Unnecessary Back Surgeries Performed Every 8 Minutes at U.S. Hospitals

By Pat Anson

Over 200,000 unnecessary or “low value” back surgeries have been performed on older patients at U.S. hospitals over the last three years, about one procedure every eight minutes, according to a new report.

The analysis by the Lown Institute estimates the potential cost to Medicare at $2 billion for unnecessary spinal fusions, laminectomies and vertebroplasties. The procedures either fuse vertebrae together, remove part of a vertebra (laminectomy), or inject bone-like cement into fractured vertebrae (vertebroplasty) to stabilize them.

Lown maintains that fusions and laminectomies have little or no benefit for low-back pain caused by aging, while patients with spinal fractures caused by osteoporosis receive little benefit from vertebroplasties.

“We trust that our doctors make decisions based on the best available evidence, but that’s not always the case,” said Vikas Saini, MD, president of the Lown Institute, an independent think tank that analyzed Medicare and Medicare Advantage claims from 2019 to 2022.  

“In spinal surgery, as with other fields of medicine, physicians routinely overlook evidence to make exceptions, sometimes at shockingly high rates. This type of waste in Medicare is costly, both in terms of spending, and in risk to patients.”

Up to 30 million Americans receive medical care for spine problems each year. While surgery is appropriate for some, the Lown Institute considers many common surgeries overused and of low value to patients. Potential risks include infection, blood clots, stroke, heart and lung problems, paralysis and even death.

Spinal fusions and laminectomies are considered useful for patients who have low back pain caused by trauma, herniated discs, discitis, spondylosis, myelopathy, radiculopathy and scoliosis. Fusions are also appropriate for patients with spinal stenosis from neural claudication and spondylolisthesis; and laminectomies are appropriate for patients with stenosis who have neural claudication.

Wide Variation in Overuse Rates

Nationwide, about 14% of spinal fusions/laminectomies met the criteria for overuse, while 11% of surgery patients with osteoporosis received an unnecessary vertebroplasty.  

The Lown Institute found a wide variation in overuse rates at some of the nation’s largest and most prestigious hospitals. UC San Diego, for example, had a 1.2% overuse rate for fusions and laminectomies; while the Hospital of the University of Pennsylvania had a 32.6% overuse rate.

The largest overuse rate was at Mt. Nittany Medical Center in Pennsylvania, where nearly two-thirds (62.8%) of the fusions and laminectomies were considered inappropriate or of low value.

The Lown report found that over 3,400 doctors performed a high number of low-value back surgeries. Those physicians received a total of $64 million from device and drug companies for consulting, speaking fees, meals and travel, according to Open Payments. Three companies — Nuvasive, Medtronic and Stryker — paid over $22 million to doctors who performed the unnecessary surgeries.

Previous reports by the Lown Institute have also questioned the value of procedures such as knee arthroscopies, a type of “keyhole” surgery in which a small incision is made in the knee to repair ligaments. Research has found that arthroscopic surgeries provide only temporary relief from knee pain and do not improve function long-term.

The American Hospital Association takes a dim view of Lown studies, calling the data cherry-picked and misleading.

100,000 ‘Unnecessary’ Hospital Procedures Performed in First Year of Pandemic

U.S. hospitals performed over 100,000 “low-value” procedures on Medicare patients in the first year of the Covid pandemic, including tens of thousands of spinal surgeries and knee arthroscopies, according to a recent study by the Lown Institute, a non-profit that seeks to reduce the use of unnecessary and ineffective medical treatments.

In 2020, no vaccines were available, the elderly were particularly vulnerable to the Covid-19 virus, and intensive care units were filled with infected patients. Yet many hospitals continued to perform questionable elective procedures at the same rate they did in 2019.

“You couldn’t go into your local coffee shop, but hospitals brought people in for all kinds of unnecessary procedures,” Vikas Saini, MD, president of the Lown Institute, said in a statement. “The fact that a pandemic barely slowed things down shows just how deeply entrenched overuse is in American healthcare.”

Lown researchers analyzed Medicare claims from U.S. hospitals for eight procedures that the non-profit considers to have “little to no clinical benefit” and are potentially harmful.  

Coronary stents were the most overused procedure, with over 45,000 balloon angioplasties performed to open up blocked arteries. The Lown Institute has long maintained that stents are unnecessary and risky in patients with stable heart disease.

Two spinal surgeries also made the list: 13,541 spinal fusions and 16,553 vertebroplasties were performed on older patients. In vertebroplasty, bone cement is injected into fractured vertebrae to stabilize the spine; while spinal fusions are used to join two or more vertebrae together to prevent them from moving and causing more pain. The Lown Institute considers fusions and vertebroplasties inappropriate for patients with low back pain and osteoporosis.

Nearly 1,600 knee arthroscopies were also performed in 2020, a type of “keyhole” surgery in which a small incision is made in the knee to diagnose and repair ligaments damaged by overuse or osteoarthritis. Recent independent studies have found arthroscopic surgeries provide only temporary relief from knee pain and do not improve function long term.

“There are certain things, certain practices that are just insane. You shouldn’t be doing this. Nobody should pay for this,” said Saini.

Highland Hospital in Rochester, New York was rated as the top hospital in the country for avoiding overuse procedures. Richardson Medical Center in Rayville, Louisiana was ranked as the worst hospital.

The American Hospital Association disputed Lown's ranking system, calling it misleading.

"Throughout the pandemic, but especially in the early months, many nonessential services and procedures were put off due to government restrictions or voluntary actions from hospitals to make room for massive surges of COVID-19 patients," Aaron Wesolowski, AHA's VP of policy research, said in a statement to Becker’s Hospital Review.

"Studies have shown that these delays or sometimes even cancelations in nonemergent care have had some negative outcomes on the health and well-being of patients, who continue to show up at the hospital sicker and with more advanced illnesses. Many of these services may alleviate patients' pain or provide other help to patients. Lown may define these services as 'low value,' but they can be of tremendous value to the patients who receive them."
