Some aspects of the reform of the health care systems in Austria, Germany and Switzerland.

The health care systems in Austria, Germany and Switzerland owe their institutional structure to different historical developments. While Austria and Germany voted for the Bismarck-Model of social health insurance, Switzerland adopted a voluntary system of health insurance. In all three countries, until very recently, the different challenges which the health care sector faced were met by piecemeal approaches and by stop and go policies, which, in the long run were not very successful either in containing costs or in improving efficacy and efficiency. During the 1990 more fundamental reforms in the health care systems of all three countries took place. Germany and Switzerland chose the path of deregulation of the health insurance system, which consequently strengthened the competition between the insurance companies, and, to some extent between the suppliers of medical services. While this can be seen as an essential part of the reform process for these two countries. Austria favors a state-oriented and interventionist approach in order to meet the challenges.

Ammonia monitoring in Switzerland with passive samplers: patterns, determinants and comparison with modelled concentrations.

Gaseous ammonia (NH3) is an important form of N deposition to ecosystems, but it is not being routinely monitored in Switzerland. Therefore, a study was conducted to estimate annual means and seasonal patterns of NH3 concentrations for different site types in Switzerland, and to compare annual measured and modelled NH3 concentrations. NH3 concentrations were measured using the 'Zürcher' passive sampler, a Palmes type sampler with an acidic solution as absorbent. Twenty-four sampling sites were run for one year, and 17 for two years. The samplers were changed fortnightly or monthly. Spatial emission patterns were mapped by combining information on (1) the location of emission sources, (2) national statistics on NH3-emitting activities and (3) activity-specific emission factors. The spatial resolution was one hectare. The mean annual NH3 concentration in the ambient air of the 41 sites was 2.5+/-0.3 microg m(-3) (mean+/-standard error). It ranged from 0.4 to 7.5 microg m(-3). The site type and the season were the most important factors explaining the variation in the seasonal mean concentration. NH3 concentrations were highest in intensively used agricultural areas and in cities, and lowest in Alpine sites remote from emission sources. At 39 out of 41 sites, the NH3 concentrations were higher in summer (3.1+/-0.3 microg m(-3)) than in winter (2.0+/-0.3 microg m(-3)). Modelled NH3 concentrations did not systematically deviate from measured concentrations (r2 = 0.69). With the combined monitoring and modelling approach, it is now possible to obtain a reasonable and consolidated picture of the overall NH3 situation in Switzerland.

[Twelve years experience in Switzerland: Quo vadis BSE?].

When the first BSE case in Switzerland became public in 1990, it precipitated a chain of events with many diverse consequences. During this time, we continued to gain knowledge, implement new measures, and make practical recommendations in order to attempt to control the disease. This was made possible by the establishment of a huge data base containing information on all cases of BSE that had been diagnosed in Switzerland, as well as by the use of information from experiences in other countries. Analysis of these data allowed the sequence of events to be described temporally and spatially and an epidemiological evaluation to be made. These data also allow predictions to be made regarding the future of BSE in Switzerland, although these predictions must be interpreted cautiously.

[Impact and risks of cost cutting programs on the quality of hospital care in Switzerland].

Cost-minimization programs in Switzerland either in the public or the private sector have impact on quality and accessibility of the health care system. Rationalization may induce in fact hidden rationing of care and increases the workload of the health care workers involved. The relation of hospital staffing to inpatient quality of care are important issues. The reduction of funds may place patients at risk, due to lower staffing levels. Patient to nurses ratio have a substantial effect on inpatient mortality and nurse burnout. Research in Switzerland is needed to define the measurement of the nursing case mix on the basis of discharge data and to elucidate the factors influencing the staffing levels of nurses and the mix of nursing personnel in hospitals. Due to reduced funding the ability of hospitals to handle emergency cases may be compromised. The impact on quality and risks of unreflected cost minimization programs in hospitals but also the whole health care system are important and worth of public notice. Possible solutions for a health care reform in Switzerland are outlined and discussed.

[5 years ATLS (Advanced Trauma Life Support) courses in Switzerland].

