Confidence, knowledge, and performance improvements among all residents

Measure	All residents (n=33)
	Before mean (SD)	After mean (SD)	Delta mean (95% CI)
Confidence* simulation 1	2.85 (0.57)	3.36 (0.54)	0.51 (0.37 to 0.65)
Confidence simulation 2	3.15 (0.45)	3.39 (0.53)	0.24 (0.14 to 0.35)
Confidence—before simulation 1 to 4–6 months; (n=11)	2.91 (0.37)	3.50 (0.37)	0.59 (0.37 to 0.81)
Knowledge† simulation 1	69.52 (16.66)	81.90 (14.50)	12.38 (7.79 to 16.97)
Knowledge simulation 2	83.81 (15.35)	87.62 (13.90)	3.81 (0.12 to 7.50)
Knowledge—before simulation 1 to 4–6 months; (n=11)	68.83 (15.41)	83.93 (7.43)	15.10 (3.25 to 26.96)
Performance by TRACS‡ simulation 1–2 (n=33)	75.81 (14.53)	87.29 (11.73)	11.48 (6.54 to 16.43)

*Confidence measured as the average of eight, five-point Likert questions.

†Knowledge measured as % points of a multiple-choice assessment.

‡Performance measured as % points on the TRACS.
