Investigating the causal effect of socioeconomic status on quality of care under a universal health insurance system - a marginal structural model approach.

ABSTRACT:

Background

Social disparities in healthcare persist in the US despite the expansion of Medicaid under the Affordable Care Act. We investigated the causal impact of socioeconomic status on the quality of care in a setting with minimal confounding bias from race, insurance type, and access to care.
