项目摘要
PROJECT SUMMARY
Over the past 40 years, specialist physicians have supplanted primary care as the most frequently seen
clinicians for older adults in the US. This shift towards specialty care is driven by advancing medical technology
and increased “subspecialization,” whereby specialist physicians focus on narrower and narrower clinical
areas. Subspecialization has grown markedly: in 1980, the American Board of Medical Specialties had 28
specialty boards, with an additional 28 certified subspecialties. By 2020, 40 specialty boards encompassed 147
separate subspecialties. While subspecialists bring greater clinical expertise, too much subspecialization could
lead to inequitable access, overtreatment, overdiagnosis or fragmentation of care. There is little empirical
evidence on the implications of growing subspecialization for the health of older Americans.
A major obstacle to filling these evidence gaps is the lack of meaningful measures of subspecialization
at the physician level. Existing physician directories, like the one used by Medicare, contain in-depth specialty
data, but are also highly inaccurate. For example, Medicare data identify only 17% of board-certified advanced
heart failure specialists in the US. Other specialties have similar data gaps. To understand how access to
subspecialists influences access to specific advanced treatments and clinical outcomes, it is necessary to
better define the hundreds of types of subspecialty care being provided to patients.
We propose to characterize subspecialization in the US and assess its implications for the health and
health care of older adults. Using comprehensive data from Medicare, we will develop novel methods to
classify physician subspecialists by their observed practice patterns, focusing on 3 key specialties in the care
of older adults (cardiology, medical oncology and general surgery) as “tracer” disciplines to fill evidence gaps in
subspecialty care that can inform policy. Specifically, we will:
1) Use community detection algorithms, a common tool in network science, to identify subspecialists based on
their practice patterns (as measured by services provided, drug treatments, and patient diagnoses).
2) Identify patient, health system and geographic factors associated with subspecialty supply and access.
3) Using quasi-experimental methods, measure the impact of access to subspecialist care on health outcomes
and utilization in the three key specialties.
These Aims will provide novel evidence to guide health policy, including improved methods to
accurately measure subspecialist supply, guide health insurers and policymakers for applications such as
determining adequacy of specialist coverage in insurance design (e.g., Medicare Advantage), identify
populations with shortages in subspecialist access, and guide telemedicine development. Without this
evidence, clinical advances may not reach older adults who could benefit the most.
项目摘要
在过去的40年里,专科医生已经取代初级保健成为最常见的
美国老年人的临床医生。这种向专科护理的转变是由先进的医疗技术推动的
和增加“亚专业化”,即专科医生专注于越来越窄的临床
地区亚专业化显著增长:1980年,美国医学专业委员会有28个
专业委员会,与额外的28个认证的亚专业。到2020年,40个专业委员会涵盖147个
独立的亚专业虽然专科医生带来了更多的临床专业知识,但太多的专科医生可能会
导致获得机会不公平、过度治疗、过度诊断或护理支离破碎。几乎没有经验性的
证据表明,越来越多的亚专业化对美国老年人健康的影响。
填补这些证据空白的一个主要障碍是缺乏有意义的亚专业化措施
在医生的层面上。现有的医生目录,如医疗保险使用的目录,包含深入的专业
数据,但也非常不准确。例如,医疗保险数据仅识别出17%的董事会认证的高级医疗保险。
美国的心脏病专家。其他专业也有类似的数据缺口。要了解如何访问
亚专科医生影响获得特定的先进治疗和临床结果,有必要
更好地定义为患者提供的数百种专科护理。
我们建议描述美国的亚专业化,并评估其对健康和
老年人的保健。利用医疗保险的综合数据,我们将开发新的方法,
根据观察到的实践模式对医生亚专科进行分类,重点关注护理中的3个关键专科
老年人(心脏病学,内科肿瘤学和普通外科)作为“示踪”学科,以填补证据空白,
可以为政策提供信息的专科护理。具体而言,我们将:
1)使用社区检测算法(网络科学中的常用工具),
他们的实践模式(通过提供的服务,药物治疗和患者诊断来衡量)。
2)确定与专科供应和获取相关的患者、卫生系统和地理因素。
3)使用准实验方法,测量获得亚专科护理对健康结果的影响
在三个重点专业的应用。
这些目标将为指导卫生政策提供新的证据,包括改进方法,
准确衡量专科供应,指导医疗保险公司和政策制定者的应用,
在保险设计中确定专家保险的充分性(例如,Medicare Advantage),识别
该项目旨在帮助缺乏专科医生服务的人口,并指导远程医疗的发展。没有这个
然而,临床进展可能无法达到老年人谁可以受益最多。
