Background: Cardiac surgery utilization has increased after passage of the Affordable Care Act. This multistate study examined whether changes in access after Medicaid expansion (ME) have led to improved outcomes, overall and particularly among ethnoracial minorities., Methods: State Inpatient Databases were used to identify nonelderly adults (ages 18-64 years) who underwent coronary artery bypass grafting, aortic valve replacement, mitral valve replacement, or mitral valve repair in 3 expansion (Kentucky, New Jersey, Maryland) vs 2 nonexpansion states (North Carolina, Florida) from 2012 to 2015. Linear and logistic interrupted time series were used with 2-way interactions and adjusted for patient-level, hospital-level, and county-level factors to compare trends and instantaneous changes at the point of ME implementation (quarter 1 of 2014) for mortality, length of stay, and elective status. Interrupted time series models estimated expansion effect, overall and by race-ethnicity., Results: Analysis included 22 038 cardiac surgery patients from expansion states and 33 190 from nonexpansion states. In expansion states, no significant trend changes were observed for mortality (odds ratio, 1.01; P = .83) or length of stay (β = -0.05, P = .20), or for elective surgery (odds ratio, 1.00; P = .91). There were similar changes seen in nonexpansion states. Among ethnoracial minorities, ME did not impact outcomes or elective status., Conclusions: Despite an increase in cardiac surgery utilization after ME, outcomes remained unchanged in the early period after implementation, overall and among ethnoracial minorities. Future research is needed to confirm long-term trends and examine reasons behind this lack of improved outcomes., (Copyright © 2022 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Background: While pre-Affordable Care Act expansions in Medicaid eligibility led to increased utilization of elective inpatient procedures, the impact of the Affordable Care Act on such preference-sensitive procedures (also known as discretionary procedures) versus time-sensitive non-discretionary procedures remains unknown. As such, we performed a hospital-level quasi-experimental evaluation to measure the differential effects of the Affordable Care Act's Medicaid expansion on utilization of discretionary procedures versus non-discretionary procedures., Methods: The State Inpatient Database (2012-2014) yielded 476 hospitals providing selected discretionary procedures or non-discretionary procedures performed on 288,446 non-elderly, adult patients across 3 expansion states and 2 non-expansion control states. Discretionary procedures included non-emergent total knee and hip arthroplasty, while non-discretionary procedures included nine cancer surgeries. Mixed Poisson interrupted time series analyses were performed to determine the impact of the Affordable Care Act's Medicaid expansion on the number of discretionary procedures versus non-discretionary procedures provided among non-privately insured patients (Medicaid and uninsured patients) and privately insured patients., Results: Analysis of the number of non-privately insured procedures showed an increase in discretionary procedures of +15.1% (IRR 1.15, 95% CI:1.11-1.19) vs -4.0% (IRR 0.96, 95% CI:0.94-0.99) and non-discretionary procedures of +4.1% (IRR 1.04, 95% CI:1.0-1.1) vs -5.3% (IRR 0.95, 95% CI:0.93-0.97) in expansion states compared to non-expansion states, respectively. Analysis of privately insured procedures showed no statistically meaningful change in discretionary procedures or non-discretionary procedures in either expansion or non-expansion states., Conclusion: In this multi-state evaluation, the Affordable Care Act's Medicaid expansion preferentially increased utilization of discretionary procedures versus non-discretionary procedures in expansion states compared to non-expansion states among non-privately insured patients. These preliminary findings suggest that increased Medicaid coverage may have contributed to the increased use of inpatient surgery for discretionary procedures., (Copyright © 2018 Elsevier Inc.

Background: The Affordable Care Act (ACA)'s Medicaid expansion has increased access to surgical care overall. Whether it was associated with reduced disparities in use of regionalized surgery at high-volume hospitals (HVH) remains unknown. Quasi-experimental evaluations of this expansion were performed to examine the use of regionalized surgery at HVH among racial/ethnic minorities and low-income populations., Study Design: Data from State Inpatient Databases (2012 to 2014), the American Hospital Association Annual Survey Database, and the Area Resource File from Health Resources and Services Administration, were used to examine 166,558 nonelderly (ages 18 to 64) adults at 468 hospitals, who underwent 1 of 4 regionalized surgical procedures in 3 expansion (KY, MD, NJ) and 2 nonexpansion states (NC, FL). Thresholds of HVH were defined using the top quintile of visits per year. Interrupted time series were performed to measure the impact of expansion on use rates of regionalized surgery at HVH overall, by race/ethnicity, and by income., Results: Overall, ACA's expansion was not associated with accelerated use rates of regionalized surgical procedures at HVH (odds ratio [OR] 1.016, p = 0.297). Disparities in use of regionalized surgical procedures at HVH among ethnic/racial minorities and low-income populations were unchanged; minority vs white (OR 1.034 p = 0.100); low-income vs high-income (OR 1.034, p = 0.122)., Conclusions: Early findings from ACA's Medicaid expansion revealed no impact on the use rates of regionalized surgery at HVH overall or on disparities among vulnerable populations. Although these results need ongoing evaluation, they highlight potential limitations in ACA's expansion in reducing disparities in use of regionalized surgical care., (Copyright © 2018.

