Weisz D, Gusmano MK, Amba V, Rodwin VG. Has the Expansion of Health Insurance Coverage via the Implementation of the Affordable Care Act Influenced Inequities in Coronary Revascularization in New York City? J Racial Ethn Health Disparities 2024; 11:1783-1790. [PMID: 37338791 DOI: 10.1007/s40615-023-01650-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 05/14/2023] [Accepted: 05/15/2023] [Indexed: 06/21/2023]
Abstract
BACKGROUND/PURPOSE In 2014, New York City implemented the Affordable Care Act (ACA) leading to insurance coverage gains intended to reduce inequities in healthcare services use. The paper documents inequalities in coronary revascularization procedures (percutaneous coronary intervention and coronary artery bypass grafting) usage by race/ethnicity, gender, insurance type, and income before and after the implementation of the ACA. METHODS We used data from the Healthcare Cost and Utilization Project to identify NYC patients hospitalized with the diagnosis of coronary artery disease (CAD) and/or congestive heart failure (CHF) in 2011-2013 (pre-ACA) and 2014-2017 (post-ACA). Next, we calculated age-adjusted rates of CAD and/or CHF hospitalization and coronary revascularization. Logistic regression models were used to identify the variables associated with receiving a coronary revascularization in each period. RESULTS Age-adjusted rates of CAD and/or CHF hospitalization and coronary revascularization in patients 45-64 years of age and 65 years of age and older declined in the post-ACA period. Disparities by gender, race/ethnicity, insurance type, and income in the use of coronary revascularization persist in the post-ACA period. CONCLUSIONS Although this health care reform law led to the narrowing of inequities in the use of coronary revascularization, disparities persist in NYC in the post-ACA period.

Abstract
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.

Abstract
This study examines whether the Affordable Care Act (ACA) Medicaid expansion (ME) was associated with changes in racial/ethnic disparities in insurance coverage, utilization, and quality of mental health care among low-income adults with probable mental illness using the National Survey on Drug Use and Health with state identifiers. This study employed difference-in-difference models to compare ME states to non-expansion states before (2010-2013) and after (2014-2017) expansion and triple difference models to examine these changes across non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic/Latino racial/ethnic subgroups. Insurance coverage increased significantly for all racial/ethnic groups in expansion states relative to non-expansion states (DD: 9.69; 95% CI: 5.17, 14.21). The proportion low-income adults that received treatment but still had unmet need decreased (DD: -3.06; 95% CI: -5.92, -0.21) and the proportion with unmet need and no mental health treatment increased (DD: 2.38; 95% CI: 0.03, 4.73). ME was not associated with reduced disparities.

Racial/ethnic differences persist in treatment choice and outcomes in isolated intervention for coronary artery disease. J Thorac Cardiovasc Surg 2023; 166:1087-1096.e5. [PMID: 35248359 PMCID: PMC11092967 DOI: 10.1016/j.jtcvs.2022.01.034] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 12/10/2021] [Accepted: 01/23/2022] [Indexed: 10/19/2022]
Abstract
OBJECTIVE Studies have noted racial/ethnic disparities in coronary artery disease intervention strategies. We investigated trends and outcomes of coronary artery disease treatment choice (coronary artery bypass grafting or percutaneous coronary intervention) stratified by race/ethnicity. METHODS We queried the National Inpatient Sample for patients who underwent isolated coronary artery bypass grafting or percutaneous coronary intervention (2002-2017). Outcomes were stratified by race/ethnicity (White, African American, Hispanic, Asian). Multivariable logistic regression evaluated associations between race/ethnicity and receiving coronary artery bypass grafting versus percutaneous coronary intervention, in-hospital mortality, and costs. RESULTS Over the 15-year period, 2,426,917 isolated coronary artery bypass grafting surgeries and 7,184,515 percutaneous coronary interventions were performed. Compared with White patients, African American patients were younger (62 [interquartile range, 53-70] vs 66 [interquartile range, 57-75] years), were more likely to have Medicaid insurance (12.2% vs 4.4%), and had more comorbidities (Charlson-Deyo index, 1.9 ± 1.6 vs 1.7 ± 1.6) (all P < .01). After adjustment for patient comorbidities, presence of acute myocardial infarction, insurance status, and geography, African Americans were the least likely of all racial/ethnic groups to undergo coronary artery bypass grafting (odds ratio, 0.76; P < .01), a consistent trend throughout the study. African American patients had higher risk-adjusted mortality after coronary artery bypass grafting (odds ratio, 1.09; P < .01). Race/ethnicity was not associated with increased mortality after percutaneous coronary intervention. African American patients had higher hospitalization costs for coronary artery bypass grafting (+$5816; P < .01) and percutaneous coronary intervention (+$856; P < .01) after controlling for confounders. CONCLUSIONS In this contemporary national analysis, risk-adjusted frequency of coronary artery bypass grafting versus percutaneous coronary intervention for coronary artery disease differed by race/ethnicity. African American patients had lower odds of undergoing coronary artery bypass grafting and worse outcomes. Reasons for these differences merit further investigation to identify opportunities to reduce potential disparities.

J Vasc Surg 2023; 78:648-656.e6. [PMID: 37116595 DOI: 10.1016/j.jvs.2023.04.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 04/04/2023] [Accepted: 04/17/2023] [Indexed: 04/30/2023]
Abstract
OBJECTIVE Lack of insurance has been independently associated with an increased risk of in-hospital mortality after abdominal aortic aneurysm repair, possibly due to worse control of comorbidities and delays in diagnosis and treatment. Medicaid expansion has improved insurance rates and access to care, potentially benefiting these patients. We sought to assess the association between Medicaid expansion and outcomes after abdominal aortic aneurysm repair. METHODS A retrospective analysis of Healthcare Cost and Utilization Project State Inpatient Databases data from 14 states between 2012 and 2018 was conducted. The sample was restricted to first-record abdominal aortic aneurysm repairs in adults under age 65 in states that expanded Medicaid on January 1, 2014 (Medicaid expansion group) or had not expanded before December 31, 2018 (non-expansion group). The Medicaid expansion and non-expansion groups were compared between pre-expansion (2012-2013) and post-expansion (2014-2018) time periods to assess baseline demographic and operative differences. We used difference-in-differences multivariable logistic regression adjusted for patient factors, open vs endovascular repair, and standard errors clustered by state. Our primary outcome was in-hospital mortality. Outcomes were stratified by insurance type. RESULTS We examined 8995 patients undergoing abdominal aortic aneurysm repair, including 3789 (42.1%) in non-expansion states and 5206 (57.9%) in Medicaid expansion states. Rates of Medicaid insurance were unchanged in non-expansion states but increased in Medicaid expansion states post-expansion (non-expansion: 10.9% to 9.8%; P = .346; expansion: 9.7% to 19.7%; P < .001). One in 10 patients from both non-expansion and Medicaid expansion states presented with ruptured aneurysms, which did not change over time. Rates of open repair decreased in both non-expansion and Medicaid expansion states over time (non-expansion: 25.1% to 19.2%; P < .001; expansion: 25.2% to 18.4%; P < .001). On adjusted difference-in-differences analysis between expansion and non-expansion states pre-to post-expansion, Medicaid expansion was associated with a 1.02% absolute reduction in in-hospital mortality among all patients (95% confidence interval, -1.87% to -0.17%; P = .019). Additionally, among patients who were either on Medicaid or were uninsured (ie, the patients most likely to be impacted by Medicaid expansion), a larger 4.17% decrease in in-hospital mortality was observed (95% confidence interval, -6.47% to -1.87%; P < .001). In contrast, no significant difference-in-difference in mortality was observed for privately insured patients. CONCLUSIONS Medicaid expansion was associated with decreased in-hospital mortality after abdominal aortic aneurysm repair among all patients and particularly among patients who were either on Medicaid or were uninsured. Our results provide support for improved access to care for patients undergoing abdominal aortic aneurysm repair through Medicaid expansion.

