A recent report found that surveyed residents overestimated patients’ surgical risk compared with the risk determined by the American College of Surgeons Surgical Risk Calculator (ACS-Calculator).¹ However, owing to the survey’s 7 clinical scenarios describing patients in extremis with severe comorbidities, the ACS-Calculator’s estimations, which served as a reference for expected morbidity, seemed to be low. Because the ACS-Calculator was recently updated to address accuracy and calibration,² this study sought to determine whether new ACS-Calculator estimates more closely match the residents’ estimations of risk and to determine actual outcomes of similar patients in the National Surgical Quality Improvement Project (NSQIP).

最近的一份报告发现，与美国外科医生外科手术风险计算器（ACS-Calculator）确定的风险相比，接受调查的居民高估了患者的手术风险。¹然而，由于该调查的7种临床情况描述了患有严重合并症的极端患者，ACS-Calculator的估计值（可作为预期发病率的参考）似乎很低。由于ACS计算器最近进行了更新以解决准确性和校准问题，因此本研究²试图确定新的ACS计算器估计值是否与居民对风险的估计值更加匹配，并确定国家手术质量改善项目中类似患者的实际结果（NSQIP）。
