IMDRF Software as a Medical Device (SaMD) Risk Categorization Framework

Categorizing SaMD across Category I to IV based on state of healthcare condition and significance of information provided.

Executive Overview

The International Medical Device Regulators Forum (IMDRF) SaMD framework harmonizes global classification for standalone medical software across the FDA, EU MDR, Health Canada, and Japan PMDA.

1. The 2D SaMD Risk Matrix (Condition vs Significance)

The IMDRF framework intersects two primary dimensions to determine risk Category (I, II, III, or IV):

  • Healthcare Situation / Condition: Critical (life-threatening), Serious (potential permanent impairment), or Non-serious.
  • Significance of Information Provided: Treat or diagnose, Drive clinical management, or Inform clinical management. Software that diagnoses a Critical condition falls into Category IV (highest risk, requiring clinical trials), whereas software informing management of a Non-serious condition is Category I.

Frequently Asked Questions

Why is the IMDRF SaMD framework recognized globally?

It eliminates fragmented regional definitions, enabling medical software companies to use a single unified clinical evaluation and risk documentation baseline across the US, Europe, and Asia.
