Study: Injured uninsured more likely to die in ER

CHICAGO - Uninsured patients with traumatic injuries, such as car crashes, falls and gunshot wounds, were almost twice as likely to die in the hospital as similarly injured patients with health insurance, according to a troubling new study.

The findings by Harvard University researchers surprised doctors and health experts who have believed emergency room care was equitable.

"This is another drop in a sea of evidence that the uninsured fare much worse in their health in the United States," said senior author Dr. Atul Gawande, a Harvard surgeon and medical journalist.

The study, appearing in the November issue of Archives of Surgery, comes as Congress is debating the expansion of health insurance coverage to millions more Americans. It could add fodder to that debate.

The researchers couldn't pin down the reasons behind the differences they found. The uninsured might experience more delays being transferred from hospital to hospital. Or they might get different care. Or they could have more trouble communicating with doctors.

The hospitals that treat them also could have fewer resources.

"Those hospitals tend to be financially strapped, not have the same level of staffing, not have the same level of surgeons and testing and equipment," Gawande said. "That also is likely a major contributor."

Gawande favors health care reform and has frequently written about the inequities of the current system.

The researchers took into account the severity of the injuries and the patients' race, gender and age. After those adjustments, they still found the uninsured were 80 percent more likely to die than those with insurance — even low-income patients insured by the government's Medicaid program.

"I'm really surprised," said Dr. Eric Lavonas of the American College of Emergency Physicians and a doctor at Denver Health Medical Center. "It's well known that people without health insurance don't get the same quality of health care in this country, but I would have thought that this group of patients would be the least vulnerable."

Some private hospitals are more likely to transfer an uninsured patient than an insured patient, said Lavonas, who wasn't involved in the new research.

"Sometimes we get patients transferred and we suspect they're being transferred because of payment issues," he said. "The transferring physician says, 'We're not able to handle this.'"

Federal law requires hospital ERs to treat all patients who are medically unstable. But hospitals can transfer patients, or send them away, once they're stabilized. A transfer could worsen a patient's condition by delaying treatment.

The researchers analyzed data on nearly 690,000 U.S. patients from 2002 through 2006. Burn patients were not included, nor were people who were treated and released, or dead on arrival.

In the study, the overall death rate was 4.7 percent, so most emergency room patients survived their injuries. The commercially insured patients had a death rate of 3.3 percent. The uninsured patients' death rate was 5.7 percent. Those rates were before the adjustments for other risk factors.

The findings are based on an analysis of data from the National Trauma Data Bank, which includes more than 900 U.S. hospitals.

"We have to take the findings very seriously," said lead author Dr. Heather Rosen, a surgery resident at Los Angeles County Hospital, who found similar results when she analyzed children's trauma data for an earlier study. "This affects every person, of every age, of every race."
