Aims & Objectives:

Reports on increasing incidence rates of delirium in critically ill children are reason for concern. We evaluated the measurement properties of the peadiatric delirium component (PD-scale) of the SOS-PD scale.

In a multicenter prospective observational study in four Dutch PICUs, patients aged ≥3 months and admitted for ≥48 hours were assessed with the PD-scale thrice daily. Criterion validity was assessed: if the PD-scale score was 4 or higher, a child psychiatrist clinically assessed the presence or absence of PD diagnosis according to the DSM-IV. In addition, the child psychiatrist assessed a randomly selected group to establish the false-negative rate. The construct validity was assessed by calculating the Pearson correlation (rp) coefficient between the PD-scale and the CAP-D scores. Interrater reliability was determined by comparing paired nurse and researcher PD-scale assessments and calculating the intraclass correlation coefficient (ICC).

Four hundred eighty-five patients with a median age of 27.0 months (IQR 8–102) were included, of whom 48 patients were diagnosed with delirium by the child psychiatrist. The PD-scale had an overall sensitivity of 92.2% and a specificity of 96.9% compared to the psychiatrist diagnosis for a cut-off score of 4 points. The correlation (rp) between the PD-scale and the CAP-D scores was 0.89 (CI 95% 0.82–0.93; p<0.001). The ICC of 75 paired nurse-researcher observations was 0.99 (95% CI 0.98–0.99).

The PD-scale shows a good validity for early screening of PD. It can be validly and reliably used by nurses to assess presence of delirium in critically ill children.
