Despite policy efforts to prevent overdose, accidental overdoses among individuals prescribed opioids continue to occur. Guided by Rhodes' Risk Environment Framework, we examined the unintended consequences of restrictive policies by identifying macro policy and micro-level contextual factors that patients prescribed opioids for pain identified as contributing to overdose events.
Semi-structured interviews were conducted with 31 patients prescribed opioids who experienced an accidental opioid overdose between April 2017 and June 2019 in two health systems.
We identified three interrelated factors that emerged within an evolving risk environment and may have increased patients' vulnerability for an accidental opioid overdose: desperation from persistent pain and comorbidities; limited knowledge about opioid medication safety and effectiveness; and restrictive opioid prescribing policies that exacerbated stigma, fear and mistrust and prevented open patient-clinician communication. When experiencing persistent pain, patients took matters into their own hands by taking more medications or in different intervals than prescribed, mixing them with other substances, or using illicitly obtained opioids.
For some patients, macro-level policies and guidelines designed to reduce opioid overdoses by restricting opioid supply may have paradoxically created a micro-level risk environment that contributed to overdose events in a subset of patients.
尽管政策努力旨在防止用药过量,但开处阿片类药物的个体仍会发生意外用药过量。本研究以 Rhodes 的风险环境框架为指导,通过确定患者处方阿片类药物治疗疼痛的宏观政策和微观环境因素,来研究限制政策的意外后果,这些因素被认为导致了用药过量事件。
对 2017 年 4 月至 2019 年 6 月在两个医疗系统中经历意外阿片类药物过量的 31 名开处阿片类药物的患者进行了半结构化访谈。
我们发现了三个相互关联的因素,这些因素出现在不断演变的风险环境中,可能增加了患者意外阿片类药物过量的脆弱性:持续疼痛和合并症带来的绝望;对阿片类药物用药安全性和有效性的认识有限;限制阿片类药物处方的政策加剧了耻辱感、恐惧和不信任,并阻止了开放的医患沟通。当经历持续疼痛时,患者会自行采取措施,服用比规定剂量更多或不同时间间隔的药物、将它们与其他物质混合使用,或使用非法获得的阿片类药物。
对于一些患者来说,旨在通过限制阿片类药物供应来减少阿片类药物过量的宏观政策和准则可能会产生微观风险环境,从而导致一部分患者发生用药过量事件。
