Health status and health care utilisation of patients in complementary and conventional primary care in Switzerland--an observational study

BACKGROUND: The study is part of a nationwide evaluation of complementary and alternative medicine (CAM) in primary care in Switzerland. OBJECTIVES: Patient health status with respect to demographic attributes such as gender, age, and health care utilisation pattern was studied and compared with conventional primary care. METHODS: The study was performed as a cross-sectional survey including 11932 adult patients seeking complementary or conventional primary care. Patients were asked to document their self-perceived health status by completing a questionnaire in the waiting room. Physicians were performing conventional medicine and/or various forms of complementary primary care such as homeopathy, anthroposophic medicine, neural therapy, herbal medicine, or traditional Chinese medicine. Additional information on patient demographics and yearly consultation rates for participating physicians was obtained from the data pool of all Swiss health insurers. These data were used to confirm the survey results. RESULTS: We observed considerable and significant differences in demographic attributes of patients seeking complementary and conventional care. Patients seeking complementary care documented longer lasting and more severe main health problems than patients in conventional care. The number of previous physician visits differed between patient groups, which indicates higher consumption of medical resources by CAM patients. CONCLUSIONS: The study supports the hypothesis of differences in socio-demographic and behavioural attributes of patients seeking conventional medicine or CAM in primary care. The study provides empirical evidence that CAM users are requiring more physician-based medical services in primary care than users of conventional medicine.

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.

Palliative in-patient cancer treatment in an anthroposophic hospital: I. Treatment patterns and compliance with anthroposophic medicine

BACKGROUND: Complementary and alternative medicine (CAM) and most of all anthroposophic medicine (AM) are important features of cancer treatment in Switzerland. While the number of epidemiological investigations into the use of such therapies is increasing, there is a distinct lack of reports regarding the combination of conventional and CAM methods. PATIENTS AND METHODS: 144 in-patients with advanced epithelial cancers were enrolled in a prospective quality-of-life (QoL) study at the Lukas Klinik (LK), Arlesheim, Switzerland. Tumor-related treatment was assessed 4 months prior to admission, during hospitalization and 4 months after baseline. OBJECTIVE: We aimed at giving a detailed account of conventional, AM and CAM treatment patterns in palliative care, before, during and after hospitalization, with emphasis on compliance with AM after discharge. RESULTS: Certain conventional treatments featured less during hospitalization than before but were resumed after discharge (chemotherapy, radiotherapy, sleeping pills, psychoactive drugs). Hormone therapy, corticosteroids, analgesics WHO III and antidepressants remained constant. AM treatment consisted of Iscador? (mistletoe), other plant- or mineral-derived medication, baths, massage, eurythmy, art therapy, counseling and lactovegetarian diet. Compliance after discharge was highest with Iscador (90%) and lowest with art therapy (14%). Many patients remained in the care of AM physicians. Other CAM and psychological methods were initially used by 39.9% of patients. After 4 months, the use had decreased with few exceptions. CONCLUSION: During holistic palliative treatment in an anthroposophic hospital, certain conventional treatments featured less whereas others remained constant. After discharge, chemotherapy returned to previous levels, AM compliance remained high, the use of other CAM therapies low.

Antisense-mediated melanoma inhibitor of apoptosis protein downregulation sensitizes G361 melanoma cells to cisplatin

Malignant melanoma is an aggressive form of skin cancer that is highly resistant to conventional therapies. The melanoma inhibitor of apoptosis protein is a potent inhibitor of apoptosis and is overexpressed in melanoma cells, but undetectable in most normal tissues including melanocytes. We designed 20-mer phosphorothioate antisense oligonucleotides complementary to five putatively single-stranded sites on the melanoma inhibitor of apoptosis protein mRNA and investigated their ability to sensitize G361 melanoma cells to cisplatin. Inhibition of melanoma inhibitor of apoptosis protein mRNA and protein expression were measured by real-time polymerase chain reaction and immunoblotting. Cell viability and apoptosis were quantitated by colorimetric viability assays and by annexin V staining, respectively. Oligonucleotide M706 was identified as the most efficient antisense sequence which downregulated melanoma inhibitor of apoptosis protein mRNA and protein levels in G361 cells by 68 and 78%, respectively. The specificity of target downregulation was confirmed using scrambled sequence control oligonucleotides that only marginally decreased melanoma inhibitor of apoptosis protein expression. Whereas downregulation of melanoma inhibitor of apoptosis protein moderately inhibited cell growth by 26%, in combination with cisplatin, this resulted in a supra-additive effect with almost 57% reduction in G361 cell viability compared with cisplatin alone (17%) (P<0.05). Cell death was mainly due to apoptosis as demonstrated by a 3- to 4-fold increase in annexin V-positive cells and typical morphological changes compared with controls. In summary, we describe a new antisense oligonucleotide that efficiently downregulates melanoma inhibitor of apoptosis protein expression and sensitizes melanoma cells to cisplatin.

