Understanding the Impact of Medicaid Delivery System Reform.

Principal Investigator: Peter J. Cunningham, Ph.D.

Funding Source: Kaiser contract

Project Summary:

The Kaiser Foundation is commissioning VCU to work in collaboration with Commission staff to conduct an analysis of delivery system financing reform for low-income populations. The project will examine how trends in preventable hospital utilization are associated with payment and delivery reforms through DSRIP (Delivery System Reform Incentive Payment) funding as well as coverage expansions. Then analysis will draw on the experience in California and can inform ongoing waiver renewal negotiations in Texas and Florida.

The analysis will draw on data on hospital admissions and emergency department (ED) visits for all Calirfornia hosptials to examine changes in the rates of preventable inpatient admissions, rates of ED visits, and changes in racial/ethnic and insurance coverage disparities in preventable hospital utilization between 2010 and 2015. In addition, it will analyze differences by county by linking hospital data to county level data on changes in the uninsured rate from the American Community Survey and information on whether there is a public hospital that received the DSRIP funding in the county.

Delivering High-Quality HIV Care in the South: System-Level Policy Alternatives

Principal Investigator: April D. Kimmel, Ph.D.

Funding Source: National Institute on Minority Health and Health Disparities

Project Summary:

While clinical care for HIV has made tremendous advances, the majority of persons living with HIV in the US do not receive the evidence-based care that will allow them to fully extend life and improve health. Lack of effective HIV care is particularly problematic in the Southern region, the epicenter of the US HIV epidemic and where poverty, uninsurance, rurality, and a constrained health workforce further threaten effective care. Research suggests that system-level factors, or the structural and policy-related aspects of health care delivery, have the potential to improve quality of care and health outcomes. But little is known about their role in the context of HIV care delivery, quality of care, and health outcomes. The proposed research will study how two modifiable system-level factors—geographic accessibility to care and physician payment policies—affect quality of HIV care and population outcomes, including new HIV infections, along the HIV care continuum in the US South. Because racial and ethnic minorities face increased barriers to HIV care, we pay special attention to how these system-level factors may contribute to disparities in quality of HIV care and population outcomes along the HIV care continuum. The research involves developing a novel database that combines multiple data sources, including Medicaid administrative claims files, HIV surveillance data, and county and state characteristics from national datasets. Our approach will rely on state-of-the-art spatial network analysis and data visualization (mapping), statistical tests using econometric methods, and systems science forecasting techniques that have been used to study quality of care and population health outcomes. The work moves beyond examination of core quality of HIV care measures to include HIV-related preventive care measures that collectively are critical to reducing HIV morbidity and mortality. In investigating these factors, the study will answer a number of important questions. How do geographic accessibility, measured in travel time to receive care, and physician payment for services affect quality of HIV care in the South? Are these effects different among racial and ethnic minorities? Do improvements in geographic accessibility or increased physician payments reduce new HIV infections and racial and ethnic disparities along the HIV care continuum? The proposed study will address these questions and others. By quantifying the role of system-level factors in quality of HIV care and population health along the HIV care continuum, as well as understanding disparities in these effects, the research will provide valuable information to state and federal policy makers who seek to address systemic challenges to effective HIV care, efficiently allocate scarce resources, and improve public health.

Central Africa International Epidemiologic Database to Evaluate AIDS (IeDEA)

Site Principal Investigator: April D. Kimmel, Ph.D.

Funding Source: National Institutes of Health: National Cancer Institute, National Institute of Allergy and Infectious Diseases, Eunice Kennedy Shriver National Institute of Child Health and Human Development, and National Institute on Drug Abuse.