Five years ATLS (Advanced Trauma Life Support) in Switzerland are analysed, the problems are discussed and the changes during this period are demonstrated. ATLS Switzerland is a part of the Swiss surgical Society, introduced by the ATLS International Faculty in 1998. Switzerland with 4 official languages needs a special structure. For this reason a decentralisation of the courses was necessary with the need of five regional universities where ATLS courses are offered. Statistics of the rising amount of courses demonstrate the enormous rush for ATLS courses in our country. Three courses in 1998 where followed by six courses in 1999, up to 18 courses in 2002. 2001 was the first year with ATLS in the Swiss Army. Since 1.1.2003 Paul Martin Sutter, Biel ist the new National Director, successor of Domenic Scharplatz, Thusis.

Use of army weapons and private firearms for suicide and homicide in the region of Basel, Switzerland.

OBJECTIVES: Switzerland has one of the highest rates of firearm suicides in the world. International studies show a positive correlation between the rate of households with guns and femicides with guns. Because its defense system requires a militia to keep personal firearms at home, Switzerland has a high rate of households with a gun. METHODS: Records of suicides in the region of Basel between 1992 and 1996 were reviewed. Suicides with either army weapons or private firearms and suicides by other means were compared. Methods and types of homicides that occurred in the region at the same time were also analyzed. FINDINGS: Firearm suicides were clearly the most frequent means of suicide. They were also used in 30.0% of domestic homicides, although other means were used at similar rates. Firearms for suicide were mainly used by men, especially army weapons. These men were younger, professionally better qualified, and fewer had ever been treated in one of the local state psychiatric services. DISCUSSION: The use of firearms for suicide, rather than homicide, and particularly of army weapons by young, well-educated men, requires more attention in debates and informed policy regarding access to firearms and suicide prevention in Switzerland.

The economic burden of asthma: direct and indirect costs in Switzerland.

Asthma mortality increased in Switzerland between 1980 and 1994. This study aimed to assess the economic burden of asthma in this country. Chart reviews were conducted for the last five patients seen for asthma in physician practices in 1996 and 1997. Direct expenditures and indirect costs for asthma-related morbidity were determined. A total of 589 patient charts were completely analysed, including 117 children's charts, obtained from 120 office-based physicians. The annual direct medical costs were CHF 1,778 and the mean annual indirect costs were CHF 1,019 per patient for all patients. The total estimated cost of asthma in Switzerland in 1997 was nearly CHF 1,252 million. Direct medical expenditures approached CHF 762 million, or 61% of the total. In 1997, the indirect costs for asthma were estimated to have exceeded CHF 490 million. Of these costs CHF 123 million (25%) was associated with morbidity and nearly CHF 368 million (75%) was associated with looking after asthmatic patients who had to be cared for at home. This study provides evidence that asthma is a major healthcare cost factor in Switzerland, amounting to approximately CHF 1,200 million per year. The data suggest that cost savings can be achieved by improving primary care for asthma in an ambulatory setting.

Seasonality in affective disorders in Switzerland.

OBJECTIVE: To estimate the prevalence of seasonal affective disorder (SAD) and its subsyndromal form (S-SAD) in Switzerland (47 degrees N). METHOD: A representative sample from all three language areas of Switzerland (n = 980) were given a structured telephone interview using the extended Seasonal Pattern Assessment Questionnaire (SPAQ+). A smaller, but also representative sample in the city of Basel filled in the SPAQ+ form as well as undergoing a structured diagnostic interview. RESULTS: In this Swiss sample, 2.2% of the population presented with symptom severity of SAD, 8.9% with S-SAD. In Basel, a much higher prevalence of SAD was found. Seasonal problems occurred more often in patients with the Diagnostic and Statistical Manual (DSM)-III diagnosis of major affective disorders than in those with pure anxiety disorders or no psychiatric diagnosis. CONCLUSION: These estimates for SAD in Switzerland are similar to those found in the Zürich Study, using other methods, and for populations in the UK, with the limitations inherent in retrospective questionnaire studies.

