Complementary and alternative medicine costs - a systematic literature review

Objective: The aim of this literature review, performed within the framework of the Swiss governmental Program of Evaluation of Complementary Medicine (PEK), was to investigate costs of complementary and alternative medicine (CAM). Materials and Methods: A systematic literature search was conducted in 11 electronic databases. All retrieved titles and reference lists were also hand-searched. Results: 38 publications were found: 23 on CAM of various definitions (medical and non-medical practitioners, over-the-counter products), 13 on homeopathy, 2 on phytotherapy. Studies investigated different kinds of costs (direct or indirect) and used different methods (prospective or retrospective questionnaires, data analyses, cost-effectiveness models). Most studies report 'out of pocket' costs, because CAM is usually not covered by health insurance. Costs per CAM-treatment / patient / month were AUD 7-66, CAD 250 and GBP 13.62 +/- 1.61. Costs per treatment were EUR 205 (range: 15-1,278), USD 414 +/- 269 and USD 1,127. In two analyses phytotherapy proved to be cost-effective. One study revealed a reduction of 1.5 days of absenteeism from work in the CAM group compared to conventionally treated patients. Another study, performed by a health insurance company reported a slight increase in direct costs for CAM. Costs for CAM covered by insurance companies amounted to approximately 0.2-0.5% of the total healthcare budget (Switzerland, 2003). Publications had several limitations, e.g. efficacy of therapies was rarely reported. As compared to conventional patients, CAM patients tend to cause lower costs. Conclusion: Results suggest lower costs for CAM than for conventional patients, but the limited methodological quality lowers the significance of the available data. Further well-designed studies and models are required.

[Medicine of yore in the Moesano]

Through a series of walks with former colleagues and investigations in archives the author succeeded in reconstructing the medical past of the Moesano, a remote region of the italian speaking Grisons comprising the valleys of Calanca and Mesolcina. His analysis illustrates and reviews the demographic movements in a district of which certain parts are on the way of depopulation, the medical practitioners who followed one another during the last century, their daily activities under circumstances totally different from ours, the means at their disposal in particular the therapeutical possibilities an overview of the popular medicines of that time and a short historical report about the health resort of San Bernardino.

Twenty-three per cent of the Swiss adult population are using complementary medicine

Aim of the study: This study investigated the use among the Swiss adult population and the regional dissemination in Switzerland of various methods of complementary medicine (CM). It focused on CM methods that required visiting a physician or therapist and excluded e.g. over-the-counter drugs. Data and Methods: Data of the Swiss Health Survey 2007 were obtained from the Swiss Federal Statistical Office. This survey is performed every 5 years in a sample and is representative of the Swiss resident population from the age of 15 on. It consists of a telephone interview followed by a written questionnaire (2007: 18'760 and 14'432 respondents, respectively) and includes questions about people's state of health, general living conditions, lifestyle, health insurance and usage of health services. Users and non-users of CM were compared using logistic regression models. Results: 23.0 % of the Swiss adult population (women: 30.5 %, men: 15.2 %) used CM during the 12 months before the survey. Homeopathy (6.4 %), osteopathy (5.4 %) and acupuncture (4.9 %) were the most popular methods. The average number of treatments within 12 months for these three methods was 3.1 ± 3.6, 3.5 ± 3.3 and 6.6 ± 5.8, respectively. For treatments with homeopathy and acupuncture, medical practitioners were more commonly consulted than non-medical practitioners, for treatments with osteopathy no difference was found. By means of logistic regression, CM users and non-users were compared. There were significant differences in the use of CM between genders, age groups, levels of education and areas of living. Women, people aged 25 to 64 years, and people with higher levels of education used CM more commonly than men, people below 25 or above 64 years of age, or those with poorer education. Lake Geneva region and central Switzerland had a higher proportion of CM users than the other regions. Discussion: Almost one fourth of the Swiss adult population had used CM within 12 months before the survey. User profiles were comparable to those in other countries. Despite a generally lower self-perceived health status, elderly people were less likely to use CM. Reference: Klein SD, Frei-Erb M, Wolf U. Usage of complementary medicine across Switzerland.

