DESCRIPTION (provided by applicant): Physicians, both directly through services they provide and indirectly through the services that they order, shape the vast majority of health care utilization in the US. There has long been intense interest in the determinants of physician decision making because optimizing physician decisions has the potential to improve the quality of US health care while also controlling costs by eliminating the use of unnecessary services. One influence on physician decision making that has largely been ignored derives from the influence of networks of physicians on individual physician decision making. Here, we are using the term "network" in a technical sense to refer to informal networks of primary care and specialist physicians who share patients and information, rather than formal networks of all of the physicians formally affiliated with a health plan or hospital. By virtue of sharing patients, these networks can be defined empirically. Networks of physicians have the potential to influence an individual physician's decision making, but such influences have rarely been studied. In this application, we propose to develop a longitudinal database of physician networks over time and to apply the methods we have developed in defining and describing physician networks to understand diffusion of cancer care practices across these networks. We propose to use Medicare data from 2005 through 2009 to evaluate the contribution of physician networks to variations in the adoption and use of innovations in oncology care as well as hospice use for terminally-ill cancer patients. We also plan additional analyses that will combine data from the Surveillance, Epidemiology and End Results (SEER) Program with our data on physician networks in those areas to examine the appropriateness of the adoption and use of new cancer treatments. The specific aims of the proposal are to: 1) Examine the extent to which network properties predict diffusion of new cancer therapies, focusing on the diffusion of new biologic therapies for cancer; 2) Examine the extent to which network properties predict local variations in the use of hospice; and 3) Examine the extent to which network properties predict the appropriateness of the diffusion of new therapies.

描述（由申请人提供）：医生，直接通过他们提供的服务和间接通过他们订购的服务，塑造了美国绝大多数医疗保健利用率。长期以来，人们一直对医生决策的决定因素有着浓厚的兴趣，因为优化医生决策有可能提高美国医疗保健的质量，同时通过消除不必要的服务来控制成本。 一个影响医生的决策，在很大程度上被忽视，来自网络的医生对个人医生的决策的影响。在这里，我们使用的术语“网络”在技术意义上是指初级保健和专科医生的非正式网络，他们分享病人和信息，而不是正式的网络，所有的医生正式隶属于一个健康计划或医院。由于共享病人，这些网络可以根据经验定义。医生网络有可能影响个别医生的决策，但这种影响很少被研究。 在这个应用程序中，我们建议开发一个纵向数据库的医生网络随着时间的推移，并应用我们已经开发的定义和描述医生网络的方法，以了解扩散的癌症护理实践在这些网络。我们建议使用2005年至2009年的医疗保险数据，以评估医生网络的贡献，在采用和使用创新的肿瘤护理以及临终关怀使用的晚期癌症患者的变化。我们还计划进行额外的分析，将联合收割机的监测，流行病学和最终结果（SEER）计划的数据与我们在这些地区的医生网络的数据相结合，以检查采用和使用新的癌症治疗方法的适当性。该提案的具体目标是：1）检查网络属性预测新癌症疗法扩散的程度，重点是癌症新生物疗法的扩散; 2）检查网络属性预测使用临终关怀的局部变化的程度; 3）检查网络属性预测新疗法扩散的适当性的程度。
