Dr Isyaka Mamman pleaded guilty to manslaughter over the death of Shahida Parveen in 2018 at Royal Oldham Hospital. The 85-year-old, who had previously been suspended for lying about his age, used the wrong needle and inserted it in the wrong place, puncturing the sac that held Ms Parveen’s heart. The court heard how the 48-year-old lost consciousness as soon as the needle was inserted, prompting her husband to leave the room shouting: “He killed her. I told him to stop three times and he didn’t listen.” Before her death, Mamman was responsible for a number of critical incidents, including one that left a patient permanently disabled. Sentencing him at Manchester Crown Court, Mrs Yip said the death was his primary responsibility but the hospital trust should have done more after Mamman lied about his age and skipped earlier procedures. The Nigerian-born doctor’s “true age” remains a matter of “dispute”, a court has ruled, as his birthplace did not have a birth registration system. He obtained a medical degree in Nigeria in 1965 and worked in the UK from 1991 but, throughout his career, gave several different dates of birth. During his medical training, he dated September 16, 1936, which meant he was 21 when he began his medical training and 81 at the time of the fatal incident. He later revised his date of birth back to 1941 and, nearing retirement, changed it again to October 1947. The date, meaning he started his degree at the age of 10, was used in his application for naturalization as a British citizen in 2001. Three years later, he was found guilty of serious professional misconduct by the General Medical Council and suspended for 12 months for lying about his age.