Abstract
Since 2014, American states have had the option to expand their Medicaid programs as part of the Affordable Care Act (ACA), which was signed into law by former President Barack H. Obama in 2010. Emerging research has found that Medicaid expansion has had a significant impact on patients with cancer, who often face significant financial barriers to receiving the care they need. In this review, we aim to provide a comprehensive examination of the research conducted thus far on the impact of Medicaid expansion on patients with cancer. We begin with a discussion of the history of Medicaid expansion and the key features of the ACA that facilitated it. We then review the literature, analyzing studies that have investigated the impact of Medicaid expansion on cancer patients in terms of access to care, quality of care, and health outcomes. Our findings suggest that Medicaid expansion has had a positive impact on patients with cancer in a number of ways. Patients in expansion states are more likely to receive timely cancer screening and diagnoses, and are more likely to receive appropriate cancer-directed treatment. Additionally, Medicaid expansion has been associated with improvements in cancer-related health outcomes, including improved survival rates. However, limitations and gaps in the current research on the impact of Medicaid expansion on patients with cancer exist, including a lack of long-term data on health outcomes. Additionally, further research is needed to better understand the mechanisms through which Medicaid expansion impacts cancer care.

Abstract
Distressed Communities Index (DCI) and Area Deprivation Index (ADI) are two composite ranking scores that report community level socioeconomic status (SES) by ZIP codes. The objective of this study was to evaluate the impact of SES as estimated by DCI and ADI scores on short-term and long-term outcomes after extracorporeal life support (ECLS) at a quaternary medical center. All patients on ECLS between January 1, 2015 and August 31, 2020 (N = 428) at Vanderbilt University Medical Center in Nashville, Tennessee, had their ADI and DCI scores calculated. Primary outcome was mortality during index hospitalization, and secondary outcome was survival to end of study follow-up. There was no significant difference in primary outcome between the top 25% ADI vs . bottom 75% ADI (53.8% vs . 50.6%; p = 0.56) or between top 25% DCI vs . bottom 75% DCI (56.1 vs . 49.2; p = 0.21). Adjusted odds ratio for the primary outcome with ADI and DCI was 1.13 (95% CI, 0.63-2.0; p = 0.67) and 1.28 (95% CI, 0.70-2.34; p = 0.41), respectively. Additionally, there was no significant difference in long-term survival curves based on their ADI or DCI scores. In conclusion, SES as estimated by baseline DCI and ADI scores does not appear to impact short- or long-term survival post-ECLS at a large volume center. http://links.lww.com/ASAIO/A951.

Abstract
BACKGROUND The goal of the Affordable Care Act was to improve health outcomes through expanding insurance, including through Medicaid expansion. We systematically reviewed the available literature on the association of Affordable Care Act Medicaid expansion with cardiac outcomes. METHODS Consistent with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, we performed systematic searches in PubMed, the Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature using the keywords such as Medicaid expansion and cardiac, cardiovascular, or heart to identify titles published from 1/2014 to 7/2022 that evaluated the association between Medicaid expansion and cardiac outcomes. RESULTS A total of 30 studies met inclusion and exclusion criteria. Of these, 14 studies (47%) used a difference-in-difference study design and 10 (33%) used a multiple time series design. The median number of postexpansion years evaluated was 2 (range, 0.5-6) and the median number of expansion states included was 23 (range, 1-33). Commonly assessed outcomes included insurance coverage of and utilization of cardiac treatments (25.0%), morbidity/mortality (19.6%), disparities in care (14.3%), and preventive care (41.1%). Medicaid expansion was generally associated with increased insurance coverage, reduction in overall cardiac morbidity/mortality outside of acute care settings, and some increase in screening for and treatment of cardiac comorbidities. CONCLUSIONS Current literature demonstrates that Medicaid expansion was generally associated with increased insurance coverage of cardiac treatments, improvement in cardiac outcomes outside of acute care settings, and some improvements in cardiac-focused prevention and screening. Conclusions are limited because quasi-experimental comparisons of expansion and nonexpansion states cannot account for unmeasured state-level confounders.

Abstract
In 1965, Medicaid was implemented with the goal of providing insurance to low-income individuals. In 2010, the Patient Protection Affordable Care Act (PPACA) standardized and expanded the eligibility criteria for the Medicaid program across the United States. In 2012, the constitutionality of this expansion was challenged and the Supreme Court rules that states were only required to expand their Medicaid program if they wanted to utilize the additional funds allotted by the federal government. This research paper examines the effects of the expansion by looking at health data in expansion and non-expansion states. Specifically, this study compares metrics designed to gauge healthcare access, health behaviors and health outcomes to determine if expansion has had positive overall effect on expansion states. We conclude that expansion states have demonstrated improved access to healthcare and improved health outcomes than the non-expansion states. Changes in health behaviors reflect mixed results - HIV screenings are higher in expansion states but participation in flu vaccinations show no statistical significance difference between the two groups. Given the results of this analysis, we conclude that Medicaid expansion is an effective policy for states to pursue in order to further the original objectives of Medicaid by improving the health of low-income recipients.

Abstract
BACKGROUND The association between Medicaid expansion and postoperative mortality after surgery for gynecologic cancer is unknown. Our objective was to compare 30- and 90-day postoperative mortality after gynecologic cancer surgery before and after 2014 in states that did and did not expand Medicaid. METHODS We searched the National Cancer Database for women aged 40-64 years old between 2010 and 2016 who underwent surgery for a primary gynecologic malignancy. We used pre/post and quasi-experimental difference-in-difference (DID) multivariable logistic regressions to evaluate mortality pre-2014 (2010-2013) and post-2014 (2014-2016) for states that did and did not expand Medicaid in January 2014. We completed univariable logistic regressions for covariates of interest. RESULTS Among 169,731 women, 30-day postoperative mortality in expansion states after 2014 significantly decreased for endometrial cancer (odds ratio [OR] 0.42, 95% confidence interval [CI] 0.26-0.67) and ovarian cancer (OR 0.67, 95% CI 0.46-0.99) and increased for cervical cancer (OR 3.82, 95% CI 1.12-13.01). Compared with non-expansion states, expansion states had improved 30-day postoperative mortality for endometrial cancer after 2014 (DID OR 0.54, 95% CI 0.31-0.96). Univariable analysis demonstrated improved 30-day postoperative mortality for Black women with endometrial cancer in expansion states (DID OR 0.22, 95% CI 0.05-0.95). There was improved 90-day postoperative mortality for endometrial cancer in expansion states (OR 0.66, 95% CI 0.50-0.85), and improved 90-day postoperative mortality for Midwestern women with ovarian cancer in expansion states on univariable analysis (DID OR 0.48, 95% CI 0.26-0.91). CONCLUSIONS State Medicaid legislation was associated with improved postoperative survival in women with endometrial cancer and subgroups of women with endometrial and ovarian cancer.

Abstract
INTRODUCTION Safety-net hospitals (SNHs) have higher postoperative complications and costs versus low-burden hospitals. Do low socioeconomic status/vulnerable patients receive care at lower-quality hospitals or are there factors beyond providers' control? We studied the association of private, Medicare, and vulnerable insurance type with complications/costs in a high-burden SNH. METHODS Retrospective inpatient cohort study using National Surgical Quality Improvement Program (NSQIP) data (2013-2019) with cost data risk-adjusted by frailty, preoperative serious acute conditions (PASC), case status, and expanded operative stress score (OSS) to evaluate 30-day unplanned reoperations, any complication, Clavien-Dindo IV (CDIV) complications, and hospitalization variable costs. RESULTS Cases (Private 1517; Medicare 1224; Vulnerable 3648) with patient mean age 52.3 y [standard deviation = 14.7] and 47.3% male. Adjusting for frailty and OSS, vulnerable patients had higher odds of PASC (aOR = 1.71, CI = 1.39-2.10, P < 0.001) versus private. Adjusting for frailty, PASC and OSS, Medicare (aOR = 1.27, CI = 1.06-1.53, P = 0.009), and vulnerable (aOR = 2.44, CI = 2.13-2.79, P < 0.001) patients were more likely to undergo urgent/emergent surgeries. Vulnerable patients had increased odds of reoperation and any complications versus private. Variable cost percentage change was similar between private and vulnerable after adjusting for case status. Urgent/emergent case status increased percentage change costs by 32.31%. We simulated "switching" numbers of private (3648) versus vulnerable (1517) cases resulting in an estimated variable cost of $49.275 million, a 25.2% decrease from the original $65.859 million. CONCLUSIONS Increased presentation acuity (PASC and urgent/emergent surgeries) in vulnerable patients drive increased odds of complications and costs versus private, suggesting factors beyond providers' control. The greatest impact on outcomes may be from decreasing the incidence of urgent/emergent surgeries by improving access to care.

