A systematic literature review of complementary and alternative medicine prevalence in EU

[Procedures of complementary medicine in rheumatology]

Patients with diseases of the musculoskeletal system are confronted with a large quantity of treatment offers based on methods of complementary medicine. Despite a considerable number of publications on this topic, the scientific evidence is still poor. This article focuses on Ayurvedic medicine (AM), traditional Chinese medicine (TCM), mind-body medicine and homeopathy. These procedures have a longstanding tradition of practice and each claims to have its own theoretical concept; however, the application in the field of rheumatology can only be recommended either for specific entities or, in the case of homeopathy, not at all. In addition, this article summarizes the evidence for dietary recommendations, nutritional supplements and herbal medicine in rheumatology. The latter topics are frequently discussed in the popular press and are a much-debated issue between physicians and patients; however, clear-cut recommendations for the application on a scientific basis are the exception and mainly consist of the endorsement to adhere to the principles of a Mediterranean diet.

Factors influencing the use of natural health products, in particular for concentration and cognition in Germany

BACKGROUND

Natural health products (NHP) are an important part of the healthcare system. They are mainly non-prescription and sold over the counter, which requires active decision making by the consumer. Within the framework of the Complementary and Alternative Healthcare Model, this study aims to identify factors that influence NHP usage, in particular related to concentration and cognition (CC), a topic that concerns all ages and social classes within the population.

METHODS

Data were collected by means of a representative online survey (n = 1,707) in Germany in April 2022. Three user groups were defined: NHPCC users, who used NHP for CC (12 month prevalence); nCC-NHP users, who used NHP but not for CC indications (12 month prevalence); and past NHP users, who have used NHP but not within the previous 12 months. Independent influencing variables were categorized into predisposing, enabling, need, and health service use factors. Data were analyzed with descriptive statistics, inferential statistics, and binary logistic regression models to compare NHPCC users to nCC-NHP users (model 1) and to past NHP users (model 2).

RESULTS

A higher share of NHPCC and nCC-NHP users compared to past NHP users were women, self-medicated with NHP, and used information about NHP provided by health professionals or on product. Their openness-to-change value orientation was more pronounced than of past users. Compared to nCC-NHP and past NHP users, the probability of being an NHPCC user increased if an individual had more difficulties in daily attention and memory performance, made use of health professionals and literature to seek information about NHP, and used NHP for health support and illness prevention. Additionally, a female gender, NHP self-medication, and having higher values of self-transcendence were significant indicators for NHPCC usage compared to past NHP usage.

CONCLUSION

NHP manufacturers, health professionals, and policymakers should be aware of the factors that lead to NHP consumption decisions and consider them in the development and optimization of healthcare strategies as well as in the marketing and communication strategies of companies producing NHP, in particular for CC. The current study can contribute to characterizing the target groups and to defining the aims and communication channels of such campaigns.

How does evidence-based medicine training affect medical students' views on traditional, complementary, and alternative medicine and the conspiracy theories about COVID-19: a nationwide study

AIM

It was aimed to explore the relationship between evidence-based medicine (EBM) training and medical students' views on traditional, complementary, and alternative medicine (TCAM) and their views on conspiracies about COVID-19.

BACKGROUND

Medical students constitute the future workforce of primary health care services. The relationship between EBM training and their views on conspiracies about COVID-19 is critical to explore for providing a better primary health care. The relationship EBM training and medical students' views on TCAM is also important in this regard.

METHODS

This is a cross-sectional study. Turkish medical students were surveyed about EBM training, TCAM, and COVID-19 conspiracies. The electronic survey form consisted of five parts: Demographic characteristics, views and self-perceived knowledge about TCAM and the methods, views on the origin of SARS-COV-2, participation in EBM training, and views on TCAM training. A total of 49 medical schools provided response. Along with descriptive statistics, Chi-square test was utilized.

FINDINGS

Among 2577 participants, 24.0% of them believed SARS-COV-2 was artificially designed. The students who have participated in EBM training via both lecture and small group discussions have a less positive view on TCAM than both the students who have not participated in any EBM training (p < 0.05) and the students who participated in only-lectures (p < 0.05). There was a significant association between EBM training and whether believing COVID-19 (SARS-COV-2) has been designed purposefully by some people or it has emerged naturally χ2 (1) = 17.21 p < 0.001. The odds of thinking COVID-19 emerged naturally was 1.85 times higher (95% CI: 1.38-2.47) if the students have participated in EBM training via both lectures and small group discussions than if they have not participated in any EBM training. EBM training affects medical students in terms of beliefs on COVID-19 conspiracies.

Complementary Medicine in Acute Care Hospitals: Questionnaire Survey with Heads of Bavarian Hospitals

INTRODUCTION

The demand for complementary medicine (CM) is well studied in the outpatient sector, but representative data on type and extent of inpatient care using CM are missing. Therefore, our aim was to examine the range of CM treatments offered and the types of indications for using CM in acute care hospitals in the German state of Bavaria.

METHODS

We conducted a cross-sectional questionnaire survey by contacting the medical heads of all 388 Bavarian acute care hospitals between November 2020 and April 2021. The questionnaire included a wide range of CM to assessed availability of CM supply, most frequent indications, and medical specialities. Furthermore, we assessed basic information about the hospital and the participating medical staff.

RESULTS

A total of 101 (26%) hospitals participated in the survey. At least one CM treatment was offered by 92% of the responding hospitals and 75% offered at least 5 therapy modalities (mean of 10 treatments, range: 0-25). These were most commonly massage therapies (68%), relaxation techniques (63%), phytotherapy (60%), mindfulness-based treatments (53%), art, diet, and exercise therapies (each 48%), aromatherapy (46%), acupuncture, and compresses/poultices (both 42%). The most reported medical conditions for CM treatments (in descending order) were chronic pain, mental disorders, degenerative affections, sleep disorders, fatigue syndrome, functional gastrointestinal disorders, and acute pain.

CONCLUSION

According to the Bavarian acute care hospitals that participated in our postal survey, a considerable part offered CM. Further research should include personal interviews and more detailed assessments of indications and attitudes for the use of CM in acute care hospital settings.

Einleitung

Die Nachfrage nach Komplementärmedizinischen Verfahren (CM) ist für den ambulanten Sektor gut untersucht, aber es fehlen Daten über Art und Umfang der komplementärmedizinischen Versorgung im stationären Bereich. Unser Ziel war es daher, das CM-Angebot und die medizinischen Indikationen in Akutkrankenhäusern im Bundesland Bayern zu untersuchen.

Methoden

Wir führten eine Querschnittsbefragung durch, bei der die klinischen Leitungen aller 388 bayerischen Akutkrankenhäuser zwischen November 2020 und April 2021 angeschrieben wurden. Der Fragebogen inkludierte ein breites Spektrum an CM-Verfahren und erfasste deren Verfügbarkeit, die häufigsten Indikationen und Anwendungsgebiete. Ergänzend wurden grundlegende Informationen des Krankenhauses und des medizinischen Personals erfragt.

Ergebnisse

Insgesamt nahmen 101 (26%) Krankenhäuser an der Befragung teil. Die meisten Ausfüllenden hatten mindestens zwei Jahrzehnte klinische Berufserfahrung. Mindestens eine CM Behandlung wurde von 92% der teilnehmenden Krankenhäuser angeboten und 75% boten mindestens 5 Therapiemodalitäten an (Mittelwert: 10 Behandlungen; Spanne: 0–25). Dabei handelte es sich am häufigsten um Massagen (68%), Entspannungstechniken (63%), Phytotherapie (60%), achtsamkeitsbasierte Behandlungen (53%), Kunst-, Ernährungs-und Bewegungstherapie (jeweils 48%), Aromatherapie (46%), Akupunktur und Kompressen/Umschläge (jeweils 42%). Die häufigsten genannten Indikationen für CM-Behandlungen waren (in absteigender Reihenfolge) chronische Schmerzen, psychische Störungen, degenerative Erkrankungen, Schlafstörungen, Erschöpfungssyndrom, funktionelle Magen-Darm-Beschwerden und akute Schmerzen.

Schlussfolgerung

Nach Angaben der bayerischen Akutkrankenhäuser, die an unserer postalischen Umfrage teilgenommen haben, bietet ein erheblicher Teil CM an. Weitere Untersuchungen sollten persönliche Interviews und detailliertere Bewertungen der Indikationen und Einstellungen für den Einsatz von CM in Akutkrankenhäusern umfassen.

Zhizhu Decoction Alleviates Intestinal Barrier Damage via Regulating SIRT1/FoxO1 Signaling Pathway in Slow Transit Constipation Model Mice

OBJECTIVE

To explore the possible effects and mechanism of Zhizhu Decoction (ZZD) on the pathophysiology of slow transit constipation (STC).

METHODS

A total of 54 C57BL/6 mice was randomly divided into the following 6 groups by a random number table, including control, STC model (model), positive control, and low-, medium- and high-doses ZZD treatment groups (5, 10, 20 g/kg, namely L, M-, and H-ZZD, respectively), 9 mice in each group. Following 2-week treatment, intestinal transport rate (ITR) and fecal water content were determined, and blood and colon tissue samples were collected. Hematoxylin-eosin and periodic acid-Schiff staining were performed to evaluate the morphology of colon tissues and calculate the number of goblet cells. To determine intestinal permeability, serum levels of lipopolysaccharide (LPS), low-density lipoprotein (LDL) and mannose were measured using enzyme-linked immunosorbent assay (ELISA). Western blot analysis was carried out to detect the expression levels of intestinal tight junction proteins zona-occludens-1 (ZO-1), claudin-1, occludin and recombinant mucin 2 (MUC2). The mRNA expression levels of inflammatory cytokines including tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-4, IL-10 and IL-22 were determined using reverse transcription-quantitative reverse transcription reaction. Colon indexes of oxidative stress were measured by ELISA, and protein expression levels of colon silent information regulator 1/forkhead box O transcription factor 1 (SIRT1/FoxO1) antioxidant signaling pathway were detected by Western blot.

RESULTS

Compared with the model group, ITR and fecal moisture were significantly enhanced in STC mice in the M-ZZD and H-ZZD groups (P<0.01). Additionally, ZZD treatment notably increased the thickness of mucosal and muscular tissue, elevated the number of goblet cells in the colon of STC mice, reduced the secretion levels of LPS, LDL and mannose, and upregulated ZO-1, claudin-1, occludin and MUC2 expressions in the colon in a dose-dependent manner, compared with the model group (P<0.05 or P<0.01). In addition, ZZD significantly attenuated intestinal inflammation and oxidative stress and activated the SIRT1/FoxO1 signaling pathway (P<0.05 or P<0.01).

