Lynn’s Queen Elizabeth Hospital closed its maternity unit 24 times in the past year.
The QEH was among five hospitals with the highest number of closures. The information was released after a BBC Freedom of Information request.
The trust says the decision is based on bed occupancy and staffing requirements. Surrounding hospital trusts are notified.
Valerie Newton, deputy director of nursing and patient experience said: “It should be noted that when the unit is closed, the closure is reviewed on a four hourly basis with a view to see if it is able to be re-opened. The trust closely monitors any closures of the delivery suite and it is reported on a monthly basis to the local clinical commissioning group.”
The unit was last closed on July 1 between 7.05am and 10.30am, with no women being diverted to a different unit. There were also two closures in June with no diversions.
The last pregnant woman to be sent to a different hospital was in May.
