Cost effectiveness of optimal treatment of ADHD in Israel: a suggestion for national policy.

There are well known behavioral complications of ADHD at adulthood such as learning difficulties resulting in lower education attainments; increased rate of car and other accidents; substance abuse; misconduct and imprisonment. These complications can be prevented or alleviated by effective treatment. In this study we calculated the economic burden of ADHD among adults in Israel and the cost of diagnosing and treating ADHD from childhood to adulthood. We then obtained the cost-benefit ratio of the treatment. The data were calculated using accepted estimations of prevalence and cost for the Israeli population assuming a prevalence of 4% among adults which is based on the ADHD prevalence among school age children. The estimated cost per person with ADHD due to lower education attainment, higher involvement in crime and car accidents and more drug abuse is 289,969 USD and the estimated cost for optimal treatment is 41,667 USD. Hence, the benefit cost ratio is 7.02 and, assuming only 50% success of treatment, it is 3.51, still a very high cost benefit ratio. Since early diagnosis and appropriate treatment of ADHD is very effective in reducing the various symptoms and complications at adulthood thus enabling a better education and higher income, it seems important to diagnose and offer comprehensive treatment to children with ADHD. Moreover, it seems equally important to continue treatment at adulthood.
