Measure of learning
respiratory distress
The primary outcome was how much the learning results improved in the identification of breathing problems in children. Learning was measured using the same Webropol e-Test that was sent to the participants via e-mail on three separate occasions (baseline, final and long-term memory tests). The test was time-constrained (15 min) and consisted of 10 multiple-choice questions: five theoretical questions and five video clips of children with respiratory distress. The number of correct response alternatives was one or more in each question: Every correct choice accounted for plus 2 points and every wrong choice for 1 minus point. The maximum score was plus 28 points, and the minimum was minus 26 points.Learning efficacy was defined as the difference between the final and baseline test scores.
