HealthDay News — According to a study recently published in the Journal of the American Medical Association, there was a significant increase in Medicaid revenue for hospitals in states that implemented the Medicaid expansion in 2014.

In an effort to examine the correlation between Medicaid expansion in 2014 and hospital finances, Fredric Blavin, PhD, from the Urban Institute in Washington, DC, conducted an observational study with analysis of data for non-federal general medical or surgical hospitals in fiscal years 2011 to 2014. 

Data included were from a sample including 1200 to 1400 hospitals per fiscal year in 19 states with Medicaid expansion and for 2200 to 2400 hospitals per fiscal year in 25 states without Medicaid expansion.

Blavin found that Medicaid expansion correlated with a decrease of $2.8 million per hospital in mean annual uncompensated care costs (P<.001). Relative to hospitals in states without Medicaid expansion, hospitals in states with Medicaid expansions had an increase of $3.2 million in mean annual Medicaid revenue per hospital (P=.008). 

There was also a significant association for Medicaid expansion with improved excess margins (1.1 percentage points; 95% confidence interval, 0.1 to 2.0; P=.04), but no improvement in operating margins (1.1 percentage points; 95% confidence interval, −0.1 to 2.3 percentage points; P=.06).

“Further study is needed to assess longer-term implications of this policy change on hospitals’ overall finances,” Blavin writes.
