technical documentation
  • Performance monitoring post-market — real-world performance monitoring is integral to the PMS plan for AI/ML devices; distribution shift and model drift must be detected and managed

Swissmedic Expectations​

Swissmedic aligns with MDCG guidance and is monitoring the EU AI Act's implications for high-risk AI systems. For AI/ML medical devices, Swissmedic expects: comprehensive intended use and intended user specification; full documentation of the training/validation/test data split; an ongoing performance monitoring plan integrated with PMS.

Clinical Evaluation for AI/ML Devices

AI/ML-based medical devices require a robust clinical evaluation that demonstrates safety and performance in real-world conditions. The clinical evaluation plan must address: validation of the algorithm's clinical utility; evaluation of performance across different patient populations and data scenarios; assessment of potential failure modes and their clinical consequences; post-market surveillance plan to detect performance degradation or unexpected clinical outcomes.

Regulatory Basis

AI/ML-based medical devices in Switzerland must comply with MedDO and IEC 62304 (Medical device software lifecycle processes). The Predetermined Change Control Plan (PCCP) is a critical component of the technical documentation for devices with planned post-market algorithm updates and must be validated by the Notified Body as part of the conformity assessment.
