Chinese herbal medicine (CHM) has been commonly used for treating insomnia in Asian countries for centuries. The aim of this study was to conduct a large-scale pharmaco-epidemiologic study and evaluate the frequency and patterns of CHM use in treating insomnia. We obtained the traditional Chinese medicine (TCM) outpatient claims from the National Health Insurance in Taiwan for the year 2002. Patients with insomnia were identified from the diagnostic code of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and an association rule was applied to evaluate the co-prescription of CHM. Results showed that there were 16 134 subjects who visited TCM clinics for insomnia in Taiwan during 2002 and received a total of 29 801 CHM prescriptions. Subjects between 40 and 49 years of age comprised the largest number of those treated (25.3%). In addition, female subjects used CHMs for insomnia more frequently than male subjects (female : male = 1.94 : 1). There was an average of 4.8 items prescribed in the form of either an individual Chinese herb or formula in a single CHM prescription for insomnia. Shou-wu-teng (Polygonum multiflorum) was the most commonly prescribed single Chinese herb, while Suan-zao-ren-tang was the most commonly prescribed Chinese herbal formula. According to the association rule, the most commonly prescribed CHM drug combination was Suan-zao-ren-tang plus Long-dan-xie-gan-tang, while the most commonly prescribed triple drug combination was Suan-zao-ren-tang, Albizia julibrissin, and P. multiflorum. Nevertheless, further clinical trials are needed to evaluate the efficacy and safety of these CHMs for treating insomnia.
BackgroundThe growing popularity of traditional medicine (TM) is reflected in the increasing trend for its use worldwide. Many people are turning to use TM as a complementary or integrative treatment. The aim of this study is to present the first nationwide report describing the use of TM in two countries (South Korea and Taiwan).Materials and methodsTo present the TM utilization patterns between South Korea and Taiwan, we analyzed data from the National Health Insurance cohorts in each country, each of which has approximately one million inhabitants.ResultsIn total, 261,478 (25.5%) of 1,025,340 people in South Korea and 260,529 (26.8%) of 970,866 people in Taiwan used TM services at least once under the National Health Insurance in 2011. Using multivariable logistic regression, TM users in South Korea were significantly more likely to be female, 61–80 years of age and individuals with a high income, and those in Taiwan were significantly more likely to be female, 21–40 years of age and individuals with a middle income. The two countries showed similar utilization patterns in visit seasons. People visited TM clinics more frequently than TM hospitals in both countries. The most common TM treatment in South Korea was acupuncture, whereas in Taiwan, various powdered Chinese herbal preparations were the most commonly used treatment. The most common diseases for people seeking TM services were musculoskeletal system and connective tissue diseases in South Korea and Symptoms, signs, and ill-defined conditions in Taiwan.ConclusionAccording to the National Health Insurance database, about one fourth of the NHI beneficiaries of South Korea and Taiwan had TM use in 2011. Different TM utilization patterns existed between South Korea and Taiwan, which might be due to the differences in insurance coverage between the two countries.
From August 1988 to April 1989, we observed 52 patients who developed so-called 'needle fainting' (or what the Chinese call 'Yun-Cheng' phenomenon) 55 times among a total sample of 28,285 procedures of acupuncture therapy at the Center for Traditional Medicine of Veterans General Hospital in Taipei. Of these syncopal patients, 35 were male and 17 were female. Their mean age was 45 years (with a range of 11 to 72 years). All patients were in an upright position when needle fainting occurred. Their usual manifestations were pallor, cold sweating, nausea, and bradycardia. They all recovered soon after lying down; no one developed a complete loss of consciousness. No mortality was noted. When comparing the patients who experienced syncope during their first visit to our Clinic (Group I, n = 27) with the patients who experienced syncope in a follow-up treatment (Group II, n = 25; 3 patients had 2 episodes in sequential treatments), we found a significantly higher incidence of needle fainting (p less than 0.0001) in Group I patients (27 out of 2,855 or 0.94%) than in Group II patients (28 out of 25,430 or 0.11%). The mean age of Group I patients (39 +/- 15.4 years) was significantly less than that of Group II patients (51.6 +/- 18.0 years) (p less than 0.001). The coexistence of other medical problems was significantly higher in Group II patients (72%) than in Group I patients (18.5%) (p less than 0.0001).
An analysis of the National Health Insurance database of South Korea and Taiwan revealed different utilization patterns of traditional medicine in adult patients with allergic rhinitis between the two countries. We believe these phenomena are due to the difference in the national healthcare systems in both countries.
