Impact of the Diffusion of Robotic Surgical Systems on the Financial Performance, Market Shares, and Inpatient Costs of U.S. Hospitals

 描述(申请人提供)：在过去的十年里，机器人辅助手术变得越来越流行。美国的许多医院已经购买了机器人手术系统，更多的医院正在考虑购买这种设备。这种机器的价格最高可达250万美元。鉴于采购成本如此之高，研究这项新技术的传播如何影响美国医疗体系是很重要的。使用我们为加州医院汇编的独特数据库，我们将使用最先进的计量经济学方法来解决以下具体目标：1：检查与医院决定购买机器人手术系统相关的医院和市场特征。2：探索收购机器人手术系统如何影响同一市场内以及不同机器人手术能力市场之间的医院之间的手术流量和成本。3：从医院的运营费用和收入方面评估购买机器人手术机器对财务业绩的影响。这项研究的结果将告诉决策者机器人系统的扩散如何影响医院的手术实践和成本，还可以帮助医院的决策者就是否购买机器人手术系统做出更理性的决定。

 DESCRIPTION (provided by applicant): Robot-assisted surgeries have become increasingly popular over the past decade. Many hospitals in the United States have acquired robotic surgical systems and more are considering purchasing this equipment. The price of such machines can be up to $2.5 million. Given such high acquisition costs, it is important to study how the diffusion of this new technology affects the U.S. healthcare system. Using a unique database we compiled for hospitals in California, we will employ state-of-the-art econometric methods to address the following specific aims: 1: To examine hospital and market characteristics associated with hospitals' decision to acquire a robotic surgical system. 2: To explore how the acquisition of robotic surgical system affect the flow and cost of surgeries among hospitals within the same market as well as across markets with varying capacity of robotic surgeries. 3: To evaluate how the purchase of robotic surgical machines affects the financial performance in terms of operating expenses and revenue of hospitals. Findings from this study will inform policy makers how the proliferation of robotic systems affects surgical practice and costs in hospital settings and can also help decision makers at hospitals make more rational decision regarding whether to purchase robotic surgical systems.
