Methodology Notes

The Traumatic Brain Injury (TBI) definition is based on the Barell Matrix. TBI types 1, 2, and 3 are included. The increased use of 959.01 was accompanied by a corresponding drop in the use of 854. Thus, to avoid underestimating TBIs, cases coded as 959.01 were also included.

Those who died, were admitted to the same or transferred to another hospital, or who have an unknown disposition were excluded.

FOR SINGLE DATA YEARS: Emergency department visit rates are calculated using the July 1 estimates of the civilian population from the Vintage matching the data year for the postcensal period based on the 2000 census. For example, July 1, 2007 civilian population estimates from Vintage 2007 are used as the denominator for 2007 rates. Rates for 2010 are also calculated using the July 1 estimates based on the 2000 census.

Rates by geographic location and health insurance status are for the civilian noninstitutionalised population.
