Inspectors have ordered Southern Health Foundation Trust to make urgent improvements to the services it provides at two mental health units in Oxford.

The Care Quality Commission issued an enforcement notice to the trust this month after an inspection of its Headington site found it to be in breach of six essential standards.

The trust was found to be in breach of essential standards relating to the care and welfare of service users, cleanliness, the safety of premises, the availability and suitability of equipment, inadequate monitoring of quality and the safe keeping of personal records.

The regulator’s report determined the building housing both units was unsafe for patients and service users.

The CQC also discovered that medicines were not always administered or stored safely, with some emergency equipment not working adequately.

Some staff records at both the John Sharich House and the short term assessment and treatment team units at the Slade House site were also found to be inaccurate.

The trust has been asked to send an action plan to the regulator by 17 December describing how it will improve standards.

A trust statement said: “We were most concerned to learn of the issues brought to light by the CQC. We worked with the CQC on the day to put right all the environmental problems that were raised and we have been working hard to rectify the remaining issues. We are concerned the points raised in the report did not come to light sooner and have launched our own internal investigation.”

Southern Health said that it was closing the site to new admissions while changes were made.

The CQC inspected the facilities in September.
