Quantification of training in obstetrical ultrasound: a study of family practice residents

This study was done to determine how rapidly physicians in training could become competent in performing obstetrical ultrasound for the purposes of routine evaluations (i.e., the standard examination as defined by AIUM). The scan measurements and results of organ surveys of 12 family medicine residents were compared with the results obtained by faculty members experienced in obstetrical ultrasound. Residents rapidly became proficient in biometry. The mean menstrual age calculated from BPD, AC, HC, and FL differed from faculty values by 0.381 weeks after residents had performed 40 supervised scans. Organ survey success rates demonstrated similar high concordance between resident and faculty scans.
