Civil liberty worries about databases of children's details have been overstated, new findings suggest.

Telford and Wrekin Council, which is running one of the 10 identification, referral and tracking pilots in England, sent out more than 21,000 letters in February informing the local community of plans to store children's basic details on an electronic database.

The council received only 50 queries as a result of the letters, and only five of these were serious concerns about families' civil liberties.

"Families want us to keep shared information," IRT project manager Sara Tough said. "They don't want to keep repeating the same things."

She said it was important to base information-sharing on shared values and that developing a core assessment for all professionals to use was central to this. A common assessment also provided an evidence base for professionals if they needed to share information without parents' consent, she said.

NSPCC policy adviser Natalie Cronin said the charity would support a database that allowed professionals to contact one another, but not one that included concerns about a child, which would then be open to interpretation. She called for details stored on databases to be kept simple, and for a list of what should be stored and shared to be included in the bill.

"Different professions operate to different practices of confidentiality. That is another argument for keeping it simple. That way you are able to get all agencies involved."
