To determine whether a medical student emergency ultrasound clerkship has an effect on the number of patients undergoing ultrasonography and the number of total scans in the emergency department.
We conducted a prospective, single-blinded study of scanning by emergency medicine residents and attendings with and without medical students. Rotating ultrasound medical students were assigned to work equally on all days of the week. We collected the number of patients scanned and the number of scans, as well as participation of resident and faculty.
In seven months 2,186 scans were done on the 109 days with students and 707 scans on the 72 days without them. Data on 22 days was not recorded. A median of 13 patients per day were scanned with medical students (CI 12-15) versus seven (CI 6-9) when not. In addition, the median number of scans was 18 per day with medical students (CI 16-20) versus eight (CI 6-10) without them.
There were significantly more patients scanned and scans done when ultrasound medical students were present.
确定医学生急诊超声实习是否会影响急诊科进行超声检查的患者数量和总扫描次数。
我们进行了一项前瞻性、单盲研究，研究对象为有和没有医学生的急诊医学住院医生和主治医生进行的扫描。轮转的超声医学专业学生被平均分配到一周的所有日子工作。我们收集了扫描的患者数量和扫描次数，以及住院医生和教师的参与情况。
在七个月的 109 天有学生的日子里进行了 2186 次扫描，在 72 天没有学生的日子里进行了 707 次扫描。有 22 天的数据未记录。有医学生时，每天扫描的中位数为 13 名患者（CI 12-15），而没有医学生时为 7 名（CI 6-9）。此外，有医学生时每天的中位数扫描次数为 18 次（CI 16-20），而没有医学生时为 8 次（CI 6-10）。
当有超声医学专业学生在场时，接受扫描的患者和扫描次数明显更多。
