Background: Social determinants of health (SDOH) are associated with cardiovascular disease, but little is known about mechanisms underlying those relationships. We hypothesized that SDOH would be associated with uncontrolled hypertension (HTN) in adults with Medicaid. Methods: This was a retrospective analysis of adults in a Medicaid accountable care organization who had HTN diagnoses, received regular care at community health centers, and enrolled in a cohort study between December 2019 and December 2020. Baseline surveys collected demographics and SDOH, including food insecurity, unstable housing, cost-related medication underuse, and financial stress. Blood pressure (BP) measurements over 12 months after survey completion were obtained from the electronic health record. Participants were categorized as: uncontrolled HTN (mean systolic BP = 140 mm Hg and/or mean diastolic BP = 90 mm Hg), controlled HTN, or unknown HTN control (no BP documented). We examined the association of individual and cumulative (count, 0-4) SDOH with uncontrolled HTN and unknown HTN control using multivariable logistic regression adjusting for demographics, smoking, diabetes, and HTN medication. Results: Participants (n = 245) were mean (SD) age 51.3 (8.6) years, 66.1% female, 43.7% Hispanic, 34.3% White, and 18.0% Black. Overall, 58.0% had food insecurity, 38.0% had unstable housing, 29.4% had financial stress, and 20.0% reported cost-related medication underuse. BP was documented for 180 participants; 44 (24.4%) had uncontrolled HTN. In multivariable models, neither individual nor cumulative SDOH were associated with uncontrolled HTN or unknown HTN control. Conclusions: In a Medicaid-insured population receiving care at community health centers, adverse SDOH were prevalent but were not associated with HTN control. [ABSTRACT FROM AUTHOR]

The tax penalty for noncompliance with the Affordable Care Act's individual mandate is to be eliminated starting in 2019. We investigated the potential impact of this change on enrollees' decisions to purchase insurance and on individual-market premiums. In a survey of enrollees in the individual market in California in 2017, 19 percent reported that they would not have purchased insurance had there been no penalty. We estimated that premiums would increase by 4-7 percent if these enrollees were not in the risk pool. The percentages of enrollees who would forgo insurance were higher among those vdth lower income and education, Hispanics, and those who had been uninsured in the prior year, relative to the comparison groups. Compared to older enrollees and those with two or more chronic conditions, respectively, younger enrollees and those with no chronic conditions were also more likely to say that they would not have purchased insurance. Eliminating the mandate penalty alone is unlikely to destabilize the California individual market but could erode coverage gains, especially among groups whose members have historically been less likely to be insured.

Objectives: To study the impact of eliminating cost sharing for screening mammography on mammography rates in a large Medicare Advantage (MA) health plan which in 2010 eliminated cost sharing in anticipation of the Affordable Care Act mandate.Study Setting: Large MA health maintenance organization offering individual-subscriber MA insurance and employer-supplemented group MA insurance.Study Design: We investigated the impact on breast cancer screening of a policy that eliminated a $20 copayment for screening mammography in 2010 among 53,188 women continuously enrolled from 2007 to 2012 in an individual-subscriber MA plan, compared with 42,473 women with employer-supplemented group MA insurance in the same health maintenance organization who had full screening coverage during this period. We used differences-in-differences analysis to study the impact of cost-sharing elimination on mammography rates.Principal Findings: Annual screening rates declined over time for both groups, with similar trends pre-2010 and a slower decline after 2010 among women whose copayments were eliminated. Among women aged 65-74 years in the individual-subscriber MA plan, 44.9 percent received screening in 2009 compared with 40.9 percent in 2012, while 49.5 percent of women in the employer-supplemented MA plan received screening in 2009 compared with 44.1 percent in 2012, that is, a difference-in-difference effect of 1.4 percentage points less decline in screening among women experiencing the cost-sharing elimination. Effects were concentrated among women without recent screening. There were no differences by neighborhood socioeconomic status or race/ethnicity.Conclusions: Eliminating cost sharing for screening mammography was associated with modesty lower decline in screening rates among women with previously low screening adherence.
