Trends and Patterns in Traditional Chinese Medicine Use Among Chinese Population in Late Adulthood: An Eight-Year Repeated Panel Survey.

Traditional Chinese medicine (TCM), originated from China, is different from Western medicine in theory and practice. This study aimed to document the longitudinal trends and the patterns by demographical characteristics in the prevalence of TCM among the middle-aged and elderly Chinese population. This study used nationally representative longitudinal survey data from the China Health and Retirement Longitudinal Study (CHARLS), covering approximately 20,000 individuals in each panel survey from 2011 to 2018. The questions regarding medication use in the questionnaire was used to identify the TCM users. The prevalence of using TCM for treating chronic diseases among the patients with chronic diseases stabilized between 2011 and 2018, while the prevalence of TCM use for any purpose among the overall population climbed from 19.03% (95% CI 18.37% to 19.69%) in 2011 to 23.91% (95% CI 23.23% to 24.60%) in 2015. Moreover, the prevalence of TCM use for nonchronic conditions among the overall population increased during the same period as well. The TCM users were more likely to be females and city dwellers. The increasing prevalence of TCM use for any purpose among the overall population reflects the increasing influence and potentials of TCM by year. With the expected rising demand in TCM for the following decades in China, more clinical trials on safety and healthcare policy regarding TCM are merited in the future.

Association of Traditional Chinese Medicine Use With Adherence to Prescribed Western Rheumatic Medications Among Chinese American Patients: A Cross-Sectional Survey.

Chinese Americans are a fast-growing immigrant group with worse rheumatic disease outcomes compared to white populations and frequently use traditional Chinese medicine (TCM). Whether TCM use is associated with lower adherence to Western rheumatic medications is unknown. The present study was undertaken to examine adherence to Western medications for systemic rheumatic diseases in the Chinese American immigrant population and its association with TCM use. Chinese Americans actively treated for a systemic rheumatic disease were recruited from 2 Chinatown clinics. Sociodemographic, TCM use, and clinical data were gathered. Self-reported health status was assessed using Patient-Reported Outcome Measurement Information System short forms. Adherence was stratified using the 8-item Morisky Medication Adherence Scale. Factors independently associated with high adherence were identified using multivariable logistic regression. Of 230 subjects, the median age was 55 years (range 20-97 years), 65% were female, 71% had a high school education or less, 70% were enrolled in Medicaid, and 22% reported fluency in English. The most common rheumatic diagnoses were rheumatoid arthritis (41%), systemic lupus erythematosus (17%), and seronegative spondyloarthropathies (15%). One-half reported TCM use in the past year, and 28% reported high adherence to Western rheumatic medications. In multivariable analysis, high adherence was associated with TCM use (odds ratio [OR] 3.96, P < 0.001), being married (OR 3.69, P = 0.004), medication regimen complexity (OR 1.13, P = 0.004), and older age (OR 1.06, P < 0.001), and was negatively associated with anxiety (OR 0.94, P = 0.001). While adherence to Western rheumatic medications was low in this cohort, interestingly, it was higher among TCM users compared to nonusers. TCM use appears to represent a complementary rather than an alternate approach to disease management for these patients. Future studies should evaluate whether TCM use is associated with better disease outcomes.

Traditional Chinese medicine use may reduce medical utility in patients with asthma: a nationwide population-based retrospective cohort study.

Many patients with atopic diseases, including asthma, have sought complementary and alternative medicine and traditional Chinese medicine (TCM) treatments. But, limited clinical studies have yet examined TCM effects on medical utility in asthma patients. To assess the medical utility of TCM in patients with asthma. Population-based retrospective cohort study. We performed a 13-year population-based retrospective cohort study. A total of 5235 asthma patients who were TCM users and 5235 propensity-score matched asthma patients who never used TCM were sampled from the Taiwan National Health Insurance Research Database from 2000 to 2012. We compared these two groups of patients to calculate their medical utility, including numbers of emergency visits and hospitalizations until 2013. Univariate analyses were performed using Chi-square tests for dichotomous variables and t-tests for continuous variables. Cox proportional hazard models were conducted to investigate the medical utility of asthma after TCM use. Compared with non-TCM patients, TCM patients had a significantly decreased medical utility of asthma admission [adjusted odds ratio (OR) = 0.63; 95% confidence interval (CI): 0.46-0.85; P < 0.05], especially in patients who used TCM for >60 days. Asthma medical utility in asthma emergencies was significantly higher for male than for female patients (adjusted OR = 1.45; 95% CI: 1.08-1.96). The most frequently used TCMs for asthma control or cough treatment were antitussive agents. This population-based retrospective cohort study showed a significantly decreased medical utility of emergency visits and admissions in TCM patients, especially using TCM for >60 days.

