About the National Data

Data

Data Sources:  National Electronic Injury Surveillance System - All Injury Program (NEISS-AIP), CDC/NCIPC and CPSC; Bridged-race Population Estimates, CDC/NCHS and Census

Baseline: 8,620.6 emergency department visits for nonfatal unintentional injuries per 100,000 population occurred in 2017

Target: 7,097.8 per 100,000

Numerator
Number of initial hospital emergency department visits for nonfatal unintentional 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 data's 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 and evidence-based prevention strategies exist for many of the leading causes of unintentional injuries.

Methodology

Methodology notes

NEISS does not use ICD codes. However, reporters are given extensive training and report any unintentional injury cases in the emergency department record. Data 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. For census years (e.g., 2010), population counts enumerated as of April 1 are used. For all other years, population estimates as of July 1 are used. 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 year are updated annually, which means that rates prior to the update may be different.

History

Comparable HP2020 objective
Modified, which includes core objectives that are continuing from Healthy People 2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People 2020 objective IVP-1.3 in that the data source for objective IVP-1.3 was the National Hospital Ambulatory Medical Care Survey (NHAMCS), while the data source for this objective is the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP). This objective tracks emergency department visits for nonfatal unintentional injuries, while the Healthy People 2020 objective IVP-1.3 tracks emergency department visits for nonfatal injuries.
