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 Self-Harm Assault Child Abuse Elder Abuse Domestic Violence
