10 FDA Inspection Strategies that DON’T Work

You were just notified of an FDA inspection and don’t think you are ready; using tricks to hide your problems is a huge mistake. Over the years, I have heard a few recommendations for “secrets” to hide those problems. In this post, I share my top 10 FDA Inspection Strategies–and why they DON’T work.

Here are my top 10 ways to make an FDA inspection worse:

10. Stalling when the investigator makes a request – This just irritates investigators. At best, the investigator will use the waiting time to identify additional documents to sample or to review the information you have provided more closely. At worst, the investigator will accuse the company of not cooperating with the inspection, and the investigator may return the following week with several more team members to help them. Whenever this occurred during a third-party audit that I conducted, I would move onto another area and interview someone. However, before I left the person that was slow to respond, I provided the person with a list of documents and records that I expected to be waiting for me upon my return. In extreme cases, I had to bluntly tell the management representative that I needed documentation more quickly. As an instructor, I teach auditors techniques for coping with this tactic.

9. Suggesting records for the investigator to sample – This is forbidden in third-party inspections and audits. The FDA has work instructions for identifying sample sizes, and samples are supposed to be selected randomly. In reality, samples are rarely random, and the investigator usually follows a trail to a specific lot, part number, etc. When clients offered me samples, I tried to be polite and review the records they provided. However, I also would request several other records or follow a trail, as I have indicated above. Another approach I often use is to focus on high-risk items (i.e., – a risk-based approach to sampling). In general, you can expect the FDA investigators to sample more items than a registrar–and sample sizes are often statistically derived if the number of records is sufficiently large. When sample sizes are pretty small, I recommend sampling 100% of the records since the previous inspection/audit. This is not always possible for third-party auditors, but internal auditors often can achieve this.

8. Outsourcing processes to subcontractors – The FDA recently reinstated the requirement for contract manufacturers and contract sterilizers to be registered with the FDA by October 1, 2012. Therefore, hiding manufacturing problems from the FDA by outsourcing manufacturing is increasingly more difficult. In addition, the FDA focuses heavily on supplier controls and validation of outsourced processes. Therefore, an investigator will identify high-risk processes performed by subcontractors and request process validation documentation from that supplier. If the company does not have the validation reports, this could quickly escalate to a 483 and possibly a visit to the subcontractor.

7. Trying to correct problems during the inspection – This is what I like to call the document creation department. At one company I worked for, we noticed a mistake across several of the procedures and made a change overnight between the first and second days of the audit. When the auditor asked for the procedures in the morning, he asked, “Is the ink dry yet?” The auditor then requested records demonstrating compliance with the newly minted procedures. As you might have guessed, this resulted in several nonconformities. When clients attempt to correct problems found by an investigator, the investigator typically will respond with the following statement, “I applaud you for taking immediate action to contain and correct the problem. However, you still need to investigate the root cause and develop a corrective action plan to prevent a recurrence. To do this investigation properly may take several days.” I also teach auditors to memorize this phrase.

6. Writing a letter to file – When companies make minor design changes, one of the most common approaches is to “write a letter to file.” This phrase indicates that the design team is adding a memo to the Design History File (DHF) that justifies why design validation or regulatory notification/approval is not required. The FDA used to publish a decision tree to help companies make these decisions. In fact, such a decision tree is still part of the Canadian significant change document. The FDA recently withdrew a draft document that eliminated many perceived opportunities to utilize the “letter to file” approach. However, the FDA will still issue a 483 to a company if the investigator can identify a change that required validation that was not done or a 510(k) that was not submitted for a design change. The FDA looks explicitly for these types of issues when an investigator is doing a “for cause” inspection after a recall or patient death.

5. Shut it down – Not running a production line that has problems is an ideal strategy for hiding problems. However, the FDA and auditors will be forced to spend more time sampling and reviewing records of the problematic production line. If you need to shut down a line, ensure everything is identified as non-conforming, and carefully segregate rejected products from good ones. You should also use these problem lines to show off your investigation skills and ability to initiate CAPAs. If you simply forgot to validate a piece of equipment or do some maintenance, take your lumps and keep production running. If you are a contract manufacturer, never shut it down without notifying the customer. If you do not tell your customer, you will get a complaint related to on-time delivery and a 483.

4. Storing all records off-site – I first heard about this tactic during an auditor course I was co-teaching. During the course, we had many reasons why the company should be able to provide the records in a timely manner. However, I have experienced this first-hand as a third-party auditor. When this happens, I do three things: 1) increase my sampling of available records, 2) carefully review supplier controls and supplier evaluation of the storage facility (assuming it is outsourced), and 3) verify that the company has a systematic means for tracking the location (i.e., – pallet and box) for every record sent to storage. FDA investigators will move along to another record and follow up on their earlier request with a second visit or a request to send them a copy of the document after the inspection.

3. Identifying information as confidential—A company can claim information is confidential and may not be shared with the public. Still, very little information concerning the FDA or Notified Bodies is “confidential.” Therefore, this strategy rarely works. In fact, it will enrage most FDA investigators. In training courses, I train auditors to ask the auditee to redact confidential information. For example, a CAPA log may have confidential information in the descriptions, but the trend data on opening and closing dates are never confidential.

2. The FDA is not allowed to look at those records – Although this statement is technically true for internal audit reports and management reviews, the FDA always says that they can access this information through the CAPA system. What the FDA means is that there should always be evidence of CAPAs from internal audits and management reviews. If there is not, then this will quickly become a 483. Another person I met tells the story that when they agreed to share the management review records with the investigator, the inspector rarely issued a 483. When they refused to share the management review with the FDA, the inspection went quite badly from that point forth. I’m afraid I have to disagree with being vindictive, but it happens.

1. Show me where that is required – This is just silly. Investigators and auditors are trained on the regulations, while you are educated on your procedures. Spend your time and effort figuring out how your procedures meet the regulations in some way. Challenging the investigator excites the investigator. We all like a challenge–and we rarely lose. One auditee tried this approach with me in front of their CEO. This experience allowed me to show off that I had memorized the clause in question–and the corresponding guidance document sections. I think the CEO realized quickly that the management representative was not qualified.

My final advice is to do your best to help the investigator do their job and treat every 483 as “just an opportunity to improve.” Just ensure you submit a response in 14 days, or you will receive a Warning Letter, too!
