Injuries to children with attention deficit hyperactivity disorder.

OBJECTIVES: To determine differences between hospital admitted injuries to children with preinjury attention deficit hyperactivity disorder (ADHD) and injuries to those with no preinjury conditions (NO).
DESIGN: Comparative analysis, excluding fatalities, of ADHD patients (n = 240) to NO patients (n = 21 902), 5 through 14 years of age. OUTCOME MEASURES: Demographics, injury characteristics, length of stay, admission to the intensive care unit, surgical intervention, disability, and disposition at discharge. DATA SOURCE: Retrospective review of charts submitted by more than 70 hospitals participating in the National Pediatric Trauma Registry between October 1988 and April 1996.
RESULTS: Compared with the NO children, the children with ADHD were more likely to be boys (87.9% vs 66.5%), to be injured as pedestrians (27.5% vs 18.3%) or bicyclists (17.1% vs 13.8%), and to inflict injury to themselves (1.3% vs 0.1%). They were more likely to sustain injuries to multiple body regions (57.1% vs 43%), to sustain head injuries (53% vs 41%), and to be severely injured as measured by the Injury Severity Score (12.5% vs 5.4%) and the Glasgow Coma Scale (7.5% vs 3.4%). The ADHD mean length of stay was 6.2 days versus 5.4 in the NO group. In both groups, 40% had surgery, but the ADHD children were admitted more frequently to the intensive care unit (37.1% vs 24.1%). The injury led to disability in 53% of the children with ADHD vs 48% of the NO children. Children with ADHD with any disability were twice as likely to be discharged to rehabilitation/extended care than were the NO children.
CONCLUSIONS: Injured children with ADHD are more likely to sustain severe injuries than are children without ADHD. More research is needed to identify prevention efforts specifically targeted at this population.
