The purpose of this study was to compare the accuracy of first-trimester pelvic sonography done by physicians after a 2-week emergency ultrasound elective to similarly numbered examinations done by physicians longitudinally over several years of residency training.
We conducted a secondary analysis of a previously reported prospective study of pelvic sonography for symptomatic first-trimester pregnancy. The 21st through 40th examinations were compared between those who completed an emergency ultrasound elective and those who did not. The reference standard was pelvic sonography done by the department of radiology.
Eighty-six examinations (34%) were done by 12 operators who did not participate in an emergency ultrasound elective, and 171 examinations (67%) were done by 13 operators who completed an emergency ultrasound elective. There was no statistical difference between the groups with regard to identifying an intrauterine pregnancy, molar pregnancy, ectopic pregnancy, or adnexal mass.
The accuracy of pelvic sonography for first-trimester pregnancy was comparable between physicians who participated in a 2-week emergency ultrasound elective and those who performed the same number of examinations over a longer period during residency training.
本研究旨在比较在参加为期2周的急诊超声选修课程后，医师进行的孕早期盆腔超声检查的准确性，与在多年住院医师培训期间纵向进行相同次数检查的医师所做检查的准确性。
我们对先前报道的一项针对有症状的孕早期妊娠盆腔超声检查的前瞻性研究进行了二次分析。比较了完成急诊超声选修课程的人员和未完成该课程的人员之间第21次至第40次检查的情况。参考标准是由放射科进行的盆腔超声检查。
12名未参加急诊超声选修课程的操作人员进行了86次检查（34%），13名完成急诊超声选修课程的操作人员进行了171次检查（67%）。两组在识别宫内妊娠、葡萄胎妊娠、异位妊娠或附件包块方面无统计学差异。
参加为期2周急诊超声选修课程的医师与在住院医师培训期间较长时间内进行相同次数检查的医师相比，孕早期妊娠盆腔超声检查的准确性相当。