Predictors for the use of traditional Chinese medicine among inpatients with first-time stroke: a population-based study

BackgroundStroke is one of the major causes of death and disability. The treatments that are provided to patients during hospitalization after an acute stroke are very important in stabilizing their medical condition and enabling the recovery of their motor functions. However, limited information is available regarding the use of traditional Chinese medicine (TCM) during hospitalization for first-time stroke patients. The researchers aimed to investigate the factors affecting TCM use and to provide clinicians with comprehensive information on TCM use among first-time stroke inpatients in Taiwan.MethodsThe researchers collected and analyzed data, including patient characteristics, TCM use, and TCM prescription patterns, from the National Health Insurance Research Database in Taiwan for first-time stroke inpatients between 2006 and 2012.ResultsAmong the 89,162 first-time stroke patients, 7455 were TCM users, and 81,707 were TCM nonusers. The predictors for TCM use were as follows: age, 45–64 or < 45 years; men; living in a level 2, 4, or 7 urbanized area; insured amount ≥ 576 USD per month; ischemic stroke; hospitalized for first-time stroke for 8–14 days, 15–28 days, or ≥ 29 days; stroke severity index score 0–9 or 10–19; Charlson–Deyo comorbidity index score 0 or 1–2; hospitalization in a regional or community hospital; receiving rehabilitation; and previous experience with outpatient TCM use. An increase in the number of TCM users was observed from 2006 to 2012. Furthermore, 68.8–79.7% of TCM users used acupuncture only, while 17.8–26.1% used both acupuncture and Chinese herbal medicine.ConclusionsAn increasing number of first-time stroke patients have been choosing TCM as a complementary treatment during hospitalization. Moreover, TCM use is associated with demographic, clinical, and socioeconomic characteristics. These findings may help clinicians comprehensively understand the trend and the important factors affecting TCM utilization among patients who are hospitalized due to first-time stroke.

Evaluation of the efficacy of Chinese herbal medicine and acupuncture for the prevention of mental disorders in interstitial cystitis patients: A nationwide population-based study.

Traditional Chinese medicine (TCM) is commonly used for urinary symptoms in Eastern countries. Since there are few effective treatments available for patients with interstitial cystitis/bladder pain syndrome (IC/BPS), the psychological burden leads to increased healthcare-seeking behavior. Some patients may therefore seek TCM treatment for related urinary symptoms. Due to limited clinical research evaluating the effects of TCM on IC/BPS, we conducted a nationwide population-based cohort study to investigate the relationship between TCM and mental disorders among these patients. The IC/BPS cohort and its matched non-IC/BPS comparison cohort were recruited from the National Health Insurance (NHI) Research Database between 2000 and 2011. Patients with the use of Chinese herbal medicine (CHM) granules or acupuncture over 90 days per year were enrolled as the TCM users. Multivariable Cox proportional hazards models were used to evaluate the hazard ratio (HR) of mental disorders related to interstitial cystitis. The incidence of mental disorders in the 2 cohorts was assessed with Kaplan–Meier curves. A total of 1123 patients with IC/BPS and 4492 matched non-IC/BPS subjects were included in this study. The IC/BPS cohort demonstrated higher incidence rate of mental disorders than the cohort without IC/BPS (adjusted HR: 2.21, 95% confidence interval [CI]: 1.73–2.81). There was no statistically significant difference in the risk of mental disorders between IC/BPS patients with and without CHM granules or acupuncture treatment (adjusted HR: 0.99, 95% CI: 0.58–1.68). Our results indicated that CHM and acupuncture showed insignificant efficacy in the prevention of mental disorders in IC/BPS patients.

