Turn Stafford anger into action, says Obama adviser

The man leading a review of patient safety in the NHS has said he wants to turn the anger over the Stafford hospital scandal into action.

Don Berwick, a former health adviser to President Obama, has been commissioned by the government to introduce a "zero-harm culture" into English hospitals.

Speaking exclusively to the BBC for the first time since his appointment, Prof Berwick said he fully understood the anger of those who had lost relatives at Stafford hospital between 2005 and 2008, having read their accounts.
