  1. Based on correction for verification bias, only the first psychiatric assessment and the corresponding pediatric delirium (PD)-assessment were evaluated; 42 patients were diagnosed with delirium. In comparison to Table 3, the first psychiatric assessment in 7 patients was performed in the framework of random assessment and they were not diagnosed as delirious. During the pediatric ICU admission a second psychiatric assessment was performed in the case of suspected delirium. These assessments were excluded in the analysis for correcting for verification bias
