Sentinel events are defined by the The Joint Commission (TJC) in the USA as, "any unanticipated event in a healthcare setting resulting in death or serious physical or psychological injury to a patient or patients, not related to the natural course of the patient's illness. Sentinel events specifically include loss of a limb or gross motor function, and any event for which a recurrence would carry a risk of a serious adverse outcome."

These events include, "unexpected occurrences involving death or serious physical or psychological injury, or the risk thereof" and all of the following, even if the outcome was not death or major permanent loss of function:

• Infant abduction, or discharge to the wrong family.
• Unexpected death of a full-term infant.
• Severe neonatal jaundice (bilirubin over 30 milligrams/deciliter).
• Surgery on the wrong individual or wrong body part.
• Instrument or object left in a patient after surgery or another procedure.
• Rape in an acute-care setting.
• Suicide in an acute-care setting, or within 72 hours of discharge.
• Haemolytic transfusion reaction due to blood group incompatibilities.^[1]
• Radiation therapy to the wrong body region or 25% above the planned dose.

The clinical laboratory organisation, Dark Daily suggest that this list should also include 'misdiagnosis' and other preventable diagnostic errors.

Diagnoses that are missed altogether, wrong, or should have been made much earlier

An AVM or arteriovenous malformation forms when arteries connect directly to veins. This direct connection forms a high-pressure shunt or fistula. The veins are not able to handle the pressure of the blood coming directly from the arteries. The veins stretch and enlarge to create a “nidus”. Usually there are multiple feeding vessels in an AVM and many draining veins.
