Hundreds of patients were waiting for routine treatment at Cornwall Partnership Trust in May, figures show.

Junior doctors walked out on Thursday as part of five days of industrial action – amid record waiting lists across England.

NHS England figures show 321 patients were waiting for non-urgent elective operations or treatment at Cornwall Partnership NHS Foundation Trust at the end of May – up from 309 in April, but a decrease on 592 in May 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 Cornwall Partnership Trust was four weeks at the end of May – the same as in April.

Nationally, 7.5 million people were waiting to start treatment at the end of May.

Junior doctors walked out for five days from 7am on Thursday in the longest spell of industrial action in the history of the health service.

They return to work at 7am on July 18 and 48 hours later consultants are set to strike for two days. Radiographers across 43 NHS trusts will also walk out for two days from July 25.

Sir Julian Hartley, chief executive of NHS Providers, also called industrial action a “black cloud” hanging over the health service, which is currently in the “most challenging period of operational pressure”.

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

At Cornwall Partnership Trust, 119 patients were waiting for urodynamics tests.

Of them, 85 (71%) had been waiting for at least six weeks.

Dr Sarah Scobie, acting director of research at the Nuffield Trust think tank, said: "Figures this morning on NHS performance and GP patient experience illustrate clearly that there will be no sudden return to the waiting times the public have been promised and still expect".

"Yesterday's update from the NHS that it will adjust recovery targets on waits for planned operations is an acceptance of the difficult reality services now face with no end to doctor strikes in sight," she added.

Health and Social Care Secretary Steve Barclay said: "It is disappointing that the BMA is going ahead with further strike action. This five-day walkout by junior doctors will have an impact on thousands of patients, put patient safety at risk and hamper efforts to cut NHSwaiting lists."

A Department of Health and Social Care spokesperson said: “This Government is working to cut waiting times and the NHS is treating record numbers of patients each day."

“We have virtually eliminated 18-month waits, and are taking immediate action to improve urgent care, getting 800 new ambulances on the road, adding 5,000 hospital beds and scaling up virtual wards," they added.
