Almost 1,500 patients were waiting for routine treatment at the Solent Trust in December, figures show.

A health think tank said while the overall waiting list appears to be stabilising, “the Prime Minister’s pledge to bring the waiting list down will not be met”.

NHS England figures show 1,479 patients were waiting for non-urgent elective operations or treatment at Solent NHS Trust at the end of December – up from 1,393 in November, and 1,198 in December 2022.

Of those, one had been waiting for longer than a year.

The median waiting time from referral at an NHS Trust to treatment at the Solent Trust was 10 weeks at the end of December – up from nine weeks in November.

Nationally, 7.6 million people were waiting to start treatment at the end of December – slightly down from 7.61 million in November and the third consecutive fall.

Sarah Scobie, acting director of research at the Nuffield Trust, said: “While 6,000 is only a very small fall, it has been achieved despite industrial action and winter pressures.”

However, she added the figures show the Prime Minister’s pledge to bring the waiting list down will not be met.

“In fact, today’s figures reveal that there are almost 400,000 more outstanding treatments now than when Sunak’s pledge was made last January.

“While the overall waiting list for treatments or operations appears to be stabilising, it is hard to see a route to making faster and more significant progress, with staff already working flat out and under immense pressure.”

Separate figures show 1.6 million patients in England were waiting for a key diagnostic test in December – the same as in November.

At the Solent Trust, 920 patients were waiting for one of two standard tests, such as Cardiology - Echocardiography, or Magnetic Resonance Imaging at this time.

Of them, 533 (58%) had been waiting for at least six weeks.

Professor Pat Price, co-founder of the #CatchUpWithCancer campaign, said the King has demonstrated transparency, leadership, and courage in his reaction to his recent diagnosis and has given cancer an increased profile, which is “a timely reminder that the disease will touch every family across the land as one in two of us will be diagnosed”.

He added: “In light of the continuing dire state of cancer performance in our country confirmed again by these figures, we are urging the Government to show similar qualities and adopt a new ‘get it done’ approach.

“If ever there was a time for a serious new priority on cancer, backed by radical action, it must be now.”

A Department of Health and Social Care spokesperson said: “Cutting waiting lists is one of the Government’s top five priorities and, despite winter pressures and the impact of industrial action, overall NHS waiting lists have decreased for the third month in a row.

“We’re determined to continue improving patient care, having already delivered on our promise to create 5,000 extra permanent hospital beds and 10,000 hospital at home beds, freeing up capacity and cutting waiting times.”
