When it comes to pharmaceutical manufacturing, ensuring a strong quality culture is one way to avoid recurring GMP issues, such as data integrity. Susan Schniepp, Distinguished Fellow at Regulatory Compliance Associates, and 2022 PDA Board of Directors Chair outlined the evolution of current quality culture initiatives and showcased some tools to help organizations build quality culture into GMP manufacturing operations during the Nov. 11, 2021, Redica Systems Quality Week webinar, “Past, Present, and Future of Quality Culture.”
“I think that is what we see sometimes in our industry,” she said. “We do not remember how we got some of the regulations that exist today, and we repeat our past mistakes.”
From Quality Metrics to Quality Culture
Schniepp began her presentation with a look at how quality culture evolved from the early 2010s discussion on quality metrics. Key points included the following:
- On Oct. 5, 2005, CDER Director Janet Woodcock directed pharma manufacturers to build “a maximally efficient, agile, flexible pharmaceutical manufacturing sector that reliably produces high quality drug products without extensive regulatory oversight.” This set in motion CDER’s emphasis on quality in manufacturing.
- Then, in 2012, the U.S. Congress passed the FDA Safety and Innovation Act (FDASIA). Title VII of the Act allows for risk-based inspection of manufacturing sites, including requesting records in advance, or in lieu of an inspection. Additionally, the Act requires the FDA to provide Congress with an annual report on the state of drug shortages.
- Around the same time that FDASIA became effective, drug shortages became a critical concern for the agency. Schniepp pointed to aging facilities as one reason for shortages. “Tangential to metrics and quality culture, we had aging facilities, i.e., facilities producing many of the drugs showing up on the drug shortage list were degrading and not being maintained.” Quality issues at these sites had become apparent and potentially causing shortages.
- In 2014, FDA proposed implementation of a quality metrics system to encourage adoption of quality-supporting practices.
GMP Manufacturing & Measuring Quality Culture
The quality metrics push resulted in a series of conferences by ISPE, PDA, and the Brookings Institution (Figure 1 below).
“One of the elements that came out of all of these discussions was the fact that you could request any metrics that you wanted. What FDA proposed initially was rejection rate on batches, CAPA rates, etc., but the conversation became that without the culture of the organization being assessed, you could not really count on the data. So, that is how [quality metrics and quality culture] tie together,” Schniepp explained.
“You needed to have a functioning, efficient, quality metric system that gives you reliable data. And you have to count on the integrity of the culture of an organization in order to have confidence in the data that it sends you. Off of that, the discussion turned to, ‘well, how do you measure quality culture?’”
GMP Manufacturing & Quality Culture Behavior
Schniepp was part of a PDA team studying the relationship between quality culture behavior and mature quality attributes to see if there was a set of mature quality attributes that could serve as a surrogate for quality culture behaviors (ISPE has also done work in this area).
“’Mature quality attribute’” refers to “those things in your quality management system (QMS) such as your CAPA program, your change control, your investigations procedures, how you report deviations, how you record batch rejection rates, i.e., all of those things are in your quality culture or in your QMS.”
But her team wanted to know if mature quality attributes related to the behaviors of employees and management correlated with company culture, such as do people feel comfortable speaking up, do they talk to management about their concerns, do they understand their jobs, etc. The team’s research resulted in what Schniepp refers to as “the Culture Equation” (Figure 2).
“The foundation of this is quality attributes that are quantifiable and easily measured, provided they equal quality behaviors,” she said. “In other words, you have attributes reflected in your behaviors that then define your quality culture. So, if quality cultures equal quality behaviors equals quality culture, your quality attributes equal quality behaviors equal quality culture. If you can measure your quality attributes, you can define your quality culture.”
By surveying PDA’s membership, her team gathered enough data to conduct statistical analysis and was able to determine there is a relationship between quality culture behavior and quality attributes. They then worked with another team from the University of Saint Gallen’s operational excellence program. That team also found a correlation confirming “quality attributes equal quality behaviors equal quality culture.”
