Did Medicaid expansion close African American-white health care disparities nationwide? A scoping review

Impact of the Affordable Care Act on Revascularization Versus Amputation in Patients Presenting With Chronic Limb-Threatening Ischemia in Maryland

INTRODUCTION

The Affordable Care Act (ACA) aimed to expand Medicaid, enhance health care quality and efficiency, and address health disparities. These goals have potentially influenced medical care, notably revascularization rates in patients presenting with chronic limb-threatening ischemia (CLTI). This study examines the effect of the ACA on revascularization vs amputation rates in patients presenting with CTLI in Maryland.

METHODS

This was a retrospective analysis of the Maryland State Inpatient Database comparing the rate of revascularization to rate of major amputation in patients presenting with CLTI over 2 periods: pre-ACA (2007-2009) and post-ACA (2018-2020). In this study, we included patients presenting with CLTI and underwent a major amputation or revascularization during that same admission. Using regression analysis, we estimated the odds of revascularization vs amputation pre- and post-ACA implementation, adjusting for pertinent variables.

RESULT

During the study period, 12,131 CLTI patients were treated. Post-ACA, revascularization rate increased from 43.9% to 77.4% among patients presenting with CLTI. This was associated with a concomitant decrease in the proportion of CLTI patients undergoing major amputation from 56.1% to 22.6%. In the multivariate analysis, there was a 4-fold odds of revascularization among patients with CLTI compared to amputation (OR = 4.73, 95% CI 4.34-5.16) post-ACA. This pattern was seen across all insurance groups.

CONCLUSION

The post-ACA period in Maryland was associated with an increased revascularization rate for patients presenting with CLTI with overall benefits across all insurance types.

United States Veterans' Utilization of Spinal Cord Injuries and Disorders Annual Evaluation Services

OBJECTIVE

To evaluate Veterans' engagement in spinal cord injury and disorder (SCI/D) specialty annual evaluations (AEs).

DESIGN

Cross-sectional retrospective cohort study.

SETTING

SCI/D System of Care, United States Department of Veterans Affairs (VA).

PARTICIPANTS

Veterans with SCI/Ds (N=14,662).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Receiving SCI/D AEs during the study period (fiscal years [FY] 2019 and 2020).

RESULTS

A total of 14,662 Veterans with SCI/Ds were included in the sample; 32.8% (n=4811) received 2 AEs, 28.8% (n=4219) received 1 AE, and 38.4% (n=5632) received no AEs, with an average of 0.9 AEs per Veteran over the 2-year study timeframe (range, 0-2y). Black Veterans had an 8% higher number of AEs than White Veterans after adjusting for other variables (adjusted relative risk [RR], 1.08; 95% confidence interval [CI], 1.04-1.12). Veterans who lived ≥240 minutes away from a VA SCI/D System of Care Center had 45% fewer AEs than Veterans who lived within 30 minutes (adjusted RR, 0.55; 95% CI, 0.52-0.59). Veterans with more SCI/D specialty visits had 90% more AEs than those with fewer visits (adjusted RR, 1.90; 95% CI, 1.78-2.03), whereas Veterans with more outpatient visits in VA primary care had 28% fewer AEs (adjusted RR, 0.72; 95% CI, 0.69-0.76). Veterans with higher comorbidity scores had 9% more AEs than Veterans with lower scores (adjusted RR, 0.66; 95% CI, 0.61-0.70).

CONCLUSIONS

More than half (62%) of Veterans received ≥1 SCI/D AE during FY19-20. Veterans living closer to a VA SCI/D System of Care Center/Hub had more engagement in SCI/D AEs. Veterans with SCI/Ds who used VA primary care outside of the SCI/D System of Care had fewer AEs. There were no major racial, age-based, or sex disparities in SCI/D AE usage. Our findings suggest the need for targeted intervention efforts to promote AE use among Veterans.

