Acute Low Back Pain
Low Back Pain (LBP) is Very Common, Causing More Disability Around the World Than Any Other Condition
In one study, it was the most common type of pain reported by patients, with 25% of U.S. adults reporting LBP in the prior 3 months.
LBP is frequently classified based on several clinical characteristics, including duration of symptoms.
- Acute back pain is often defined as lasting less than 4 weeks.
- Subacute back pain lasts 4 to 12 weeks.
- Chronic back pain lasts more than 12 weeks.
Many patients do not present for medical care for acute LBP, as it typically will resolve on its own without intervention.
Opioids Continue to be Prescribed for LBP, Despite an Overall Lack of Evidence to Support its Efficacy
Despite an overall lack of evidence to support its efficacy, opioids continue to be prescribed to treat acute LBP when patients seek medical evaluation. In one study, 13.7% of 2017 visits for acute LBP covered by private insurance were associated with an opioid prescription. Prescriptions were for a median days’ supply of 7 (interquartile range 4-15 days) and median daily dosage of 21.4 MMEpdf icon. Another recent study found that in 2015, 27% of opioid-naïve patients with newly diagnosed low back or extremity pain received an opioid prescription.
Almost 14% of insured patients who sought care for low back pain, were prescribed opioids.
Too Many Pills, Too Many Times
Opioids are prescribed for acute low back pain at a median total of 21.4 MME and an average of 7 days supply.
Summary of Treatment Recommendations
“Routine opioid use for treatment of nonsevere acute pain (e.g., low back pain, sprains, or minor injury without signs of tissue damage [is not recommended].”
“Given that most patients with acute or subacute low back pain improve over time regardless of treatment, clinicians and patients should select nonpharmacologic treatment with superficial heat (moderate-quality evidence), massage, acupuncture, or spinal manipulation (low-quality evidence). If pharmacologic treatment is desired, clinicians and patients should select nonsteroidal anti-inflammatory drugsexternal icon or skeletal muscle relaxants (moderate-quality evidence).”
“…The use of opioids [in the acute phase] for non-specific low back pain, headaches, and fibromyalgia is not supported by evidence.”