CONCLUSION

ZZD exhibited beneficial effects on the intestinal system of STC mice and alleviated intestinal inflammation and oxidative stress via activating SIRT1/FoxO1 antioxidant signaling pathway in the colon.

National Health Insurance Data Analysis for the Second-Wave Development of Korean Medicine Clinical Practice Guidelines in South Korea

Objectives

After the evidence-based Korean medicine clinical practice guidelines (KM-CPGs) for 30 targeted diseases were developed in 2021, 34 diseases have been proposed for the second-wave development of the KM-CPGs. The purpose of this study was to investigate the development priorities of the candidate diseases into the second-wave development of KM-CPGs in south Korea.

Methods

In this study, we analyzed the Health Insurance Review and Assessment Service National Patient Sample data from 2017 to 2018 to determine the demand and economic importance of the candidates for the second-wave development of KM-CPGs in real-world clinical settings in Korea.

Results

The annual number of visits and patients, annual healthcare expenditure per patient, and healthcare expenditure per institution were analyzed. Musculoskeletal disorders, including sciatica and adhesive capsulitis of the shoulder, were the most important topics regarding the number of visits and patients and annual healthcare expenditure per institution. Specifically, sciatica (52.05% of the total number of visits, 48.34% of the total number of patients, and 42.12% of the total treatment expenditure per institution) showed overwhelmingly high proportions. However, cerebral palsy (36.03% of the total number of inpatient visits and 24.55% of the total number of inpatient patients) was a more important topic in inpatient clinical settings than musculoskeletal conditions or cancer, and healthcare expenditure per patient in this topic had the highest ranking. Furthermore, fractures were found to be highly important in inpatient clinical settings. No patients had influenza A virus infection or posttraumatic stress disorders who visited the KM medical institution of interest.

Conclusion

This study highlights the gap between the real-world clinical setting and the research field in some topics. The results of this study can provide guidance for the second-wave development of KM-CPGs in the future.

Characteristics of Patients Presenting at a University Outpatient Department for Complementary and Integrative Medicine

BACKGROUND

Complementary and integrative medicine (CIM) is increasingly provided at university outpatient departments (OPDs) in Germany, but its scientific evaluation is sparse. Therefore, we aimed to investigate and evaluate feasibility, patients' characteristics and complaints at a university's CIM-OPD.

METHODS

A prospective evaluation included new patients without age restriction. At baseline, and after 6 and 12 months, patients filled out paper questionnaires. Patients rated their mean subjectively perceived severity of the main complaint within the last 7 days on a numerical rating scale (NRS) from 0 = no complaints to 10 = maximum complaints, their perceived resilience capacity in everyday life within the last 7 days (0 = not resilient to 10 = very resilient), and their contentment with the treatment (0 = not content to 10 = very content). Diagnoses were provided by physicians and coded according to the International Statistical Classification of Diseases and Related Health Problems, 10th revision. All data were analyzed descriptively.

RESULTS

During two years, 536 new patients {72.6% response, age (mean ± standard deviation [SD] and range) 49.6 ± 15.8 and 1-86 years, 75.7% female} chose to participate. The most frequent diagnosis groups were neoplasms (C00-C97, n = 143, 18.6%) and musculoskeletal diseases (M00-M99, n = 137, 17.9%). In n = 165 patients (30.8%), more than one diagnosis was provided. In a subgroup of 187 patients, who returned the questionnaire after 6 months, we compared baseline to 6-month values: severity of main complaint (mean ± SD) 5.2 ± 2.6 changed to 3.9 ± 2.6; resilience capacity 5.1 ± 2.6 to 5.6 ± 2.4. After 6 months, respondents rated their contentment with the treatment with (mean ± SD) 7.7 ± 2.6. Data after 12 months (n = 113) are comparable to data after 6 months.

CONCLUSION

Patients of our CIM-OPD had a broad age range, were predominantly female, and suffered mostly from oncologic-related complaints and musculoskeletal diseases. In the responding subgroup after 6 months, patients were content with the treatment. These results should be verified by further prospective evaluations.

Hintergrund

Komplementäre und integrative Medizin (CIM) wird in Deutschland zunehmend in Hochschulambulanzen (OPDs) angeboten, deren wissenschaftliche Evaluation ist jedoch unzureichend. Deshalb war es unser Ziel, die Durchführbarkeit einer Evaluation, die Charakteristika und die Beschwerden der Patienten und Patientinnen an einer CIM-ODP zu untersuchen.

Methoden

Eine prospektive Evaluation schloss neue Patienten und Patientinnen ohne Altersbeschränkung ein. Zu Baseline sowie nach sechs und 12 Monaten füllten die Patienten und Patientinnen Papierfragebögen aus. Die Patienten und Patientinnen bewerteten ihre mittlere subjektiv empfundene Schwere der Hauptbeschwerden in den letzten sieben Tagen auf einer numerischen Ratingskala (NRS) von 0 = keine Beschwerden bis 10 = maximale Beschwerden, ihre mittlere subjektiv empfundene Belastbarkeit im Alltag in den letzten sieben Tagen (0 = nicht belastbar bis 10 = sehr belastbar) und ihre Zufriedenheit mit der Behandlung (0 = nicht zufrieden bis 10 = sehr zufrieden). Die Diagnosen wurden von den Ärzten und Ärztinnen gestellt und nach der International Statistical Classification of Diseases and Related Health Problems, 10. Revision, kodiert. Die Daten wurden deskriptiv ausgewertet.

Ergebnisse

Im Laufe von zwei Jahren nahmen 536 neue Patienten und Patientinnen (72.6% Rücklauf, Alter (Mittelwert ± SD und Range) 49.6 ± 15.8 und 1–86 Jahre, 75.7% weiblich) teil. Die häufigsten Diagnosen waren Neoplasmen (C00-C97, n = 143, 18.6%) und Erkrankungen des Bewegungsapparates (M00-M99, n = 137, 17.9%). Bei n = 165 (30.8%) Patienten und Patientinnen wurde mehr als eine Diagnose vergeben. In einer Subgruppe von 187 Patienten und Patientinnen, die den Fragebogen nach 6 Monaten zurücksendeten, verglichen wir die Ausgangs-und 6-Monats-Werte: Schweregrad der Hauptbeschwerden (Mittelwert±SD) 5.2 ± 2.6 veränderte sich zu 3.9 ± 2.6; Belastbarkeit 5.1 ± 2.6 zu 5.6 ± 2.4. Nach sechs Monaten bewerteten die Befragten ihre Zufriedenheit mit der Behandlung mit (Mittelwert±SD) 7.7 ± 2.6. Die Daten nach 12 Monaten (n = 113) sind mit den Daten nach 6 Monaten vergleichbar.

Schlussfolgerung

Die Patienten und Patientinnen unserer CIM-OPD hatten eine breite Altersspanne, überwiegend weiblich und litten zumeist unter onkologisch bedingten Beschwerden und Erkrankungen des Bewegungsapparates. Patienten und Patientinnen der nach sechs Monaten antwortenden Subgruppe waren mit der Behandlung zufrieden. Die Ergebnisse sollten durch weitere prospektive Evaluationen verifiziert werden.

Foot Reflexology: Recent Research Trends and Prospects

Foot reflexology is a non-invasive complementary therapy that is increasingly being accepted by modern people in recent years. To understand the research trends and prospects of foot reflexology in the past 31 years, this study used the Web of Science core collection as the data source and two visualization tools, COOC and VOSviewer, to analyze the literature related to the field of foot reflexology from 1991 to 2021. This study found that the number of articles published in the field of foot reflexology has been increasing year by year, and the top three journals with the most articles are Complementary Therapies in Clinical Practice, Therapies in Medicine, and the Journal of Alternative and Complementary Medicine. The top three most prolific authors are Wyatt, Sikorskii, and Victorson, and the core institutions in the field of foot reflexology are Michigan State University, Northwestern University, Tehran University of Medical Sciences, and the University of Exeter. Foot reflexology has been shown to have a moderating effect on anxiety, fatigue, and cancer, and is a topic of ongoing and future research. This study uses this bibliometric analysis of foot reflexology literature to provide an overview of prior knowledge and a reference direction for modern preventive medicine.

Use of complementary and alternative medicine (CAM) in patients with inflammatory bowel disease (IBD): results from a German nationwide survey of 2019 compared to a previous survey of 2002

INTRODUCTION

In 2002, 50% of patients with Inflammatory Bowel Disease (IBD) had used complementary and alternative medicine (CAM) in Germany. This survey aimed to examine changes from 2002 to 2019 and predictors of CAM use in 2019.

MATERIALS AND METHODS

In 2019, a questionnaire was sent randomly to 1000 members of the German Crohn's Colitis Association, the same sampling strategy was chosen 2002. Items assessed included, demographic characteristics, IBD diagnosis and disease history, medication use, patients' symptoms/quality of life, anxiety/depression and use of complementary therapies.

RESULTS

The 2019 sample only differed slightly in case of gender (55% women) and disease (43% Ulcerative Colitis) from the 2002 sample. In 2019, 54% (227/417) reported having ever used CAM and 75% (396/417) planned to use CAM for their IBD in the future, whereby there was an evidence of a decrease in exclusive CAM use from 2002 (28%; 96/344) to 2019 (16%, 37/277; BF<.01). In logistic regression analyses, ulcerative colitis compared to Crohn's Disease (OR 0.59, p=.005), side effects of standard therapy (OR 1.94, p=.012), the use of corticosteroids (OR 0.54, p=.038) or biologics (OR 1.90, p = .020) and lower quality of life (OR 0.96, p=.002) were associated with CAM use in 2019.

CONCLUSIONS

Every other patient with IBD used CAM and has thus indicated a need for a safe and evidence-based combination of conventional and complementary approaches. This would further support the desired decrease in exclusive -alternative- CAM use.