Racial and ethnic disparities in treatment refusal for head and neck cutaneous malignancies

Racial and ethnic minorities with skin cancer experience disproportionately worse prognoses and adverse outcomes compared to non-Hispanic, White patients. We analyzed patients diagnosed with any cutaneous malignancies of the head and neck between 2010 to 2021 using the data from the National Cancer Database to quantify disparities. The primary outcome variable was treatment refusal, and secondary variables included days from diagnosis to treatment, tumor depth, and mortality. Among the 151,733 patients analyzed, most were non-Hispanic White (99%) and male (71%). Black patients had the greatest odds of treatment refusal (4.166, 95% CI: 2.054-8.452, p < 0.001) across all cutaneous malignancies of the head and neck. Black and Hispanic patients also had increased times from diagnosis to treatment (p < 0.001). Black patients had higher odds of 90-day mortality compared to non-Hispanic White patients (p < 0.001). This coincided with greater tumor depth in Black and Hispanic patients compared to that of non-Hispanic White patients (p < 0.001). Black patients were more likely to refuse treatment for head and neck cutaneous malignancies. Moreover, Black and Hispanic patients experienced more treatment delays. These findings may relate to the increased 90-day mortality among Black patients and increased tumor depth in Black and Hispanic patients. Further investigation into the quality of life and functional impairment is warranted alongside interventions to reduce these disparities.

Association of Medicaid expansion with access to thyroidectomy for benign disease at high-volume centers

BACKGROUND

Insurance-based disparities in access to thyroidectomy are well established. Patients undergoing thyroidectomy by high-volume surgeons have fewer complications and better postoperative outcomes. The aim of this study was to evaluate the association of Medicaid expansion with access to high-volume centers for thyroidectomy for benign disease.

METHODS

The Vizient Clinical Data Base was queried for adult operations for benign thyroid disease from 2010 to 2019. Centers were sorted by volume into quartiles. Difference-in-difference analysis evaluated changes in insurance populations in expansion and non-expansion states after Medicaid expansion. Odds of patients undergoing operations in the 4 volume quartiles after stratifying by insurance and Medicaid expansion status were calculated.

RESULTS

A total of 82,602 patients underwent operations at 364 centers. Expansion states increased Medicaid coverage in all volume quartiles compared to non-expansion states after Medicaid expansion (Q1, +4.87%, Q2, +5.35%, Q3, +8.57%, Q4, +4.62%, P < .002 for all). After Medicaid expansion, Medicaid patients had higher odds of undergoing operation at lower volume hospitals compared to the highest volume centers in both expansion states (Q1, ref, Q2, 1.82, Q3, 1.76, Q4, 1.67, P < .001) and non-expansion states (Q1, ref, Q2, 1.54, Q3, 2.04, Q4, 1.44, P < .001). Privately insured patients were most likely to undergo their operation at the highest volume centers in all states (E: Q1, ref, Q2, 0.78, Q3, 0.74, Q4, 0.66, P < .001; NE: Q1, ref, Q2, 0.89, Q3, 0.58, Q4, 0.85, P < .001).

CONCLUSION

Medicaid expansion increased Medicaid coverage in expansion states, but Medicaid patients in both expansion and non-expansion states were less likely to be operated on at the highest volume centers compared to privately insured patients. Persistent barriers to accessing high-volume care still exists for Medicaid patients.

General surgery textbooks and surgical disparities

INTRODUCTION

Some academic textbooks have previously disseminated simplistic or even incorrect conceptions of race. Propagation of such ideas in General Surgery could contribute to gaps in quality of care received by minority patients. This study aims to determine whether General Surgery textbooks provide a thorough understanding of racial disparities.

METHODS

General Surgery texts were drawn from Doody's list, an industry-standard list of textbooks for medical education. Technical guides, atlases, and books for non-General Surgery professionals were excluded. Passages mentioning medical differences amongst racial and ethnic groups were extracted. Six binary classifications were made, based on whether passages (a) described interventions to alleviate difference; (b) addressed environmental mediators of difference; (c) described the contribution of racism or discrimination; (d) used causal language to connect race to difference; (e) referred to known, heritable genetic mechanisms; and (f) directly provided a reference. Types of intervention were also extracted. A heuristic scale was calculated granting one point each for classifications a-c and losing one point for classification d. Three authors performed classifications, and raw agreement and Cohen's kappa were used to assess inter-rater reliability.

RESULTS

Thirteen textbooks from Doody's list contained 511 passages discussing medical differences among racial/ethnic groups. Among passages, 25% discussed white people, 22% Black people/African Americans, 19% Asians, 9% Latinos, 4% Jewish/Ashkenazi people, 3% Native Americans, and 18% other. Fifteen passages (2.9%) used language indicating race was the cause of medical difference, and only two explicitly discussed racism or discrimination. Most passages (370, 72.3%) received a scale of 0. 120 (23.5%) received a scale of 1, eight (1.2%) received a scale of 2, and zero received a scale of 3. The mean passage scale was 0.24 and is not changing with time (regression coefficient -0.006/year, p = 0.538). Agreement was 91.2% across all categories and overall Kappa was 0.62.

