Better Data to Improve Medicaid.

This JAMA Forum discusses the current data collection mechanisms used for Medicare and proposes ways to improve nationwide data collection efforts for Medicaid.

Disparities in Mistreatment During Childbirth.

Importance: Lack of respectful maternity care may be a key factor associated with disparities in maternal health. However, mistreatment during childbirth has not been widely documented in the US. Objectives: To estimate the prevalence of mistreatment by health care professionals during childbirth among a representative multistate sample and to identify patient characteristics associated with mistreatment experiences. Design, Setting, and Participants: This cross-sectional study used representative survey data collected from respondents to the 2020 Pregnancy Risk and Monitoring System in 6 states and New York City who had a live birth in 2020 and participated in the Postpartum Assessment of Health Survey at 12 to 14 months' post partum. Data were collected from January 1, 2021, to March 31, 2022. Exposures: Demographic, social, clinical, and birth characteristics that have been associated with patients' health care experiences. Main Outcomes and Measures: Any mistreatment during childbirth, as measured by the Mistreatment by Care Providers in Childbirth scale, a validated measure of self-reported experiences of 8 types of mistreatment. Survey-weighted rates of any mistreatment and each mistreatment indicator were estimated, and survey-weighted logistic regression models estimated odds ratios (ORs) and 95% CIs. Results: The sample included 4458 postpartum individuals representative of 552 045 people who had live births in 2020 in 7 jurisdictions. The mean (SD) age was 29.9 (5.7) years, 2556 (54.4%) identified as White, and 2836 (58.8%) were commercially insured. More than 1 in 8 individuals (13.4% [95% CI, 11.8%-15.1%]) reported experiencing mistreatment during childbirth. The most common type of mistreatment was being "ignored, refused request for help, or failed to respond in a timely manner" (7.6%; 95% CI, 6.5%-8.9%). Factors associated with experiencing mistreatment included being lesbian, gay, bisexual, transgender, queer identifying (unadjusted OR [UOR], 2.3; 95% CI, 1.4-3.8), Medicaid insured (UOR, 1.4; 95% CI, 1.1-1.8), unmarried (UOR, 0.8; 95% CI, 0.6-1.0), or obese before pregnancy (UOR, 1.3; 95% CI, 1.0-1.7); having an unplanned cesarean birth (UOR, 1.6; 95% CI, 1.2-2.2), a history of substance use disorder (UOR, 2.6; 95% CI, 1.3-5.1), experienced intimate partner or family violence (UOR, 2.3; 95% CI, 1.3-4.2), mood disorder (UOR, 1.5; 95% CI, 1.1-2.2), or giving birth during the COVID-19 public health emergency (UOR, 1.5; 95% CI, 1.1-2.0). Associations of mistreatment with race and ethnicity, age, educational level, rural or urban geography, immigration status, and household income were ambiguous. Conclusions and Relevance: This cross-sectional study of individuals who had a live birth in 2020 in 6 states and New York City found that mistreatment during childbirth was common. There is a need for patient-centered, multifaceted interventions to address structural health system factors associated with negative childbirth experiences.

The Effect of the Earned Income Tax Credit on Physical and Mental health-Results from the Atlanta Paycheck Plus Experiment.

Policy Points The Paycheck Plus randomized controlled trial tested a fourfold increase in the Earned Income Tax Credit (EITC) for single adults without dependent children over 3 years in New York and Atlanta. In New York, the intervention improved economic, mental, and physical health outcomes. In Atlanta, it had no economic benefit or impact on physical health and may have worsened mental health. In Atlanta, tax filing and bonus receipt were lower than in the New York arm of the trial, which may explain the lack of economic benefits. Lower mental health scores in the treatment group were driven by disadvantaged men, and the study sample was in good mental health. CONTEXT: The Paycheck Plus experiment examined the effects of an enhanced Earned Income Tax Credit (EITC) for single adults on economic and health outcomes in Atlanta, GA and New York City (NYC). The NYC study was completed two years prior to the Atlanta study and found mental and physical benefits for the subgroups that responded best to the economic incentives provided. In this article, we present the findings from the Atlanta study, in which the uptake of the treatment (tax filings and EITC bonus) were lower and economic and health benefits were not observed. METHODS: Paycheck Plus Atlanta was an unblinded randomized controlled trial that assigned n = 3,971 participants to either the standard federal EITC (control group) or an EITC supplement of up to $2,000 (treatment group) for three tax years (2017-2019). Administrative data on employment and earnings were obtained from the Georgia Department of Labor and survey data were used to examine validated measures of health and well-being. FINDINGS: In Atlanta, the treatment group had significantly higher earnings in the first project year but did not have significantly higher cumulative earnings than the control group overall (mean difference = $1,812, 95% CI = -150, 3,774, p = 0.07). The treatment group also had significantly lower scores on two measures of mental health after the intervention was complete: the Patient Health Questionnaire 8 (mean difference = 0.19, 95% CI = 0.06, 0.32, p = 0.005) and the Kessler 6 (mean difference = 0.15, 95% CI = 0.03, 0.27, p = 0.012). Secondary analyses suggested these results were driven by disadvantaged men, but the study sample was in good mental health. CONCLUSIONS: The EITC experiment in Atlanta was not associated with gains in earnings or improvements in physical or mental health.

