Abstract

Introduction: In Canada, alcohol-impaired driving is a persistent public health concern in need of effective community-based prevention strategies. This study examined the association between the number of rides offered by a safe-ride program in the province of Quebec every December and alcohol-related injury crashes during the 2000-2019 period.

Method: Safe-ride programs in four cities were examined (Montreal, Quebec, Sherbrooke and Trois-Rivières) using an ecological approach. The data set was structured as a balanced cross-sectional time series. Random-effects negative binomial regression modelled the relationship between the number of rides provided by the safe-ride program and night-time alcohol-related crashes involving serious injuries and fatalities, with individual city population as an offset variable.

Results: The median number of night-time alcohol-related crashes for the months of December for the 2000-2019 period was 3.0 (IQR=1.5-4.5). The median number of rides offered was 16 894 (IQR=15 586-18 391). The association between the number of rides provided by the safe-ride program and night-time alcohol-related crashes (IRR=1.0002; 95% CI 0.9999, 1.0005) was not significant.

Conclusion: The role of the number of rides provided by the safe-ride program in reducing night-time alcohol-related crashes was inconclusive. Specific program features may influence the findings. Future research is needed to understand the specific characteristics of safe-ride programs that could influence their putative benefits.

导言：在加拿大，酒后驾驶是一个长期存在的公共健康问题，需要有效的社区预防策略。本研究考察了 2000-2019 年间魁北克省安全乘车计划每年 12 月提供的乘车次数与酒精相关伤害事故之间的关联：采用生态学方法研究了四个城市（蒙特利尔、魁北克、舍布鲁克和三河市）的安全乘车计划。数据集的结构为平衡横截面时间序列。随机效应负二项回归模拟了安全乘车计划提供的乘车次数与夜间涉及严重伤亡的酒精相关碰撞事故之间的关系，并将单个城市人口作为抵消变量：2000 年至 2019 年 12 月期间，夜间与酒精相关的车祸中位数为 3.0（IQR=1.5-4.5）。提供的乘车次数中位数为 16 894 次（IQR=15 586-18 391）。安全乘车计划提供的乘车次数与夜间与酒精相关的车祸之间的关系（IRR=1.0002；95% CI 0.9999，1.0005）并不显著：结论：安全乘车计划提供的乘车次数在减少夜间酒精相关撞车事故方面的作用尚无定论。具体的项目特点可能会影响研究结果。未来的研究需要了解安全乘车计划的具体特点，这些特点可能会影响其假定的益处。

期刊介绍： Since its inception in 1995, Injury Prevention has been the pre-eminent repository of original research and compelling commentary relevant to this increasingly important field. An international peer reviewed journal, it offers the best in science, policy, and public health practice to reduce the burden of injury in all age groups around the world. The journal publishes original research, opinion, debate and special features on the prevention of unintentional, occupational and intentional (violence-related) injuries. Injury Prevention is online only.