CONCLUSIONS

General Surgery textbooks do not provide readers with scientifically thorough understanding of health disparities. Teaching more comprehensive conceptions, including systemic causes and the role of racism, may prevent reflexive association of minority patients with poor outcomes. Future editions should include these details where disparities are discussed in an independent, comprehensive section.

Medicaid Expansion and Racial-Ethnic and Sex Disparities in Cardiovascular Diseases Over 6 Years: A Generalized Synthetic Control Approach

BACKGROUND

Studies have suggested Medicaid expansion enacted in 2014 has resulted in a reduction in overall cardiovascular disease (CVD) mortality in the United States. However, it is unknown whether Medicaid expansion has a similar effect across race-ethnicity and sex. We investigated the effect of Medicaid expansion on CVD mortality across race-ethnicity and sex.

METHODS

Data come from the behavioral risk factor surveillance system and the US Centers for Disease Control's Wide-ranging Online Data for Epidemiologic Research, spanning the period 2000-2019. We used the generalized synthetic control method, a quasi-experimental approach, to estimate effects.

RESULTS

Medicaid expansion was associated with -5.36 (mean difference [MD], 95% confidence interval [CI] = -22.63, 11.91) CVD deaths per 100,000 persons per year among Blacks; -4.28 (MD, 95% CI = -30.08, 21.52) among Hispanics; -3.18 (MD, 95% CI = -8.30, 1.94) among Whites; -5.96 (MD, 95% CI = -15.42, 3.50) among men; and -3.34 (MD, 95% CI = -8.05, 1.37) among women. The difference in mean difference (DMD) between the effect of Medicaid expansion in Blacks compared with Whites was -2.18; (DMD, 95% CI = -20.20, 15.83); between that in Hispanics compared with Whites: -1.10; (DMD, 95% CI = -27.40, 25.20) and between that in women compared with men: 2.62; (DMD, 95% CI = -7.95, 13.19).

CONCLUSIONS

Medicaid expansion was associated with a reduction in CVD mortality overall and in White, Black, Hispanic, male, and female subpopulations. Also, our study did not find any difference or disparity in the effect of Medicaid on CVD across race-ethnicity and sex-gender subpopulations, likely owing to imprecise estimates.

Public Benefit Programs and Differential Associations With Child Maltreatment by Race and Ethnicity

Importance

Public benefit programs, including state spending on local, state, and federal-state partnership programs, have consistently been associated with overall reductions in child protective services (CPS) involvement. Inequities in eligibility and access to benefit programs may contribute to varying associations by race and ethnicity.

Objective

To determine whether associations between state spending on benefit programs and rates of CPS investigations differ by race and ethnicity.

Design, Setting, and Participants

This cross-sectional ecological study used repeated state-level measures of child maltreatment from the National Child Abuse and Neglect Data System and population estimates from the US Census Bureau for all Black, Hispanic, and White children. All 50 US states from October 1, 2009, through September 30, 2019 (fiscal years 2010-2019), were included. Data were collected and analyzed from May 13, 2022, to March 2, 2023.

Exposures

Annual state spending on benefit programs per person living below the federal poverty limit, total and by the following subcategories: (1) cash, housing, and in-kind; (2) housing infrastructure; (3) child care assistance; (4) refundable earned income tax credit; and (5) medical assistance programs.

Main Outcomes and Measures

Race- and ethnicity-specific rates of CPS investigations. Generalized estimating equations, with repeated measures of states, an interaction between race and spending, and estimated incidence rate ratios (IRRs) and 95% CIs for incremental changes in spending of US $1000 per person living below the federal poverty limit were calculated after adjustment for federal spending, race- and ethnicity-specific child poverty rate, and year.

Results

A total of 493 state-year observations were included in the analysis. The association between total spending and CPS investigations differed significantly by race and ethnicity: there was an inverse association between total state spending and CPS investigations for White children (IRR, 0.94 [95% CI, 0.91-0.98]) but not for Black children (IRR, 0.98 [95% CI, 0.94-1.02]) or Hispanic children (IRR, 0.99 [95% CI, 0.95-1.03]) (P = .02 for interaction). Likewise, inverse associations were present for only White children with respect to all subcategories of state spending and differed significantly from Black and Hispanic children for all subcategories except the refundable earned income tax credit (eg, IRR for medical assistance programs for White children, 0.89 [95% CI, 0.82-0.96]; P = .005 for race and spending interaction term).

