Cohort study on 471 subjects resident in the metropolitan area of Bologna who had visited a public treatment center for problems due to the abuse of cocaine from January 1, 1988 to December 31, 2009. Two user typologies were created: cocaine users (no heroin) and heroin and cocaine users. Crude mortality rates and standardized mortality ratios were calculated. We performed a regression analysis using the Poisson method. The study results show a higher mortality risk for those injecting substances and for subjects who took both heroin and cocaine. They appear to have different characteristics from their counterparts who do not use heroin. Future studies should be oriented to this aspect.
对居住在博洛尼亚大都市区的 471 名曾于 1988 年 1 月 1 日至 2009 年 12 月 31 日期间前往公共治疗中心治疗因滥用可卡因而产生问题的患者进行的队列研究。研究人员创建了两种用户类型：可卡因使用者（无海洛因）和海洛因和可卡因使用者。计算了粗死亡率和标准化死亡率比。我们使用泊松方法进行了回归分析。研究结果表明，注射药物和同时使用海洛因和可卡因的患者的死亡风险更高。他们似乎与不使用海洛因的患者具有不同的特征。未来的研究应该针对这一方面展开。
