| Summary: | 博士 === 國立中央大學 === 機械工程研究所 === 96 === Lower death rate and longer life years are two objectives of medicine science. According the estimates published by World Health Organization, the deaths caused by injuries would increase 40% from year 2020 to 2030. Most of them were crash fatalities. By then, the crash would rank 4-5 in the causes of deaths.
The present study linked the heterogeneous police reported crash data with vital registration data to build an integrated database. Then, two common used fatality indexes, 30 days fatality adjustment factors under different fatality time definition and years of life lost (YLL), were used to investigate the influence of various risk factors on crashes. The results were also compared with international data.
The major results were: 1) Taiwan’s adjustment factor at the first day of crash was higher than that in Europe and Japan. It indicated more late deaths in Taiwan. 2) Illustrated by fatality adjustment factors, thorax injuries were the most exigent factor among the investigated risk factors. 3) The YLL rates of the youth were highest across age groups. However, the YLL rates of the elder were visible high, and higher than that in Western Pacific Region B area. 4) The factors on YLL rate rank various among sex and age groups; however, head injuries, injuries involving urban roads and dry road condition were the factors with higher YLL rate in all groups. 5) Different fatality indexes could provide various crashes features.
Integrating heterogeneous data could efficiently combine existing databases to provide valuable information. The experiences in present study demonstrated that it could compare local data with international data and investigate advanced.
