Supporting social emotional development, beginning at birth, can improve lifelong health. The American Academy of Paediatrics recommends 12 well-child visits between birth and age 3 years. Each well-child visit provides a unique opportunity to interact with and support families to promote social emotional development of children. Eighteen US paediatric practices joined a learning community to use improvement science to test and implement evidence-informed strategies that nurture parent-child relationships and promote the social emotional development of young children.Quality improvement methods were used to integrate 11 strategies into well-child visits between birth and age 3 years and measure the improvements with a set of outcome, process and balancing measures. Participation among the 18 paediatric practices was high with 72% of teams attending monthly webinars and 97% of teams attending the three learning sessions. Over 12 months, the percentage of children receiving age-appropriate social emotional development screens at participating practices' well-child visits increased from a baseline median of 83% to 93%.Current paediatric practice in the USA focuses primarily on cognitive and physical development, and paediatric providers are less familiar with established practices to screen for social emotional development and promote the caregiver-child relationship. This project suggests that improvement methods show promise in increasing the number of children who receive age-appropriate social emotional development screens or assessments at well-child visits.
