New Guidelines for Treating Low Back Pain-American College of Physicians

Approximately one quarter of U.S. adults reported having low back pain lasting at least one day in the past three months.

Low back pain is associated with high costs, including those related to health care and indirect costs from missed work or reduced productivity.

In 2006, the total costs attributable to low back pain in the United States were estimated at $100 billion.

Pain is categorized as:

• acute if its lasts less than four weeks
• subacute if it lasts from four to 12 weeks
• chronic is it lasts more than 12 weeks

"Physicians should reassure their patients that acute and subacute low back pain usually improves over time regardless of treatment," said Nitin S. Damle, MD, MS, MACP, president, ACP.

"Physicians should avoid prescribing unnecessary tests and costly and potentially harmful drugs, especially narcotics, for these patients." Dr. Damle added.

The evidence showed that acetaminophen was not effective at improving pain outcomes versus placebo. Low-quality evidence showed that systemic steroids were not effective in treating acute or subacute low back pain.

ACP recommends that for patients with chronic low back pain, physicians and patients initially consider non-drug therapy with exercise, multidisciplinary rehabilitation, acupuncture, mindfulness-based stress reduction, tai chi, yoga, motor control exercise (MCE), progressive relaxation, electromyography biofeedback, low level laser therapy, operant therapy, cognitive behavioral therapy, or spinal manipulation.

"For the treatment of chronic low back pain, physicians should select therapies that have the fewest harms and costs, since there were no clear comparative advantages for most treatments compared to one another," Dr. Damle said. "Physicians should remind their patients that any of the recommended physical therapies should be administered by providers with appropriate training."

If non-drug therapy does not bring about the desired effect in patients with chronic low back pain, ACP recommends that physicians and patients consider treatment with NSAIDs as first line therapy; or tramadol or duloxetine as second line therapy.

Opioids should be considered as a treatment option if only:

• the aforementioned treatments have failed
• only if the potential benefits outweigh the risks for individual patients
• after a discussion of known risks and realistic benefits with patients

"Physicians should consider opioids as a last option for treatment and only in patients who have failed other therapies, as they are associated with substantial harms, including the risk of addiction or accidental overdose," said Dr. Damle.

Conclusion

The new guidelines are based on a systematic review of randomized controlled trials and systematic reviews published on noninvasive pharmacological and non-pharmacological treatments of nonradicular low back pain.

Clinical outcomes evaluated included:

• reduction or elimination of low back pain
• improvement in back-specific and overall function, health-related quality of life, patient satisfaction
• reduction in work disability/return to work, global improvement, number of back pain episodes or time between episodes and adverse effects

For radicular low back pain, the evidence was insufficient. Radicular low back pain is a result of severe nerve impingement and results in lower extremity pain, paresthesia, and/or weakness. Also the guideline does not address topical therapies or epidural injection therapies.
