Ultrasound is a non-radiated diagnostic tool that can be performed at the bedside in emergency departments and critical care settings. Traditionally, junior residents learn from patients by performing sonography on them. However, patient rights, patient safety, and medical quality are raising concerns.

How to enable junior doctors to be effectively familiar with ultrasound operations and to effectively integrate them into daily practice has become a major challenge in medical education. Also, the ultrasound-guided clinical procedure is included in the ultrasound core applications in the American College of Emergency Physicians statements.

This aim of this study is to establish an ultrasound-guided simulation curriculum and to evaluate the efficacy. The subjects of the study are junior doctors who are interested in clinical procedures in the emergency department or other relevant medical departments, and it is estimated that 200 people will be enrolled.

Inclusion Criteria:

• participants attended the curriculum.

Exclusion Criteria:

• not attended the curriculum
