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
