Particularly, little is known 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 pre-ACA era, on this disparity measure.Abstract: METHODS: 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 hospitals or low-mortality. Disparity was defined as model-adjusted difference in percentage of patients operated 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, then analyzed using interrupted time series to evaluate the impact of Medicaid expansion.Abstract: RESULTS: Disparity in access to high-volume hospitals by insurance type was reduced by 0.61 percentage points per quarter following expansion (p=0.003). 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 0.86 percentage points per quarter (p<0.001) in access to high-volume hospitals and by 0.48 percentage points per quarter (p=0.005) in access to low-mortality hospitals following Medicaid expansion.Abstract: CONCLUSION: Pre-ACA 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.