A Japanese Herbal Formula, Daikenchuto, Alleviates Experimental Colitis by Reshaping Microbial Profiles and Enhancing Group 3 Innate Lymphoid Cells

Daikenchuto (DKT) is one of the most widely used Japanese herbal formulae for various gastrointestinal disorders. It consists of Zanthoxylum Fructus (Japanese pepper), Zingiberis Siccatum Rhizoma (processed ginger), Ginseng radix, and maltose powder. However, the use of DKT in clinical settings is still controversial due to the limited molecular evidence and largely unknown therapeutic effects. Here, we investigated the anti-inflammatory actions of DKT in the dextran sodium sulfate (DSS)-induced colitis model in mice. We observed that DKT remarkably attenuated the severity of experimental colitis while maintaining the members of the symbiotic microbiota such as family Lactobacillaceae and increasing levels of propionate, an immunomodulatory microbial metabolite, in the colon. DKT also protected colonic epithelial integrity by upregulating the fucosyltransferase gene Fut2 and the antimicrobial peptide gene Reg3g. More remarkably, DKT restored the reduced colonic group 3 innate lymphoid cells (ILC3s), mainly RORγt^high-ILC3s, in DSS-induced colitis. We further demonstrated that ILC3-deficient mice showed increased mortality during experimental colitis, suggesting that ILC3s play a protective function on colonic inflammation. These findings demonstrate that DKT possesses anti-inflammatory activity, partly via ILC3 function, to maintain the colonic microenvironment. Our study also provides insights into the molecular basis of herbal medicine effects, promotes more profound mechanistic studies towards herbal formulae and contributes to future drug development.

Operational definition of complementary, alternative, and integrative medicine derived from a systematic search

BACKGROUND

Identifying what therapies constitute complementary, alternative, and/or integrative medicine (CAIM) is complex for a multitude of reasons. An operational definition is dynamic, and changes based on both historical time period and geographical location whereby many jurisdictions may integrate or consider their traditional system(s) of medicine as conventional care. To date, only one operational definition of "complementary and alternative medicine" has been proposed, by Cochrane researchers in 2011. This definition is not only over a decade old but also did not use systematic methods to compile the therapies. Furthermore, it did not capture the concept "integrative medicine", which is an increasingly popular aspect of the use of complementary therapies in practice. An updated operational definition reflective of CAIM is warranted given the rapidly increasing body of CAIM research literature published each year.

METHODS

Four peer-reviewed or otherwise quality-assessed information resource types were used to inform the development of the operational definition: peer-reviewed articles resulting from searches across seven academic databases (MEDLINE, EMBASE, AMED, PsycINFO, CINAHL, Scopus and Web of Science); the "aims and scope" webpages of peer-reviewed CAIM journals; CAIM entries found in online encyclopedias, and highly-ranked websites identified through searches of CAIM-related terms on HONcode. Screening of eligible resources, and data extraction of CAIM therapies across them, were each conducted independently and in duplicate. CAIM therapies across eligible sources were deduplicated.

RESULTS

A total of 101 eligible resources were identified: peer-reviewed articles (n = 19), journal "aims and scope" webpages (n = 22), encyclopedia entries (n = 11), and HONcode-searched websites (n = 49). Six hundred four unique CAIM terms were included in this operational definition.

CONCLUSIONS

This updated operational definition is the first to be informed by systematic methods, and could support the harmonization of CAIM-related research through the provision of a standard of classification, as well as support improved collaboration between different research groups.

Therapy-dependent inconsistencies in self-reported use of complementary and alternative medicine in the general population: findings from a longitudinal study

OBJECTIVE

Information on the use of complementary and alternative medicine (CAM) in the general population is often collected by means of surveys, causing the reliability of data to rely on the memory accuracy of the respondent. The objective of this study was to examine the consistency in self-reported CAM use using data from two survey waves 4 years apart.

DESIGN

Longitudinal study.

SETTING/PARTICIPANTS

Data were obtained from the Danish Health and Morbidity Surveys. A nationally representative subsample of the individuals invited in 2013 was reinvited in 2017. In all, 2297 individuals (≥16 years) completed the self-administered questionnaire in both waves, including questions on for example, CAM use.

MAIN OUTCOME MEASURES

The use of six different CAM therapies (acupuncture; craniosacral therapy; faith healing and/or clairvoyance; nutritional counselling; massage; osteopathy or other manipulative therapies; reflexology) was assessed by the response categories 'Yes, within the past 12 months', 'Yes, but previously than within the past 12 months' and 'No'. For each CAM therapy, an inconsistent response was defined as either the response combination (1) 'Yes, within the past 12 months' in 2013 and 'No' in 2017, or (2) 'Yes, within the past 12 months' or 'Yes, but previously than within the past 12 months' in 2013 and 'No' in 2017.

RESULTS

The inconsistency percentages varied across CAM therapies. The highest levels of inconsistency for CAM use within the past 12 months were observed for nutritional counselling (64.9 %) and faith healing and/or clairvoyance (36.4 %). The lowest proportion of inconsistent responses was observed for acupuncture (18.3%). Overall, the same pattern was observed for lifetime CAM use.

CONCLUSIONS

The results highlight the difficulty in obtaining reliable prevalence estimates on the use of CAM in the general population. Future studies should take these findings into account when interpreting similar analyses.

Integration of complementary and integrative medicine competencies in general practice postgraduate education - development of a novel competency catalogue in Germany

Background

Complementary and integrative medical procedures (CIM) play an important role in general practice (GP). Consequently, in some countries (e.g. USA, Australia) specific curricula for the integration of CIM competencies in GP postgraduate education exist. Although Germany is one of the countries where CIM is strongly integrated in general practice, no such catalogue exists up to date. The aim of this study was to define a set of CIM competencies that are seen as relevant and feasible for postgraduate education in the German general practice setting.

Methods

We used a multi-step, peer-based approach combining four different steps. Firstly, a survey among GP trainees (n = 138) was performed in order to assess needs and attitudes towards CIM. Then, existing competency-based CIM curricula were identified in international literature, translated into German and compared with the needs assessment from the survey. In a next step, we performed a survey among the CIM working group of the German Society for General Medicine and Family Medicine (DEGAM). As a last step, in a peer-based survey, GP trainers, GP trainees, and members of professional CIM associations (n = 131) evaluated a list of CIM competencies according to relevance and feasibility for general practice.

Results

Within this multistage process, a final catalogue of 16 competencies was defined, covering the following areas: Medical knowledge, patient care and communication, practice-based learning, professionalism, and competencies based on the German healthcare system.

Conclusion

The final catalogue of CIM competencies is intended to serve for GP training complementing the German competency-based curriculum for general practice. These competencies cover basic skills and are not intended to replace existing additional qualifications awarded by the medical associations in specific CIM methods, such as acupuncture or manual medicine. Therefore, a list of relevant competencies on CIM is available in order to serve as add-on for postgraduate education in general practice in Germany.

The Attitude of Medical Students Toward Complementary Medicine: Results of a Cross-Sectional Study

Introduction: Complementary medicine (CM) is often used by patients and offered by physicians. The attitude of medical students toward CM in Germany has been given little research attention. The aim was to assess the attitude of medical students toward CM in general and their opinion about the importance of CM university research and teaching.

Methods: An exploratory cross-sectional study among medical students at the Charité—Universitätsmedizin Berlin was performed at the beginning of the summer term 2019 using an online survey. The attitude toward CM was assessed by the Complementary and Alternative Medicine Health Belief Questionnaire (CHBQ, range 10–70, neutral at 40; a higher score indicates a more positive attitude toward CM). Furthermore, students rated their own CM use and the perceived importance of CM university research and teaching (range 1–7; a higher score indicates more agreement). The study was approved by the Charité Ethics Committee (institutional review board).

Results: Out of 1256 contacted students, 349 (27.8%) students (mean age 23.7 ± 4.3 years, 69.0% female) participated. The attitude toward CM based on the CHBQ was rather neutral (mean 44.2 ± 10.7) and more positive among females than males (mean 46.1 ± 10.7 vs. 40.6 ± 9.5, p < 0.001). Medical students favored CM university research (mean 5.4 ± 1.5) and mostly did not agree that CM is currently taught sufficiently at the university (mean 3.4 ± 1.7). The lifetime prevalence of student's own CM use was 48.4% of respondents (79.1% females).

Conclusion: Although medical students, in this sample with a high percentage of females, reported a rather neutral attitude toward CM, the authors' findings indicate that medical students promoted research and teaching in CM. Further multicenter cross-sectional studies in German and European medical universities should be undertaken to explore students' attitudes and wishes regarding the integration of CM in university teaching, research, and patient care.

[Naturopathy and complementary medicine in small animal science - definitions and contents]

Naturopathic and complementary procedures attain increasing popularity in veterinary medicine. A common understanding of definitions and contents of these fields is crucial for communication between pet owners and veterinarians. This paper reviews the existing definitions and the various contents of naturopathy and complementary veterinary medicine as well as their assigned treatment options. Naturopathy includes phytotherapy, hydro-therapy, thermotherapy, electrotherapy, manual therapy/chiropractic/osteopathy, and dietetic treatment. Homeopathy, homotoxicology, Traditional Chinese Medicine including acu-puncture and Chinese herbal medicine, neural therapy, organotherapy and Bach flower remedies are known as complementary treatments. The level of evidence based on scientific literature and the opportunity for certification procedures differ between treatment modalities. In the area of small animal medicine, the most extensive body of literature is available on the subject of acupuncture, in part comprising high evidence levels.

Complementary and alternative medicine use among older adults with musculoskeletal pain: findings from the European Social Survey (2014) special module on the social determinants of health

Background:

This study describes the use of complementary and alternative medicine (CAM) among older adults who report being hampered in daily activities due to musculoskeletal pain. The characteristics of older adults with debilitating musculoskeletal pain who report CAM use is also examined.

Methods:

Cross-sectional European Social Survey Round 7 data from 21 countries were examined for participants aged 55 years and older, who reported musculoskeletal pain that hampered daily activities in the past 12 months.

Results:

Of the 4950 older adult participants reporting musculoskeletal pain that hampered daily activities, the majority (63.5%) were from the West of Europe, reported secondary education or less (78.2%), and reported at least one other health-related problem (74.6%). In total, 1657 (33.5%) reported using at least one CAM treatment in the previous year. Manual body-based therapies (MBBTs) were most used, including massage therapy (17.9%) and osteopathy (7.0%). Alternative medicinal systems (AMSs) were also popular with 6.5% using homoeopathy and 5.3% reporting herbal treatments. A general trend of higher CAM use in younger participants was noted. CAM use was associated with physiotherapy use, female gender, higher levels of education, being in employment and living in West Europe. Those reporting multiple health problems were more likely to use all CAM treatments, except MBBT.

Conclusion:

A third of older Europeans with musculoskeletal pain report CAM use in the previous 12 months. Certain subgroups with higher rates of CAM use could be identified. Clinicians should comprehensively and routinely assess CAM use among older adults with musculoskeletal pain.

Traditional, complementary and integrative medicine use among Indigenous peoples with diabetes in Australia, Canada, New Zealand and the United States

OBJECTIVE

This systematic review aimed to describe traditional, complementary and integrative medicine (TCIM) use among Indigenous peoples with diabetes from Australia, Canada, New Zealand and the United States (US).

