Market competition may not reduce costs or lead to greater efficiency in hospitals

The U.S. has the most expensive per capita health care system in the world. As such, one of the main goals of the Affordable Care Act (ACA) is to reduce costs for citizens. Morgen S. Johansen and Ling Zhu examine how private, non-profit, and government-run hospitals have responded to local market competition and the ACA. They find that administrators from public, non-profit, and private hospitals prioritize different aspects of care and costs in the face of market competition and that public hospitals are much more responsive to the ACA reforms

The refusal of 24 states to expand Medicaid under Obamacare will maintain their high levels of inequality in healthcare coverage

The United States is the only industrialized democracy that does not have universal health care coverage, and nearly one in five Americans do not have health insurance. The Affordable Care Act (commonly known as ‘Obamacare’) aims to extend health insurance to under and uninsured Americans by having them enroll in state or national “exchanges,” or online marketplaces; and by providing federal funds to states to expand their Medicaid coverage. Since the Act is implemented predominantly by the states, the benefits of the Act for uninsured Americans depends heavily on what states do, or refuse to do with Medicaid coverage and the state exchanges. Ling Zhu and Morgen Johansen examine what the U.S. states can do to address inequality in health insurance coverage

The Effects of Elite Decision Making

Decision making is a central concept in the study of both politics and organizations. Although much research has examined how individuals make decisions, there has been substantially less work on the consequences of these decisions. My dissertation focuses on two groups of decision makers, candidates running for office and public managers, and the effect of their decisions on the electorate and organization, respectively. The dissertation explores the impact of candidates' decisions regarding their campaigns on the electorate by examining campaign advertising during the 2000 Presidential Election. I focus on two candidate decisions. The first is to focus on certain issues as a way to prime the public to see the candidate as having certain traits, namely empathy, morality, and leadership ability. The second is to show voters that the candidate is like them by activating (i.e. priming) feelings of social identity among women, African-Americans, and Latinos. Using campaign advertising data and public opinion data, I analyze the effect of campaign advertising on voters' evaluations of the candidates to determine the effectiveness of these strategies. Results find that an effective strategy was for the candidates to air ads describing themselves as having certain traits. Talking about issues does not have much of an effect on voters' candidate evaluations. Appeals to women were not effective. Appeals to African-Americans were only effective for the Democratic candidate, and appeals to Latinos were only successful for the Republican candidate. I examine the decisions of public managers by focusing on middle level bureaucrats and the consequences of their decisions on their agencies. The agencies are public schools in Texas and the middle managers are principals. From a dataset of over 1,000 Texas school districts, I create a measure of principal quality which I then use to explore the impact of middle management on multiple school performance measures and to compare the influence of principals and superintendents on performance. I also examine the effect of principals within in the organization, namely how principals affect the turnover of the workers under them. Results find that principals have a direct and beneficial influence on organizational performance measures such as standardized test scores, college readiness, and turnover. To summarize the results more generally, the dissertation finds that the decisions actors make within the political process matter in important and significant ways

Neuroplasticity and functional recovery in multiple sclerosis

The development of therapeutic strategies that promote functional recovery is a major goal of multiple sclerosis (MS) research. Neuroscientific and methodological advances have improved our understanding of the brain's recovery from damage, generating novel hypotheses about potential targets and modes of intervention, and laying the foundation for development of scientifically informed recovery-promoting strategies in interventional studies. This Review aims to encourage the transition from characterization of recovery mechanisms to development of strategies that promote recovery in MS. We discuss current evidence for functional reorganization that underlies recovery and its implications for development of new recovery-oriented strategies in MS. Promotion of functional recovery requires an improved understanding of recovery mechanisms that can be modulated by interventions and the development of robust measurements of therapeutic effects. As imaging methods can be used to measure functional and structural alterations associated with recovery, this Review discusses their use to obtain reliable markers of the effects of interventions

Rivaroxaban with or without aspirin in stable cardiovascular disease

BACKGROUND: We evaluated whether rivaroxaban alone or in combination with aspirin would be more effective than aspirin alone for secondary cardiovascular prevention. METHODS: In this double-blind trial, we randomly assigned 27,395 participants with stable atherosclerotic vascular disease to receive rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg once daily), rivaroxaban (5 mg twice daily), or aspirin (100 mg once daily). The primary outcome was a composite of cardiovascular death, stroke, or myocardial infarction. The study was stopped for superiority of the rivaroxaban-plus-aspirin group after a mean follow-up of 23 months. RESULTS: The primary outcome occurred in fewer patients in the rivaroxaban-plus-aspirin group than in the aspirin-alone group (379 patients [4.1%] vs. 496 patients [5.4%]; hazard ratio, 0.76; 95% confidence interval [CI], 0.66 to 0.86; P<0.001; z=−4.126), but major bleeding events occurred in more patients in the rivaroxaban-plus-aspirin group (288 patients [3.1%] vs. 170 patients [1.9%]; hazard ratio, 1.70; 95% CI, 1.40 to 2.05; P<0.001). There was no significant difference in intracranial or fatal bleeding between these two groups. There were 313 deaths (3.4%) in the rivaroxaban-plus-aspirin group as compared with 378 (4.1%) in the aspirin-alone group (hazard ratio, 0.82; 95% CI, 0.71 to 0.96; P=0.01; threshold P value for significance, 0.0025). The primary outcome did not occur in significantly fewer patients in the rivaroxaban-alone group than in the aspirin-alone group, but major bleeding events occurred in more patients in the rivaroxaban-alone group. CONCLUSIONS: Among patients with stable atherosclerotic vascular disease, those assigned to rivaroxaban (2.5 mg twice daily) plus aspirin had better cardiovascular outcomes and more major bleeding events than those assigned to aspirin alone. Rivaroxaban (5 mg twice daily) alone did not result in better cardiovascular outcomes than aspirin alone and resulted in more major bleeding events
