What Documentation is Required for Medical Device Field Service Visits

Medical device field service visits require comprehensive documentation including pre-visit planning records (work orders, device history, and regulatory compliance status), on-site service reports (detailed maintenance activities, parts replaced, calibration results, and technician observations), and post-visit compliance documentation (customer sign-offs, updated device logs, adverse event reports if applicable, and certificates of conformity that meet FDA 21 CFR Part 820 and ISO 13485 standards). This documentation serves as legal proof of service, ensures regulatory traceability for audits, maintains device warranty validity, and protects both the service organization and healthcare facility from liability while supporting continuous quality improvement and patient safety protocols. All records must be retained according to regulatory requirements, typically ranging from two years to the lifetime of the device plus additional years as mandated by governing bodies like the FDA, Health Canada, or EU MDR authorities.
