High blood alcohol concentration associated with traumatic brain injury among traffic injury patients during New Year festivals in Thailand

Objective: Road traffic injury (RTI) is one of the most significant public health problems in Thailand, especially during New Year and Songkran (Thai traditional New Year) holidays, which have the highest traffic density during the entire year. Drunk driving was reported to be one of the leading causes of RTI in Thailand. This study aimed to investigate the prevalence of patients with high blood alcohol concentration (BAC) and the association of BAC and specific organ injury during New Year and Songkran (Thai traditional New Year) holidays.

Methods: A cross-sectional study was performed to analyze the database from the Thai Governmental Road Safety Evaluation Project. Patient data on RTIs were collected from 26 main provincial hospitals during the New Year Festival 2003 and 2004 and Songkran Festival in 2003. Patient characteristics, type of organ injured, and BAC levels were mainly analyzed.

Results: During those long holidays, 2,642 RTI patients were identified, among whom 1,341 patients had high BAC levels. High BAC levels were associated with motorcycle users, male sex, middle age, teenagers, being riders or drivers, and not using protective devices. Moreover, high BAC levels were associated with brain injury.

Conclusion: Excessive alcohol consumption and RTIs occurred on New Year and Songkran Festival in Thailand. Legislation should be strictly used during these long holidays to control driving under the influence of alcohol, particularly among motorcyclists.
