FDA's Medical Device Single Audit Program: A Comprehensive Guide

Ruth Jul 09, 2026

The U.S. Food and Drug Administration (FDA) has implemented the Medical Device Single Audit Program (MDSAP) to streamline regulatory audits for medical device manufacturers. This initiative aims to reduce the regulatory burden on companies while maintaining or enhancing the quality and safety of medical devices. By understanding the MDSAP, manufacturers can ensure compliance and improve their audit experience.

MDSAP is a collaboration between regulatory authorities from Australia, Brazil, Canada, Japan, and the United States. It allows a single audit to be recognized by multiple regulatory authorities, reducing the number of audits a manufacturer must undergo. This program covers quality management systems, product safety, and performance standards for medical devices.

MDSAP Audits: Overview and Benefits

MDSAP audits are conducted by Auditing Organizations (AOs) recognized by the participating regulatory authorities. These audits assess a manufacturer's quality management system against the requirements of ISO 13485:2016 and the relevant regulations of the participating authorities.

Benefits of MDSAP include:

  • Reduced audit burden: A single audit can be recognized by multiple authorities, reducing the number of audits a manufacturer must undergo.
  • Enhanced regulatory consistency: MDSAP promotes consistent regulatory requirements and audit processes across participating authorities.
  • Improved quality and safety: MDSAP helps ensure that medical devices meet high-quality and safety standards.

Eligibility and Scope

MDSAP is open to medical device manufacturers who wish to sell their products in Australia, Brazil, Canada, Japan, or the United States. The program covers quality management systems, product safety, and performance standards for medical devices, including software as a medical device (SaMD).

Manufacturers must meet the following eligibility criteria:

CE mark: Which route should you follow

  • ISO 13485:2016 certification: Manufacturers must be certified to the ISO 13485:2016 standard for quality management systems.
  • Recognized Auditing Organization: The manufacturer must engage an AO recognized by the participating authorities.

  1. Pre-assessment: The AO conducts a preliminary review of the manufacturer's quality management system to ensure it meets the MDSAP requirements.
  2. On-site audit: The AO conducts an on-site audit of the manufacturer's facilities and quality management system.
  3. Audit report: The AO prepares an audit report, including findings and recommendations, which is submitted to the participating regulatory authorities.
  4. Follow-up: If any non-conformities are identified, the manufacturer must address them and provide evidence of corrective actions to the AO and regulatory authorities.

MDSAP offers several advantages over traditional audits, including reduced audit burden, enhanced regulatory consistency, and improved quality and safety. However, it is essential to understand the differences between MDSAP and traditional audits to determine which approach best suits a manufacturer's needs.

Traditional audits are conducted by a single regulatory authority and focus on that authority's specific requirements. In contrast, MDSAP is a collaborative effort between multiple authorities and covers a broader range of regulatory requirements. Traditional audits may be more flexible in terms of scheduling and scope, while MDSAP audits are conducted according to a standardized process and timeline.

MDSAP vs. Traditional Audits: Key Differences

Aspect MDSAP Traditional Audits
Regulatory authorities Multiple (Australia, Brazil, Canada, Japan, and the United States) Single (specific to each authority)
Scope Standardized, covering ISO 13485:2016 and relevant regulations Variable, depending on the authority and manufacturer's products
Audit process Standardized, with a defined timeline and process Variable, depending on the authority and manufacturer's needs

As the medical device industry continues to evolve, so too do the regulatory requirements and audit processes. MDSAP represents a significant shift in the way medical device manufacturers are audited, offering numerous benefits in terms of reduced burden, enhanced consistency, and improved quality and safety. By understanding the MDSAP program and its differences from traditional audits, manufacturers can make informed decisions about their regulatory strategies and ensure compliance with the relevant requirements.
