Objective: We studied patterns in health care access between Latino and non-Latino White adults according to citizenship status before and after the American Rescue Plan Act (ARPA) of 2021 was enacted to determine whether inequities changed.

Methods: This study used 2019-2022 National Health Survey Interview data. Differences in predicted probabilities from logistic regression models were used to estimate changes in health care access outcomes (any insurance coverage, private insurance coverage, delaying care due to cost, and having a usual source of care) among Latino citizens, Latino noncitizens, and non-Latino White citizens in periods before and after ARPA's enactment (2019-2020 vs 2021-2022).

Article Synopsis
  • Community Health Centers (CHCs) provide essential healthcare and support services to underserved populations, aiming to improve access and reduce health disparities, particularly for patients with cardiometabolic risk factors.
  • A study analyzed data from the 2014 Health Center Patient Survey involving 2,358 adult patients with such risk factors to investigate how enabling services (non-clinical support) affected healthcare access and usage patterns.
  • Results showed that users of enabling services were significantly less likely to delay or forgo care and more likely to attend routine check-ups, but interestingly, those with multiple risk factors experienced increased emergency room visits, raising questions about the overall impact of these services on healthcare behaviors.

Article Synopsis
  • The study investigates the link between socioeconomic status (SES) and outcomes after lower extremity arterial reconstruction for severe peripheral arterial disease (PAD).
  • Data from over 131,000 patients showed that those in the lowest median household income quartile had higher rates of amputations and readmissions compared to those in the highest quartile.
  • The findings suggest that lower SES is tied to poorer surgical outcomes, highlighting the need for addressing these socioeconomic disparities to improve patient care.

The aim was to examine differences in health care access at the intersections of urbanicity and sexual identity in California. We used the 2014-2017 Adult California Health Interview Survey paired with the sexual orientation special use research file to create dummy groups representing each dimension of urbanicity and sexual identity to compare access to health care outcomes. We calculated unadjusted proportions and estimated adjusted odds ratios of each dimension relative to urban heterosexual people using logistic regressions.

Immigrants living in the United States experience disparities in satisfaction with medical care. Practicing patient-centered communication and providing racially (or race-concordant) concordant care are suggested as effective approaches to improve care satisfaction. Using the Medical Expenditure Panel Survey, we found that immigrant patients with medical providers who practiced patient-centered communication were more likely to be satisfied with the care they received regardless of patient-provider racial concordance, and that simply having racially concordant medical providers did not significantly affect the satisfaction level for immigrant patients.

Using a nationally representative sample from the 2013 to 2016 Medical Expenditure Panel Survey, we examined differences among non-Latino Whites and Asian subgroups (Asian Indians, Chinese, Filipinos, and other Asians) across distributions of total health care expenditures and out-of-pocket (OOP) expenditures. For total health care expenditures, differences between Asian and White adults persisted throughout the distribution, but the magnitude of the difference was larger at no or low levels of expenditures than at high expenditure levels. A similar pattern was observed in OOP expenditures, but the magnitude of the difference was substantially larger at low levels of expenditures.
