Patients with attention deficit hyperactivity disorder (ADHD) are prone to injury and frequently require treatment with hospital admission. This study aimed to evaluate the risk of injuries requiring hospitalization among children and adolescents with and without ADHD and assess the effects of medication on the risk reduction in patients with ADHD. This is a retrospective population-based cohort study by using data from the Taiwan National Health Insurance Research Database. We compared 4658 6-18 year-old ADHD patients with 18 632 sex-, age-, and index day-matched non-ADHD controls between 2005 and 2012. Both groups were followed until the end of 2013 to compare the risk of injuries requiring hospitalization. Cox regression analysis was performed to determine the hazard ratio (HR) with 95% confidence intervals (CI) after adjusting for confounders. Children and adolescents with ADHD had a significantly higher risk of injuries requiring hospitalization than the non-ADHD controls (HR = 1.39, 95% CI = 1.12-1.72), and a higher risk was especially observed in the male and adolescent subgroups. In ADHD patients, long-term users of ADHD medication were associated with a lower risk of injuries requiring hospitalization than nonusers (HR = 0.51, 95% CI = 0.30-0.85). Healthcare providers should be aware of the potential risk of injury in patients with ADHD and highlight the importance of the duration and compliance with medication treatment. © 2022 The Authors.
