The process of identifying the basic causal factors and variations in performance leading to a sentinel event is known as root cause analysis. This methodology focuses on uncovering the underlying reasons for a significant incident, such as an unexpected patient safety event in healthcare. By delving into the root causes, organizations can gain insights into what went wrong and develop strategies to prevent similar occurrences in the future.

Root cause analysis employs systematic investigative techniques to examine contributing factors—whether they are process-related, human error, equipment failure, or other systemic issues. This comprehensive approach ensures that solutions address not just the superficial symptoms of the problem, but also the fundamental issues that allowed it to happen.

In contrast, failure mode effects analysis primarily focuses on potential failures in a process before they occur, while performance improvement refers broadly to efforts to enhance overall function and quality within an organization. Risk assessment is aimed at identifying potential risks and their impacts rather than diagnosing past events. Thus, root cause analysis stands out as the most appropriate process for understanding and addressing the origins of sentinel events.
