Medicaid patients twice as likely to visit ER

Medicaid patients tend to be in worse health and visit the emergency room more, often as a result of having barriers—more so than privately insured patients—to seeing their primary care physician, a new report finds.

A study published online this week in Annals of Emergency Medicine found as many people insured by Medicaid as by private insurance report barriers to primary care. But Medicaid patients are twice as likely to visit the emergency department.

"Even those Medicaid patients who have primary care physicians – and that is less likely than for people with private insurance—report significant barriers to seeing their doctor," said senior author Adit Ginde of the University of Colorado School of Medicine in Aurora, Colo. "Medicaid patients tend to visit the ER more, partly because they tend to be in poorer health overall. But they also visit the ER more because they can't see their primary care provider in a timely fashion or at all."

The study authors analyzed 230,238 adult responses to the 1999-2009 National Health Interview Survey for an association between barriers to primary care and use of the emergency department. Overall, 16.3 percent of Medicaid beneficiaries had one or more barriers to primary care, compared to 8.9 percent of people with private insurance. More than a third of Medicaid patients (39.6 percent) visited the ER within the last year versus 17.7 percent of privately insured patients.   

"Our findings are particularly worrisome in light of the additional 16 million people who will be added to the Medicaid rolls over the next decade," Ginde said. "The shortage of primary care providers in the U.S. seems to affect Medicaid patients disproportionately and more harshly." 

Even comparing patients with barriers to primary care side by side, Medicaid beneficiaries were still more likely to visit the emergency department than those with private insurance (61.2 percent vs. 28.9 percent for patients with two or more barriers to primary care). Barriers included not being able to reach a doctor by phone, not being able to get a timely appointment and lack of transportation to the doctor's office.

"The efforts by some states to keep Medicaid patients out of the ER do not take this lack of access to primary care into account," said David Seaberg, president of the American College of Emergency Physicians. "It puts both patients and providers into an impossible position that will only get worse as more people enroll in Medicaid."
