A hospital trust has paid out £27m to families following more than 200 clinical damage claims in the past four years.
Colchester Hospital NHS Trust is one of 14 trusts under investigation for high death rates following the Mid Staffordshire Hospital scandal.
Data from the NHS Litigation Authority revealed how, in the last four years, 219 families have made clinical claims against the trust.
However, the trust said it was confident about its safety record.
Dr Gordon Coutts, chief executive of Colchester Hospital University NHS Foundation Trust, told the BBC: “The public can be absolutely reassured that we are putting patients, their safety and wellbeing at the heart of everything we do.
“I am confident that our hospitals are safer and delivering better care than ever before, but we are also passionate about making further improvements.”
Hospital mortality data suggests over the past two years there were as many as 598 more deaths than statistically would be expected.
Over the past decade, the number of unexpected deaths is more than 1,000.
Inspectors will spend two days at Colchester General and Essex County Hospitals later this summer.
