What distinguishes a sentinel event from other types of incidents in healthcare?

A sentinel event is primarily distinguished by the severity of harm that it causes, typically resulting in death or permanent injury to a patient. This high level of severity differentiates sentinel events from other incidents in healthcare that may involve lower risk or less severe outcomes.

While legal action, chronic issues, and patient satisfaction can contribute to the healthcare environment and the management of incidents, they are not the defining characteristics of a sentinel event. Legal action may arise from various healthcare incidents, but it's not a universal component of sentinel events. Chronic issues tend to refer to ongoing problems that affect patient care over time, whereas sentinel events are specific, unpredicted occurrences. Similarly, patient satisfaction is a measure of patients' perceptions and experiences, which does not inherently correlate with the classification of events as sentinel or non-sentinel. Hence, the defining factor for a sentinel event remains its capacity to cause significant harm, primarily leading to serious outcomes for patients.
