Although a checklist has been recommended for preventing satisfaction of search (SOS) errors, a previous research study did not demonstrate that benefit. However, observers in that study had to turn away from the image display to use the checklist. The current study tested a vocalized checklist to avoid this constraint.
A total of 64 chest computed radiographs, half containing various "test" abnormalities, were read twice by 20 radiologists, once with and once without the addition of a simulated pulmonary nodule. Readers used a vocalized checklist-directing search. Receiver operating characteristic (ROC) detection accuracy and decision thresholds were analyzed to study the effects of adding the nodule on detecting the test abnormalities.
Adding nodules induced a substantial reluctance to report the other abnormalities (P < 0.001), as had been the case in the most recent study of the SOS effect in radiography.
The vocalized checklist did not reduce nor eliminate the SOS effect on readiness to report further abnormalities. Although useful for organizing search and reporting, particularly among students, a vocalized checklist does not prevent SOS effects.
尽管推荐使用检查表来预防检索满足误差（SOS），但之前的一项研究并未证明其益处。然而，该研究中的观察者必须从图像显示界面移开视线去使用检查表。本研究测试了一种语音检查表以避免这一限制。
20名放射科医生对总共64张胸部计算机断层扫描影像读片两次，其中一半包含各种“测试”异常，一次添加模拟肺结节，一次不添加。阅片者使用语音检查表指导检索。分析接受者操作特征（ROC）检测准确性和决策阈值，以研究添加结节对检测测试异常的影响。
添加结节导致报告其他异常的意愿大幅降低（P < 0.001），这与最近一项关于放射学中SOS效应的研究情况相同。
语音检查表并未减少或消除SOS效应，即对报告其他异常的准备状态的影响。尽管语音检查表对组织检索和报告很有用，特别是对学生而言，但它并不能预防SOS效应。
