More treatments had been outstanding for a year or more at Oxford University Hospitals Trust as of August, figures show.

The NHS set a target of eliminating waits of more than a year by March 2025, but the latest NHS England figures suggest Oxford University Hospitals Trust may struggle to meet it.

The figures show there were 87,600 outstanding treatments at Oxford University Hospitals NHS Foundation Trust – 3,911 (four per cent) of which had been waiting for a year or more.

This was a 34 per cent rise from 2,925 a year earlier.

The largest number of year-long waits at the trust were for trauma and orthopaedic services, with 984 outstanding treatments.

This was followed by urology services, with 508 treatments.

Danielle Jefferies, a senior analyst at the King’s Fund, said the strong national focus on tackling longest waits has “paid off”, particularly thanks to the extra work doctors have put in working weekends and opening community diagnostic centres.

However, she said these waits are only a “small part of the story” in solving the health service’s problems – with the overall waiting list already significant before the pandemic.

Ms Jefferies added: “It's not just about these waiting lists, but who is waiting”. She would like to see the problem tackled inclusively, adding these long waits are disproportionately for women's health services.

Nuffield Trust researcher Cyril Lobont said progress has been mixed – while longer waits have been on the decline, the NHS may miss its target of eliminating the longest waits by early next year.

“The NHS objective was to eliminate 65-week waits by September, but they have only gone from 49,000 in March to 46,000 in August,” he added.

“Meanwhile, in August, waits of over a year were at the lowest level since the start of the pandemic. But the goal to eliminate these waits by March 2025 will be incredibly difficult to meet given the rate at which they have decreased so far this year.”

A Department of Health and Social Care spokesperson said: "This government inherited a broken NHS, with waiting lists sat at record highs and too many patients facing a postcode lottery, waiting far too long to be diagnosed and treated.

“Our 10-Year Health Plan will fundamentally reform the health system through three big shifts – from hospital to the community, analogue to digital and sickness to prevention.”

They continued: “We will cut waiting lists, delivering 40,000 more appointments a week, and we will create a healthier society while ensuring patients receive the highest quality care when and where they need it.”
