The Nightingale Hospital remains in a “state of readiness” in anticipation of a second wave of the coronavirus pandemic, an NHS chief has said.

The temporary hospital was built at the ExCeL in early March with capacity for 4,000 intensive care beds.

NHS leaders feared London’s hospitals would be overwhelmed with critically ill patients, and members of the military were brought in to help build it in nine days.

However, the Nightingale stopped admitting new patients in early May after receiving just 41 people.

Now, a senior manager at Barts Health Trust, the NHS body that runs the Nightingale, has said it could still be needed.

Andrew Hines, the Trust’s group director of corporate development, said: “We very much maintain the Nightingale at the moment in a state of readiness for future requirements, and that’s an active process requiring significant work to ensure it can meet the task, if we are asked to reopen that capacity.

“But thankfully at the moment it remains in a state of readiness.”

His statement, during a Trust board meeting on June 5, underlines speculation that a second wave could come later this year, and that it could harm as many patients as were infected during the first wave.

Mr Hines also explained why the Nightingale saw so few patients before it closed.

He said: “It’s a real positive that the Nightingale hasn’t been required at the level of capacity that we initially envisaged might be necessary, and that’s really for two reasons.

“The success of the NHS in London and beyond in freeing up critical care capacity and expanding capacity to cope with the peak demand.

“And I think, because Londoners as a whole have really risen to the challenge of social distancing and have minimised transmission, in a way that the peak has clearly been lower than it might have been.”
