Teaching first or teaching last: does the timing matter in simulation-based surgical scenarios?
Participants who received instruction after simulated scenarios achieved higher mean knowledge scores than those who received instruction before simulated scenarios. Cognitive overload, stress, or activation of prior knowledge could all be involved as causal mechanisms.
Considering the risk of inducing a summation of the reactions, and thereby a generalized allergic reaction, when applying an extra allergen load on the limited surface of the small arm, we conclude that the results of this study justify using single prick test, at least in the youngest age group and probably when testing children of all ages.
