PHOENIX - With emergency department visits spiking around the holidays, patients may be inclined to seek care at freestanding emergency departments in an urgent situation.

However, a new study suggests the best and most cost-effective option may be to skip the freestanding emergency department and head to an urgent care center.

A collaborative study led by researchers at the University of Arizona College of Medicine - Phoenix and Rice University found that freestanding emergency departments can increase out-of-pocket spending, health-care utilization and price per visit. Freestanding emergency departments deliver emergency care similar to a hospital ER. However, unlike an ER, these freestanding clinics are not physically attached to an acute-care hospital.

"Recent years have seen a significant increase in emergency department visits, and also a boom in openings of freestanding emergency departments," said Murtaza Akhter, MD, co-author of the study and assistant professor in the Department of Emergency Medicine at the College of Medicine - Phoenix. "Our study showed that an increase in freestanding emergency departments was associated with an increase in spending, per Blue Cross Blue Shield enrollees."

Dr. Akhter collaborated on the study with Vivian Ho, PhD, and Yingying Xu, PhD, both from Rice University. Researchers analyzed Blue Cross Blue Shield insurance claims data from Texas, Arizona, Florida and North Carolina, as well as data from the U.S. Census Bureau American Community Survey. The results were published Oct. 23 in Academic Emergency Medicine.

The researchers found that entry of an additional freestanding emergency department was associated with an increase in emergency department utilization in Texas, Florida and Arizona, but not in North Carolina.

The implied increases in utilization varied between roughly 3 and 5 percent. The estimated out-of-pocket payments for emergency care increased 3.6 percent with the entry of a freestanding emergency department in Texas, Florida and Arizona, but declined 15.3 percent in North Carolina.

Additionally, researchers discovered that freestanding emergency departments in a local market were associated with a 3.6-percent increase in emergency provider reimbursement, per insured beneficiary in all three states, except Arizona. (Health-care reimbursement is the payment that your health-care provider receives for giving a medical service.)

"Opening freestanding emergency departments can have various effects, and that typically leads to increased health-care costs," Dr. Akhter said. "This often is due to increased utilization, thereby making freestanding emergency departments supplements to hospital-based emergency departments, rather than substitutes."