The PDA and St. Gallen research resulted in the PDA Quality Culture Guided Assessment Tool, addressing five key areas in which companies should focus in order to build quality culture: Employee Ownership and Engagement, Continuous Improvement, Technical Excellence, Leadership Commitment, and Communication and Collaboration. This tool is currently under development as a PDA standard.
Quality Metrics, Data Integrity & Quality Culture
Data integrity is increasingly connected with quality culture. In the PIC/S guidance, Good Practices For Data Management And Integrity in Regulated GMP/GDP Environments, “they have defined quality culture, and they have given us a little bit of information about how management can create a work environment—a culture—that is transparent and open.”
Schniepp also pointed to three other documents:
- UK MHRA GxP Data Integrity Definitions and Guidance for Industry
- WHO Guidance on Good Data and Record Management Practices
- FDA guidance Data Integrity and Compliance With Drug CGMP Questions and Answers
“In their regulations, regulators are starting to define and link culture to data integrity violations,” she explained.
She then provided a real-life example of a data integrity violation caused by a company’s culture.
“This one is kind of an interesting one because it was really an attempt by management to encourage employees to do a good job, but what they did created integrity violations.”
A contract manufacturing organization (CMO) set a GMP manufacturing goal to release batch records to clients within 30 days of manufacturing the product. To encourage this, management dangled the carrot of a pizza party at the end of the year if this goal was met. In order to meet this goal, employees released batch records to clients even if investigations had not uncovered the root cause. Investigations would be prematurely closed and then reopened after the batch record had been sent to the client.
“That, in and of itself, is a data integrity nightmare,” Schniepp said. “Can you imagine explaining in an audit by a regulator, ‘well, we wanted a pizza party?’”
GMP Manufacturing & Organizational Culture
Regarding deviation investigations, she told another story of a company for whom she worked that involved repeat observations. When reviewing deviations, she found that one operator had 30 deviations tied to him involving a specific product. This operator failed to sign the batch record during a specific point in time in manufacturing. His managers kept retraining him.
[Author’s Note: Additional information about deviation investigations can be found in the articles, “GMP Inspection Case Study Focuses on Inadequate Deviation Investigations” and “How to Avoid Three Common Deviation Investigation Pitfalls.”]
In talking with the operator, Schniepp learned that in order for the operator to sign the batch record (according to GMP regulations at that particular point in manufacturing), the operator had to leave the product alone in the equipment, de-gown, sign the batch record, re-gown, and return, all the while hoping the product was okay. Out of concern for the product, the operator chose to stay behind and try to remember to sign the batch record once he was done.
“It was a poorly designed batch record process,” she said. But the operator did not feel listened to when he brought his concerns to management.
Schniepp then pointed out that other employees worked on the product under the same cGMP constraints. So, what were these other employees doing? How many other data integrity violations occurred? Was GMP labelling reviewed accurately?
“Nobody else was bringing it up. If you do not have that open culture, if you are not encouraging people to speak up and you are not listening to them, you do not have a good quality culture.”
The Future is GMP Manufacturing Quality
For further evidence of the importance of GMP certification and quality culture, Schniepp reviewed a 483 observation issued in 2019 with numerous examples of data mismanagement. The company in question then responded to FDA with a letter promising to ensure a robust quality culture going forward. [Author’s Note: For more about this GMP compliance incident, read the first case study in the article, “Data Integrity Concerns Discovered in Gene Therapy Product Submissions,” by Jerry Chapman.]
Schniepp believes this 483 observation shows FDA’s intent to heavily focus more on good manufacturing practices in future inspections. This means companies must develop or enhance their quality culture when thinking about how to prepare for upcoming inspections.
“I believe we will see more of this,” she said. “More companies will be looking at their GMP manufacturing and trying to improve the Quality Culture.”
Otherwise, as she explained at the beginning of her presentation, companies who remain in the past when it comes to cGMP certified practices that lead to quality culture face the prospect of 483 observations, Warning Letters, and other negative outcomes.
