Bradford coroner Roger Whittaker was quite right when he branded the series of events that led to the tragic death of Teresa Innes as "a catalogue of errors".

There is simply no other way to describe the blunders by hospital staff which led to Teresa being treated with penicillin when she had a severe allergy to the drug.

The mother of one was left in a persistent vegetative state and eventually had her life support treatment withdrawn. She had only gone into Bradford Royal Infirmary for routine treatment for an abscess on her leg.

It is terrifying that although Teresa wore an allergy bracelet and her condition was flagged up in her notes, she was still given penicillin.

Teresa's family say they can never forgive the medical staff who administered the drug, and it is difficult to find reasons why they should. Errors such as this should simply not happen when people give themselves over to the care of health professionals.

It is of little comfort to Teresa's family, but in the wake of her death important lessons have been learned at Bradford's hospitals and a huge shake-up has - quite rightly - taken place as a result.

Even one death through errors by medical staff is too many, but it is to be hoped that the tragedy of Teresa Innes is never to be repeated, and that Teresa's family can now finally begin to move on from the events of the past five years.
