项目摘要

There is a nationwide recognition of the public health challenges arising from the incidence and prevalence of chronic pain. In 2017, the National Academies of Sciences published a landmark review of the literature and found conclusive evidence that cannabis can be an effective treatment for chronic pain. To date, 31 states and the District of Columbia have adopted medical cannabis laws (MCLs) legalizing either home cultivation or dispensary-based sales of cannabis for qualifying medical conditions. However, little is known about substitution away from medical treatment of pain when MCLs go into effect, or the impact such substitution has on other health care utilization. The goal of the current study is to examine the association between MCLs and health care utilization for patients with chronic non-cancer pain enrolled in public and private insurance plans. Using the National Institutes of Health 2015 National Pain Strategy as an organizational framework, we will conduct a retrospective, longitudinal, analysis of the difference in prescription medication and pain-related health service utilization in a cohort of patients with chronic pain in states with and without MCLs. In addition, we will conduct sub-analyses for patients living in rural compared to urban areas, and will examine the relationship between MCLs and health care utilization for patients with neuropathic versus nociceptive chronic pain. We will analyze patient-level panel data measured quarterly. Data for this study will come from a sample of privately insured individuals from the Health Care Cost Institute comprehensive claims databases (N ≈ 40 million covered lives; 2015-2019) and two separate samples of publically insured individuals from Medicare (N ≈ 5 million enrollees; 2011-2018) and Medicaid (N ≈ 5 million enrollees; 2011-2017) claims databases. We will employ a series of difference-in- differences regressions estimated separately for each of the insured groups. Our key policy variables will be a measure of any implemented MCL, measures of implemented MCLs by type (dispensary, home-cultivation-only, or THC oils). Individual patient characteristics, county and state demographics, and a series of fixed effects at the state and quarter level will be used as controls in all models. We will also control for policy endogeneity where necessary. Chronic pain and the opioid epidemic are clear public health crises. Preliminary evidence suggests that access to medical cannabis can alter prescription pain medication use. It is thus essential to understand the relationship between MCLs and health care utilization for chronic pain patients in order to optimize public policies and to provide guidance to clinical practitioners on likely patient responses to MCL implementation.

全国范围内都认识到发病率和发病率所带来的公共卫生挑战 2017 年，美国国家科学院发表了一项里程碑式的研究。查阅文献并发现确凿的证据表明大麻可以是一种有效的迄今为止，已有 31 个州和哥伦比亚特区采用了药物治疗慢性疼痛。大麻法 (MCL) 使家庭种植或药房销售大麻合法化然而，对于医疗以外的替代品知之甚少。 MCL 生效时的疼痛治疗，或这种替代对其他健康的影响当前研究的目标是检查 MCL 和护理利用之间的关联。公立和私立医院的慢性非癌性疼痛患者的医疗保健利用情况使用美国国立卫生研究院 2015 年国家疼痛战略作为保险计划。组织框架，我们会进行回顾性的、纵向的、差异性的分析一组患者的处方药和与疼痛相关的卫生服务利用情况有和没有 MCL 的状态下的慢性疼痛此外，我们将对以下情况进行亚分析。与居住在农村地区的患者与城市地区的患者进行比较，并将检查两者之间的关系神经性慢性疼痛与伤害性慢性疼痛患者的 MCL 和医疗保健利用。我们将分析每季度测量的患者水平面板数据。来自医疗保健成本研究所综合的私人参保个人样本索赔数据库（N ≈ 4000 万人；2015-2019 年）和两个单独的样本参加 Medicare 的公共保险个人（N 约 500 万参保者；2011-2018 年）和 Medicaid （N ≈ 500 万注册者；2011-2017 年）我们将采用一系列差异数据库。我们对每个受保群体分别进行了差异回归估计。变量将是任何已实施的 MCL 的度量，按类型实施的 MCL 的度量（药房、家庭种植油或 THC 油）。州人口统计数据以及州和季度层面的一系列固定效应将被用作必要时我们还将控制政策内生性。初步证据表明，阿片类药物的流行是明显的公共卫生危机。获得医用大麻可以改变处方止痛药的使用，因此至关重要。了解 MCL 与慢性疼痛患者医疗保健利用之间的关系为了优化公共政策并为临床医生提供可能的指导患者对 MCL 实施的反应。
