Ethical issues

PrincipleHow it applies here
AutonomyParents cannot decide anything for their child without the truth. Hospitals owe families that truth when something may have gone wrong, which is called the duty of candour, and these parents waited until the police made an arrest.
Non maleficenceEvery doctor has a duty to raise concerns when patients are at risk, and to keep raising them if nothing happens. The consultants at Chester did, and the inquiry found that the hospital's leaders did not believe them.
JusticeDoctors and nurses answer to regulators who can end their careers, and until now NHS managers have not. The government's barring scheme is meant to close that gap.
