Rising use of observation care among the commercially insured may lead to total and out-of-pocket cost savings.
Using multipayer commercial claims for the period 2009-13, the investigators evaluated utilization and spending among patients admitted for six conditions that are commonly managed with either observation care or short-stay hospitalizations. In their study period, the use of observation care increased relative to that of short-stay hospitalizations. In addition, total and out-of-pocket spending were substantially lower for observation care, though both grew rapidly--and at rates much higher than spending in the inpatient setting--over the study period.

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.

How do Medicare Advantage beneficiary payments vary with tenure?
This study compared how premiums and expected out-of-pocket medical costs (OOPC) vary with the length of time Medicare Advantage (MA) beneficiaries have been enrolled in their plans. Beneficiaries who remained in their plans for 6 or more years were paying $786 more than they would have spent in the lowest-cost plan compared with $552 for beneficiaries in their first year of enrollment.

Managed care and inpatient mortality in adults: effect of primary payer.
This study provides a comprehensive assessment of the association between managed care and inpatient mortality for Medicare and privately insured patients. Privately insured patients in managed care plans, especially older adults, had better outcomes than those in fee-for-service (FFS) plans. Patients in Medicare managed care had outcomes similar to those in Medicare FFS.

Dropped out or pushed out? Insurance market exit and provider market power in Medicare Advantage.
This paper explored how provider and insurer market power affect which markets an insurer chooses to operate in. The investigators found that overall, insurers in the most concentrated hospital and physician markets were 9 and 13 percentage points more likely to exit, respectively, than those in the least concentrated markets. Conversely, insurers with more market power were less likely to exit than those with less, and an insurer's market power had the largest effect on exit in concentrated hospital markets.
