483 Response: Which corrective action plan should you write first?

Article explains how to determine which FDA Form 483 response you should write a corrective action plan for first and why.

In a perfect world, you would not receive any inspection observations from your next FDA inspection. However, most companies get at least one observation resulting from an FDA inspection and often there are multiple observations on an FDA Form 483. If you

Most Common FDA 483 inspection observation

Companies that have not experienced an FDA inspection before worry too much and prepare too little. Inspections are predictable and certain inspection observations are much more common than others. A couple of years ago I wrote an article analyzing the most common FDA inspection observations. The most common observations are specific to design controls (i.e., 21 CFR 820.30). However, this fact is distorted because many companies receive multiple observations during the same inspection related to design controls. For example, a client of mine recently received three from one inspector: 1) lack of design reviews, 2) lack of design validation, and 3) lack of risk analysis. All three were found during the review of the same design history file and the one corrective action addresses all three observations.

2nd Most Common FDA 483 inspection observation

The second most common observation is specific to corrective and preventive actions (i.e., 21 CFR 820.100). Typically the company has inadequate procedures for verifying and validating effectiveness of corrective actions taken. If this is one of your FDA 483 observations, then you may have a problem with CAPA training or with the design of your CAPA form. If there is no place on the CAPA form to document your effectiveness check, then you might easily forget to perform the verification and validation of effectiveness. Another possibility is that personnel are confused between verification of implementation and the verification of effectiveness.

What if you have multiple FDA 483 observations?

Other common FDA 483 observations include medical device reporting, complaint handling and rework of nonconforming product. If you receive more than one FDA 483 inspection observation, you need to assume there is a chance that the inspection outcome will be “Official Action Indicated” (OAI). In this case, you need to provide a 483 response to your FDA district office within 15 business days. With such a short time to prepare your 483 response, you need to be efficient. Which 483 response should you initiate first and why?

If one of the inspection observations is related to the CAPA process, that 483 response should be your top priority. The reason for this is that the FDA will want to see objective evidence of implementing corrective actions whenever possible. If you use your CAPA procedure and form to document the 483 response, then you can show the FDA how the revised procedure or form will be used in your 483 response. If you write your 483 response for other inspection observations first, then the other 483 responses are using the existing procedure or form that the identified as inadequate.

Your first step should always be to implement corrective actions to address an inadequate CAPA process by revising the procedure or the form. Once the procedure or form is updated, then you can use the new process to document the rest of your 483 responses.
