The United States Food and Drug Administration (FDA) regulates the medical device industry to ensure the safety and effectiveness of medical devices used by healthcare professionals and patients. As part of their regulatory oversight, the FDA conducts inspections of medical device manufacturing facilities to assess compliance with applicable regulations. When significant deviations from compliance standards are identified, the FDA issues a document called FDA Form 483. This article will explore what FDA Form 483 is, its significance, and how medical device manufacturers can address compliance issues effectively.

What is FDA Form 483?

The FDA Form 483, officially known as “Notice of Inspectional Observations,” and commonly referred to as “483” is issued at the end of an on-site inspection of regulated facilities by the FDA field investigator in response to deficiencies in the quality system or conditions that violate the Food, Drug, and Cosmetic Act.

An FDA Warning Letter may be issued if the manufacturer has significantly violated FDA regulations, or if the manufacturer’s response to the 483 is deemed insufficient. Warning letters are an escalation for Form 483 and may lead to regulatory action if not addressed and resolved properly.

The 483 does not represent an FDA determination of violations; it is intended to guide corrective actions to be taken by the manufacturer based on inspection. When a manufacturer receives a 483, they must respond quickly to correct the issue to avoid a warning letter. The FDA 483 form serves as a tool to assist manufacturers in understanding and correcting compliance issues and is the starting point of communication between the FDA and the facility.

The most common observations that appear on the 483 are:

  • Inadequate of Insufficient Standard Operating Procedures, testing or quality control
  • Inadequate training of personnel to relevant procedures of quality control measures
  • Inadequate or insufficient investigation to correct deviations or complaints
  • Lack of or inadequate validation of processes or equipment
  • Inadequate or insufficient testing of products or raw materials.
  • Failure to properly handle, store, or label materials
  • Failure to establish or maintain adequate records or logs
  • Failure to properly report adverse events
  • Failure to follow established procedures or protocols.

The 483 is not intended to be an all-inclusive list of every deviation from law and regulation. The 483 may not capture all objectionable conditions present at the company. FDA investigators are instructed to document only what they observe during inspection. Companies need to take responsibility for identifying and addressing both the cited objectionable conditions and any additional non-cited objectionable conditions that may exist.

After the Inspection

After the inspection is complete, the lead inspector(s) will meet with the manufacturer to discuss the findings, provide feedback, and share observations. The manufacturer should review the findings, make corrections if possible and describe next steps.

The lead inspector will prepare a written report and submit it to FDA headquarters for evaluation. The final written FDA report is known as the Establishment Inspection Report (EIR) and is available approximately 3-6 months after the inspection. It is also available to the public through the Freedom of Information Act (FOI).

The manufacturer must respond to the 483 or Warning Letter within 15 days of receipt and provide the summary of all correction action plans and timelines. A detailed response to each observation or violation is required.

Responding to FDA Form 483

The manufacturer must provide a detailed response to each observation or violation, indicating:

  • Why the product(s) are still safe and effective
  • Analyze the Findings of the 483 and/or Warning Letter and determine if the observations by the inspector(s) impact the safety and effectiveness
  • Any evidence which demonstrates that the inspector’s observation was incorrect and not fully accurate
  • Develop a corrective action plan and course of action for addressing the observed issue(s), identify specific remediation appropriate for each observation
  • Documentation of actions that have been taken since the FDA form 483 was received.
  • Suggest an appropriate timeline to satisfy the FDA

How to avoid FDA 483 citations

Always be “inspection ready” by ensuring the Quality Management System is compliant to the regulations.

  1. Develop and maintain a robust QMS
  2. Effectively manage employee training
  3. Conduct Internal Audits
  4. Monitor and control the supply chain
  5. Respond appropriately to issues that arise
