EU MDR — AFAP, not ALARP: For CE-marked devices, risks must be reduced as far as possible (AFAP) without economic considerations (MDR Annex I, GSPR 1–4; EN ISO 14971:2019/A11:2021 Z-annexes deviation). ALARP ("as low as reasonably practicable"), which permits cost-benefit weighing in acceptability decisions, is not an acceptable criterion under the EU MDR — a notified body will flag it. ISO 14971:2019 itself removed ALARP from the normative text. ALARP may persist in some non-EU jurisdictions (e.g., the UK HSE tradition); if used outside the EU, flag the deviation from EU requirements explicitly.
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 (EU MDR: still reduce as far as possible)
- Reduction required (AFAP): 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 Evaluation Decision Tree
Risk Estimated
│
▼
Apply Acceptability Criteria
│
├── Low Risk ──────────► Accept and document
│
├── Medium Risk ───────► Reduce as far as possible (AFAP)
│ │ Document why further reduction impossible
│ ▼
│ Further reduction possible?
│ │
│ Yes──► Implement control
│ No───► Document AFAP rationale (no economic considerations)
│
├── High Risk ─────────► Risk reduction required
│ │ Must demonstrate reduction AFAP
│ ▼
│ Implement control
│ Verify residual risk

└── Unacceptable ──────► Design change mandatory
Cannot proceed without control
AFAP Demonstration Requirements (EU MDR)
| Criterion |
Evidence Required |
| All control options considered |
Analysis of every feasible control per the hierarchy (design, protective measures, information) |
| Further reduction impossible |
Evidence each remaining option is technically infeasible or does not further reduce risk |
| State of the art |
Comparison to similar devices and current standards |
| Stakeholder input |
Clinical/user perspectives |
Economic considerations (cost of further risk reduction) must not enter the EU acceptability decision (MDR Annex I GSPR 2; EN ISO 14971:2019/A11:2021). Cost may inform business decisions about whether to market the device — never whether a risk is acceptable.

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
