Faculty evaluations of residents' diagnostic performance in radiology subspecialty rotations were examined in two studies in order to ascertain whether the relative capabilities of residents change during training and to predict residents' diagnostic performance using a three-dimensional form perception test. In the first study, numeric ratings by faculty members were averaged to provide interpretive/diagnostic scores for each of 16 residents in each of 5 consecutive half-years. Sixty-seven percent of the relative differences among residents' diagnostic proficiencies persisted during training. The magnitude of these unchanging differences between individuals in diagnostic performance strongly favors resident selection based upon diagnostic potential. An additional 22% of the relative differences correlated with an abrupt change in the rank order of residents in diagnostic performance at the beginning of the second year of residency. This rearrangement of ranks may have resulted from an abrupt change in the tasks and expectations assigned to residents. In the second study, correlations between scores on a recently described Form Test and monthly faculty ratings of diagnostic performance were computed. An average diagnostic performance score for each resident was generated for all rotations combined, each of eleven subspecialties, and all rotations completed within a given half-year. Scores on the Form Test correlated well with these combined diagnostic scores, further substantiating results reported previously. Form Test scores were highly correlated with subspecialty diagnostic performance scores in subspecialties using cross-sectional imaging methods, such as neuroradiology. Although Form Test scores were poorly correlated with half-year diagnostic performance during the first year, they were highly correlated with performance beginning in the second year.
在两项研究中,对放射学亚专业轮转中住院医师的诊断表现进行了教员评估,以确定住院医师的相对能力在培训期间是否发生变化,并使用三维形状感知测试预测住院医师的诊断表现。在第一项研究中,将教员的数字评分进行平均,为连续5个半年中每组16名住院医师提供解释性/诊断性分数。住院医师诊断能力的相对差异中有67%在培训期间持续存在。个体诊断表现中这些不变差异的大小强烈支持基于诊断潜力进行住院医师选拔。另外22%的相对差异与住院医师第二年开始时诊断表现排名顺序的突然变化相关。排名的这种重新排列可能是由于分配给住院医师的任务和期望突然改变所致。在第二项研究中,计算了最近描述的形状测试得分与教员每月诊断表现评分之间的相关性。为所有轮转组合、11个亚专业中的每个亚专业以及在给定半年内完成的所有轮转生成了每个住院医师的平均诊断表现分数。形状测试得分与这些综合诊断分数相关性良好,进一步证实了先前报告的结果。在使用横断面成像方法的亚专业中,如神经放射学,形状测试得分与亚专业诊断表现得分高度相关。尽管形状测试得分在第一年与半年诊断表现的相关性较差,但从第二年开始它们与表现高度相关。