Abstract
BACKGROUND Surgical outcome/cost analyses typically focus on single outcomes and do not include encounters beyond the index hospitalization. STUDY DESIGN This cohort study used NSQIP (2013-2019) data with electronic health record and cost data risk-adjusted for frailty, preoperative acute serious conditions (PASC), case status, and operative stress assessing cumulative costs of failure to achieve textbook outcomes defined as absence of 30-day Clavien-Dindo level III and IV complications, emergency department visits/observation stays (EDOS), and readmissions across insurance types (private, Medicare, Medicaid, uninsured). Return costs were defined as costs of all 30-day emergency department visits/observation stays and readmissions. RESULTS Cases were performed on patients (private 1,506; Medicare 1,218; Medicaid 1,420; uninsured 2,178) with a mean age 52.3 years (SD 14.7) and 47.5% male. Medicaid and uninsured patients had higher odds of presenting with preoperative acute serious conditions (adjusted odds ratios 1.89 and 1.81, respectively) and undergoing urgent/emergent surgeries (adjusted odds ratios 2.23 and 3.02, respectively) vs private. Medicaid and uninsured patients had lower odds of textbook outcomes (adjusted odds ratios 0.53 and 0.78, respectively) and higher odds of emergency department visits/observation stays and readmissions vs private. Not achieving textbook outcomes was associated with a greater than 95.1% increase in cumulative costs. Medicaid patients had a relative increase of 23.1% in cumulative costs vs private, which was 18.2% after adjusting for urgent/emergent cases. Return costs were 37.5% and 65.8% higher for Medicaid and uninsured patients, respectively, vs private. CONCUSIONS Higher costs for Medicaid patients were partially driven by increased presentation acuity (increased rates/odds of preoperative acute serious conditions and urgent/emergent surgeries) and higher rates of multiple emergency department visits/observation stays and readmission occurrences. Decreasing surgical costs/improving outcomes should focus on reducing urgent/emergent surgeries and improving postoperative care coordination, especially for Medicaid and uninsured populations.

The Differential Impact of Medicaid Expansion on Disparities in Outcomes Following Peripheral Vascular Intervention. Ann Vasc Surg 2022; 86:135-143. [PMID: 35460861 DOI: 10.1016/j.avsg.2022.04.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 04/06/2022] [Accepted: 04/07/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Peripheral artery disease (PAD) disproportionately affects nonwhite, Hispanic/Latino, and low socioeconomic status patients, who are less likely to have insurance and routine healthcare visits. Medicaid expansion (ME) has improved insurance rates and access to care, potentially benefitting these patients. We sought to assess the impact of ME on disparities in outcomes after peripheral vascular intervention (PVI) for PAD. METHODS A retrospective analysis of prospectively-collected Vascular Quality Initiative PVI procedures between 2011 and 2019 was conducted. The sample was restricted to first-record procedures in adults under the age 65 in states that expanded Medicaid on January 1, 2014 (ME group) or had not expanded before January 1, 2019 (non-expansion [NE] group). ME and NE groups were compared between pre-expansion (2011-2013) and post-expansion (2014- 2019) time periods to assess baseline demographic and operative differences. We used difference-in-differences multivariable logistic regression adjusted for patient factors and clinical center and year fixed effects. Our primary outcome was 1-year major amputation. Secondary outcomes included trends in presentation, 30-day mortality, 1-year mortality, and 1-year primary and secondary patency. Outcomes were stratified by race and ethnicity. RESULTS We examined 34,313 PVI procedures, including 20,378 with follow-up data. Rates of Medicaid insurance increased post-expansion in ME and NE states (ME 16.7% to 23.0%, P < 0.001; NE 10.0% to 11.9%, P = 0.013) while rates of self-pay decreased in ME states only (ME 4.6% to 1.8%, P < 0.001; NE 8.1% to 8.4%, P = 0.620). Adjusted difference-in-differences analysis revealed lower odds of urgent/emergent PVI among all patients and all nonwhite patients in ME states post-expansion compared to NE states (all: odds ratio [OR] 0.53 [95% confidence interval 0.33-0.87], P = 0.011; nonwhite: OR 0.41 [0.19-0.88], P = 0.023). No differences were observed for 1-year major amputation (OR 0.70 [0.43-1.14], P = 0.152), primary patency (OR 0.93 [0.63-1.38], P = 0.726), or secondary patency (OR 1.29 [0.69-2.41], P = 0.431). Odds of 1-year mortality were higher in ME states post-expansion compared to NE states (OR 2.50 [1.07-5.87], P = 0.035), although 30-day mortality was not different (OR 2.04 [0.60-6.90], P = 0.253). Notably, odds of 1-year major amputation among Hispanic/Latino patients decreased in ME states post-expansion compared to NE states (OR 0.11 [0.01-0.86], P = 0.036). CONCLUSIONS ME was associated with lower odds of 1-year major amputation among Hispanic/Latino patients who underwent PVI for PAD. ME was also associated with lower odds of urgent/emergent procedures among patients overall and nonwhite patients specifically. However, 1-year mortality increased in the overall cohort. Further study is needed to corroborate our findings that ME may have benefits for certain underserved populations with PAD.

Abstract
BACKGROUND Many children gained insurance with the 2014 Affordable Care Act's (ACA) Medicaid Expansion (ME), yet its impact on access to pediatric tertiary surgical care remains unknown. We examined the effect of ME on rates of elective, ambulatory surgery (EAS), especially among publicly-insured and ethnoracial-minority patients. METHODS Surgical patients ≤18 years between 2012 and 2018 were identified using the Pediatric Health Information System. Interrupted time series analyses were conducted to predict the monthly proportion of publicly-insured patients and EAS rates in ME and nonexpansion states. RESULTS 3,270,842 patients were included. Nonexpansion states demonstrated a 1.10% (p<0.05) increase in the proportion of publicly-insured patients at ACA implementation, which then plateaued. No immediate change was observed in ME states, but there was an annual 1.08% (p<0.01) decrease in subsequent years. Publicly-insured EAS rates decreased by 1.09% (p<0.01) in nonexpansion states; no change was observed in ME states. A 3.36% (p<0.01) increase in EAS rates was observed in nonexpansion and ME states. The gap in EAS rates increased between private and publicly-insured patients in nonexpansion, but not ME states. CONCLUSIONS Increased coverage for children in ME states was not associated with more access to tertiary pediatric surgical care; however, while nonexpansion states saw an increase in insurance-based disparities, ME states did not. Though insurance coverage is critical to access, other factors may be contributing to persistent disparities in access to pediatric surgical care.