Health Insurance Coverage and Access to Care by Sexual Orientation During the COVID-19 Pandemic: United States, January 2021-February 2022.

Objectives. To compare health insurance coverage and access to care by sex and sexual minority status during the COVID-19 pandemic and assess whether lack of insurance hindered access to care by sexual minority status. Methods. Using Behavioral Risk Factor Surveillance System data (January 2021-February 2022), we examined differences by sex and sexual orientation among 158 722 adults aged 18 to 64 years living in 34 states. Outcomes were health insurance coverage type and 3 access to care measures. Results. Sexual minority women were significantly more likely to be uninsured than were heterosexual women, and lack of insurance widened the magnitude of disparity by sexual minority status in all measures of access. Compared with heterosexual men with health insurance, sexual minority men with health insurance were significantly more likely to report being unable to afford necessary care. Conclusions. During the pandemic, 1 in 8 sexual minority adults living in 34 study states were uninsured. Among sexual minority women, lack of insurance widened inequities in access to care. There were inequities among sexual minority men with health insurance. Public Health Implications. Sexual minority adults may be disproportionately affected by the unwinding of the COVID-19 public health emergency and may require tailored efforts to mitigate insurance coverage loss.

The Health And Social Needs Of Medicaid Beneficiaries In The Postpartum Year: Evidence From A Multistate Survey.

As of September 2023, thirty-seven states and Washington, D.C., had adopted the option in the American Rescue Plan Act of 2021 to extend pregnancy Medicaid eligibility to one year postpartum. To inform state initiatives to support this newly covered population, we conducted a representative survey of postpartum people in six states and New York City from January 2021 to March 2022. Compared with respondents who had commercial insurance at the time of childbirth, Medicaid respondents were less likely to have a usual source of care and reported less use of primary, specialty, and dental care in the postpartum year. Depression symptoms and social concerns such as food insecurity, intimate partner violence, and financial strain were significantly higher in the Medicaid population. Rates of anxiety symptoms, delaying or not getting needed care, and unsatisfactory child care were similar in both populations. Our findings suggest that postpartum Medicaid extensions should be coupled with state initiatives to address beneficiaries' health and social needs. National investments in data collection on postpartum people will be critical to support evidence-based policy making to improve maternal health and well-being.

Association of Affordable Care Act Medicaid Expansions with Births Among Low-Income Women of Reproductive Age.

Background: This study examined the association between Medicaid expansions under the Affordable Care Act (ACA) and births among low-income women of reproductive age in the United States. Materials and Methods: We used data from the 2008 to 2019 American Community Survey to estimate the association between state adoption of Medicaid expansion under the ACA and the percent of low-income women of reproductive age with a birth in the past year using a difference-in-difference research design. Subgroup analysis was explored by race and ethnicity, age group, educational attainment, marital status, and number of children. Results: We found that Medicaid expansion was associated with a small reduction in births among low-income women of reproductive age by 0.45 percentage points (95% confidence interval: -0.84 to -0.05). In subgroup analyses, we found reductions in births among Hispanic women, American Indian or Alaska Native women, women 25-29 years of age, women 35-39 years of age, unmarried women, and women with more than three children. Conclusions: Reductions in births associated with Medicaid expansion could suggest that expanding Medicaid addressed previously unmet reproductive health care needs among low-income women of reproductive age. The reductions in births among low-income women that we observe were occurring among some groups with higher unintended pregnancy rates, including Hispanic women, American Indian or Alaska Native women, young women, and unmarried women. These findings underscore the importance of reproductive health care access through insurance coverage on empowering women to have control over their reproductive decision-making and timing.

