Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: normal model patient<br>Images of the ultrasound window were captured to disk and later evaluated by an expert in emergency medicine. In this study, the FAST examination was measured to the perihepatic space (also called Morison's pouch or the hepatorenal recess), perisplenic space, pericardium, and the pelvis. | Device: SonoScape<br>* Ultrasonography device<br>* Other names: SonoScape S6 Portable Ultrasound Machine;|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Tests of Knowledge of the FAST Examination | knowledge-based measures used to evaluate participants' knowledge of FAST-examination-related concepts (Survey) | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| FAST Performance Test | The performance test required participants to conduct a FAST examination on two model patients (one normal, one ascites positive). No help or feedback was given to the participants. | 1 day | 
| Window acquisition time | Identification of FAST Window Quadrants and Diagnostic Interpretation of FAST Windows. The window acquisition time was measured with a stopwatch and represented the period between first contact of the probe with the model patient's body and when the participant said stop to indicate an adequate window or the participant's judgment that he or she could not acquire the window. | 1 day | 
| Window quality | For each acquired window, an expert evaluated the quality of the window. The window was rated as excellent, fair, poor, or other. Other captured situations where the window acquired was nondiagnostic. Window quality was dichotomized into two categories, excellent or not excellent, and subsequent analyses examined the number of participants that acquired excellent windows by quadrant (perihepatic space (also called Morison's pouch or the hepatorenal recess), perisplenic space, pericardium, and the pelvis and suprapubic quadrant) and patient type (normal, positive). | 1 day | 
| Diagnostic accuracy | For each acquired window, the participant rendered a diagnosis of that window. An expert evaluated the quality of the diagnosis. The diagnosis was rated as correct, incorrect, or other. Other captured situations where the window acquired was nondiagnostic. For analysis purposes, diagnostic accuracy was dichotomized into two categories, correct or not correct, and subsequent analyses examined the number of participants that interpreted the window correctly by quadrant (perihepatic space (also called Morison's pouch or the hepatorenal recess), perisplenic space, pericardium, and the pelvis and suprapubic quadrant) and patient type (normal, positive). | 1 day |
