To assess whether adult trauma center status influences radiology resident performance on trauma cases in the Emergent/Critical Care Imaging SIMulation (WIDI SIM) exam.
This retrospective study analyzed 29,290 WIDI SIM exam scores from 110 adult trauma cases across 55 radiology residency programs. Residents were categorized by training level-R1 (n = 17,801), R2 (n = 9,136), R3 (n = 1,826), R4 (n = 527)-and by their program's adult trauma center designation: Level 1 (n = 20,121), Level 2 (n = 1,870), Level 3 (n = 1,029), Level 4 (n = 487), and no trauma designation (n = 5,834). A Generalized Linear Mixed Model with a negative binomial distribution was used to evaluate the effect of trauma center status on resident performance, adjusting for resident level, imaging modality, and case specialty.
After adjusting for confounding variables, there was no statistically significant difference in resident scores based on adult trauma center status (p > 0.05 for all trauma levels compared to no trauma designation). Resident level significantly influenced performance, with higher-level residents scoring better than R1 residents (p < 0.001 for R2-R4). Imaging modality and case specialty also significantly affected scores. Residents performed better on MR, US, and XR modalities compared to CT (p ≤ 0.002), and scored lower on chest, cardiovascular, musculoskeletal, and neuro cases compared to abdominopelvic cases (p < 0.001).
Adult trauma center status did not significantly impact radiology resident performance on trauma cases in the WIDI SIM exam. Resident training level, imaging modality, and case specialty were significant factors influencing performance. These findings suggest that resident education and exposure to diverse imaging modalities and specialties are more critical determinants of diagnostic accuracy than the trauma center designation of their training program.
评估成人创伤中心的级别是否会影响放射科住院医师在急诊/重症监护影像模拟（WIDI SIM）考试中对创伤病例的表现。
这项回顾性研究分析了来自55个放射科住院医师培训项目的110例成人创伤病例的29290份WIDI SIM考试成绩。住院医师按培训水平分为R1（n = 17801）、R2（n = 9136）、R3（n = 1826）、R4（n = 527），并按其所在项目的成人创伤中心指定级别分类：1级（n = 20121）、2级（n = 1870）、3级（n = 1029）、4级（n = 487），以及无创伤指定级别（n = 5834）。使用具有负二项分布的广义线性混合模型来评估创伤中心级别对住院医师表现的影响，并对住院医师级别、成像方式和病例专科进行了调整。
在对混杂变量进行调整后，基于成人创伤中心级别的住院医师成绩没有统计学上的显著差异（与无创伤指定级别相比，所有创伤级别p均>0.05）。住院医师级别对表现有显著影响，级别较高的住院医师得分高于R1住院医师（R2 - R4与R1相比p < 0.001）。成像方式和病例专科也对成绩有显著影响。与CT相比，住院医师在MR、US和XR成像方式上表现更好（p≤0.002），与腹部盆腔病例相比，在胸部、心血管、肌肉骨骼和神经病例上得分较低（p < 0.001）。
成人创伤中心级别对放射科住院医师在WIDI SIM考试中对创伤病例的表现没有显著影响。住院医师培训水平、成像方式和病例专科是影响表现 的重要因素。这些发现表明，住院医师教育以及接触多种成像方式和专科，比其培训项目的创伤中心指定级别，是诊断准确性更关键的决定因素。