Favorable outcome of adjunctive traditional Chinese medicine therapy in liver cirrhosis: A large cohort study in Southwest China

ObjectiveTo assess the effects of traditional Chinese medicine (TCM) on the survival of patients with liver cirrhosis (LC) in Southwest China. DesignSingle-center, ambispective cohort study conducted from 2012 to 2019. SettingTraditional Chinese Medicine Hospital of Dianjiang Chongqing, Southwest China. Main outcome measureThe primary outcome was the effect of TCM on the survival of patients with LC, as assessed with survival analysis and Cox regression model. ResultsAmong the 691 patients with LC, 364 (52.68 %) received TCM treatment. The mean (standard deviation) follow-up period was 3.53 (1.62) years for non-TCM users and 4.17 (1.53) years for TCM users (P = 0.184). Multivariate analysis revealed that the use of TCM was associated with a significantly decreased risk of mortality (adjusted hazard ratio [HR] = 0.41, 95 % confidence interval [CI] = 0.30 – 0.54) compared with no TCM use. Similarly, the cumulative mortality rates were significantly lower among TCM users, across various subgroups of LC aetiologies. Among the commonly used TCM prescriptions, Xiao Chaihu Tang (XCHT, adjusted HR = 0.17, 95 % CI = 0.07 – 0.42), Yinchen Wuling San (adjusted HR = 0.31, 95 % CI = 0.14 – 0.66), Biejia Ruan Gan Jian (adjusted HR = 0.31, 95 % CI = 0.13 – 0.75), and Chaihu Shu Gan San (adjusted HR = 0.33, 95 % CI = 0.19 – 0.57) were the most effective in improving survival. ConclusionsOur results provide evidence for supporting that adjunctive TCM therapy may potentially improve the survival of patients with liver cirrhosis, and XCHT was the most effective TCM prescription in this study.

Long-Term Traditional Chinese Medicine Combined with NA Antiviral Therapy on Cirrhosis Incidence in Chronic Hepatitis B Patients in the Real-World Setting: A Retrospective Study.

Objective To evaluate the impact of long-term Traditional Chinese Medicine (TCM) syndrome differentiation combined with antiviral therapy with Nucleos (t) ide analogues (NAs) on the incidence of cirrhosis in patients with chronic hepatitis B. Methods This retrospective cohort study included 521 patients with chronic hepatitis B who underwent a treatment course of ≥3 years from 1998–2019. Of the 521 patients, 261 were defined as TCM users while 260 were TCM nonusers (control group). All the enrolled subjects were followed up until February 2019 to measure the incidence and hazard ratio (HR) of cirrhosis, and the Cox proportional hazards regression model was used to analyze the independent factors affecting the occurrence of cirrhosis. Results The cumulative incidence of TCM users and nonusers was 6.9% and 13.5%, respectively (P=0.013). Results of the Kaplan–Meier analysis demonstrated that TCM users had a significantly lower cumulative incidence of cirrhosis than TCM nonusers (P=0.011), and TCM users had a significantly lower liver cirrhosis risk than TCM nonusers (adjusted HR = 0.416, 95% CI, 0.231–0.749). The histological evaluation revealed improved fibrosis in 45.0% of TCM users and 11.1% of TCM nonusers (P=0.033). The analysation of the prescriptions including total 119 single Chinese herbs medicinal demonstrated that “replenish qi and fortify the spleen,” “clear heat and dispel dampness,” and “soothe the liver and regulate qi” are the main treatment methods of TCM for CHB. Conclusions Our study demonstrated that long-term TCM use may attenuate liver cirrhosis risk in patients with chronic hepatitis B (CHB).

Use of Traditional Chinese Medicine for Patients Diagnosed with Postpartum Depression: A Nationwide Population-Based Study.

Postpartum depression (PPD) is one of most common postnatal complications, affecting approximately 10%–15% of women after childbirth annually. Traditional Chinese medicine (TCM) has been gaining popularity as the choice of treatment for PPD in Taiwan. Hence, our aim was to analyze the utilization of TCM among PPD patients in Taiwan. A cross-sectional study was conducted using a random sample of one million beneficiaries selected from the Taiwanese National Health Insurance Research Database. We identified patients with PPD who had received either TCM treatment or non-TCM treatment from the database during 2000–2012. Multivariate logistic regression analysis was used to identify the factors associated with the use of TCM. A total of 653 patients with PPD were enrolled. The majority of patients with PPD were 26–30 years old, lived in a highly urbanized area of Taipei, had a monthly income <20,000 NT$, and were private enterprise employees. Around 52.7% of PPD patients had the motivation to seek TCM services. Younger women, who resided in central and southern Taiwan and who had used TCM one year before PPD diagnosis, were more likely to use TCM services. PPD patients who underwent TCM treatment had a lower overall medical expenditure than non-TCM users. Most TCM users chose simple Chinese herbal medicine. The coexisting factors that made PPD patients to seek TCM services were respiratory or oral infections. We demonstrated the characteristics of those that seek TCM for PPD, which may provide useful insights to health care providers towards resource allocation.

