Article summary
Plain-language narrative summary
This innovative economic study evaluated the feasibility of collaborative treatment between conventional medicine and acupuncture for chronic low back pain in South Korea, using a Markov decision model to project outcomes over five years. The context is particularly relevant, since in 2010 the South Korean Ministry of Health approved the practice of conventional physicians and Korean medicine doctors working together at the same institution, offering simultaneous collaborative treatment for the same condition. Chronic low back pain affects more than 6.5% of Korean adults and represents a significant public health challenge, with substantial direct and indirect costs. The investigators developed a sophisticated Markov model with four states: acute low back pain, chronic low back pain, well-being, and death.
The simulated population consisted of 10,000 60-year-old women, the group with the highest prevalence of low back pain according to national data. Usual care included nonsteroidal anti-inflammatory drugs, thermotherapy, electrotherapy, and lumbar traction, based on the guidelines of the American College of Physicians and the American Pain Society. Collaborative treatment maintained these interventions and added traditional acupuncture performed by licensed Korean medicine doctors, using points from the bladder, gallbladder, small intestine, kidney, and governing vessel meridians, according to protocols identified in the systematic review. Results of the deterministic analysis showed that usual care resulted in 4.11 quality-adjusted life-years (QALYs) at a cost of 2,988,203 Korean won per person, while collaborative treatment produced 4.24 QALYs at a cost of 3,447,840 won.
The incremental cost-effectiveness ratio was 3,421,394 won per QALY (approximately $2,895.80 USD per QALY), a value significantly below the WHO-recommended threshold of 20,000,000 won per QALY based on per capita GDP. Probabilistic sensitivity analysis revealed that with a threshold of 20,000,000 won per QALY, there is 72.3% probability of collaborative treatment being cost-effective. Value-of-information analysis indicated that future research would be economically justifiable to reduce uncertainties, especially with thresholds between 4,000,000 and 8,000,000 won. The clinical implications are substantial, suggesting that integrating acupuncture into conventional care may represent an economically viable therapeutic strategy for the Korean health system.
The study provides important evidence for national health insurance reimbursement decisions, demonstrating that despite the incremental cost, quality-of-life benefits justify the additional investment. However, several limitations should be considered when interpreting the results, including the need for more robust local data, uncertainties in model parameters, and the 'memoryless' nature of Markov transitions, which may not adequately capture the complexity of chronic low back pain progression.

▸ Clinical Relevance
Chronic low back pain is one of the most prevalent diagnoses in any rehabilitation and pain service, and the decision to incorporate acupuncture into the conventional protocol rarely undergoes a formal economic analysis. This work fills exactly that gap by demonstrating that adding acupuncture to the arsenal of NSAIDs, thermotherapy, electrotherapy, and lumbar traction results in an incremental cost-effectiveness ratio of approximately $2,895 USD per QALY, a figure well below internationally accepted thresholds. For service managers and clinicians who need to justify the inclusion of acupuncture procedures in institutional protocols or negotiate reimbursement with payers, these data provide solid economic substrate. The patient profile studied — 60-year-old women, the highest-prevalence group — is precisely the population that fills physiatry and pain clinics, making the findings directly transferable to everyday practice.
▸ Notable Findings
The 0.13 QALY gain over five years with collaborative treatment may seem numerically modest but translates into sustained improvement in functionality and quality of life in a condition typically refractory to usual care alone. What makes the finding particularly robust is that the probability of cost-effectiveness was 72.3% in probabilistic analysis, representing a relevant safety margin for health policy decisions. The value-of-information analysis also deserves attention: it indicates that thresholds between 4 and 8 million Korean won represent the range where residual uncertainty would still justify investment in further research, suggesting the authors have clarity about where the model is most sensitive to parameter variations — a sign of analytic rigor. The societal perspective adopted, incorporating indirect costs such as productivity loss, strengthens the applicability of the results beyond the strictly clinical scope.
▸ From My Experience
In my musculoskeletal pain practice, the profile described in this work — a patient with chronic low back pain, already using anti-inflammatories and conventional physical therapy without satisfactory remission — is the case we most often refer for acupuncture as adjunctive therapy. I usually see the first functional responses after three to four sessions, with stabilization of the pain picture around the eighth to twelfth session for most patients in this age range. The economic data of the article match what I see empirically: the incremental cost of acupuncture is absorbed by reduced NSAID consumption and the lower need for repetitive diagnostic procedures. I usually combine acupuncture with lumbar stabilization exercise and, when there is evident myofascial component, with dry needling of paravertebral trigger points. Patients with high central sensitization component tend to respond less and require a more structured multimodal approach before starting acupuncture.
