Use of formal developmental screening tools in the pediatric medical home improves early identification of children with developmental delays and disorders, including Autism Spectrum Disorders. A pilot study evaluated the impact of an academic detailing module in which trainers visited 43 pediatric primary care practices to provide education about implementing developmental screening tools in well-child services. Attendees responded to a post presentation survey stating that they planned to implement screening in their practices. Medicaid billing data showed an increase in the state’s overall rate of screening. An audit of medical charts in five practices that received the training and five that did not showed higher screening rates in practices that received the training as well as higher rates after the training than before. These pilot study results indicate the potential of academic detailing as an effective strategy for improving rates of developmental screening.
