Margaret Hall left to die in Bupa-run Eastbank Care Home in Glasgow A great-grandmother was left to die in the TV lounge of a Glasgow care home despite crying out in pain. Margaret Hall, 78, died at the Eastbank Care Home in Shettleston on July 5, where she was receiving care for dementia. Private health company Bupa, which runs the home, issued an apology to Mrs Hall's family on Monday. Mrs Hall's daughter Elizabeth told the Daily Record: "We're just distraught over what mum went through. She went through hell. And this all happened when we were there to see it. The apology was issued one week after a police investigation was launched into the deaths of four residents at another Bupa-owned home in Edinburgh. Mrs Hall died without the benefit of pain management after staff at Eastbank failed to realise the seriousness of her situation. On a previous occasion, she had been left in a cold bath after a care worker forgot about her. She had moved into Eastbank in November 2009 for dementia care but her family told the newspaper they had filed a number of complaints about the quality of care she was receiving. They were told four days prior to her death that Mrs Hall had had her medication withdrawn and she could no longer swallow pills. Although she was "roaring with pain" on the day she died, doctors did not have alternative pain relief available to help her. Elizabeth Hall said when she questioned why this was she was told the drugs were ordered as needed and not kept on site for "cost and wastage" reasons. Mrs Hall's husband Eric, 75, added: "She had been screaming in pain. The end of life care should have been put in place as soon as they took her off her medication. It was appalling for us to watch and there was nothing we could do. The Hall family filed five complaints with Bupa and the company admitted in a letter that its staff "failed in their duty to ensure your mum had adequate pain management in place." The private-sector health firm conceded its staff failed to recognise that Mrs Hall was nearing the end of her life and act appropriately. They agreed that medication should have been ordered from the patient's GP. The letter also addressed Mrs Hall's being left in the home's TV lounge, saying the staff had not taken the state of her health into consideration. Staff also failed to provide the appropriate oral hygiene care, the letter added. Finally, the company admitted that Mrs Hall had been left in a cold bath six months prior to her death. Vivienne Birch, director of partnerships at Bupa Care Services, also issued a statement apologising for the quality of care given to Mrs Hall. She told the newspaper: "The care we provided to Mrs Hall did not meet the usual high standards we provide, and again we would like to send our apologies and condolences to her family. A thorough investigation revealed that there were concerns raised with regards to Mrs Hall's general care including her pain relief, end of life care and oral care. "As a result, the care home has taken action to ensure that all our residents" needs are met at all times. For example, our staff have since received further training and supervision in end of life care. The health and wellbeing of our residents remains our absolute priority. Mrs Hall's family said they would be taking further action against the home. It comes as a four deaths at another Bupa-owned care home in Edinburgh, Pentland Hill, sparked a joint investigation by Police Scotland and the Health and Safety Executive.
