The purpose of this study was to identify, through recursive partitioning, clinically relevant criteria which predict the need for acute neurosurgical intervention in a group of patients with mild head injury. ⋯ A simple three step rule predicts the need for acute neurosurgical intervention based on clinical findings: a deteriorating GCS; an initial GCS of 13; and the presence of associated injuries or comorbid conditions.