Twenty-three per cent of the Swiss adult population are using complementary medicine

Aim of the study Various forms of complementary medicine (CM) play an important role in the Swiss health care system, they are appreciated by a majority of the population and mostly used complementarily rather than alternatively to conventional medicine. This study investigates, how many people in Switzerland are actually being treated with CM, and what the most popular methods of CM are. Data Data of the Swiss Health Survey 2007 were obtained from the Swiss Federal Statistical Office. This survey is performed every 5 years amongst a sample of the Swiss resident population above 15 years of age. It consists of a telephone interview followed by a written questionnaire (2007: 18'760 and 14'432 respondents, respectively) and includes questions about people's state of health, general living conditions, lifestyle, health insurance and usage of health services. Results 23.0% of the Swiss adult population (women: 30.5%, men: 15.2%) used CM during the 12 months before the survey. Homeopathy (6.4%), osteopathy (5.4%) and acupuncture (4.9%) were the most popular methods. The average number of treatments within 12 months for these three methods was 3.1, 3.5 and 6.6, respectively. For treatments with homeopathy and acupuncture, medical practitioners were more commonly consulted than non-medical practitioners, for treatments with osteopathy no difference was found. By means of logistic regression, CM users and non-users were compared. There were significant differences in the use of CM between genders, age groups, levels of education and areas of living. Women, people aged 25 to 64 years, and people with higher education used CM more commonly than men, people below 25 or above 64 years of age, or those with poorer education. Lake Geneva region and central Switzerland had a higher proportion of CM users than the other regions. Discussion While 2 years ago, 67.0% of the Swiss population approved a referendum in favour of CM, we find that 23.0% are in fact using it. Current political discussions focus on effectiveness, cost effectiveness and suitability of CM to decide which methods should be permanently covered by the basic health insurance.

Physicians' knowledge and continuing medical education regarding fitness to drive: a questionnaire-based survey in Southeast Switzerland

Valid information for physicians in Switzerland concerning knowledge and continuing education in traffic medicine is not available. Also, their attitude to the legally prescribed periodic driving fitness examinations is unclear. In order to gain more information about these topics, 635 resident physicians in Southeast Switzerland were sent a questionnaire (response rate 52%). In a self-estimation, 79% of the queried physicians claimed to know the minimal medical requirements for drivers which are important in their specialty. Statistically significant differences existed between the specialties, whereby general practitioners most frequently claimed to know the minimal medical requirements (90%). It appears that the minimal medical requirements for drivers are well known to the queried physicians. Fifty-two percent of the physicians favored an expansion of continuing education in traffic medicine. Such an expansion was desired to a lesser extent by physicians without knowledge of the minimal requirements (p < 0.001). A clear majority of the medical professionals adjudged the legally prescribed periodic driving fitness examinations as being an expedient means to identify unfit drivers. A national standardized form for reporting potentially unfit drivers to the licensing authorities was supported by 68% of the responding physicians. Such a form could simplify and standardize the reports to the licensing authorities.

[Periprosthetic joint infections - a review for general practitioners]

The number of prosthetic joint implantation is continuously increasing. Periprosthetic joint infection is a rare but serious complication. The correct diagnosis is essential for successful treatment. It requires the close collaboration between general practitioners, orthopaedic surgeons and infectious disease specialists. A delayed diagnosis sets hurdles to the medical and surgical treatment. Also, antimicrobial treatment without proper microbiological sampling must be avoided. Swabs from wounds are not helpful, because the results represent the skin flora, but not the causative pathogen of infection. The general practitioner is the first physician that patients contact and has, therefore, a central role in diagnosing and managing periprosthetic joint infections. In this review, classification, diagnostic means and treatment concepts of periprosthetic joint infections are presented.

Complementary and conventional medicine in Switzerland: comparing characteristics of general practitioners

OBJECTIVES: Do structural characteristics of general practitioners (GPs) who practice complementary medicine (CAM) differ from those GPs who do not? Assessed characteristics included experience and professional integration of general practitioners (GPs), workload, medical activities, and personal and technical resources of practices. The investigated CAM disciplines were anthroposophic medicine, homoeopathy, traditional Chinese medicine, neural therapy and herbal medicine. MATERIAL AND METHODS: We designed a cross-sectional study with convenience and stratified samples of GPs providing conventional (COM) and/or complementary primary care in Switzerland. The samples were taken from the database of the Swiss medical association (FMH) and from CAM societies. Data were collected using a postal questionnaire. RESULTS: Of the 650 practitioners who were included in the study, 191 were COM, 167 noncertified CAM and 292 certified CAM physicians. The proportion of females was higher in the population of CAM physicians. Gender-adjusted age did not differ between CAM and COM physicians. Nearly twice as many CAM physicians work part-time. Differences were also seen for the majority of structural characteristics such as qualification of physicians, type of practice, type of staff, and presence of technical equipment. CONCLUSION: The study results show that structural characteristics of primary health care do differ between CAM and COM practitioners. We assumed that the activities of GPs are defined essentially by analyzed structures. The results are to be considered for evaluations in primary health care, particularly when quality of health care is assessed.

