What is the definition of a sentinel event in a healthcare setting?

A sentinel event in a healthcare setting is characterized as an unexpected occurrence that involves death or serious physical or psychological injury. This definition is crucial because it highlights the severity and implications associated with these events, which are considered significant indicators of potential underlying problems within the healthcare system. Sentinel events signal that there may be a failure in safety protocols or procedures that need immediate attention to prevent recurrence and improve patient safety.

By identifying and addressing sentinel events, healthcare organizations can learn from these incidents. This process promotes a culture of safety and aims to enhance overall patient care quality. It is important to recognize that these events require thorough investigation and analysis, as they can reveal critical flaws in processes that could affect other patients as well.

Understanding this definition also helps in differentiating sentinel events from other types of incidents, such as minor errors that have no effect on patient care, routine incidents that may require reporting without significant consequences, or scheduled reviews of patient outcomes that are part of normal quality assurance activities.
