WISQARS:


Web-based Injury Statistics Query and
Reporting System
Interactive database system that provides
customized reports of injury-related data useful
for research and for making informed public
health decisions.
http://www.cdc.gov/ncipc/wisqars/
Data Sources:
Mortality Data
Official state death certificates
–
•
–
Compiled by all the states and submitted to the National
Center for Health Statistics for the entire country.
Population data come from the Bureau of Census.
Morbidity Data
–
Estimates based on weighted data from the U.S.
Consumer Product Safety Commission's (CPSC) National
Electronic Injury Surveillance System (NEISS).
http://www.cdc.gov/ncipc/wisqars/
Limitations:
WISQARS does not:

–
–

Provide date earlier than 1981
Provide non-injury data, except what is available on
the leading causes of death reports.
The data can be selected down to the state
level, but you cannot select a specific county or
individual tribes.
http://www.cdc.gov/ncipc/wisqars/
Coding Data:
Injury death data are assigned an external cause of
death code called “E-codes”.

Data from 1979-1998 are coded according to the 9th
Revision of the International Classification of Diseases
(ICD-9)
Starting with1999, deaths are coded with the 10th revision,
or ICD-10.
–
–

The ICD-10 has a new coding scheme that is different than
the old e-codes, so it is not valid to combine 1999 data with
earlier years at this time.

WISQARS Reports:



Fatal Injury Data
Non-Fatal Injury Data
Violent Death Data (new and limited)
http://www.cdc.gov/ncipc/wisqars/
WISQARS Reports:
WISQARS Fatal Injury Data:




Fatal Injury Reports
Leading Causes of Death Reports
Years of Potential Life Lost (YPLL)
Fatal Injury Mapping (New)
Fatal Injury Reports:
Provides tables of total numbers of injury
deaths and rates per 100,000 population.
You can request a report to list deaths by


–
–
–
–
–
–
Cause and intent of injury
State of residence
Race
Sex
Age
Year
http://www.cdc.gov/ncipc/wisqars/
Leading Causes of Death Reports :





Compute the leading causes of death.
Tables show the impact of a particular cause
of death
Highlight the role that injuries play in mortality
at different age groups.
Report of leading cause of death report by
state of residence, race, sex, year or
combined years, and number of causes such
as 10 leading causes of death.
Can select only injuries and create a leading
cause of injury death chart.
http://www.cdc.gov/ncipc/wisqars/
Years of Potential Life Lost (YPLL) :




Measure of premature mortality (early death).
YPLL provides insight into the impact of
injury-related causes of death compared to
other causes of death.
YPLL is most commonly calculated as the
number of years lost before age 65
“65 – Age of Death = YPLL”
YPLL can be reported by state of residence,
race, sex, and year or combined years.

Fatal Injury Mapping (New):


Interactive mapping module for
fatal injury data
Can map down to County level
http://www.cdc.gov/ncipc/wisqars/
Small Numbers:
American Indian/Alaska Native population
numbers are small

–
You may need to combine years of data to get a
more accurate picture
The NCHS considers any rate based upon
fewer than 20 deaths to be an unstable rate.

–
Having larger numbers to base the rate on gives you
more confidence that the rate is representative.
http://www.cdc.gov/ncipc/wisqars/
Small Numbers:
EXAMPLE - drowning deaths among Alaska Natives during 1999

–
–
–
16 deaths and a rate of 17.3 per 100,000.
Because there were fewer than 20 deaths, this rate is considered
unstable.
To make this information more useful, you would need to combine at
least two years of data.

WISQARS shows unstable rates colored white with an asterisk (*).

The Leading Causes of Death report and YPLL will work best for
Native Americans by combining years of data,
–
–
–
Three years: 1996, 1997, and 1998.
This will give more numbers to look at.
For Fatal Injury Reports, if states are chosen, then combining 3 years of
data may also be needed depending on the injury cause.
http://www.cdc.gov/ncipc/wisqars/
Example:
* Rates based on 20 or fewer deaths may be unstable. Use with caution.
WISQARS Non-Fatal Data:


Non-Fatal Injury Reports
Leading Causes of Death Reports
WISQARS Non-Fatal Data:
