Patients taken to Bristol hospitals by ambulance have been waiting more than an hour to be seen by A&E.
Last week, almost 160 patients at one trust alone waited 60 minutes or longer to be transferred from the ambulance team to accident and emergency (A&E) staff.
This was recorded by University Hospitals Bristol and Weston NHS Foundation Trust (UHBW), with 158 such delays in the seven days to Sunday (January 17) - the second-highest figure of all acute trusts in England.
The only trust to record more was University Hospitals Birmingham NHS Foundation Trust, PA news agency reports, with 237 delays of more than 60 minutes.
UHBW runs A&Es at Bristol Royal Hospital for Children, Bristol Royal Infirmary and Weston General Hospital, while Southmead Hospital's A&E is run by North Bristol NHS Trust.
North Bristol's figure was low in comparison, with just 11 ambulance-A&E handovers taking more than an hour last week.
The weekly figures were released by NHS England, as it continues to measure the impact of the coronavirus pandemic.
Despite previous images showing queues of ambulances outside hospitals, a handover delay does not always mean a patient has waited in the ambulance.
They might have been moved into an A&E department, but staff were not available to complete the handover.
Nationally, more than 3,300 patients waited longer than an hour to be handed over last week.
This was down from 5,513 the previous week, which was the highest weekly figure so far this winter.
That week, UHBW recorded 169 handovers in excess of an hour.
The trust declined to comment on the NHS England figures, but has not downplayed the pressures facing its staff as hospital admissions continue to climb.
