Peterson was a founding team member of the Blue Sky Health Initiative to transform the U.S. health and health care system, which advised Congress and the executive branch on the inclusion of population health strategies in the Affordable Care Act. As an American Political Science Association (APSA) Congressional Fellow, he was a legislative assistant for health policy for U.S. Senator Tom Daschle. He is currently on the Faculty Task Force of the California Health Benefits Review Program. He also served on the National Academy of Social Insurance's Study Panel on Medicare and Markets and on the Health Policy Advisory Committee for the Barack Obama for President Campaign. He chaired the National Advisory Committees for the Robert Wood Johnson Foundation's Scholars in Health Policy Research program and its Changes in Health Care Financing and Organization (HCFO) program, and was a member of the National Advisory Committees for RWJF’s Investigator Awards in Health Policy Research Program and Center for Health Policy at the University of New Mexico.

A past elected member of the Council of the American Political Science Association, Peterson is a founding member of the Association's Organized Section on Health Politics and Policy, and was elected president of its Organized Section on Public Policy. He has chaired the University of California Academic Senate's Health Care Task Force. Peterson is an elected member of the National Academy of Social Insurance and recipient of the Richard E. Neustadt Award from the APSA's Presidents and Executive Organized Section, the APSA's E. E.

Opening Doors for All: Improving Health in Housing and Homelessness

Summary: California’s current homelessness crisis is unprecedented. In early 2020, more than 160,000 persons experienced homelessness on any given day, representing a 40% increase since 2015. Effects on individuals experiencing housing insecurity and the community's public health have been profound, including recent outbreaks of hepatitis A and typhus in communities experiencing homelessness.

The UCLA Center for Health Policy Research (CHPR) convened a virtual event to bring together key voices highlighting evidence-based strategies to help address this crisis at a time when state lawmakers have a significant budget surplus available to potentially invest in addressing this crisis. Focusing on the intersection of health and homelessness, the 2021 E.R. Brown Symposium, Opening Doors for All: Improving Health in Housing and Homelessness featured experts from academia, state and local government, nonprofit organizations, the private sector, and speakers with lived experience in two days of discussions on past successes, lessons learned, and potential solutions to create a healthier, more prosperous California for all.

This new policy paper outlines evidence-based strategies shared by local, state, and national leaders to help address the homelessness crisis in California.

Medicare and Medicaid at 50: America's Entitlement Programs in the Age of Affordable Care

​UCLA Faculty Associate Mark Peterson has a chapter "The Third Rail of Politics? Medicare's Untouchability" in this book assessing Medicare and Medicaid at 50, edited by Alan B. Cohen, et al.

For 50 years, Medicare and Medicaid have stood at the center of a contentious debate surrounding American government, citizenship, and health care entitlement. In Medicare and Medicaid at 50, leading scholars in politics, government, economics, health policy, and history offer a comprehensive assessment of the evolution of these programs and their impact on society — from their origins in the Great Society era to the current battles over the Affordable Care Act.

A Population-Based Survey of Prostate-Specific Antigen Testing Among California Men at Higher Risk for Prostate Carcinoma (Cancer)

BACKGROUND: Despite the lack of evidence demonstrating a survival benefit from prostate-specific antigen (PSA) screening, its use has become widespread, organizations have encouraged physicians to discuss early detection of prostate carcinoma, and two higher risk groups have been recognized. In the current study, the authors examined whether African-American men and men who had a family history of prostate carcinoma underwent PSA testing preferentially, and patterns of test use were examined according to age, race, and other factors.   METHODS: Data regarding self-reported PSA test use in the past year among men age 50 years and older without a history of prostate carcinoma (n = 8713 men) were analyzed from the 2001 California Health Interview Survey.   RESULTS: The overall rate of PSA use was 43.0%. Older age, higher socioeconomic status, having a usual source of healthcare, and a family history of prostate carcinoma were the strongest predictors of testing. Higher risk African-American men age 50 years and older were no more likely to be tested than white men. Men at higher risk who had a family history of prostate carcinoma were more likely to have been tested than men who had no such family history.   CONCLUSIONS: Rates of PSA use among higher risk men who had a family history of prostate carcinoma were higher compared with the rates among men without such a family history. However, PSA testing rates among higher risk African-American men were no different than the rates among lower risk white men, suggesting that some risk factors for prostate carcinoma (but not others) are associated with preferential testing. Testing in all groups was associated with access to care variables, highlighting the importance of removing barriers to preventive healthcare services.   Spencer BA, Babey SH, Etzioni DA, Ponce NA, Brown ER, Yu H, Chawla N, Litwin MS.

If Trump cuts Medicaid, this California Republican’s House seat would be imperiled

UCLA Center for Health Policy senior fellow Mark A. Peterson is quoted in this article about the potential consequences facing U.S. Rep. David Valadao as he prepares to vote on a Republican spending plan that would likely include cuts to Medicaid, the federal health insurance program for lower-income people.

Who could be impacted if GOP makes cuts to Medicaid funding?

UCLA Center for Health Policy Research Senior Fellow Mark A. Peterson said of possible Medicaid cuts: "If they were to try to fill in, they either have to raise taxes significantly, which is not likely to happen, or they would have to cut, say, their next major spending category, which is also not likely. And even very wealthy states, like California, for instance, have been going through their own budget struggles. So, it's not as though they're sitting on a pile of money that's ready to reallocate. There would be extremely serious budgetary consequences." News https://abcnews.go.com/Health/impacted-gop-makes-cuts-medicaid-funding/story?id=119203071
