Earlier this year, the Prime Minister asked Professor Sir Bruce Keogh - the Medical Director of NHS England - to review the quality of care and treatment provided by 14 NHS hospitals that have shown higher than expected mortality ratios over the past two years.
Basildon is one of those hospitals.
The review aims to discover whether there are any sustained failings in the quality of care and treatment being provided. It will also examine the Trusts plans to improve the care it delivers to patients.
The review followed the publication of the Francis Report into Mid-Staffordshire Hospitals.
That report concluded that "patients were routinely neglected by a Trust that was preoccupied with cost cutting, targets and processes and which lost sight of its fundamental responsibility to provide safe care."
The visit to Basildon Hospital is expected to last 2 days. Professor Keogh will report on his findings by the summer.
