Polycystic ovary syndrome (PCOS) is a common endocrine disease of reproductive-age women, accounting for about 9% to 18% of all women in this age group. Hyperandrogenemia, oligomenorrhea, or amenorrhea or anovulation, and polycystic ovary morphology are the 3 main criteria used to diagnose PCOS currently. Substantial scientific evidence and consensus on treating Taiwanese PCOS was lacking. The aim of this study is to investigate the characteristics and utilization of traditional Chinese medicine (TCM) among Taiwanese women with PCOS. The data used in this study were derived from the Longitudinal Health Insurance Database (LHID 2000 and LHID 2005). Demographic characteristics, TCM usage, the frequency, as well as average daily dose of Chinese herbal formulas and the single herbs prescribed for patients with PCOS, were analyzed. Chinese herbal formulas and the single herbs prescribed for PCOS women during 1999 to 2013 were extracted to build up Chinese Herbal Medicine prescription database. In our study, 66.43% (n = 8205) women sought TCM treatment because of PCOS for infertility or menstrual disorders. The most commonly prescribed Chinese herbal formula was Jia-wei-xiao-yao-san (Supplemented Free Wanderer Powder). The most commonly prescribed single herb was Yi-mu-cao ( Leonuri herba ). Among top 20 Chinese herbal formulas, Si-wu-tang has the largest average daily dosage (9.60 g). Our study identified the characteristics and prescription patterns of TCM for patients with PCOS in Taiwan. We may need do further longitudinal research for TCM and its long-term response for improvement of pregnancy rate and reduction of metabolic disease rate.
Background: Uterine myoma is a common gynecological disease in women of reproductive age. Owing to surgery and treatment-related complications, many patients opt for alternative therapy, such as traditional Chinese medicine (TCM). However, there is no standard treatment protocol for TCM. This study aimed to investigate the prescription patterns of TCM for uterine myoma and compare differences between the Chang Gung Research Database (CGRD) and the National Health Insurance Research Database (NHIRD). Methods: Data of 217040 patients newly diagnosed with uterine myoma between 2005 and 2014 were retrieved from the CGRD using the International Classification of Diseases, Ninth Revision, Clinical Modification code for myoma and related symptoms. We analyzed patient demographics, frequencies and average daily doses of prescribed Chinese herbal formulas and single herbs, and iron supplementation doses. Associations between Chinese herbal formulas and single herbs commonly used for uterine myoma were analyzed by association rule mining (ARM) and social network analysis (SNA).Results: In total 45,436 patients used TCM. Most participants (49.1%) were aged 30–44 years. Jia-Wei-Xiao-Yao-San (28.2%; average daily dose 4.85 g) and Xiang-Fu (22.0%; average daily dose 1.10 g) were the most frequently prescribed herbal formula and single herb, respectively. Additionally, the Si-Wu-Tang decoction was often used for uterine fibroids. Common prescription patterns and herbal pairs were identified. Western medicine (WM) outpatient visits (12 ± 19.6) and iron supplement prescriptions (prescription code PLB001M, 62.5 ± 115.3 pills; PLB012M, 24.6 ± 78 pills) were more prevalent in the combined therapy group than in the WM-only group (outpatient visits: 5.9 ± 6.7 times; iron supplements: PLB001M, 48.3 ± 98.4 pills; PLB012M, 20.9 ± 67.5) in the CGRD. Conclusions: We characterized the prescription patterns for uterine myoma in the CGRD. Chinese herbal medicine prescriptions may aim to improve anemia related to hypermenorrhea caused by uterine myoma. Ours is the first study of TCM myoma treatment within the CGRD, and we compared our findings to the TCM NHIRD myoma study results. ARM and SNA of TCM prescription patterns provide an evidence base to inform medical education and medical decision-making.
