The study will be coordinated by Vanderbilt University researchers on contract through AHRQ's Effective Health Care program. Data analysis will be performed by researchers at Vanderbilt, Kaiser Permanente of California, the HMO Research Network and i3 Drug Safety, as well as from FDA and AHRQ. The analysis will include all drugs currently marketed for treating ADHD. The study will analyze the risks of all the drugs as a whole, and risks of the drugs grouped by class.
The analysis will take about 2 two years to complete. Results are expected to be important not only to patients, their families and health care providers, but also to government insurance programs. Medicaid, Medicare, and the State Children's Health Insurance Program provide reimbursement for drugs prescribed for ADHD. This information could also be used to inform product labeling, which is used by health care providers when making treatment decisions.

About $1.3 billion was spent on those drugs in 2004, the study estimated. Adult use is also believed to be increasing.