Abstract
BACKGROUND & AIMS The Affordable Care Act provided the opportunity for states to expand Medicaid for low-income individuals. Not all states adopted Medicaid expansion, and the timing of adoption among expansion states varied. Prior studies have shown that Medicaid expansion improved mortality rates for several chronic conditions. Although there are data on the association between Medicaid expansion on insurance type among patients waitlisted for a liver transplant, there are no published data to date on its impact on liver disease-related mortality in the broader population. We therefore sought to evaluate the association between Medicaid expansion and state-level liver disease-related mortality using a quasi-experimental study design. METHODS We evaluated age-adjusted, state-level, liver disease-related mortality rates using the Centers for Disease Control and Prevention data. We fit multivariable linear regression models that accounted for sociodemographic, clinical, and access-to-care variables at the state level, and a difference-in-difference estimator to evaluate the association between Medicaid expansion and liver disease-related mortality. RESULTS In multivariable linear regression models, there was a significant association between Medicaid expansion and liver disease-related mortality (P = .02). Medicaid expansion was associated with 8.3 (95% CI, 1.6-15.1) fewer deaths from liver disease per 1,000,000 adult residents per year after Medicaid expansion compared with what would have been expected to occur if those states followed the same trajectory as nonexpansion states. The impact of Medicaid expansion translated to 870 fewer liver-related deaths per year in expansion states (4350 in the postexpansion study period from 2014 to 2018). CONCLUSIONS These data support the contention that Medicaid expansion has been associated with significantly decreased liver disease-related mortality. Universal Medicaid expansion could further decrease liver disease-related mortality in the United States.

Abstract
BACKGROUND Numerous studies have identified the association of socioeconomic factors with outcomes of cardiac surgical procedures. Most have focused on easily measured demographic factors or on socioeconomic characteristics of patients' 5-digit zip codes. The impact of socioeconomic information that is derived from smaller geographic regions has rarely been studied. METHODS The association of the Area Deprivation Index (ADI) with short-term mortality and readmissions was tested for patients undergoing percutaneous coronary intervention (PCI) in New York while adjusting for numerous patient risk factors, including race, ethnicity, and payer. Changes in hospitals' risk-adjusted outcomes and outlier status with the addition of socioeconomic factors were examined. RESULTS After adjustment, patients in the 2 most deprived ADI quintiles were more likely to experience in-hospital and 30-day mortality after PCI (adjusted odds ratios [95% confidence intervals] 1.39 [1.18-1.65] and 1.24 [1.03-1.49], respectively), than patients in the first quintile (least deprived). Also, patients in the second and fifth ADI quintiles had higher 30-day readmissions rates than patients in the first quintile (1.12 [1.01-1.25] and 1.17 [1.04-1.32], respectively). Medicare patients had higher mortality and readmission rates, Hispanics had lower mortality, and Medicaid patients had higher readmission rates. CONCLUSIONS Patients with the most deprived ADIs are more likely to experience short-term mortality and readmissions after PCI. Ethnicity and payer are significantly associated with adverse outcomes even after adjusting for ADI. This information should be considered when identifying patients who are at the highest risk for adverse events after PCI and when risk-adjusting hospital outcomes and assessing quality of care.

Abstract
BACKGROUND Despite living closer to high-performing centers, minority patients reportedly receive care at lower-quality hospitals. Investigating opportunities for improvement at minority-serving hospitals may help attenuate disparities in care among cardiothoracic surgery patients. We sought to investigate the relationship between hospital quality and failure-to-rescue (FTR). METHODS Over 451,000 cardiac surgery patients from 2000-2011 at minority-serving hospitals (MSH) were identified from the Nationwide Inpatient Sample. After stratifying patients by hospital mortality quartile, outcomes at poorly performing MSH were compared to those at high-performing MSH. Propensity-score matching was used for comparisons. RESULTS Though patients at poorly performing centers were more likely black, there were no significant differences in admission status (urgent vs elective), income, insurance, or risk before matching. There were no differences in comorbidities between low- and high-performing MSH including chronic lung disease, coagulopathy, hypertension, and renal failure. While complications remained similar across mortality quartiles (29%, 32%, 31%, 36% respectively; p<0.0001), FTR increased in a stepwise manner (5.4%, 8.7%, 11.2%, 15.5%; p<0.0001). The same was true after propensity-score matching - FTR nearly tripled in the highest-mortality centers (14.4% vs 5.3%; p<0.0001) while complications only increased 1.2-fold from 31.1% to 36.7% (p=0.0058). This finding persisted even when stratified by procedure type and by complication. CONCLUSIONS Improving timely management of complications after cardiac surgery may serve as a promising opportunity for increasing quality of care at MSH. When considering centralization of care in cardiac surgery, equal emphasis should be placed on collaboration between tertiary care centers and low-quality MSH to mitigate disparities in care.

J Surg Res 2021; 271:52-58. [PMID: 34837734 DOI: 10.1016/j.jss.2021.10.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 10/13/2021] [Accepted: 10/16/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Negative health effects of traveling longer distances for surgical services have been reported. Given the high complexity of multidisciplinary care required for management of Left Ventricular Assist Device (LVAD) implantation, only 4 of 18 centers in our state perform these operations. Given the limited access we hypothesized increased travel time would adversely affect postoperative outcomes and 30-d mortality. METHODS A statewide Society of Thoracic Surgeons database was queried to identify patients undergoing Heartmate II/III and HVAD implantation, and 725 patients were identified. Travel time was calculated by zip code. Patients were stratified into regional and distant groups by the upper quartile of travel time (1-h). Preoperative variables and outcomes were compared between the groups. Multivariate analysis was performed to evaluate the impact of travel time in risk-adjusted models of 30-d mortality. RESULTS Median patient travel time to their LVAD center in our state is 32 min (mean 53 ± 65 min, 46 ± 71 miles). Patients in the distant group (n = 191) had lower median incomes, higher self-pay status, higher rates of medical comorbid disease. Despite these differences there was no difference between the groups in ICU and/or hospital length of stay, readmission, postoperative complications, or 30-d mortality. Multivariate regression demonstrated insurance status, age, and prior surgery predicted 30-d mortality, but not travel time. CONCLUSIONS Despite only four centers in the state performing LVAD implantation, travel time was strongly associated with preoperative risk, and socioeconomic status but not postoperative outcomes or 30-d mortality. Therefore, increasing access should focus on insurance, and patient characteristics not travel time.

Abstract
PURPOSE During coronavirus disease-19 (COVID-19) pandemic, hospitals faced challenges which were different than previous years. The purpose this study was to report frequency of firearm injuries (FI) to head and neck during the COVID-19 pandemic. MATERIALS AND METHODS This cross-sectional study reviewed patients in the Trauma Registry at Grady Memorial Hospital (GMH) in Atlanta, GA. Patients were included if they sustained FI to head and neck, were listed in TR, and were treated at GMH. Patients were stratified according to date of injury into 1) before COVID-19 pandemic, (BC19) or 2) during initial 5 months of COVID-19 pandemic, (C19). Variables were patient demographics, illegal substance use, etiology, place of injury, distressed communities index, location of injury, Glasgow Coma scale on arrival, cardiopulmonary resuscitation in Emergency Department (ED), shock on admission, disposition from ED, length of stay, days on mechanical ventilation and discharge status. Descriptive, univariate, and bivariate analysis were completed. Chi square test was used for categorical variables. Statistical significance was P < .05. RESULTS There were 215 patients who met inclusion criteria. There were 96 patients (78 males) with a mean age of 31.5 years old during BC19. There were 119 patients (101 males) with a mean age 32.7 years old during C19. There was a 10.4% increase in FI to head and neck during COVID-19. Our data showed that alcohol use was associated with FI during C19 (P≤ .0001). FI to base of skull occurred 34.5% more often during C19 (P = .002). Cranial injuries occurred 26% more often during BC19 (P = .03). During BC19, 85.4% of the patients arrived alive to GMH, but only 16% arrived alive during C19 (P ≤ .0001). CONCLUSIONS There were more FI to head and neck during COVID-10 pandemic than during the previous time period.

