One in 10 operations in England cancelled with less than 24 hours’ notice

About one in 10 operations in England are cancelled with less than 24 hours’ notice or postponed, according to research.

A study of elective surgery at 91 English NHS trusts found that 10% of operations were cancelled the day before the planned surgery date; while 9% were postponed when patients had their pre-op appointment.

If the study’s findings were replicated nationally, that would equate to approximately 300,000 cancellations or postponements. Yet nearly 40% of cancellations could be avoided, the authors concluded.

Researchers for the National Institute for Health and Care Research Central London patient safety research collaboration, NHS England, University College London and the Royal College of Anaesthetists examined planned surgery data over seven days in November 2024. They found that the most common causes of cancellations were for medical reasons, patients not attending, operating lists overrunning and emergency admissions. But in 37.3% of cases, had these issues been identified as little as three to five days earlier, the operation could either have gone ahead, or another patient could have been offered the surgery slot, the study calculated.

The study, published in the British Journal of Anaesthesia, also found that nearly two-thirds of operations postponed at the pre-op appointment were because patients needed further tests or specialist clinical review.

The authors concluded that clinical pathways need overhauling, with more early screening, nimbler surgery scheduling and better communication.
