Is Medicaid expansion associated with increases in palliative treatments for metastatic cancer?

ABSTRACT

Background: Medicaid expansion following the 2010 Affordable Care Act has an unknown impact on palliative treatments. Materials & methods: This registry-based study of individuals with metastatic cancer from 2010 to 2016 identified men and women with metastatic cancer in expansion and non-expansion states who received palliative treatments. A mixed effects logistic regression compared trends in expansion and non-expansion states and generated risk-adjusted probabilities or receiving palliative treatments each year. Results: Despite lower baseline use of palliative treatments, the rate of change was more rapid in expansion states (odds ratio [OR] 1.02; 95% CI 1.01-1.03; p < 0.001). The adjusted probability of receiving palliative treatments rose from 21.3 to 26.0% in non-expansion states, and from 19.7 to 26.9% in expansion states. Conclusion: Use of palliative treatments among metastatic cancer patients increased from 2010 to 2016 with a significantly greater increase in Medicaid expansion states, even when adjusting for demographic differences between states.

Lay abstract Palliative treatments are a crucial tool for improving quality of life among those with advanced and incurable cancer. Increases in palliative treatments have been seen from 2010 to 2016 with a greater rate of increase in states which expanded Medicaid insurance coverage. Increases in insurance coverage in concert with policies to increase coverage of palliative and end of life care may increase access to palliative services.
