The Care Quality Commission (CQC) said that two thirds of acute hospitals were either inadequate or required improvement.
University Hospitals of Morecambe Bay Trust (UHMBT), which runs the Royal Lancaster Infirmary, is one of 13 hospital trusts currently in special measures after it received an inadequate rating in June 2014.
The CQC said that “England’s health and social care system is under pressure”.
The report concluded: “Changing care needs and tough financial demands have contributed to an environment where higher quality is hard won.
“But our inspections show that improvement is possible, and we must look to the best to understand what works and why.
“For the first time, our State of Care report draws on findings from our new, more thorough inspections across all of the sectors we regulate.
“From this, we’re starting to build a comprehensive picture of quality across England and identify the elements that drive high-quality care.
“Care providers are being asked to make savings and meet the more complex needs of an ageing population, while ensuring that the health and care system can survive and remain financially stable in the future.
“The NHS has had to cope with increasing pressure but budgets have seen smaller increases than before.
“Adult social care providers have been asked to do more for less, as local authority funding has been reduced.
“Despite these pressures, many providers have managed to improve or maintain quality.”
