In recent years, North America has witnessed a spike in the number of overdoses (OD) and OD-related deaths. The aim of this study was to assess spatial correlates of OD risk in Vancouver, Canada.
Data utilized for this study was from three open and ongoing prospective cohorts of people who use drugs (PWUDs) in Vancouver, Canada. Logistic regression analyses with generalized linear mixed-effects models (GLMM) was used to examine correlates of residing in areas characterized by high OD rates. Mapping was used to examine areas showing OD clusters.
We included 1336 PWUDs who resided in the downtown area. In multivariable analysis, higher availability of methadone clinics within walking distance, daily cocaine injectors and daily crack users had independent decreased odds of living within an OD cluster.
This study found that higher availability of methadone clinics was associated with decreased odds of living within OD clusters.
近年来，北美地区药物过量（OD）及与OD相关的死亡人数激增。本研究旨在评估加拿大温哥华药物过量风险的空间关联因素。
本研究使用的数据来自加拿大温哥华三个正在进行的开放前瞻性吸毒人群（PWUDs）队列。采用广义线性混合效应模型（GLMM）进行逻辑回归分析，以检验居住在药物过量率高的地区的相关因素。通过绘图来检查显示药物过量聚集的区域。
我们纳入了1336名居住在市中心地区的吸毒人群。在多变量分析中，步行距离内美沙酮诊所数量较多、每日注射可卡因者和每日吸食快克者居住在药物过量聚集区的几率独立降低。
本研究发现，美沙酮诊所数量较多与居住在药物过量聚集区的几率降低有关。
