Impact of state Medicaid expansion on cross-sector health and social service networks: Evidence from a longitudinal cohort study.

To examine the impact of state Medicaid expansion on the delivery of population health activities in cross-sector health and social services networks. Community networks are multisector, interorganizational networks that provide services ranging from the direct provision of individual social services to the implementation of population-level initiatives addressing community outcomes. We used data measuring the composition of cross-sector population health networks 2006-2018 National Longitudinal Survey of Public Health Systems (NALSYS) linked with the Area Health Resource File. A difference-in-differences approach was used to examine the impact of expansion on organization engagement in population health activities and network structure. Stratified random sampling of local public health jurisdictions in the United States. We restricted our data to jurisdictions serving populations of 100,000 or more and states that had NALSYS observations across all time periods, resulting in a final sample size of 667. Results from our adjusted difference-in-differences estimates indicated that Medicaid expansion was associated with a 2.3 percentage point increase in the density of population health networks (p < 0.10). Communities in states that expanded Medicaid experienced significant increases in the participation of local public health, local government, hospital, nonprofit, insurer, and K-12 schools. Of the organizations with significant increases in expansion communities, nonprofits (7.7 percentage points, p < 0.01), local public health agencies (6.5 percentage points, p < 0.01), hospitals (5.8 percentage points, p < 0.01), and local government agencies (6.0 percentage points, p < 0.05) had the largest gains. Our study found increases in cross-sector participation in population health networks in states that expanded Medicaid compared with nonexpansion states, suggesting that additional coverage gains are associated with positive changes in population health network structure.

The association of Medicaid expansion and pediatric cancer overall survival.

Medicaid eligibility expansion, though not directly applicable to children, has been associated with improved access to care in children with cancer, but associations with overall survival are unknown. Data for children ages 0 to 14 years diagnosed with cancer from 2011 to 2018 were queried from central cancer registries data covering cancer diagnoses from 40 states as part of the Centers for Disease Control and Prevention's National Program of Cancer Registries. Difference-in-differences analyses were used to compare changes in 2-year survival from 2011-2013 to 2015-2018 in Medicaid expansion relative to nonexpansion states. In adjusted analyses, there was a 1.50 percentage point (95% confidence interval = 0.37 to 2.64) increase in 2-year overall survival after 2014 in expansion relative to nonexpansion states, particularly for those living in the lowest county income quartile (difference-in-differences = 5.12 percentage point, 95% confidence interval = 2.59 to 7.65). Medicaid expansion may improve cancer outcomes for children with cancer.

Association of Medicaid expansion and 1115 waivers for substance use disorders with hospital provision of opioid use disorder services: a cross sectional study

IntroductionOpioid-related hospitalizations have risen dramatically, placing hospitals at the frontlines of the opioid epidemic. Medicaid expansion and 1115 waivers for substance use disorders (SUDs) are two key policies aimed at expanding access to care, including opioid use disorder (OUD) services. Yet, little is known about the relationship between these policies and the availability of hospital based OUD programs. The aim of this study is to determine whether state Medicaid expansion and adoption of 1115 waivers for SUDs are associated with hospital provision of OUD programs.MethodsWe conducted a cross-sectional study of a random sample of hospitals (n = 457) from the American Hospital Association’s 2015 American Hospital Directory, compiled with the most recent publicly available community health needs assessment (2015–2018).ResultsControlling for hospital characteristics, overdose burden, and socio-demographic characteristics, both Medicaid policies were associated with hospital adoption of several OUD programs. Hospitals in Medicaid expansion states had significantly higher odds of implementing any program related to SUDs (OR: 1.740; 95% CI: 1.032–2.934) as well as some specific activities such as programs for OUD treatment (OR: 1.955; 95% CI: 1.245–3.070) and efforts to address social determinants of health (OR: 6.787; 95% CI: 1.308–35.20). State 1115 waivers for SUDs were not significantly associated with any hospital-based SUD activities.ConclusionsMedicaid expansion was associated with several hospital programs for addressing OUD. The differential availability of hospital-based OUD programs may indicate an added layer of disadvantage for low-income patients with SUD living in non-expansion states.