METHODS

A systematic search following the PRISMA (Preferred Reporting Items for Systematic Reviews and MetaAnalyses) statement guidelines was conducted. Data were analysed using meta-aggregation.

RESULTS

Thirteen journal articles from 12 studies across Australia, Canada and the US were included in the review (no articles from New Zealand were identified). Indigenous peoples used various types of TCIM alongside conventional treatment for diabetes, particularly when conventional treatment did not meet Indigenous peoples' holistic understandings of wellness. TCIM provided opportunities to practice important cultural and spiritual activities. While TCIM was often viewed as an effective treatment through bringing balance to the body, definitions of treatments that comprise safe and effective TCIM use were lacking in the articles.

CONCLUSIONS

The concurrent use of TCIM and conventional treatments is common among Indigenous peoples with diabetes, but clear definitions of safe and effective TCIM use are lacking. Implications for public health: Healthcare providers should support Indigenous peoples to safely and effectively treat diabetes with TCIM alongside conventional treatment.

A cross-sectional workforce survey of three traditional and complementary medicine professions in Ontario, Canada

BACKGROUND

Workforce studies about traditional and complementary medicine (T&CM) occupations in industrialized countries are scant; and, these occupations' position within the broader occupational workforce remains unclear. This study aims to address these gaps using a comparative approach.

METHODS

Naturopaths, traditional Chinese medicine (TCM) / acupuncture practitioners, and homeopaths in Ontario, Canada were surveyed regarding their demographics, practice characteristics and self-reported income. Results were compared with parallel data from within and outside of Ontario.

RESULTS

Study response rate: 23.3% (n = 1205). While predominantly female (57.9%), Ontario's TCM/acupuncture profession was less feminized than the naturopathic (77.1%) and homeopathic (78.3%) groups. Naturopaths were significantly younger than, and reported fewer years of clinical experience than, the other two groups. About half of TCM/acupuncture practitioners, and almost one-third of homeopaths had trained outside of Canada, predominantly in East and South Asia, respectively. More TCM/acupuncture practitioners (58.9%) and homeopaths (57.6%) had multilingual clinical practices than naturopaths (19.1%). Homeopaths worked fewer hours and saw fewer patients per week than the other occupations. Self-reported mean incomes varied across groups, with naturopaths earning more on average ($63,834, SD $57,101) than did TCM/acupuncture practitioners ($45,624, SD $44,081) or homeopaths ($29,230, SD $41,645). Holding other variables constant, internationally-trained practitioners reported earning one-third less than their Canadian-trained counterparts.

DISCUSSION & CONCLUSIONS

Study findings echo occupationally-specific data from other industrialized jurisdictions; and, affirm that different T&CM occupations have distinctive demographic and practice characteristics. The demographic makeup of Ontario's TCM/acupuncture and homeopathy occupations suggests a role for these groups in delivering culturally-responsive care within Asian ethnic communities. T&CM practitioner incomes, in particular for internationally-trained practitioners, fell below the provincial population income median, and in many cases below the poverty line. T&CM occupations' relative socio-political marginality may be impacting clinicians' ability to earn a viable living.

Medicinal Plants and Mushrooms with Immunomodulatory and Anticancer Properties-A Review on Hong Kong's Experience

The immune modulating effects of selected herbs deserve careful studies to gain evidence-based support for their further development. We have been working hard on many items of medicinal herbs to gain insight into their immunomodulatory effects relevant to cancer treatment in particular, while infection control is not excluded. Nine of them have been selected to give the results of our exploration on their biological, particularly immunomodulatory activities. Since Hong Kong people especially favor one medicinal mushroom, viz. Coriolus versicolor, a number of clinical trials using Coriolus for cancer-related studies are included in this review. While immune modulation platforms are being built for relevant studies, a brief account on the research targets and related procedures are given.

The prevalence of complementary and alternative medicine use in the general population of Babol, North of Iran, 2018

Background

Complementary and Alternative Medicine (CAM) have recently become more popular and accepted worldwide. One principal step to identify the status and organize strategies of CAM is evaluating the manner and the prevalence of its usage among people. This study aimed to investigate the prevalence of CAM modalities usage by the people of Babol, a central city in the North of Iran, in 2018.

Methods

Using the original International CAM Questionnaire (I-CAM-Q), a questionnaire was redesigned in Persian (Farsi) with some changes such as adding special modalities in Iran and its validity and reliability were assessed. Six hundred households were evaluated using a cluster sampling method in 2018 spring by 12 trained interviewers.

Results

Finally, 1770 questionnaires were correctly completed. A total of 110 participants (6.21% of the completed questionnaires) had visited CAM therapists in the last year, 109 persons (6.15%) had received prescriptions from physicians and paramedics to use CAM, and a total of 1032 people (58.30%) used herbs and herbal medicines in the last 12 months. Also, 1265 individuals (71.46%) had used CAM throughout their lives. The most popular methods were herbal medicine (65.76%), Persian Medicine (13.78%), water therapy (10.45%) and music therapy (8.36%). The use of CAM was more popular among women.

Conclusions

The general use of CAM in Babol was similar to other studies, but there were fewer visits by CAM therapists and less frequent adoption of common methods including homeopathy, acupuncture, and energy therapy. It was found that CAM was mostly used for non-serious diseases such as cold and transient gastrointestinal disorders, a pattern that is different from other studies in this field.

Patterns and predictors of complementary and alternative medicine use in people presenting with the non-communicable disease in an urban health facility, North India

Background: The rising burden of non-communicable diseases (NCDs) is a threat to India. Increasingly, individuals interested in improving their health and making healthy lifestyle changes are turning to complementary and alternative medicine (CAM) as a health-care option.

Design and Methods: The objective of this study was to determine the prevalence, pattern, and predictor of alternative medicine use among NCDs patients undergoing allopathic treatment in an urban health centre. The study design was a hospital-based crosssectional study, which was done in a government hospital, Srinagar, Pauri District, Uttarakhand, India among adult males and females aged above 20 years. The patients having NCDs were systematically sampled.

Result: Among 233 studied patients 57.1% were males. The mean age of the patients was 55.8 years (SD 13.5). Of the total studied patients 46.8% were diagnosed with DM, and 43.8% of HTN. Nearly one-fifth of the patients were known to have a CVD or COPD. A total of 49.8% of the studied NCD patients reported use of both allopathic and alternative medicine treatment and nearly 3.4% of the studied NCD patients in the last one year to seek exclusive alternative medicine treatment. The overall use of exclusive alternative medicine was low that is 3.7%, 1.0%, and 5% in diabetes, hypertension, and chronic lung disease patients, respectively. The most common form of alternative medicine used by studied patients was medicinal herbs/biological-based medicine (MB) (62.9%). Among MB commonly used were a bitter gourd, aloe vera, and others. 29.8% of the patients used Indian/Ayurveda medicine in total.

Conclusions: The use of exclusive alternative medicine is low in adult patients with NCD. However, medical pluralism is prevalent. A better understanding of practices especially that focuses on alternative medicine needs a qualitative study, which was beyond the scope of this study.

Use of complementary and alternative therapies by patients with eye diseases: a hospital-based cross-sectional study from Palestine

BACKGROUND

Generally, complementary and alternative therapies (CAT) are accepted methods of treatment by patients with various types of conditions. Their use is becoming especially prevalent among patients with eye problems even in developed countries. Thus, we aimed to determine the pattern of use of CAT in this patient population, to identify the patient characteristics associated with the use of CAT, and to assess the types of CAT used.

METHODS

A descriptive, cross-sectional study was conducted in Palestine at An-Najah National University Hospital between the time periods of October 2019 to May 2020, using questionnaire-based face to face interviews. Data were collected through convenience sampling. Patients responded to the questionnaire, which was focused on information adapted from previous research in this area, covering socio-demographic and clinical characteristics, types of CAT, source of information, and side effects on CAT use.

RESULTS

A total of 86 patients were interviewed for our study. Over two thirds, 67% reported using CAT for the specific purpose of improving their eye condition, and about one third (29.1%) received more than one therapy. The most common therapies reported were duea' (i.e. supplication) (47.1%) and herbal therapies (24.1%). It was shown that patients with bilateral involvement of their eyes were almost twice more likely to describe using CAT than patients with unilateral eye pathology (p = 0.006). Also, patients who underwent surgery as their route of treatment were significantly less likely to use CAT (p = 0.043). Most of our study participants mentioned a non-physician source as their source of information regarding CAT with family members being the most frequently mentioned (30.2%) followed by the internet (25.6%) and friends (19.8%).

CONCLUSIONS

The prevalence of CAT use among patients with eye disease is somewhat high in our study population. Because CAT may trigger adverse reactions, influence the progression of the disease, and interfere with conventional treatment, the ophthalmologist should frequently be asked patients with such diagnostics regarding the use of these therapies. Further work is required to analyze the mechanisms of action and to establish realistic guidelines for the use of these modalities.

Potential factors that influence usage of complementary and alternative medicine worldwide: a systematic review

OBJECTIVES

To determine similarities and differences in the reasons for using or not using complementary and alternative medicine (CAM) amongst general and condition-specific populations, and amongst populations in each region of the globe.

METHODS

A literature search was performed on Pubmed, ScienceDirect and EMBASE.

KEYWORDS

'herbal medicine' OR 'herbal and dietary supplement' OR 'complementary and alternative medicine' AND 'reason' OR 'attitude'. Quantitative or qualitative original articles in English, published between 2003 and 2018 were reviewed. Conference proceedings, pilot studies, protocols, letters, and reviews were excluded. Papers were appraised using valid tools and a 'risk of bias' assessment was also performed. Thematic analysis was conducted. Reasons were coded in each paper, then codes were grouped into categories. If several categories reported similar reasons, these were combined into a theme. Themes were then analysed using χ2 tests to identify the main factors related to reasons for CAM usage.

RESULTS

231 publications were included. Reasons for CAM use amongst general and condition-specific populations were similar. The top three reasons for CAM use were: (1) having an expectation of benefits of CAM (84% of publications), (2) dissatisfaction with conventional medicine (37%) and (3) the perceived safety of CAM (37%). Internal health locus of control as an influencing factor was more likely to be reported in Western populations, whereas the social networks was a common factor amongst Asian populations (p < 0.05). Affordability, easy access to CAM and tradition were significant factors amongst African populations (p < 0.05). Negative attitudes towards CAM and satisfaction with conventional medicine (CM) were the main reasons for non-use (p < 0.05).

