Link between healthcare spending, quality unclear

Whether states, hospitals and smaller practices that spend more money on health care provide better treatment is still an open question, according to a new review of past studies. "This is really one of the central issues we're grappling with today in health care," said Peter Hussey from the RAND Corporation in Arlington, Virginia. The topic is especially pressing because although the United States spends more of its budget on health care than any other wealthy nation—and is spending more each year—the World Health Organization ranks its health system 37th.