Background: The Affordable Care Act's Medicaid expansion has been heavily debated due to skepticism about Medicaid's ability to provide high-quality care. Particularly, little is known about whether Medicaid expansion improves access to surgical cancer care at high-quality hospitals. To address this question, we examined the effects of the 2001 New York Medicaid expansion, the largest in the pre-Affordable Care Act era, on this disparity measure., Study Design: We identified 67,685 nonelderly adults from the New York State Inpatient Database who underwent select cancer resections. High-quality hospitals were defined as high-volume or low-mortality hospitals. Disparity was defined as model-adjusted difference in percentage of patients receiving operations at high-quality hospitals by insurance type (Medicaid/uninsured vs privately insured) or by race (African American vs white). Levels of disparity were calculated quarterly for each comparison pair and then analyzed using interrupted time series to evaluate the impact of Medicaid expansion., Results: Disparity in access to high-volume hospitals by insurance type was reduced by 0.97 percentage points per quarter after Medicaid expansion (p < 0.0001). Medicaid/uninsured beneficiaries had similar access to low-mortality hospitals as the privately insured; no significant change was detected around expansion. Conversely, racial disparity increased by 0.87 percentage points per quarter (p < 0.0001) in access to high-volume hospitals and by 0.48 percentage points per quarter (p = 0.005) in access to low-mortality hospitals after Medicaid expansion., Conclusions: Pre-Affordable Care Act Medicaid expansion reduced the disparity in access to surgical cancer care at high-volume hospitals by payer. However, it was associated with increased racial disparity in access to high-quality hospitals. Addressing racial barriers in access to high-quality hospitals should be prioritized., (Copyright © 2017 American College of Surgeons. Published by Elsevier Inc. All rights reserved.)

Background: Although the Affordable Care Act (ACA) expanded Medicaid access, it is unknown whether this has led to greater access to complex surgical care. Evidence on the effect of Medicaid expansion on access to surgical cancer care, a proxy for complex care, is sparse. Using New York's 2001 statewide Medicaid expansion as a natural experiment, we investigated how expansion affected use of surgical cancer care among beneficiaries overall and among racial minorities., Study Design: From the New York State Inpatient Database (1997 to 2006), we identified 67,685 nonelderly adults (18 to 64 years of age) who underwent cancer surgery. Estimated effects of 2001 Medicaid expansion on access were measured on payer mix, overall use of surgical cancer care, and percent use by racial/ethnic minorities. Measures were calculated quarterly, adjusted for covariates when appropriate, and then analyzed using interrupted time series., Results: The proportion of cancer operations paid by Medicaid increased from 8.9% to 15.1% in the 5 years after the expansion. The percentage of uninsured patients dropped by 21.3% immediately after the expansion (p = 0.01). Although the expansion was associated with a 24-case/year increase in the net Medicaid case volume (p < 0.0001), the overall all-payer net case volume remained unchanged. In addition, the adjusted percentage of ethnic minorities among Medicaid recipients of cancer surgery was unaffected by the expansion., Conclusions: Pre-ACA Medicaid expansion did not increase the overall use or change the racial composition of beneficiaries of surgical cancer care. However, it successfully shifted the financial burden away from patient/hospital to Medicaid. These results might suggest similar effects in the post-ACA Medicaid expansion., (Copyright © 2017 American College of Surgeons. Published by Elsevier Inc. All rights reserved.)

