Comparison of Hands-on Versus Online Learning About Ocular Ultrasound

Not Applicable

• Conditions: Emergencies
• Interventions: Other: online group

• Registration Number: NCT04834700
• Lead Sponsor: Samsung Medical Center

Brief Summary

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.

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.

Arm && Interventions

Group	Intervention	Description
online group	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.

Primary Outcome Measures

Name	Time	Method
scan score	through study completion, an average of 1 year	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.

Secondary Outcome Measures

Name	Time	Method
Optic nerve sheath diameter (ONSD)	through study completion, an average of 1 year	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.
