The hospital trust which runs the Princess Royal in Haywards Heath has been visited by health inspectors.
The Care Quality Commission (CQC) visited the Royal Sussex County Hospital in Brighton, which is run by Brighton and Sussex University Hospitals Trust (BSUH) on June 22.
Following their last visit in May last year, inspectors rated the trust as require improvement, although effectiveness and caring are rated as good.
In a letter to staff, Matthew Kershaw, chief executive of BSUH said: “Many of you will already be aware, but for those who are not, I need to let you know that today [June 22] the Care Quality Commission (CQC) arrived to undertake an unannounced inspection, primarily focussed on the Acute Floor at the County.”
He said inspectors would be speaking to staff and patients and assessing the progress the trust has made since their full inspection in May 2014. Mr Kershaw added he will share feedback with staff as soon as the trust has it.