Systematic counselling by general practitioners for promoting physical activity in elderly patients: a feasibility study

RESEARCH QUESTIONS: To investigate how the daily physical activities of elderly patients can be enhanced by systematic counselling conducted by general practitioners (GPs). METHODS: In this feasibility study with pre-post design, 29 people (14 females, mean age 72.2 years, SD = 6.1) were enrolled during routine visits by two general practitioners. A baseline assessment of current physical activity based on the stages according to the Transtheoretical Model was followed by a counselling session. The target behaviour was defined by performance of 30 minutes of daily moderate-intensity activities that increase the breathing rate, on five days per week. At the 2-month follow-up, subjects were assessed for improvement in stage of physical activity since baseline. After the end of the intervention, participating GPs and patients were asked questions focusing on the feasibility, acceptance and usefulness of counselling. RESULTS: Interview results showed that the two GPs considered the counselling protocol easy to handle and useful for promoting physical activity. Counselling sessions were especially encouraging for the not sufficiently active people. Most of them would like to have additional counselling session. At baseline, 9 of 29 people were sufficiently active. After 2 months, this proportion was 21 of 29. The mean of the number of minutes of physical activity during the previous 4 weeks increased from 247 to 436 minutes (weekly). CONCLUSIONS: The programme was judged positively by the general practitioners and the participating elderly patients. Systematic counselling by general practitioners led to an increase in the physical activity behaviour. Therefore, a more rigorous randomised controlled trial with adequate followup is recommended.

Competencies in arts therapies: A rating of importance, training and performance by practitioners and referring professionals in Switzerland

This survey was conducted in developing a final specialized examination for all arts therapists in Switzerland by the Council of Swiss Arts Therapy Associations (CSATA). Forty-eight generic key competencies (GKC) were sent to all 1235 arts therapists in five different disciplines in Switzerland (response 47.5%) and to 384 referring professionals and employers (RPE) listed by therapists (response 42%). The mean importance of GKC was rated high (4 points of 5) by practitioners and RPE. Different opinions on importance of GKC in disciplines included artistic ability and psychotherapeutic relative to medical orientation. The training of competencies was rated lower by practitioners (3.48 points) and different in the eight competence categories and five disciplines. Areas of weak training were identified. The performance of GKC was rated by referring professionals equally to its importance (mean +0.3 points) and showed a good understanding of competencies by RPE. Judging of performance was difficult for RPE in more than 20% of items. The results provide criteria for detailed outcome assessments and the advancement of a final examination for arts therapists in Switzerland.

How Comprehensible, Interesting and Relevant is Current Research in Traditional Chinese Medicine for Practitioners?

Purpose: In traditional Chinese medicine (TCM) as in other fields of complementary medicine, research does not necessarily follow the sequence from in vitro studies via phase I to phase IV clinical trials, but all steps are being investigated simultaneously. Here, we aimed to investigate which kinds of studies were interesting and relevant for practitioners. Methods: Thirty abstracts from articles on TCM published between April and June 2012 were randomly chosen, including 5 abstracts each of in vitro studies, animal studies, case reports or series, studies with healthy volunteers, trials with patients, or reviews and meta-analyses. Six TCM practitioners (2 female, 5 non-medical, average age 46 years, average practical TCM experience 9 years) rated 10 abstracts each on a 5 point Likert scale (1=very poor to 5=very good) regarding comprehensibility, interest, relevance to practice, information for patients, and promoting reputation of TCM. Average ratings for each group of abstracts were calculated. Results: Comprehensibility of the abstracts was generally rated as good. Case reports/series, studies in healthy volunteers and trials with patients were rated interesting by the practitioners (average rating = 3.7, 3.8 and 3.7, respectively). Relevance to practice was mediocre for all types (2.5 to 3.5). In vitro studies and reviews/meta-analyses were not rated useful as information for patients (2.0). Reviews/Meta-analyses were considered negative for the reputation of TCM (2.2). Conclusions: Practitioners of TCM find abstracts of study results generally comprehensible and interesting. Case reports/series were rated in a similar way as trials with patients. Although TCM is commonly taught by means of case reports, practitioners seemed to value clinical trials. Abstracts of reviews/meta-analyses were rated rather uninformative, which was possibly due to several inconclusive results and the lack of detailed information in these abstracts.

