Impact of speed cameras on trauma centers

In 2008, speed cameras were implemented in the state of Arizona, with the goal of reducing motor vehicle collisions and associated injury severity. Due to continued opposition, the cameras were removed in 2010. The focus of this study is the impact of speed cameras on Level 1 trauma center (L1TC) admissions. The authors hypothesize that speed cameras reduce L1TC admissions and that they reduce kinetic energy, thus lowering injury severity score (ISS), mortality, hospital costs and length of stay. Using collision data from the Arizona Department of Transportation and the Arizona State Trauma Registry for 2009-2011, a retrospective review is conducted of patients admitted to L1TCs after being injured along a 26-mile stretch of I-10 in Phoenix. Data is collected for a period in 2009 when cameras were in place and a period in 2011 when no cameras were in place. Among their findings are a twofold increase in L1TC admissions and increased resource use associated with speed camera removal. The findings show no significant difference between the two time frames for ISS, mortality, median charges, or median length of stay.
