Escalating nurse strike action by withdrawing protection for emergency hospital care will endanger patient safety, a NHS leader has warned as the government said a “full and final” pay offer had been made to staff.

Matthew Taylor, chief executive of the NHS Confederation, which represents health trusts, also raised concerns over the possibility of nursing staff and junior doctors walking out at the same time in the dispute over pay.

His comments came as the Royal College of Nursing (RCN) announced on Friday its members will strike for 48 hours from 8pm on 30 April after rejecting the government’s pay offer.

NHS nurses in emergency departments, intensive care and cancer wards will also take industrial action for the first time.

Mr Taylor told Trevor Phillips on Sky’s Sophie Ridge On Sunday programme that removing derogations agreed by the unions – agreed protections for certain areas of care – would have an impact.

He said: “We are concerned about the speculation that the possibility of a combination of junior doctors’ and nurses’ action, so both of these things would be a significant escalation.

“It’s very difficult to see how either of those things wouldn’t endanger patient safety and dignity.”

He added: “When we’re talking about derogations, irrespective of the past, being excluded in this industrial action, so it does affect, for example, emergency services.

“And when we’re talking about the possibility of combined industrial action, this type does take us into unchartered territory.”

Mr Taylor added: “The people that I represent will have to spend a great deal of time doing the detailed planning, the detailed negotiation with trade unions locally to try to ensure that we protect life and limb.

“We do want to avoid this industrial action.”

He went on: “The NHS has been run down, underfunded particularly in relation to capital investment in terms of workforce.

“So we’re not always able to provide the care that we want, but we are able to make progress.

“I think what’s heartbreaking for people I represent is that they’re doing that work. They’re making inroads, they’re seeing progress, we’re starting to get closer to our targets and then these days of industrial action really knock us back.”

“It is a difficult job day in day out but it becomes almost impossible when you’re dealing with industrial action as well.”

Meanwhile, Conservative Party chairman Greg Hands told Sky news a “full and final” pay offer had been made to nurses.

He pointed out NHS members of Unison, the largest NHS union had accepted the deal of a 5% pay rise this year and a cash payment for last year.

The RCN leadership had also recommended the package, which its members then rejected.

Mr Hands said: “We think that we’ve made a fair and reasonable offer.

“It is a full and final offer. But we are waiting for the other results to come in from the other unions.”

He added: “Steve Barclay is always willing to talk so long as there aren’t preconditions attached, and so long as there isn’t the threat of strikes going on at the moment.”

Labour’s shadow secretary Wes Streeting urged the RCN to continue to protect emergency lifesaving care during further strikes.

He said: “I’d appeal to them, if they are going on strike again, to continue to protect patient care… I am really worried about patient safety actually in the middle of all of this.”

He told the Ridge show: “There just aren’t circumstances in which I’m going to sit on your programme and say I think it’s right to remove cover for emergency care, for cancer care. I think that’d be the wrong thing to do.”
