Understanding Root Cause Analysis
Think of any clinical problem as the tip of an iceberg—what you see on the surface rarely tells the whole story. When issues occur in healthcare, whether it’s a medication error, care delay, or unexpected event, our natural instinct is to address the immediate symptom. However, this surface-level approach often fails to prevent recurrence.
The 5 Whys framework provides a systematic method for exploring what’s happening beneath the surface. By asking “Why?” five or more times, with each answer forming the basis of the next question, teams can move from obvious, individual-focused explanations to the systemic root causes that drive recurring problems.
The goal isn’t to find someone to blame, but rather to identify processes that can be fixed to create safer, more reliable care systems.

Getting to the Root Cause with the 5 Whys
This foundational video demonstrates how to systematically apply the 5 Whys framework using a real clinical scenario. Brenda Fahy, MD, Professor and Associate Chair of Faculty Affairs and Professional Development for the Department of Anesthesiology at the University of Florida and the Physician Director for Quality for Critical Care at Shands Hospital, walks through a medication error case, showing how each “Why?” question moves the investigation from individual blame toward systemic solutions.
Watch this video to understand both the mechanics of the 5 Whys process and its collaborative approach to sustainable problem-solving.
Transcript: Getting to the Root Cause with the 5 Whys
Hello, my name is Brenda Fahy, and I currently serve as the Professor and Associate Chair of Faculty Affairs and Professional Development in the Department of Anesthesiology, and I am the Physician Director for Quality for Critical Care at Shands Hospital.
In a clinical setting, when a problem occurs—a delay in care, a medication error, or an unexpected event—our first instinct is to fix what’s right in front of us. But addressing the immediate symptom often does not prevent the problem from happening again.
To create lasting solutions, we need to go deeper. The 5 Whys is a simple but powerful root cause analysis tool that helps teams move beyond the obvious surface-level issues to uncover the systemic problems that are truly the driving issue.
Think of any problem as the tip of the iceberg. The 5 Whys framework is your method for exploring what’s happening beneath the surface. It’s an investigative technique where you and your team ask the question “Why?” five or more times, with each answer forming the basis of the next question… the next “Why?”
Let’s walk through a common clinical scenario. In this case, a patient in the intensive care unit who received the wrong dose of an antibiotic.
Now, let’s ask why. The first Why is that the nurse administered an incorrect dose.
Please note that this is a surface-level finding. It’s easy to stop here, but it leads to a culture of blame and does not solve the underlying issue. Let’s ask why the incorrect dose was administered.
Why 2? The medication was dispensed incorrectly from the pharmacy’s automated dispensing cabinet.
Why 3? The pharmacy technician restocked the cabinet with the wrong concentration of the antibiotic.
Why 4? Two different concentrations of the same antibiotic have look-alike packaging and were stored side-by-side in the same bin.
Now we’re getting somewhere. This is a system issue, not just an individual error. Let’s ask why one more time.
Why 5? The hospital does not have a formal policy for physically separating look-alike, sound-alike medications with different strengths.
This final Why leads us to the root cause. Fixing this will prevent this type of error from recurring, regardless of the individuals involved. After all, the goal is to find a cause that, if addressed, will prevent the problem from happening again. This is the litmus test for a true root cause. It’s not about finding someone to blame; it’s about finding a process to fix.
Keep in mind that the 5 Whys should be explored collaboratively. By asking these questions together, your team can develop a shared understanding of the problem and co-create a solution that will stick.
So, remember, use the 5 Whys to move past the indicators of a problem and build a safer, more reliable system of care.

The resource walks you through the four-phase process:
- Assembling the right team and defining a blame-free problem statement
- Asking “Why?” repeatedly to drill down through layers of causation
- Identifying when you’ve reached the true root cause
- Validating your findings with the litmus test
