Reduce nonfatal physical assault injuries — IVP‑10 Data Methodology and Measurement

About the National Data

Data

Baseline: 496.7 emergency department visits for nonfatal physical assault injuries per 100,000 population occurred in 2017

Target: 277.9 per 100,000

Numerator
Number of initial hospital emergency department visits for nonfatal physical assault injuries.
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 non-linear. 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 nonfatal physical assault injury is defined as an injury from an act of nonfatal violence where physical force by one or more persons is used with the intent of causing harm, injury, or death to another person or an intentional poisoning by another person. Both confirmed and suspected assaults are included. 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 physical assault injury cases in the emergency department record. A detailed description of the methods for coding nonfatal injuries has been published elsewhere. Rates by race are not reported because multiple race data are not typically available from the emergency department records. Emergency department 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.
