FDA's Quality System Regulation (QSR) for Medical Devices

Updated: Feb 17


Medical devices are integral to modern healthcare, aiding in diagnosis, treatment, and management of various medical conditions. As these devices directly impact patient safety and well-being, it is crucial to establish rigorous regulatory frameworks to ensure their quality and efficacy. The Food and Drug Administration (FDA), a key regulatory authority in the United States, takes on the responsibility of safeguarding public health by overseeing the medical device industry and enforcing stringent guidelines.

Medical devices are integral to modern healthcare, aiding in diagnosis, treatment, and management of various medical conditions. As these devices directly impact patient safety and well-being, it is crucial to establish rigorous regulatory frameworks to ensure their quality and efficacy. The Food and Drug Administration (FDA), a key regulatory authority in the United States, takes on the responsibility of safeguarding public health by overseeing the medical device industry and enforcing stringent guidelines.


The field of medical devices is diverse and ever-evolving, ranging from simple, over-the-counter devices to complex, implantable life-saving technologies. Regardless of their complexity, all medical devices must undergo a stringent approval process to reach the market. This process involves a careful assessment of the device's design, manufacturing, and post-market surveillance to mitigate potential risks and ensure optimal patient outcomes.


Overview of the FDA's Quality System Regulation


The Quality System Regulation, outlined in Title 21 of the Code of Federal Regulations (CFR), Chapter I, Subchapter H, Part 820, pertains specifically to medical devices. It sets forth a framework of regulations that medical device manufacturers must adhere to in order to meet the FDA's quality standards. The QSR encompasses various aspects of device design, production, and post-market surveillance, ensuring that medical devices are safe, effective, and meet the intended purpose.


General Requirements


Under the QSR, General Requirements, as defined in Section 820.180, encompass essential provisions that medical device manufacturers must follow concerning record-keeping and documentation. These requirements are aimed at ensuring the traceability, accountability, and accessibility of critical information related to medical devices throughout their lifecycle.

  • Records Maintenance and Accessibility

One of the primary elements of the General Requirements is the maintenance and accessibility of records. Medical device manufacturers are mandated to keep all records required by the QSR at their manufacturing establishment or another location that is reasonably accessible to responsible officials of the manufacturer and FDA employees designated to perform inspections. These records may include design documentation, production records, quality control data, complaint records, and more. By maintaining such records, manufacturers provide a transparent and comprehensive account of their device's journey from conception to market distribution.

  • Legibility and Storage

The legibility and proper storage of records are vital to ensure the integrity and usability of the information contained therein. Records must be legible to facilitate easy review and interpretation. Additionally, they should be stored in a manner that minimizes deterioration and prevents loss due to environmental factors or mishandling. Proper storage procedures also help ensure that historical data can be referenced and analyzed effectively whenever necessary.

  • Confidentiality

Certain information within these records may be deemed confidential by the manufacturer. In such cases, manufacturers can mark these records to assist the FDA in determining whether the information can be disclosed under the public information regulation stated in part 20 of Title 21 CFR. Confidentiality protections aim to strike a balance between transparency and protecting sensitive business information, such as proprietary designs or trade secrets.

  • Record Retention Period

The General Requirements dictate a specific record retention period for medical device manufacturers. All records required by the QSR must be retained for a period equivalent to the design and expected life of the device, but in no case less than 2 years from the date of the device's release for commercial distribution by the manufacturer. This provision ensures that historical data regarding the device's design, production, and performance is available for analysis and review even after it has been commercially distributed. This information becomes invaluable during post-market surveillance and potential recalls, allowing manufacturers and the FDA to make informed decisions about the device's safety and efficacy.

  • Exceptions

Section 820.180 specifies exceptions to the General Requirements. Notably, this section does not apply to the reports required by § 820.20(c) Management review, § 820.22 Quality audits, and supplier audit reports used to meet the requirements of § 820.50(a) Evaluation of suppliers, contractors, and consultants. However, it clarifies that these exceptions only apply to the reports themselves and not the procedures established under these provisions. Medical device manufacturers must still comply with documentation and certification requirements for these exceptional cases upon request by designated FDA employees. This ensures that critical aspects of the manufacturing process and quality control are adequately documented and audited to uphold the highest standards of safety and performance.


The General Requirements under the FDA's Quality System Regulation play a pivotal role in ensuring the safety, quality, and effectiveness of medical devices. By maintaining comprehensive records and adhering to the specified provisions, medical device manufacturers can demonstrate compliance with FDA standards and contribute to the overall improvement of healthcare services.


For consumers, this regulation offers reassurance that the medical devices they use have undergone stringent quality control measures, protecting their health and well-being. As medical technology continues to advance, the FDA's commitment to enforcing the Quality System Regulation remains paramount to promoting public health and well-being. Manufacturers, in turn, must remain diligent in meeting these General Requirements to create and maintain safe and effective medical devices for the benefit of patients worldwide.
