The authors concluded that the remaining 55% was largely tied to “fundamental changes,” such as slowed development and adoption of new imaging technology and drugs, increases in out-of-pocket charges for patients, and more efficient practices among health-care providers. “It’s all adding up to a story that says it looks like it’s different from what we’ve seen in the past,” said David M. Cutler, an author and a professor at Harvard.
Of particular importance is the role played by new medical technologies. Historically, most medical tech developments have been innovations in care itself: new drugs, new miracle treatments, new expensive equipment. These have tended to raise health care spending by increasing the amount of care people consume.But now we’re entering an era where medical tech developments are more about data collection and streamlined service delivery. This kind of tech is one of the best hopes we have of bringing health care costs down. These studies are an early sign that this tech may be living up to its promise.The study also makes another important point: increased out-of-pocket spending is driving health care consumption down. When third parties bear the cost of care, patients have little incentive to bring market discipline to the health care sector. When patients have to bear more of the cost themselves, they’re more likely to limit their consumption of care.It’s too early to tell whether the slowdown in health care spending will continue, but the structural changes these studies point to are encouraging. While the political debate over Obamacare continues, the health care industry continues to evolve on its own. So far, we like what we’re seeing.