CONCLUSIONS

Dissatisfaction with CM and positive attitudes toward CAM, motivate people to use CAM. In contrast, satisfaction with CM and negative attitudes towards CAM are the main reasons for non-use.

Exploring socioeconomic inequalities in the use of medicinal herbs among Iranian households: evidence from a national cross-sectional survey

Background

Association between socioeconomic status and medicinal herbs (MH) are rarely documented in Iran. Our goal was to measure and decompose socioeconomic inequalities in MH use among Iranian households.

Methods

The data used in this cross-sectional study were extracted from the 2018 Household Income and Expenditure Survey (HIES) (N = 38,859). Data on MH use, age, gender, and education status of the head of household; a constructed wealth index of household (as a proxy for household’s socioeconomic status); and place of residence (urban or rural) were obtained from the survey. Publicly available province-level data on Human Development Index (HDI) were obtained from the Institute for Management Research at Radbound University. We used the concentration curve and the normalized concentration index (C_n) to measure the magnitude of socioeconomic inequalities in MH among Iranian households. The C_n was decomposed to identify the main determinants of socioeconomic inequalities in MH in Iran.

Results

The overall prevalence of MH use among Iranian households was 4.7% (95% confidence interval [CI]: 4.5 to 4.9%) in the last month before data collection. The C_n for MH use for the whole of samples was 0.1519; 95% CI = 0.1254 to 0.1784; suggesting a higher concentration of MH use among the households with high socioeconomic level. The decomposition analysis indicated that the main contributing factors to the concentration of MH use were the economic status of households, development status of the province, and education level of the household head.

Conclusions

This study demonstrated that MH use is more concentrated among socioeconomically advantaged households in Iran and its provinces. This finding might contrast with the widespread belief that wealthy and socioeconomically advantaged populations, compared to low SES groups, tend to seek disproportionately more modern medical treatments and medications than MH. Understanding the factors affecting MH use, socioeconomic inequality in use of MH and its determinants provide an opportunity for health policymakers to design effective evidence-based interventions among providers and consumers of MH.

Is it safe to consume traditional medicinal plants during pregnancy?

The popularity of natural medicine is growing worldwide. Unlike conventional licensed medicines, herbal medicine practices are usually not supported by effectiveness, efficacy, or safety studies, which raise concerns about potential risks involved in their usage, particularly in high-risk patients such as pregnant women where teratogenicity is a concern. Despite a lack of science-based evidence, the use of herbal products for the management of pregnancy-associated challenges is common, due to the common notion that they are free of toxic effects and adverse reactions because they are "natural." The lack of concern about utilizing herbal remedies during pregnancy is strengthened by the lack of regulation in most countries for their marketing. However, plant-based remedies are not free of adverse reactions. Medicinal plants and herbal remedies contain substances that can be toxic to the human body and the fetus. Potential effects of indiscriminate use of medicinal plants are embryotoxicity, teratogenic, and abortifacient effects. Some plant constituents can cross the placenta and reach the fetus. Phytochemicals and their metabolites are known to induce stimulation of uterine contraction and hormone imbalance that could result in abortion. The alterations to the hormonal profile can affect conception, induce teratogenic activity, and halt the pregnancy or produce a congenital malformation. Due to the wide range of modes of action of phytochemicals, some medicinal plants may be safe to use during certain trimesters of pregnancy and harmful at other stages. This manuscript reviews available scientific information concerning potential health hazards associated with the consumption of herbal medicines during pregnancy, highlighting those herbs that should be avoided due to their potential abortifacient and/or teratogenic activity. We focused on plants that were tested by preclinical studies, and studies of these plants are summarized. Common therapeutic use of these herbs, estimated effects, toxicological effects, and animal studies of these plants is summarized. The literature reviewed suggests that consumption of the following medicinal plants should be avoided during pregnancy: Abrus precatorius, Achyranthes aspera, Ailanthus excelsa, Aloe vera, Aristolochia indica, Areca catechu, Bambusa vulgaris, Cassia occidentalis, Cicer arietinum, Cimicifuga racemose, Dolichandrone falcate, Ginkgo biloba, Hydrastis canadensis, Indigofera trifoliate, Lavandula latifolia, Maytenus ilicifolia, Momordica cymbalaria, Moringa oleifera, Musa rosacea, Oxalis corniculate, Phytolacca dodecandra, Plumeria rubra, Ricinus communis, Ruta graveolens, Stachys lavandulifolia, Senna alata, Trigonella foenum-graecum, Vitus agnus-castus, and Valeriana officinalis.

The Use of Complementary and Alternative Medicine (CAM) in Psychiatric Units in Sweden

Mental ill-health has been termed the pandemic of the 21^st century, and a large share of those exposed do not receive treatment. Many people with depression, anxiety and other mental health problems consult complementary or alternative medicine (CAM), and CAM is used in conventional psychiatric care, in Sweden and in other countries. However, the extent to which CAM is used in psychiatric care, and for what purposes, are largely unknown. This study is based on a survey distributed to all heads of regional, municipal, private and governmental health care units treating persons with psychiatric symptoms across Sweden in 2019. CAM was reportedly used by 62% of the 489 responding health care units, for symptoms including anxiety, sleep disturbances and depression. Main motivations for CAM use were symptom relief, meeting patients' requests and reduced demand for pharmaceutical medication. Very few respondents reported side effects. The most common reason for interrupting CAM use at a unit was a lack of trained professionals. This study confirms the need for further research about CAM, and for CAM education and training among healthcare professionals.

The relationship between health sciences students' perceptions of health news and their attitudes to using complementary and alternative medicine

PURPOSE

Written-visual and social media play a significant role in accessing knowledge about health issues. Media coverage of complementary and alternative medicine (CAM) can affect the beliefs, attitudes, behaviors and decisions to use of CAM the individuals. The research was planned as a descriptive, cross-sectional study was to evaluate the relationship between the health sciences students' perceptions of health news and their attitude towards using CAM.

METHOD

The sample included 736 students studying in a Department of Nursing, Physiotherapy and Rehabilitation, and Nutrition and Dietetics program in a Faculty of Health Sciences. A Students' Description Form, The Perception of Health News Scale (PHNS), and The Attitude towards Using Complementary Treatments Scale (ACTS) were used to collect the data in this study.

RESULTS

The students' mean PHNS scores were found to be 81.05 ± 13.42, and their mean ACTS scores were 30.07 ± 6.56. There was a statistically significant difference between HS students' mean PHMS scores and usage of CAM and following of health news on the written-visual media (p < 0.05). There was a statistically significant difference between HS students' mean ACTS scores and their department of study, year of study, usage of CAM, education on CAM, usage of social media, following of health news on the written-visual media and following health news on social media (p < 0.05). A weak positive correlation was found between the students' PHNS scores and their ACTS scores (r = 0.189, p = 0.000).

CONCLUSION

In the conclusion of our research, it was found that HS students' perception of health news may affect their attitudes towards using CAM.

Use of Complementary and Alternative Medicine among Young Patients with Breast Cancer

BACKGROUND

Complementary and alternative medicine (CAM) has received increasing attention in Western countries and is especially common among breast cancer (BC) patients. So far, its effectiveness has not been well studied, which is in part due to the contextuality of CAM along with a lack of information of why patients use it.

OBJECTIVES

Young BC patients constitute a special patient group regarding clinical characteristics, QOL, and their role in society. Since little is known about their CAM use, this study aimed at exploring it as well as their reasons for CAM use.

METHODS

Data on CAM and sociodemographics were collected via questionnaire in the context of a rehabilitation program for young mothers with BC. Initial BC diagnoses were between 2009 and 2014 (recruitment period 2012-2015). Clinical characteristics were derived from the patient files. Descriptive statistics were used to describe frequencies and statistically significant differences were tested.

RESULTS

Among the 827 patients, with an average age of 39.6 years, 62.5% had used CAM with regard to their cancer. CAM use was significantly higher in women with higher educational level, higher employment status, and statutory health insurance, respectively. The average monthly expenses on CAM were EUR 50. Every 5th woman used CAM without her physician's knowledge. The types most often used were dietary supplements with vitamins or minerals. The most frequent reasons for CAM use were to strengthen the immune system, support conventional medicine, and combat side effects.

CONCLUSIONS

CAM plays an important role for young BC patients with regard to prevalence and monthly expenses, and was used for a wide range of reasons. Certain subgroups with more frequent CAM use could be identified. Physicians should therefore proactively talk about CAM with their young BC patients, so that patients do not need to rely on information sources on CAM outside the medical system.

A multi-centre, parallel-group, randomised controlled trial to assess the efficacy and safety of eurythmy therapy and tai chi in comparison with standard care in chronically ill elderly patients with increased risk of falling (ENTAiER): a trial protocol

BACKGROUND

In elderly poeple, multimorbidity and polypharmacy increase while sensory, motor and cognitive functions decrease. Falls occur in 30% of people aged 65 years and older at least once per year, with injuries at 10-20%. Reducing falls and enhancing physical, emotional and cognitive capacities are essential for healthy aging despite chronic disease. Eurythmy therapy (EYT) and Tai Chi train balance, mobility and concentrative and sensory capacities.

METHODS

In eight trial sites (academic or community hospitals), 550 outpatients aged 65 years and older with chronic disease and increased risk of falling (history of imbalance, Berg Balance Scale (BBS) score ≤ 49) will be randomly assigned (1:1:1) to receive either EYT or Tai Chi (each provided in one-hour group sessions, twice, later once per week plus practice at home, for over 24 weeks) added to standard care or standard care alone. Standard care includes a detailed written recommendation on fall prevention and the visit of a primary care doctor. Seniors living a reclusive life or economically disadvantaged elderly will be particularly addressed. A motivation and communication concept supports the trial participants' compliance with trial procedures and practicing. Public and patient representatives are involved in the planning and conduction of the trial. Falls will be documented daily in a diary by the participants. These falls as well as injuries and complications will be ascertained during monthly phone visits. The falls efficacy scale, BBS, cognition (MoCA), Mood (GDS-15), quality of life (SF12), instrumental activities of daily living (IADL), use of medical and non-medical services (FIMA) and adherence will be assessed at months 3, 6, and 12 and inner correspondence with practices (ICPH) at month 6. The trial is funded by the Federal Ministry of Education and Research (BMBF 01GL1805).

DISCUSSION

This study will determine whether EYT and Tai Chi reduce falls, injurious falls, fear of falling and healthcare utilisation and improve mobility, cognition, mood, quality of life and functional independence. A reduction of fall risk and fear of falling and an improvement of mobility, autonomy, quality of life, mood, and cognition are highly relevant for older people to cope with aging and diseases and to reduce healthcare costs.

