Sentinel Events in Healthcare: Definition, Examples, and Importance for Patient Safety and Quality Improvement
Overview
This paper defines sentinel events as unexpected occurrences involving death or serious injury in healthcare settings and explains their significance as indicators of quality issues. It provides two concrete examples—perioperative deaths and wrong-site surgeries—and argues that mandatory reporting of sentinel events is essential for conducting root cause analyses, implementing preventive measures, and fostering transparency and accountability in healthcare organizations.
What this essay covers

Sentinel Events in Healthcare
What a sentinel event is? Provide 2 examples of reportable sentinel events.
A sentinel event is an unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof, in healthcare settings. Serious injury specifically excludes minor or moderate harm, emphasizing events that signal the need for immediate investigation and systemic change. These events are called “sentinel” because they serve as indicators of underlying quality issues, prompting organizations to analyze root causes and implement preventive measures (The Joint Commission, 2025). Two examples of reportable sentinel events include perioperative deaths, such as a patient expiring during or immediately after surgery due to anesthesia complications, and wrong-site surgeries, where a procedure is performed on the incorrect body part, leading to potential permanent harm (Rodziewicz et al., 2024).
Why is it important for sentinel events to be reported?
Reporting sentinel events is crucial for enhancing patient safety and healthcare quality. It enables organizations to conduct thorough root cause analyses, identifying process failures and contributing factors like communication breakdowns or equipment malfunctions (The Joint Commission, 2025). This leads to targeted interventions that prevent recurrence, ultimately reducing medical errors and saving lives. Moreover, mandatory reporting fosters a culture of transparency and accountability, allowing accreditation bodies to track trends and develop evidence-based standards (Rodziewicz et al., 2024). Without reporting, opportunities for systemic improvements are lost, perpetuating risks and eroding trust in healthcare systems.