Differences in Diabetic Prescription Drug Utilization and Costs Among Patients With Diabetes Enrolled in Colorado Marketplace and Medicaid Plans, 2014-2015.

Importance: Increasing prices of antidiabetic medications in the US have raised substantial concerns about the effects of drug affordability on diabetes care. There has been little rigorous evidence comparing the experiences of patients with diabetes across different types of insurance coverage. Objective: To compare the utilization patterns and costs of prescription drugs to treat diabetes among low-income adults with Medicaid vs those with Marketplace insurance in Colorado during 2014 and 2015. Design, Setting, and Participants: This cross-sectional study included diabetic patients enrolled in Colorado Medicaid and Marketplace plans who were aged 19 to 64 years and had incomes between 75% and 200% of the federal poverty level during 2014 and 2015. Data analysis was conducted from September 2020 to April 2021. Exposures: Health insurance through Colorado Medicaid or Colorado's state-based Marketplace. Main Outcomes and Measures: Primary outcomes were drug utilization (prescription drug fills) and drug costs (total costs and out-of-pocket costs). The secondary outcome was months with an active prescription for noninsulin antidiabetic medications. An all payer claims database was combined with income data, and linear models were used to adjust for clinical and demographic confounders. Results: Of 22 788 diabetic patients included in the study, 20 245 were enrolled in Medicaid and 2543 in a Marketplace plan. Marketplace-eligible individuals were older (mean [SD] age, 52.12 [10.60] vs 47.70 [11.33] years), and Medicaid-eligible individuals were more likely to be female (12 429 [61.4%] vs 1413 [55.6%]). Medicaid-eligible patients were significantly more likely than Marketplace-eligible patients to fill prescriptions for dipeptidyl peptidase 4 inhibitors (adjusted difference, -3.7%; 95% CI, -5.3 to -2.1; P < .001) and sulfonylureas (adjusted difference, -6.6%; 95% CI, -8.9 to -4.3; P < .001). Overall rates of insulin use were similar in the 2 groups (adjusted difference, -2.3%; -5.1 to 0.5; P = .11). Out-of-pocket costs for noninsulin medications were 84.4% to 95.2% lower and total costs were 9.4% to 54.2% lower in Medicaid than in Marketplace plans. Out-of-pocket costs for insulin were 76.7% to 94.7% lower in Medicaid than in Marketplace plans, whereas differences in total insulin costs were mixed. The percentage of months of apparent active medication coverage was similar between the 2 groups for 4 of 5 drug classes examined, with Marketplace-eligible patients having a greater percentage of months than Medicaid-eligible patients for sulfonylureas (adjusted difference, 5.3%; 95% CI, 0.3%-10.4%; P = .04). Conclusions and Relevance: In this cross-sectional study, drug utilization across multiple drug classes was higher and drug costs were significantly lower for adults with diabetes enrolled in Medicaid than for those with subsidized Marketplace plans. Patients with Marketplace coverage had a similar percentage of months with an active prescription as patients with Medicaid coverage.

Effect of Expanding the Earned Income Tax Credit to Americans Without Dependent Children on Psychological Distress.

Antipoverty policies have the potential to improve mental health. We conducted a randomized trial (Paycheck Plus Health Study Randomized Controlled Trial, New York, New York) to investigate whether a 4-fold increase in the Earned Income Tax Credit for low-income Americans without dependent children would reduce psychological distress relative to the current federal credit. Between 2013 and 2014, a total of 5,968 participants were recruited; 2,997 were randomly assigned to the treatment group and 2,971 were assigned to the control group. Survey data were collected 32 months postrandomization (n = 4,749). Eligibility for the program increased employment by 1.9 percentage points and after-bonus earnings by 6% ($635/year), on average, over the 3 years of the study. Treatment was associated with a marginally statistically significant decline in psychological distress, as measured by the 6-item Kessler Psychological Distress Scale, relative to the control group (score change = -0.30 points, 95% confidence interval (CI): -0.63, 0.03; P = 0.072). Women in the treated group experienced a half-point reduction in psychological distress (score change = -0.55 points, 95% CI: -0.97, -0.13; P = 0.032), and noncustodial parents had a 1.36-point reduction (95% CI: -2.24, -0.49; P = 0.011). Expansion of a large antipoverty program to individuals without dependent children reduced psychological distress for women and noncustodial parents-the groups that benefitted the most in terms of increased after-bonus earnings.

Work-related and personal predictors of COVID-19 transmission: evidence from the UK and USA.

