Canadian CT Head Rule

Investigator: Ian Stiell

Summary: The Canadian CT Head Rule head rule will permit physicians to standardize care of patients with head injuries and to be much more selective in the use of computed tomography without jeopardizing patient care.

Recently validated at nine Canadian sites and now the subject of a large CIHR-funded implementation study. The physician's dataform used in the validation study is available for review.

Available in several formats here.
