Determining which children with a minor head injury require a CT scan

Thousands of children arrive each day to Emergency Departments across Canada with head injuries. Most are mild but a few may be life-threatening. Dr. Martin Osmond and colleagues across Canada developed the CATCH 2 rule. With this rule physicians are better informed of those at high risk for bleeding inside the head and this can assist them in determining who requires a prompt CT scan or close observation. It can also lessen anxiety for families of children whose injuries are determined to be less severe.