OBJECTIVE: To develop evidence of work-related and personal predictors of COVID-19 transmission. SETTING AND RESPONDENTS: Data are drawn from a population survey of individuals in the USA and UK conducted in June 2020. BACKGROUND METHODS: Regression models are estimated for 1467 individuals in which reported evidence of infection depends on work-related factors as well as a variety of personal controls. RESULTS: The following themes emerge from the analysis. First, a range of work-related factors are significant sources of variation in COVID-19 infection as indicated by self-reports of medical diagnosis or symptoms. This includes evidence about workplace types, consultation about safety and union membership. The partial effect of transport-related employment in regression models makes the chance of infection over three times more likely while in univariate analyses, transport-related work increases the risk of infection by over 40 times in the USA. Second, there is evidence that some home-related factors are significant predictors of infection, most notably the sharing of accommodation or a kitchen. Third, there is some evidence that behavioural factors and personal traits (including risk preference, extraversion and height) are also important. CONCLUSIONS: The paper concludes that predictors of transmission relate to work, transport, home and personal factors. Transport-related work settings are by far the greatest source of risk and so should be a focus of prevention policies. In addition, surveys of the sort developed in this paper are an important source of information on transmission pathways within the community.

Association of Medicaid vs Marketplace Eligibility on Maternal Coverage and Access With Prenatal and Postpartum Care.

Importance: Policy makers are considering insurance expansions to improve maternal health. The tradeoffs between expanding Medicaid or subsidized private insurance for maternal coverage and care are unknown. Objective: To compare maternal coverage and care by Medicaid vs marketplace eligibility. Design, Setting, and Participants: A retrospective cohort study using a difference-in-difference research design was conducted from March 14, 2020, to April 22, 2021. Maternal coverage and care use were compared among women with family incomes 100% to 138% of the federal poverty level (FPL) residing in 10 Medicaid expansion sites (exposure group) who gained Medicaid eligibility under the Affordable Care Act and in 5 nonexpansion sites (comparison group) who gained marketplace eligibility before (2011-2013) and after (2015-2018) insurance expansion implementation. Participants included women aged 18 years or older from the 2011-2018 Pregnancy Risk Assessment Monitoring System survey. Exposures: Eligibility for Medicaid or marketplace coverage under the Affordable Care Act. Main Outcomes and Measures: Outcomes included coverage in the preconception and postpartum periods, early and adequate prenatal care, and postpartum checkups and effective contraceptive use. Results: The study population included 11 432 women age 18 years and older (32% age 18-24 years, 33% age 25-29 years, 35% age ≥30 years) with incomes 100% to 138% FPL: 7586 in a Medicaid state (exposure group) and 3846 in a nonexpansion marketplace state (comparison group). Women in marketplace states were younger, had higher educational level and marriage rates, and had less racial and ethnic diversity. Medicaid relative to marketplace eligibility was associated with increased Medicaid coverage (20.3 percentage points; 95% CI, 12.8 to 30.0 percentage points), decreased private insurance coverage (-10.8 percentage points; 95% CI, -13.3 to -7.5 percentage points), and decreased uninsurance (-8.7 percentage points; 95% CI, -20.1 to -0.1 percentage points) in the preconception period, increased postpartum Medicaid (17.4 percentage points; 95% CI, 1.7 to 34.3 percentage points) and increased adequate prenatal care (4.4 percentage points; 95% CI, 0.1 to 11.0 percentage points) in difference-in-difference models. No evidence of significant differences in early prenatal care, postpartum check-ups, or postpartum contraception was identified. Conclusions and Relevance: In this cohort study, eligibility for Medicaid was associated with increased Medicaid, lower preconception uninsurance, and increased adequate prenatal care use. The lower rates of preconception uninsurance among Medicaid-eligible women suggest that women with low incomes were facing barriers to marketplace enrollment, underscoring the potential importance of reducing financial barriers for the population with low incomes.

Extending Postpartum Medicaid: State and Federal Policy Options during and after COVID-19.

The United States is facing a maternal health crisis with rising rates of maternal mortality and morbidity and stark disparities in maternal outcomes by race and socioeconomic status. Among the efforts to address this issue, one policy proposal is gaining particular traction: extending the period of Medicaid eligibility for pregnant women beyond 60 days after childbirth. The authors examine the legislative and regulatory pathways most readily available for extending postpartum Medicaid, including their relative political, economic, and public health trade-offs. They also review the state and federal policy activity to date and discuss the impact of the COVID-19 pandemic on the prospects for policy change.

