A diabetic patient who was given a lethal dose of insulin by a community nurse was unlawfully killed, a coroner has ruled.
Newly-qualified community nurse Joanne Evans now faces multiple inquiries after the decision today at an inquest in Cardiff.
Her employer, Gwent Healthcare NHS Trust, said Ms Evans is not working at the moment because of an internal disciplinary procedure.
However the trust could not give further information as her case has been referred to the Nursing and Midwifery Council.
The Crown Prosecution Service (CPS) has also said that it would review the case after the verdict.
A CPS spokesperson said: ‘The Crown Prosecution Service (CPS) considered this case very carefully indeed and concluded that a tragic mistake had occurred.
‘However, on reviewing the available facts, the CPS decided that there was insufficient evidence to offer a realistic prospect of conviction for gross negligence manslaughter.
‘The CPS has explained the decision to the victim’s family and now a verdict of unlawful killing has been returned, the CPS will review its decision as a matter of course. Our thoughts remain with the victim’s family at this time.’
The inquest heard that Ms Evans injected Margaret Thomas, 85, with 10 times the correct dose of insulin.
She miscalculated the dose because she used a conventional syringe instead of an insulin pen, the court heard.
Ms Thomas, who was registered blind and could not self-administer insulin, collapsed and died six hours after the injection, the court heard.
Basic nurse training instructs them to always use special insulin syringes because insulin is measured in units, not millilitres.
Ms Evans apologised about her mistake at the inquest. However her son, Dr Hywel Thomas, said: ‘It is apparent that there were failings in her training and clinical judgment to request further assistance. The verdict today confirms this.’