Characteristics of Traditional Chinese Medicine Use for Carpal Tunnel Syndrome.

Carpal tunnel syndrome (CTS) is a common musculoskeletal disorder and an occupational disease caused by repeated exercise or overuse of the hand. We investigated the characteristics of traditional Chinese medicine (TCM) use by practitioners in CTS patients, including demographic variables, socioeconomic status, previous medical conditions, health care use, and hospital characteristics for TCM health care. This cross-sectional study identified 25,965 patients newly diagnosed with CTS based on the first medical diagnosis recorded between 1999 and 2013 in the nationwide representative insurance database of Taiwan. The date of initial CTS diagnosis in outpatient data was defined as the index date, and four patients were excluded because of missing gender-related information. Patients who used TCM care as the first option at their diagnosis were classified as TCM users (n = 677; 2.61%), and all others were TCM non-users (n = 25,288; 97.4%). In the all variables-adjusted model, female patients had an adjusted odds ratio (OR; 95% CI) of TCM use of 1.35 (1.11–1.66). National Health Insurance (NHI) registration was associated with higher odds ratios of TCM use in central, southern, and eastern Taiwan than in northern Taiwan (ORs = 1.43, 1.86, and 1.82, respectively). NHI registration was associated with higher odds ratios of TCM use in rural cities than in urban cities (OR (95% CI) = 1.33 (1.02–1.72)). The TCM group had a 20% less likelihood of exhibiting symptoms, signs, and ill-defined conditions and injury and poisoning. The TCM group had a 56% lower likelihood of having diseases of the musculoskeletal system and connective tissue. Multi-level model outcomes were similar to the results of the all variables-adjusted model, except for the NHI registration outcome in rural and urban cities (OR [95% CI] = 1.33 [0.98–1.81]). Significant associations between the number of TCM visits and TCM use were observed in all logistic regression models. The study presented key demographic characteristics, health care use, and medical conditions associated with TCM use for CTS. Previous experience of TCM use may affect the use of TCM for CTS treatment. This information provides a reference for the allocations of relevant medical resources and health care providers.

Chinese Herbal Medicine and Acupuncture Reduced the Risk of Stroke After Bell's Palsy: A Population-Based Retrospective Cohort Study.

Objectives: Patients with Bell's palsy are more likely to develop stroke than the general population. The therapeutic effect of Traditional Chinese Medicine (TCM) on the risk of stroke in patients with Bell's palsy is unknown. We investigated the risk of stroke according to TCM use in Bell's palsy patients. Design: Records obtained from Taiwan's National Health Insurance Research Database identified 9,863 patients with Bell's palsy, 238 of whom met study inclusion criteria and were categorized as TCM users (n = 119) or non-TCM users (n = 119). TCM treatment modalities and Chinese herbal medicine prescription patterns were analyzed. Cox proportional hazards regression analysis determined the risk of stroke. Results: TCM users were at lower risk of stroke compared with non-TCM users (adjusted hazard ratio [aHR] 0.19; 95% confidence interval [CI], 0.06-0.59; p < 0.004). In subgroup analyses, patients treated with both TCM and oral steroids were at significantly lower risk of stroke compared with those who used neither (aHR 0.05; 95% CI, 0.01-0.22; p < 0.001). The risk of stroke was also lower among those treated with TCM only (aHR 0.25; 95% CI, 0.11-0.59; p < 0.001) or oral steroids only (aHR 0.12; 95% CI, 0.03-0.39; p < 0.01), compared with patients using neither. Conclusion: TCM therapy may lower the risk of stroke after Bell's palsy. However, the retrospective nature of this study and characteristics of the database limit these observational findings. Our results deserve further verification in large-scale prospective studies.

