Abstract |
OBJECTIVE: The research objective is to compare the consistency of distributions between crash assigned (KABCO) and hospital assigned (AIS) injury severity scoring systems for two states. The hypothesis is that AIS scores will be more consistent between the two studied states (Maryland and Utah) than KABCO. METHODS: The analysis involved CODES data from two states, Maryland and Utah for years 2006 - 2008. Crash report and hospital inpatient data were linked probabilistically and ICD-9-CM codes from hospital records were translated into AIS codes. KABCO scores from police crash reports were compared to those AIS scores within and between the two study states. RESULTS: Maryland appears to have the more severe crash report KABCO scoring for injured crash participants with close to 50% of all injured persons being coded as a level B or worse, while Utah observes approximately 40% in this group. When analyzing AIS scores, some fluctuation is seen within states over time, but the distribution of MAIS is much more comparable between states. Maryland had approximately 85% of hospitalized injured cases coded as MAIS = 1 or minor. In Utah this percentage is close to 80% for all three years. This is quite different from the KABCO distributions, where Maryland had a smaller percentage of cases in the lowest injury severity category as compared to Utah. CONCLUSIONS: This analysis examines the distribution of two injury severity metrics different in both design and collection and found that both classifications are consistent within each state from 2006-2008. However, the distribution of both KABCO and MAIS varies between the states. MAIS was found to be more consistent between states than KABCO. Language: en |
