Insurance Coverage and Provision of Opioid Disorder Treatment
Open AccessDenis Agniel, Jonathan Cantor et al.ARTICLEJournal of Policy Analysis and…2026
Older adult opioid overdose deaths have increased over the past two decades in the United States. Methadone, one of three medications approved for opioid use disorder (OUD) treatment, was not covered by Medicare—the primary insurer of Americans 65 years and older—for OUD until 2020. We study the response of opioid treatment programs (OTPs), the only healthcare providers that can dispense methadone for the treatment of OUD in the United States, to…
Health System Expansion and Changes in Medicare Beneficiary Utilization of Safety Net Providers
Kun Li, José J Escarce et al.ARTICLEMedical Care2025References: 18
BACKGROUND: Evidence is limited on insured patients' use of safety net providers as vertically integrated health systems spread throughout the United States. OBJECTIVES: To examine whether market-level health system penetration is associated with: (1) switches in Medicare beneficiaries' usual source of primary care from federally qualified health centers (FQHCs) to health systems; and (2) FQHCs' overall Medicare patient and visit volume. RESEARCH…
Do Hospital Characteristics Predict Racial-and-Ethnic Disparities in Patient Experience? National Results From the HCAHPS Survey
Megan K Beckett, Marc N Elliott et al.ARTICLEMedical Care2024References: 27
OBJECTIVE: Assess whether hospital characteristics associated with better patient experiences overall are also associated with smaller racial-and-ethnic disparities in inpatient experience. BACKGROUND: Hospitals that are smaller, non-profit, and serve high proportions of White patients tend to be high-performing overall, but it is not known whether these hospitals also have smaller racial-and-ethnic disparities in care. RESEARCH DESIGN: We used l…
Measuring Equity in the Hospital Setting
Megan K Beckett, Katrin Hambarsoomian et al.ARTICLEMedical Care2023References: 20
BACKGROUND: Health care quality varies by patient factors, including race-and-ethnicity and preferred language. Addressing inequities requires identifying them and incentivizing equity. OBJECTIVES: We apply an approach first implemented in the Medicare Advantage setting to measure equity in patient experiences by race-and-ethnicity [Asian American and Native Hawaiian or Pacific Islander (AA and NHPI), Black, Hispanic, vs. White] and language pref…
Is Bigger Better
Tisamarie B Sherry, Cheryl L Damberg et al.ARTICLEMedical Care2022References: 19
BACKGROUND: Research on US health systems has focused on large systems with at least 50 physicians. Little is known about small systems. OBJECTIVES: Compare the characteristics, quality, and costs of care between small and large health systems. RESEARCH DESIGN: Retrospective, repeated cross-sectional analysis. SUBJECTS: Between 468 and 479 large health systems, and between 608 and 641 small systems serving fee-for-service Medicare beneficiaries, …
Measuring Inconsistency in Quality Across Patient Groups to Target Quality Improvement
Denis Agniel, Steven C Martino et al.ARTICLEMedical Care2022References: 7
BACKGROUND: Quality improvement (QI) may be aimed at improving care for all patients, or it may be targeted at only certain patient groups. Health care providers have little guidance when determining when targeted QI may be preferred. OBJECTIVES: The aim was to develop a method for quantifying performance inconsistency and guidelines for when inconsistency indicates targeted QI, which we apply to the performance of health plans for different pati…
Rates of Disenrollment From Medicare Advantage Plans Are Higher for Racial/Ethnic Minority Beneficiaries
Steven C Martino, Megan Mathews et al.ARTICLEMedical Care2021References: 26
BACKGROUND: Each year, about 10% of Medicare Advantage (MA) enrollees voluntarily switch to another MA contract, while another 2% voluntarily switch from MA to fee-for-service Medicare. Voluntary disenrollment from MA plans is related to beneficiaries' negative experiences with their plan, disrupts the continuity of care, and conflicts with goals to reduce Medicare costs. Little is known about racial/ethnic disparities in voluntary disenrollment …
Identifying as American Indian/Alaska Native in Urban Areas
Open AccessRyan Brown, D L Dickerson et al.ARTICLEYouth & Society2021Cited by: 6References: 57
American Indian and Alaska Native (AI/AN) youth exhibit multiple health disparities, including high rates of alcohol and other drug (AOD) use, violence and delinquency, and mental health problems. Approximately 70% of AI/AN youth reside in urban areas, where negative outcomes on behavioral health and well-being are often high. Identity development may be particularly complex in urban settings, where youth may face more fragmented and lower densit…

Provision of Social Services and Health Care Quality in US Community Health Centers, 2017
Ashley M Kranz, Ammarah Mahmud et al.ARTICLEAmerican Journal of Public Health2020References: 16
Objectives. To describe the types of social services provided at community health centers (CHCs), characteristics of CHCs providing these services, and the association between on-site provision and health care quality. Methods. We surveyed CHCs in 12 US states and the District of Columbia during summer 2017 (n = 208) to identify referral to and provision of services to address 8 social needs. Regression models estimated factors associated with th…
Real-Time Crime Centers in Chicago
John S Hollywood, John Hollywood et al.BOOK2019
The Chicago Police Department's Strategic Decision Support Centers (SDSCs) serve as command, control, and communications hubs for staff to gain awareness of what is happening in their districts and decide on responses. In this report, the authors evaluate the processes, organizational structures, and technologies employed in the SDSCs. They also assess the extent to which the introduction of SDSCs was associated with reductions in crime levels
Using Ancillary Sociodemographic Data to Identify Sexual Minority Adults Among Those Responding “Something Else” or “Don’t Know” to Sexual Orientation Questions
Marc N Elliott, James M Dahlhamer et al.ARTICLEMedical Care2019References: 20
BACKGROUND: General population surveys are increasingly offering broader response options for questions on sexual orientation-for example, not only gay or lesbian, but also "something else" (SE) and "don't know" (DK). However, these additional response options are potentially confusing for those who may not know what the terms mean. Researchers studying sexual orientation-based disparities face difficult methodological trade-offs regarding how be…
Unveiling an ‘invisible population
Elizabeth J D’amico, D L Dickerson et al.ARTICLEEthnicity and Health2019Cited by: 10References: 10
Objectives: There are limited public health data on urban American Indian/Alaska Native (AI/AN) populations, particularly adolescents. The current study attempted to address gaps by providing descriptive information on experiences of urban AI/AN adolescents across northern, central, and southern California. Design: We describe demographics and several behavioral health and cultural domains, including: alcohol and other drug (AOD) use, risky sexua…
