The use of radiography of the arms and legs (extremity radiography) in 32936 patients attending eight accident and emergency units was studied. Although extremity radiography was satisfactory in terms of cost per bony injury detected (40 pounds), considerable differences between centres in the predicted and actual yields of bony injury were observed. Guidelines for selection of patients for extremity radiography would reduce variability in its use and improve the quality of present practice.
对8个事故与急救科室的32936名患者进行了四肢X线摄影(肢体X线摄影)的使用情况研究。尽管就每例检出的骨损伤成本而言(40英镑),肢体X线摄影令人满意,但各中心在骨损伤的预测产量和实际产量方面存在显著差异。制定肢体X线摄影患者选择指南将减少其使用的变异性,并提高当前的医疗质量。
