The supply of complementary and alternative medicine in Swiss hospitals

OBJECTIVES: Over the past few years, a considerable increase in complementary and alternative medicine (CAM) has been observed, particularly in primary care. In contrast little is known about the supply of CAM in Swiss hospitals. This study aims at the investigation of amount and structure of CAM activities of Swiss hospitals. MATERIALS AND METHODS: We designed a cross-sectional survey using a 2-step, questionnaire- based approach acquiring overview information form hospital managers in a first questionnaire leading to detailed information on CAM usage at medical department level (head of department). This second questionnaire provides data of physician-based and non-physician-based CAM supply. RESULTS: The size of hospitals was significantly associated with the provision of CAM. 33% of the hospital managers indicated 1 or more medical doctor (MD) using CAM in their hospital compared to 37% of confirmation on department level (Kappa value 0.5). Mostly different CAM methods were applied. Acupuncture was used most frequently. However only 13 hospitals (11%) occupied more than 3 CAM MDs and only 5 hospitals had more than 2 full-time equivalents for MDs. Furthermore, 74.7% of these personnel resources were dedicated for outpatient care. In terms of CAM methods anthroposophic medicine accounted for more than half of the total personnel costs. On the other hand usage of non-physician based CAM accounted for 41% according to hospital managers compared to 64% of CAM usage according to medical departments (Kappa values 0.31). Reflexology of the foot was used most frequently. CONCLUSION: Total supply of CAM in Swiss hospitals is low and concentrates on few hospitals. Acupuncture is the widest spread discipline but anthroposophic medicine spends the most resources. The study shows that a high patient demand for CAM faces low supply in hospitals.

Extent and structure of health insurance expenditures for complementary and alternative medicine in Swiss primary care

BACKGROUND: The study is part of a nationwide evaluation of complementary and alternative medicine (CAM) in primary care in Switzerland. The goal was to evaluate the extent and structure of basic health insurance expenditures for complementary and alternative medicine in Swiss primary care. METHODS: The study was designed as a cross-sectional evaluation of Swiss primary care providers and included 262 certified CAM physicians, 151 noncertified CAM physicians and 172 conventional physicians. The study was based on data from a mailed questionnaire and on reimbursement information obtained from health insurers. It was therefore purely observational, without interference into diagnostic and therapeutic procedures applied or prescribed by physicians. Main outcome measures included average reimbursed costs per patient, structured into consultation- and medication-related costs, and referred costs. RESULTS: Total average reimbursed cost per patient did not differ between CAM physicians and conventional practitioners, but considerable differences were observed in cost structure. The proportions of reimbursed costs for consultation time were 56% for certified CAM, 41% for noncertified CAM physicians and 40% for conventional physicians; medication costs--including expenditures for prescriptions and directly dispensed drugs--respectively accounted for 35%, 18%, and 51% of costs. CONCLUSION: The results indicate no significant difference for overall treatment cost per patient between CAM and COM primary care in Switzerland. However, CAM physicians treat lower numbers of patients and a more cost-favourable patient population than conventional physicians. Differences in cost structure reflect more patient-centred and individualized treatment modalities of CAM physicians.

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.

[Complementary and alternative medicine in primary care in Switzerland]

OBJECTIVE: This study investigated the current supply of complementary and alternative medicine (CAM) in Swiss primary care. Information was collected on physicians' qualifications in CAM, frequency of patients' demand for CAM, physicians' supply and temporal resources for CAM as well as physicians' referrals to CAM. MATERIAL AND METHODS: 750 (500 German-speaking and 250 French-speaking) randomly selected Swiss female and male primary care physicians were asked to complete a questionnaire (response rate 50.4%). Sociodemographic data on professional training, place of residence, and sex were used to calculate a weighting factor to correct the responders' data in the analysis accordingly. RESULTS: 14.2% of the physicians were qualified in at least one CAM discipline. Around 30% (95% confidence interval 25.4-34.6%) of the physicians were asked for CAM by their patients more than once a week. Homeopathy and phytotherapy were the most frequently offered therapies, followed by traditional Chinese medicine (TCM)/acupuncture. 62.5% (57.6-67.4%) of the physicians refer their patients to CAM. Most patients were referred to TCM/acupuncture. Of the 37.2% (32.6-42.4%) of the physicians who do not refer their patients to CAM, around 40% (35.1-44.9%) offer it themselves. CONCLUSION: About three quarters of the physicians offer CAM themselves or refer their patients to CAM treatments. CAM is very important in primary medical care in Switzerland. Clear regulations for CAM are required in order to ensure a high quality in care.

