What they found was that the Medicaid/Medicare patients could not get a hold of a primary care practitioner when they needed routine human body maintenance. Either they didn't get responses to their attempts to set up appointments, or they faced such a narrow range of treatment options that a visit to the ER was the only logical choice.

The researchers looked at data for two categories of patients: “those who used the emergency department because they felt they needed to get immediate medical care [i.e. true emergencies] and those who used the emergency department because they had trouble accessing care elsewhere.”

Here's what they reported:

“Relative to those with private insurance, adults with Medicaid and Medicare were similarly likely to seek emergency care due to an acuity issue. Adults with Medicaid and those with Medicaid and Medicare (i.e., dual eligible) were more likely than those with private insurance to seek emergency care because of access issues. Reasons for seeking care in an emergency department by health insurance type may be driven more by lack of access to alternate care, rather than by differences in patient-perceived acuity for patients covered by Medicaid insurance.”

Culling the data, the researchers said that Medicaid beneficiaries in particular “often mention the inability to get a hold of their primary care providers, get a return phone call or a same day appointment when needed.”

“There is a misconception that patients with Medicaid insurance are more likely to use emergency rooms for a non-urgent issue when compared with those who have private insurance,” said Dr. Roberta Capp, who led the study. “Medicine is complex and patients, no matter what insurance they have, are not always able to determine what is urgent or not urgent.”

Researchers recommended that health care policymakers “should focus on increasing timely access to primary care, especially for Medicaid beneficiaries. Improved care coordination between patients and emergency providers is also necessary to reduce emergency department utilization. With the implementation of the Affordable Care Act, millions of new patients will be enrolled in Medicaid and added to an already overburdened primary care system.”
