  • Income-Based Inequalities in Health System Performance in the US and South Korea

    Open AccessSungchul Park, Karen Eggleston et al.ARTICLEJAMA Health Forum2026

    In this cross-sectional study, income was associated with disparities in health system performance in both the US and South Korea, with larger differences by income in the US. The findings suggest that structural and systemic policy efforts are needed to address income-based health inequalities, particularly in the US

  • Medicare Eligibility and Health Care Use Among Adults With Psychological Distress

    Open AccessSungchul Park, Katherine A Koh et al.ARTICLEJAMA Health Forum2025

    These findings suggest that Medicare eligibility at age 65 years was associated with decreased use of mental health outpatient services and increased acute care use among adults with psychological distress. These findings highlight the need for policies that address gaps in mental health care in the Medicare program

  • Health Care Spending Increases and Value in South Korea

    Open AccessSungchul Park, Joseph L Dieleman et al.ARTICLEJAMA Health Forum2025

    This cross-sectional study indicates that increased spending per person, which accounted for half of the total health care spending increase, was associated with improved overall health, evidenced by substantially fewer DALYs. These findings contribute to understanding and evaluating the value of health care spending in Korea

    Open AccessGiryeon Bae, Hansoo Ko et al.ARTICLEEconomics & Human Biology2025

  • Utilisation of in-person and telehealth care among US adults with loneliness and social isolation

    Sungchul Park, Jiani Yu et al.ARTICLEJournal of Epidemiology and…2025References: 17

    BACKGROUND: Telehealth has become a critical tool for improving access to care among populations facing physical barriers to in-person care. However, its potential role in delivering care to adults with social barriers remains underexplored. We examined whether adults with loneliness or social isolation are more likely to use telehealth care versus in-person care compared to adults without loneliness or social isolation. METHODS: This cross-secti…

    Sungchul Park, Stephen A BerkowitzARTICLEJournal of Epidemiology and…2025Cited by: 1References: 34

    BACKGROUND: Food insecurity poses a substantial threat to mental health. However, there is limited understanding of how food-insecure adults experience mental health challenges and access necessary health services. We examined the association of food insecurity with mental health status, mental health service utilisation and general healthcare utilisation among US adults. METHODS: A retrospective longitudinal cohort study was conducted to analyse…

  • Burden of disease scenarios for 204 countries and territories, 2022–2050

    Open AccessStein Emil Vollset, Hazim S Ababneh et al.ARTICLEThe Lancet2024

    BACKGROUND: Future trends in disease burden and drivers of health are of great interest to policy makers and the public at large. This information can be used for policy and long-term health investment, planning, and prioritisation. We have expanded and improved upon previous forecasts produced as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) and provide a reference forecast (the most likely future), and alternativ…

  • Global burden and strength of evidence for 88 risk factors in 204 countries and 811 subnational locations, 1990–2021

    Open AccessMichael Brauer, Gregory A Roth et al.ARTICLEThe Lancet2024

    BACKGROUND: Understanding the health consequences associated with exposure to risk factors is necessary to inform public health policy and practice. To systematically quantify the contributions of risk factor exposures to specific health outcomes, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 aims to provide comprehensive estimates of exposure levels, relative health risks, and attributable burden of disease for 88 ri…

  • Healthcare Expenditures Among Older Immigrants in the United States With Alzheimer’s Disease and Related Dementias

    Open AccessSeyeon Jang, Xuanzi Qin et al.ARTICLEThe Journals of Gerontology…2024References: 4

    Our results suggest potential shifts in costs resulting from delayed access to, and diagnosis or treatment of ADRD at a younger age, leading to increased healthcare needs and expenses among U.S. foreign-born older adults

  • Association of Medicare Advantage Star Ratings With Racial and Ethnic Disparities in Hospitalizations for Ambulatory Care Sensitive Conditions

    Sungchul Park, Rachel M Werner et al.ARTICLEMedical Care2022References: 38

    BACKGROUND: Enrollment in high-quality Medicare Advantage (MA) plans, measured by a 5-star quality rating system, was lower among racial and ethnic minority enrollees than White enrollees partly due to fewer high-quality plans available in their counties of residence. This may contribute to racial and ethnic disparities in ambulatory care sensitive condition (ACSC) hospitalizations. OBJECTIVE: We examined whether there were racial and ethnic disp…

  • Enrollment in Supplemental Insurance Coverage Among Medicare Beneficiaries by Race/Ethnicity

  • Trends in Self-reported Forgone Medical Care Among Medicare Beneficiaries During the Covid-19 Pandemic

    Open AccessSungchul Park, Jim P StimpsonARTICLEJAMA Health Forum2021

    The results of this cross-sectional survey study suggest that the COVID-19 pandemic may exacerbate existing barriers to care and lead Medicare beneficiaries to delay needed care. Policy makers must continue to identify effective means of meeting the forgone care backlog and maintaining continuity of care, especially for those with mental health problems

    Sungchul Park, Jie Chen et al.ARTICLEMedical Care2021References: 12

    BACKGROUND: Asian Americans have lower cancer screening rates than non-Latino "Whites," suggesting inequities in cancer prevention among Asian Americans. Little is known about inequities in cancer treatment between Whites and Asian Americans with cancer. METHODS: Using the 2002-2017 Medical Expenditure Panel Survey, we examined inequities in access to care and health care spending between Whites and Asian Americans with and without cancer. Our ou…

  • Racial Disparities in Avoidable Hospitalizations in Traditional Medicare and Medicare Advantage

    Sungchul Park, Paul Fishman et al.ARTICLEMedical Care2021References: 29

    IMPORTANCE: Compared with traditional Medicare (TM), Medicare Advantage (MA) has the potential to reduce racial disparities in hospitalizations for ambulatory care sensitive conditions (ACSC). As racial disparities may be partly attributable to unequal treatment based on where people live, this suggests the need of examining geographic variations in racial disparities. OBJECTIVE: The aim of this study was to examine differences in ACSC hospitaliz…

    Paul Fishman, Paul A Fishman et al.ARTICLEMedical Care2020References: 25

    BACKGROUND: Although one third of Medicare beneficiaries are enrolled in Medicare Advantage (MA) plans, there is limited information about the cost of treating Alzheimer disease and related dementias (ADRD) in these settings. OBJECTIVE: The objective of this study was to estimate direct health care costs attributable to ADRD among older adults within a large MA plan. RESEARCH DESIGN: A retrospective cohort design was used to estimate direct total…

    Sungchul Park, Eric B Larson et al.ARTICLEMedical Care2020References: 24

    OBJECTIVE: The objective of this study was to determine differences in health care utilization, process of diabetes care, care satisfaction, and health status for Medicare Advantage (MA) and traditional Medicare (TM) beneficiaries with and without diabetes. METHODS: Using the 2010-2016 Medicare Current Beneficiary Survey, we identified MA and TM beneficiaries with and without diabetes. To address the endogenous plan choice between MA and TM, we u…

  • Financial Performance of Medicare Advantage Contracts in 2014 and Plan Renewal, Consolidation, and Termination Rates in the Subsequent Year

    Brent A Langellier, Sungchul ParkARTICLEMedical Care2020References: 6

    BACKGROUND: Starting in 2014, the Affordable Care Act mandated that Medicare Advantage (MA) contracts spend at least 85% of total revenue on claims and quality improvement [ie, the medical loss ratio (MLR)] and submit revenue and cost data annually in MLR reports. These reports can improve transparency of the financial performance of MA contracts. However, little is known about revenues and costs of insurers that participate in MA and its impacts…

We estimated the unadjusted and a…
