The Impact of the Affordable Care Act Insurance Expansions on Opioid-Related Emergency Department Visits.
The authors leveraged ACA coverage expansions, including Medicaid expansion and Marketplaces, to study the impact of health insurance on opioid-related emergency department (ED) visits. They used ZIP-code–level ED utilization data from HCUP’s State Inpatient Databases (SID) and State Emergency Department Databases (SEDD) for 29 states. They found evidence of a dose-response relationship between pre-ACA uninsured and changes in ED visit rates in both expansion and non-expansion states: areas with higher uninsured rates prior to ACA saw larger reductions in opioid-related ED visits after the ACA took effect. The authors concluded that these findings suggest that increased insurance coverage may to help mitigate the opioid crisis.

Shift in U.S. payer responsibility for the acute care of violent injuries after the Affordable Care Act: Implications for prevention.
In this study, the investigators determined the total annual charges for the acute care of injuries from interpersonal violence and the shift in financial responsibility for these charges after the Medicaid expansion from the Affordable Care Act in 2014. After Medicaid expansion, taxpayers are now accountable for nearly half of the $10.7 billion in annual charges for the acute care of violent injury in the U.S. The investigators suggest that these findings highlight the benefit to state Medicaid programs of preventing interpersonal violence.

The Affordable Care Act reduces emergency department use by young adults: evidence from three States.
The authors tested the impact of the Affordable Care Act (ACA) on how young adults used ED services. They found that the largest relative decreases were found in women and blacks. This relative decrease in ED use implies a total reduction of more than 60,000 visits from young adults across three states in 2011.
