 A seriously ill grandfather had his lungs accidentally washed out with cleaning detergent at an NHS hospital, a report has revealed. According to an internal investigation report by Salford Royal Hospital, a second, "thorough washout of the right lung" was carried out when the error was realised. While he was being treated for a head injury and multiple fractures, Hannah developed a lung infection, and his doctor decided to do a saline flush, a common treatment to clear out the sick lung.

 When a doctor tried to improve his breathing he was mistakenly handed a bottle containing detergent mixture to wash out Mr Hannah's lungs. “The review of Mr. Hannah’s care at Salford Royal highlighted that he did not receive the high standard of care we always pride ourselves on delivering and we apologize unreservedly to his family for this,” Dr. Pete Turkington, the Trust’s medical director, tells PEOPLE in a statement. “We have since introduced new measures to ensure something like this will not happen again.” 
 
 “We once again offer our deepest sympathies to William Hannah’s family for the loss of their much loved family member.”

 Turkington said the Trust has worked with the Hannah family throughout the investigation and has held several meetings — but Hannah’s daughter Lisa said not enough has been done. "Our dad didn't deserve to have this happen to him and that's why we are trying to ensure that no other families suffer as we have."
– A UK hospital made an "appalling" error right before a 68-year-old died there, says his daughter, and now she and her family are suing the hospital for it. William Hannah passed away in September 2017 at Salford Royal Hospital while being treated after a car accident that had left him with several broken bones and serious head injuries, the BBC reports. Hannah also developed a lung infection, and it was while trying to ease his breathing that hospital staff made the mistake that has spurred the Hannah family's complaint. Per a release from their lawyers, a doctor went to flush out one of Hannah's lungs with saline solution, but an assistant accidentally passed him a bottle of cleaning detergent instead, which the doctor then "unknowingly" used to rinse Hannah's lung, People reports. The doctor realized the mistake afterward and tried to get as much of the detergent out of Hannah's lung as he could, but Hannah's lawyers say the grandfather's condition deteriorated and he died the next day. In a statement to People, the hospital's medical director acknowledges that Hannah "did not receive the high standard of care we always pride ourselves on." The BBC cites an internal hospital report that found what happened to Hannah was due to various factors, including poor communication and staff training, a container without a label, an equipment cart that wasn't adequately stocked, and "distraction by other life critical tasks." An inquiry into the exact cause of Hannah's death will take place in early 2019. (Glenn Frey's widow says Mount Sinai caused his death.)
