Local Data on Injury Hospitalizations

Data from Hospital Billing Departments • Based on the 2004 Universal Billing form (UB-04) • May be available for both ED visits and hospital discharges • Includes basic information on: ─ ─ ─ Patient demographics (e. g. , age, sex) Diagnoses Cause of injury Procedures Hospital charges

Data from Hospital Billing Departments • Diagnoses, causes of injury and procedures are coded using the ICD-9 -CM ─ Change to ICD-10 -CM in October 2014 • Tools for creating standard groups ─ Barell Matrix, for injury diagnoses injuryprevention. bmj. com/content/8/2/91. full. pdf+html ─ ICD-9 -CM External Cause Matrix, for causes of injury www. cdc. gov/injury/wisqars/ecode_matrix. html

National Data on Injury Hospitalizations

Web-based Injury and Statistics Query and Reporting System (WISQARS) Centers for Disease Control and Prevention • Data are obtained from a sample of hospital emergency departments and analyzed to provide national estimates • Includes ED visits and hospitalizations that result from ED visits • On-line query system www. cdc. gov/injury/wisqars/index. html

5 Leading Causes of Non-fatal Injury for Children Treated and Released from the ED By Age Group, US, 2011 Rank <1 1 -4 5 -9 10 -14 15 -19 1 Fall Struck by/ Against* 2 Struck by/ Against* Fall 3 Other bite/sting+ Overexertion 4 Foreign body Cut/pierce MV Occupant 5 Fire/burn Overexertion Pedal cyclist Physical Assault *Accidentally struck by or struck against a person or object, including in sports +Bite or sting, not including dog bites

Healthcare Cost and Utilization Project (HCUP) Agency for Healthcare Research and Quality • Hospital discharge data from 44 states • Can provide national estimates on injury hospitalizations and ED visits • Several on-line query systems, one specific to kids Pediatric age groups are pre-set ─ Need to have an understanding about ICD codes ─ hcupnet. ahrq. gov ─

Percent of Children Ages < 17 with Traumatic Brain Injury (TBI) admitted to the hospital from the ED 12% 10% 8% 6% 4% Age < 1 Ages 1 -17 2% 0% 2006 2007 2008 2009 ICD-9 -CM codes for TBI: 800 -804, 850 -854, 950. 1 -950. 3, 995. 55, 959. 01 From the National Emergency Department Sample (NEDS), HCUPnet at http: //hcupnet. ahrq. gov/ 2010

Suggestions for Getting Started • Identify people who can help • Learn a little bit about the International Classification of Diseases (ICD) codes for injury • On-line tools for national estimates

Injury Surveillance In Connecticut

Data in Connecticut • What we have • How we share it • What we can do with it

Our set up • Safe Kids Connecticut is a program of the Injury Prevention Center (IPC) • IPC has 10 hour per week GIS Research Assistant (RA) to run geo -spatial analysis (including making maps) and run data • Money for RA and to purchase data comes out of IPC money

Our statewide resources • Dept of Public Health (DPH) – No longer has Injury Prevention section • Lost funding 2011 • Previously had injury data and ran CODES project • Dept of Transportation (DOT) – Has some data, but MV only • Poison Control Center – Has some data, but Poison only

Statewide Resources (cont’d) • Office of the Child Advocate – Runs Connecticut Child Fatality Review Panel which reviews all unexpected and unexplained child deaths – Runs special analysis upon request – Detailed information on topics like safe sleep – We do not have access to the data but do to the detailed analysis

Data we have – Purchased • Connecticut Hospital Association (CHA) – Emergency Department visits – Hospitalizations – Deaths (that occur in a hospital or are processed through a hospital) • DPH - Vital Records – CT Death Certificate Files – $10/year

Data we have - Free • DOT Crash file – Requires extensive formatting and processing of the data • Medical Examiner Data – Must request yearly – Specific Causes (Firearm and Drowning)