A longitudinal analysis of violence and healthcare service utilization in Mexico.

OBJECTIVES: We analyze the degree to which community violence in Mexico, largely due to organized crime violence, affects health care service utilization. METHODS: This study exploits temporal and geographic variation in monthly county-level homicide rates, matching outpatient service utilization from individual longitudinal measures. Sensitivity analyses test for an age specific concentration of violence, respiratory conditions that are likely unrelated to violence, insurance status and health center availability per capita. We test for distributional responses to violence by urban and rural localities. RESULTS: The likelihood of service utilization increases by 5.2% with each additional homicide per 100,000. When we include self-reported health conditions in the model, our main coefficient remains significant at 4.5%. We find no added effect to our results from interaction terms for age specific concentration of violence, respiratory conditions, insurance status, or health center availability. A substantial increase of 11.7% in the likelihood of service utilization occurs in localities with > = 100,000 inhabitants, suggesting that service utilization is sensitive to the location of violence. CONCLUSIONS: Results highlight the relationship between and increase in violence at the local level and an increase in health care service utilization. This study is among the first to examine this relationship empirically in Mexico. Future research is needed to shed more light on this relationship and its mechanisms.

Comparison of Utilization, Costs, and Quality of Medicaid vs Subsidized Private Health Insurance for Low-Income Adults.

Importance: There has been little rigorous evidence to date comparing public vs private health insurance. With policy makers considering a range of policies to expand coverage, understanding the trade-offs between these coverage types is critical. Objective: To compare months of coverage, utilization, quality, and costs between low-income adults with Medicaid vs those with subsidized private (Marketplace) insurance. Design, Setting, and Participants: This cross-sectional study used a propensity score-matched sample of adults enrolled in either Medicaid or Marketplace plans at any point between January 1, 2014, and December 31, 2015. The sample was restricted to individuals with incomes narrowly above and below 138% of the federal poverty level (FPL), which represented the eligibility cutoff between the programs. Data were obtained from 3 state agencies merging comprehensive insurance claims with income eligibility data for Colorado Medicaid expansion and Marketplace enrollees. Income data were linked with an all-payer claims database, and generalized linear models were used to adjust for clinical and demographic confounders. Participants included 8182 low-income nonpregnant adults aged 19 to 64 years enrolled in Medicaid or Marketplace coverage during the 2014 to 2015 period, with incomes between 134% and 143% of the FPL. Exposures: Health insurance through Colorado Medicaid or Colorado's state-based Marketplace. Main Outcomes and Measures: The primary analytical approach was a multivariate regression analysis of the propensity score-matched sample. Primary outcomes were months of coverage in Medicaid or Marketplace insurance, office and emergency department (ED) visits, ambulatory care-sensitive hospitalizations, and total costs. For secondary quality outcomes, the propensity score-matched sample was widened to 129% to 148% of the FPL to ensure adequate sample size. Secondary outcomes included prescription drug utilization, types of ED visits, hospitalizations, out-of-pocket costs, and clinical quality measures. Primary data analysis was between September 2018 to July 2019, with revisions finalized in November 2020. Results: The propensity score-matched narrow-income sample included a total of 8182 participants (4091 Medicaid eligible [50%]: mean [SD] age, 42.8 [13.6] years; 2230 women [54.5%]; 4091 Marketplace eligible [50%]: mean [SD] age, 42.7 [13.9] years; 2229 women [54.5%]). Demographic differences across the 2 groups were well balanced, with all standardized mean differences less than 0.10. Marketplace coverage was associated with fewer ED visits (mean, 0.36 [95% CI, 0.32-0.40] visits vs 0.56 [95% CI, 0.50-0.62] visits; P < .001) and more office (outpatient) visits than Medicaid (mean, 2.22 [95% CI, 2.11-2.32] visits vs 1.73 [95% CI, 1.64-1.81] visits; P < .001). No differences in ambulatory care-sensitive hospitalizations were found (0.004 [95% CI, 0.001-0.006] vs 0.007 [95% CI, 0.002-0.011]; P = .15). Total costs were 83% higher in Marketplace coverage (mean, $4553 [95% CI, $3368-$5738] vs $2484 [95% CI, $1760-$3209]; P < .001) owing almost entirely to higher prices, and out-of-pocket costs were 10 times higher (mean, $569 [95% CI, $337-$801] vs $45 [95% CI, $26-$65]; P < .001). Five of 12 secondary quality measures favored private insurance, and 1 favored Medicaid. Conclusions and Relevance: In this cross-sectional propensity score-matched study, Medicaid and Marketplace coverage differed in important ways. Public coverage through Medicaid was associated with more ED visits and fewer office visits than private Marketplace coverage, which may reflect barriers to outpatient care or lower cost-sharing barriers to ED care in Medicaid. Results suggest that Medicaid coverage was substantially less costly to beneficiaries and society than private coverage, with mixed results on health care quality.

