Pediatric primary care providers report limited training and tools to manage concussion. We developed a learning community intervention for a large independent pediatric practice association affiliated with a university hospital to standardize concussion management and improve the use of consensus-based guidelines. The learning community included in-person and online didactics, followed by a web-based reinforcement platform to educate and train clinicians on our treatment algorithm and decision support tools. Chart reviews before and after the intervention demonstrated significant increases in the use of standardized symptom rating scales (19.6% to 69.3%; P < .001), balance assessment (2.3% to 37.6%; P < .001), and scheduled follow-up (41.8% to 61.2%; P < .001), with an increase in delivery of our entire best practice bundle from 3.5% to 28.1% (P < .001). A multimodal educational intervention can effect change among pediatric primary care providers and help align their management practices with consensus-based guidelines.
