ISO 13485 Requirements

ISO 13485:2016 for medical device quality management systems provides comprehensive guidelines for change control. It mentions change over 30 times, highlighting its importance in quality management.

Section 4.1.4 of ISO 13485 is explicitly dedicated to managing changes to an organization’s QMS processes and complying with regulatory change control requirements.

Key aspects of ISO 13485 change control requirements include:

  1. Evaluating changes for their impact on both the QMS and the medical devices produced under it
  2. Controlling changes according to the standard and applicable regulatory requirements
  3. Maintaining detailed documentation and traceability of every change within a QMS.

FDA Regulations

The U.S. Food and Drug Administration (FDA) has established regulations for change control in medical devices through 21 CFR Part 820, also known as the Quality System Regulation (QSR). While the FDA does not have a standalone requirement for change control, it addresses this critical aspect in three different sections:

  1. 21 CFR 820.30(i) Design Controls
  2. 21 CFR 820.40(b) Document Control
  3. 21 CFR 820.70(b) Production and Process Changes

These regulations require manufacturers to establish and maintain procedures for the identification, documentation, validation or verification, review, and approval of design changes before their implementation. They also mandate the review and approval of document changes by appropriate personnel and the maintenance of change records.

The FDA has published two important guidances to help stakeholders determine when modifications to legally marketed devices require new premarket notification (510(k)) submissions:

  1. Deciding When to Submit a 510(k) for a Change to an Existing Device (General Modifications guidance)
  2. Deciding When to Submit a 510(k) for a Software Change to an Existing Device (Software Modifications guidance)

These guidances provide a risk-based approach to evaluate whether a change likely requires a new 510(k) and include flowcharts, examples, and recommendations for proper documentation of device changes.

Other Applicable Standards

In addition to ISO 13485 and FDA regulations, other regulatory bodies and standards play a role in shaping the change control framework for medical devices:

  1. Health Canada: Relies on ISO 13485:2016 for document and design change management
  2. European Commission: Utilizes ISO 13485:2016 and has specific requirements under the Medical Device Regulation (MDR) and In Vitro Diagnostic Regulation (IVDR)
  3. MDCG 2020-3 Rev 1: Provides guidance on change control for medical devices in the European Union

These regulatory bodies and standards emphasize the need for a systematic approach to manage and control changes to products, processes, procedures, equipment, and systems in the medical device industry.
