title: Outpatient rehabilitation utilization and medical expenses in children aged 0-7 years with ADHD: analyses of population-based national health insurance data.
abstract: Medical costs of attention-deficit/hyperactivity disorder (ADHD) are substantial and have a large impact on the public health system. The present study presents information regarding outpatient rehabilitation care usage and medical expenditure for children with ADHD. A cross-sectional study was conducted by analyzing data from the Taiwan National Health Insurance claims database for the year 2009. A total of 6643 children aged 0-7 years with ADHD (ICD-9-CM codes 314.0x: attention deficit disorder, 314.00: attention deficit disorder without hyperactivity, or 314.01: attention-deficit disorder with hyperactivity) who had used outpatient rehabilitation care were included in the analyses. Results showed that the mean annual rehabilitation care was 22.24 visits. Among the care users, 76% of patients were male, and 24% were female. More than half of the children with ADHD had comorbid mental illnesses as well. A logistic regression analysis of outpatient rehabilitation expenditure (low vs. high) showed that of those children with ADHD, those aged 0-2 years tended to incur more medical costs than those aged 6-7 years. Other factors such as frequency of rehabilitation visits, hospital medical setting and ownership, location of medical care setting, and types of rehabilitation were also significantly correlated with medical expenditure. The results from this study suggest that health care systems should ensure accurate diagnosis and measurement of impairment to maintain appropriate and successful management of rehabilitation needs for children with ADHD.