Herbal Medicinal Product Use During Pregnancy and the Postnatal Period: A Systematic Review

Synthesis of pooled data on herbal medicinal products used during and after pregnancy highlights the need for robust safety studies.

OBJECTIVE:

To report the incidence and nature of herbal medicinal products' adverse events and herb–drug interactions used by some pregnant and postnatal women.

DATA SOURCES:

The Allied and Complementary Medicine Database, the Cumulative Index to Nursing and Allied Health Literature, EMBASE, the Cochrane Library, MEDLINE, Scopus, Web of Science, and ClinicalTrials.gov were searched from inception until August 2018.

METHODS OF STUDY SELECTION:

Any studies reporting adverse events, herb–drug interactions or absence thereof associated with herbal medicinal products used during pregnancy or the postnatal period were included. Conference abstracts, pilot studies, and nonhuman studies were excluded. All included studies were critically appraised by two independent reviewers.

TABULATION, INTEGRATION AND RESULTS:

Database searches retrieved 3,487 citations. After duplicate removal and review of titles, abstracts, and full-text, 115 articles were critically appraised. After excluding irrelevant and low-quality articles, 74 articles were included for data extraction and synthesis. Adverse drug reactions, congenital malformations, fetal growth retardation or herb–drug interactions were the primary study objective reported by 19 of the 74 included studies, 16 cohort studies, one cross-sectional survey, and two randomized controlled trials. A total of 47 herbal medicinal products and 1,067,071 women were included in this review. Use of almond oil was associated with preterm birth (odds ratio 2.09, 95% CI 1.07–4.08), oral raspberry leaf was associated with cesarean delivery (adjusted odds ratio [AOR] 3.47, 95% CI 1.45–8.28); heavy licorice use was associated with early preterm birth by 3.07-fold (95% CI 1.17–8.05). African herbal medicine mwanaphepo was associated with maternal morbidity (AOR 1.28; 95% CI 1.09–1.50), and neonatal death or morbidity. Fourteen studies reported absence of adverse events. Four studies reported herb–drug interactions, but none studied adverse events arising from them.

CONCLUSION:

The use of herbal medicinal products during pregnancy and the postnatal period should be discouraged until robust evidence of safety is available.

Attitudes Underlying Reliance on Complementary and Alternative Medicine

Objective: We aimed to map attitudes underlying complementary and alternative medicine (CAM) use, especially those involved in "dysfunctional CAM reliance," that is, forgoing biomedical treatment in a life-threatening situation in favor of alternative treatment. Analyses of modifiable determinants of CAM use were conducted at a sufficiently specific level to inform intervention development. Methods: We collected usable data on CAM-related attitudinal beliefs from 151 participants in Budapest with varying degrees of CAM use, which we analyzed using confidence interval-based estimation of relevance plots. Results: Although there were beliefs that the entire sample shared, there was a marked difference between the biomedical and CAM groups. These differences were beliefs concerning trust in various medical systems, the level of importance assigned to emotions in falling ill, and vitalism or Eastern concepts. Regarding CAM users in general, the most successful intervention targets are beliefs in vitalism on the one hand, and distrust in biomedicine on the other. In addressing dysfunctional CAM use specifically, the most significant beliefs pertain to "natural" cures and reliance on biomedical testing. Conclusions: Albeit much research has been carried out on the motivations behind CAM use, rarely do studies treat CAM users separately in order to scrutinize patterns of nonconventional medicine use and underlying cognition. This is the first study to begin pinpointing specific attitudes involved in dysfunctional CAM use to inform future intervention development. Such interventions would be essential for the prevention of incidents and mortality.

The importance of herbal medicine use in the German health-care system: prevalence, usage pattern, and influencing factors

Background

Prevalence rates for herbal medicine (HM) have been increasing worldwide. However, little is known about prevalence, user characteristics, usage pattern and factors influencing HM usage for the general German population.

Methods

A nationwide online survey on HM usage was conducted in Germany. The 2906 participants were categorised into three groups: the ones who used HM in the last 12 months, the ones who did not use HM in the last 12 months but in their lifetime, and the ones who did not use HM until now. Data were analysed by descriptive statistics, Chi Square tests and binary hierarchical logistic regression analyses.

Results

Prevalence rates of HM were found to be very high for the general German population. Self-medication appeared as a common praxis, when at the same time HM users responded that they do not inform their physician about it, rate their knowledge about HM as somewhat poor, and use the internet as the most frequent source of information. The HM user in the last 12 months was found to include people that were more likely female, highly educated, privately insured, employed, and engaged in a more health-oriented lifestyle. While certain sociodemographic- and health-related variables influence HM usage vs. non-usage, they explain variance only to a limited extent. For distinguishing the user in the last 12 months vs. the less recent user who did not use HM in the last 12 months, ratings on different reasons for HM usage were found to perform better as predictors than sociodemographic- and health-related variables.

Conclusions

This study demonstrated that HM usage plays an essential role in the German health-care system. Furthermore, the HM usage pattern may be potentially harmful for patients, as it included self-medication, little knowledge on interaction- and side-effects of HM, and a lack of communication with physicians about the usage. Moreover, prediction of HM usage in the previous year is impacted by variables beyond conventional sociodemographic- and health-related ones. In view of the high prevalence rates of HM in Germany, medical as well as health service providers should be aware of these issues.

The Impact of the Socio-Demographic Characteristics of Complementary and Alternative Medicine Users in Serbia on OTC Drug Consumption

The Aim of this research is to analyze how the socio-demographic characteristics of users of Complementary and Alternative Medicine (CAM) in Serbia influence and impact their consumption of OTC drugs. Respondents and methods: The study employed the third edition of the National Health Survey of the Republic of Serbia, published in 2013, as a data source covering the Serbian population. The sample comprised of 550 interviewed individuals who had been applying a variety of CAM treatments over the previous 12 months. Their socio-demographic characteristics were used as independent variables impacting the consumption of OTC drugs over the previous 2-week period, representing the dependent variable. Results: Two thirds (65.3%) of the CAM users consumed OTC drugs at their own discretion, without recommendation by a physician or a relevant prescription. Users of OTC drugs were most often females whose ages ranged within the average interval of 49.16 ± 16.02, whose education level was to secondary school diploma, who were married and employed, lived in urban areas, mostly Belgrade, belonged to the middle-income group, and followed relevant headlines via public information channels (TV, the internet, radio, and print). Comparison of the results revealed, on the one hand, that 2/3 of respondents who had used and 1/3 of those who did not consume OTC drugs had undergone fecal occult blood tests over the past year (p < 0.05) and, on the other hand, that those respondents had been less frequently hospitalized in the previous year (p = 0.05). In addition, the same responders were found to access available health care services more frequently than did others (p < 0.05). Conclusion: Since, according to the statistics, it is highly likely that respondents who were CAM- and OTC drug-users would be less frequently hospitalized and not use medical leave, these results provide a strong indication that this phenomenon should be investigated in more depth. Moreover, the areas to be considered when defining strategies for determining patient treatments should also include the influence of socio-demographic factors on the patient's consciousness that would enable easier understanding of the proper usage of OTC drugs.

Characteristics of complementary medicine therapists in Switzerland: A cross-sectional study

Objective

More than 27,000 complementary medicine (CM) therapists are registered in Switzerland, but limited data are available on their occupational profile and role in the healthcare system. Herein we aimed to gain a better understanding of the professional profile of non-physician licensed therapists, focusing on acupuncture, osteopathy, and European naturopathy.

Design

This cross-sectional study was based on an online anonymous survey conducted from March to June 2017.

Setting and participants

All 1549 non-physician registered osteopaths, acupuncturists, and naturopaths in the French-speaking part of Switzerland were asked to complete the survey.

Main outcome measures

We measured the therapists’ demographics, training and practice characteristics, and workload.

Results

A total of 426 therapists returned the questionnaire (response rate: 27.5%). The mean age of the respondents was 46.0 years (SD 11.6) and most were women (67.8%). CM represented the main professional activity for a majority of therapists (82.8%), most of whom were independent (86.3%). The length and number of consultations per month varied across professions. Multivariate analysis showed that acupuncturists and naturopaths performed significantly fewer consults per month than osteopaths did. However, consultation length was significantly longer for acupuncturists and naturopaths than for osteopaths. Acupuncturists (71.6%) and naturopaths (64.4%) were significantly more favorable than osteopaths (27.7%) to have consultation costs covered by basic health insurance. Professional profiles differed between osteopaths, on the one hand, and naturopaths and acupuncturists, on the other, mainly regarding workload, treatment duration, and main reasons to consult.

Conclusions

This first study to investigate a variety of therapist profiles in Switzerland provides useful information about their activities and role within the Swiss healthcare system. Although all three professions are encompassed under the same umbrella term (CM), our study showed that they have specific work cultures and areas of intervention in the healthcare system.

Patient Input in Regional Healthcare Planning-A Meaningful Contribution

Background: There are well-known methodological and analytical challenges in planning regional healthcare services (HCS). Increasingly, the need for data-derived planning, including user-perspectives, is discussed. This study aims to better understand the possible contribution of citizen experience in the assessment of regional HCS needs in two regions of Germany. Methods: We conducted a written survey in two regions of differing size-a community (3653 inhabitants) and a county (165,211 inhabitants). Multinomial logistic regression was used to assess the impact of sociodemographic and regional factors on the assessment of HCS provided by general practitioners (GPs) and specialists. Results: Except for age and financial resources available for one's own health, populations did not differ significantly between the regions. However, citizens' perception of HCS (measured by satisfaction with 1 = very good to 5 = very poor) differed clearly between different services (e.g., specialists: 3.8-4.3 and pharmacies: 1.7-2.5) as well as between regions (GPs: 1.7-3.1; therapists: 2.9-4). In the multivariate model, region (next to income and age) was a consistent predictor of the perception of GP- and specialist-provided care. Discussion: Citizens' perceptions of HCS correspond to regional provider density (the greater the density, the better the perception) and add insights into citizens' needs. Therefore, they can provide valuable information on regional HCS strengths and weaknesses and are a valid resource to support decision makers in shaping regional care structures.

Parent use of complementary medicine remedies and services for the management of respiratory tract infection in children: a qualitative study

BACKGROUND

The use of complementary and alternative medicine (CAM) is increasing globally, in both adults and children. A common condition where CAM is used in children is acute respiratory tract infection (ARTI). However, limited information exists regarding specific CAM modalities used in children, and the factors that influence a parent's decision to use CAM for ARTI in children. This research aimed to address this knowledge gap.