Utilization trends in traditional Chinese medicine for acute myocardial infarction

Ethnopharmacological relevanceAmong heart diseases, acute myocardial infarction (AMI) is the most serious and life-threatening emergency. In Taiwan, heart disease has consistently ranked second among the top 10 leading causes of death since 2007, second only to malignant tumors; however, population-based studies on the use of traditional Chinese medicine (TCM) in AMI cases are limited.Aim of the study: This study investigated the characteristics of TCM users and prescriptions of TCM, and their differences between two cohorts of patients with AMI, identified 10 years apart. Materials and methodsA cross-sectional study was conducted using the Taiwan National Health Insurance claims database. From among two random sample of 1 million beneficiaries selected from the claims database, we identified two cohorts of patients with first hospitalization for AMI in between 2000–2001 and 2010–2011. Patients who had received TCM therapy within one year after hospital discharge were defined as TCM users, whereas, all the other patients with AMI were considered non-users of TCM. We compared the characteristics of TCM use and the patterns of prescriptions between the two cohorts. ResultsThe proportion of patients receiving TCM care was similar between the two AMI cohorts; 20% (85/418) of the patients were diagnosed in 2000–2001 and 21% (169/817) in 2010–2011. In the 2010–2011 AMI cohort, the proportion of men was smaller among TCM users than non-users, and TCM users were less likely to have hyperlipidemia. Among TCM users, the most frequently prescribed herb was Dan-shen (Salvia miltiorrhiza Bunge, Salvia root) in both cohorts. The most commonly used Chinese herbal formulations were Xue-Fu-Zhu-Yu-Tang (Blood Mansion Dispel Stasis) for the 2000–2001 cohort and Zhi-Gan-Cao-Tang (Honey-Fried Licorice Decoction) for the 2010–2011 cohort. ConclusionsThis study revealed the differences in the prescription frequency of Chinese herbal formulation among the two cohort of patients with AMI, suggesting that the practice of prescribing TCM has evolved from post-antique formula to classical remedies during the 10 years evaluated. Further investigations are needed to evaluate if the change in the utilization of Chinese herbal formulations impacts the effectiveness of the treatment.

Effects of adjuvant traditional Chinese medicine therapy on long-term survival in patients with hepatocellular carcinoma

BackgroundMany patients with hepatocellular carcinoma (HCC) in Asian countries seek adjuvant therapy with traditional Chinese medicine (TCM). This study aims to explore the benefits of TCM therapy in the long-term survival of patients with hepatocellular carcinoma in China. Patients and methodsIn total, 3483 patients with HCC admitted to the Beijing Ditan Hospital of Capital Medical University were enrolled in this study. We used 1:1 frequency matching by sex, age, diagnosis time, Barcelona Clinic Liver Cancer staging, and type of treatments to compare the TCM users (n = 526) and non-TCM users (n = 526). A Cox multivariate regression model was employed to evaluate the effects of TCM therapy on the HR value and Kaplan-Meier survival curve for mortality risk in HCC patients. A log-rank test was performed to analyze the effect of TCM therapy on the survival time of HCC patients. ResultsThe Cox multivariate analysis indicated that TCM therapy was an independent protective factor for 5-year survival in patients with HCC (adjusted HR = 0.46, 95% CI 0.40–0.52, p < 0.0001). The Kaplan-Meier curve also showed that after PS matching, TCM users had a higher overall survival rate and a higher progression-free survival rate than non-TCM users. TCM users, regardless of the classification of etiology, tumor stage, liver function level, or type of treatment, all benefited significantly from TCM therapy. In addition, it was found that the most commonly used Chinese patent medications are Fufang Banmao Capsule, Huaier Granule, and Jinlong Capsule. ConclusionUsing traditional Chinese medications as adjuvant therapy can probably prolong median survival time and improve the overall survival among patients with HCC. Further scientific studies and clinical trials are needed to examine the efficiency and safety.

Is Traditional Chinese Medicine Use Associated with Worse Patient-reported Outcomes among Chinese American Rheumatology Patients?

