Risk Management

Risk Management is a fundamental requirement for medical device manufacturers worldwide, providing a systematic approach to ensure device safety throughout the entire product lifecycle. The internationally recognized standard ISO 14971 defines the framework for medical device risk management.

What Risk Management involves:
- Identification of known and foreseeable hazards
- Estimation and evaluation of associated risks
- Control of risks to acceptable levels
- Monitoring and reviewing risk control effectiveness
- Documentation of the entire process

ISO 14971 Risk Management Process:
1. Risk Analysis - Identify hazards and hazardous situations
2. Risk Evaluation - Determine if risks are acceptable
3. Risk Control - Implement measures to reduce risks
4. Overall Residual Risk Evaluation - Assess cumulative risk
5. Risk Management Review - Ensure completeness and effectiveness
6. Production and Post-Production - Monitor and update

Common Risk Analysis Methods:
- FMEA (Failure Mode and Effects Analysis) - Systematic analysis of potential failure modes
- Fault Tree Analysis (FTA) - Top-down deductive analysis of failures
- Hazard Analysis and Critical Control Points (HACCP) - Preventive approach to hazards
- Preliminary Hazard Analysis (PHA) - Early-stage risk identification

Risk Control Hierarchy:
1. Inherent safety by design - Eliminate or reduce risks through design
2. Protective measures - Add safeguards to the device or manufacturing process
3. Information for safety - Warnings, precautions, training materials

Risk-Benefit Analysis: Regulators require demonstration that benefits outweigh residual risks. This is critical for high-risk Class III devices and novel technologies.

Post-Market Risk Management: Manufacturers must continuously monitor field performance, complaint trends, adverse events, and update risk assessments based on real-world data.
