Background:Physicians’ professional networks are an important source of new medical information and have been shown to influence the adoption of new treatments, but it is unknown how physician networks impact the de-adoption of harmful practices.Methods:We analyzed changes in physicians’ use of dronedarone after the PALLAS trial (Palbociclib Collaborative Adjuvant Study; November 2011) showed that dronedarone increased the risk of death from cardiovascular events among patients with permanent atrial fibrillation. Deidentified administrative claims from the OptumLabs Data Warehouse were combined with physicians’ demographic information from the Doximity database and publicly available data on physicians’ patient-sharing relationships compiled by the Centers for Medicare and Medicaid Services. We used a linear probability model with an interrupted linear time trend specification to model the impact of the PALLAS trial on physicians’ dronedarone usage between 2009 and 2014.Results:Before the PALLAS trial, the use of dronedarone was increasing by 0.22 percentage points per quarter (95% CI, 0.19–0.25) in our Medicare Advantage sample (N=343 429 patient-quarter observations) and 0.63 percentage points per quarter (95% CI, 0.52–0.75) in our commercially insured sample (N=44 402 patient-quarter observations). After the PALLAS trial and subsequent United States Food and Drug Administration black box warning, physicians in the Medicare Advantage sample with an above-median number of network connections to other physicians decreased their quarterly usage of dronedarone by 0.12 percentage points more per quarter (95% CI, −0.20 to −0.04; P=0.031) than physicians with equal to or below the median number of network connections. Similar patterns existed in the commercially insured sample (P=0.0318).Conclusions:After controlling for a wide range of patient, physician, and geographic characteristics, physicians with a greater number of network connections were faster de-adopters of dronedarone for patients with permanent atrial fibrillation after the PALLAS trial and subsequent United States Food and Drug Administration black box warning detailed the harmfulness of dronedarone for these patients. Policies for improving physicians’ responsiveness to new medical information should consider utilizing the influence of these important professional network relationships.

医生网络连接与更快地停用决奈达隆治疗永久性心房颤动有关

背景:医生的专业网络是新医学信息的重要来源,已被证明会影响新疗法的采用,但尚不清楚医生网络如何影响有害做法的取消。方法:我们分析了医生的变化PALLAS 试验后使用决奈达隆(Palbociclib 协作辅助研究;2011 年 11 月)表明决奈达隆增加了永久性心房颤动患者死于心血管事件的风险。来自 OptumLabs 数据仓库的未识别行政声明与来自 Doximity 数据库的医生人口统计信息以及由医疗保险和医疗补助服务中心汇编的关于医生患者共享关系的公开数据相结合。我们使用具有中断线性时间趋势规范的线性概率模型来模拟 PALLAS 试验对 2009 年至 2014 年间医生决奈达隆使用的影响。结果:在 PALLAS 试验之前,决奈达隆的使用每季度增加 0.22 个百分点(95% CI, 0.19–0.25) 在我们的 Medicare Advantage 样本(N=343 429 患者季度观察)和我们的商业保险样本(N=44 402 患者)中每季度 0.63 个百分点(95% CI,0.52–0.75) -季度观察)。在 PALLAS 试验和随后的美国食品和药物管理局黑框警告之后,Medicare Advantage 样本中与其他医生的网络连接数量高于中位数的医生每季度将决奈达隆的季度使用量减少了 0.12 个百分点(95% CI,-0.20 至 -0.04;在 PALLAS 试验之前,在我们的 Medicare Advantage 样本(N=343 429 患者季度观察)中决奈达隆的使用每季度增加 0.22 个百分点(95% CI,0.19–0.25),每季度增加 0.63 个百分点(95% CI,0.52–0.75)在我们的商业保险样本(N=44 402 患者季度观察)中。在 PALLAS 试验和随后的美国食品和药物管理局黑框警告之后,Medicare Advantage 样本中与其他医生的网络连接数量高于中位数的医生每季度将决奈达隆的季度使用量减少了 0.12 个百分点(95% CI,-0.20 至 -0.04;在 PALLAS 试验之前,在我们的 Medicare Advantage 样本(N=343 429 患者季度观察)中决奈达隆的使用每季度增加 0.22 个百分点(95% CI,0.19–0.25),每季度增加 0.63 个百分点(95% CI,0.52–0.75)在我们的商业保险样本(N=44 402 患者季度观察)中。在 PALLAS 试验和随后的美国食品和药物管理局黑框警告之后,Medicare Advantage 样本中与其他医生的网络连接数量高于中位数的医生每季度将决奈达隆的季度使用量减少了 0.12 个百分点(95% CI,-0.20 至 -0.04;在我们的商业保险样本(N=44 402 患者季度观察)中,每季度 63 个百分点(95% CI,0.52-0.75)。在 PALLAS 试验和随后的美国食品和药物管理局黑框警告之后,Medicare Advantage 样本中与其他医生的网络连接数量高于中位数的医生每季度将决奈达隆的季度使用量减少了 0.12 个百分点(95% CI,-0.20 至 -0.04;在我们的商业保险样本(N=44 402 患者季度观察)中,每季度 63 个百分点(95% CI,0.52-0.75)。在 PALLAS 试验和随后的美国食品和药物管理局黑框警告之后,Medicare Advantage 样本中与其他医生的网络连接数量高于中位数的医生每季度将决奈达隆的季度使用量减少了 0.12 个百分点(95% CI,-0.20 至 -0.04;P = 0.031)比网络连接数等于或低于中位数的医生。商业保险样本中存在类似的模式(P = 0.0318)。结论:在控制了广泛的患者、医生和地理特征后,具有更多网络连接的医生是决奈达隆更快的永久性患者停用者。 PALLAS 试验后的心房颤动和随后的美国食品和药物管理局黑框警告详细说明了决奈达隆对这些患者的危害。提高医生对新医疗信息的反应能力的政策应考虑利用这些重要的专业网络关系的影响。
