Abstract
BACKGROUND: Crisis resource management (CRM) skills are a set of nonmedical skills required to manage medical emergencies. There is currently no gold standard for evaluation of CRM performance. A prior study examined the use of a global rating scale (GRS) to evaluate CRM performance. This current study compared the use of a GRS and a checklist as formal rating instruments to evaluate CRM performance during simulated emergencies. METHODS: First-year and third-year residents participated in two simulator scenarios each. Three raters then evaluated resident performance in CRM using edited video recordings using both a GRS and a checklist. The Ottawa GRS provides a seven-point anchored ordinal scale for performance in five categories of CRM, and an overall performance score. The Ottawa CRM checklist provides 12 items in the five categories of CRM, with a maximum cumulative score of 30 points. Construct validity was measured on the basis of content validity, response process, internal structure, and response to other variables. T-test analysis of Ottawa GRS scores was conducted to examine response to the variable of level of training. Intraclass correlation coefficient (ICC) scores were used to measure inter-rater reliability for both scenarios. RESULTS: Thirty-two first-year and 28 third-year residents participated in the study. Third-year residents produced higher mean scores for overall CRM performance than first-year residents (P < 0.05), and in all individual categories within the Ottawa GRS (P < 0.05) and the Ottawa CRM checklist (P < 0.05). This difference was noted for both scenarios and for each individual rater (P < 0.05). No statistically significant difference in resident scores was observed between scenarios for both instruments. ICC scores of 0.59 and 0.61 were obtained for Scenarios 1 and 2 with the Ottawa GRS, whereas ICC scores of 0.63 and 0.55 were obtained with the Ottawa CRM checklist. Users indicated a strong preference for the Ottawa GRS given ease of scoring, presence of an overall score, and the potential for formative evaluation. CONCLUSION: Construct validity seems to be present when using both the Ottawa GRS and CRM checklist to evaluate CRM performance during simulated emergencies. Data also indicate the presence of moderate inter-rater reliability when using both the Ottawa GRS and CRM checklist.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
