Following the 2016 opioid overdose emergency declaration in British Columbia (B.C.), provincial stakeholders collaborated to link data that resulted in the B.C. Provincial Overdose Cohort. This database provides information about people who have experienced opioid overdoses to inform policy and intervention developments. Subsequently, Statistics Canada likewise constructed a cohort and integrated federal data to broaden the scope of the B.C. initiative. This provided federally sourced information about people's circumstances that was not otherwise available.
The Statistics Canada British Columbia Opioid Overdose Analytical File further characterizes the socioeconomic circumstances of 13,318 people who experienced illicit drug toxicity deaths and non-fatal opioid overdoses in B.C. between January 1, 2014, and December 31, 2016. Statistics Canada linked federal data on immigration, employment, the justice system and social assistance receipt in the year of, and prior to, people's first overdose.
During the observation period, most people (78%) had one overdose episode, rather than several. Seven percent were immigrants or temporary residents, 41% of whom arrived in Canada more than 20 years before their index overdose. Half (49.6%) had not received social assistance, and one-third (33.8%) were employed-primarily within construction (21% of those employed)-in the year prior to their index overdose. Most employed people (65.5%) experienced periods of unemployment within five years prior to their index overdose. Employment was more prevalent among people who experienced illicit-drug toxicity death (36.1%). About 60% of people had not had any formal police contact within the two years prior to the index overdose.
This project demonstrated further added value to existing data by using this linkage approach and aligned with strategies underway by BC public health partners to provide cross-sectoral evidence to inform efforts to prevent and manage opioid overdoses.
2016 年不列颠哥伦比亚省（BC 省）宣布出现阿片类药物过量紧急情况后，省级利益相关者合作建立了一个数据库，将数据链接起来，形成了 BC 省药物过量队列。该数据库提供了有关经历阿片类药物过量的人群的信息，以支持政策和干预措施的制定。随后，加拿大统计局也构建了一个队列，并整合了联邦数据，扩大了 BC 倡议的范围。这提供了联邦来源的关于人们情况的信息，否则这些信息是无法获得的。
加拿大统计局不列颠哥伦比亚省阿片类药物过量分析文件进一步描述了 2014 年 1 月 1 日至 2016 年 12 月 31 日期间在 BC 省经历非法药物毒性死亡和非致命阿片类药物过量的 13318 人的社会经济情况。加拿大统计局将联邦数据链接到移民、就业、司法系统和社会援助领取情况，这些数据是在人们第一次过量用药的当年及其前一年收集的。
在观察期内，大多数人（78%）经历了一次过量用药事件，而不是多次。7%是移民或临时居民，其中 41%在他们的索引过量用药前 20 多年抵达加拿大。一半（49.6%）没有领取社会援助，三分之一（33.8%）在索引过量用药前一年就业-主要在建筑行业（就业人口的 21%）。大多数就业人员（65.5%）在索引过量用药前五年内经历了失业期。在经历非法药物毒性死亡的人群中，就业情况更为普遍（36.1%）。约 60%的人在索引过量用药前两年内没有与警方有任何正式接触。
通过使用这种链接方法，该项目展示了现有数据的进一步增值，并与 BC 省公共卫生合作伙伴正在进行的战略保持一致，以提供跨部门证据，为预防和管理阿片类药物过量提供信息。