Data Limitations • Data Cleaning – Almost all data we receive (including CHA) requires extensive data formatting processing • Time Lag – We generally have a 2 to 3 year data lag • Example: Just now requesting 2011 and 2012 data • Hard to compare long periods of time – Ex) CT Death cert data 1990 -2010, but change in ICD 9 to ICD 10 makes long term analysis difficult

Data Limitations • E-Codes make certain information hard to get – Motor vehicle crash info? Yes! – Bike crash info? No… (only if they crashed into MV) • Based on cause of injury, rather than consumer product – Bikes – Batteries – Crib bumpers

Sharing data • Due to our agreements, we share the analysis of the data, not the raw data • We share data via: – ED Injury books for our local Safe Kids – Reports (Drowning, violent death) – Requests

ED data books • Updated when we get new data from CHA • Data books started 1995 and ends 2010 • We give all unintentional injury data for kids 19 and under by 5 year age groups • Data broken down by county (8) and then total for the state • We collapse and expand categories as needed • Given to each local Safe Kids organization

Safe Kids in CT are not county based

Example from Data Book

How we use our data • Media – Lots of requests for local data • Especially with national reports • Stories we pitch to them – Posts for our Facebook page – Social media for our lead organization

How we use our data • Grants – Statewide data – Local data for local foundations – Mapped data – Safe Kids Worldwide

Using E-Coded Data in the Pediatric Emergency Department Rennie Ferguson, MHS, CPH Safe Kids Worldwide CHILDHOOD INJURY PREVENTION CONFERENCE 2013 36

Objectives • • Purpose of E-coding Why it isn’t used more often Hospital-based injury surveillance Components of a successful injury surveillance system CHILDHOOD INJURY PREVENTION CONFERENCE 2013 37

Pediatric Emergency Care, July 2013 CHILDHOOD INJURY PREVENTION CONFERENCE 2013 38

Injury surveillance systems • Provide information on populations susceptible to injury, types of injuries, and factors that put people at increased risk • How well interventions are working • Successful systems require: • • Simplicity Flexibility Acceptability Reliability Utility Sustainability Timeliness CHILDHOOD INJURY PREVENTION CONFERENCE 2013 39

What is E-coding? • International Classification of Diseases external causes of injury and poisoning codes • Provide information about mechanism, location and intentionality of the injury CHILDHOOD INJURY PREVENTION CONFERENCE 2013 40

Design of literature review • 2 sets of search criteria: • E-coding in the PED • Injury surveillance by the PED • Pub. Med, Pub. Med Central, Google Scholar • CINAHL, EMBASE, Academic Search Elite • Exclusion criteria CHILDHOOD INJURY PREVENTION CONFERENCE 2013 41

Findings • 111 sources identified • E-coding in the PED: 2 reports met criteria • Non-E-coding PED injury surveillance: 5 reports met criteria CHILDHOOD INJURY PREVENTION CONFERENCE 2013 42

Injury surveillance in PED CHILDHOOD INJURY PREVENTION CONFERENCE 2013 45

Common challenges • Insufficient chart information (n=4) • Incompleteness of questionnaires by physicians (n=2) • Bias toward more severe cases (n=1) CHILDHOOD INJURY PREVENTION CONFERENCE 2013 46

Reduce the burden • Earlier systems: “flagging” injury cases, questionnaires, assigning clinical staff to enter data • Economic and resource burden • Electronic charting CHILDHOOD INJURY PREVENTION CONFERENCE 2013 47

Practicality • Usefulness in tracking health outcome of interest • Falls (n=2) • Relevant by tailoring questions • Ease of use for hospital trauma education coordinators and others CHILDHOOD INJURY PREVENTION CONFERENCE 2013 48

Ensuring data quality • Little published research on quantifying the accuracy of E-codes • Outside of PED—ranged from 64 -85% (Mc. Kenzie 2009) • Need for more research on feasibility, quality, and utility of individual hospital PED injury surveillance systems • Role of triage nurses, parents in improved Ecoding CHILDHOOD INJURY PREVENTION CONFERENCE 2013 49
