'Myth' of uninsured overcrowding ERs debunked, study says
October 21, 2008
The uninsured are not responsible for overcrowding in the nation's hospital emergency departments, despite conventional wisdom to the contrary, a study out Tuesday says.
Rather, insured patients represent the majority of the increased use of the nation's emergency departments over the past decade, says the article in the Journal of the American Medical Association.
Even medical researchers get that wrong, say the study's authors, who reviewed work in medical journals and found three common misconceptions about the uninsured and their use of emergency departments.
Those myths are: the uninsured use the emergency department for non-urgent care, they are the leading cause of ER crowding and they use the ER disproportionately to their share of the population.
"I became very frustrated with the number of unsupported assertions in excellent journals," says co-author Manya Newton, an emergency physician at the University of Michigan.
The study found that a higher proportion of patients with public insurance, such as Medicaid and Medicare, use emergency departments than the uninsured.
Yet the uninsured do represent a large percentage of patients in some hospitals where the surrounding city has high levels of uninsured residents, the study says.

The number of visits to emergency rooms nationally rose 19% from 1995 to 2005, even as the number of hospital ERs fell by 9%, the Centers for Disease Control and Prevention reports.
Overcrowding in ERs has many causes. One
problem is that patients can't be moved out of emergency
departments if other parts of the hospital are full or don't
have enough staff, according to
Ann O'Malley, a researcher with the non-partisan think tank Center for Studying Health System Change, says people with insurance often go to the emergency department for problems that could be handled in a doctor's office because they face long waits to see their own doctor — or need help after-hours."We need to strengthen access to care in the community, regardless of what type of insurance people have," O'Malley says. "It's misdirected to make the uninsure
