Abstract
It is true that the sample size for our cohort was previously calculated by Émond et al.1 to determine the incidence of delirium. However, the logistic regression analysis used in our study included the total 338 patients and not only the 41 patients with delirium. In addition, we reported a power calculation showing that with 338 patients, we had 80% chance of finding an odd-ratio (OR) of at least 1.7 for a predictor of delirium, considering a baseline probability of 0.12 of delirium (41 cases). According to Chen et al.2 an OR of 1.7 is considered a small effect size by Cohen references, so we had sufficient power in our study to detect even a small effect size. It is also true that we did not have the power to examine the relationship between diagnoses and delirium in our study. However, in an ED setting, this relationship has not been clearly established.
