Returns to emergency department, observation, or inpatient care within 30 days after hospitalization in 4 states, 2009 and 2010 versus 2013 and 2014.
This study described trends in rates of 30-day, all-cause, unplanned returns to the hospital, including returns for observation stays and ED visits. Increases in observation and ED visits coincided with declines in readmissions for private insurance and Medicare. Return rates rose among patients with Medicaid and the uninsured.

Do people with health insurance coverage who live in areas with high uninsurance rates pay more for emergency department visits?
This study investigated the relationship between the percent uninsured in a county and expenditures associated with the typical emergency department visit. Among those with private insurance, it found that an increase of 1 percentage point in the county uninsurance rate is associated with a $20 increase in the mean emergency department payment. No such association was observed among visits covered by other insurance types.

Changes in emergency department use among young adults after the Patient Protection and Affordable Care Act's dependent coverage provision.
This study examined the effects of the Affordable Care Act’s expansion of family insurance coverage to include dependents up to the age of 26 on the use of the emergency department by 19 to 25 year young adults. It found a modest but statistically significant decrease in ED use related to weekday visits, nonurgent conditions and conditions treatable in other settings.

Impact of subsidized health insurance coverage on emergency department utilization by low-income adults in Massachusetts.
The authors aimed to estimate the change in emergency department (ED) utilization per individual among a cohort who qualified for subsidized health insurance following the Massachusetts health care reform. They concluded that expanding subsidized health insurance did not uniformly change ED utilization for all newly insured low-income adults in Massachusetts.

High utilizers of emergency health services in a population-based cohort of homeless adults.
This study identified predictors of frequent emergency department (ED) use among a population-based sample of homeless adults in Toronto, Ontario. It found that among homeless adults with universal health insurance, a small subgroup accounted for the majority of visits to emergency services. Frequent use was driven by multiple predisposing, enabling, and need factors.

Variation in emergency department admission rates across the United States.
The authors investigated factors related to variation in hospital-level emergency department (ED) admission rates. Using HCUP data, they found that higher proportions of Medicare and uninsured patients, more inpatient beds, lower ED volumes, for-profit ownership, trauma center status, and higher hospital occupancy rates were associated with higher ED admission rates.
