6525 Background: Inadequate access to healthcare services is associated with worse outcomes. Disparities in access to cancer care are more frequently seen among racial/ethnic minorities, uninsured patients, and those with low socioeconomic status. A provision in the Affordable Care Act called for expansion of Medicaid eligibility in order to cover more low-income Americans. In this study, we evaluate the impact of Medicaid expansion in 2-year mortality among metastatic BC patients according to race. Methods: Women (aged 40-64) diagnosed with metastatic BC (stage IV de novo) between 01/01/2010 and 12/31/2015 and residing in states that underwent Medicaid expansion in 01/2014 were identified in the National Cancer Database. For comparison purposes, 2010-2013 was considered the pre-expansion period and 2014-2015 the post-expansion period. We calculated 2-year mortality difference-in-difference (DID) estimates between White and non-White patients using multivariable linear regression models. Results are presented as adjusted differences (in % points) between groups in the pre- and post-expansion periods and as adjusted DID with 95%CI. Covariates included age, comorbidity, BC subtype, insurance type, transfer of care, distance to hospital, region, residence area, education, income quartile, facility type and facility volume. In addition, overall survival (OS) was evaluated in pre- and post-expansion periods via Kaplan-Meier method and Cox proportional hazards models; results are presented as 2-year OS estimates, hazard ratios (HRs), and 95% CIs. Results: Among 7,675 patients included, 4,942 were diagnosed in the pre- and 2,733 in the post-expansion period. We observed a reduction in 2-year mortality rates in both groups according to Medicaid expansion. Among Whites 2-year mortality decreased from 42.5% to 38.7% and among non-Whites from 45.4% to 36.4%, resulting in an adjusted DID of -5.2% (95%CI -9.8 to -0.6, p = 0.027). A greater reduction in 2-year mortality was observed among non-Whites in a sub-analysis of patients who resided in the poorest quartile (n = 1372), with an adjusted DID of -14.6% (95%CI -24.8 to -4.4, p = 0.005). In the multivariable Cox model, during the pre-expansion period there was an increased risk of death for non-Whites compared to Whites (HR 1.14, 95% CI 1.03 to 1.26, P = 0.04), however no differences were seen in the post-expansion period between the two groups (HR 0.93, 95% CI 0.80 to 1.07, P = 0.31). Conclusions: Medicaid expansion reduced racial disparities by decreasing the 2-year mortality of non-White patients with metastatic breast cancer and reducing the gap when compared to Whites. These results highlight the positive impact of policies aimed at improving equity and increasing access to health care.

The Impact

OBJECTIVE The Affordable Care Act expanded Medicaid eligibility in many states, improving access to some forms of elective healthcare in the United States. Whether this effort increased access to elective spine surgical care is unknown. This study’s objective was to evaluate the impact of Medicaid expansion under the Affordable Care Act on the volume and payer mix of elective spine surgery in the United States. METHODS This study evaluated elective spine surgical procedures performed from 2011 to 2016 and included in the all-payer State Inpatient Databases of 10 states that expanded Medicaid access in 2014, as well as 4 states that did not expand Medicaid access. Adult patients aged 18–64 years who underwent elective spine surgery were included. The authors used a quasi-experimental difference-in-difference design to evaluate the impact of Medicaid expansion on hospital procedure volume and payer mix, independent of time-dependent trends. Subgroup analysis was conducted that stratified results according to cervical fusion, thoracolumbar fusion, and noninstrumented surgery. RESULTS The authors identified 218,648 surgical procedures performed in 10 Medicaid expansion states and 118,693 procedures performed in 4 nonexpansion states. Medicaid expansion was associated with a 17% (95% CI 2%–35%, p = 0.03) increase in mean hospital spine surgical volume and a 23% (95% CI −0.3% to 52%, p = 0.054) increase in Medicaid volume. Privately insured surgical volumes did not change significantly (incidence rate ratio 1.13, 95% CI −5% to 34%, p = 0.18). The increase in Medicaid volume led to a shift in payer mix, with the proportion of Medicaid patients increasing by 6.0 percentage points (95% CI 4.1–7.0, p < 0.001) and the proportion of private payers decreasing by 6.7 percentage points (95% CI 4.5–8.8, p < 0.001). Although the magnitude of effects varied, these trends were similar across procedure subgroups. CONCLUSIONS Medicaid expansion under the Affordable Care Act was associated with an economically and statistically significant increase in spine surgery volume and the proportion of surgical patients with Medicaid insurance, indicating improved access to care.

