The use of computed tomography (CT) in emergency departments has increased over several decades, as physicians increasingly depend on imaging for diagnoses. Patients and medical personnel are put at risk due to frequent exposure to and higher levels of radiation, with very little evidence of improvements in outcomes. Here, we explore why CT imaging has a tendency to be overused in emergency departments and the obstacles that medical personnel face in ensuring patient safety. The solution requires cooperation from all emergency care stakeholders as well as the continuous education of doctors on how CT scans help in particular cases.
几十年来，由于医生越来越依赖影像学诊断，急诊部门中计算机断层扫描（CT）的使用量不断增加。由于频繁接触和更高水平的辐射，患者和医务人员面临风险，而在改善结果方面几乎没有证据。在这里，我们探讨为什么 CT 成像在急诊部门中倾向于过度使用，以及医务人员在确保患者安全方面面临的障碍。解决方案需要所有急诊护理利益相关者的合作，以及对医生进行有关 CT 扫描在特定情况下如何提供帮助的持续教育。
