Estimates are considered unreliable. Data preceded by an asterisk have a relative standard error (RSE) of 20%–30%. Data not shown have an RSE of greater than 30%.


Intent and mechanism of injury are based on the first-listed external cause of injury code (E code). Intentional injuries include suicide attempts and assaults. See Appendix II, External cause of injury and Table VII for a listing of E codes.


Estimates for 2005–2006 were limited to those visits that were initial visits for the condition. This was determined using an imputed variable indicating that the visit was or was not the initial visit. Limiting the estimates to initial visits decreases the total number of injury-related visits by 8.6% for 2005–2006. No similar variable indicating initial visits was available for 1995–1996 or 1999–2000 data. Therefore, 2005–2006 estimates are not directly comparable with 1995–1996 and 1999–2000 estimates.


Includes all injury-related visits not shown separately in table including those with undetermined intent (1.0% in 2005–2006) and insufficient or no information to code cause of injury (11.7% in 2005–2006).


Rates are age-adjusted to the year 2000 standard population using six age groups: under 18 years, 18–24 years, 25–44 years, 45–64 years, 65–74 years, and 75 years and over. See Appendix II, Age adjustment.


Includes unintentional injury-related visits with mechanism of injury not shown in table.

NOTES: An emergency department visit was considered injury related if the physician’s diagnosis was injury related ( ICD–9–CM 800–909.2, 909.4, 909.9–994.9, 995.50–995.59, and 995.80–995.85) or an external cause of injury code was present ( ICD–9–CM E800–E869, E880–E929, and E950–E999). Visits with a first-listed diagnosis or external cause code describing a complication or adverse effect of medical care are excluded. For more information on injury-related visits, see Bergen G, Chen LH, Warner M, Fingerhut LA. Injury in the United States: 2007 Chartbook. Hyattsville, MD: NCHS. 2008. Available from: http://www​​/data/misc/injury2007.pdf. Rates were calculated using estimates of the civilian population of the United States including institutionalized persons. The population estimates used are the same used for rates calculated for the National Hospital Discharge Survey. Population data are from unpublished tabulations provided by the U.S. Census Bureau. Rates prior to 2001 were calculated using population estimates based on the 1990 census. Rates for 2005–2006 were calculated using postcensal population estimates based on the 2000 census. Estimates and definitions have been revised and differ from previous editions of Health, United States.