Ann Thorac Surg 2021; 114:1637-1644. [PMID: 34678282 DOI: 10.1016/j.athoracsur.2021.09.025] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Revised: 08/02/2021] [Accepted: 09/04/2021] [Indexed: 11/01/2022]
Abstract
BACKGROUND Cardiac surgery utilization has increased after passage of the Affordable Care Act. This multi-state study examined whether changes in access after Medicaid Expansion (ME) have led to improved outcomes, overall and particularly among ethno-racial minorities. METHODS State Inpatient Databases were used to identify non-elderly adults (ages 18-64) who underwent coronary artery bypass grafting, aortic valve replacement, mitral valve replacement, or mitral valve repair in three expansion (Kentucky, New Jersey, Maryland) vs two non-expansion states (North Carolina, Florida) from 2012 to 2015. Linear and logistic Interrupted Time Series (ITS) were used with two-way interactions and adjusted for patient, hospital, and county-level factors to compare trends and instantaneous changes at the point of ME implementation (Q1 2014) for mortality, length of stay (LOS), and elective status. ITS models estimated expansion effect, overall and by race-ethnicity. RESULTS Analysis included 22,038 cardiac surgery patients from expansion states and 33,190 from non-expansion states. In expansion states, no significant trend changes were observed for mortality (OR 1.01, p=0.83) or LOS (β= -0.05, p=0.20), or elective surgery (OR 1.00, p=0.91). There were similar changes seen in non-expansion states. Among ethno-racial minorities, ME did not impact outcomes or elective status. CONCLUSIONS Despite an increase in cardiac surgery utilization following ME, outcomes remained unchanged in the early period after implementation, overall and among ethno-racial minorities. Future research is needed to confirm long-term trends and examine reasons behind this lack of improved outcomes.

Association of Medicaid Expansion with In-Hospital Outcomes After Abdominal Aortic Aneurysm Repair. J Surg Res 2021; 266:201-212. [PMID: 34022654 DOI: 10.1016/j.jss.2021.02.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 02/08/2021] [Accepted: 02/27/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVES Multiple studies have shown improved outcomes and higher utilization of care with the increase of insurance coverage. This study aims to assess whether Medicaid expansion (ME) has changed the utilization and outcomes of abdominal aortic aneurysm (AAA) repair in the United States. DESIGN Retrospective observational study. MATERIALS Data of patients undergoing AAA repair in the Vascular Quality Initiative (2010-2017). METHODS Interrupted time-series (ITS) analysis was utilized to evaluate changes in annual trends of postoperative outcomes after elective AAA repair before and after 2014. We also assessed if these trend changes were significant by comparing the changes in states which adopted ME in 2014 versus nonexpansion states (NME), and conducting a difference-in-difference analysis. Primary outcomes included in-hospital mortality and adverse events (bowel and leg ischemia, cardiac, renal, respiratory, stroke and return to the OR). RESULTS A total of 19,143 procedures were included (Endovascular: 85.8% and open: 14.2%), of which 40.9% were performed in ME States. Compared to preexpansion trends (P1), there was a 2% annual increase in elective AAA repair in ME states (P1: -1.8% versus P2: +0.2%, P< 0.01) with no significant change in NME (P1: +0.3% versus P2: +0.2%, P = 0.97). Among elective cases, annual trends in the use of EVAR increased by 2% in ME states (95% confidence interval (CI) = -0.1, 4.1, P = 0.06), compared to a 3% decrease in NME States [95%CI = -5.8, -0.6, P = 0.01) (PMEversusNME < 0.01]. There was no association between ME and in-hospital mortality. Nonetheless, it was associated with a decrease in the annual trends of in-hospital complications (ME: -1.4% (-2.1,-0.8) versus NME: +0.2% (-0.2, +0.8), P < 0.01). CONCLUSIONS While no association between ME and increased survival was noted in states which adopted ME, there was a significant increase of elective AAA cases and EVAR utilization and a decrease in in-hospital complications in ME States.

Abstract
BACKGROUND Insurance status has been strongly associated with both access to and outcomes of colon resection (CRS). Under the Affordable Care Act (ACA), individual states opted to participate in Medicaid expansion (ME) and adopt essential health benefits (EHB). METHODS We performed a quasi-experimental difference-in-differences (DID) analysis of 2012-2017 state-level inpatient claims with risk adjustment. We examined frequency of emergent presentation and in-hospital death. Subset analyses were performed by insurance type. RESULTS Among the 73,961 CRS patients, 49.6% were in a state with both ME and EHB, 34.7% presented emergently, and 2.0% died. Adoption of ME and EHB was associated with a significant, 24%, reduction in the likelihood of in-hospital mortality, and no significant change in emergent presentation for CRS. CONCLUSIONS The ACA's ME was strongly associated with a decrease in mortality following colon resection among Medicaid beneficiaries. These findings support the adoption of healthcare policies that improve access to insurance.

Abstract
Initially implemented in 2014 in some U.S. states, the Medicaid expansions under the Affordable Care Act (ACA) aimed to make health insurance coverage more accessible to the low-income population. This paper aims to quantify the impact of the ACA Medicaid expansions on insurance coverage among racial/ethnic minorities, immigrants, single mothers, veterans, and low-education whites-i.e., the sectors of the population identified with some of the highest healthcare needs. We focus on individuals 18-64 years of age earning 138% or less of the federal poverty level from the American Community Survey, 2010-2018 (n = 2,927,402). We use difference-in-differences (DD) and difference-in-difference-in-differences (DDD) approaches with propensity scores matched comparison groups to estimate pre-post ACA insurance coverage differences between individuals living in states that participated in the ACA Medicaid expansions and those living in non-participating states, and to estimate if such differences vary across subgroups. We find that insurance coverage rates increased for all subgroups; yet, the ACA benefits have not been evenly distributed across them. Low-education whites, non-Hispanic whites, females, and non-Hispanic Native Americans exhibited the highest improvements in insurance coverage. Our results contribute to the understanding of recent trends in racial and socioeconomic disparities in healthcare and the appropriate policy prescriptions to ameliorate them.

INQUIRY: THE JOURNAL OF HEALTH CARE ORGANIZATION, PROVISION, AND FINANCING 2021; 58:469580211062438.

Abstract
To examine whether rates of 30-day readmission after acute ischemic stroke
changed differentially between Medicaid expansion and non-expansion states, and
whether race/ethnicity moderated this change, we conducted a
difference-in-differences analysis using 6 state inpatient databases (AR, FL,
GA, MD, NM, and WA) from the Healthcare Cost and Utilization Project. Analysis
included all patients aged 19-64 hospitalized in 2012–2015 with a principal
diagnosis of ischemic stroke and a primary payer of Medicaid, self-pay, or no
charge, who resided in the state where admitted and were discharged alive
(N=28 330). No association was detected between Medicaid expansion and
readmission overall, but there was evidence of moderation by race/ethnicity. The
predicted probability of all-cause readmission among non-Hispanic White patients
rose an estimated 2.6 percentage points (or 39%) in expansion states but not in
non-expansion states, whereas it increased by 1.5 percentage points (or 23%) for
non-White and Hispanic patients in non-expansion states.
Therefore, Medicaid expansion was associated with a rise in readmission
probability that was 4.0 percentage points higher for non-Hispanic Whites
compared to other racial/ethnic groups, after adjustment for covariates. Similar
trends were observed when unplanned and potentially preventable readmissions
were isolated. Among low-income stroke survivors, we found evidence that 2 years
of Medicaid expansion promoted rehospitalization, but only for White patients.
Future studies should verify these findings over a longer follow-up period.

Abstract
BACKGROUND Medicaid expansion (ME) under the Affordable Care Act has reduced the number of uninsured patients, although its preferential effects on vulnerable populations have been mixed. This study examined whether ME preferentially improved cardiac surgery use by insurance strata, race, and income level. METHODS Non-elderly adults (aged 18-64 years) who underwent coronary artery bypass grafting, aortic valve replacement, mitral valve replacement, or mitral valve repair were identified in the State Inpatient Databases for 3 expansion states (Kentucky, New Jersey, and Maryland) and 2 non-expansion states (North Carolina and Florida) from 2012 to the third quarter of 2015. We used adjusted Poisson interrupted time series to determine the impact of ME on cardiac surgery use for Medicaid or uninsured (MCD/UIS) patients, racial and ethnic minorities, and individuals from low-income areas. RESULTS In expansion states, use among non-White MCD/UIS patients had a positive trend after ME (2.3%/quarter; P = .156), whereas use for White MCD/UIS patients fell (-1.7%/quarter; P = .117). In contrast, use among non-White MCD/UIS in non-expansion states decreased by 4.4% (P < .001) which was a greater decline than among White MCD/UIS patients (-1.8%/quarter; P = .057). There was no substantial effect of ME on cardiac surgery use for MCD/UIS patients from low- versus high-income areas. CONCLUSIONS These findings demonstrate that the use of cardiac surgical procedures was generally unchanged after ME; however, nonsignificant trend differences suggest a narrowing gap between vulnerable and non-vulnerable groups in ME states. These preliminary findings help describe the association of insurance coverage as a driver of cardiac surgery use among vulnerable patients.

