Risk Factors of Delirium in Children in Pediatric Intensive Care Unit

ABSTRACT

Objectives: To determine the prevalence of delirium and its risk factors among children admitted to a Pediatric intensive care unit (PICU). Method: A descriptive study in which consecutive patients admitted to the PICU over a period of 12 months were screened daily for delirium using the Cornell Assessment of Pediatric Delirium (CAPD) score. Treatmentrelated and demographic variables were collected and analyzed. The statistically significant risk factors for delirium were analyzed by multivariable logistic regression for independent associations. Results: Among the 476 screened patients, 96 (20.2%) developed delirium. The independent risk factors associated with the development of delirium were respiratory failure (P<0.001), administration of benzodiazepines during PICU stay (P<0.001), and presence of multiple (?2) risk factors for delirium (P<0.001). The mean length of PICU stay was significantly higher among delirious subjects with P<0.001. Conclusion: Delirium is a frequent complication in critically ill children, and recognition of associated factors may assist in early diagnosis and focussed management.