The Effect of the Japan 2011 Disaster on Nuclear and Alternative Energy Stocks Worldwide: An Event Study

This event study investigates the impact of the Japanese nuclear disaster in Fukushima-Daiichi on the daily stock prices of French, German, Japanese, and U.S. nuclear utility and alternative energy firms. Hypotheses regarding the (cumulative) abnormal returns based on a three-factor model are analyzed through joint tests by multivariate regression models and bootstrapping. Our results show significant abnormal returns for Japanese nuclear utility firms during the one-week event window and the subsequent four-week post-event window. Furthermore, while French and German nuclear utility and alternative energy stocks exhibit significant abnormal returns during the event window, we cannot confirm abnormal returns for U.S. stocks.

Male reproductive pattern in a polygynous ungulate with a slow life-history: the role of age, social status and alternative mating tactics

According to life-history theory age-dependent investments into reproduction are thought to co-vary with survival and growth of animals. In polygynous species, in which size is an important determinant of reproductive success, male reproduction via alternative mating tactics at young age are consequently expected to be the less frequent in species with higher survival. We tested this hypothesis in male Alpine ibex (Capra ibex), a highly sexually dimorphic mountain ungulate whose males have been reported to exhibit extremely high adult survival rates. Using data from two offspring cohorts in a population in the Swiss Alps, the effects of age, dominance and mating tactic on the likelihood of paternity were inferred within a Bayesian framework. In accordance with our hypothesis, reproductive success in male Alpine ibex was heavily biased towards older, dominant males that monopolized access to receptive females by adopting the 'tending' tactic, while success among young, subordinate males via the sneaking tactic 'coursing' was in general low and rare. In addition, we detected a high reproductive skew in male Alpine ibex, suggesting a large opportunity for selection. Compared with other ungulates with higher mortality rates, reproduction among young male Alpine ibex was much lower and more sporadic. Consistent with that, further examinations on the species level indicated that in polygynous ungulates the significance of early reproduction appears to decrease with increasing survival. Overall, this study supports the theory that survival prospects of males modulate the investments into reproduction via alternative mating tactics early in life. In the case of male Alpine ibex, the results indicate that their life-history strategy targets for long life, slow and prolonged growth and late reproduction.

Efficacy of quality criteria to identify potentially harmful information: a cross-sectional survey of complementary and alternative medicine web sites.

BACKGROUND: Many users search the Internet for answers to health questions. Complementary and alternative medicine (CAM) is a particularly common search topic. Because many CAM therapies do not require a clinician's prescription, false or misleading CAM information may be more dangerous than information about traditional therapies. Many quality criteria have been suggested to filter out potentially harmful online health information. However, assessing the accuracy of CAM information is uniquely challenging since CAM is generally not supported by conventional literature. OBJECTIVE: The purpose of this study is to determine whether domain-independent technical quality criteria can identify potentially harmful online CAM content. METHODS: We analyzed 150 Web sites retrieved from a search for the three most popular herbs: ginseng, ginkgo and St. John's wort and their purported uses on the ten most commonly used search engines. The presence of technical quality criteria as well as potentially harmful statements (commissions) and vital information that should have been mentioned (omissions) was recorded. RESULTS: Thirty-eight sites (25%) contained statements that could lead to direct physical harm if acted upon. One hundred forty five sites (97%) had omitted information. We found no relationship between technical quality criteria and potentially harmful information. CONCLUSIONS: Current technical quality criteria do not identify potentially harmful CAM information online. Consumers should be warned to use other means of validation or to trust only known sites. Quality criteria that consider the uniqueness of CAM must be developed and validated.

Evaluating the prevalence, content and readability of complementary and alternative medicine (CAM) web pages on the internet.

Complementary and alternative medicine (CAM) use is growing rapidly. As CAM is relatively unregulated, it is important to evaluate the type and availability of CAM information. The goal of this study is to deter-mine the prevalence, content and readability of online CAM information based on searches for arthritis, diabetes and fibromyalgia using four common search engines. Fifty-eight of 599 web pages retrieved by a "condition search" (9.6%) were CAM-oriented. Of 216 CAM pages found by the "condition" and "condition + herbs" searches, 78% were authored by commercial organizations, whose pur-pose involved commerce 69% of the time and 52.3% had no references. Although 98% of the CAM information was intended for consumers, the mean read-ability was at grade level 11. We conclude that consumers searching the web for health information are likely to encounter consumer-oriented CAM advertising, which is difficult to read and is not supported by the conventional literature.
