NHS trust where 755 "excessive" deaths happened in last three years expected to be probed The figures were compiled by Professor Sir Brian Jarman, of the independent Dr Foster Intelligence Unit, which monitors hospital performance, and who will be consulted by Sir Bruce on which trusts should be examined. He said: "Sir Bruce has talked about investigating 12 trusts altogether, but it's difficult to know where to draw the line. Last year, for example, 22 hospitals had higher than expected mortality rates. I would suggest a good place to start is to look at hospitals that have had had high mortality rates in recent years and which have also had high mortality rates historically, such as Hull, Dudley and Barking. Last year the family of an 86-year-old Alzheimer's sufferer complained to Hull Royal Infirmary after she was sent home in a taxi wearing two hospital gowns, instead of being dressed and sent home in an ambulance. Rose Gibson was described as being "freezing" and "frightened" by her daughter, Margaret. The hospital was described as a "hell hole" by Denise Harrison, whose mother Dorothy died there in 2009, where she was treated with "no dignity." The trust's chief executive, Phil Morley, said: "The Trust has seen its mortality rates decrease significantly over the past two years. The number of deaths in our hospital are now rated "as expected" for every indicator used by the Department of Health. At present we have not been told whether we will face an inspection. Sir Brian's figures are calculated using a measure called Hospital Standardised Mortality Ratios, which he says is more accurate than the Department of Health's Summary Hospital-level Mortality Indicator. The latter gives much higher numbers of deaths because it includes those which occur up to 30 days after leaving hospital. Earlier this week Sir Bruce announced he would be investigating five trusts where more than 3,000 people may have died needlessly over the past two years: East Lancs, Colchester, Tameside, Blackpool and Basildon and Thurrock. He will announce next week which other hospitals will also be put under investigation.
