Navigating the Transition from QSR to QMSR: A Comprehensive Guide for Medical Device Professionals

Dr. Sathesh Kumar Annamalai

In February 2026, the U.S. Food and Drug Administration (FDA) will officially transition from the long-established Quality System Regulation (QSR), outlined in 21 CFR Part 820, to the new Quality Management System Regulation (QMSR). This shift signifies a critical evolution in regulatory compliance for medical device manufacturers, moving toward global harmonization with ISO 13485:2016, the internationally recognized standard for medical device quality management systems (QMS).

This transition promises to bring more clarity, reduce regulatory complexity, and eliminate redundant processes for manufacturers that operate in both U.S. and global markets. However, it also introduces a set of challenges that must be addressed, including significant changes in terminology, enhanced risk management requirements, and more comprehensive documentation standards. This article will provide an in-depth exploration of these changes, offering actionable insights for how manufacturers can navigate the QMSR transition successfully, ensuring full compliance by the 2026 deadline.

1. What is the QMSR, and Why is it Important?

The Quality Management System Regulation (QMSR) is the FDA’s modernized approach to regulating medical device quality systems. By incorporating key aspects of ISO 13485:2016, the QMSR marks a significant shift toward aligning U.S. regulatory requirements with global standards. This move is long overdue, as the Quality System Regulation (QSR), enacted in 1996, has remained largely unchanged for more than two decades despite ongoing advancements in global regulatory expectations.

ISO 13485:2016 is the international benchmark for medical device quality management, and its adoption into FDA regulations is expected to streamline compliance for manufacturers who must navigate multiple regulatory frameworks. In doing so, the QMSR reduces duplicative processes and creates a pathway for manufacturers to meet both U.S. and international regulatory obligations more efficiently.

The Rationale Behind the Transition

The FDA’s decision to transition to the QMSR reflects the agency’s strategic goal of facilitating global harmonization while ensuring product safety and effectiveness. The key drivers behind this transition include:

• Facilitating Global Market Access: By adopting ISO 13485:2016, the FDA is making it easier for U.S. device manufacturers to achieve compliance in other major markets, such as the European Union, Australia, Canada, and Japan, where ISO 13485 is the recognized standard.
• Enhancing Regulatory Efficiency: The harmonization of U.S. and international regulations will reduce the need for companies to maintain separate quality systems to meet varying regional requirements, thereby streamlining operations and reducing costs.
• Improving Product Safety: ISO 13485:2016 takes a risk-based approach to quality management, which encourages proactive identification and mitigation of risks throughout the product lifecycle. This risk-based methodology ensures greater patient safety and improved device effectiveness.

The move to QMSR is seen as an essential evolution in ensuring that U.S. regulations remain relevant in an increasingly globalized industry, and it reflects the FDA’s commitment to improving both regulatory outcomes and industry performance.

2. Key Differences Between QSR and QMSR

To better understand how QMSR will affect medical device manufacturers, it’s important to explore the key differences between the QSR and QMSR frameworks. These changes will impact nearly every aspect of how companies design, develop, and market medical devices in the U.S.

Scope:

• QSR: Primarily focused on manufacturing and quality control processes, with limited attention to post-market activities.
• QMSR: Expands the scope to cover the entire product lifecycle, including design, development, production, risk management, and post-market surveillance activities.

By broadening its scope, QMSR ensures that manufacturers are not only focused on producing compliant products but are also responsible for maintaining device safety and effectiveness throughout its entire lifecycle.

Risk Management:

• QSR: Mentions risk management mainly in the context of design controls, with limited emphasis on broader risk-based decision-making.
• QMSR: Adopts a comprehensive, risk-based approach throughout the product lifecycle, requiring systematic risk identification, assessment, control, and ongoing monitoring.

The risk-based approach of ISO 13485:2016 ensures that risks are identified, mitigated, and continuously managed across all stages of a device’s lifecycle, from initial design through post-market activities.

Quality Management System (QMS):

• QSR: Provides a general framework for implementing a QMS, with specific documentation requirements for certain activities (e.g., design controls, complaint handling).
• QMSR: Requires a more detailed, structured QMS that aligns with ISO 13485:2016. This includes enhanced requirements for risk management, quality planning, assurance, and post-market surveillance.

QMSR goes beyond the basic framework of QSR by mandating a system-wide focus on risk management, supplier controls, and more comprehensive document control processes.

Documentation:

• QSR: Requires specific documentation for certain aspects of the QMS, such as design controls, quality records, and complaint handling.
• QMSR: Demands more comprehensive documentation, including risk management plans, design and development files, production records, and post-market surveillance reports.

This shift toward enhanced documentation is driven by ISO 13485’s emphasis on traceability and accountability throughout the lifecycle of the device. Manufacturers will need to ensure that all records are complete, accurate, and accessible for review.

3. Terminology Changes: Say Goodbye to DMR, DHF, and DHR

One of the most visible changes in the transition from QSR to QMSR is the overhaul of familiar terminology. Under the QSR, medical device manufacturers have relied on terms like Device Master Record (DMR), Design History File (DHF), and Device History Record (DHR). However, the QMSR replaces these terms with the Medical Device File (MDF), a concept derived from ISO 13485:2016. This consolidation streamlines the documentation requirements by reducing overlap and complexity.

Key Term Changes:

• DMR ?? MDF (Medical Device File): The Medical Device File (MDF) will contain all the product specifications, manufacturing procedures, and labeling requirements previously housed in the DMR.
• DHF ?? Design and Development File: This file will capture the entire design and development process, aligning with the risk-based approach outlined in ISO 13485.
• DHR ?? Production Record: The production record will ensure that a traceable history of each manufactured device is maintained, consistent with ISO 13485 requirements.

