Concern over Lucy Letby's "association" with numerous baby collapses were raised eight months before she stopped working on a neonatal unit, a court has been told.
Letby, 33, is accused of murdering seven babies and attempting to murder 10 others at the Countess of Chester Hospital between June 2015 and June 2016. Letby denies the allegations.
On Tuesday, consultant Dr Ravi Jayaram told the court they said "significant concerns" while a second consultant said he "wished" the hospital had "gone straight to the police".