Chinese Americans are a fast-growing immigrant group with more severe rheumatic disease manifestations than whites and often a strong cultural preference for traditional Chinese medicine (TCM). We aimed to examine TCM use patterns and association with patient-reported outcomes (PRO) among Chinese American rheumatology patients. Chinese Americans actively treated for systemic rheumatic diseases were recruited from urban Chinatown rheumatology clinics. Data on sociodemographics, acculturation, clinical factors, and TCM use (11 modalities) were gathered. Self-reported health status was assessed using Patient Reported Outcomes Measurement Information System (PROMIS) short forms. TCM users and nonusers were compared. Factors independently associated with TCM use were identified using multivariable logistic regression. Among 230 participants, median age was 57 years (range 20-97), 65% were women, 71% had ≤ high school education, 70% were on Medicaid insurance, 47% lived in the United States for ≥ 20 years, and 22% spoke English fluently. Half used TCM in the past year; these participants had worse self-reported anxiety, depression, fatigue, and ability to participate in social roles and activities compared with nonusers. In multivariable analysis, TCM use was associated with belief in TCM, female sex, ≥ 20 years of US residency, reporting Western medicine as ineffective, and shorter rheumatic disease duration. Among these Chinese American rheumatology patients, TCM users had worse PRO in many physical and mental health domains. TCM use may be a proxy for unmet therapeutic needs. Asking about TCM use could help providers identify patients with suboptimal health-related quality of life who may benefit from targeted interventions.

Traditional Chinese medicine use is associated with lower end-stage renal disease and mortality rates among patients with diabetic nephropathy: a population-based cohort study

BackgroundDiabetic nephropathy (DN) is a common complication of diabetes mellitus (DM) that imposes an enormous burden on the healthcare system. Although some studies show that traditional Chinese medicine (TCM) treatments confer a protective effect on DN, the long-term impact remains unclear. This study aims to examine end-stage renal disease (ESRD) and mortality rates among TCM users with DN.MethodsA total of 125,490 patients with incident DN patients from 2004 to 2006 were identified from the National Health Insurance Research Database in Taiwan and followed until 2012. The landmark method was applied to avoid immortal time bias, and propensity score matching was used to select 1:1 baseline characteristics-matched cohort. The Kaplan–Meier method and competing-risk analysis were used to assess mortality and ESRD rates separately.ResultsAmong all eligible subjects, about 60% of patients were classified as TCM users (65,812 TCM users and 41,482 nonusers). After 1:1 matching, the outcomes of 68,882 patients were analyzed. For the ESRD rate, the 8-year cumulative incidence was 14.5% for TCM users [95% confidence interval (CI): 13.9–15.0] and 16.6% for nonusers (95% CI: 16.0–17.2). For the mortality rate, the 8-year cumulative incidence was 33.8% for TCM users (95% CI: 33.1–34.6) and 49.2% for nonusers (95% CI: 48.5–49.9). After adjusting for confounding covariates, the cause-specific hazard ratio of ESRD was 0.81 (95% CI: 0.78–0.84), and the hazard ratio of mortality for TCM users was 0.48 (95% CI: 0.47–0.50). The cumulative incidence of mortality increased rapidly among TCM users with ESRD (56.8, 95% CI: 54.6–59.1) when compared with TCM users without ESRD (30.1, 95% CI: 29.4–30.9). In addition, TCM users who used TCM longer or initiated TCM treatments after being diagnosed with DN were associated with a lower risk of mortality. These results were consistent across sensitivity tests with different definitions of TCM users and inverse probability weighting of subjects.ConclusionsThe lower ESRD and mortality rates among patients with incident DN correlates with the use of TCM treatments. Further studies about specific TCM modalities or medications for DN are still needed.

Association of Traditional Chinese Medicine Therapy with Risk of Total Hip Replacement in Patients with Nontraumatic Osteonecrosis of the Femoral Head: A Population-Based Cohort Study.

