Which device documentation identifies all changes made throughout the product lifecycle?

The Device History Record (DHR) is essential for tracking the complete history of a medical device from its design through its manufacturing and throughout its lifecycle. It is a compilation of records that demonstrate that the device was manufactured in accordance with the established requirements. The DHR includes various documents such as production and process control records, changes, and deviations that occurred during manufacturing, as well as the final device specifications.

By maintaining a DHR, the manufacturer ensures compliance with regulatory requirements and facilitates traceability, which is crucial for both quality control and post-market surveillance. It includes documentation that outlines all changes made to the device during the production process, allowing manufacturers to assess how modifications might affect the device's safety and effectiveness over time. This comprehensive tracking of changes is vital for regulatory inspections, audits, and in the event of product recalls.

In contrast, other options serve different purposes: the Device Master File (DMF) pertains to detailed information about the device, the Design History File (DHF) focuses on the design inputs, outputs, and changes during the development of the device, and the Technical File is typically used in European regulatory contexts to collate design control information. None of these documents capture the entire history of changes made throughout the lifecycle of the device
