Faulty air system closes Malton and Whitby operating theatres
Operating theatres at two North Yorkshire hospitals have been closed because of a "significant" ventilation problem, it has been revealed.
Patients who had surgery planned at Malton and Whitby Hospitals are having their operations rearranged.
An annual check found ventilation systems at the theatres in both hospitals were "performing below the required standards".
Health officials have now decided both theatres will be closed from Monday.
In a statement, Mike Proctor, the chief executive of Scarborough and North East Yorkshire Healthcare NHS Trust, said it had been agreed that use of the theatres would be suspended.
"This is a precautionary measure based on the need to preserve high standards of patient safety," he said.
"We are reviewing those patients who are due to have their procedures in the coming days, and will weigh the balance of risk as to whether rescheduling their procedure is a greater risk to them than allowing it to take place.
"To bring these theatres up to standard will require significant investment," added Mr Proctor.
