A 30-STONE woman who had a gastric bypass operation died at a hospital where staff hadn't been properly trained to care for obese patients.

Janice Barnardo, 46, was the first patient to undergo the weight-loss surgery at Tameside Hospital and was taken back in to repair problems with the surgery five days later.

A Stockport inquest heard staff were not trained to operate adapted beds for patients recovering from the surgery.

Miss Barnardo's bed - specially designed to provide support for overweight patients - had been left unplugged for two days. It was called a bariatric bed after the branch of medicine that deals with obesity.

Sections of the beds can be raised and lowered automatically to keep patients comfortable and prevent bed sores. Pathologist Andrew Yates said the cause of death was heart failure, gross obesity, high blood pressure, diabetes, asthma and pressure sores.

Jane Doyle, surgical ward manager, said staff had not been trained to operate bariatric beds. She said: "The hospital's bariatric policy was in draft form and had not been finalised."

Elaine Hughes said when her sister, Miss Barnardo, was put on a ward after leaving intensive care she felt unhappy.

Mrs Hughes said: "When she came back from the intensive care unit at Tameside, Janice was put in a bed at an angle at the end of a long ward.

"The first thing you saw coming on to the ward was Janice in a huge bed. She felt like she was in a freak show.

"We asked that she be moved to a side ward. That was so cramped we could not get around the bed." Miss Barnardo, from Mossley, had the operation in February 2007 and required surgery to repair a leak five days later. By the end of the following month, surgeon Abduljalil Benhamida discharged her to Shire Hill, Glossop, for rehabilitation.

But Miss Barnardo later developed deep bed sores and in May 2007 she returned to Tameside with septicaemia and later died.

Coroner John Pollard recorded a verdict of misadventure. He criticised nursing notes and said he would write to the chief executives of the local NHS trusts highlighting his concerns. After the inquest, Mrs Hughes said: "Janice's problems started on ward 15 at Tameside Hospital. Staff were not trained to care for bariatric patients."

A spokeswoman for Tameside Hospital Trust said: "This case highlights the complex medical and psychological rehabilitation needs of patients undergoing surgery of this nature and the need for careful assessment, planning and co-ordination of services to minimise the risk of similar problems in the future."

Jill Pinington, of Tameside and Glossop primary care trust, said: "Since Miss Barnardo's death an audit has shown a significant improvement in standards of documentation and note-keeping."