Abstract
BACKGROUND High-volume centers improve outcomes in head and neck cancer (HNCA) reconstruction, yet it is unknown whether patients of all payer status benefit equally. METHODS We identified patients undergoing HNCA surgery between 2002 and 2015 using the National Inpatient Sample. Outcomes included receipt of care at high-volume centers, receipt of reconstruction, and post-operative complications. Multivariate regression analysis was stratified by payer status. RESULTS 37,442 patients received reconstruction out of 101,204 patients who underwent HNCA surgery (37.0%). Privately-insured and Medicaid patients had similar odds of receiving high-volume care (OR = 0.99, 95% CI = 0.87-1.11) and undergoing reconstruction (OR = 0.96, 95% CI = 0.86-1.05). Medicaid beneficiaries had higher odds of complication (OR = 1.36, 95% CI = 1.22-1.51). The discrepancy in complication odds was significant at low-volume (OR = 1.44, 95% CI = 1.12-1.84) and high-volume centers (OR = 1.30, 95% CI = 1.15-1.47). CONCLUSIONS Medicaid beneficiaries are as likely to receive care at high-volume centers and undergo reconstruction as privately-insured individuals. However, they have poorer outcomes than privately-insured individuals at both low- and high-volume centers.

Abstract
OBJECTIVE The purpose of this study was to assess the temporal trends in 30-day mortality by race group for patients undergoing coronary artery bypass grafting (CABG) between 2011 and 2018 and to investigate the effect of race and sex on postoperative outcomes after CABG. SUMMARY BACKGROUND DATA Cardiovascular diseases remain a leading cause of death in the United States with studies demonstrating increased morbidity and mortality for black and female patients undergoing surgery. In the post drug-eluting stent era, studies of racial disparities CABG are outdated. METHODS We performed a retrospective analysis of the Society for Thoracic Surgeons database for patients undergoing CABG between 2011 and 2018. Primary outcome was 30-day mortality. Secondary outcomes included postoperative length of stay, surgical site infection, sepsis, pneumonia, stroke, reoperation, reintervention, early extubation, and readmission. RESULTS The study population was comprised of 1,042,506 patients who underwent isolated CABG between 2011 and 2018. Among all races, Black patients had higher rates of preoperative comorbidities. Compared with White patients, Black patients had higher overall mortality (2.76% vs 2.19%, P < 0.001). On univariable regression, Black patients had higher rates of death, infection, pneumonia, and postoperative stroke compared to White patients. On multivariable regression, Black patients had higher odds of 30-day mortality compared to white patients [odds ratio (OR) = 1.11, 95% confidence interval (CI) 1.05-1.18]. Similarly, female patients had higher odds of death compared to males (OR = 1.26, 95% CI 1.21-1.30). CONCLUSIONS In the modern era, racial and sex disparities in mortality and postoperative morbidity after coronary bypass surgery persist with Black patients and female patients consistently experiencing worse outcomes than White male patients. Although there may be unknown or underappreciated biological mechanisms at play, future research should focus on socioeconomic, cultural, and multilevel factors.

Abstract
BACKGROUND Gallbladder disease frequently requires emergency general surgery (EGS). The Affordable Care Act (ACA) mandated health insurance coverage for all with the intent to improve access to care and decrease morbidity, mortality, and costs. We hypothesize that after the ACA open-enrollment in 2014 the number of EGS cholecystectomies decreased as access to care improved with a shift in EGS cholecystectomies to teaching institutions. METHODS A retrospective review of the National Inpatient Sample Database from 2012 to quarter 3 of 2015 was performed. Patients age 18-64, with a nonelective admission for gallbladder disease based on ICD-9 codes, were collected. Outcomes measured included cholecystectomy, complications, mortality, and wage index-adjusted costs. The effect of the ACA was determined by comparing preACA to postACA years. RESULTS 189,023 patients were identified. In the postACA period the payer distribution for admissions decreased for Self-pay (19.3% to 13.6%, P < 0.001), Medicaid increased (26.3% to 34.0%, P < 0.001) and Private insurance was unchanged (48.6% to 48.7%, P = 0.946). PostACA, admissions to teaching hospitals increased across all payer types, EGS cholecystectomies decreased, while complications increased, and mortality was unchanged. Median costs increased significantly for Medicaid and Private insurance while Self-pay was unchanged. Based on adjusted DID analyses for Insured compared to Self-pay patients, EGS cholecystectomies decreased (-2.7% versus -1.21%, P = 0.033) and median cost increased more rapidly (+$625 versus +$166, P = 0.017). CONCLUSIONS The ACA has changed EGS, shifting the majority of patients to teaching institutions despite insurance type and decreasing the need for EGS cholecystectomy. The trend toward higher complication rate with increased overall cost requires attention.

Abstract
We estimate the effect of the Affordable Care Act Medicaid expansion on county-level mortality in the first four years following expansion using restricted-access microdata covering all deaths in the United States. To adjust for pre-expansion differences in mortality rates between treatment and control, we use a propensity-score weighting model together with techniques from machine learning to match counties in expansion and non-expansion states. We find a reduction in all-cause mortality in ages 20 to 64 equaling 11.36 deaths per 100,000 individuals, a 3.6 percent decrease. This estimate is largely driven by reductions in mortality in counties with higher pre-expansion uninsured rates and for causes of death likely to be influenced by access to healthcare. A cost-benefit analysis shows that the improvement in welfare due to mortality responses may offset the entire net-of-transfers expenditure associated with the expansion.

Abstract
Importance Medicaid expansion under the Patient Protection and Affordable Care Act led to one of the largest gains in health insurance coverage for nonelderly adults in the United States. However, its association with cardiovascular mortality is unclear. Objective To investigate the association of Medicaid expansion with cardiovascular mortality rates in middle-aged adults. Design, Setting, and Participants This study used a longitudinal, observational design, using a difference-in-differences approach with county-level data from counties in 48 states (excluding Massachusetts and Wisconsin) and Washington, DC, from 2010 to 2016. Adults aged 45 to 64 years were included. Data were analyzed from November 2018 to January 2019. Exposures Residence in a Medicaid expansion state. Main Outcomes and Measures Difference-in-differences of annual, age-adjusted cardiovascular mortality rates from before Medicaid expansion to after expansion. Results As of 2016, 29 states and Washington, DC, had expanded Medicaid eligibility, while 19 states had not. Compared with counties in Medicaid nonexpansion states, counties in expansion states had a greater decrease in the percentage of uninsured residents at all income levels (mean [SD], 7.3% [3.2%] vs 5.6% [2.7%]; P < .001) and in low income strata (19.8% [5.5%] vs 13.5% [3.9%]; P < .001) between 2010 and 2016. Counties in expansion states had a smaller change in cardiovascular mortality rates after expansion (146.5 [95% CI, 132.4-160.7] to 146.4 [95% CI, 131.9-161.0] deaths per 100 000 residents per year) than counties in nonexpansion states did (176.3 [95% CI, 154.2-198.5] to 180.9 [95% CI, 158.0-203.8] deaths per 100 000 residents per year). After accounting for demographic, clinical, and economic differences, counties in expansion states had 4.3 (95% CI, 1.8-6.9) fewer deaths per 100 000 residents per year from cardiovascular causes after Medicaid expansion than if they had followed the same trends as counties in nonexpansion states. Conclusions and Relevance Counties in states that expanded Medicaid had a significantly smaller increase in cardiovascular mortality rates among middle-aged adults after expansion compared with counties in states that did not expand Medicaid. These findings suggest that recent Medicaid expansion was associated with lower cardiovascular mortality in middle-aged adults and may be of consideration as further expansion of Medicaid is debated.

