Reporting sentinel events to The Joint Commission began in 1996 as a way to help health care organizations improve safety. The annual review is based on an aggregate database of reports analyzed each year, according to the review authors.
The Joint Commission defines a sentinel event as a patient safety event (not primarily related to the natural course of the patient’s illness or underlying condition) that reaches a patient and results in death, permanent harm (regardless of severity), or severe harm (regardless of duration).
Some of the specific events deemed sentinel include patient suicide while under care in a health care setting, unanticipated death of a full-term infant, homicide of any patient or staff member while on site at a health care organization, any intrapartum maternal death, severe maternal morbidity, sexual abuse or assault of any patient undergoing care in the health care setting, sexual abuse or assault of any staff member providing care, and physical assault of any patient or staff member in the health care setting.
Additional events considered sentinel are related to treatments and procedures. These include surgery in the wrong site; wrong patient or wrong procedure for a given patient; administration of blood or blood products incompatible with the patient that results in death, permanent harm, or severe harm; severe neonatal hyperbilirubinemia; and patient falls.
A total of 1,441 sentinel events were reported in 2022. Patient falls accounted for the majority (42%) of these events, continuing a trend in increasing rates of patient falls from previous years. Falls considered sentinel events were those resulting in any fracture, surgery, casting or traction, consultation or comfort care for neurologic or internal injury, the need for blood products, or death or permanent harm as a result of injuries sustained in the fall. The leading sentinel event types after falls included delay in treatment, unintended retention of a foreign object, and wrong surgery (6% for each). Other sentinel event types in the top 10 accounted for 5% or less of reports: suicide (5%), assault/rape/sexual assault/homicide (4%), fire/burns (3%), perinatal events (2%), self-harm (2%), and medication management (2%).
Overall, 20% of the 2022 events resulted in patient death, 6% in permanent harm or loss of function, 44% in severe temporary harm, and 13% in a need for additional care or an extended hospital stay.
The most common events that led to patient death were suicide (24%), treatment delays (21%), and patient falls (11%). Patient falls also accounted for nearly two-thirds of the events resulting in severe temporary harm (62%).
Most of the events (88%) occurred in hospital settings; of these, the most common were falls (45%), followed by the retention of foreign objects and incorrect surgeries (7% and 6%, respectively). Overall, 90% of sentinel events were reported by the health care organizations; the remaining 10% were reported by patients, families, or employees (current or former).
“Failures in communication, teamwork, and consistently following policies were leading causes for reported sentinel events,” the authors wrote. However, reporting sentinel events is voluntary; therefore “no conclusions should be drawn about the actual relative frequency of events or trends in events over time,” they noted.