Although the terminology has changed, the core requirements for maintaining these records have not. Manufacturers will still be expected to maintain complete and accurate records that ensure traceability and accountability throughout the product lifecycle.

Impact of Terminology Changes:

While the transition to new terminology may seem daunting, it actually reflects a more streamlined and internationally harmonized approach to documentation. For manufacturers already familiar with ISO 13485, these changes will not introduce new requirements, but it will be essential to update internal documentation, procedures, and training materials to ensure alignment with the new terms.

Action Items:

• Update Terminology: Ensure that all internal documentation, training materials, and standard operating procedures (SOPs) reflect the new QMSR terminology.
• Conduct Staff Training: Provide training sessions for employees to familiarize them with the new terminology and its implications for daily operations.

4. Focus on a Risk-Based Approach

ISO 13485:2016 emphasizes the importance of a risk-based approach throughout the QMS, requiring manufacturers to identify, assess, control, and continuously monitor risks across all phases of a product’s lifecycle. This represents a shift away from the more reactive approach of the QSR, which focused primarily on risk during product design.

Key Elements of a Risk-Based Approach:

1. Risk Identification: Manufacturers must proactively identify potential risks associated with design, development, production, supplier management, and post-market activities.
2. Risk Assessment: Once risks are identified, they must be assessed for their potential impact on device safety and effectiveness.
3. Risk Control: Manufacturers must implement appropriate controls to mitigate identified risks, ensuring that they remain within acceptable levels.
4. Ongoing Monitoring: Risk management does not stop once the device is on the market. Manufacturers must continually monitor for new risks, adjust controls as necessary, and document all risk-related activities.

This comprehensive, lifecycle-wide approach to risk management ensures that manufacturers are continually focused on device safety and effectiveness, even after the product has been released into the market.

Action Items:

• Implement a Comprehensive Risk Management System: Ensure that your QMS includes procedures for identifying, assessing, and controlling risks across all areas of the business.
• Integrate Risk Management into Supplier Controls: Extend risk management processes to include supplier selection, monitoring, and evaluation to ensure that third-party risks are adequately controlled.

5. Enhanced Requirements for Document Control

One of the significant improvements introduced by QMSR is the enhanced focus on document control, especially with respect to documents of external origin, such as supplier certifications and regulatory guidelines. ISO 13485:2016 mandates that manufacturers control these external documents to ensure they are current, accurate, and properly approved.

Action Items:

• Update Document Control Procedures: Ensure that all documents of external origin, including supplier records and regulatory guidelines, are properly managed and integrated into your QMS.
• Implement Automated Document Control Systems: Consider upgrading to an automated document management system to streamline the approval, storage, and retrieval of key documents.

6. Electronic Signatures and Records: Aligning with 21 CFR Part 11

While ISO 13485:2016 does not address the use of electronic records and signatures, the QMSR specifically requires compliance with 21 CFR Part 11, which governs the use of electronic records and signatures in FDA-regulated industries. This means that manufacturers using electronic systems for document control must ensure that these systems meet FDA requirements for security, traceability, and validation.

Key Requirements of 21 CFR Part 11:

1. System Validation: Electronic systems must be validated to ensure that they produce accurate and reliable records.
2. Audit Trails: Systems must maintain an audit trail that tracks all changes to records, including who made the change and when.
3. Electronic Signatures: Electronic signatures must be secure and traceable, with proper authentication to ensure that the signer is authorized to approve the document.

Action Items:

• Review Your Electronic Systems for Compliance: Conduct a thorough review of your electronic record-keeping systems to ensure compliance with 21 CFR Part 11.
• Develop Procedures for Electronic Records and Signatures: Implement SOPs that govern the use of electronic records, ensuring that they meet FDA requirements for security and traceability.

7. Labeling and Packaging: New Emphasis on Control

Labeling and packaging errors are a leading cause of medical device recalls. To address this issue, the QMSR introduces specific requirements for labeling and packaging controls under Section 820.45. These controls are designed to ensure that device labels are accurate, legible, and complete, and that packaging is designed to protect the device during distribution and storage.

Key Labeling and Packaging Requirements:

• Unique Device Identifier (UDI): All labels must include the UDI, which provides critical information about the device, such as its manufacturer, model, and expiration date.
• Label Inspection: The QMSR requires a representative sample of labels to be physically inspected for accuracy before release, even if automated systems are used for initial label verification.
• Packaging Controls: Manufacturers must implement controls to ensure that packaging protects the device during distribution and storage, preventing damage or contamination.

Action Items:

• Review Labeling and Packaging Procedures: Ensure that your labeling and packaging controls meet the new requirements, including the handling of UDI and accurate label inspections.
• Implement a Physical Label Inspection Process: Even if automated systems are used for label verification, ensure that a representative sample of labels is physically inspected before release.

8. What’s Staying the Same?

While the QMSR introduces many changes, certain elements of the QSR will remain intact. For example:

• Complaint Handling and CAPA Procedures: These procedures remain critical to ensuring product quality and safety, and the FDA will continue to require manufacturers to investigate complaints and implement corrective and preventive actions (CAPAs) as necessary.
• Management Responsibility: The FDA has renamed “Management with Executive Authority” to Top Management, but the responsibilities and expectations remain largely the same. Top management must ensure that the QMS is effectively implemented and maintained, and that resources are allocated appropriately.

Key Takeaway:

For manufacturers already compliant with both QSR and ISO 13485:2016, the transition should not present a significant burden, as many of the requirements are substantively similar.