e18567 Background: The Affordable Care Act (ACA) increased insurance coverage for low-income individuals, which should potentially lead to better access to care and improved oncological outcomes. This study seeks to evaluate the impact of Medicaid expansion (ME) on care for pancreatic ductal adenocarcinoma (PDAC). Methods: Patients who were uninsured or on Medicaid and diagnosed with PDAC between 2004 and 2017 were queried from the National Cancer Database (NCDB). Two different expansion cohorts were included: early expansion states and 2014 expansion states. For early expansion states, the time period of pre-expansion was 2004-2009 and post-expansion was 2010-2017. As for the 2014 expansion states, the pre-expansion period was from 2004-2013 and post-expansion period was from 2014-2017. Patients in non-expansion states formed the control group. A difference-in-difference (DID) analysis was used to assess the association of ME with stage of diagnosis, treatment and survival for each expansion cohort. Results: In both early and January 2014 expansion states, there was an increase in overall Medicaid coverage (Early: DID = 0.29, 2014: DID = 0.37; P < 0.001), in particular for non-Hispanic Black and Hispanic Black patients (Non-Hispanic Black: Early: DID = 0.11, 2014: DID = 0.11; P < 0.001, Hispanic-Black: 2014: DID = 0.20; P = 0.003). There were no differences in early stage diagnosis (Early: DID = 0.02, 2014: DID = -0.02; P > 0.05). There was an increase in the number of patients receiving surgery (Early: DID = 0.05; P = 0.001, 2014: DID = 0.03; P = 0.029) but no difference in time to surgery among patients receiving surgery upfront (Early: DID = 1.75, 2014: DID = 0.38; P > 0.05). There was no difference in 30-day readmission post-surgery (Early: DID = 0.003; 2014: DID = -0.00007; P > 0.05) or 90-day mortality (Early: DID = -0.007, 2014: DID = -0.035; P > 0.05). Moreover, there was no difference in receipt of chemotherapy (Early: DID = 0.01, 2014: DID = 0.005; P > 0.05) or time to chemotherapy for patients receiving neoadjuvant chemotherapy (Early: Early: DID = 9.62, 2014: DID = 0.01; P > 0.05). Finally, there was no difference in receipt of palliative care among stage IV patients in both cohorts (Early: DID = -0.004, 2014: DID = 0.004; P > 0.05). Conclusions: This study suggests that after ME, PDAC patients were more likely to be insured and had increased access to surgical care. Future, studies should evaluate the implications of improved surgical access on clinical outcomes such as mortality.

The Impact

Abstract The U.S. Supreme Court’s decision to grant states the authority to reject Medicaid expansion under the Affordable Care Act without penalty threatened the implementation of this polarized health policy. While many Republican-controlled states followed their national allies and rejected Medicaid expansion, others engaged in bipartisan implementation. Why were some Republican states willing to reject the national partisan agenda and cooperate with Democrats in Washington? I focus on the role of electoral competition within states. I conclude that although electoral competition has been shown to encourage partisan polarization within the states, the combination of intergovernmental implementation and Medicaid expansion’s association with public welfare reverses this dynamic. I employ a Cox proportional-hazards model to examine the impact of state partisan ideology and competition on the likelihood of state Medicaid expansion. I find that strong inter-party competition mitigates the impact of more extreme partisan ideologies, encouraging potentially bipartisan negotiation with the federal administration.
