BACKGROUND: Sports-related concussions disproportionately affect young athletes. The primary objective of our study was to determine Illinois pediatricians' level of familiarity with state concussion legislation and with published consensus guidelines for sports concussion diagnosis and treatment. We also sought to determine pediatricians' knowledge regarding concussion management and comfort treating sports concussion patients. METHODS: This was a cross-sectional survey of pediatrician members of the Illinois Chapter of the American Academy of Pediatrics. RESULTS: Few general pediatricians (26.6%, n = 42) were "very familiar" or "somewhat familiar" with the recently passed Illinois state concussion legislation. Only 14.6% (n = 23) of general pediatrician respondents use concussion consensus guidelines in their practice. Pediatricians were generally very knowledgeable about concussions; only 5 out of 19 knowledge-based items were answered incorrectly by more than 25% of the study participants. CONCLUSIONS: General pediatricians are knowledgeable about concussions but most are not well aware of state concussion legislation and concussion consensus guidelines.
