项目摘要

Summary/Abstract Diabetic lower extremity (DLE) wounds affect up to 34% of adults with diabetes and are associated with substantial clinical morbidity/mortality, increased healthcare utilization, and higher cost of care. However, persistent racial/ethnic and socioeconomic disparities among DLE wounds remain poorly addressed, and little is known about the utilization of physician services and role of physician networks in observed disparities. This proposal responds to PAR-20-310, Health Services Research on Minority Health and Health Disparities, by conducting a national evaluation of racial/ethnic and socioeconomic disparities in healthcare utilization among patients with DLE wounds, and assessing the role that physician networks and referral patterns play in observed disparities. Through the RAND AHRQ U19 Center of Excellence on Health System Performance, our study will leverage several Medicare data sources, unique physician-level preliminary data, and innovative methods to improve beneficiary classification of race/ethnicity. The study will focus on Medicare fee-for-service beneficiaries aged 65 years and older with a new DLE wound and track longitudinal utilization of healthcare services across multiple clinical settings during the 6-month period following initial wound diagnosis. In Aim 1, we will use multivariable regression techniques to evaluate racial/ethnic and socioeconomic disparities in healthcare utilization after initial DLE wound diagnosis. Then, we will map and characterize physician networks and referral patterns for DLE wounds and examine the effects of network/referral pattern characteristics on healthcare utilization disparities (Aim 2). Finally, in Aim 3, we will simulate changes to network/referral pattern characteristics and identify which characteristics have stronger disparity reducing effects, and therefore, are amenable to intervention development. The proposed study will identify potentially modifiable aspects of physician networks and referral patterns that contribute to observed disparities in DLE wound care. Results will inform how policy regarding physician network adequacy, health system organization, and payer incentives can improve quality of care for patients with DLE wounds and reduce disparities in healthcare utilization. The project team consists of multiple NIH funded researchers with ample expertise in health disparities research, network analysis of claims data, statistical methods, and knowledge of clinical context.

摘要/摘要糖尿病下肢（DLE）伤口最多影响34％的糖尿病成年人大量的临床发病率/死亡率，增加医疗保健利用和更高的护理成本。然而， DLE伤口之间持续存在的种族/种族和社会经济差异仍然很差，很少了解医师服务的利用以及医师网络在观察到的差异中的作用。这提案对20-310 Par-310，《少数民族健康和健康差异的健康服务研究》作出回应，对医疗保健利用中的种族/种族和社会经济差异进行全国性评估患有DLE伤口的患者，并评估医师网络和推荐模式在观察到的差异。通过Rand AHRQ U19卫生系统绩效卓越中心，我们研究将利用几种医疗保险数据来源，独特的医师级别的初步数据和创新性改善种族/民族的受益人分类的方法。该研究将重点放在医疗保险费用上 65岁及以上的受益人带有新的DLE伤口，并追踪了医疗保健的纵向利用在最初伤口诊断后的6个月内，多个临床环境的服务。在AIM 1中，我们将使用多变量回归技术来评估种族/种族和社会经济差异初始DLE伤口诊断后的医疗保健利用。然后，我们将映射和表征医师网络以及DLE伤口的转介模式，并检查网络/推荐模式特征对医疗保健利用差异（AIM 2）。最后，在AIM 3中，我们将模拟对网络/推荐模式的更改特征并确定哪些特征具有更强的差异降低效果，因此是适合干预开发。拟议的研究将确定可能修改的方面医师网络和转诊模式导致了DLE伤口护理中观察到的差异。结果将告知有关医师网络充分性，卫生系统组织和付款人激励措施的政策可以改善伤口伤口患者的护理质量，并减少医疗保健利用率的差异。这项目团队由多个具有NIH资助的研究人员组成，具有丰富的健康差异研究专业知识，索赔数据，统计方法和临床环境知识的网络分析。
