The criticism raises fresh questions about how warning signs were handled at the U.K. hospital.
• Letby was found guilty of killing seven babies and attempting to murder six others while working at the Countess of Chester Hospital.
• The judge’s remarks focused on the hospital’s systems for identifying unusual deaths and responding to concerns about Letby’s conduct.
• Families have questioned why Letby remained in a clinical role after doctors reportedly noticed a rise in unexpected collapses and deaths in the neonatal unit.
• The case has prompted scrutiny of hospital leadership, internal investigations and the procedures used to escalate concerns about staff.
• Letby continues to deny the charges and is serving multiple life sentences. A public inquiry is examining how the deaths occurred and whether earlier intervention could have prevented further harm.
The findings are expected to shed light on the decisions made by hospital officials and the safeguards intended to protect vulnerable newborns.
