Injury Data Introduction
Intermediate Injury Prevention
August 23-26, 2011 – Billings, MT
Injury Data Introduction
 Session Goal:
• Review injury data concepts fr: Intro to IP Course
• Understand classification system for injury
morbidity & mortality
 Session Objectives:
• Describe the uses of data
• Define types of data
• Identify common sources of injury data
• Describe classification system for injury coding
• Interpret listings of injury morbidity/mortality codes
In Review…
What are the two types of data?
(hint: words v. numbers)
How are data used in IP?
What are the sources of injury data?
Two Types of Data
Qualitative Data
Interviews
Surveys
Focus groups
Gives insight on
development of your
program/messages/
materials
Quantitative Data
Raw numbers
Counts
Identify injury
patterns
Surveillance
Observations
Risk assessments
Use of Data in Injury Prevention
Understand trends
patterns
Risk factors
Causes of injury in a
population
Set priorities for
prevention
Guide/persuade
decision makers
Develop a program
messaging &
materials (design of
float coats in AK;
safety message for
a targeted group)
Justify needs/build
your case for
funding (i.e., grants)
Evaluate your
program
Common sources of injury data?
Local IHS severe
injury surveillance
system
Resources and
patient management
system
Medical records &
death certificates
EMS & police
Questionnaires
Surveys
Focus groups
Key information
interviews
Observations (seat
belt surveys, home
safety assessments)
In Review…
What are the agents of injury?
(hint: Injury results from the transfer of energy)
What are the two main categories of
injury?
(hint: MVC and Domestic Violence are examples)
Agents of Injury
 Mechanical: crushing
injury in wringer
washer, energy
transferred during MV
crash
 Thermal: heat injuries –
fire, hot water scalding
 Chemical: battery acid
spills, poisoning
 Electrical: lightening
 Radiation: sunburn,
overexposure to x-ray
 Absence of oxygen:
drowning, suffocation,
smoke inhalation,
Carbon monoxide
 Absence of heat:
hypothermia, frostbite
 Excess heat: heat
stroke (hyperthermia)
Two Main Categories of Injury
Unintentional
Drowning
Fall
Fire
Burn
MVC
Poisoning
Intentional
Suicide
