Influence of Medicaid Expansion on Short Interpregnancy Interval Rates in the United States

BackgroundLow-income individuals without health insurance have limited access to health care. Medicaid expansions may reduce kidney failure incidence by improving access to chronic disease care.MethodsUsing a difference-in-differences analysis, we examined the association between Medicaid expansion status under the Affordable Care Act (ACA) and the kidney failure incidence rate among all nonelderly adults, aged 19–64 years, in the United States, from 2012 through 2018. We compared changes in kidney failure incidence in states that implemented Medicaid expansions with concurrent changes in nonexpansion states during pre-expansion, early postexpansion (years 2 and 3 postexpansion), and later postexpansion (years 4 and 5 postexpansion).ResultsThe unadjusted kidney failure incidence rate increased in the early years of the study period in both expansion and nonexpansion states before stabilizing. After adjustment for population sociodemographic characteristics, Medicaid expansion status was associated with 2.20 fewer incident cases of kidney failure per million adults per quarter in the early postexpansion period (95% CI, −3.89 to −0.51) compared with nonexpansion status, a 3.07% relative reduction (95% CI, −5.43% to −0.72%). In the later postexpansion period, Medicaid expansion status was not associated with a statistically significant change in kidney failure incidence (−0.56 cases per million per quarter; 95% CI, −2.71 to 1.58) compared with nonexpansion status and the pre-expansion time period.ConclusionsThe ACA Medicaid expansion was associated with an initial reduction in kidney failure incidence among the entire, nonelderly, adult population in the United States; but the changes did not persist in the later postexpansion period. Further study is needed to determine the long-term association between Medicaid expansion and changes in kidney failure incidence.

1520 Background: The Affordable Care Act (ACA) led to improvements in insurance coverage and care affordability in cancer patients. However, the uninsured rate for the general US reached its nadir in 2016 and has been increasing since. We aimed to quantify the changes in insurance coverage and rate of care unaffordability in cancer survivors from 2016 to 2019. Methods: We queried data from the Behavioral Risk Factor Surveillance System (2016-2019) for cancer survivors ages 18-64 years. Outcomes of interest were the percentage of cancer survivors reporting insurance coverage and the percentage reporting cost-driven lack of care in the previous 12 months. Survey-weighted linear probability models adjusted for covariates (age, sex, race/ethnicity, income, education, marital status, and state Medicaid expansion status) were utilized to estimate the average yearly change (AYC) in the outcomes across 2016-2019. Mediation analyses evaluated the mediating effect of insurance coverage changes on changes in cost-driven lack of care. Results: A total of 178,931 cancer survivors were identified among the survey respondents. The percentage of insured cancer survivors between 2016 and 2019 decreased from 92.4% to 90.4% (AYC: -0.54, 95% CI = -1.03 to -0.06, P =.026). This translates to an estimated 164,638 cancer survivors in the United States who lost insurance coverage in the study period. There were decreases in private insurance coverage (AYC: -1.66, 95% CI = -3.1 to -0.22, P =.024) but increases in Medicaid coverage (AYC: 1.14, 95% CI = 0.03 to 2.25, P =.043). The decreases in any coverage were largest in individuals with income < 138% federal poverty level (FPL) (AYC: -1.14, 95% CI = -2.32 to 0.04, P =.059; compared to > 250% FPL, Pinteraction=.03). Cost-driven lack of care in the preceding 12 months among cancer survivors increased from 17.9% in 2016 to 20% in 2019 (AYC: 0.67, 95% CI = 0.06 to 1.27, P =.03), which translates to an estimated 167,184 survivors in the US who skipped care due to costs. Changes in insurance coverage mediated 27.5% of the observed change in care unaffordability overall (p =.028) and 65.7% in individuals with income < 138% FPL relative to > 250% FPL (p =.045). Conclusions: Between 2016 and 2019, about 165,000 cancer survivors in the United States lost their insurance coverage and a similar number may have skipped needed care due to cost. Loss of insurance coverage was mostly among individuals with low socioeconomic status. Interventions to improve health insurance coverage among cancer survivors, such as the recent executive order to strengthen the ACA and further efforts promoting Medicaid expansion in additional states, may be important factors to mitigate these trends.

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.

Quasi Experimental

7035 Background: Medicaid expansion has been associated with increased access to care and earlier stage at diagnosis among patients with head and neck cancer (HNC). However, it is unclear whether Medicaid expansion has impacted HNC mortality rates. We examined the associations between early Medicaid expansions (2010-2011) with mortality rates for HNC in the United States. Methods: Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) program. SEER*Stat was utilized to obtain mortality rates for early expansion (CA, CT, DC, MN, NJ, and WA) and non-early expansion states (all others) in the year ranges as available in SEER: 2005-2007 (pre-expansion) and 2012-2016 (post-expansion). Deaths in 2008-2011 were excluded as a phase-in/washout period. Difference-in-differences analyses were utilized to compare mortality rates pre- and post-early expansion in early expansion vs. non-early expansion states. The parallel trends assumption was tested comparing changes in HNC mortality rates between early expansion and non-early expansion states from 2002-2004 to 2005-2007 and from 2005-2007 to 2008-2011. Results: There were 6882 and 35459 deaths due to HNC in early expansion and non-early expansion states, respectively. HNC mortality rates (deaths per 100,000) decreased from 2005-2007 to 2012-2016 in both early expansion (2.17 to 1.85, difference = -0.32, 95% CI = -0.42 to -0.22) and non-expansion states (2.59 to 2.43, difference = -0.16, 95% CI = -0.22 to -0.11). Relative to non-expansion states, there was a reduction of 0.16 deaths per 100,000 (95% CI = 0.05 to 0.27, p = 0.007) after early Medicaid expansion in expansion states. However, in parallel trends testing, there was no difference in the change in mortality rates between early expansion and non-expansion states from 2002-2011 (p > 0.37). Conclusions: In this quasi-experimental analysis, there was an association between early Medicaid expansion with decreased HNC mortality. Thus, Medicaid expansion might help decrease disparities associated with access to care among HNC survivors. As longer-term data emerges, additional follow-up will be necessary to understand the mechanisms that underlie the HNC mortality benefits seen in early Medicaid expansion.
