Effective Internal Audits for Medical Device Firms

Internal audits are a critical activity for every medical device firm. Not only are they mandatory per 21 CFR 820.22 and Clause 8.2.4 of ISO 13485:2016, but they are also fundamental in ensuring continuous review and improvement of a quality management system. Although there are numerous positive outcomes of an effective internal audit, it can be a daunting task if not implemented correctly. Medical device firms should strive to not only satisfy the regulatory requirement for internal audits but use them as a continuous improvement tool.

The very first step in ensuring effective internal audits is implementing a robust audit management program in your QMS. Your program should include the scope of regulations (i.e. ISO, FDA, etc.), an audit schedule with rationale, what qualifications are necessary for the personnel conducting the audits, and any other fundamental pieces that will facilitate conducting the internal audits. The regulatory requirements for internal audits are generally vague, just saying that you shall conduct them at planned intervals and use them to assure your quality system is effective and in compliance with established requirements.1 This creates a critical gray area for many med device firms, leaving it up to them to determine how often to conduct internal audits and what the process looks like. Creating an effective audit schedule should be the major first step in your audit management program. Determining what frequency, you should conduct audits on what processes will help you create and justify this schedule; for many small start-ups, a once annual internal audit may be sufficient, while for larger firms, it may require quarterly.

A signature trademark of an effective internal audit is being more thorough than the FDA. Internal audits are the time to catch and correct any compliance risks and make sure your QMS is prepared for a regulatory inspection. Firms should draft audit checklists within the bounds of their audit scope (i.e. what regulations you are auditing against). Within these checklists, there should be processes to be checked off, which are then broken down into a list of relevant procedures, and then even further broken down in a sampling of records. If your checklists take high level processes and break them down into their individual components and records, you can ensure that you’ve captured everything.

Any findings that come out of your internal audit should be analyzed and reported on to management, typically during management review at a minimum. Findings should translate into CAPA’s, which act as inputs to improve the QMS. All medical device firms should be conducting internal audits not only because it satisfies a regulatory requirement, but also because they can act as great continuous improvement tools.

De Novo Classification

A device can be registered for the De Novo pathway if there is evidence of the safety and effectiveness of the device and there is not a previously legally marketed predicate device1. When determining if your device can go through the De Novo process there are two pathways available to determine the device classification.

Abbreviated 510k submission

There are three types of 510K, Premarket Notifications, which can be submitted to the Food and Drug Administration (FDA) traditional, abbreviated, and special. Abbreviated and Special 510K submissions can be utilized when the submissions meet the certain factors presented by the FDA. When submitting an abbreviated 510K the submission must include the elements that are identified in 21CFR 807.87 for the information required in a premarket notification submission.
Is your product a medical device?

Is your product a medical device?

Many marketed products are classified as medical devices and you would not even know it. Medical devices range from latex gloves and tongue depressors to respirators and heart valves. To determine if the product is considered a medical device by the Food and Drug Administration (FDA) you will need to analyze if your product meets the definition of a medical device per the Food, Drug, and Cosmetic Act1.
