The initial 227 consecutive prenatal ultrasound examinations by two family physicians in an urban community health center were compared with actual birth outcomes. Of 186 examinations for which follow-up information was available, 162 infants were represented. The sampling rate was 81%. No serious anomalies were noted by ultrasound. One placenta previa, one fetal death, and two unsuspected cases of twins were detected by ultrasound. These data represent one of the first detailed reports of outcomes reflecting family physicians' psychomotor and cognitive skill in the use of obstetric ultrasound. The high accuracy (92% to 96%) of correct ultrasound dating suggests that a short postgraduate continuing medical education course was effective for these two family physicians. The accuracy rate compares favorably to more rigorous training. This structured format utilizing the average of four direct measurements for ultrasound-estimated gestational age and three anatomy ratios for assessing proper imaging relationships or growth symmetry may be useful as other family physicians develop educational methods and quality-assurance protocols in this area.
在一个城市社区卫生中心，两位家庭医生对最初连续进行的227次产前超声检查与实际分娩结果进行了比较。在有随访信息的186次检查中，涉及162名婴儿。抽样率为81%。超声检查未发现严重异常。超声检查发现1例前置胎盘、1例胎儿死亡和2例未被怀疑的双胎病例。这些数据是反映家庭医生使用产科超声的心理运动和认知技能的首批详细结果报告之一。超声孕周测定的高准确率（92%至96%）表明，一门简短的毕业后继续医学教育课程对这两位家庭医生是有效的。该准确率与更严格的培训相比具有优势。这种利用超声估计孕周的四个直接测量值的平均值以及用于评估适当成像关系或生长对称性的三个解剖学比率的结构化格式，可能会在其他家庭医生制定该领域的教育方法和质量保证方案时发挥作用。