Background Osteonecrosis of the femoral head (ONFH) contributes to 45% of total hip replacements (THRs) annually in Taiwan. Nontraumatic ONFH (NONFH) is multifactorial; no effective Western medicine is available to delay the disease process. This population-based cohort study investigated the association of traditional Chinese medicine (TCM) therapy with risk of THR in patients with NONFH. Methods This retrospective study was conducted using claims data from all insured residents covered by the National Health Insurance from 2000 to 2010. We enrolled 1,680 newly diagnosed ONFH patients who had not undergone THR, before or within 6 months after diagnosis of ONFH; these patients did not exhibit hip fracture or dislocation before the endpoint. In total, 595 propensity score-matched pairs were selected from among 1,028 TCM users and 652 non-TCM users. The association between TCM use and risk of THR was analyzed using a Cox proportional hazard model. Kaplan-Meier and log rank tests were performed to plot the cumulative incidence of THR. Results The mean follow-up periods were 5.00 years and 3.57 years for TCM and non-TCM cohorts, respectively. Compared to the non-TCM cohort, the TCM cohort had fewer patients undergoing THR surgery (25.4% vs. 18.2%, adjusted hazard ratio: 0.60, p<0.0001). The risk of reduction was noted in the group aged 30–59 years (adjusted hazard ratio: 0.56, p<0.0001), but there was no association with gender nor socioeconomic status. There was a significantly lower cumulative incidence of THR in TCM users (p<0.0001). Shu-Jing-Huo-Xue-Tang and Yan Hu Suo were the most frequently prescribed formula and single herb, respectively. Conclusions NONFH patients using TCM had a lower risk of THR; the risk of reduction was noted in the group aged 30–59 years but was not associated with gender nor socioeconomic status. TCM might be useful in conservative treatment for NONFH.

Integrating traditional Chinese medicine healthcare into dementia care plan by reducing the need for special nursing care and medical expenses.

Reducing the need for advanced nursing care and medical expenses is an essential concern of dementia care. We investigated the impact of traditional Chinese medicine (TCM) on advanced nursing care and medical costs.We used Longitudinal Health Insurance Database to implement a cohort study of patients with dementia between 1997 and 2012 in Taiwan. Data from the onset of dementia to 1st advanced nursing care for the endotracheal tube, urinal indwelling catheterization, and nasogastric tube were assessed using Cox regression proportional hazards model, and independent t test was used to determine the difference of hospitalization costs and days. We also used ANOVA test to compare the hospital cost, hospital stay, and numbers according to different duration of TCM.We assessed 9438 new diagnosed patients with dementia without advanced nursing care were categorized into 2 groups: 4094 (43.4%) TCM users, and 5344 (56.6%) non-TCM users. In the TCM groups, 894 (21.8%) patients were declared as advanced nursing care, while 1683 (31.5%) patients were in non-TCM group. Cox proportional hazard regression indicated that using TCM may decrease the need for advanced nursing care (adjusted hazard ratio (aHR) = 0.61, 95% confidence interval [95% CI]: 0.56–0.66) compared to non-TCM. The TCM users have lower hospitalization costs and hospitalization time compared to non-TCM users.Integrating TCM healthcare into dementia care was found to be associated with a lower need for advanced nursing care, hospitalization costs, and admission time with more benefits from longer durations of TCM use.

Adjunctive Traditional Chinese Medicine Improves Survival in Patients With Advanced Lung Adenocarcinoma Treated With First-Line Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitors (TKIs): A Nationwide, Population-Based Cohort Study.

Objectives: The clinical effect of traditional Chinese medicine (TCM) on survival in patients with advanced lung adenocarcinoma treated with first-line epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) is a major concern and requires more evidence from large-scale clinical studies. Materials and Methods: This population-based cohort study used the Taiwan National Health Insurance Research Database to enroll patients between 2006 and 2012 who had newly diagnosed locally advanced and metastatic lung adenocarcinoma treated with first-line gefitinib or erlotinib. Survival was tracked until 2013. The patients were separated into TCM users and nonusers, and Cox regression models were applied to determine the association between the use of TCM and the survival of patients. Results: A total of 1988 patients receiving first-line gefitinib or erlotinib for the treatment of EGFR-mutated advanced lung adenocarcinoma, with the exclusion of TCM users after tumor progression, were included in this cohort study. Compared with TCM nonuse, TCM use for ≥180 days was associated with a significantly decreased risk of mortality by 68% (adjusted hazard ratio [HR], 0.32 [95% CI, 0.21-0.50], P < .0001). Compared with TCM nonuse, TCM use for ≥180 days was associated with a significantly decreased risk of disease progression by 59% (adjusted HR, 0.41 [95% CI, 0.29-0.58], P < .0001). Conclusion: This cohort study suggests that adjunctive TCM therapy could improve overall survival and progression-free survival in patients with advanced lung adenocarcinoma treated with first-line TKIs. Future randomized, controlled trials are required to validate these findings.