Insurance Coverage and Forgoing Medical Appointments Because of Cost Among Cancer Survivors After 2016.

The uninsured rate began rising after 2016, which some have attributed to health policies undermining aspects of the Affordable Care Act. Our primary objectives were to assess the changes in insurance coverage and forgoing medical care because of cost in cancer survivors from pre-enactment (2016) through postenactment of those policies (2019) and determine whether there were subgroups that were disproportionately affected. The 2016-2019 Behavioral Risk Factor Surveillance System surveys were queried for 18- to 64-year-old cancer survivors. Survey-weighted logistic regression was used to assess temporal changes in (1) insurance coverage and (2) forgoing medical appointments because of cost in the preceding 12 months. A total of 62,669 cancer survivors were identified. The percentage of insured cancer survivors decreased from 92.4% in 2016 to 90.4% in 2019 (odds ratio for change in insurance coverage or affordability per one-year increase [ORyear], 0.92; 95% CI, 0.86 to 0.98; P = .01), translating to 161,000 fewer cancer survivors in the United States with insurance coverage. There were decreases in employer-sponsored insurance coverage (ORyear, 0.89) but increases in Medicaid coverage (ORyear, 1.17) from 2016 to 2019. Forgoing medical appointments because of cost increased from 17.9% in 2016 to 20.0% in 2019 (ORyear, 1.05; 95% CI, 1.01 to 1.1; P = .025), affecting an estimated 169,000 cancer survivors. The greatest changes were observed among individuals with low income, particularly those residing in nonexpansion states. Between 2016 and 2019, there were 161,000 fewer cancer survivors in the United States with insurance coverage, and 169,000 forwent medical care because of cost.

The effects of Medicaid expansions on dental services at federally qualified health centers

BackgroundFederally qualified health centers (FQHCs) have become safety-net providers of dental services for low-income patients. The authors examined the effects of the Patient Protection and Affordable Care Act Medicaid expansions, according to level of dental benefits, on the number of visits for dental services at FQHCs. MethodsThe authors used publicly available facility-level data on 1,400 FQHCs across the United States from the 2011 through 2019 Uniform Data System. The authors used an event-study difference-in-difference design to examine the effects of expanding Medicaid in 2014, according to the level of dental benefits, compared with nonexpansion states. Outcomes included the number of dental visits for any dental service and separately for preventive and other services. Regression models adjusted for the demographic characteristics of the FQHC's patient population, county-level factors, and center and year fixed effects. ResultsExpanding Medicaid with extensive dental benefits has increased the number of dental visits provided at FQHCs in 2014 through 2019 from 2013 by 1,329 to 7,647 visits per FQHC on average compared with FQHCs in nonexpansion states. There was an increase in visits for both preventive and other dental services. In contrast, there was no evidence of such an increase from expanding Medicaid with limited or emergency-only dental benefits. ConclusionsExpanding Medicaid eligibility with extensive dental benefits has increased the number of dental visits at FQHCs, including for both preventive and other dental services. Practical ImplicationsAs safety-net providers, FQHCs might be able to provide more oral health care for low-income patients after Medicaid expansions that offer extensive dental benefits.

Racial/Ethnic Differences in Association Between Medicaid Expansion and Causes and Costs of Readmission After Acute Ischemic Stroke.