Comparison of Income Eligibility for Medicaid vs Marketplace Coverage for Insurance Enrollment Among Low-Income US Adults.

Importance: The Affordable Care Act created 2 new coverage options for uninsured adults: Medicaid expansion, which in most states provides comprehensive coverage without premiums and deductibles; and private marketplace coverage, which requires a premium contribution and cost-sharing, though with generous federal subsidies at lower incomes. How enrollment rates compare in the marketplace vs Medicaid is an important policy question as states continue to weigh alternative coverage options such as Medicaid buy-in programs, enrolling Medicaid-eligible populations into marketplace plans, or creating a public option. Objective: To assess the association between income eligibility for Medicaid vs marketplace coverage and insurance enrollment among low-income adults in Colorado. Design Setting and Participants: Using 2014 and 2015 all-payer claims data from Colorado and detailed income eligibility information, we used a regression discontinuity design to assess the difference in Medicaid and marketplace enrollment just below and just above 138% of the federal poverty level (FPL), the eligibility threshold between the 2 programs. The sample included nonpregnant adults aged 19 to 64 years with incomes between 75% to 400% FPL. We stratified our analysis by age, sex, chronic condition status, and urban vs rural residence. Analysis was conducted from January to October 2020. Main Outcome and Measures: The main outcome was total enrollment in either Medicaid or marketplace coverage during marketplace's Open Enrollment period. Income-based health insurance eligibility was assessed as a percentage of FPL at the time of initial application for coverage. Results: The primary analytical sample included 32 091 enrollees in 2014 and 55 451 in 2015, with incomes ranging from 120% to 156% FPL. Most enrollees were women (59.26% in 2014, 59.20% in 2015), resided in urban areas (70.36% in 2014, 73.08% in 2015), and had no chronic conditions (74.66% in 2014, 76.11% in 2015). For age, in 2014 and 2015, respectively, 13.22% and 13.93% were aged 19 to 25 years, 27.85% and 28.54% were aged 26 to 34 years, 23.58% and 24.34% were aged 35 to 44 years, 18.35% and 17.75% were aged 45 to 54 years, and 17.00% and 15.44% were aged 55 to 64 years. Marketplace enrollment was 81.3% (95% CI, -86.0% to -75.0%) lower than Medicaid enrollment in 2014 and 88.6% (95% CI, -90.8% to -86.0%) lower in 2015 among those close to the 138% FPL eligibility threshold. The drop-off in marketplace enrollment was largest among younger adults, aged 26 to 34 and 35 to 44 years: relative drop off -88.7% (95% CI, -93.3% to -80.8%) and -87.8% (95% CI, -90.8% to -83.9%) in 2014, and relative drop off -91.9% (95% CI, -94.5% to -87.9%) and -93.0% (95% CI, -94.5% to -91.1%) in 2015, respectively. Conclusions and Relevance: In this cross-sectional study using a regression-discontinuity analysis, meaningful gaps in insurance enrollment may have existed for those with incomes just above the eligibility threshold for Medicaid expansion, especially among younger adults. Policies expanding Medicaid income eligibility or zero-dollar premium marketplace plans are likely to be more effective at inducing enrollment than subsidized private plans with premium requirements.

The Health Effects Of Expanding The Earned Income Tax Credit: Results From New York City.

Antipoverty policies may hold promise as tools to improve health and reduce mortality rates among low-income Americans. We examined the health effects of the New York City Paycheck Plus randomized controlled trial. Paycheck Plus tests the impact of a potential fourfold increase in the Earned Income Tax Credit for low-income Americans without dependent children. Starting in 2015, Paycheck Plus offered 5,968 study participants a credit of up to $2,000 at tax time (treatment) or the standard credit of about $500 (control). Health-related quality of life and other outcomes for a representative subset of these participants (n = 3,289) were compared to those of a control group thirty-two months after randomization. The intervention had a modest positive effect on employment and earnings, particularly among women. It had no effect on health-related quality of life for the overall sample, but women realized significant improvements.
