Attention-deficit/hyperactivity disorder (ADHD) is a commonly occurring behavioral disorder among children. Community-based physicians are often the primary providers of services for children with ADHD. A set of consensus guidelines has been published by the American Academy of Pediatrics that provides best-practice diagnostic procedures for primary-care physicians. These recommendations emphasize the importance of using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria as the basis for making an ADHD diagnosis and conducting systematic follow-up, including the collection of parent and teacher ratings scales to quantitatively assess response to treatment. Although these recommendations have been widely disseminated and their adoption actively promoted, guideline adherence, in general, is known to be poor. Two types of intervention models, ancillary service and office systems modification, have been proposed to promote adoption of evidence-based ADHD practice in primary-care settings. The present article reviews the efficacy of these intervention models, and discusses the cost and sustainability of each model as related to feasibility of intervention dissemination.