The purpose of this study was to examine whether the relative frequency of leading causes and total associated costs of readmission after acute ischemic stroke changed with Medicaid expansion, and how these changes differed by racial/ethnic group. We used a difference-in-differences approach to compare changes in the relative frequency of leading causes of unplanned 30-day readmission and to examine changes in the costs associated with unplanned readmission between expansion states (AR, MD, NM, and WA) and non-expansion states (FL and GA). To estimate the differential effect of Medicaid expansion by race/ethnicity on the causes and cost of readmission, we added a time*treatment*race interaction. Multinomial logistic regression was performed to analyze the changes in readmission cause. Gamma log-link modeling was used to study changes in readmission costs for expansion compared to non-expansion states. The final multinomial model showed an association between expanded Medicaid and the relative frequency of sepsis readmission for White patients. According to predictive margins, White patients in expansion states had an estimated increase of 3.3 percentage points in the share of readmissions for sepsis but not for White patients in non-expansion states. In contrast, non-White patients in expansion states had a decrease of 1.8 percentage points in the share of readmissions for sepsis. Overall, Medicaid expansion was associated with a net increase of 6.7 percentage points in the share of readmissions for sepsis among non-Hispanic Whites relative to all other groups. In the final gamma model, Medicaid expansion was associated with a decrease in readmission costs overall. According to predictive margins, the net cost reduction in expansion versus non-expansion states was an average of $2509. Medicaid expansion is associated with an overall decrease in unplanned readmission costs and an increase among readmitted White patients in the likelihood of readmission for sepsis.

Long-Term Impact of Medicaid Expansion on Colorectal Cancer Screening in Its Targeted Population.

Colorectal cancer screening continuously decreased its mortality and incidence. In 2010, the Affordable Care Act extended Medicaid eligibility to low-income and childless adults. Some states elected to adopt Medicaid at different times while others chose not to. Past studies on the effects of Medicaid expansion on colorectal cancer screening showed equivocal results based on short-term data following expansion. To examine the long-term impact of Medicaid expansion on colorectal cancer screening among its targeted population at its decade mark. Behavioral Risk Factor Surveillance System data were extracted for childless adults below 138% federal poverty level in states with different Medicaid expansion statuses from 2012 to 2020. States were stratified into very early expansion states, early expansion states, late expansion states, and non-expansion states. Colorectal cancer screening prevalence was determined for eligible respondents. Difference-in-differences analyses were used to examine the effect of Medicaid expansion on colorectal cancer screening in states with different expansion statuses. Colorectal cancer screening prevalence in very early, early, late, and non-expansion states all increased during the study period (40.45% vs. 48.14%, 47.52% vs 61.06%, 46.06% vs 58.92%, and 43.44% vs 56.70%). Difference-in-differences analysis showed significantly increased CRC screening prevalence in very early expansion states during 2016 compared to non-expansion states (Crude difference-in-differences + 16.45%, p = 0.02, Adjusted difference-in-differences + 15.9%, p = 0.03). No statistical significance was observed among other years and groups. Colorectal cancer screening increased between 2012 and 2020 in all states regardless of expansion status. However, Medicaid expansion is not associated with long-term increased colorectal cancer screening prevalence.

Changes in receipt of adjuvant brachytherapy for endometrial cancer patients before and after affordable care act: The impact of Medicaid expansion.

For patients with high-intermediate risk (HIR) endometrial cancer, adjuvant radiation (RT) reduces the risk of recurrence, but many patients do not receive RT. Under the Affordable Care Act (ACA), most states expanded Medicaid coverage. Our hypothesis was patients would be more likely to receive indicated adjuvant RT in states that expanded Medicaid compared with patients in states that did not expand Medicaid. National Cancer Database (NCDB) was used to identify patients aged 40-64 years with HIR endometrial adenocarcinoma, stage IA and grade 3 or stage IB and grade 1 or 2, diagnosed from 2010-2018. We conducted a difference-in-differences (DID) cross-sectional retrospective analysis comparing receipt of adjuvant RT among patients residing in Medicaid expansion and non-expansion states before and after ACA implementation (January 2014). Expansion states had higher rates of adjuvant RT prior to January 2014 compared with non-expansion states (49.21% vs. 36.46%), and the proportion of patients who received adjuvant RT increased over the study period across both Medicaid expansion and non-expansion states. After Medicaid expansion, the non-expansion states had a larger absolute increase in adjuvant radiation resulting in a non-significant change in the difference in adjuvant radiation rates compared with baseline (crude increase: 9.63% vs. 7.45%, adjusted DID: -2.68 [95% CI: -7.12-1.75], p = 0.236). Medicaid expansion is likely not the most significant factor affecting access or receipt of adjuvant RT for HIR endometrial cancer patients. Further study could help inform policy and efforts to ensure all patients have access to guideline-recommended RT.

