Elderly doctor left patient 'covered in blood' before he killed mum in botched procedure

Elderly doctor left patient 'covered in blood' before he killed mum in botched procedure

Dr Isyaka Mamman, 85, carried out a negligent bone marrow procedure on Anthony Johnson that left him "covered in blood" before doing the same to Shahida Parveen with deadly consequences


An elderly doctor who killed a mum-of-three in a botched procedure had left another patient "covered in blood" just a few months earlier.

Anthony Johnson, 54, was attended to by Dr Isyaka Mamman at the Royal Oldham hospital after being told he needed a bone marrow biopsy, the Manchester Evening News reports.

Three months after that appointment, Dr Mamman killed 48-year-old Shahida Parveen when he carried out the same procedure in a grossly negligent manner in September 2018.

Anthony said he had complained to the hospital after he ended up covered in blood when he returned home.

He told how he was left 'horrified' after learning that the doctor had gone on to kill a patient.

"I couldn't believe it," he said. "Oldham have not said one thing to me about this."

The Northern Care Alliance Trust said it would not have been able to disclose details regarding ongoing investigations into clinicians to patients.

Anthony, a former taxi driver from Radcliffe, Bury, recalled meeting the doctor in June 2018.

He said he had not been told to stop taking blood thinners two days prior to the procedure, as is typically advised. Before the biopsy, he said Dr Mamman asked him whether he had stopped taking them.

He left the room and returned 15 minutes later to say it was safe to proceed, Anthony said. He said the doctor then made 'attempt after attempt after attempt' to gain a sample via his hip bone.

"He just could not get it," Mr Johnson said.

"Even though I was under anaesthetic I could really feel him digging."

After arriving home, the bus driver who'd driven him noticed his T-shirt was 'drenched' and covered in blood. An ambulance was called and later paramedics arrived to stem the bleeding.

Anthony said he complained to the hospital about Dr Mamman following the appointment in June 2018. It emerged this week that the doctor had also been involved in two serious incidents in 2015 while carrying out biopsies.

A 64-year-old man went into cardiac arrest and suffered permanent disability, and a woman was left in considerable pain.

"The worst outcome of this was the death of a patient could have been avoided," Anthony said.

Before jailing him for three years for gross negligence manslaughter, the judge said Dr Mamman, who was 81 when he killed Mrs Parveen, should have retired following the incidents in 2015.

Mrs Justice Yip added: "The Trust ought to have taken steps to safeguard patients and should not have allowed you to continue carrying out potentially dangerous procedures without supervision after 2015."

Pennine Acute Hospitals NHS Trust, now known as the Northern Care Alliance, has apologised to Mrs Parveen's family and agreed a settlement after a claim for damages for clinical negligence was brought. The trust have also apologised to Anthony.

David Jago, Chief Officer at Oldham Care Organisation, said: "We would like to apologise to Mr Johnson for the standard of care provided to him, which did not meet our usual high standards.

"We met Mr Johnson to discuss his care and to answer his questions in November 2021, which we hope he found beneficial and supportive.

"We’ve used his feedback to make improvements to some of our processes."

Mr Johnson, who has been diagnosed with emphysema, says he first heard about the death of Mrs Parveen after the doctor was charged in November last year. The Trust said it has learned lessons from her death.

Dr Chris Brookes, Group Chief Doctor and Deputy Chief Executive for the Northern Care Alliance NHS Foundation Trust, said: "Following Mrs Parveen’s death in September 2018, the trust launched a thorough internal investigation to examine the circumstances leading up to and following this tragic incident.

"The trust implemented improvements following an investigation which were shared with Mrs Parveen's family.

"The trust has admitted liability in relation to a civil claim brought by the family. The trust has liaised closely with Greater Manchester Police throughout their investigation and the subsequent legal proceedings concerning Dr Mamman."

The Trust said 'no restrictions' were in place on Dr Mamman's work at the time of Mrs Parveen's death, in September 2018, after concerns about him were 'investigated in line with the usual processes in place'.

Policies have now changed across the trust. Bone marrow biopsies are only to be conducted via the pelvis, unless a sternum biopsy is required with any such procedure being carried out under the supervision of a consultant haematologist.
