Transforming Health Care Through Evidence and Collaboration
Transforming Health Care Through Evidence and Collaboration

This study builds on prior work by this team to construct indices of systemic overuse in geographic regions for the Medicare and commercially insured populations and forms the first step in a new phase of work designed to understand systemic overuse and efficiency within individual health systems. This work is expected to contribute to the knowledge base on overuse and has the potential to identify effective strategies to improve value closer to the point of care delivery.


This study aims to provide evidence on (1) variation in the quality of care provided to patients visiting emergency departments (EDs) for behavioral health conditions and (2) the relationship between facility capacity to provide behavioral health care and use of involuntary detentions for patients presenting for care. Findings have the potential to enhance our understanding of how behavioral health services are provided in EDs and improve the care provided in this setting for patients with behavioral health conditions.


This study is designed to (1) learn more about state and federal barriers that may be inhibiting federally-qualified health centers (FQHCs) from using telehealth to deliver medication assisted treatment (MAT) for opioid use disorder; (2) identify best practices from FQHCs that are successfully using telehealth for MAT; (3) identify planned or implemented state and federal strategies to overcome barriers; and (4) draw out lessons and formulate recommendations for operational and/or policy solutions. This work holds the potential to help ensure that remotely-located patients have access to a proven approach to treating opioid use disorder.


This study will examine the impact of the Arkansas Medicaid expansion on full-year postpartum use of outpatient care, emergency department visits and inpatient stays for severe maternal morbidities, and test whether the Medicaid expansion reduced racial disparities in these outcomes. Results are expected to inform deliberations regarding proposed state and federal legislation to provide up to one-year of pregnancy-related Medicaid coverage for postpartum women.


This study will develop and estimate a structural model of bargaining and pricing for pharmaceuticals in order to assess how adoption of an international reference pricing policy by the U.S. would likely affect equilibrium prices in the U.S. and in referenced countries. The modeling approach will consider the impact of possible retaliatory pricing policies in referenced countries and the dynamic impacts on generic entry.


This study will use enrollment data from the Colorado exchange to study how the advent of zero-premium plans affected (1) insurance take-up among different demographic groups and (2) the types of health plans chosen by enrollees. Models will isolate the impact of premium levels vs. zero-price plans and also examine the impact of inertia that makes current enrollees less likely to change plan choice in response to premium changes. Study results will be relevant to current policy proposals such as public options, Medicaid buy-ins and higher premium subsidies that may result in more people having access to zero-premium plans.


This study will investigate the impact of mergers between drug manufacturers and between pharmacy benefits managers (PBMs) on prices of drugs and on patient access to drugs as dictated by formularies. The model of drug price negotiation between manufacturers and PBMs that will be developed in this study will support assessment of the potential pricing and access effects of future mergers and other policy changes, and can help regulators to improve antitrust screening.


This study seeks to enhance understanding of the observed geographic variation in Medicare and commercial health care spending and utilization. Specifically, the work will investigate whether geographic variations in physician practice style are driving variations in spending and utilization or whether these variations are due to different financial incentives inherent in the reimbursement schedules of different payers. Findings related to how physicians behave at the micro level will enhance the understanding of geographic variations.