The Impact of the Affordable Care Act Medicaid Expansion on Acute Diabetes Complications Among Community Health Center Patients.

This study evaluates whether patients residing in expansion states have a greater increase in outpatient diagnoses of acute diabetes complications than those living in non-expansion states following the implementation of the Affordable Care Act (ACA). This retrospective cohort study uses electronic health records (EHR) from 10,665 non-pregnant patients, aged 19 to 64 years old who were diagnosed with diabetes in 2012 or 2013 from 347 community health centers (CHCs) across 16 states (11 expansion and 5 non-expansion states). Patients included had ≥1 outpatient ambulatory visit in each of these periods: pre-ACA: 2012 to 2013, post-ACA: 2014 to 2016, and post-ACA: 2017 to 2019. Acute diabetes-related complications were identified using International Classification Diseases (ICD-9-CM and ICD-10-CM) codes classification and could occur on or after diagnosis of diabetes. We performed difference-in-differences (DID) analysis using a generalized estimating equation to compare the change in rates of acute diabetes complications by year and by Medicaid expansion status. There was a greater increase after year 2015 in visits related to abnormal blood glucose among patient living in Medicaid expansion states than in non-expansion states (2017 DID = 0.041, 95% CI = 0.027-0.056). Although both visits due to any acute diabetes complications and infection-related diabetes complications were higher among patients living in Medicaid expansion states, there was no difference in the trend overtime between expansion and non-expansion states. We found a significantly greater rate of visits for abnormal blood glucose in patients receiving care in expansion states relative to patients in CHCs in non-expansion states starting in 2015. Additional resources for these clinics, such as the ability to provide blood glucose monitoring devices or mailed/delivered medications, could substantially benefit patients with diabetes.

Association of the Affordable Care Act on Access to and Outcomes After Kidney or Liver Transplant: A Transplant Registry Study

To evaluate the effect of the Affordable Care Act (ACA) Medicaid expansion on payor mix among patients on the kidney and liver transplant waiting list as well as waiting list and post-transplant outcomes. Using the Scientific Registry of Transplant Recipients, we performed a secondary data analysis of all patients on the kidney and liver transplant waiting list from 2007 to 2018. We described changes in payor mix by timing of state Medicaid expansion. We used competing risks models to estimate cause-specific hazard ratios for the effects of insurance and era on death/delisting and transplant. We used a Poisson regression model to estimate the effect of insurance and era on incidence rate ratio of inactivations on the waiting list. We used Cox proportional hazards models to estimate the effect of insurance and era on graft and patient survival. A decade after implementation of the ACA, the prevalence of Medicaid beneficiaries listed for transplant increased by 2.5% (from 7.4% to 9.9%) for kidney and by 2.6% (15.3% to 17.9%) for liver. Expansion states had greater increases than nonexpansion states (kidney 3.8% vs 0.6%, liver 5.3% vs -1.8%). Among wait-listed patients, the magnitude of association of Medicaid insurance vs private insurance with transplant decreased over time for kidney candidates (era 1 subdistribution hazard ratio (SHR), 0.62 [95% CI, 0.60-0.64] vs era 3 SHR, 0.77 [95% CI, 0.74-0.70]) but increased for liver candidates (era 1 SHR, 0.85 [95% CI, 0.83-0.90] vs era 3 SHR 0.79 [95% CI, 0.77-0.82]). Medicaid-insured kidney and liver recipients had greater hazards of graft failure; this did not change over time (kidney: HR, 1.23 [95% CI, 1.06-1.44] liver: HR, 1.05 [95% CI, 0.94-1.17]). For the millions of patients with chronic kidney and liver diseases, implementation of the ACA has resulted in only modest increases in access to transplant for the publicly insured vs the privately insured.

The Early Impact of the COVID-19 Pandemic on Hospital Finances.

