The implications and impact of 3 approaches to health information exchange: community, enterprise, and vendor‐mediated health information exchange

IntroductionElectronic health information exchange (HIE) is considered essential to establishing a learning health system, reducing medical errors, and improving efficiency, but establishment of widespread, high functioning HIE has been challenging. Healthcare organizations now have considerable flexibility in selecting among several HIE strategies, most prominently community HIE, enterprise HIE (led by a healthcare organization), and electronic health record vendor‐mediated HIE. Each of these strategies is characterized by different conveners, capabilities, and motivations and may have different abilities to facilitate improved patient care.MethodsI reviewed the available scholarly literature to draw conceptual distinctions between these types of HIE, to assess the current evidence on each type of HIE, and to indicate important areas of future research.ResultsWhile community HIE seems to offer the most open approach to HIE allowing for high levels of connectivity, both enterprise HIE and vendor‐mediated HIE face lower barriers to formation and sustainability. Most existing evidence is focused on community HIE and points towards low overall use, challenges to usability, and ambiguous impact. To better guide organizational leaders and policymakers in the expansion of beneficial HIE and anticipate future trends, future research should work to better capture the prevalence of other forms of HIE, and to adopt common methods to allow comparisons of rate of use, usability, and impact on patient care across studies and types of HIE.ConclusionsHealthcare organizations’ choice of HIE strategy influences the set of partners the organization is connected to and may influence the benefit that efforts supported by HIE can offer to patients. Current research is not fully capturing the diversity of approaches to HIE and their potentially varying impact on providers and patients.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/136725/1/lrh210021_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/136725/2/lrh210021.pd

Physician Behavior In Accountable Care Organizations

This dissertation studies how performance risk-based (i.e., value-based) reimbursement over total costs of care in health insurance contracting affects how providers, specifically physician groups and health systems, determine marginal treatment choice and set the level of care provided to patients. Utilizing the widespread adoption of Accountable Care Organization (ACO) contracts by both commercial payers and Medicare, presented research explores changes in care delivery and health system organization when risks for total costs of care and satisfactory attainment of specific quality metrics (i.e. an ACO contract) are offered to providers. This dissertation proceeds in five parts. First, I review the substantial literatures related to the specific characteristics of ACO contracts in addition to the institutional details of such contracts themselves. Next, leveraging optimal procurement and auction theory, I present a theoretical foundation for considering ACOs as a form of incentive contract auction by Medicare and other insurers. This theoretical foundation motivates three principal empirical analyses of ACO contracts, each briefly explained in the preface, focused on changes in physician behavior following ACO contract adoption

Making Medical Homes Work: Moving From Concept to Practice

Explores practical considerations for implementing a medical home program of physician practices committed to coordinating and integrating care based on patient needs and priorities, such as how to qualify medical homes and how to match patients to them

Hospital Networks of Shared Patients and Engagement in Health Information Exchange

Although the healthcare delivery system is composed of an array of organizations that are linked through important, enduring, and complex ties, the healthcare delivery system is rarely explicitly conceptualized or measured as a network. In consequence, we know little about how the enduring but often informal relationships between organizations shape their behavior in terms of the decisions that they make, the quality of care that they provide, and the efficiency of that care. Using techniques developed in the multidisciplinary field of network analysis, I sought to better understand two important facets of health care that are intrinsically linked to the network perspective: the fragmentation of patients’ treatments between multiple hospitals, and hospitals engagement in electronically sharing patient information. By analyzing networks of shared Medicare patients treated at multiple hospitals, I first identified dense networks of hospitals that are closely interlinked through many high volume shared patient connections and are therefore likely linked through complex collaborative and competitive relationships. I then characterized these networks to identify arrangements of patient sharing that allowed hospitals to better manage care fragmentation. I found that more concentrated networks, in which hospitals shared most of their patients with few important partners rather than a large number of other hospitals, and more centralized networks, in which the network is arranged in a hub-and-spoke model, were associated with more efficient, higher quality care. I next described three different approaches to health information exchange and the logic of participation in each approach with specific emphasis on the value of the enterprise approach for connecting a smaller number of providers and the community approach for facilitating broader connections between more partners. I then investigated whether the choice that hospitals made about how to electronically share patient information was shaped by their networks. I found that hospitals with and within more concentrated patient sharing networks were more likely to engage in enterprise exchange while hospitals with and within less concentrated networks engaged in community exchange more frequently. Together, these findings offer novel insights into the network features of hospitals and how they relate to important healthcare processes and outcomes. More concentrated, centralized networks appear to perform better and these features may be one reason for variation in the cost and quality of care across the nation. Similarly, policy changes designed to shape how healthcare organizations interact and who they interact with—like accountable care organizations, bundled payment initiatives and patient center medical homes—may be more successful if they reinforce beneficial network attributes. Further, as policy efforts designed to facilitate the sharing of information between healthcare providers continue, it will be crucial to allow flexible adoption of different approaches to health information exchange and to support hospitals that engage in an approach to information exchange that benefits communities.PHDHealth Services Organization & PolicyUniversity of Michigan, Horace H.

Health Care Crisis: Potential Solutions to the Perverse Reimbursement System and the Fragmented Care Delivery System

The American health care system is in a serious crisis. We have very high health care expenditures, but receive very low quality health outcomes. It is time for America to address the problems of our health care system head on, starting with the fee-for-service reimbursement structure and the fragmented care delivery system. This paper provides a comparative analysis of the systems in place in France and Japan to draw conclusions about possible solutions for the United States. This paper also discusses successful health care institutions within America and why they work. Finally, the potential results of the Affordable Care Act are discussed

New perspectives for hypertension management: progress in methodological and technological developments

: Hypertension is the most common and preventable risk factor for cardiovascular disease (CVD), accounting for 20% of deaths worldwide. However, 2/3 of people with hypertension are undiagnosed, untreated, or under treated. A multi-pronged approach is needed to improve hypertension management. Elevated blood pressure (BP) in childhood is a predictor of hypertension and CVD in adulthood; therefore, screening and education programmes should start early and continue throughout the lifespan. Home BP monitoring can be used to engage patients and improve BP control rates. Progress in imaging technology allows for the detection of preclinical disease, which may help identify patients who are at greatest risk of CV events. There is a need to optimize the use of current BP control strategies including lifestyle modifications, antihypertensive agents, and devices. Reducing the complexity of pharmacological therapy using single-pill combinations can improve patient adherence and BP control and may reduce physician inertia. Other strategies that can improve patient adherence include education and reassurance to address misconceptions, engaging patients in management decisions, and using digital tools. Strategies to improve physician therapeutic inertia, such as reminders, education, physician-peer visits, and task-sharing may improve BP control rates. Digital health technologies, such as telemonitoring, wearables, and other mobile health platforms, are becoming frequently adopted tools in hypertension management, particularly those that have undergone regulatory approval. Finally, to fight the consequences of hypertension on a global scale, healthcare system approaches to cardiovascular risk factor management are needed. Government policies should promote routine BP screening, salt-, sugar-, and alcohol reduction programmes, encourage physical activity, and target obesity control
