From reading the letter from the 3 paediatric consultants, it does shed some light on the "terrible errors" that the doctor is said to have personally made.
The one about stopping the resusicitation- it appears that patients had been moved on the wards during the shift- bear in mind, this doctor was covering a minimum of 4 wards or something and she would not have been aware of every single transfer/change of bed by each patient. That sounds more like the responsibility of senior ward staff.
It seems she attended an arrest situation for one patient several hours previously in her shift- that patient had a DNAR (do not resuscitate) form completed for them.
It then sounds like the patient Jack was transferred into this bed/bay.
Being called back to the same bed/ward, it was not unreasonable for the doctor to assume that it was the patient who she had treated earlier.
It is inexcusable that the resuscitation was stopped on the wrong patient, but surely there would have been a ward manager/senior nursing staff present who would know (presumably) where each patient on their ward was located and any recent movements?
And in an emergency situation, surely there would have been other staff members responding?
I do not think that this doctor can be given the blame entirely for this.
