A number of unique approaches are available to improve particular aspects of well child care, but there is no comprehensive plan for providing developmental and other preventive services in an efficient and effective manner. This project will produce a practical, authoritative physician guide to best office practices in well child care, including research-based, technology-driven strategies to achieve them. The investigators will consolidate information on the latest health care innovations and consult with pediatric experts in order to generate key concepts and specific strategies. The resulting guide will be disseminated to pediatric practices through the meetings and publications of the American Academy of Pediatrics, the National Initiative for Child Health Quality, and other national organizations and agencies. Project staff also will collaborate with members of a national, practice-based pediatric research network to develop plans for implementing best practices in physician offices and testing their feasibility. http://www.stanford.edu/
