Reduced use of emergency care and hospitalization in patients with traumatic brain injury receiving acupuncture treatment.

Background. Little research exists on acupuncture treatment's effect on patients with traumatic brain injury (TBI). Methods. Using Taiwan's National Health Insurance Research Database, we conducted a cohort study to compare the use of emergency care and hospitalization in TBI patients with and without acupuncture treatment in the first year after TBI. The adjusted relative risks (RRs) and 95% confidence intervals (CIs) of high use of emergency care and hospitalization associated with acupuncture treatment were calculated in multivariate Poisson regression models with generalized estimating equation. Results. The means of medical visits of emergency care and hospitalization were lower in TBI patients with acupuncture treatment than in those without acupuncture treatment. After adjustment, acupuncture treatment was associated with decreased risk of high emergency care visits (beta = -0.0611, P = 0.0452) and hospitalization (beta = -0.0989, P < 0.0001). The RRs of high medical visits and expenditure for hospitalization associated with acupuncture treatment were 0.62 (95% CI = 0.50-0.76) and 0.66 (95% CI = 0.53-0.83), respectively. Conclusion. Patients with TBI who receive acupuncture treatment have reduced the use of emergency care and hospitalization in the first year after injury. The mechanisms of effects of acupuncture on TBI warrant further investigations.
