About the National Data

Data

Baseline: 26.3 nonfatal firearm-related injuries per 100,000 population occurred in 2015

Target: 10.1 per 100,000

Numerator
Number of nonfatal firearm-related cases treated in U.S. hospital emergency departments (EDs).
Denominator
Number of persons.
Target-setting method

Minimal statistical significance

Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because the trend was moving away from the desired direction. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because it was a statistically significant improvement from the baseline.

Methodology

Methodology notes

A firearm-related injury is defined as a penetrating injury or gunshot wound from a weapon using a powder charge to fire a projectile. NEISS uses external cause of injury codes and follows guidelines consistent with coding guidelines in the ICD 9-CM. NEISS coders are given extensive training and report any gun-related injury cases in the emergency department record. Victims may also have other types of injuries, but if the incident involved a gun, it is included. Coders also attempt to capture data on intent, when appropriate information is provided in the medical record. Race data are not reported because they are not typically available from ED records. ED visit rates are calculated using the new bridged-race postcensal population estimates of the resident population of the United States for the data year involved. Population counts enumerated as of April 1st are used for census years (e.g., 2010). Population estimates as of July 1st are used for all other years. Intercensal population estimates are used in rate calculations for the years between censuses (e.g., 1991–1999, 2001–2009). Please note that postcensal population estimates for years after the last census are updated annually, which means that rates prior to the update may be different.
