理论基础和目标。作者进行了这项研究，以确定多发创伤患者的搜索满意度(SOS)错误是否由错误的视觉扫描、错误的识别或错误的决策造成。对多发伤患者进行了一系列的X线片检查。放射科医生在两个实验条件下对每个系列进行解释：当系列中的第一张X光片包括骨折时，以及当它不包括时。在第一个实验中，最初的X光片显示四肢无移位的骨折(轻微骨折)；在第二个实验中，初始X光片显示临床上更重要的异常(主要骨折)，每个系列还包括一张带有细微(测试)骨折的X光片和一张测量检测准确性的正常X光片。在每个实验中，凝视停留时间被记录下来，因为10名放射科医生检查了10个模拟多发伤病例的图像。只有在第二个实验中才能证明SOS效应。对停留时间的分析表明，当初始X线片包含骨折时，对后续X光片的搜索缩短：然而，错误不是基于错误的扫描。肌肉骨骼损伤的SOS效应不是由扫描错误引起的。对有较大但不是较小的附加骨折的测试骨折的SOS效应的证明表明，检测到其他骨折与检测到的骨折的严重程度成反比。
Rationale and Objectives. The authors performed this study to determine whether satisfaction of search (SOS) errors in patients with multiple traumas are caused by faulty visual scanning, faulty recognition, or faulty decision making.Materials and Methods. A series of radiographs were obtained in patients with multiple traumas. Radiologists interpreted each series under two experimental conditions: when the first radiograph in the series included a fracture, and when it did not. In the first experiment, the initial radiographs showed nondisplaced fractures of the extremities (minor fractures); in the second experiment, the initial radiographs showed abnormalities of greater clinical importance (major fractures), Each series also included a radiograph with a subtle (test) fracture and a normal radiograph on which detection accuracy was measured. In each experiment, gaze dwell time was recorded as 10 radiologists reviewed images from 10 simulated cases of multiple trauma,Results. An SOS effect could be demonstrated only in the second experiment. Analysis of dwell times showed that search on subsequent radiographs was shortened when the initial radiograph contained a fracture: however, the errors were not based on faulty scanning.Conclusion. The SOS effect in musculoskeletal trauma is not caused by faulty scanning. Demonstration of an SOS effect on test fractures with major but not minor additional fractures suggests that detection of other fractures is inversely related to the severity of the detected fracture.