Background: Medicaid beneficiaries do not have equal access to high-volume centers for complex surgical procedures. We hypothesize there is a large Medicaid Gap between those receiving emergency general vs complex surgery at the same hospital., Methods: Using the Nationwide Inpatient Sample, 1998 to 2010, we identified high-volume pancreatectomy hospitals. We then compared the percentage of Medicaid patients receiving appendectomies vs pancreatectomies at these hospitals. Hospital characteristics associated with increased Medicaid Gap were evaluated using generalized estimating equation models., Results: A total of 602 hospital-years of data from 289 high-volume pancreatectomy hospitals were included. Median percentages of Medicaid appendectomies and pancreatectomies were 12.1% (interquartile range: 5.8% to 19.8%) and 6.7% (interquartile range: 0% to 15.4%), respectively. Hospitals that performed greater than or equal to 40 pancreatic resections per year had higher odds of having significant Medicaid Gap (odds ratio 2.3, 95% confidence interval 1.1 to 5.0)., Conclusions: Gaps exist between the percentages of Medicaid patients receiving emergency general surgery vs more complex surgical care at the same hospital and may be exaggerated in hospitals with very high volume of complex elective surgeries., (Copyright © 2016 Elsevier Inc.

Continuous-flow left ventricular assist device (LVAD) implantation is a payor sensitive procedure influenced by preoperative comorbidities and social factors. Whether expansion in insurance coverage will further influence device utilization is unknown. This study sought to assess the effects of Medicaid expansion on vulnerable populations (namely racial–ethnic minorities and those with low-income status) undergoing continuous-flow LVAD implantation after the enactment of the 2014 Affordable Care Act (ACA). Data from the 2012 to Q3 2015 State Inpatient Database were used to examine a cohort of 624 nonelderly adults (aged 18-64 y) who were given a continuous-flow LVAD in three expansion states (Kentucky, New Jersey, and Maryland) and two nonexpansion states (North Carolina and Florida). The cohort excluded patients who had a heart transplant, heart–lung transplant, or noncontinuous-flow LVAD. Poisson Interrupted Time Series was used with three-way interactions and change of slope and intercept parameters at 2014 to determine the impact of the ACA expansion on utilization of continuous-flow LVAD by race and insurance strata. Poisson Interrupted Time Series models show that within expansion states, the population of Medicaid and uninsured patients saw an increase in the utilization of LVAD's immediately after ACA expansion, from 2.8 in Q4 2013 to 9.83 Q1 2014 (incidence rate ratio [IRR] 5.26, P = 0.02). Utilization eventually declined to pre-ACA levels, however, ending with 3.04 LVADs in Q3 2015 (IRR 0.84, 95% confidence interval 0.58-1.20). Models testing for racial effect showed no statistically preferential or disparate effects (immediate effect IRR 1.608, P = 0.506; marginal effect IRR 0.897, P = 0.512). These findings show that despite expanded insurance coverage, the utilization of continuous-flow LVADs was not increased in nonelderly racial and ethnic minorities following the ACA Medicaid expansion. Although these findings are preliminary and require further long-term evaluation, they suggest that insurance coverage alone does not play a significant role in increased utilization of continuous-flow LVAD. These findings point toward the importance of further exploring social, medical, and hospital drivers of these disparities. [ABSTRACT FROM AUTHOR]

Background: Penalties from the Hospital Readmission Reduction Program can push financially strained, vulnerable patient-serving hospitals into additional hardship. In this study, we quantified the association between vulnerable hospitals and readmissions and examined the respective contributions of patient- and hospital-related factors.Methods: A total of 110,857 patients who underwent major cancer operations were identified from the 2004-2011 State Inpatient Database of California. Vulnerable hospitals were defined as either self-identified safety net hospitals (SNHs) or hospitals with a high percentage of Medicaid patients (high Medicaid hospitals [HMHs]). We used multivariable logistic regression to determine the association between vulnerable hospitals and readmission. Patient and hospital contributions to the elevation in odds of readmission were assessed by comparing estimates from models with different subsets of predictors.Results: Of the 355 hospitals, 13 were SNHs and 31 were HMHs. After adjusting for Hospital Readmission Reduction Program variables, SNHs had higher 30-day (odds ratio [OR] = 1.32; 95% CI, 1.18-1.47), 90-day (OR = 1.28; 95% CI, 1.18-1.38), and repeated readmissions (OR = 1.33; 95% CI, 1.18-1.49); HMHs also had higher 30-day (OR = 1.18; 95% CI, 1.05-1.32), 90-day (OR = 1.28; 95% CI, 1.16-1.42), and repeated readmissions (OR = 1.24; 95% CI, 1.01-1.54). Compared with patient characteristics, hospital factors accounted for a larger proportion of the increase in odds of readmission among SNHs (60% to 93% vs 24% to 39%), but a smaller proportion among HMHs (9% to 15% vs 60% to 115%).Conclusions: Vulnerable status of hospitals is associated with higher readmission rates after major cancer surgery. These findings reinforce the call to account for socioeconomic variables in risk adjustments for hospitals who serve a disproportionate share of disadvantaged patients. [ABSTRACT FROM AUTHOR]