METHOD

This research used a qualitative descriptive approach. Parents residing in Greater Melbourne, Australia, who had children aged from 0-12 years, and had used CAM for treating ARTI in their children in the last 12 months, were eligible to participate. Parents' perspectives were captured using individual semi-structured interviews, which were then transcribed verbatim. Data were analysed using content analysis.

RESULTS

Twenty-four families were interviewed. Several strategies to improve trustworthiness were implemented. Three themes underpinning the parents' decision to use CAM emerged from the data: safety, internal drivers and external drivers. Parents used a breadth of different treatments, predominantly food as medicine, followed by aromatherapy and other CAM remedies typically found in the kitchen, to manage ARTI in their children. Parents often used both CAM practitioners and mainstream medicine to manage ARTI in their children. While mainstream medicine was typically used to rule out any sinister pathology, CAM was often used as a frontline treatment option, with food as medicine (e.g. soups) dominating. This was due in part to concerns regarding the negative aspects of pharmaceutical use. Parents utilised a diverse range of information sources to inform their decision-making, including friends, families and the internet; traditional sources of research evidence were generally not used.

CONCLUSION

Child safety was a major factor influencing a primary carer's decision to utilise CAM for ARTI. The safety and effectiveness of remedies utilised by parents now warrants further investigation.

The impact of uncertainty in society on the use of traditional, complementary and alternative medicine: a comparative study on visits to alternative/traditional/folk health care practitioners

Background

While traditional, complementary and alternative medicine (TCAM) is gaining increased interest worldwide, the structural factors associated with the usage of TCAM at the social level have not been sufficiently explored. We aim to understand the social structure of uncertainty in society that affects the TCAM usage for men and women.

Methods

We studied 32 countries using data from the International Social Survey Programme and the World Bank. In this study, we defined TCAM usage as visits to an alternative/traditional/folk health care practitioner during the past 12 months. We performed a correlation analysis and used a generalized linear model .

Results

The prevalence of TCAM usage in terms of visits to practitioners was 26.1% globally, while usage varied across the 32 countries. Generalized linear models showed that unemployment rate was associated with the prevalence of TCAM usage in terms of visits to practitioners.

Conclusions

At the social-structural level TCAM usage involving visits to practitioners was related to job insecurity. Job insecurity led to a decrease in TCAM usage regarding visits to practitioners. These findings suggest that it is necessary to consider the social-structural factors of uncertainty in society when designing health policies related to TCAM.

What motivates new, established and long-term users of herbal medicine: is there more than push and pull?

BACKGROUND

The use of herbal medicine (HM) has become an essential form of treatment and it is more and more common around the world. Little is known about the reasons that drive people to initially use HM or to maintain their behaviour, and whether the so-called "push and pull factors" known in the context of decision making for complementary and alternative medicine, also play a role for HM use. Here, our goal was to provide answers to these open questions and to analyse the reasons that motivate new, established and long-term HM consumers in detail.

METHODS

Thirteen reasons for HM usage, which were previously identified within a qualitative approach, were analysed quantitatively in a nationwide online survey in Germany. Data of 2,192 German HM users from the general population were grouped into new, established and long-term users. We performed a factor analysis in order to identify factors underlying the set of reasons.

RESULTS

We discovered a reliable factor associated with longstanding family traditions and cultural importance of HM in Germany. This finding shows that the reasons for HM use require a three-factor structure going beyond the well-known push and pull factors that explain the use of complementary and alternative medicine. In using the identified factors for further calculations, we were able to reveal important group differences and test how the factor scores perform as predictors for the new, established and long-term choice of HM. Our results showed that a high score on the push factor is associated more with initial HM usage, while long-term HM usage is impacted more by high scores on the pull and traditional factors.

CONCLUSIONS

Our exploratory survey and analysis of the reasons that underlie HM usage aimed at providing a better understanding of the decision for this treatment form. The findings of our work deliver insights for medical practitioners and health-care providers, including the role of family traditions for HM usage and the finding that new HM users are driven to use this treatment form in part because of negative aspects they associate with conventional medicine.

Acute and repeated toxicological study of Myelophil, an ethanol extract of a mixture of Astragali Radix and Salviae Miltiorrhizae Radix, in beagle dogs

BACKGROUND

To evaluate the pharmaceutical safety of Myelophil, an ethanol extract of a mixture of Astragali Radix and Salviae Miltiorrhizae Radix, using both acute and repeated toxicological studies.

METHODS

A total of 40 beagle dogs (20 each male and female) were fed doses up to 5,000 mg/kg for the acute study and up to 1,250 mg/kg for the 13-week repeated dose toxicological study. Adverse effects were examined intensively by comparing the differences between normal and drug-administered groups using clinical signs, autopsies, histopathological findings, hematology, urinalysis, and biochemical analysis.

RESULTS

No mortality or drug-related clinical signs were observed in the Myelophil-treated groups, except for vomiting due to an excessive dose (5,000 mg/kg). Likewise, in the repeated toxicity test, compound-colored stools in the Myelophil-treated groups and soft stools in all groups, including the control, were observed. No drug-related abnormalities were found in the histopathology, hematology, urinalysis, and biochemical analyses for any doses of Myelophil.

CONCLUSION

These results support the safety of Myelophil with a no observed adverse effect level (NOAEL) of 1250 mg/kg in beagle dogs, which corresponds to a human equivalent dose (HED) of 694 g/kg.

No Free Lunch With Herbal Preparations: Lessons From a Case of Parkinsonism and Depression Due to Herbal Medicine Containing Reserpine

The increasing use of herbal medicines calls for a heightened awareness of their potential side-effects. This especially pertains to western countries, where patients tend to use herbal medicine as self-medication, often alongside regular prescriptions, and physicians have less experience with their application. Here we report a case in which Parkinsonism, depression, and an atypical finding detected by dopamine transporter single-photon emission computed tomography were all belatedly recognized as side-effects of herbal medicine. This only occurred because one of its active ingredients, reserpine, has been extensively studied. For most other herbal medicines, however, knowledge about side-effects remains scarce or unavailable. Therefore, we suggest that physicians, when taking a medication history, should actively ask for the use of any herbal preparations.

Differences in healthcare utilisation between users and non-users of homeopathic products in Spain: Results from three waves of the National Health Survey (2011-2017)

OBJECTIVE

To compare the differences in the use of healthcare services: visits to the doctor and hospitalisation, performance of routine tests, and preventive influenza vaccination, between users and non-users of homeopathic products.

METHODS

We used the microdata for adults over 15 years old from three waves of the Spanish National Health Survey, corresponding to the years 2011, 2014 and 2017. We proposed a comparative design of a quasi-experimental type, considering as the treatment group the respondents who said that they had used homeopathic products in the past two weeks; and another group, for control, comprising respondents who said that they had not used this type of products, but only conventional medicines, with observable characteristics similar to those of the treatment group. We used a model for rare events logistics regression (relogit) to estimate the probability of using homeopathy. From the propensity score and a vector of control variables, we used techniques of genetic matching to match individuals from the treatment group with similar individuals belonging to the control group.

RESULTS

There are no statistically significant differences between users and non-users of homeopathy in visits to the general practitioner (P>|z| 0.387), to the specialist (P>|z| 0.52), in hospitalisations (P>|z| 0.592) or in the use of emergency services (P>|z| 0.109). Nor were there any statistically significant differences in the performance of routine tests, except for the faecal occult blood test, which is more prevalent in users of homeopathic products. 20.9% of users of homeopathy had done this test compared with 15.3% of non-users (P>|z| 0.022). There are also significant differences in vaccination against influenza with 12.6% of homeopathy users stating that they had been vaccinated in the last influenza campaign, against 21.0% of non-users (P>|z| <0.001). The health conditions which homeopathy users reported were constipation (OR: 1.65 CI: 1.16-2.36), malignant tumour (OR: 1.60 CI: 1.09-2.36) osteoporosis (OR: 1.49 CI: 1.05-2.10), varicose veins (OR: 1.35 CI: 1.05-1.74) and allergy (OR: 1.35 CI: 1.06-1.72).

CONCLUSIONS

Differences in the use of healthcare resources between users and non-users of homeopathic products have not been found to be statistically significant in Spain. It has been shown that most homeopathic products are used as a complement to treatment with conventional medicine. Nevertheless, our results highlight some warning signs which should raise the attention of healthcare authorities. The use of these therapies in patients with malignant tumours and the rejection of vaccines are warning signs of a possible health hazard in the long term.

"Then I went to a hospital abroad": acknowledging implications of stakeholders' differing risk understandings related to use of complementary and alternative medicine in European health care contexts

Background

Complementary and alternative medicine (CAM) is a rather novel issue within public healthcare and health policy-making. CAM use in Europe is widespread, patient-initiated, and patient-evaluated, and the regulation across countries has been evaluated as disharmonized. CAM users are left in an uncertain position, and patient safety may be threatened. How “risk” is understood by individuals in health policy-making and clinical encounters involving the use of CAM has not yet been much debated. The aim of this article is to explore and discuss the existence and possible consequences of differing risk understandings among stakeholders maneuvering in the complex landscape of CAM practice and CAM regulation contextualized by European public healthcare systems.

Methods

Qualitative data were derived from two studies on CAM in European healthcare contexts. Findings from the EU project CAMbrella on legislation and regulation of CAM were mixed with data from an interview study exploring risk understandings, communication, and decision-making among Scandinavian CAM users and their doctors. In a secondary content analysis, we constructed the case Sara as a typology to demonstrate important findings with regard to risk understandings and patient safety involving European citizens’ use of CAM in differing contexts.

Results

By combining and comparing individual and structural perspectives on risk and CAM use, we revealed underexplored gaps in risk understandings among individuals involved in European CAM regulation and legislation, and between CAM users and their medical doctors. This may cause health risks and uncertainties associated with CAM use and regulation. It may also negatively influence doctor-CAM user communication and CAM users’ trust in and use of public healthcare.

Conclusion

Acknowledging implications of stakeholders’ differing risk understandings related to CAM use and regulation may positively influence patient safety in European healthcare. Definitions of the concept of risk should include the factors uncertainty and subjectivity to grasp the full picture of possible risks associated with the use of CAM. To transform the findings of this study into practical settings, we introduce sets of questions relevant to operationalize the important question “What is risk?” in health policy-making, clinical encounters and risk research involving European patients’ use of CAM.

Use and acceptance of complementary and alternative medicine among medical students: a cross sectional study from Palestine

BACKGROUND

Teaching Complementary and alternative medicine (CAM) in medical schools is becoming prevalent worldwide. Few studies have been conducted to evaluate medical students' knowledge and attitude toward CAM. Therefore, this study was designed to assess CAM knowledge, attitudes, and beliefs among Palestinian medical students.

