The efficiency of the selection of patients with injured arms and legs for radiography was investigated. The analysis was based on data on presenting signs and symptoms collected in a multicentre study organised by the Royal College of Radiologists working party on the effective use of diagnostic radiology. The work was carried out in eight accident and emergency units in England and Wales. With the help of various computer simulation techniques a combination of signs and symptoms that might usefully improve present practice was sought. The results suggest that for injuries of arms and legs the clinical determinants of bony injury cannot be refined further to improve current selection for radiography. This study shows that existing clinical practice is probably as good as it can be.
对选择手臂和腿部受伤患者进行X光检查的效率进行了调查。该分析基于在皇家放射科医师学院工作组组织的关于有效使用诊断放射学的多中心研究中收集的有关呈现的体征和症状的数据。这项工作在英格兰和威尔士的八个事故和急诊科室开展。借助各种计算机模拟技术,寻找可能有效改进当前做法的体征和症状组合。结果表明,对于手臂和腿部损伤,骨损伤的临床决定因素无法进一步细化以改善当前的X光检查选择。这项研究表明,现有的临床实践可能已经尽可能好了。
