Table 1_Driver, vehicle, and environmental risk factors for crash-level major trauma in drunk driving collisions: a national registry linkage study.docx

However, there is a lack of evidence regarding the driver-related, vehicle-related and environmental risk factors for major trauma in drunk driving crashes.</p>Methods<p>We retrospectively analyzed crash-level data from the National Health Insurance Research Database (NHIRD) and Traffic Accident Data (TAD) from 2012 to 2019.

Data from all the drunk-driving violations from this period were extracted, and we categorized these violations based on whether they resulted in major trauma to any involved party (including drivers, passengers, and pedestrians). Due to the lack of fault-attribution in the TAD, detailed person-level data was not included in the analysis. The risk factors for major trauma in drunk-driving traffic crashes (i.e., driver-related factors, vehicle-related factors, and environmental factors) were identified via multivariable logistic regression.</p>Results<p>We retrieved data from 96,860 drunk-driving traffic crashes during the study period.
