Physicians in this arm of the trial will be asked to play Night Shift, an adventure video game, for one hour.

Physicians in this arm of the trial will be asked to use myATLS, an app designed by the American College of Surgeons to serve as an adjunct to the ATLS course, and Trauma Life Support MCQ Review, an app designed to help students prepare for the ATLS exam. They will be asked to spend at least one hour on the combined tasks.

Night Shift is an adventure video game with the transformational goal of teaching physicians key characteristics of patients with non-representative severe injuries - injuries classified by the American College of Surgeons as life-threatening or critical but that do not fit the archetype of injuries typically requiring treatment at a trauma center. Players take on the persona of Andy Jordan, a young emergency physician who moves home after the disappearance of his estranged grandfather (Robert Jordan) and takes up a job in the local Emergency Department (ED). In the preamble, players learn they have two explicit objectives. First, they must diagnose and treat patients who present to their ED. Second they must solve the mystery of Robert's disappearance: was he murdered or has he simply chosen to disappear?

Physicians in both arms of the study will be randomized to complete one of two versions of a virtual simulation: a control version and a cognitive load version. They will complete the simulation upon completion of the intervention, ideally within one month of enrollment.

The virtual simulation replicates the environment of the ED. Physicians have to manage 10 patients that appear concurrently, while also responding to a series of audio-visual distractors. Specifically, they must provide information on whether they will admit, transfer, or discharge the patients home. The investigators will calculate an under-triage rate for each physician (the number of simulated patients with severe injuries not transferred to a trauma center), summarize the under-triage rate by group (Night Shift v. educational control), and will compare the difference in those rates.

As described above, participants will complete either a control or cognitive load version of the virtual simulation upon completion of the intervention, ideally within one month of the enrollment. As a secondary outcome measure, the investigators will assess the difference in under-triage rates of physicians who complete the simulation under control and cognitive load conditions, by intervention type.