Effects of Medicaid expansion on access, treatment and outcomes for patients with acute myocardial infarction. PLoS One 2020; 15:e0232097.

Abstract
INTRODUCTION Uninsured patients have decreased access to care, lower rates of percutaneous coronary intervention (PCI), and worse outcomes after acute myocardial infarction (AMI). The aim of this study was to determine whether expanding insurance coverage through the Affordable Care Act's expansion of Medicaid eligibility affected access to PCI hospitals, rates of PCI, 30-day readmissions, and in-hospital mortality after AMI. METHODS Quasi-experimental, difference-in-differences analysis of Medicaid and uninsured patients with acute myocardial infarction in California, which expanded Medicaid through the Affordable Care Act, and Florida, which did not, from 2010-2015. This study accounts for the early expansion of Medicaid in certain California counties that began as early as July 2011. Main outcomes included rates of admission to PCI hospitals, rates of transfer for patients who initially presented to non-PCI hospitals, rates of PCI, rates of early PCI defined as within 48 hours of hospital admission, in-hospital mortality, and 30-day readmission. RESULTS 55,991 hospital admissions between 2010-2015 met inclusion criteria. Of these, 32,540 were in California, which expanded Medicaid, and 23,451 were in Florida, which did not. 30-day readmission rates after AMI decreased by an absolute difference of 1.22 percentage points after the Medicaid expansion (95% CI -2.14 to -0.30, P < 0.01). This represented a relative decrease in readmission rates of 9.5% after AMI. No relationship between the Medicaid expansion and admission to PCI hospitals, transfer to PCI hospitals, rates of PCI, rates of early PCI, or in-hospital mortality were observed. CONCLUSIONS Hospital readmissions decreased by 9.5% after the Affordable Care Act expanded Medicaid eligibility, although there was no association found between Medicaid expansion and access to PCI hospitals or treatment with PCI. Better understanding the ways that Medicaid expansion might affect care for vulnerable populations with AMI is important for policymakers considering whether to expand Medicaid eligibility in their state.

Abstract
BACKGROUND The Affordable Care Act (ACA) Medicaid expansion increased Medicaid eligibility such that all adults with an income level up to 138% of the federal poverty threshold in 2014 qualified for Medicaid benefits. Prior studies have shown that the ACA Medicaid expansion was associated with increased access to care. The impact of the ACA Medicaid expansion on patients undergoing complex care for major vascular pathology has not been evaluated. METHODS The Healthcare Cost and Utilization Project State Inpatient Database was used to identify patients undergoing care for major vascular pathology in 6 states from 2010 to 2014. The analysis cohort included adult patients between the ages of 18 and 64 years who underwent a nonemergent surgical procedure for an abdominal aortic aneurysm, thoracic aortic aneurysm, carotid artery stenosis, peripheral vascular disease, or chronic kidney disease. Poisson regression was used to determine the incidence rate ratios (IRRs). RESULTS There were a total of 83,960 patients in the study cohort. Compared with nonexpansion states, inpatient admissions for Medicaid patients with an abdominal or thoracic aneurysm and carotid stenosis diagnosis increased significantly (IRR, 1.20, 1.27, 1.06, respectively; P < 0.05) in states that expanded Medicaid. Vascular-related surgeries increased for carotid endarterectomy, lower extremity revascularization, lower extremity amputation, and arteriovenous fistula in expansion states (IRR, 1.24, 1.10, 1.11, 1.16, respectively; P < 0.05) compared with nonexpansion states. CONCLUSIONS In states that expanded Medicaid coverage under the ACA, the rate of vascular-related surgeries and admissions for Medicaid patients increased. We conclude that expanding insurance coverage results in enhanced access to vascular surgery.

Abstract
OBJECTIVE Several studies have demonstrated that socioeconomic factors may affect surgical outcomes. Analyses in vascular surgery have been limited by the availability of individual or community-level socioeconomic data. We sought to determine whether the Distressed Communities Index (DCI), a composite socioeconomic ranking by ZIP code, could predict short- and long-term outcomes for patients with peripheral artery disease. METHODS All Virginia Quality Initiative patients (n = 2578) undergoing infrainguinal bypass (2011-2017) within a region of 17 centers were assigned a composite DCI score. The score was developed by the Economic Innovation Group and is normally distributed from 0 (no distress) to 100 (severe distress) based on measures of community unemployment, education level, poverty rate, median income, business growth, and housing vacancies. Severely distressed communities were defined as the top quartile DCI (>75). Hierarchical regression assessed short-term outcomes, and time-to-event analyses assessed long-term results. RESULTS Infrainguinal bypass patients in this study came from disproportionately distressed communities, with 29% of patients living within the highest distress DCI quartile (P < .0001), with high variability by hospital (DCI range, 12-67). These patients from severely distressed areas were younger, more likely to smoke, and disproportionately African American and had higher rates of medical comorbidities (all P < .05). Whereas patients from severely distressed communities had an equivalent rate of 30-day major adverse cardiac and cerebrovascular events (5% vs 4%; P = .86), they had increased rates of major adverse limb events (MALEs) at 13% vs 10% (P = .03). This trend persisted in the long term, with higher 1-year estimates of MALEs (21% vs 17%; P = .01) as well as the components of amputation (17% vs 12%; P = .006) and thrombectomy (11% vs 6%; P = .002). Patients with high socioeconomic distress also had higher rates of occlusion (17% vs 11%; P = .003). CONCLUSIONS In this study, patients from severely distressed communities were found to have increased rates of MALEs, an association that persisted long term. Mitigating risk associated with socioeconomic determinants of health has the potential to improve outcomes for patients with peripheral artery disease.

Abstract
The impact of the Patient Protection and Affordable Care Act (PPACA) on children's access to surgical care is not well-defined. Our objective was to describe the early impact of PPACA on children's surgical care before and after Medicaid expansion in 2014. We compared pediatric and young adult surgical outcomes in 2013 and 2014 in Medicaid expansion and nonexpansion states; young adults were included as a control group. From 4 states, 1 597 708 encounters met all inclusion criteria. Comparing expansion to nonexpansion states, modest increases were noted in elective instead of urgent/emergent admissions; in ambulatory instead of inpatient surgeries; in inpatient length of stays; in discharges to home instead of other inpatient care facilities; and in charges for inpatient admissions. A modest decrease of -1.1% was noted in ambulatory admission charges. Overall, we conclude that Medicaid expansion likely increased children's access to surgical care, resulting in improved delivery and slightly reduced charges.

Abstract
BACKGROUND Although Medicaid expansion has improved access to primary care services, its impact on surgical specialty utilization remains unclear. The aim of this study is to determine whether Medicaid expansion is associated with increased utilization rates of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Illinois (which expanded Medicaid) relative to Missouri (which did not expand Medicaid). METHODS Using administrative data sources, we analyzed 374,877 total hospitalizations (236,333 in Illinois and 138,544 in Missouri) for THA/TKA from 2011 to 2016 (Illinois' Medicaid expansion date: January 1, 2014). RESULTS The percentage of THA/TKA funded by Medicaid in Illinois was 2.4% in 2013 and 3.9% in 2016 (Missouri 2013: 2.7%; 2016: 2.6%). A difference-in-difference analysis (adjusted for patient age and gender, county-level Area Deprivation Index, and number of orthopedic surgeons) demonstrated a statistically significant increase in Medicaid-funded THA/TKA in Illinois in 2016 compared to 2013 (P = .012). CONCLUSION Our study demonstrates that Medicaid expansion in Illinois was associated with increased utilization of THA and TKA. Further study is needed to understand the impact of Medicaid expansion in other states and for other procedures.

