About 4.3 million people were waiting for hip and cataract surgeries at the end of September if hospitals were to treat patients within 18 weeks
NHS England data show that delays in routine operations are at their poorest levels since January 2009.
At the end of September, about 4.3 million people were waiting for hip and cataract surgery.
Hospitals are supposed to treat patients who do not need urgent treatment within 18 weeks – but 13.3 percent, about 570,000, wait longer.
This is the worst performance in a decade, when the value was 14.5 percent.
Emergency rooms reached a record high of 542,435 last month – an increase of 5.7 percent a year.
Tom Sandford of the Royal College of Nursing said, "Everywhere you look, you see our health system bounce."
Rob Harwood of the British Medical Association said: "The NHS is no longer just a winter crisis – it's now a year-round crisis.
"These numbers should alert the NHS and the government as we approach winter."
NHS England said, "The NHS is increasingly looking after people who need our care."
