HealthDay News — States with legislation on concussion had an increase in health care utilization for concussion-related care compared to states that didn’t, according to research published in JAMA Pediatrics.

Teresa B. Gibson, PhD, from Truven Health Analytics in Ann Arbor, Mich., and colleagues examined the effect of concussion laws on health care utilization rates in states with and without legislation. Data were collected for commercially insured children aged 12 to 18 years from all 50 states and Washington, D.C., from Jan. 1, 2006, through June 30, 2012.

The researchers found that states with legislation experienced a 92% increase in concussion-related health care utilization between academic school years 2008-2009 to 2011-2012; during the same period, states without legislation had a 75% overall increase in concussion-related health care utilization. Compared with prelegislation trends (2005 to 2009), in states without legislation the rates of treated concussion were 7, 20, and 34% higher in the 2009 to 2010, 2010 to 2011, and 2011 to 2012 schools years, respectively, after controlling for differences across states (all P < 0.01). Compared with states without laws, states with concussion laws demonstrated a 10% higher concussion-related health care utilization rate during the same period (P < 0.01).

“Concussion legislation has had a seemingly positive effect on health care utilization, but the overall increase can also be attributed to increased injury awareness,” the authors write.
