Highlights
• Introduces the External Cause of Injury Mortality Matrix for ICD-10
•Presents data by age, race, sex and state
•Nature of injury data•Detailed data on poisoning deaths•Deaths with natural underlying cause
and mention of external cause

Intent and Mechanism of Death• ICD codes for external causes are two-
dimensional, indicating both intent and mechanism
• Intent•the purpose or manner of the injury, i.e.,
unintentional, intentional (suicide or homicide), or undetermined
•Mechanism of death •the vector that transfers energy to the body
(e.g., firearm, poisoning, motor vehicle)

External Cause of Injury Mortality Matrix•Development
•Collaboration involving ICE on Injury Statistics
•Recently modified and updated to be consistent with ICD-10
•Rationale•Provide a standard framework to facilitate
national and international comparability•Present information by both mechanism and
intent

Nature of Injury
•Not used as underlying cause of death (UC)• UC is the external cause that precipitated the
injury• Nature of injury is coded with multiple cause
data
•Nature of injury codes are two-dimensional• Type of injury sustained• Body site injured

Poisoning Mortality
• Poisoning deaths are identified in 3 ways• As the underlying external cause of
death – 22,242 deaths• As the nature of injury – 25,807 deaths• Underlying cause classified to mental
and behavioral disorders due to psychoactive substance use (F-codes) – 8,558 deaths

Natural underlying cause with mention of external cause
•In 2001, 36,753 deaths with natural UC had mention of an external cause•Most were cardiovascular diseases,
pneumonitis, cancer, Alzheimer’s disease and COPD
•Some are likely certification errors•E.g., external cause improperly listed in
Part II
![Page 21: Presenting and Analyzing Injury Mortality Data in the U.S.](https://reader035.fdocuments.us/reader035/viewer/2022062521/56812d3c550346895d923fcf/html5/thumbnails/21.jpg)
Natural underlying cause with mention of external cause
•More than 70% of these deaths had mention of ICD-10 codes W80 and X59 •W80 = Inhalation and ingestion of other
objects causing obstruction of respiratory tract•Typically mentioned with stroke or
pneumonitis as the UC
•X59 = Exposure to unspecified factor•Usually involves a fracture without
specification of external cause•Typically mentioned with heart disease,
cancer, stroke or COPD as the UC

Interpreting Injury Mortality Data
•Dependent on the accuracy of the cause of death reported on the death certificate
•Specificity is a problem•With regard to the external cause•With regard to the nature of injury
•Records still pending investigation at file closure
![Page 23: Presenting and Analyzing Injury Mortality Data in the U.S.](https://reader035.fdocuments.us/reader035/viewer/2022062521/56812d3c550346895d923fcf/html5/thumbnails/23.jpg)
Future Developments
• ICE on Injury Statistics•Adapting the Barell Matrix for ICD-10
and mortality data•Selection of main injury
•National Violent Death Reporting System (NVDRS)
