Key clinical point: Expanded Medicaid coverage under the Affordable Care Act did not lead to decreased odds of preventable hospitalizations for lupus patients.

Major finding: After adjusted analysis, the four states with expanded Medicaid had significantly higher odds of having preventable hospitalizations than did the four that did not expand Medicaid (odds ratio, 1.302; 95% confidence interval, 1.119-1.515).

Study details: A retrospective, quasi‐experimental study using data from eight states, four that expanded Medicaid under the ACA and four that did not.

Disclosures: The study was partially supported by the South Carolina Clinical & Translational Research Institute via a National Center for Advancing Translational Sciences grant. The authors reported no conflicts of interest.
