All children who visit accident and emergency (A&E) departments or have out-of-hours GP consultations will be logged in a national database, health minister Dr Dan Poulter has said.
The system is designed to help doctors and nurses spot children who are suffering from abuse or neglect and avoid cases like that of Baby P, he said.
Doctors and nurses will be able to see if the children they treat are subject to a child protection plan or are being looked after, and whether they have been a frequent visitor to A&E.