The COVID-19 pandemic has caused both short- and long-term impacts on every aspect of society. Hospitals are among the most critical frontliners and have had to continually navigate the challenges caused by the pandemic. In this study, we examined hospitals' financial performance following the onset of the pandemic. We used data from the Centers for Medicare & Medicaid Services Healthcare Cost Report Information System. The study sample included all general acute care and critical access hospitals that receive Medicare payments. The primary outcomes included operating margins, net patient revenues, operating expenses, and uncompensated care costs. We tested for average changes from 2019 to 2020 in hospitals' financial outcomes. We also tested for changes in financial outcomes across samples stratified by hospital characteristics: ownership type (investor-owned, nonprofit, and public), Medicaid disproportionate share hospital status, rural status, county uninsured rate quartile, and Medicaid expansion status. Our sample consisted of a balanced panel of 4,059 hospitals (8,118 observations) with data spanning 2019 and 2020. Across the full sample of hospitals, operating margins declined by an average of 5.3 percentage points between 2019 and 2020, equating to a 130% reduction from 2019 levels. Underlying these margin declines, net patient revenues declined by 3.2% on average, while operating expenses increased by 1.5%. We observed no changes in uncompensated care costs despite the large number of job losses that accompanied the pandemic. When stratifying the analysis by hospital characteristics, differences were observed across ownership types. Notably, investor-owned facilities were less affected financially than nonprofit and public hospitals. Although safety-net and rural hospitals generally fared no worse than their non-safety-net and nonrural counterparts, hospitals located in Medicaid expansion states experienced steeper declines in operating margins relative to hospitals located in nonexpansion states, driven by larger relative declines in patient revenues. The operating margin declines we observed can be attributed to supply-chain issues, persistent labor shortages, and suspension of elective services. The Affordable Care Act reforms in health insurance markets likely helped to insulate hospitals from increases in uncompensated care costs. In the shifting context of the pandemic, it is important to understand hospitals' financial performance so that measures can be taken to address further financial distress that may eventually lead to increased consolidation, hospital closures, and lower quality of care. Our findings stress the need for targeted responses that are tailored to underlying hospital characteristics. Temporary and targeted increases in inpatient and outpatient service prices can help offset revenue losses from the deferment of nonurgent care. Other policies can address the ongoing workforce challenges and supply-chain issues.

Parental Immigration Status, Medicaid Expansion, And Supplemental Nutrition Assistance Program Participation.

Anti-immigrant public policies and rhetoric during 2017-19 may have eroded enrollment in safety-net programs, such as the enrollment of children of immigrants in the Supplemental Nutrition Assistance Program (SNAP). At the same time, states' expansion of Medicaid through the Affordable Care Act may have mitigated erosion through coordinated enrollment across safety-net programs, including SNAP and Medicaid. We examined changes in SNAP participation rates by parental immigration status among low-income households in 2015-16 versus 2017-19 for differences by child race and ethnicity or state Medicaid expansion status. Relative to those among citizen children with US-born parents, SNAP participation rates among citizen children from mixed-status families and noncitizen children significantly decreased between 2015-16 and 2017-19, with the magnitude of disparity widening over time. Declines in SNAP participation were sharper for Hispanic and Latino children from mixed-status families, Hispanic and Latino noncitizen children, and noncitizen children residing in nonexpansion states. Findings are consistent with some policy makers' concerns of erosion in SNAP participation. Mechanisms that could be employed to help reverse these trends include policies, outreach strategies, and enrollment processes.

Can Medicaid be a Solution to the Problem? Underinsurance in Medicaid Expansion Versus Non-Expansion States.

The positive effects of Medicaid expansions have been extensively documented in the literature. However, it is not clear whether the reform has had an equally meaningful effect with respect to underinsurance, which is the state of having health insurance yet lacking adequate coverage or facing substantial financial risks upon usage of services. Based on a quasi-experimental difference-in-differences approach, we analyzed the data from a nationally representative sample to estimate the effect of Medicaid expansion on the probability of underinsurance among the non-elderly low-income adult population of the U.S. We found no evidence of significant changes in the likelihood of underinsurance due to Medicaid expansion during the first 4 years after the ACA implementation. However, a supplementary analysis of the longer-term impact (2018-2019) suggests that there might be a time lag between Medicaid expansion and its effect on underinsurance. It is important to realize that expansion of coverage alone may not be sufficient to protect millions of Americans, particularly those with low incomes, from underinsurance. It is, therefore, crucial for policymakers to build legislative frameworks that protect individuals from excessive healthcare expenses and prevent treatment avoidance or delay.