METHODS

This study was developed in a cross-sectional design. It targeted medical students at An-Najah National University, between January and April of 2018. We gathered the data from students using a questionnaire printed as a hard copy. Medical students of both sexes in their 4th, 5th, or 6th year of studies were included in the survey. The questionnaire consisted of 3 sections: demographic characteristics and detailed practices of the participants, their attitude and held beliefs towards CAM, and their knowledge on CAM. Mann-Whitney U Test and Kruskal-Wallis Test were used to test if there were differences between knowledge about CAM and the characteristics of the participants.

RESULTS

Of the 300 medical students who were offered the questionnaire, 251 students (43.8% male and 56.2% female) were included in the final analysis. Out of a maximum of 8 points, the mean knowledge score of the participants was 2.0 ± 1.6. The Kruskal-Wallis test showed a statistically significant difference in overall knowledge score among students of different year groups, with students at lower levels obtaining higher scores (P < 0.001). Additionally, the highest knowledge scores were found in students with low income, and students who came from the Palestinian refugee camps (P < 0.001). Students frequently recommended CAM modalities, with herbal medicine being the most recognized and used CAM modality and Ayurvedic medicine being the least recognized and recommended one. Social media was the most popular source of information about CAM, cited by 72.9% of the participants. Participants generally had a good attitude towards CAM but held varying beliefs about it.

CONCLUSIONS

In the current study, a knowledge gap regarding CAM was found among medical students in our sample, despite their good attitude towards the subject. Also, there was a general acceptance to include materials on CAM within the curriculum of medical students.

Complementary medicine use during cancer treatment and potential herb-drug interactions from a cross-sectional study in an academic centre

Complementary medicine (CM) is used by one third to one half of cancer patients throughout the world. The objective of this study was to describe the prevalence of CM use and the potential for interactions with cancer treatments in an academic oncology centre. A cross-sectional study was conducted among patients undergoing current cancer treatment. Among 132 included patients, 56% had used CM since their cancer diagnosis and 45% were using CM during cancer treatment at the time of the survey. The main CM used were green tea (35%), herbal tea (35%), homeopathy (27%), dietary supplements (27%), and herbal medicines (27%). A small majority of patients (58%) spontaneously mentioned the use of CM to their oncologist. Of 42 identified combinations of concomitant use of biologically based CM and anticancer agents among the study patients, the potential for pharmacokinetic interactions of clinical relevance was not expected in 17 combinations (40%), hypothetical and deemed unlikely in 23 (55%), and of probable low clinical relevance in 2 (5%). Considering the high prevalence of CM use, active enquiries should be made by healthcare professionals to detect symptoms that may relate to CM tolerance and effects or that suggest interactions between CM and cancer treatments.

Use of Complementary and Alternative Medicine in Japan: A Cross-sectional Internet Survey Using the Japanese Version of the International Complementary and Alternative Medicine Questionnaire

Introduction:

Although there have been several national survey studies on complementary and alternative medicine (CAM) use in Japan, previous studies have not been compared with investigations conducted in other countries. An international CAM questionnaire known as I-CAM-Q was developed through a two-day international workshop in 2006. The purpose of this study was to investigate the use of CAM by the general Japanese population using a modified version of the I-CAM-Q for the Japanese (I-CAM-QJ).

Methods:

We developed the I-CAM-QJ to conduct an internet survey of 3,208 participants from the general population of Japan in February 2016. The respondents included 1,592 males (49.6%), 1,348 university graduates (38.8%), 1,105 individuals in good health (34.4%), and 1,028 individuals with long-term illness or disability (32.0%).

Results:

Of the 3,208 respondents, 411 participants reported CAM use during the past 12 months (12.8%). The following therapies and products were used: Kampo medicines (over-the-counter Kampo medicines: 15.7%; prescribed Kampo medicines: 15.4%), dietary supplements 11.8%, massage services 3.9%, and physical therapy 3.5%. Regarding the use of self-care methods during the last 12 months, the following methods and products were used: bath salts 25.8% and walking 25.3%.

Conclusions:

An internet survey on CAM use by the general Japanese population with a modified I-CAM-Q (I-CAM-QJ) revealed that Kampo medicines and dietary supplements were the most commonly used CAMs in Japan.

Medicine is Patriarchal, But Alternative Medicine is Not the Answer

Women are over-represented within alternative medicine, both as consumers and as service providers. In this paper, I show that the appeal of alternative medicine to women relates to the neglect of women's health needs within scientific medicine. This is concerning because alternative medicine is severely limited in its therapeutic effects; therefore, those who choose alternative therapies are liable to experience inadequate healthcare. I argue that while many patients seek greater autonomy in alternative medicine, the absence of an evidence base and plausible mechanisms of action leaves patients unable to realize meaningful autonomy. This seems morally troubling, especially given that the neglect of women's needs within scientific medicine seems to contribute to preferences for alternative medicine. I conclude that the liberatory credentials of alternative medicine should be questioned and make recommendations to render scientific medicine better able to meet the needs of typical alternative medicine consumers.

The Use of Complementary and Alternative Medicine among Korean Young Adult Members of Fitness Centers

In general, the pattern and perception of complementary and alternative medicine (CAM) use in young people are little known. Particularly, given South Korea's dual health care system that includes both Korean traditional medicine and Western medicine, young adults in South Korea may be unique for the study of CAM use. Accordingly, this study investigated the modality, purpose, and perceptions of CAM use among young adults in South Korea and determined the predictors of CAM use. In addition, reasons for CAM use were compared to those for exercise. A survey was conducted among 649 young members of fitness centers (aged 20-39 years). The structured written questionnaire included the questions related to use of 30 CAM modalities, satisfaction with CAM use, factors associated with CAM use, reasons for exercise and CAM use, and perceptions of CAM. The most common therapies used in lifetime were acupuncture, massage, moxibustion/cupping, yoga, and diet-based therapies. The most satisfied therapy was massage followed by aroma therapy. The main reasons for using CAM were to relieve musculoskeletal pains while those for doing exercise were to lose weight, to promote health, and to have a positive body image. Multiple logistic regression analysis revealed that higher education level, having a religion, and having a health problem were significant independent predictors of CAM use after controlling for other factors. The majority of respondents reported "relief of pain and symptoms" as the perceived effect of CAM and "lack of advertising" as the weakness of CAM. The majority of respondents got CAM information from mass media and Internet. In conclusion, CAM use is significantly associated with education level, religious status, and health status in Korean young adult members of fitness centers. The main purposes of utilizing CAM and performing exercise are different.

Complementary medicine use, views, and experiences: a national survey in England

Background

In 2005,12% of the English population visited a complementary and alternative medicine (CAM) practitioner.

Aim

To obtain up-to-date general population figures for practitioner-led CAM use in England, and to discover people's views and experiences regarding access.

Design & setting

A face-to-face questionnaire survey was commissioned. A nationally representative adult quota sample (aged ≥15 years) was used.

Method

Ten questions were included within Ipsos MORI’s weekly population-based survey. The questions explored 12-month practitioner-led CAM use, reasons for non-use, views on NHS-provided CAM, and willingness to pay.

Results

Of 4862 adults surveyed, 766 (16%) had seen a CAM practitioner. People most commonly visited CAM practitioners for manual therapies (massage, osteopathy, chiropractic) and acupuncture, as well as yoga, pilates, reflexology, and mindfulness or meditation. Women, people with higher socioeconomic status (SES) and those in south England were more likely to access CAM. Musculoskeletal conditions (mainly back pain) accounted for 68% of use, and mental health 12%. Most was through self-referral (70%) and self-financing. GPs (17%) or NHS professionals (4%) referred and/or recommended CAM to users. These CAM users were more often unemployed, with lower income and social grade, and receiving NHS-funded CAM. Responders were willing to pay varying amounts for CAM; 22% would not pay anything. Almost two in five responders felt NHS funding and GP referral and/or endorsement would increase their CAM use.

Conclusion

CAM use in England is common for musculoskeletal and mental health problems, but varies by sex, geography, and SES. It is mainly self-referred and self-financed; some is GP-endorsed and/or referred, especially for individuals of lower SES. Researchers, patients, and commissioners should collaborate to research the effectiveness and cost-effectiveness of CAM and consider its availability on the NHS.

Scoping review of systematic reviews of complementary medicine for musculoskeletal and mental health conditions

OBJECTIVE

To identify potentially effective complementary approaches for musculoskeletal (MSK)-mental health (MH) comorbidity, by synthesising evidence on effectiveness, cost-effectiveness and safety from systematic reviews (SRs).

DESIGN

Scoping review of SRs.

METHODS

We searched literature databases, registries and reference lists, and contacted key authors and professional organisations to identify SRs of randomised controlled trials for complementary medicine for MSK or MH. Inclusion criteria were: published after 2004, studying adults, in English and scoring >50% on Assessing the Methodological Quality of Systematic Reviews (AMSTAR); quality appraisal checklist). SRs were synthesised to identify research priorities, based on moderate/good quality evidence, sample size and indication of cost-effectiveness and safety.

RESULTS

We included 84 MSK SRs and 27 MH SRs. Only one focused on MSK-MH comorbidity. Meditative approaches and yoga may improve MH outcomes in MSK populations. Yoga and tai chi had moderate/good evidence for MSK and MH conditions. SRs reported moderate/good quality evidence (any comparator) in a moderate/large population for: low back pain (LBP) (yoga, acupuncture, spinal manipulation/mobilisation, osteopathy), osteoarthritis (OA) (acupuncture, tai chi), neck pain (acupuncture, manipulation/manual therapy), myofascial trigger point pain (acupuncture), depression (mindfulness-based stress reduction (MBSR), meditation, tai chi, relaxation), anxiety (meditation/MBSR, moving meditation, yoga), sleep disorders (meditative/mind-body movement) and stress/distress (mindfulness). The majority of these complementary approaches had some evidence of safety-only three had evidence of harm. There was some evidence of cost-effectiveness for spinal manipulation/mobilisation and acupuncture for LBP, and manual therapy/manipulation for neck pain, but few SRs reviewed cost-effectiveness and many found no data.

CONCLUSIONS

Only one SR studied MSK-MH comorbidity. Research priorities for complementary medicine for both MSK and MH (LBP, OA, depression, anxiety and sleep problems) are yoga, mindfulness and tai chi. Despite the large number of SRs and the prevalence of comorbidity, more high-quality, large randomised controlled trials in comorbid populations are needed.
