Root Cause Analysis and Problem-Solving Tools
In clinical research, maintaining accurate data and ensuring patient safety requires more than just noting a protocol deviation after it happens. It demands finding out exactly why the failure occurred so you can stop it from happening again.
By utilizing the three structured root cause analysis tools below—Is/Is-Not Analysis, the Fishbone Diagram, and the 5 Whys—your study team can move past surface symptoms, isolate process gaps, and uncover the true origin of any clinical error.
Using these visual tools ensures your site designs highly targeted corrections, protects trial integrity, and stays entirely prepared for sponsor audits or regulatory inspections.
Root Cause Analysis Training
Before you can fix a problem, you must define its exact boundaries. This tool helps your team compare what the issue is against what it is not.
- Isolate the Issue: It stops your team from wasting time on unrelated systems.
- Clinical Example: Finding that a data entry error happens only on the electronic diary (Is) but never occurs on the paper source document (Is Not) allows you to target the exact fix instantly.
A fishbone diagram is a visual tool used to identify and organize potential root causes of a specific problem.
The primary goal of a fishbone diagram is to help teams look beyond obvious symptoms and identify root causes of an issue.
This is a simple but powerful technique used to drill deep down into a problem.
- Dig Deeper: By asking "Why?" five times in a row, your team moves past the immediate surface symptom.
The Goal: It helps you trace a clinical error back to its actual origin point so you can fix the system, not just the symptom
Document
A CAPA (Corrective and Preventive Action) template can be used to document any process error, compliance issue or deviation.
The CAPA template will guide you through the following process.
Description of the problem
Investigate and identify root cause (Use of Root Cause Analysis tools)
Corrections to address the immediate problem
Preventive actions to prevent problem from occurring again