Evaluating Changes in Surgical Outcomes for Patients With Inflammatory Bowel Disease Following Medicaid Expansion.

Little is known about the impact of Medicaid expansion on the surgical care of inflammatory bowel disease. We sought to determine whether Medicaid expansion is associated with improved postsurgical outcomes for patients with inflammatory bowel disease undergoing a colorectal resection. We performed a risk-adjusted difference-in-difference study examining postsurgical outcomes for patients ages 26 to 64 with Crohn's disease or ulcerative colitis undergoing a colorectal resection across 15 states that did and did not expand Medicaid before (2012-2013) and after (2016-2018) policy reform. Primary study outcomes included 30-day readmission and postoperative complication. Study population included 11 394 patients with inflammatory bowel disease that underwent a colorectal resection. States that underwent Medicaid expansion were associated with a rise in Medicaid enrollment following policy reform (11.8% pre-Medicaid expansion vs 19.7% post-Medicaid expansion). Difference-in-difference analysis revealed a statistically significant lower odds of 30-day readmission in patients undergoing a colorectal resection in expansion states following policy reform relative to patients in nonexpansion states prior to reform (odds ratio, 0.56; 95% confidence interval, 0.36-0.86). No changes in odds of postoperative complication were noted across expansion and nonexpansion states. Medicaid expansion is associated with a rise in Medicaid enrollment in expansion states following policy reform. There were greater improvements in postoperative outcomes associated with patients in expansion states following policy reform relative to patients in nonexpansion states prior to reform, which may have been related to improved perioperative care and medical management.

Duration and Continuity of Medicaid Enrollment Before the COVID-19 Pandemic

COVID-19 relief legislation created a temporary moratorium on Medicaid disenrollment, but when the public health emergency ends, states will begin to "unwind" Medicaid enrollment. Prepandemic data shed light on factors that can affect Medicaid coverage stability. To assess factors associated with the duration and continuity of Medicaid enrollment. In this cross-sectional analyses of a Medicaid data set for 2016 that was released by the Agency for Healthcare Research and Quality in June of 2022, we analyze a nationally representative data set of 5.7 million persons, weighted to represent 70 million Medicaid beneficiaries in 2016. We focus on 22 million nondisabled, nonelderly adults for this analysis. The data were analyzed between July and September of 2022. The main outcomes were the average months of Medicaid enrollment in 2016 and the probability of churning, defined as a break in coverage between 2 periods of enrollment during the calendar year. We compared these outcomes by eligibility category, state, demographic characteristics, and key Medicaid policies, including whether the state expanded Medicaid and whether it used ex parte reviews (automated reviews of other administrative data to reduce renewal paperwork burdens). In this cross-sectional analysis, we analyze a nationally representative Medicaid data set of 5.7 million persons, weighted to represent 70 million Medicaid beneficiaries in 2016, released by the Agency for Healthcare Research and Quality in June of 2022. The analysis focused on nonelderly, nondisabled adults (aged 18-64 years) with a weighted population size of 22.7 million, of which 18.4% were Black, 19.2% were Latino, 39.5% were White, 7.3% were other/Asian/Native American, and 15.5% had unknown race. Multivariable regression analysis indicated that those living in states that expanded Medicaid but did not use ex parte reviews had longer average duration (0.31 months longer; 95% CI, 0.03-0.59) and lower risk of churning(odds ratio [OR], .40; 95% CI, 0.39-0.40), whereas those living in nonexpansion states that used ex parte reviews had lower odds of churning (OR, .68; 95% CI, 0.66-0.70) but also had shorter average duration (3.1 months shorter; 95% CI, -3.4 to -2.8). Those living in expansion states that used ex parte reviews also had reduced churning (OR, .83; 95% CI, 0.82-0.85). The average duration varied widely by state, even after adjustments for demographic and state policy factors. If state Medicaid programs revert to prepandemic policies after the temporary moratorium ends, Medicaid coverage, particularly for nondisabled, nonelderly adults, is likely to become less stable again. Medicaid expansions are associated with improved continuity, but ex parte review may have a more complex role.

