21 CFR Part 820 QMSR Implementation Services (FDA Quality System Regulation)
Our 21 CFR Part 820 implementation services support medical device organisations in developing and implementing a compliant Quality Management System Regulation (QMSR) aligned with FDA requirements. Patient Guard provides expert guidance to ensure your Quality Management System (QMS) meets US FDA expectations and is inspection-ready.
21 CFR Part 820 QMSR Implementation Services
21 CFR Part 820, now known as the FDA Quality Management System Regulation (QMSR), establishes quality management system requirements for manufacturers of finished medical devices intended for the U.S. market.
Effective from 2 February 2026, the QMSR incorporates ISO 13485:2016 by reference, bringing FDA quality system requirements into closer alignment with the internationally recognised medical device quality management standard while maintaining additional FDA-specific regulatory requirements.
Manufacturers subject to 21 CFR Part 820 must establish and maintain a Quality Management System appropriate to their devices and activities, covering applicable processes throughout design, manufacture, packaging, labelling, storage, installation and servicing.
Patient Guard provides expert 21 CFR Part 820 QMSR implementation services, helping medical device manufacturers establish, transition, remediate and maintain Quality Management Systems aligned with both FDA QMSR and ISO 13485:2016 requirements.
Our consultants can support the complete implementation process, from initial gap analysis and QMS planning through procedure development, process implementation, staff training, internal auditing and FDA inspection readiness.
For organisations already operating an ISO 13485 Quality Management System, we can assess the existing QMS against the additional requirements and terminology of the FDA QMSR, helping identify and address gaps before FDA inspection.
Whether you are entering the U.S. medical device market for the first time, transitioning from the former FDA Quality System Regulation, or strengthening an existing QMS, Patient Guard provides a practical and structured approach to achieving and maintaining 21 CFR Part 820 QMSR compliance.

| 1. | QMS Governance & Management | Quality objectives, organisational responsibilities, management commitment, management review and oversight of the Quality Management System. |
| 2. | Document & Record Control | Processes for creating, approving, controlling, maintaining and retaining QMS documents and quality records. |
| 3. | Design & Development | Design planning, inputs, outputs, reviews, verification, validation, transfer and control of design and development changes, where applicable. |
| 4. | Supplier & Production Controls | Supplier evaluation and monitoring, purchasing controls, production processes, process validation, identification and traceability, as applicable. |
| 5. | Risk & CAPA Processes | Risk-based quality processes, nonconformity management, corrective action and continual improvement activities. |
| 6. | Complaints & FDA Reporting | Complaint handling processes and integration with applicable FDA requirements for Medical Device Reporting, corrections and removals. |
| 7. | Audits & Inspection Readiness | Internal audits, management review, QMS effectiveness monitoring, staff readiness and preparation for FDA inspections. |

How to Become NHS Procurement Ready: From DTAC to NHS Market Access
Preparing to sell digital health technology to the NHS requires more than completing DTAC. This guide explains how manufacturers can build a procurement-ready position by aligning regulatory compliance, clinical safety, data protection, cybersecurity, interoperability, accessibility and commercial evidence for NHS market access.
DCB0129 and Clinical Safety: What Digital Health Manufacturers Need for NHS DTAC
For digital health manufacturers preparing to enter the NHS, clinical safety can be one of the most important—and sometimes misunderstood—parts of DTAC.
It is not enough to demonstrate that your software works.
Manufacturers need to consider what could happen if the technology fails, produces incorrect information, presents information incorrectly, contributes to a workflow error or is used in circumstances that could expose patients to harm.
This is where clinical risk management and DCB0129 become particularly important.
NHS England identifies DCB0129 as the clinical risk management standard for manufacturers of health IT systems. Its counterpart, DCB0160, applies to health organisations deploying and using health IT systems. NHS England states that compliance with these standards is required under the Health and Social Care Act 2012.
For manufacturers working towards NHS DTAC readiness, understanding the distinction—and having the right clinical safety evidence—is essential.
DTAC Requirements Explained: The 5 Areas Digital Health Manufacturers Need to Get Right
If your digital health technology is heading towards the NHS, understanding the Digital Technology Assessment Criteria (DTAC) should be part of your market-access planning.
But one of the biggest mistakes manufacturers can make is treating DTAC as simply another questionnaire to complete.
The questions are only part of the process.
Behind your answers needs to be evidence showing that your technology and organisation have appropriate arrangements for clinical safety, data protection, technical security, interoperability, and usability and accessibility.
These five areas form the core of NHS DTAC. NHS England describes DTAC as national baseline criteria for digital health technologies entering NHS and social care.
For digital health manufacturers, the practical question is therefore not simply:
“Can we complete the DTAC assessment?”
It is:
“Can we demonstrate that our product meets the requirements?”
This guide looks at each of the five DTAC areas, the types of evidence manufacturers should consider and some of the common gaps that can delay NHS readiness.
