Never events

Never events are the "kind of mistake (medical error) that should never happen" in the field of medical treatment. According to the Leapfrog Group never events are defined as "adverse events that are serious, largely preventable, and of concern to both the public and health care providers for the purpose of public accountability."

A 2012 study reported there may be as many as 1,500 instances of one never event, the retained foreign object, per year in the United States. The same study suggests an estimated total number of surgical mistakes at just over 4,000 per year in the United States; however, these statistics are extrapolations from small samples rather than actual event counts.

United States

A list of events was compiled by the National Quality Forum and updated in 2012. The NQF’s report recommends a national state-based event reporting system to improve the quality of patient care.

1. Artificial insemination with the wrong donor sperm or donor egg
2. Unintended retention of a foreign body in a patient after surgery or other procedure
3. Patient death or serious disability associated with patient elopement (disappearance)
4. Patient death or serious disability associated with a medication error (e.g., errors involving the wrong drug, dose, patient, time, rate, preparation or route of administration)
5. Patient death or serious disability associated with a hemolytic reaction due to the administration of ABO/HLA-incompatible blood or blood products

As of 2006

, a little more than half of U.S. states have some version of a reporting system for never events.

United Kingdom

The National Patient Safety Agency produced a list of eight core never events in March 2009:

1. Wrong site surgery
2. Retained instrument postoperation
3. Wrong route administration of chemotherapy
4. Misplaced naso or orogastric tube not detected prior to use
5. Inpatient suicide using non-collapsible rails
6. Escape from within the secure perimeter of medium or high security mental health services by patients who are transferred prisoners
7. In-hospital maternal death from post-partum haemorrhage after elective caesarean section
8. Intravenous administration of mis-selected concentrated potassium chloride

NHS England produced a report on 148 reported never events in the period from April to September 2013 highlighting particular hospitals with more than one such event.

NHS Improvement has produced monthly and cumulative annual reports since 2015, when the definition of what constitutes a Never Event in the NHS also changed to require not only actual patient harm but also the potential for significant actual harm. Annual counts have therefore increased, and comparing recent with older data is misleading. The definition continues to undergo more minor change. A provisional report for the 10 month period April 1st 2017 to 31st Jan 2018 acknowledged 393 never events within NHS England, including 172 wrong site surgeries, 97 retained foreign body post procedures, 60 wrong implants/prostheses and 31 medication administration errors.

Recommended actions following a never event

The Leapfrog Group suggested four actions to be taken following a never event:

1. Apologize to the patient
2. Report the event
3. Perform a root cause analysis
4. Waive costs directly related to the event
