Low back pain (LBP) is a globally prevalent disorder with high social significance. Invasive surgical procedures are increasingly being used to treat LBP despite a lack of solid evidence supporting their long-term benefits. This nationwide retrospective cohort study investigated the association between acupuncture treatment and lumbar surgery rate in patients with LBP.
After matching, 130,089 subjects were included in each study group. The lumbar surgery rate was significantly lower in the acupuncture group than in the control group (hazard ratio [HR] 0.633, 95% confidence interval [CI] 0.576-0.696). A decrease in HR was consistently observed in the acupuncture group for all age strata, except for patients in their 20s (HR 1.031, 95% CI 0.804-1.323). HR for lumbar surgery tended to be further reduced in the older age groups upon acupuncture treatment, with no apparent sex-related differences. Lowered HR in the acupuncture group was continuously observed across all income groups; the higher income group showed a tendency of more significant decrease. Sensitivity analyses showed that the number of acupuncture sessions had no significant impact on the likelihood of lumbar surgery, but also that more intensive acupuncture treatment was associated with further reduction in lumbar surgery rates.
The present results found that administration of acupuncture treatment is associated with lower lumbar surgery rates for LBP patients in Korea.
