The Truth Behind Human Error – An In-Depth Investigation into Pitfalls in the Pharmaceutical Industry

Understanding Human Error

While human errors are inevitable in a dynamic environment, they are particularly critical in the pharmaceutical sector due to their potential to have a harmful impact on patients. These errors can have various causes, ranging from cognitive limitations and insufficient training to communication breakdowns and design flaws in processes and systems.

The Categories of Human Errors

First and foremost, it is of the utmost importance to understand the different categories of human errors. By gaining insight into the underlying causes of these errors, we can integrate strategies to reduce them into the corporate culture and procedures.

Below, we list the categories of human error:

1. Learning errors: These occur when individuals lack the necessary skills, knowledge, or a sufficient understanding of the consequences of their actions. Ongoing training and education are essential to reducing learning errors.
2. Memory errors: Sometimes people know what needs to be done but forget it when the situation calls for it. Memory aids, checklists, or reminders can help reduce memory errors.
3. Inconsistency errors: When people know the correct method or standards but vary in their approach, inconsistency can lead to unpredictable results. Establishing clear procedures and guidelines is crucial to reducing inconsistency errors.
4. Application errors: Knowing the correct procedure but applying it incorrectly can lead to errors, incorrect results, or carryover errors. Implementing verification processes and double-checks can be effective in preventing application errors.
5. Omission errors: Omission errors occur when individuals overlook a step, action, or piece of information, which can lead to missing information, skipped steps, or the use of the wrong item. Robust procedures and thorough reviews can help prevent errors related to omissions.
6. Decision-making errors: Sometimes people make incorrect decisions given the situation or the available information, which can lead to inappropriate actions or behaviors. Promoting a culture of open communication and collaboration can reduce decision-making errors by facilitating collective decision-making and feedback.

By understanding these common categories of human error and implementing strategies to address them, organizations and individuals can significantly reduce the likelihood of errors, leading to improved efficiency, safety, and overall performance within the corporate culture.

Control Hierarchy for Human Errors

Human errors can occur in any workplace, but they are often symptoms of an underlying problem. Understanding the root causes of these errors is crucial for implementing effective management strategies. Below, we explore a structured approach to managing and reducing human errors. Let’s take a closer look at the hierarchy of management strategies:

1. Error-proofing: eliminating the possibility of human error

At the top of our hierarchy is “error-proofing,” the gold standard for preventing human errors. This approach, also known as Shutout Poka-Yoke, focuses on making it physically impossible to proceed if a step is skipped or performed incorrectly. It’s all about designing systems and processes in a way that leaves no room for error.

Consider, for example, a printing system with a verification camera that automatically identifies and rejects aerosol cans or bottles with labeling errors, thereby reducing the need for error-prone, manual checks of variable data.

2. Error Prevention: Encouraging Attention to Prevent Errors

Next, we have error prevention, a proactive approach aimed at detecting errors before they occur. Often referred to as “Warning Poka-Yoke,” this strategy uses devices or systems that alert users to potential errors. These warnings provide immediate feedback and help people correct their actions before errors can escalate further.

Consider, for example, the use of color-coded labels and packaging to distinguish between different medications and dosages. This helps healthcare providers and patients quickly identify the correct medication and reduces the risk of errors.

3. Error resilience: providing a safety net for errors

Error-proofing revolves around creating systems that allow people to correct errors before they cause harm. It acknowledges that errors can still occur despite the best preventive efforts. In such cases, mechanisms for quickly correcting errors can be invaluable.

For example, consider conducting a reconciliation to confirm the correct use of all essential materials in the production process. This is essential for preventing mix-ups and minimizing their adverse consequences during production.

4. Redundancy Measures: The Last Line of Defense

Finally, there are redundancy measures, which serve as the last line of defense against errors that manage to bypass earlier safeguards. These measures involve duplicating efforts or resources to reduce the potential impact of errors.

Consider, for example, the “two-person rule” for critical steps, whereby two authorized individuals must independently verify and document each part of the process. Or, for instance, backup systems and contingency plans. These measures can help limit the consequences of an error and keep a situation under control if all other measures fail.
