Medicare's approximately 250 accountable care organizations (ACOs) care for a growing portion of all fee-for-service beneficiaries across the United States. We examined where ACOs have formed and what regional factors are predictive of ACO formation. Understanding these factors could help policy makers foster growth in areas with limited ACO development. ⋯ Key regional factors associated with ACO formation include a greater fraction of hospital risk sharing (capitation), larger integrated hospital systems, and primary care physicians practicing in large groups. Area income, Medicare per capita spending, Medicare Advantage enrollment rates, and physician density were not associated with ACO formation. Together, these results imply that underlying provider integration in a region may help drive the formation of ACOs.

In attempting to explain why hospitals vary in the quality of care delivered to patients, a considerable body of health policy research points to differences in hospital characteristics such as ownership, safety-net status, and geographic location as the most important contributing factors. This article examines the extent to which a patient's type or lack of insurance may also play a role in determining the quality of care received at any given hospital. We compared within-hospital quality, as measured by risk-adjusted mortality rates, for patients according to their insurance status. ⋯ To a lesser extent, privately insured patients also had lower risk-adjusted mortality rates than those in other payer groups. Medicare patients appeared particularly vulnerable to receiving inferior care. These findings suggest that to help reduce care disparities, public payers and hospitals should measure care quality for different insurance groups and monitor differences in treatment practices within hospitals.

Biologics are medicines derived from a biological source. Their high prices and rapid uptake have raised hopes that with the gradual expiration of patents on the first generations of biologics, the advent of lower-cost follow-on products known as biosimilars will help "bend the cost curve." Although biosimilars have been available since 2006 within the European Union and are expected to save $15-$44 billion by 2020, the Food and Drug Administration (FDA) has yet to finalize the necessary regulatory processes for their approval in the United States. The European experience suggests, however, that once these are in place, the US biosimilar market may well emerge as bimodal: Initially, modestly discounted biosimilars deemed noninterchangeable with the original products will compete to become the initial treatment of choice in new patients. Subsequently, a second market may be anticipated for those products able to meet the FDA's higher standard for "interchangeability." In that market, discounts may be more dramatic.

Regionalized trauma care has been widely implemented in the United States, with field triage by emergency medical services (EMS) playing an important role in identifying seriously injured patients for transport to major trauma centers. In this study we estimated hospital-level differences in the adjusted cost of acute care for injured patients transported by 94 EMS agencies to 122 hospitals in 7 regions, overall and by injury severity. ⋯ Of the 248,342 low-risk patients-those who did not meet field triage guidelines for transport to trauma centers-85,155 (34.3 percent) were still transported to major trauma centers, accounting for up to 40 percent of acute injury costs. Adhering to field triage guidelines that minimize the overtriage of low-risk injured patients to major trauma centers could save up to $136.7 million annually in the seven regions we studied.

Considerable attention is being paid to hospital readmission as a marker of poor postdischarge care coordination. However, little is known about another potential marker: emergency department (ED) use. We examined ED visits for Medicare patients within thirty days of discharge for six common inpatient surgeries. ⋯ There was substantial variation-as much as fourfold-in hospital-level ED use for these patients across all six procedures. The variation might signify a failure in upstream coordination of care and therefore might represent a novel hospital quality indicator. In addition, the postdischarge ED visit is an opportunity to ensure that care is properly coordinated and is the last best chance to avoid preventable readmissions.
