What is a sentinel event in healthcare?

A sentinel event in healthcare is defined as an unexpected occurrence that involves death or serious physical or psychological injury. This definition highlights the gravity of the event and underscores the need for immediate investigation and response. Sentinel events serve as critical indicators of systemic issues within healthcare systems that necessitate changes to prevent future occurrences. By identifying and analyzing sentinel events, healthcare organizations can improve patient safety and quality of care.

The definition emphasizes the unexpected nature of these events, which makes them particularly alarming and necessitates a thorough examination to understand the underlying cause. The focus on serious outcomes also differentiates sentinel events from less critical incidents, which may not warrant such immediate and in-depth investigation. Understanding sentinel events helps healthcare practitioners recognize situations that require a heightened level of response and change in practice.
