Which of the following perioperative events is classified by The Joint Commission as a sentinel event?
Show answer & explanation
Answer: D
A sterile tray found torn and replaced before the case began: Incorrect. A packaging problem caught before use is a near miss or reportable issue, not a sentinel event, because no patient harm occurred.
A sponge count discrepancy resolved by finding the sponge in the room: Incorrect. A resolved count discrepancy is documented per policy but is not a sentinel event, since nothing was retained.
A brief delay in starting a case because of a missing instrument: Incorrect. Delays are operational problems that may be reported internally but do not meet the sentinel event definition.
Unintended retention of a sponge in a patient after surgery: Correct. The Joint Commission lists unintended retention of a foreign object after an invasive procedure as a sentinel event requiring root cause analysis.
Sentinel events include retained foreign objects, wrong-site/wrong-patient/wrong-procedure surgery, surgical fires and other events causing death or severe harm; they require a comprehensive systematic analysis.