Survival in Young Adults With Cancer Is Associated With Medicaid Expansion Through the Affordable Care Act.

Medicaid expansion through the Affordable Care Act (ACA) has been shown to improve insurance coverage and early diagnosis of cancer in young adults (YAs); whether these improvements translate to survival benefits remains unknown. We examined the association between Medicaid expansion under the ACA and 2-year overall survival among YAs with cancer. Using the National Cancer Database, we identified 345,413 YAs (age 18-39 years) diagnosed with cancer in 2010-2017. We applied the difference-in-differences (DD) method to estimate changes in 2-year overall survival after versus before Medicaid expansion in expansion versus nonexpansion states. Among all YAs, 2-year overall survival increased more in expansion states (90.39% pre-expansion to 91.85% postexpansion) than in nonexpansion states (88.98% pre-expansion to 90.07% postexpansion), resulting in a net increase of 0.55 percentage points (ppt; 95% CI, 0.13 to 0.96). The expansion-associated survival benefit was concentrated in patients with female breast cancer (DD, 1.20 ppt; 95%CI, 0.27 to 2.12) when stratifying by cancer type and in patients with stage IV disease (DD, 2.56; 95%CI, 0.36 to 4.77) when stratifying by stage. In addition, greater survival benefit associated with Medicaid expansion was observed among racial and ethnic minoritized groups (DD, 1.01 ppt; 95% CI, 0.14 to 1.87) as compared with non-Hispanic White peers (DD, 0.41 ppt; 95% CI, -0.06 to 0.87) and among patients with a Charlson comorbidity score of ≥ 2 (DD, 6.48 ppt; 95% CI, 0.81 to 12.16) than those with a comorbidity score of 0 (DD, 0.44 ppt; 95% CI, 0.005 to 0.87). Medicaid expansion under the ACA was associated with an improvement in overall survival among YAs with cancer, with survival benefits most pronounced among patients of under-represented race and ethnicity and patients with high-risk diseases.

Health insurance coverage during the COVID-19 pandemic: The role of Medicaid expansion.

Using data from the US Census Bureau's Household Pulse Survey, we analyzed the likelihood of loss of health insurance and enrollment into new health coverage during the early months of the COVID-19 pandemic. Loss of employment was associated with a significant increase in the likelihood of loss of health insurance and, specifically, an increase in the likelihood of employer-sponsored health insurance. However, individuals in Medicaid expansion states experienced a lower likelihood of loss of health insurance compared with individuals in nonexpansion states. At the same time, there was a statistically significant increase in Medicaid enrollment in expansion states, by 3.2 percentage points. Reemployment or acquiring employment was associated with a gain in health insurance coverage. During an economic downturn, eligibility, and coverage gaps leave many without affordable coverage options, and the pandemic will likely bring renewed attention to gaps in Medicaid coverage in nonexpansion states.

The Differential Impact of the COVID-19 Pandemic on Prenatal Care Utilization Among US Women by Medicaid Expansion and Race and Ethnicity.

