Objective
To describe a single-institution pilot study regarding prevalence and risk factors for delirium in critically ill children.
Design
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 (CAPD).
Setting
This study took place in the pediatric intensive care unit (PICU) at an urban academic medical center.
Patients
99 consecutive patients, ages newborn to 21 years.
Intervention
Subjects underwent a psychiatric evaluation for delirium based on the DSM-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.
Conclusions
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.
