Abstract
Background: Medically unexplained symptoms (MUSs) are common in primary care. Atpresent, there are no proven, comprehensive treatments available in primary care forpatients with MUSs. However, MUS has parallels with "subhealth" or Mibyeong from tradi-tional East-Asian medicine, and thus, Mibyeong interventions could be effective in treatingMUS. Unfortunately, studies on Mibyeong and its intervention methods are relatively rare.Methods: We administered a web-based survey to 17,279 Korean medicine (KM) practitionersregistered with the Association of Korean Medicine. The response rate was 4.9% (n = 849).Based on the responses received, we assessed how much they agreed with concepts relatedto Mibyeong on a 7-point scale from "do not agree" to "strongly agree." Respondents werealso asked to indicate how frequently they encountered various subtypes and patterns ofMibyeong, and how frequently they use listed intervention methods.Results: Data from 818 respondents were analyzed after excluding those with no clinicalexperience. On average, respondents were male general practitioners aged between 30 yearsand 49 years, working or living in metropolitan areas such as Seoul, Incheon, and Gyeonggi-do. Responses did not differ by demographics. Respondents generally thought that Mibyeongreferred to subjective or borderline findings without certain disease, and that Mibyeong hasvarious subtypes and patterns. Subtypes included fatigue, pain, and digestion problems; pat-terns were either deficiencies (e.g., qi, blood, and yin deficiency) or stagnations (e.g., liver qidepression and qi stagnation). Decoction was the most frequently used type of interventionfor Mibyeong of all items listed, followed by acupuncture and moxibustion. Patient educa-tion was also recommended, suggesting healthy eating, promoting healthy environment,and exercise.Conclusion: We were able to provide preliminary results on KM practitioners' recognition ofand interventions for Mibyeong, but further research is needed to develop a detailed defi-nition of Mibyeong and its myriad subtypes and patterns, and evaluations of the efficacy ofMibyeong interventions.
