Geographic variation in cesarean delivery in the United States by payer.
This study aimed (1) to determine whether the geographic variation in cesarean delivery rate is consistent for private insurance and Medicaid, and (2) to identify the patient, population, and market factors associated with cesarean rate and determine if these factors vary by payer. It concluded that factors associated with geographic variation in cesarean delivery, a frequent and high-resource inpatient procedure, vary somewhat by payer.

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.

Effect of insurance expansion on utilization of inpatient surgery.
The researchers examined the differential effect of the Massachusetts insurance expansion on the use of discretionary vs. nondiscretionary surgical procedures. They found that discretionary surgery increased 9.3 percent while nondiscretionary surgery decreased by 4.5 percent. The greatest increase in discretionary surgery was observed for nonwhite participants.

Rehospitalization during the first year of life by insurance status.
The authors assessed the association of insurance status on infant rehospitalization in a population-based setting. They found that Medicaid coverage and being uninsured were strong predictors of rehospitalizations, with Medicaid bearing a disproportionate share of the economic burden. Normal birth weight infants had the lowest risk. They further found that jaundice and acute bronchiolitis were the leading causes of rehospitalization within 30 days and 1 year, respectively.
