A woman with an infected cat bite died from sepsis after she was sent home from hospital without the proper treatment.
Newham General Hospital has apologised over the death of 61-year-old Gabriele Kreichgauer.
A junior doctor who saw her searched for “cat bite” on an internet database but was directed to cat scratch fever, which has different treatment.
She was discharged without antibiotics and died two days later.
Barts Health NHS Trust, which runs the east London hospital, said: “We are sorry for the failings in the care we gave to Ms Kreichgauer.”
Philip Barlow, assistant coroner for Inner South London, said in a prevention of future deaths report that when Ms Kreichgauer visited A&E on 21 January 2018, the junior doctor used a paid-for internet database called Uptodate.
