A Nottinghamshire mental health hospital has been criticised by a watchdog after nurses administered medicines incorrectly.

Priory Hospital East Midlands, in Annesley, remains under special measures after a fresh inspection by the Care Quality Commission (CQC).

The site is a 28-bed specialist acute and psychiatric intensive care service for female patients.

The commission held an unannounced inspection in August after receiving concerns about safety at the hospital shortly after another visit in June.

During the June inspection, staff were told they must ensure that medicines were managed properly.

But the August the CQC report stated: "We were notified of three recent medicines errors, which involved nurses administering intramuscular injections to a patient.

"This medicine had not been prescribed by a doctor. We also received information of concern relating to the restraint of people using the service."

Following the August visit the CQC did not issue a new rating for the hospital, so it remains 'inadequate' as rated in June.

Inspectors visited both female wards at the hospital during the inspection.

A spokesperson said the hospital had put a detailed action plan in place following the inspection.

Inspectors found staff had improved the recording of physical health care observations after a patient was tranquillised.

Managers had also taken "appropriate actions" with staff when they had been made aware of medicines errors.

A hospital spokesman said: "A detailed action plan is in place, implemented by a new hospital manager working with a multi-disciplinary team, who are ensuring all necessary improvements are made.

"Care plans are audited regularly and we have made robust improvements to our medicines management processes, including around the planned introduction of electronic prescribing, and ensuring that all lessons are learned across the hospital.

"Verbal discussions with the CQC confirm that positive change has already taken place. Our governance systems have been reviewed and we are working closely with external agencies to ensure improvements are demonstrable and sustained."
