Table 3.

Means (95% Cl) of percentages of correct answers in the MCQ test before (pre-MCQ) and after (post-MCQ) in the ISS and OSS groups

Descriptive statistics
MCQ test
Per cent correct
Simulation intervention Pre-MCQ mean* (start of training day) Post-MCQ mean* (end of training day) Mean difference*†
ISS 69.4 (65.4 to 73.4) 82.6 (79.3 to 85.8) −0.02 (−2.13 to 2.09) p=0.98
OSS 70.6 (66.0 to 75.2) 83.3 (80.4 to 86.1)

*Based on generalised estimating equations to account for potential correlation within teams.

†Adjusted for pre MCQ (ANCOVA).

ANCOVA, analysis of covariance; ISS, in situ simulation; MCQ, multiple choice question (range: 0–100%); OSS, off-site simulation.
