Comparison of Hands-on Versus Online Learning About Ocular Ultrasound

Study Overview
=================
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. 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<br>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<br>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<br>* In terms of teaching ultrasound, video lectures will be conducted rather than hands-on, which is the traditional method.<br>|

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 |
