  1. Linking Dispatch, Paramedic,Hospital, and Regional Planning Data in Portland, Oregon: Geospatial Analysis of Traffic-Related Injury Data Christopher Bangs, MS Department of Emergency Medicine, Oregon Health & Science University Portland, Oregon

  2. The Annual Toll of Traffic-RelatedInjury in the USA and Oregon • On an average, each year in the USA • Millions are injured in motor vehicle crashes. • 42,000 persons die. • On an average, each year in Oregon • There are 5,000+ hospitalizations for motor vehicle trauma. • 400-500 persons die. (sources: NHTSA, NSC, CDC, ODOT, Oregon EMS, Oregon Trauma Registry)

  3. Scope of the project: • We propose to link non-traditional data sources with traffic-related injury data to provide an improved understanding of the causes, consequences, and social implications of injury as a public health problem in the Portland, Oregon metropolitan region. • We developed a geocoded dataset to link these datasets, and provide a foundation for spatial analysis.

  4. Primary Data Source (TCC): Area Trauma communications center - regional trauma system data • TCC staff verify injury incident location by contacting either paramedic or Bureau of Emergency Communications during the same shift, and are trained in geocoding methods. • Geocoding began on April 1, 1995. • Address match rate = ~95% with manual correction, using the Oregon Trauma Band Number (placed on patient in the field).

  5. Primary Data Source (METRO RLIS): Metropolitan regional land use information systems data • Metro regional government is a directly-elected regional authority serving the Portland tri-county region. • Similar to metropolitan planning organization. • Maps include street networks, county, flood plain maps, traffic analysis zones, planning zones, and USGS topographic maps, geocoded and current for the region.

  6. Other Data Sources • Multnomah County EMS trauma data (subset of Oregon Trauma Registry) • Portland police neighborhood crime data [CRIME] • Oregon and OHSU Trauma Registries • Hospital emergency department information system

  7. Retrospective, population & incidence studies with spatiotemporal analyses OHSU houses the TCC data repository. TCC staff require the assignment of trauma band number by the prehospital provider if they are missing or duplicated by first responders in the field. Methods

  8. Trauma Communications Record Neighborhood Crime Data Trauma Band Number Pre-Hospital Chart EDIS / Hospital Charts 911 Dispatch Data OTR

  9. Map 1 Area of Study: Portland, Oregon metropolitan area Regional Trauma System

  10. Map 2 Findings: All Traumas (1995-1999)

  11. Map 3

  12. Limitations of Linking Datasets • Common trauma registry limitations - missing data, retrospective data, addresses are incomplete/incorrect. • Descriptive maps based upon both points and aggregations. • Crime data were incomplete, so sampling was required. • Agencies use different operational and field definitions for data points and variables.

  13. The Oregon trauma band number links disparate datasets METRO RLIS neighborhood base maps EMS data repository for dispatch, trauma, cardiac and hospital outcome data Census, police, planning, and other Oregon agency databases are embracing GIScience OHSU houses national ED electronic surveillance projects (CDC EMERGE ID NET) Strengths and Unique Considerations

  14. Linking medical databases for optimal patient care and population studies – potentialities • “The Australian government…is creating a Master Person Index to allow its socialized health care system to identify and access the medical records of any citizen brought to a hospital for treatment. This is not a single monolithic database but rather the creation of an index that involves linking and integrating the many hospital-patient databases…” • Ephraim Schwartz in INFOWorld Sept. 24, 2001

  15. Conclusions • Accurate and precise base maps are critical. • Creation of a common link in the identifier dataset is critical to linking both traditional and non-traditional databases. • Spatial data do not correlate with medical outcome data; a linking mechanism is required. • Disparate datasets can communicate and enhance our understanding of the injury problem. • Collaboration among organizations provides opportunity to expand knowledge and extend resources to study public health issues.

  16. Spatiotemporal variations in traffic injury Spatiotemporial aspects of EMS services, based on trauma activity Proximity of injury to destinations, types of businesses, parks, etc. Oregon trauma band number utilization and outcome data EMS injury surveillance system, linking traffic injury, SES, planning, social and crime data Research is Promising: The Now and Future www.ohsu.edu/som-EmergMed - www.ohd.hr.state.or.us/ems www.portlandpolicebureau.com - www.metro-region.org
