Abbreviations: CI = confidence interval; TBI = traumatic brain injury.
*Visits with missing age were excluded. Numbers subject to rounding error.
†Persons who were hospitalized, died, or transferred to another facility were excluded.
§Includes falls of undetermined intent to maintain consistency with past data releases.
¶E-codes specify that the injury was unintentional but do not specify the actual mechanism of injury.
**Includes TBIs in which the intent was not determined as well as those due to legal intervention or war. Includes TBIs in which no mechanism was specified in the record. Does not include falls of undetermined intent.
††Per 100,000 population.
§§Estimates suppressed for the age groups 0–4 and 5–14 years because it is unclear whether children aged <10 years are able to form suicidal intent.
¶¶The relative standard error was >30% or the standard error = 0, the value of the estimate was considered unreliable and was not reported.
***Age-adjusted to the 2000 U.S. standard population (per 100,000 population).
†††Significant difference in rate compared to 2007 based on t-test (p<0.05). Only selected comparisons were tested for statistical significance.