Project Summary:

Elimination of HIV infection as a cause of human illness and death, and achieving "zero HIV transmission" have been embraced by the AIDS research and treatment communities as achievable. As HIV care and treatment programs are implemented throughout Africa, critical advances in research and policy are needed, so that care and treatment resources can be deployed to optimal benefit: decreasing both new HIV transmissions and HIV-related morbidity and mortality. Among the most important challenges to maximizing the public health benefits of HIV care and treatment programs are late diagnosis of HIV-infection, low rates of linkage to care, and high rates of late ART initiation which in turn ar associated with high rates of mortality, more costly clinical management and continued HIV transmission. In addition there remain unanswered clinical questions for persons living with HIV (PLWH) even with optimal ART. For PLWH in SubSaharan Africa (SSA), ART has been highly effective in decreasing HIV-related morbidity (and mortality), but the association of HIV with metabolic diseases and other conditions of aging (e.g. cancers), and the impact of under- or over-nutrition are not well defined. Newly funded as CA-IeDEA four years ago, we have built a new Central Africa IeDEA (CA- IeDEA), and have 1.) Compiled and managed secondary source patient-level data on ~52,000 patients through both extraction from existing electronic data and new on-the-ground systems for efficient capture of clinical data in low-resource clinical settings; 2.) Been highly productive scientifically with >20 publications even while data collection was in development, and 3.) have continued to foster African leadership and build local research capacity. We propose now to increase the database modestly (to ~80,000 patients) to increase the representativeness of HIV in the region geographically and in service delivery strategies and success and to expand our implementation science approaches to optimize short- and long-term HIV care outcomes both in Central Africa and globally, continue to investigate epidemiologic questions with clinical impact, with a focus on the comorbidities of aging and women's reproductive health.

Disparities in Cancer Screening: The Role of Medicaid Policy

Site Principal Investigator: Bassam A. Dahman, Ph.D.

Funding Source: National Cancer Institute and the Office of Behavioral and Social Science Research / Univerisity of Pittsburgh


There are substantial disparities in breast and cervical cancer diagnosis, treatment and outcomes in the U.S. by race, ethnicity, socio-economic and insurance status. While mortality rates have fallen over recent decades due to improved screening and treatment, these benefits are not distributed equally across the population.

Despite the existence of programs aimed at screening underserved women (e.g., the National Breast and Cervical Cancer Early Detection Program), many eligible women are not reached, and research shows that significant disparities in screening remain. Medicaid coverage for low-income women may play an important role in ensuring access to screening, though supporting evidence is limited and does not address recently enacted and proposed changes in patient eligibility, physician payment and patient cost sharing.

Study design

The study examines how existing and new policies that affect the generosity of state Medicaid programs correlate with breast and cervical cancer screening and related health outcomes among low-income women. The study will consider the effect of pre- and post-healthcare reform variation in eligibility between and within states, as well as the effect of physician payment and patient cost sharing on screening. It will also assess how the variation in Medicaid generosity across states and over time is related to outcomes including cancer incidence and stage at diagnosis.

The project brings together complementary secondary data from a number of sources. Nationally representative survey data from the Behavioral Risk Factor Surveillance System will be used to study the effects of Medicaid eligibility on breast and cervical cancer screening among low-income populations.

Medicaid administrative claims and utilization data will allow us to consider the effects of changes in eligibility as well as physician payment and patient cost sharing on screening among Medicaid enrollees. Surveillance, epidemiology and end-results cancer registry data will be used to estimate the effects of changes in Medicaid generosity on cancer incidence and stage at diagnosis.

Intended policy outcomes

Findings from this study will provide evidence about the impact of public policies on cancer screening for underserved populations. The study will be the first to explore the effects of recent Medicaid policies on breast and cervical cancer screening and diagnosis among low-income women. The outcomes considered will also serve as an indicator of the effect of health reform on prevention and women’s health.

Incentives to Encourage Primary Care Use: A Randomized Controlled Trial in Safety Net

Principal Investigator: Maria Thomson, Ph.D.

Funding Source: Agency for Healthcare Research and Quality, U.S. Department of Health and Human Services. Grant No. R01HS022534

The study supports a randomized controlled trial of incentives for an initial primary care visit within six months of enrollment in a healthcare coverage program. The lack of healthcare coverage leads to poor health and inappropriate healthcare use among the uninsured. Medicaid expansions to the uninsured adult population are a means of improving access to primary care. However, the evidence from these expansions on reducing hospitalizations and emergency department use is mixed, suggesting that barriers to primary care remain, in spite of coverage.  Interventions, such as incentives (also known as conditional cash transfers), may be a means to steer patients toward a model of care that emphasizes prevention, primary care for nonemergent needs and primary care chronic disease management. Cash incentives may generate a desired behavioral response for a relatively small price.
