Abstract：
UNASSIGNED: Performing accurate estimated fetal weights (EFWs) is a critical skill developed in obstetrics residency training. Resident physicians are often the first to perform EFWs on obstetric patients when they enter care. Evaluating residents\' accuracy in performing EFWs is crucial for assessing their achievement in residency training milestones and providing patient care.
UNASSIGNED: As part of an educational initiative program between 2014 and 2020, postgraduate year 1 (PGY1) and postgraduate year 2 (PGY2) residents performed EFW measurements on 10 term (>37w0d) patients using ultrasound and Leopold\'s maneuver and 10 preterm (>24w0d and <37w0d) patients using ultrasound. Clinical characteristics, mode of delivery, and actual birthweights (BWs) were recorded for each patient. The accuracy of these estimates was evaluated using mixed-effect regression models.
UNASSIGNED: Thirty-three residents, 1127 deliveries, and 1790 EFW measurements were evaluated. Overall, the percentage of residents with estimations within 10% of actual BW went up in PGY2 for Leopold\'s and ultrasound term births, but not for preterm ultrasound births. Maternal body mass index and actual BW were associated with absolute percentage estimation error. After adjusting for these variables, there was a statistically significant decrease in error between PGY1 and PGY2 for Leopold\'s method in term births; ultrasound (term and preterm) showed more modest reductions in error during PGY2.
UNASSIGNED: Resident physicians have accurate estimates of EFWs early in their training, beginning in their first year of residency by both Leopold\'s maneuver and ultrasound. Furthermore, PGY2 residents performed better than PGY1 residents for Leopold\'s method.

摘要：
■执行准确的估计胎儿体重（EFWs）是产科住院医师培训中开发的一项关键技能。住院医师通常是第一个对产科患者进行EFWs的患者。评估住院医师执行EFW的准确性对于评估其在住院医师培训里程碑中的成就和提供患者护理至关重要。
■作为2014年至2020年教育计划的一部分，研究生一年级（PGY1）和研究生二年级（PGY2）居民使用超声对10名（>37w0d）患者进行了EFW测量Leopold的动作和10名早产（>24w0d和<37w0d）患者使用超声。临床特征,交货方式,并记录每位患者的实际出生体重(BWs).使用混合效应回归模型评估了这些估计的准确性。
■33名居民，1127交付，和1790EFW测量进行了评估。总的来说,在PGY2中，利奥波德和超声足月出生的估计体重在实际体重10%以内的居民百分比上升，但不适用于早产超声。产妇体重指数和实际体重与绝对百分比估计误差相关。调整这些变量后，利奥波德方法在足月分娩中PGY1和PGY2之间的误差有统计学意义的显著降低;超声(足月和早产)显示PGY2期间的误差有更适度的降低.
■住院医师在培训初期就对EFWs有准确的估计，从他们居住的第一年开始，利奥波德的演习和超声波。此外，对于利奥波德的方法，PGY2居民的表现优于PGY1居民。
