Methadone-related overdose deaths increased in the United States by 468% from 1999 to 2005. Current studies associate the nonmedical use of methadone with methadone-related deaths. This study describes medical examiner cases in rural Virginia in 2004 with methadone identified by toxicology and compares cases according to source of methadone.
In 2004, all intentional and unintentional poisoning deaths from the Office of The Chief Medical Examiner, Western District of Virginia, were reviewed to identify cases in which methadone was a direct or contributing cause of death. The Virginia Prescription Monitoring Program was reviewed for prescription opioids in the name of these identified decedents. Decedent participation in local opioid treatment programs (OTP) was also assessed.
The source of methadone in the 61 methadone-related overdose deaths was mostly nonprescribed (67%), although 28% of decedents were prescribed methadone for analgesia. Only 5% of decedents were actively enrolled in an OTP. The majority of deaths were attributed to polysubstance overdose.
The majority of methadone overdose deaths in this study were related to illicit methadone use, rather than prescribed or OTP uses. Interventions to decrease methadone-related deaths should focus on reduction of nonprescription use of methadone.
1999 年至 2005 年,美国与美沙酮相关的过量死亡人数增加了 468%。目前的研究将美沙酮的非医疗用途与美沙酮相关的死亡联系起来。本研究描述了 2004 年弗吉尼亚州西部法医办公室的案例,这些案例中的美沙酮通过毒理学鉴定,并根据美沙酮的来源对案例进行了比较。
2004 年,审查了来自弗吉尼亚州西部首席法医办公室的所有故意和非故意中毒死亡案件,以确定美沙酮是直接或间接导致死亡的原因。审查了弗吉尼亚州处方监测计划,以确定这些确定死者的名字中有哪些处方类阿片。还评估了死者在当地阿片类药物治疗计划(OTP)中的参与情况。
61 例与美沙酮相关的过量用药死亡案例中,美沙酮的来源主要是非处方(67%),尽管 28%的死者因镇痛而开了美沙酮。只有 5%的死者积极参加 OTP。大多数死亡归因于多种物质过量。
本研究中大多数美沙酮过量死亡与非法美沙酮使用有关,而不是处方或 OTP 使用。减少与美沙酮相关的死亡的干预措施应侧重于减少美沙酮的非处方使用。
