Sentinel events

What is a sentinel event?

A sentinel event refers to unexpected occurrences involving death or serious physical or psychological injury or risk thereof. Sentinel events represent 10 specific types of clinical incident. They are:
  1. Surgery or other invasive procedure performed on the wrong site resulting in serious harm or death
  2. Surgery or other invasive procedure performed on the wrong patient resulting in serious harm or death
  3. Wrong surgical or other invasive procedure performed on a patient resulting in serious harm or death
  4. Unintended retention of a foreign object in a patient after surgery or other invasive procedure resulting in serious harm or death
  5. Haemolytic blood transfusion reaction resulting from ABO incompatibility resulting in serious harm or death
  6. Suspected suicide of a patient in an acute psychiatric unit or acute psychiatric ward
  7. Medication error resulting in serious harm or death
  8. Use of physical or mechanical restraint resulting in serious harm or death
  9. Discharge or release of an infant or child to an unauthorised person
  10. Use of an incorrectly positioned oro- or naso-gastric tube resulting in serious harm or death

Further description of the 10 sentinel event categories can be found in the Clinical Incident Management Policy (external site).
