Insurers of Last Resort
Demand for uncompensated care is what Garthwaite calls relatively “inelastic”—it remains constant regardless of changes in healthcare supply. To demonstrate this, he and his coauthors Tal Gross of Columbia University and Matthew Notowidigdo of Northwestern University looked at 359 hospital closures from 1987 through 2000. Whenever a hospital closed, the uncompensated care costs for nearby hospitals rose significantly, suggesting that there was a nearly complete spillover effect. “Again, the cost does not go away,” Garthwaite says. “It’s passed on to the remaining hospitals.”
“Previously, it wasn’t clear exactly what kind of role nonprofit hospitals were playing. This demonstrates that they’re serving to fill in the gaps in the social safety net.”
The spillover arises because the Emergency Medical Treatment and Labor Act, passed in 1985, requires that hospitals treat all individuals in need of emergency care regardless of their insurance status.
The government does provide some compensation to hospitals for treating low-income patients. Most of it is in the form of Disproportionate Share Hospital (DSH) payments, which, according to federal law, are owed to any qualified hospital that serves a large number of Medicaid and uninsured patients. But the research shows it is not enough to offset hospital costs. “The DSH payments are less than the uncompensated care that’s provided,” explains Garthwaite.
Nor does the cost fall on those who hold private insurance policies, as many policymakers assume. “There’s this idea that hospitals simply pass on the costs of uncompensated care to privately insured patients by raising prices,” Garthwaite says—a phenomenon known as “cost-shifting,” which some have also interpreted as a “hidden tax” on all Americans.
“We show evidence that it’s not true. If it were true, we wouldn’t see profits fall—but we see profits fall meaningfully following an increase in the share of the population that is uninsured.” Beyond the empirical evidence, though, Garthwaite says it is not clear that hospitals could shift costs in the way many policymakers assume they do. “Hospitals are sophisticated financial organizations,” he says. “If raising prices would have made them more money, they would have already raised prices.”
Ultimately, hospitals are left to absorb at least two-thirds of the cost of all of this uncompensated care, the researchers estimate.
Burden on Nonprofits
Interestingly,
nonprofit hospitals end up absorbing the bulk of this care. A majority of private hospitals in the United States—more than 70 percent—are nonprofit firms and therefore expected to provide a “community benefit” in exchange for tax relief. One key component of this community benefit is charity care for indigent patients. For-profit firms do not face a similar community-benefit standard.
This means that when there are changes in the supply or demand of healthcare services to the poor, most of the burden—in terms of uncompensated care costs—falls on nonprofit hospitals, a finding that sheds new light on the role nonprofits play in the healthcare industry. In contrast to what many believe, nonprofit hospitals are not simply for-profits in disguise. “Previously, it wasn’t clear exactly what kind of role nonprofit hospitals were playing,” he says. “This demonstrates that they’re serving to fill in the gaps in the social safety net.”
The authors note that this burden on hospitals should not be seen as a foregone conclusion that results from health care being a necessary service. “Grocery stores also sell a vital product that is partially financed by the government through food stamps,” Garthwaite says. “But grocery stores that accept food stamps are not required to provide ‘uncompensated food’ for people who aren’t eligible for food stamps or who have already used their monthly benefits.” In both cases—healthcare and food stamps—the government deals with private firms to offer this assistance, but only in the healthcare sector do private firms incur costs beyond what the government compensates for.
