The busiest and quietest times of the week for accident and emergency services at Gloucestershire Health and Care NHS Trust over the last year have been revealed.
It comes as A&Es across England are at breaking point, with attendance reaching pre-pandemic levels in November and a record proportion of patients facing waits of more than four hours.
Chancellor Jeremy Hunt has announced an additional £3.3 billion in NHS funding to deal with increased demand and soaring inflation, but health think tank the Nuffield Trust said it is too late "to have a meaningful impact this year".
NHS Digital figures show that the worst hour of the week to visit A&E at Gloucestershire Health and Care NHS Foundation Trust was between 12pm and 1pm on Mondays in the year to March.
Patients waited an average of one hour and 29 minutes to be either admitted to an inpatient ward, transferred elsewhere or discharged from hospital.
Meanwhile, the shortest waits were between 7pm and 8pm on Tuesdays, when patients waited an average of 37 minutes.
Of the seven days of the week, Monday was the worst day overall to visit A&E at Gloucestershire Health and Care NHS Trust, with patients waiting an average of one hour and 17 minutes, while Saturday was the best, when the average wait time dropped to one hour and two minutes.
Monday saw the highest average number of patients attending across the year, while Sunday saw the lowest.
The figures come as the NHS deals with increasing pressures during the recovery from the coronavirus pandemic.
Separate NHS England figures show more than 30% of patients waited more than four hours to be seen at A&Es across England in November – a new record for the third month in succession.
The Nuffield Trust said a significant factor is the growing number of patients taking up hospital beds as they wait to be discharged because support from health and care social services outside of hospital is not ready.
Jessica Morris, fellow at the Nuffield Trust, said: "While the Government has now confirmed when the NHS will see some additional funding to tackle these delays, it is too late in the day to have a meaningful impact this year.
"Patients with no choice but to stay in hospital beds when they are medically fit enough to be cared for elsewhere is a serious problem for both the patients and NHS staff across the system."
Health and Social Care Secretary Steve Barclay said he is supporting staff by "investing record amounts into health and social care, including committing an additional £8 billion for health and social care in 2024-25".Mr Barclay added that some 7,000 extra beds will also be created and £500 million will see 24-7 support centres will be rolled out across England, "speeding up discharge from hospital and helping to ease pressures and get patients treated and out of hospital faster."
