How can the perceptions of Korean medicine doctors aid clinical practice guidelines for patients with degenerative lumbar spinal stenosis?: a cross-sectional survey

Introduction: This study aimed to investigate the perception of Korean medicine (KM) doctors regarding the treatment of degenerative lumbar spinal stenosis (LSS) and explore their opinions on the core clinical questions (CQs) of KM clinical practice guidelines (CPGs) for patients with degenerative LSS. Methods: An online cross-sectional survey distributed via e-mail was conducted in December 2016. The study population included registered KM doctors (KMDs) in South Korea. The e-mail contained 13 questionnaire items regarding the doctors' demographic characteristics and perceptions of the core CQs that should be addressed in CPGs for patients with degenerative LSS. Descriptive analyses were performed to summarize the data. Results: A total of 680 KMDs responded to the survey. Kidney qi deficiency was the most commonly used diagnostic name for degenerative LSS. Acupuncture ranked first in the treatment used for degenerative LSS and in the treatment desired to be included in the development of CPG recommendations. Ojeok-san ((sic), (sic), Wuji-san, Goshaku-san) was the number one herbal medicine, and 5% bee venom pharmacopuncture was the number one pharmacopuncture technique used for degenerative LSS. Drug therapy was the most selected control treatment considered appropriate to assess treatment effectiveness and safety. Pain relief was the most chosen indicator among the indicators considered reasonable to assess therapeutic effectiveness. Conclusion: Results of this study are expected to inform the development of key CQs of the KM standard CPG for degenerative LSS. The involvement of KMDs in the CPG development process can help develop useful and available CPGs.
