Abstract：
UNASSIGNED: The objective of the study was to compare the use of ordinal scales and interval scales for capturing surgical competency information for general surgeons performing 3 complex trauma procedures.
UNASSIGNED: Surgical performance assessment is typically captured using nonparametric data (eg, checklists) that do not support inferential analyses. Interval scales support parametric analyses that are essential for determining competency. We compared assessment outcomes for surgeons performing 3 complex trauma procedures using ordinal and interval scales.
UNASSIGNED: All participants were board-certified or eligible general surgeons. Each participant was assessed by an experienced trauma surgeon while performing 3 trauma procedures on cadavers. All assessors completed a rigorous assessment certification process. We calculated descriptive statistics to examine the differences between interval (parametric) and ordinal (nonparametric) outcomes.
UNASSIGNED: Ordinal scales overestimated competence in up to 100% of the participants and did not identify specific performance gaps. Interval scales provided more granularity and identified specific capability gaps.
UNASSIGNED: Imprecise instrumentation conveys a false sense of competence and deprives surgeons of opportunities to close capability gaps. Measuring discrete procedural components with interval scales provides a more precise measurement of surgical competency.

摘要：
■该研究的目的是比较使用序数量表和间隔量表来捕获进行3种复杂创伤手术的普通外科医生的手术能力信息。
■手术性能评估通常使用非参数数据（例如，清单)不支持推理分析。区间量表支持对确定能力至关重要的参数分析。我们比较了使用序数和间隔量表进行3种复杂创伤手术的外科医生的评估结果。
■所有参与者均为董事会认证或符合条件的普通外科医生。每位参与者由经验丰富的创伤外科医师进行评估，同时对尸体进行3次创伤手术。所有评估人员都完成了严格的评估认证过程。我们计算描述性统计数据来检查区间（参数）和序数（非参数）结果之间的差异。
■序数量表高估了多达100％的参与者的能力，并且没有确定具体的绩效差距。间隔尺度提供了更多的粒度和确定的具体能力差距。
■不精确的仪器传达了一种错误的能力感，并剥夺了外科医生缩小能力差距的机会。使用间隔量表测量离散的程序组件可以更精确地测量手术能力。
