Risk Analysis Workflow
Identify hazards and estimate risks systematically.
Workflow: Conduct Risk Analysis
- Define intended use and reasonably foreseeable misuse:
- Medical indication
- Patient population
- User population
- Use environment
- Select analysis method(s):
- FMEA for component/function analysis
- FTA for system-level analysis
- HAZOP for process deviations
- Use Error Analysis for user interaction
- Identify hazards by category:
- Energy hazards (electrical, mechanical, thermal)
- Biological hazards (bioburden, biocompatibility)
- Chemical hazards (residues, leachables)
- Operational hazards (software, use errors)
- Determine hazardous situations:
- Sequence of events
- Foreseeable misuse scenarios
- Single fault conditions
- Estimate probability of harm (P1-P5)
- Estimate severity of harm (S1-S5)
- Document in hazard analysis worksheet
- Validation: All hazard categories addressed; all hazards documented; probability and severity assigned

Risk Evaluation Workflow
Evaluate risks against acceptability criteria.
Workflow: Evaluate Identified Risks
- Calculate initial risk level from probability × severity
- Compare to risk acceptability criteria
- For each risk, determine:
- Acceptable: Document and accept
- ALARP: Proceed to risk control
- Unacceptable: Mandatory risk control
- Document evaluation rationale
- Identify risks requiring benefit-risk analysis
- Complete benefit-risk analysis if applicable
- Compile risk evaluation summary
- Validation: All risks evaluated; acceptability determined; rationale documented

Risk Control Workflow
Implement and verify risk control measures.
Workflow: Implement Risk Controls
- Identify risk control options:
- Inherent safety by design (Priority 1)
- Protective measures in device (Priority 2)
- Information for safety (Priority 3)
- Select optimal control following hierarchy
- Analyze control for new hazards introduced
- Document control in design requirements
- Implement control in design
- Develop verification protocol
- Execute verification and document results
- Evaluate residual risk with control in place
- Validation: Control implemented; verification passed; residual risk acceptable; no unaddressed new hazards