The 2014 Medicaid expansion improved racial and ethnic equity in insurance coverage and access to maternal care among women of reproductive age. This study examines differential effects of the COVID-19 pandemic on prenatal care utilization by Medicaid expansion and by race and ethnicity. Using the pooled 2019-2020 National Natality file (N = 7 361 190), logistic regression was used to estimate the effect of COVID-19 on prenatal care utilization among US women aged 10 to 54 years after controlling for maternal age, race, ethnicity, marital status, parity, nativity/immigrant status, education, payment type, and smoking during pregnancy. Outcome measures were having no care and delayed prenatal care (third trimester or no care). Stratified models by race/ethnicity and Medicaid expansion status yielded the differential effects of COVID-19 on prenatal care utilization. During the COVID-19 pandemic, the adjusted odds of having no prenatal care decreased by 4% (adjusted odds ratio [AOR] = 0.96; 95% confidence interval [CI], 0.94-0.97) in expansion states but increased by 13% (AOR = 1.13; 95% CI, 1.11-1.15) in nonexpansion states. While most racial and ethnic groups in expansion states experienced a decrease in having no prenatal care, the adjusted odds of having no prenatal care increased by 15% for non-Hispanic Whites, 9% for non-Hispanic Blacks, 33% for American Indians/Alaska Natives, 25% for Asian/Pacific Islanders, and 13% for Hispanics in nonexpansion states. Women in expansion states experienced no change in delayed prenatal care during the pandemic, but women in nonexpansion states experienced an increase in delayed care. Prenatal care utilization decreased during the pandemic among women in nonexpansion states, particularly for American Indians/Alaska Natives and Asian/Pacific Islanders, compared with expansion states.

Effects of Recent Medicaid Expansions on Infant Mortality by Race and Ethnicity

The purpose of this study is to examine year-by-year effects of the 2014 Affordable Care Act Medicaid expansion on infant mortality by race and ethnicity over the first 6 years. Publicly available 2011-2019 Multiple Cause of Death data were extracted in October and analyzed by November 2021. A difference-in-differences event-study design compared infant mortality changes in states that expanded in 2014 to nonexpansion states. In the main model, the 2014 Medicaid expansions were associated with a statistically significant decline in Black infants' mortality in 2018 and 2019 by 1.19 (95% CI= -2.27, -0.12) and 1.35 (95% CI= -2.45, -0.26) deaths per 1,000 live births, respectively. There was also a decline in mortality for Hispanic infants in 2015-2019, including by 0.8 (95% CI= -1.25, -0.36) and 1.28 (95% CI= -1.88, -0.68) deaths per 1,000 live births in 2015 and 2019, respectively. Overall, infant mortality declined by 0.37 (95% CI= -0.70, -0.05) deaths per 1,000 live births in 2019. The study adds evidence on the association of the Affordable Care Act Medicaid expansions with a decline in mortality of Black and Hispanic infants. The findings shed light on the importance of examining year-by-year effects over multiple years.

What Explains Changes in Availability of Specialty Mental Health Services in Organized Settings?

Community mental health facilities often do not offer the full range of evidence-based clinical and support services for individuals with serious mental illness. This creates equity issues, particularly when low-income and minority communities have access to fewer facilities. Medicaid expansion might encourage facilities to offer these services. However, this decision may also be affected by facility ownership type or mediated by service cost structure, particularly in the absence of innovative payment mechanisms. In this study, we determine whether and how Medicaid expansion and facility ownership are associated with changes in specialty mental health service availability in organized settings over time. We estimated two-way fixed effects models using six cross-sections of the National Mental Health Services Survey and compared changes in facility-reported offering of seven services from 2010 to 2019 (54,885 facility years): psychotropic medication, case management, family psychoeducation, psychiatric emergency walk-in services, supported employment, assertive community treatment, illness management, and recovery services. We tested whether Medicaid expansion and facility ownership (private for-profit, private not-for-profit, public) were associated with differential changes in service availability from 2010 to 2019. Overall, facilities were no more likely to offer nearly all services in 2019 than 2010. We found smaller declines for psychotropic medication and psychiatric emergency walk-in services among facilities in Medicaid expansion states compared to declines in non-Medicaid expansion states (6.3 (95% CI 95% CI = 1.8-10.7) and 5.5 (95% CI = 0.2-10.8) percentage points respectively). For-profit facilities experienced the largest declines in availability from 2010 to 2019, while public facilities experienced the smallest declines and some increases in availability of select services. Specialty mental health services are still not widely offered in community outpatient settings despite significant investments in Medicaid, although Medicaid expansion was associated with slower declines in availability. New payment models that incentivize outpatient facilities to offer clinical and support services may be needed.
