			*Derivation study only from Canadian centers; subsequent validation studies have shown lower specificity in other settings
			*Does not address the question of which patients need CT vs clinical observation
			*GCS of 15 required for application, limiting use in moderate-severity head injuries
			*Specific criteria (e.g., "dangerous mechanism") are subjectively defined and may be interpreted differently by clinicians
			*Study excluded patients on anticoagulants, limiting applicability to this growing population
