To the Editor: Dr Smits and colleagues1 generated independently derived data on the performance of both the New Orleans Criteria (NOC) and the Canadian CT Head Rule (CCHR) for the use of computed tomography (CT) in patients with minor head injury. Although it is reassuring that both rules have high sensitivity for neurosurgical intervention, the sensitivity of the CCHR for clinically important findings appears to be too low (83.4%-87.2%) to support selective use of CT for minor head trauma.
