Background: Although alcohol-intoxicated patients have difficulties evaluating their consciousness level and being transported prehospital, there is some evidence that the survival outcomes for alcohol-intoxicated patients with head injuries are better. The present study evaluated whether the survival and brain function outcomes in alcohol-intoxicated trauma patients with head injuries were better than those in sober patients using the Japan Trauma Data Bank (JTDB), a nationwide trauma registry in Japan., Methods: The 17,823 patients with blunt trauma, including head injuries, who were registered in the JTDB database between January 2019 and December 2021 were retrospectively analyzed. Logistic regression analyses were performed for in-hospital survival in patients with blunt trauma, including those with head injuries, and for good brain function based on the Glasgow outcome scale (GOS) in patients with only head injuries. Survival rates by head injury score using the abbreviated injury scale (AIS) 2008 or injury severity score (ISS) categories were compared between drinking and nondrinking groups., Results: Drinking significantly affected survival (odds ratio 1.800, p<0.001) and good brain function (odds ratio 1.546, p<0.001), as indicated by logistic regression analysis using head injuries alone or blunt multisite trauma (including head injuries), respectively. According to analyses by the ISS category or head AIS score, there were significant differences between the drinking and non-drinking groups in several categories (ISS 9-15, 16-24, and 25-40 and AIS 3 and 5) regarding survival rates with blunt trauma, including head injuries, or good GOS rates with head injuries alone., Conclusions: The survival rates for blunt trauma, including head injuries, and the prognosis for brain function based on the GOS were better in the drinking group than in the control group for cases with head injuries alone. A multivariate analysis also showed that alcohol consumption was significantly associated with better outcomes., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Introduction: The characteristics of ski- and snowboard-related fatalities at Japanese ski resorts remain unknown. We aimed to analyze the characteristics of this in the current study., Methods: Using the Ski Resort Injury Report data for the 13-y period between the 2011-12 and 2022-23 seasons, we described the characteristics of fatal accidents due to exogenous causes., Results: Eighty-four subjects (48 skiers and 36 snowboarders) were analyzed. Males accounted for 73 cases of all 84 fatalities (86.9%), including 44 skiers (91.7%) and 29 snowboarders (80.6%). Skiers aged ≥50 y and snowboarders aged 20-35 y had the highest number of fatal accidents (32 and 18 cases, respectively). Regarding location, 26 fatal accidents occurred on slopes, and 58 occurred out of slopes (skiers, 11 and 37 cases; snowboarders, 15 and 21 cases, respectively). Among skiers, head and neck trauma accounted for the cause of death in 13 cases (27.1%) and asphyxiation in 11 cases (22.9%). Among snowboarders, head and neck trauma accounted for the cause of death in 14 cases (38.9%) and asphyxiation in 14 cases (38.9%)., Conclusions: Males, particularly those aged ≥50 among skiers and 20-35 among snowboarders, should be wary of the potential for injuries to the head, neck, and airway when skiing or snowboarding. In this study, traumatic deaths from crashing into trees and asphyxiation from deep snow immersion accidents accounted for approximately half of fatal ski accidents in Japan.
