Medical Device Instructions for Use Usability Audit Checklist

Role: Senior Human Factors & Usability Technical Documentation Specialist specializing in medical device labeling and ISO 20417 compliance.

Context

• Device Name: {{device_name}}
• Device Classification: {{device_classification}}
• Primary User Population: {{primary_user_population}}
• Use Environment: {{use_environment}}
• Critical Hazard Profile: {{critical_hazard_profile}}
• Applicable Usability Standard: {{applicable_standard}}

Task

Construct an end-to-end technical usability and regulatory audit checklist for the Instructions for Use (IFU) manual accompanying {{device_name}} to minimize use errors and ensure compliance.

Method

1. Review the operational profile of {{device_name}} across the expected {{use_environment}} conditions.
2. Map the technical literacy and physical requirements of {{primary_user_population}} against reading levels, font sizes, and layout choices.
3. Align all contraindications, warnings, and precautions with the risk controls documented in {{critical_hazard_profile}}.
4. Design verification checkpoints for step-by-step setup, calibration, operation, and maintenance procedures.
5. Audit emergency, fault-state, and troubleshooting instructions for clarity during high-stress failure scenarios.
6. Create compliance checkpoints specifically tailored to {{applicable_standard}} and {{device_classification}} labeling mandates.
7. Review cleaning, disinfection, and disposal workflows for clarity and biological safety warnings.
8. Structure the checklist into distinct operational lifecycle phases with evaluation scoring criteria.

Constraints

• MUST directly cross-reference safety warnings to {{critical_hazard_profile}}.
• MUST evaluate instructions for accessibility and cognitive load specific to {{primary_user_population}}.
• MUST NOT include subjective phrasing; use explicit criteria (e.g., active voice, imperative mood, numbered sequence).
• The checklist must support both print and digital IFU verification.

Output format

• Audit Overview: Brief summary of device metadata and target audience considerations.
• Section 1: Pre-use, Setup, and Accessibility Checks (5 items).
• Section 2: Core Operational & Usability Verification (6 items).
• Section 3: Risk Communication, Warnings & Emergency Procedures (6 items).
• Section 4: Maintenance, Reprocessing & Standards Compliance (5 items).
• Format: Markdown checklist with task boxes [ ], containing Criteria, Standard / Risk Mapping, and Acceptance Benchmark.

Self-review

• Ensure every critical hazard in {{critical_hazard_profile}} has an explicit verification check.
• Check that terminology reflects medical device labeling norms (e.g., ISO 15223-1 symbols, IEC 62366-1).
• Confirm total item count is exactly 22 items.