Socioeconomic Distressed Communities Index Predicts Risk-Adjusted Mortality After Cardiac Surgery. Ann Thorac Surg 2019; 107:1706-1712.

Abstract
BACKGROUND The effects of socioeconomic factors other than insurance status and race on outcomes after cardiac operations are not well understood. We hypothesized that the Distressed Communities Index (DCI), a comprehensive socioeconomic ranking by zip code, would predict operative mortality after coronary artery bypass grafting (CABG). METHODS All patients who underwent isolated CABG (2010 to 2017) in the Virginia Cardiac Services Quality Initiative database were analyzed. The DCI accounts for unemployment, education level, poverty rate, median income, business growth, and housing vacancies, with scores ranging from 0 (no distress) to 100 (severe distress). Patients were stratified by DCI quartiles (I: 0 to 24.9, II: 25 to 49.9, III: 50 to 74.9, IV: 75 to 100) and compared. Hierarchical linear regression modeled the association between the DCI and mortality. RESULTS A total of 19,756 CABG patients were analyzed, with mean predicted risk of mortality of 2.0% ± 3.5%. Higher DCI scores were associated with increasing predicted risk of mortality. Overall operative mortality was 2.1% (n = 424) and increased with increasing DCI quartile (I: 1.6% [n = 95], II: 2.1% [n = 77], III: 2.4% [n = 114], IV: 2.6% [n = 138]; p = 0.0009). The observed-to-expected ratio for mortality increased as level of socioeconomic distress increased. After risk adjustment for The Society of Thoracic Surgeons predicted risk of mortality, year of surgical procedure, and hospital, the DCI remained predictive of operative mortality after CABG (odds ratio, 1.14 for each 25-point increase in DCI; 95% confidence interval 1.04 to 1.26; p = 0.007). CONCLUSIONS The DCI independently predicts risk-adjusted operative mortality after CABG. Socioeconomic status, although not part of traditional risk calculators, should be considered when building risk models, evaluating resource utilization, and comparing hospitals.

Abstract
BACKGROUND The Affordable Care Act (ACA) dramatically changed the healthcare system in the United States. This study aims to analyze the impact of the ACA on general surgery clinic visits and resultant procedures. METHODS A retrospective review was conducted on new patients who presented to the elective general surgery clinic at an academic medical center between Jan. 1, 2012 and Dec. 31, 2015. Based on the open enrollment start date of Jan.1, 2014 patients were divided into pre-ACA and post-ACA periods. Data on demographics, type of insurance, missed appointments, and elective surgical procedures performed were collected. RESULTS Medi-Cal insurance coverage increased post-ACA from 20.9% to 56.7%, p < 0.001; self-pay status went from 9.8% to 0%. There were 296 (35.4%) surgical procedures performed pre-ACA and 347 (37.1%) post-ACA (p = 0.445). Missed clinic visits decreased after implementation of the ACA, with 26.8% no-shows pre-ACA and 20.7% no-shows post-ACA (p = 0.003). CONCLUSION The ACA had a profound impact on the general surgery clinic with fewer uninsured patients, fewer no-shows and a modest increase in the number of procedures performed. SUMMARY In 2014 the Affordable Care Act mandate was implemented. This legislation impacted healthcare by significantly decreasing the number of uninsured patients and increasing overall volume in one general surgery clinic.

Abstract
BACKGROUND Health insurance coverage changes for many patients after liver transplantation, but the implications of this change on long-term outcomes are unclear. AIMS To assess post-transplant patient and graft survival according to change in insurance coverage within 1 year of transplantation. METHODS We queried the United Network for Organ Sharing for patients between ages 18-64 years undergoing liver transplantation in 2002-2016. Patients surviving > 1 year were categorized by insurance coverage at transplantation and the 1-year transplant anniversary. Multivariable Cox regression characterized the association between coverage pattern and long-term patient or graft survival. RESULTS Among 34,487 patients in the analysis, insurance coverage patterns included continuous private coverage (58%), continuous public coverage (29%), private to public transition (8%) and public to private transition (4%). In multivariable analysis of patient survival, continuous public insurance (HR 1.29, CI 1.22, 1.37, p < 0.001), private to public transition (HR 1.17, CI 1.07, 1.28, p < 0.001), and public to private transition (HR 1.14, CI 1.00, 1.29, p = 0.044), were associated with greater mortality hazard, compared to continuous private coverage. After disaggregating public coverage by source, mortality hazard was highest for patients transitioning from private insurance to Medicaid (HR vs. continuous private coverage = 1.32; 95% CI 1.14, 1.52; p < 0.001). Similar differences by insurance category were found for death-censored graft failure. CONCLUSION Post-transplant transition to public insurance coverage is associated with higher risk of adverse outcomes when compared to retaining private coverage.

Eslami MH, Reitz KM, Rybin DV, Doros G, Farber A. Improved access to health care in Massachusetts after 2006 Massachusetts Healthcare Reform Law is associated with a significant decrease in mortality among vascular surgery patients. J Vasc Surg 2018; 68:1193-1202.e1. [PMID: 29615354 DOI: 10.1016/j.jvs.2017.12.066] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Accepted: 12/18/2017] [Indexed: 11/18/2022]
Abstract
BACKGROUND Access to medical care, by adequate insurance coverage, has a direct impact on outcomes for patients undergoing vascular procedures. We evaluated in-hospital mortality for patients undergoing index vascular procedures before and after the Massachusetts Healthcare Reform Law (MHRL) in 2006, which mandated insurance for all Massachusetts residents, both in Massachusetts and throughout the United States. METHODS The National Inpatient Sample was queried to identify patients undergoing interventions for peripheral arterial disease, carotid artery stenosis, and abdominal aortic aneurysms based on International Classification of Diseases, Ninth Revision, Clinical Modification procedural and diagnostic codes. The cohort was then divided into patients treated within Massachusetts (MA) and non-Massachusetts (NMA) hospitals. Two time intervals were examined: before (2003-2006, P1) and after the MHRL (2007-2011, P2). The primary outcome of interest included in-hospital mortality. Patients in MA and NMA hospitals were described in terms of demographics and presentation by time interval (P2 vs P1) compared using χ2 and t-tests. Weighted logistic regression with term modeling change in the odds ratio (OR) for P2 was performed to test and to estimate trends in mortality. Time (year of procedure) and region interactions were investigated by inclusion of time-region interactions in our analyses. Subgroup analysis was performed for P2 vs P1 among nonwhite, nonelderly, and low-income patients. RESULTS We identified 306,438 patients who underwent repair of abdominal aortic aneurysm, lower extremity bypass, or carotid endarterectomy in MA and NMA hospitals. MA hospital patients had an increase in both Medicaid and private insurance status after the MHRL (P1 = 2.6% and 21% vs P2 = 3.3% and 21.7%, respectively; P = .034). In-hospital mortality trended down for all groups across the entire study. In comparing P2 vs P1 trends, MA hospital odds of mortality per year was lowered by 26% (OR, 0.74; 95% confidence interval [CI], 0.56-0.99; P = .042) not seen in NMA hospitals (OR, 1.03; 95% CI, 0.97-1.09; P = .405). Time and region interaction terms indicated significant time trend difference in both unadjusted (P = .031) and adjusted (P = .033) analysis in MA hospitals not observed in NMA hospitals. This pattern continued when the samples were stratified by procedure. Patients undergoing vascular procedures in MA hospitals had a significantly lowered OR of mortality, with fewer patients presenting at late disease stages in P2 vs P1. Nonelderly patients in Massachusetts, who benefit from the Medicaid expansion provided by the MHRL, had a profound 92% drop in odds of mortality in P2 vs P1 (OR, 0.08; 95% CI, 0.010-0.641; P = .017) compared with the 14% drop in NMA (OR, 0.86; 95% CI, 0.709-1.032; P = .103). CONCLUSIONS The 2006 MHRL is associated with a decrease in mortality for patients undergoing index vascular surgery procedures in MA compared with NMA hospitals. This study suggests that governmental policy may play a key role in positively affecting the outcomes for patients.
