Data and Methods

• Age-adjusted death rates from National Vital
  Statistics System (NVSS)
• Kendalls Tau correlation coefficient to identify
  noteworthy trends
• Causes of death are coded and classified as per
  system of International Classification of
  Diseases, Tenth Revision (ICD-10)
• Injury deaths limited to ICD-10 codes U01-U03,
  V01-Y36, Y85-Y87, or Y89.

Data and Methods, continued

• Causes of death are further grouped following
  parameters of the External cause-of-injury
  mortality matrix (E.C. Matrix).
• Jointly developed by the Injury Control and
  Emergency Health Services section of the American
  Public Health Association (APHA) and the
  International Collaborative Effort on Injury
  Statistics
• E.C. Matrix shows injury data by both mechanism
  and intent of death.

Summary

• The following trends were identified as
  noteworthy
• (per race and origin category)
• Hispanic
• decreasing unintentional injury mortality
• decreasing firearm-related suicide
• Non Hispanic White
• increasing unintentional injury mortality
• increasing motorcycle-related injury mortality
• decreasing unspecified role motor vehicle traffic
  mortality
• increasing poisoning mortality
• increasing mortality from falls
• Non Hispanic Black
• decreasing unintentional injury mortality
• decreasing suicide mortality
• decreasing motor vehicle traffic mortality
• decreasing firearm-related suicide
• increasing firearm-related homicide mortality

Concluding remarks

• More research needed to determine effect of
  decreases in unspecified role in MVT death upon
  other MVT trends identified (e.g.
  motorcycle-related mortality in nH white).
• More research needed to determine effect of
  decreases in certificates closed as pending
  investigation upon other trends identified
  (poisoning deaths comes to mind).
