More must be done to improve the "safety and responsiveness" of hospitals put into failure regimes, England's chief inspector of hospitals has said.
While hospitals put into special measures have shown "significant improvements" more must be done to address these issues, Professor Sir Mike Richards added.
Putting hospital trusts in special measures was a move introduced as part of the Government's response to the Stafford Hospital scandal.
A year ago, following a review into 14 hospital trusts with higher than expected death rates, 11 trusts were put into special measures for a catalogue of failings and fundamental breaches of care.
Tameside Hospital was one of those Trusts put into special measures, and required to stay in special measures, despite showing improvements.
Professor Sir Mike Richards said: "Although there have been improvements, it is important to emphasise that further improvements need to be made, especially in relation to safety and responsiveness.
"Our new inspection model has helped us get under the skin of hospitals. The special measures process is doing what it set out to do, and I am confident that it will lead to further improvements."
