Inspectors saw 10 patients being directed between departments without any record being made, meaning the hospital had “no oversight or ownership” of them.
At one point, 18 patients were waiting in an area designed for 10, overcrowding which the CQC said risked meaning staff could not provide safe care and treatment.
Staff did not always have sufficient time and resources for effective governance and risk management, the report said, and data collection was inconsistent.
There was a “slow pace of change” between the CQC’s two inspections in December and January, the report added.
The CQC will continue to monitor the NHS trust to oversee the required “rapid and sustained improvements”.
A Section 29A notice issued earlier this month will remain in place until the CQC is assured that all required improvements have been fully embedded.
A spokesperson for the trust said: “We also know there is more to be done to improve, and we are committed to ensuring teams have the right support in place to deliver the standard of care they want to provide.
“We know we can do better, and we will.”
