Injury

  • A higher percentage of parents of children with attention-deficit/hyperactivity disorder reported non-fatal injuries (4.5% vs. 2.5% for healthy children). [Read article]
  • Children with ADHD, compared to children without ADHD, were more likely to have major injuries (59% vs. 49%), hospital inpatient (26% vs. 18%), hospital outpatient (41% vs. 33%), or emergency department admission (81% vs. 74%). [Read article]
  • Data from international samples suggest that young people with high levels of attentional difficulties are at greater risk of involvement in a motor vehicle crash, drinking and driving, and traffic violations. [Read article]

 

Economic Cost

  • Using a prevalence rate of 5%, the annual societal ‘‘cost of illness’’ for ADHD is estimated to be between $36 and $52 billion, in 2005 dollars.  It is estimated to be between $12,005 and $17,458 annually per individual.  [Read article]
  • There were an estimated 7 million ambulatory care visits for ADHD in 2006. [Read article ]
  • The total excess cost of ADHD in the US in 2000 was $31.6 billion.  Of this total, $1.6 billion was for the treatment of patients, $12.1 billion was for all other health care costs of persons with ADHD, $14.2 billion was for all other health care costs of family members with ADHD, and $3.7 billion was for the work loss cost of adults with ADHD and adult family members of persons with ADHD. [Read article]
  • ADHD creates a significant financial burden regarding the cost of medical care and work loss for patients and family members. The annual average direct cost for each per ADHD patient was $1,574, compared to $541 among matched controls. The annual average payment (direct plus indirect cost) per family member was $2,728 for non-ADHD family members of ADHD patients versus $1,440 for family members of matched controls. [Read article]
  • Across 10 countries, it was projected that ADHD was associated with 143.8 million lost days of productivity each year.  Most of this loss can be attributed to ADHD and not co-occurring conditions. [Read article]
