新的处方药是美国支出增长的主要驱动力。对于患有严重精神疾病的患者,第二代抗精神病药物(SGA)的特点突出。然而,许多SGAs价格昂贵,特别是在进入仿制药之前,有些SGAs可能会增加糖尿病的风险。由于医生在新处方的采用中发挥着重要作用,因此了解他们的处方行为与政策相关。处方数据的几个特征,例如随着时间的推移不同的抗精神病药物选择集,可变的医生处方量,以及医生内药物选择之间的相关性,使推断复杂化。我们提出了一个多变量贝叶斯分层模型与分段随机效应来表征新的抗精神病药物的扩散。该模型捕捉了不同扩散过程之间复杂的处方特定关系,并利用贝叶斯范式直接量化所有参数的不确定性。为了评估每个医生的处方模式,我们提出了各种指数,以确定早期新的SGA采用者。在1997年1月1日至2007年12月31日期间收集了近17,000名美国医生的抗精神病药物处方信息的样本说明了方法。高处方率和采用速度的新的SGAs的决定因素包括医生的性别,年龄,医院隶属关系,医生的专业,和办公室的位置。在新的SGAs处方模式中,发现了提供者内部和提供者之间的巨大差异。一种药物的早期采用者并不是另一种药物的早期采用者。
New prescription medications are a primary driver of spending growth in the United States. For patients with severe mental illnesses, second generation antipsychotic (SGA) medications feature prominently. However, many SGAs are costly, particularly before generic entry, and some may increase the risk of diabetes. Because physicians play a prominent role in new prescription adoption, understanding their prescribing behaviors is policy-relevant. Several features of prescription data, such as different antipsychotic choice sets over time, variable physician prescription volumes, and correlation among drug choices within physicians, complicate inferences. We propose a multivariate Bayesian hierarchical model with piecewise random effects to characterize the diffusion of new antipsychotic drugs. This model captures the complex prescriber-specific relationships among the different diffusion processes and takes advantage of the Bayesian paradigm to quantify uncertainty for all parameters straightforwardly. To evaluate the prescribing patterns for each physician, we propose various indices to identify early new SGA adopters. A sample of nearly 17,000 U.S. physicians whose antipsychotic drug prescribing information was collected between January 1, 1997 and December 31, 2007 illustrates the methods. Determinants of high prescription rates and adoption speeds of new SGAs included physician sex, age, hospital affiliation, physician specialty, and office location. Large within- and between-provider variations in prescribing patterns of new SGAs were identified. Early adopters for one drug were not early adopters for another drug.
