Table 5 List of hypotheses to be tested
Type of hypothesis | Specification of the hypothesis |
|---|---|
Primary (behavioral analysis) | Physicians in the game-based training group will under-triage a smaller proportion of patients than those in the usual education group |
Secondary (outcome analysis) | Physicians in the game-based training group will have fewer patient outcomes (i.e., 30-day mortality and readmissions, loss of functional independence) than those in the usual education |
Secondary (outcome analysis) | Physicians in the game-based training group will over-triage a similar proportion of minimally injured patients compared to those in the usual education group |
Secondary (mediation) | Under-triage will mediate the effect of the intervention on patient outcomes |
Exploratory (heterogeneity of treatment effect) | [1] The intervention will have the same effect on males as on female trial participants [2] The intervention will have the same effect on White as on non-White trial participants [3] The intervention will have a greater effect on trial participants who express positive attitudes to game-based learning before enrollment compared to those who do not have positive attitudes [4] Trial participants in the game-based training group who use Night Shift 2024 for greater than 2 h will under-triage a smaller proportion of severely injured patients than those who use the game for less than 2 h [5] The proportion of patients under-triaged by trial participants will be lower immediately after exposure to the intervention (i.e., in the first 30 days) compared to late post-exposure period (i.e., 30–89 days) [6] Trial participants with greater parameters of compliance on SONAR (the experimental tool to measure determinants of physicians’ decision making) will under-triage a smaller proportion of severely injured patients than those with lower parameters of compliance |
