  1. MAGIC BEHIND MOTOR VEHICLE CRASH FATALITY TRENDSA closer look at Nebraska crash data Ying Zhang, PhD. Ashley Newmyer, MPH Jihyun Ma, MS Ming Qu, PhD.

  2. Background • Gov. Dave Heineman applauded the safe actions of motorists who contributed to one of the lowest traffic fatality totals on record for the state. The fatality total for 2010 was 186 (updated 190), the second lowest total since recordkeeping began 73 years ago. (www.governor.nebraska.gov, January 1, 2011)

  3. Background • In 2010, about 32,800 people lost their lives due to motor vehicle crashes on the nation’s roads. • The 3 percent decrease from 2009 brings the number of road deaths to the lowest level since the federal government began keeping records in 1949. • Decades of public health interventions aimed at preventing deaths on the nation’s roads are making a difference.

  4. In this study… • To explore factors that possibly contributed to crash fatality decrease Method • Nebraska CODES data including Crash (2000-2010), hospital discharge data (2002-2008) • Trauma registry data (2001-2010) • EMS data (2005-2009) • Variables • Person: age, gender, • Risk factor: alcohol, seat belt • Crash: type, location, time • Trauma care • EMS response

  20. Summary • The following factors may have contributed to the decline of crash fatality • Increasing seatbelt usage • Alcohol related crash fatality • Improved trauma care • Faster EMS response, especially at rural areas