Traditional Chinese medicine decreases the obstructive uropathy risk in uterovaginal prolapse: A nationwide population-based study.

Traditional Chinese medicine (TCM) is a popular treatment for voiding dysfunction in Eastern countries. However, no previous studies have investigated the effects of TCM on preventing obstructive uropathy in uterovaginal prolapse women. We conducted a large-scale nationwide population-based cohort study to investigate the relationship between TCM and obstructive uropathy in uterovaginal prolapse women. This is a retrospective cohort study with the Taiwan National Health Insurance Research Database (NHIRD). The study population was newly diagnosed uterovaginal prolapse patients between 1997 and 2010 year. Among patients, 762 uterovaginal prolapse patients in this cohort. Significant adjusted HRs of urine retention or hydronephrosis in Cox proportional hazard models were uterovaginal prolapse (hazard ratio [HR]: 1.74, 95% confidence intervals [CI]: 1.43–2.14), age 40 to 64 years (1.51, 1.01–2.27), ≥60 years (3.52, 2.32–5.34), DM (1.52, 1.23–1.89), hypertension (1.38, 1.13–1.7), constipation (1.35, 1.05–1.75), urinary tract calculi (1.54, 1.06–2.23), and TCM users (0.34, 0.28–0.41). The Kaplan–Meier analysis showed a higher incidence rate of urine retention or hydronephrosis in the uterovaginal prolapse cohort compared with that of the without uterovaginal prolapse cohort. The results of this nationwide population-based study support a relationship between TCM and a reduced risk of obstructive uropathy in uterovaginal prolapse women.

The Therapeutic Effects of Traditional Chinese Medicine for Poor Semen Quality in Infertile Males.

Poor sperm quality is one of the main factors of male infertility. Traditional Chinese Medicine (TCM) has been used frequently in clinical practice in many countries to treat a wide array of infertile problems. To further understand the effects of TCM on semen quality, we retrospectively enrolled patients with male infertility and poor semen quality at the Tainan Municipal Hospital in Taiwan between 2013 and 2016. Semen quality analysis in accordance with the WHO criteria is an essential step in the evaluation of male fertility status. Associations between the semen parameters and body mass index, smoking status, alcohol use, duration of infertility, and age were also analyzed. A total of 126 male infertility patients with abnormal semen analysis were included in this study: 50 TCM users and 13 TCM non-users. The basic characteristics of the two groups were not significantly different. TCM users account for 92.5% of the total semen improvement subjects. In conclusion, TCM supplementation may have a beneficial role as improving sperm quality for infertility patients.

Traditional Chinese medicine as adjunctive therapy improves the long-term survival of lung cancer patients.

Traditional Chinese medicine is one of the popular alternative treatments for cancer, mainly enhancing host immune response and reducing adverse effect of chemotherapy. This study first explored traditional Chinese medicine treatment effect on long-term survival of lung cancer patients. This study evaluated whether traditional Chinese medicine combined with conventional cancer treatment improved overall survival of lung cancer patients. We had conducted a retrospective cohort study on 111,564 newly diagnosed lung cancer patients in 2000-2009 from National Health Insurance Program database. A total of 23,803 (21.31%) patients used traditional Chinese medicine for lung cancer care. Eligible participants were followed up until 2011 with a mean follow-up period of 1.96years (standard deviation 2.55) for non-TCM users and 3.04years (2.85) for traditional Chinese medicine users. Patients with traditional Chinese medicine utilization were significantly more likely to have a 32% decreased risk of death [hazard ratio=0.62; 95% confidence interval=0.61-0.63], compared with patients without traditional Chinese medicine utilization after multivariate adjustment. We also observed a similar significant reduction risk across various subgroups of chronic lung diseases. Qing Zao Jiu Fei Tang was the most effective traditional Chinese medicine agent for mortality reduction both in the entire lung cancer (0.81; 0.72-0.91) and matched populations (0.86; 0.78-0.95). This study demonstrated adjunctive therapy with traditional Chinese medicine may improve overall survival of lung cancer patients. This study also suggested traditional Chinese medicine may be used as an adjunctive therapy for cancer treatment. These observational findings need being validated by future randomized controlled trials to rule out the possibility of effect due to holistic care.
