Objectives. To characterize cannabis-related disorder medical encounter trends in the US Medicare population during 2017 to 2022. Methods. We conducted a descriptive study, which included 56 624 432 beneficiaries aged 65 years or older and 10 247 953 aged 18 to 64 years with disability. All were continuously enrolled in Medicare (Fee-for-Service or Advantage) for 183 or more days before the first day of the calendar year. We identified cannabis-related disorder encounters using International Classification of Diseases, 10th Revision, Clinical Modification diagnosis codes and computed annual encounter rates per 10 000 beneficiaries. We used the Mann-Kendall test to analyze trends over time. Results. Annual cannabis-related disorder encounter trends among beneficiaries aged 65 years or older ranged from 15.9 (95% confidence interval [CI] = 15.8, 16.0) to 39.3 (95% CI = 39.1, 39.5) per 10 000. Rates among beneficiaries aged 18 to 64 years with disability ranged from 274.8 (95% CI = 273.6, 276.0) to 373.7 (95% CI = 372.3, 375.2) per 10 000. Rates increased over time across both groups, with average annual increases of 4.3 (95% CI = 3.3, 5.3; P = .01) and 17.1 (95% CI = 11.0, 23.2; P = .02) per 10 000, respectively. Conclusions. Further work is needed to explore the impact of coexisting medical conditions on outcomes that result from cannabis-related disorders.

2017-2022 年美国医疗保险受益人中涉及大麻相关疾病的医疗接触趋势。


目标。描述 2017 年至 2022 年期间美国医疗保险人群的大麻相关疾病医疗遭遇趋势。方法。我们进行了一项描述性研究，其中包括 56 624 432 名 65 岁或以上的受益人和 10 247 953 名 18 至 64 岁的残疾受益人。在日历年的第一天之前，所有人都连续参加了 Medicare（按服务收费或优惠）183 天或更长时间。我们使用国际疾病分类、第 10 修订版、临床修改诊断代码确定了与大麻相关的疾病遭遇，并计算了每 10 000 名受益人的年遭遇率。我们使用 Mann-Kendall 检验来分析随时间变化的趋势。结果。65 岁或以上受益人的年度大麻相关疾病遭遇趋势从每 10 000 人 15.9 （95% 置信区间 [CI] = 15.8， 16.0） 到 39.3 （95% CI = 39.1， 39.5） 不等。18 至 64 岁残疾受益人的发病率为每 10 000 人 274.8 例（95% CI = 273.6、276.0）至 373.7 例（95% CI = 372.3、375.2）。两组的发病率均随着时间的推移而增加，平均年增长率为 4.3 （95% CI = 3.3， 5.3;P = .01） 和 17.1 （95% CI = 11.0， 23.2;P = .02） 的 10 000 例。结论。需要进一步的工作来探索共存的医疗条件对大麻相关疾病结果的影响。（美国公共卫生杂志，2024 年;114（S8）：S694-S697。https://doi.org/10.2105/AJPH.2024.307729）。
