Health Hazard Evaluation (HHE) – Overview

A Health Hazard Evaluation (HHE) is a critical process used to assess the potential risks associated with medical devices that may present safety, performance, or quality concerns. It serves as a foundational step in determining whether corrective or recall actions are necessary and helps manufacturers and regulators make informed, timely decisions to protect patient health.

An effective HHE examines the nature of the hazard, evaluates potential clinical outcomes, and determines the level of public health impact. This structured assessment supports regulatory compliance and ensures device manufacturers meet global post‑market expectations.

Key Components of an HHE

  1. Risk Assessment

    2. Identifies and analyzes potential health risks associated with defective, malfunctioning, or non‑conforming medical devices.

    Includes evaluation of:
    • Severity of harm
    • Probability of occurrence
    • Affected patient populations
    • Clinical consequences
  1. Regulatory Compliance
    2. Ensures alignment with global regulatory requirements such as:
    • FDA expectations for recall classification
    • EU MDR post‑market vigilance requirements
    • ISO 13485 quality system documentation This ensures all decisions are defensible, traceable, and audit‑ready.
  1. Recall Decision Support
    2. HHEs support determining whether:
    • A recall is required
    • A field correction is sufficient
    • No action is needed

      • Manufacturers and regulators rely on HHE outcomes to understand the potential impact on public health and select appropriate corrective measures.
