助産師が受けた超音波教育に関する研究

Abstract

We investigated ultrasound education received by 337 midwives who actually perform ultrasound examination in institutions with a midwifery clinic or midwifery centers with beds, and obtained the following results. 1) Of the 337 midwives, 63.5% received ultrasound education before performing ultrasound examination. The site that provided the education was the hospital where they work in 70.1%, and the instructor was a physician in 76.6%. 2) The median total pre-service education time was 18.5 hours, and only 8.5% of them considered the education time to be adequate. 3) Slightly less than 30% of the midwives considered that their ultrasound findings were accurate. The median number of ultrasound examinations they performed until they gained confidence in the accuracy of their findings was 30 in the group with and 50 in the group without pre-service education. The former group showed a higher percentage of midwives considering that their ultrasound findings were accurate, and also gained confidence in accuracy after fewer examinations than the latter group. 4) The educational contents more than 50% of the midwives received were observing the method to operate ultrasound equipment and training in this method, and the contents more than 50% considered to be important were basic knowledge of ultrasound (lectures on the purpose/advantages of ultrasound, and those on the gestational periods for ultrasound examination/diagnostic points according to the gestational period), the method to operate ultrasound equipment (lectures and training), imaging diagnosis (lectures/study by observation/training), and coping methods when they detect deviations from normal. Thus, OJT in the hospital where each midwife works contributed to the education of midwives performing ultrasound examination, and the group who received pre-service education had more confidence in the accuracy of their ultrasound findings compared with the group not receiving this education. These results suggest the necessity of systematic education in ultrasound before and during actually providing the service.