Relationship between depressive symptoms and acute low back pain at first medical consultation, three and six weeks of primary care

Background: Aim of the study was to test lagged reciprocal effects of depressive symptoms and acute low back pain (LBP) across the first weeks of primary care. Methods: In a prospective inception cohort study, 221 primary care patients with acute or subacute LBP were assessed at the time of initial consultation and then followed up at three and six weeks. Key measures were depressive symptoms (modified Zung Self-Rating Depression Scale) and LBP (sensory pain, present pain index and visual analogue scale of the Short-Form McGill Pain Questionnaire). Results: When only cross-lagged effects of six weeks were tested, a reciprocal positive relationship between LBP and depressive symptoms was shown in a cross-lagged structural equation model (β = .15 and .17, p < .01). When lagged reciprocal paths at three- and six-week follow-up were tested, depressive symptoms at the time of consultation predicted higher LBP severity after three weeks (β = .23, p < .01). LBP after three weeks had in turn a positive cross-lagged effect on depression after six weeks (β = .27, p < .001). Conclusions: Reciprocal effects of depressive symptoms and LBP seem to depend on time under medical treatment. Health practitioners should screen for and treat depressive symptoms at the first consultation to improve the LBP treatment.

General Practitioners' vitamin K antagonist monitoring is associated with better blood pressure control in patients with hypertension - a cross-sectional database study.

BACKGROUND Patients requiring anticoagulation suffer from comorbidities such as hypertension. On the occasion of INR monitoring, general practitioners (GPs) have the opportunity to control for blood pressure (BP). We aimed to evaluate the impact of Vitamin-K Antagonist (VKA) monitoring by GPs on BP control in patients with hypertension. METHODS We cross-sectionally analyzed the database of the Swiss Family Medicine ICPC Research using Electronic Medical Records (FIRE) of 60 general practices in a primary care setting in Switzerland. This database includes 113,335 patients who visited their GP between 2009 and 2013. We identified patients with hypertension based on antihypertensive medication prescribed for ≥6 months. We compared patients with VKA for ≥3 months and patients without such treatment regarding BP control. We adjusted for age, sex, observation period, number of consultations and comorbidity. RESULTS We identified 4,412 patients with hypertension and blood pressure recordings in the FIRE database. Among these, 569 (12.9 %) were on Phenprocoumon (VKA) and 3,843 (87.1 %) had no anticoagulation. Mean systolic and diastolic BP was significantly lower in the VKA group (130.6 ± 14.9 vs 139.8 ± 15.8 and 76.6 ± 7.9 vs 81.3 ± 9.3 mm Hg) (p < 0.001 for both). The difference remained after adjusting for possible confounders. Systolic and diastolic BP were significantly lower in the VKA group, reaching a mean difference of -8.4 mm Hg (95 % CI -9.8 to -7.0 mm Hg) and -1.5 mm Hg (95 % CI -2.3 to -0.7 mm Hg), respectively (p < 0.001 for both). CONCLUSIONS In a large sample of hypertensive patients in Switzerland, VKA treatment was independently associated with better systolic and diastolic BP control. The observed effect could be due to better compliance with antihypertensive medication in patients treated with VKA. Therefore, we conclude to be aware of this possible benefit especially in patients with lower expected compliance and with multimorbidity.

Variation in treatment strategies of Swiss general practitioners for subclinical hypothyroidism in older adults.

QUESTIONS UNDER STUDY As the best management of subclinical hypothyroidism is controversial, we aimed to assess variations in treatment strategies depending on different Swiss regions, physician and patient characteristics. METHODS We performed a case-based survey among general practitioners (GPs) in different Swiss regions, which consisted of eight hypothetical cases presenting a female patient with subclinical hypothyroidism and nonspecific complaints differing by age, vitality status and thyroid-stimulating hormone (TSH) concentration. RESULTS A total of 262 GPs participated in the survey. There was considerable variation in the levothyroxine starting dose chosen by GPs, ranging from 25 µg to 100 µg. Across the Swiss regions, GPs in the Bern region were significantly more inclined to treat, with a higher probability of initiating treatment (60%, p = 0.01) and higher mean starting doses (45 µg, p <0.01) compared with the French-speaking region (44%, 36 µg); the Zurich region had intermediate values (52%, 39 µg). We found no association between treatment rate and other physician characteristics. GPs were more reluctant to initiate treatment in 85-year-old than in 70-year-old women (odds ratio [OR] 0.77, 95% confidence interval [CI] 0.63-0.94), and more likely to treat women with a TSH of 15 mU/l than those with a TSH of 6mU/l (OR 8.71, 95% CI 6.21-12.20). CONCLUSIONS There are strong variations in treatment strategies for elderly patients with subclinical hypothyroidism across different Swiss regions, including use of higher starting doses than the recommended 25 µg in the Swiss guidelines, which recommend a starting dose of 25 µg. These variations likely reflect the current uncertainty about the benefits of treatment, which arise from the current lack of evidence from adequately powered clinical trials.
