Claire Marx, president of the Royal College of Surgeons, criticised the NHS’s failure to give patients planned care in hospital within the required 18 weeks, such as surgery for cataract removals, hernia repairs and hip and knee replacements.

The number of people in England who are awaiting such treatments has climbed to almost 3.9 million.

Hospitals are meant to treat 92% of patients on the “referral-to-treatment” (RTT) waiting list within 18 weeks, according to guarantees in the NHS constitution. However, they did so in just 91.3% of cases in July, NHS-wide performance data released on Thursday shows. It was the service’s worst RTT performance in more than five years.

Hospitals met the 92% target in nine categories of RTT patients, including those requiring treatment for eye problems (92.7%), cardiac care (92.7%) and gynaecological problems (92.3%). However, it missed the target in 10 other categories. It treated barely four of of five (81.7%) of all those awaiting neurosurgery within 18 weeks, 86.9% of those needing plastic surgery and 88.9% of trauma and orthopaedic patients.

“It feels as if the NHS has stepped through the wardrobe and into the perpetual winter of Narnia,” Marx said. “We cannot forget that behind these statistics are potentially very ill and anxious patients who are being made to wait far too long for treatment. This is the true impact of the serious financial pressure we’ve seen the NHS come under in recent months.”

The NHS also missed targets covering A&E, ambulance response times, diagnostic tests, two forms of cancer treatment and rapid first treatment for those experiencing psychosis for the first time.

Dr Mark Holland, president of the Society for Acute Medicine, said: “This data reflects a system which is close to breaking down.”

Bed blocking has reached record levels. In July a total of 184,188 bed days were lost to delayed discharges – when patients are fit to leave but social care support is not in place – up sharply from 147,376 in the same month last year, and the highest number since records began in August 2010.

At midnight on the last Thursday in July, 6,364 patients who were fit to leave were still in their beds, up from the previous record of 6,105 patients the month before.

“For every 100 people who come to A&E, around 30 are admitted and, of these, 20 come under acute medicine. That number is increasing and our front-of-house workforce is depleted,” Holland said.

“However, performance is most significantly hampered due to our inability to discharge people at the backdoor of our hospitals. Failure to get people home is, in my view, a national emergency.”

Medical leaders want ministers to urgently pledge more money for the NHS to tackle its growing problems.

Marx said: “The forthcoming autumn statement offers an opportunity for the government to provide more money for the NHS and social care, and to agree to a cross-party commission to review how we can make the NHS sustainable for the long term. Without a serious look at what the NHS needs in funding, we will remain in a state of constant winter.”

NHS England said that despite missing so many targets, its performance was still very good by international standards.

“As the NHS responds to ever increasing care needs, hospitals are continuing to look after more than nine out of 10 A&E patients within four hours, and more than nine in 10 patients are waiting less than 18 weeks for their routine operations,” said Matthew Swindells, its national director of operations and information.
