Association of race/ethnicity with emergency department destination of emergency medical services transport.
The authors examined the patterns of emergency department (ED) destination of emergency medical services (EMS) transport according to patient race/ethnicity and compared the patterns between those transported by EMS and those who did not draw on EMS. Using Medicare claims data, they found race/ethnicity variation in ED destination for patients using EMS transport, with black and Hispanic patients more likely to be transported to a safety-net hospital ED compared with white patients living in the same zip code.

Complying with the Emergency Medical Treatment and Labor Act (EMTALA): challenges and solutions.
EMTALA, which requires Medicare-participating hospitals to provide emergency care to patients regardless of their ability to pay, plays an important role in protecting the uninsured. Yet many hospitals do not comply. This study examines the reasons for noncompliance and proposes solutions. Respondents identified 5 main causes of noncompliance as well as suggesting methods to improve compliance.

Identification of emergency department visits in Medicare administrative claims: approaches and implications.
The researchers sought to construct an operational definition for ED visitation using a comprehensive Medicare data set and to compare this definition to existing operational definitions used by researchers and policymakers. They concluded that current operational definitions of ED visitation using administrative claims produce different estimates of ED visitation based on the underlying assumptions applied to billing data and data set availability.

Outcomes of basic versus advanced life support for out-of-hospital medical emergencies.
The researchers compared outcomes after advanced life support (ALS) and basic life support (BLS) in out-of-hospital medical emergencies. They found that advanced life support is associated with substantially higher mortality for several acute medical emergencies than BLS.

The transfer instability index: a novel metric of emergency department transfer relationships.
The researchers developed the “transfer instability index” to describe sending hospitals’ relationships with receiving hospitals. They found that emergency departments with a greater share of publicly insured patients had a greater transfer instability index, which may indicate less stable, protocolized, and regionalized transfer relationships.
