Tens of thousands of patients were waiting for routine treatment at Royal United Hospitals Bath in January, new figures show.

It comes as a health and social care think tank warned of a "continued backlog for care" in England.

NHS England figures show 39,914 patients were waiting for non-urgent elective operations or treatment at Royal United Hospitals Bath NHS Foundation Trust at the end of January – down slightly from 40,110 in December, but an increase on 34,794 in January 2024.

Of those, 621 (2%) had been waiting for longer than a year.

The median waiting time from referral to treatment at Royal United Hospitals Bath was 14 weeks at the end of January – up from 13 weeks in December.

Nationally, 6.3 million people were waiting to start treatment at the end of January — up slightly from 6.2 million at the end of December.

But an estimated 7.4 million treatments were waiting to be carried out at the end of January, which was down from 7.5 million at the end of last year.

Thea Stein, chief executive of the Nuffield Trust, welcomed the drop but warned improvements must still be made.

She said that, although the figures highlight progress has been made on the number of treatments waiting to be carried out nationally, efforts are "dwarfed by the magnitude of the continued backlog for care".

As NHS leaders meet today to discuss funding, she said "it is crystal clear" the financial pressures faced by the NHS are linked to a higher demand for healthcare, a "poor or patchy" provision of social care, and a lack of funding in primary and community care.

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

At Royal United Hospitals Bath, 11,164 patients were waiting for one of 13 standard tests, such as an MRI scan, non-obstetric ultrasound or gastroscopy at this time.

Of them, 4,187 (38%) had been waiting for at least six weeks.

Other figures show cancer patients at Royal United Hospitals Bath are not being seen quickly enough.

The NHS states 85% of cancer patients with an urgent referral should start treatment within 62 days.

But NHS England data shows just 75% of cancer patients urgently referred to Royal United Hospitals Bath in January began treatment within two months of their referral.

That was up from both 72% in December, and 69% in January 2024.

Professor Pat Price, leading oncologist and chair of Radiotherapy UK, said: "Today's cancer data shows that yet again we are going backwards, and the cancer crisis is only deepening.

"Cancer patients are still waiting too long, and stagnation at frighteningly bad waiting times cannot fall off the agenda."

She warned that, despite pressures on public funding, "the primary obligation must always be to deliver high-quality care".

"Cancer patients cannot afford further delays – cancer cannot be the collateral-timely treatment is the minimum they deserve," she added.

Health and Social Care Secretary Wes Streeting welcomed the drop in the NHS waiting list, but warned "there is still a long way to go" to fully address waiting times.

He added: "By delivering the 2 million more appointments we promised before the election, ending the strikes, and reforming the NHS to drive up productivity, we are putting the NHS on the road to recovery.

"Through the Prime Minister’s Plan for Change, we will cut the longest waiting times from 18 months to 18 weeks, so the NHS is there for you when you need it, once again."
