Changes in hospital service demand, cost, and patient illness severity following health reform.
This study examined the effects of expanded Medicaid coverage and the health insurance exchange on the number of hospital inpatient and emergency department (ED) utilization rates, cost, and patient illness severity. There was a significant drop in uninsured inpatient discharges and ED visits in states where Medicaid was expanded. For all by young females, uninsured inpatient discharge rates fell by 39% or greater. In nonexpansion states, the rates remained unchanged or increased slightly. Changes in all-payer and private insurance rates were not as dramatic, as was inpatient costs per discharge and all-payer inpatient costs.

Risk factors for early disenrollment from Colorado's Affordable Care Act marketplace.
This study looked at risk factors for early disenrollment from Colorado’s Affordable Care Act marketplace. Researchers used all-payer claims data from individual market enrollees from 2014-2016. They discovered that nearly 25% Marketplace beneficiaries disenrolled midyear. The hazard rate of disenrollement was 30% lower in individuals with cost-sharing plans and 21% lower for those enrolled in gold plans compared to those enrolled in silver plans without cost-sharing subsidies. There was greater disenrollment in beneficiaries with greater hospital and emergency utilization before disenrollment. Also, young adults were 70% more likely to disenroll than older adults.

Lesbian, gay, and bisexual adults report continued problems affording care despite coverage gains.
This study’s investigators used data from three waves of the Behavioral Risk Factor Surveillance System to examine access to a personal doctor, affordability of care, type of health insurance coverage, and self-reported health in LGB adults in the period January 2014-February 2017 in thirty-one states that implemented the Affordable Care Act system's sexual orientation module.

The long-term uninsured were less likely than the short-term uninsured to gain insurance in 2014.
This study assessed the probability of having insurance in at least 1 month of 2014 for a sample of US citizens aged 19–63 who were uninsured in December 2013. It found that among those uninsured at the end of 2013, 2014 insurance take-up was lower the longer a person had been 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.

Does insurance status influence a patient's hospital charge?
The objective of this study was to determine whether hospitals charge patients differently based on their insurance status. It concluded that conditional on patient characteristics, length of stay, and expected intensity of resource utilization, patients with private insurance and patients with Medicare were charged more (before discounting) than their uninsured counterparts within the same hospital.

California's early ACA expansion increased coverage and reduced out-of-pocket spending for the state's low-income population.
The researchers used data from the National Health Interview Survey to examine the impact of California’s Low Income Health Program. Their study demonstrates that the county-by-county rollout of expanded public insurance coverage in California significantly increased coverage, by 7 percentage points, and significantly reduced the likelihood of any family out-of-pocket medical spending in the previous year, by 10 percentage points, among low-income adults.

Medicaid expansion in opt-out states would produce consumer savings and less financial burden than exchange coverage.
This study simulated potential differences in out-of-pocket spending for uninsured adults gaining eligibility for Marketplace coverage (silver plan) because their states have not used the provisions of the Affordable Care Act to expand Medicaid. Compared with having a Marketplace silver plan, being able to take advantage to expanded Medicaid would reduce average out-of-pocket spending by more than 50 percent for these adults and their families.
