The huge amount of waste in the US health system
Even a divided America can agree on this goal: a health system that is cheaper but doesn’t sacrifice quality. In other words, just get rid of the waste.

A new study, published in JAMA, finds that roughly 20% to 25% of U.S. health care spending is wasteful. It’s a startling number but not a new finding. What is surprising is how little we know about how to prevent it.
William Shrank, a physician who is the chief medical officer of the health insurer Humana and the lead author of the study, said, “One contribution of our study is that we show that we have good evidence on how to eliminate some kinds of waste, but not all of it.”
Following the best available evidence, as reviewed in the study, would eliminate only one-quarter of the waste — reducing health spending by about 5%.
Teresa Rogstad of Humana and Natasha Parekh, a physician with the University of Pittsburgh, were co-authors of the study, which combed through 54 studies and reports published since 2012 that estimated the waste or savings from changes in practice and policy.
Because U.S. health spending is so high — almost 18% of the economy and over $10,000 per person per year — even small percentages in savings translate into huge dollars.
The estimated waste is at least $760 billion per year. That’s comparable to government spending on Medicare and exceeds national military spending, as well as total primary and secondary education spending.
If we followed the evidence available, we would save about $200 billion per year, about what is spent on medical care for veterans, the Department of Education and the Department of Energy, combined. That amount could provide health insurance for at least 20 million Americans, or three-quarters of the currently uninsured population.
The largest source of waste, according to the study, is administrative costs, totaling $266 billion a year. This includes time and resources devoted to billing and reporting to insurers and public programs. Despite this high cost, the authors found no studies that evaluate approaches to reducing it.
“That doesn’t mean we have no ideas about how to reduce administrative costs,” said Don Berwick, a physician and senior fellow at the Institute for Healthcare Improvement and author of an editorial on the JAMA study.
While the lead author works for Humana, he also has experience in government and academia, and this is being seen as a major attempt to refine previous studies of health care waste. Reflecting on the study’s importance, JAMA published several accompanying editorials. A co-author of one editorial, Ashish Jha of the Harvard Global Health Institute and the Harvard T.H. Chan School of Public Health, said: “It’s perfectly possible to reduce administrative waste in a system with private insurance. In fact, Switzerland, the Netherlands and other countries with private payers have much lower administrative costs than we do. We should focus our energies on administrative simplification, not whether it’s in a single-payer system or not.”
After administrative costs, prices are the next largest area that the JAMA study identified as waste. The authors’ estimate for this is $231 billion to $241 billion per year, on prices that are higher than what would be expected in more competitive health care markets or if we imposed price controls common in many other countries. The study points to high brand drug prices as the major contributor. Although not explicitly raised in the study, consolidated hospital markets also contribute to higher prices.
A variety of approaches could push prices downward, but something might be lost in doing so. “High drug prices do motivate investment and innovation,” said Rachel Sachs, an associate professor of law at Washington University in St. Louis.
That doesn’t mean all innovation is good or worth the price. “It means we should be aware of how we reduce prices, taking into consideration which kinds of products and which populations it might affect,” she said.
Likewise, studies show that when hospitals are paid less, quality can degrade, even leading to higher mortality rates.
Other categories of waste examined by the JAMA study encompass inefficient, low-value and uncoordinated care. Together, these total at least $205 billion.
Because health care waste comes from many sources, no single policy will address it. Most important, we have evidence on how to reduce only a small fraction of the waste — we need to do a better job of amassing evidence about what works.
