Comparison of Hands-on Versus Online Learning About Ocular Ultrasound

Comparison of Hands-on Versus Online Learning in Teaching Ultrasound Skills for Eye

In patients who visit an emergency room with ocular symptoms, point-of-care ultrasound can quickly identify several emergency diseases. While training of eye ultrasound skills is useful for emergency physicians, hands-on education is risky in pandemic situation such as coronavirus disease 19 (COVID19). As a solution to this, non-face-to-face education via online has been on the rise. The investigators hypothesized that even an online education is enough to perform basic eye ultrasound by emergency physician.

Study Overview

• Status: Unknown
• Conditions: Emergencies
• Intervention / Treatment: Other: online group

Detailed Description

Since the eye is an superficial organ, it has excellent access to ultrasound. Also, the eye has a liquid-filled structure (vitreous body), it is suitable for obtaining some important findings with bedside ultrasound. In patients who visit an emergency room with ocular symptoms, point-of-care ultrasound can quickly identify several emergency diseases. While training of eye ultrasound skills is useful for emergency physicians, hands-on education is risky in pandemic situation such as COVID19. As a solution to this, non-face-to-face education via online has been on the rise. The investigators hypothesized that even an online education is enough to perform basic eye ultrasound by emergency physician.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: hands-on group; The doctors who participated in the study will be educated ocular ultrasound scanning method by hands-on about 20 minutes, and perform ocular ultrasound scans on two standard patients.
Other: online group; The doctors who participated in the study will be educated ocular ultrasound scanning method by online lecture about 20 minutes, and perform ocular ultrasound scans on two standard patients.	Other: online group; In terms of teaching ultrasound, video lectures will be conducted rather than hands-on, which is the traditional method.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
scan score	We make our own guideline to evaluate ocular ultrasound scans. The ocular ultrasound images performed participants are evaluated according to the guideline. We compare the scores of the hands-on group and the online group to see if there is a significant difference between the two groups.	through study completion, an average of 1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Optic nerve sheath diameter (ONSD)	Two ultrasound experts measure the standard patient's ONSD and use it as a reference value. The course of ocular ultrasound scanning involves measuring ONSD. We compare the measured ONSD of the hands-on group and the online group to see if there is a significant difference between the two groups.	through study completion, an average of 1 year
