This study is intended to perform a comparative analysis of novice ultrasound users when taught in person versus virtually. This study aims to show that students will not demonstrate a statistical difference in scores learning in in a virtual environment, guided by professionals, when compared to students learning ultrasound in a traditional, in-person format. Utilizing a Butterfly ultrasound machine, a hand held personal ultrasound device, students wil be guided through a FAST (Focused assessment with sonography in trauma) examination and imaging of the carpal tunnel using modules and instructor aid. The FAST (Focused assessment with sonography in trauma) exam images the heart and abdomen for free flowing blood. The carpal tunnel is a region in the wrist that houses the tendons for finger movement. Participants will be assessed on the ability to identify key regions, anatomical landmarks and confidence in utilize the ultrasound machine.
This project intends to adapt previous research ("Innovations with tele-ultrasound in education sonography: the use of tele-ultrasound to train novice scanners") to assess the effectiveness of tele-education using the Butterfly handheld ultrasound device when compared to in person education imaging devices, learning modules and assessments will be kept constant across experimental groups. This experiment aims to adapt the current ultrasound modules used by the University of Colorado Anschutz school of Medicine and Modern Human Anatomy program to formulate in depth modules that outline the following: Carpal Tunnel (wrist), Brachial Plexus (shoulder), and FAST "Focused Assessment with Sonography in Trauma". Additionally, participants will be provided an orientation module that will be completed prior to the live session. Participants will be divided into either the in-person group or virtual group and participate in a live session where participants go through each module with a trained instructor. Participants will be asked to complete a pre/post assessment to determine prior knowledge and the level of learning that took place during the session as well as participant satisfaction and confidence levels.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| In-Person ultrasound participants | Active Comparator | In-Person ultrasound participant's will receive ultrasound training that is guided by online modules (identical to virtual) with trained faculty in the same room with a ration of 4 students to 1 instructor. |
|
| Virtual ultrasound participants | Active Comparator | Virtual ultrasound participants will receive ultrasound training that is guided by online modules (identical to in-person) with trained faculty present in a private zoom classroom. Faculty will be rotating between breakout rooms and will share the same ratio of participants to staff. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Butterfly handheld ultrasound machine | Combination Product | Both arms of study will utilize the Butterfly ultrasound machine. Only the virtual learners will utilize zoom for their virtual education |
| Measure | Description | Time Frame |
|---|---|---|
| Comparison of participant assesment scores when asked to identify key features of the FAST and Carpal Tunnel between in person learners and virtual learners. | Scores are measured on a pass (1) or fail (0) grading system with a total number of 17 points per participant. An Anderson-Darling test will determine if the data is normally distributed. If the data demonstrates normal distribution, either a parametric analysis via a two-way ANOVA or non-parametric equivalent analysis via pairwise Mann-Whitney U will be performed to compare responses from the different groups. Further a Bran-Altman Test will be considered. | 10 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| Student comparative confidence levels in ultrasound between virtual learners and in-person learners. | Likert Scale measures participant's subjective opinion on a question. Five answer choices are provided on a scale of 0 to 5 with an extreme on both ends, a neutral choice and a middle ground answer for both ends of the spectrum. A higher score represents a greater degree of confidence in the material. Lower scores indicate little to no confidence in the material. |

| Student comparative satisfaction levels in ultrasound between virtual learners and in-person learners. | Likert Scale measures participant's subjective opinion on a question. Five answer choices are provided on a scale of 0 to 5 with an extreme on both ends, a neutral choice and a middle ground answer for both ends of the spectrum. Higher scores indicate high satisfaction levels with the learning modality. Low scores indicate that participant's did not enjoy the learning modality. | 1.5 hours |
