No study has examined Prescription Drug Monitoring Program (PDMP) data for West Virginia or among specialty practices, such as veterinary medicine. The objectives of this study were to conduct time series modeling to describe the PDMP policy reform impact on prescribing rates for human and veterinary providers. We obtained data from the WV PDMP for 2008 through 2020 for the number of opioid prescriptions filled and providers. We estimated prescribing rates for human and veterinary providers separately based upon the top five opioids prescribed by veterinarians. We estimated temporal effects using a Bayesian log-normal time series model for humans and veterinarians separately. Throughout the study period prescribing rates increased significantly for veterinarians, and decreased for human providers, particularly during 2018 after implementation of the Opioid Reduction Act. Findings provide novel insight into the differential impact of policy on specialty practices and highlight decreasing human opioid prescribing observed elsewhere.
尚无研究针对西弗吉尼亚州或兽医等专业实践的处方药物监测计划 (PDMP) 数据进行审查。本研究的目的是进行时间序列建模，以描述 PDMP 政策改革对人类和兽医提供者开出处方率的影响。我们从 WV PDMP 获得了 2008 年至 2020 年期间用于填充和提供者的阿片类药物处方数量的数据。我们根据兽医开的前五种阿片类药物，分别为人类和兽医提供者估算开出处方率。我们分别使用贝叶斯对数正态时间序列模型估算时间效应。在整个研究期间，兽医的处方率显著增加，而人类提供者的处方率下降，尤其是在 2018 年《阿片类药物减少法案》实施后。研究结果提供了有关政策对专业实践的差异化影响的新见解，并强调了在其他地方观察到的人类阿片类药物开出处方率下降的情况。
