1 Injury Data Introduction Intermediate Injury Prevention August 23-26, 2011 – Billings, MT

2 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

3 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?

4 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

5 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

6 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)

7 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)

8 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)

9 Two Main Categories of Injury Unintentional Drowning Fall Fire Burn MVC Poisoning Intentional Suicide Self-Harm Assault Child Abuse Elder Abuse Domestic Violence

10 International Classification of Disease Diagnosis Codes Cause of Injury Codes ICD-9 (Non-fatal) ICD-10 (Deaths)

11 Diagnosis Codes Morbidity Required for Billing Numeric Updated > annually Phase out: 2013 Mortality Alphanumeric S00-T98 Updated every Oct. Oct. 1, 2013 Morbidity ICD-9 ICD-10

12 Diagnosis Codes - Examples Fractures Open Wound Crushing Burns Poisoning ICD-9ICD-10 Injury to… Head Neck Knee/Lower Leg Mult. Body Parts Burns & Corrosn Frostbite Poisoning S00-S09 S10-S19 S80-S89 T00-T07 T20-T32 T33-T35 T36-T50 See Reference Handout fx vault of skull; closed; no intercranial injury less than 1 hr LOC

13 External Cause of Injury Codes Morbidity Not required for billing Numeric preceded by E E800-E999 Allows for code for Place Updated > annually Phase out: 2013 State laws/coding rates vary IHS hospital d/c rates: high IHS ED & CHS rates: low Mortality Required for death certif Alphanumeric V01-Y98 Allows for code for Place Allows for code for Activity Updated every Oct. Oct. 1, 2013 Morbidity ICD-9 ICD-10

14 Diagnosis Codes - Examples MV Traffic Accidents Falls Suicide/Self-Inflicted Homicide (Assault) E810-E819 E880-E888 E950-E959 E960-E969 ICD-9ICD-10 Transport Accidents Falls Intentional Self-Harm Assault V01-V99 W00-W19 X60-X84 X85-Y09 See Reference Handout

15 Anatomy of an E-Code X X X. Y E Injury CategorySpecificity

16 Anatomy of an E-Code E MVC; collision w/other vehicle Injured person was a motorcyclist

17 Analysis of E-Codes E810.0 E819.1 E813.1 E814.7 E816.0 E819.0 E880.1 E884.0 E884.1 E885.2 E890.1 E890.3 E950.1 E955.0 E965.0 E966.0 MVCE800-E825 FallE880-E888 FireE890-E899 SuicideE950-E959 AssaultE960-E969 MVC invol. pedestrian Fall; playground equip.

18 (E880-E888) Fall from:…escalator…ladder …sidewalk curb…scaffolding …building/structure…diving …well…storm drain/manhole …playground…cliff …chair…wheelchair …bed…other furniture …commode…roller skates …skateboard…skis …snowboard…other/unspecified E-Code Example: Falls

19 Unspecified Fall Fall from sidewalk curb Fall from stairs Fall from chair Fall from commode Analysis of E-Codes E880.1 E880.9 E884.2 E884.6 E888 Falls E800-E888

20 E-Codes Limitations Records Not Always E-coded Miscoding & Inconsistent Coding Poor Chart Info = Nonspecific E-Code Dont Always Provide Desired Specificity Must Stay Apprised of Updates

21 National Center for Health Statistics Injury E Coded on Death Certificate by Coroner State Government E Coded at Hospital County Health Department FatalityHospitalization WISQARS Data System (Web- Based)

22 External Cause of Injury Coding References American Academy of Professional Coders World Health Organization CDC National Center for Health Statistics CDC article on improving E-coding