Conclusions and Relevance

These results raise concerns that benefit programs may add relative advantages for White children compared with Black and Hispanic children and contribute to racial and ethnic disparities in CPS investigations. States' eligibility criteria and distribution practices should be examined to promote equitable effects on adverse child outcomes.

Clinical characteristics, treatment patterns, and outcomes among African American and White patients with multiple myeloma in the United States

Multiple myeloma (MM) is more common among Black/African American (AA) patients than White patients, but survival rate improvements are less pronounced for AA patients. This study evaluated treatment patterns and survival among 1810 AA and 5904 White adults in the United States with ≥1 MM treatment and ≥3 months of follow-up. Median time from diagnosis to systemic treatment was longer (37 [0-3053] vs. 35 [0-3664] days) and median time to stem cell transplant (SCT) was longer for AA than White patients (255 [1-2352] vs. 225 [1-3094] days), and AA patients were less likely to receive SCT (odds ratio [OR]: 0.66; 95% confidence interval [CI]: 0.58-0.76). Despite disparities in treatment between AA and White patients, AA patients demonstrated lower risk of death (OR: 0.89; 95% CI: 0.81-0.96). These data highlight the value of equal access to care for the improvement of health outcomes in underserved populations.

States' racial resentment correlates with administrative distancing and lower rates of health plan selection in affordable care act marketplaces: a cross sectional analysis

BACKGROUND

In the United States, the Affordable Care Act (ACA) pursued equity in healthcare access and treatment, but ACA implementation varied, especially limiting African Americans' gains. Marketplaces for subsidized purchase of coverage were sometimes implemented with limited outreach and enrollment assistance efforts. Reflecting state's ACA receptivity or reluctance, state's implementation may rest on sociopolitical stances and racial sentiments. Some states were unwilling to provide publicly supported healthcare to nonelderly, non-disabled adults- "the undeserving poor" -who evoke anti-black stereotypes. The present study assessed whether some states shunned Affordable Care Act (ACA) marketplaces and implemented them less vigorously than other states, leading to fewer eligible persons selecting insurance plans. It assessed if states' actions were motivated by racial resentment, because states connote marketplaces to be government assistance for unworthy African Americans.

METHODS

Using marketplace and plan selection data from 2015, we rated states' marketplace structures along a four-level continuum indicating greater acceptance of marketplaces, ranging from states assuming sole responsibility to minimal responsibility. Using national data from a four-question modern racism scale, state-wide racial resentment estimates were estimated at the state level. Analysis assessed associations between state levels of racial resentment with states' marketplace structure. Further analysis assessed relationships between both state levels of racial resentment and states' marketplace structure with states' consumer plan selection rates-representing the proportion of persons eligible to enroll in insurance plans who selected a plan.

RESULTS

Racial resentment was greater in states with less responsibility for the administration of the marketplaces than actively participating states. States higher in racial resentment also showed lower rates of plan selection, pointing to less commitment to implementing marketplace provisions and fulfilling the ACA's coverage-improvement mission. Differences persisted after controlling for differences in conservatism, uninsurance, poor health, and rejection of Medicaid expansion.

CONCLUSIONS

Resentment of African Americans' purported irresponsibility and entitlement to government assistance may interfere with states structuring and operating marketplaces to maximize health insurance opportunities for everyone available under the ACA.

Time to surgery: A health equity metric in breast cancer patients

BACKGROUND

We evaluated whether time to surgery by race can be a health equity metric of surgical access.

METHODS

An observational analysis was performed using the National Cancer Database from 2010 to 2019. Inclusion criteria were women with stage I-III breast cancer. We excluded women with multiple cancers and whose diagnosis was made at a different hospital. The primary outcome variable was surgery within 90 days of diagnosis.

RESULTS

A total of 886,840 patients were analyzed, with 76.8% White and 11.7% Black patients. 11.9% of patients experienced delayed surgery, which was significantly more common in Black patients than White patients. On adjusted analysis, Black patients were still significantly less likely to receive surgery within 90 days when compared to White patients (OR 0.61, 95% CI 0.58-0.63).

CONCLUSION

The delay in surgery experienced by Black patients highlights the contribution of system factors in cancer inequity and should be a focus for targeted interventions.
