Back Pain Relief Elusive: More Therapy Is Not Helping

Americans are spending more money trying to ease back and neck pain, but new research suggests those extra dollars are not buying more relief.

"This calls into question whether we're providing treatments to people who are not going to benefit," says study author Brook Martin, a research scientist in the department of orthopedics and sports medicine at the University of Washington.

"This calls for a need for more effectiveness studies and looking at which patients would benefit from treatments and diagnostic tests," he says.

Spine Problems Top List of Concerns

"Spine problems are the most common reason why people of middle age have pain and disability," says Dr. Andrew Sherman of the Spine Institute at the University of Miami. "We need to continue to search for better solutions because, although we have come up with newer techniques of treatments, we still have a large percentage of the population with spine problems who are still disabled."

Sherman adds, "Just because [the study authors] did not find improvement over the entire group doesn't mean that many individuals are not deriving benefit from treatment. There are many individual patients who do see improvements."

According to the article, 26 percent of U.S. adults in 2002 reported lower-back pain, and 14 percent reported neck pain during the previous three months.

Low-back pain alone accounted for about 2 percent of all physician's office visits, exceeded only by routine exams, hypertension and diabetes.

At the same time, there have been increases in the rates of imaging, injections, use of opiates such as morphine and surgery related to spine pain.

But have these expenditures resulted in any actual improvements for patients?

The authors sought to answer this question using data from the Medical Expenditure Panel Survey, which sampled individuals around the nation ages 17 and older from 1997 to 2005.

In 1997, 23,045 individuals were sampled, including 3,139 who reported spine problems. At this time, medical costs for those with spine problems was $4,695, compared with just $2,731 for those without spine problems.

Spending Equals Cost of Major Diseases

In 2005, the survey included 22,258 respondents, including 3,187 with self-reported spine problems. Medical expenditures for those with spine problems was now $6,096, compared with $3,516 for those without back and neck problems.

From 1997 to 2005, expenditures increased 65 percent for patients with spine problems, which was a larger increase than for overall health expenditures during the same time period. There was only a small increase in the estimated number of U.S. adults with spine problems.

The estimated proportion of people with self-reported physical disabilities resulting from spine problems also increased, from 20.7 percent to 24.7 percent.

Most of the cost difference came from outpatient and inpatient services, with a smaller proportion accounted for by prescription medicines. However, the percentage of expenditures related to prescription medications went up more rapidly than expenses for other services.

"That includes a 423 percent increase in expenditures related to narcotic analgesics over that time," says Martin. "There's been a steady stream of new devices and surgical techniques and imaging methods being used over time. There's also been a moderate increase in people with back problems."

The annual expenditures for spine problems are comparable to the amount spent annually on arthritis, diabetes and cancer. All of those figures are dwarfed by the enormous sums spent in this country on heart disease and stroke.
