To describe a single-institution pilot study regarding prevalence and risk factors for delirium in critically ill children.
A prospective observational study, with secondary analysis of data collected during the validation of a pediatric delirium screening tool, the Cornell Assessment of Pediatric Delirium.
This study took place in the PICU at an urban academic medical center.
Ninety-nine consecutive patients, ages newborn to 21 years.
Subjects underwent a psychiatric evaluation for delirium based on the Diagnostic and Statistical Manual IV criteria.
Measurements and Main Results:
Prevalence of delirium in this sample was 21%. In multivariate analysis, risk factors associated with the diagnosis of delirium were presence of developmental delay, need for mechanical ventilation, and age 2–5 years.
In our institution, pediatric delirium is a prevalent problem, with identifiable risk factors. Further large-scale prospective studies are required to explore multi-institutional prevalence, modifiable risk factors, therapeutic interventions, and effect on long-term outcomes.
