The only staff who should be accessing her medical records are staff who are directly providing care to her and where it is necessary for that care for them to do so.
Anytime someone accesses a patient record that is digitally recorded.
In this instance a member or members of staff who were not involved in her care accessed her records out of nosiness (to find out her cause of death, her injuries etc).
It is an immediate sackable offense which is drummed into you throughout your training and employment. There have been a few high profile cases of it recently and there has been a push (within my Trust anyway) on reminding staff of the seriousness and the consequences.
Theres no suggestion it contributed to her death.
Theres no excuse for it, ever, and you can’t turn around in a NHS building, as a member of staff, without seeing the warnings due to the recent spate high profile cases. So no member of staff can claim they didn’t know.