Tissue-transplant fusion and vascularization of myocardial microtissues and macrotissues implanted into chicken embryos and rats

Cell-based therapies and tissue engineering initiatives are gathering clinical momentum for next-generation treatment of tissue deficiencies. By using gravity-enforced self-assembly of monodispersed primary cells, we have produced adult and neonatal rat cardiomyocyte-based myocardial microtissues that could optionally be vascularized following coating with human umbilical vein endothelial cells (HUVECs). Within myocardial microtissues, individual cardiomyocytes showed native-like cell shape and structure, and established electrochemical coupling via intercalated disks. This resulted in the coordinated beating of microtissues, which was recorded by means of a multi-electrode complementary metal-oxide-semiconductor microchip. Myocardial microtissues (microm3 scale), coated with HUVECs and cast in a custom-shaped agarose mold, assembled to coherent macrotissues (mm3 scale), characterized by an extensive capillary network with typical vessel ultrastructures. Following implantation into chicken embryos, myocardial microtissues recruited the embryo's capillaries to functionally vascularize the rat-derived tissue implant. Similarly, transplantation of rat myocardial microtissues into the pericardium of adult rats resulted in time-dependent integration of myocardial microtissues and co-alignment of implanted and host cardiomyocytes within 7 days. Myocardial microtissues and custom-shaped macrotissues produced by cellular self-assembly exemplify the potential of artificial tissue implants for regenerative medicine.

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.

Patients motives for choosing a physician: Comparison between conventional and complementary 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 Objective was to identify patients' expectations and reasons governing the choice of complementary medicine compared with conventional primary care (CONV). Methods The data were derived from the PEK study (Programm Evaluation Komplementärmedizin), which was conducted in 2002–2003 with 7879 adult patients and parents of 1291 underage patients, seeking either complementary (CAM) or conventional (CONV) primary care. The study was performed as a cross-sectional survey. The respondents were asked to document their (or their children's) self-perceived health status, reasons governing their choice, and treatment expectations. Physicians were practicing conventional medicine and/or complementary methods (homeopathy, anthroposophic medicine, neural therapy, and traditional Chinese medicine). Reasons governing the choice of physician were evaluated on the basis of a three-part classification (physician-related, procedure-related, and pragmatic/other reasons) Results and Discussion Patients seeing CAM physicians tend to be younger and more often female. CAM patients referred to procedure-related reasons more frequently, whereas pragmatic reasons dominated among CONV patients. CAM respondents expected fewer adverse side effects compared to conventional care patients. Conclusion The majority of alternative medicine users appear to have chosen CAM mainly because they wish to undergo a certain procedure; additional reasons include desire for more comprehensive treatment, and expectation of fewer side-effects.

New therapies for pneumococcal meningitis

The treatment of pneumococcal meningitis remains a major challenge, as reflected by the continued high morbidity and case fatality of the disease. The worldwide increase of penicillin-resistant pneumococci and more recently cephalosporin- and vancomycin-tolerant pneumococci has jeopardised the efficacy of standard treatments based on extended spectrum cephalosporins alone or in combination with vancomycin. This review provides a summary of newly developed antibiotics tested in the rabbit meningitis model. In particular, newer beta-lactam monotherapies (cefepime, meropenem, ertapenem), recently developed quinolones (garenoxacin, gemifloxacin, gatifloxacin, moxifloxacin) and a lipopeptide antibiotic (daptomycin) are discussed. A special emphasis is placed on the potential role of combination treatments with some of the new compounds, which are of interest based on the background of increasing resistance problems due to their often synergistic activity in the rabbit model of pneumococcal meningitis.
