Given radiation- and sedation-associated risks, there is uncertainty about which children with head trauma should receive cranial computed tomography (CT) scanning. A high-quality and high-performing clinical prediction rule may reduce this uncertainty. ⋯ Eight clinical prediction-rule derivation studies were identified. They varied considerably in population, methodologic quality, and performance. Future efforts should be directed toward validating rules with high quality and performance in other populations and deriving a high-quality, high-performance rule for young children.