Electronic games and environmental factors associated with childhood obesity in Switzerland.

OBJECTIVE: Environmental factors and behaviors associated with obesity have not been well described in children living in Europe. Although television watching has been repeatedly associated with obesity, it is unclear whether other sedentary activities, such as use of electronic games, are independently associated with obesity in children. The hypothesis was that various types of sedentary activities are associated with obesity in children living in Switzerland. RESEARCH METHODS AND PROCEDURES: This was a cross-sectional study of children (grades one to three) from four communities in the Greater Zurich Area (Switzerland). Obesity was defined as a combination of overweight (BMI) and overfat (skinfold thicknesses). Environmental factors were assessed by questionnaire. The children's physical activity was estimated by their teacher (scale 0 to 10). RESULTS: Of 922 eligible subjects, 872 (94.6%) took part in the study. Use of electronic games [odds ratio (OR) = 2.03 per hour per day, 95% confidence interval (CI): 1.57 to 2.61, p < 0.001], television (OR = 2.83 per hour per day, 95% CI: 2.08 to 3.86, p < 0.001), physical activity (OR = 0.80 per unit, 95% CI: 0.72 to 0.88, p < 0.001), maternal work (OR = 1.93, 95% CI: 1.13 to 3.29, p = 0.02), and paternal smoking (OR = 1.78, 95% CI: 1.07 to 2.96, p = 0.03) were independently associated with obesity. Further adjustment for socioeconomic status, when available, did not change these results. DISCUSSION: In this sample of children living in Switzerland, the use of electronic games was significantly associated with obesity, independently of confounding factors. The association of obesity with television use and lack of physical activity confirms results from other populations and points to potential strategies for obesity prevention.

Obesity in Switzerland: a critical assessment of prevalence in children and adults.

The objective was to analyze the situation in Switzerland regarding the prevalence of overweight or obesity in children, adolescents and adults. The data were compared with France, an adjacent much larger country. The results showed that there is a definitive lack of objective information in Switzerland on the prevalence of obesity at different ages. As in other European studies, the fact that many national surveys are classically based on subject interviews (self-reported weights and heights rather than measured values) implies that the overweight/obesity prevalence is largely underestimated in adulthood. For example, in a recent Swiss epidemiological study, the prevalence of obesity (BMI greater than 30 kg/m(2)) averaged 6-7% in young men and women (25-34 y), the prevalence being underestimated by a factor of two to three when body weight was self-reported rather than measured. This phenomenon has already been observed in previous European studies. It is concluded that National Surveys based on telephone interviews generally produce biased obesity prevalence results, although the direction of the changes in prevalence of obesity and its evolution with repeated surveys using strict standardized methodology may be evaluated correctly. Therefore, these surveys should be complemented by large-scale epidemiological studies (based on measured anthropomeric variables rather than declared) covering the different linguistic areas of Switzerland. An epidemiological body weight (BMI) monitoring surveillance system, using a harmonized methodology among European countries, would help to accurately assess differences in obesity prevalence across Europe without methodological bias. It will permit monitoring of the dynamic evolution of obesity prevalence as well as the development of appropriate strategies (taking into account the specificity of each country) for obesity prevention and treatment.

Transplant legislation: ethical and practical issues in liver allocation--The case of Switzerland.

Ethical and practical issues relating to liver allocation have been discussed in many countries. Several governments, including the United States, have attempted over the past few years to impose new legislation, which has resulted in virulent debates among individual centers, organ procurement agencies, states, and various groups of interest. This report discusses the current ongoing legislative process in Switzerland. In 1999, the people of Switzerland voted to develop transplant legislation. This reflected the need to regulate poorly defined practices to adapt to the rapid progress within the field of transplantation. The main issue facing the Swiss transplant community is whether new legislation will allow medical evolution in organ allocation criteria without creating regulations that may become outdated with time. In addition, public debate has been shown to have a negative impact on organ donation, thus emphasizing an ever-present penury in cadaveric allografts. This article discusses these issues within the context of liver transplantation in Switzerland and also raises the uniform ethical and practical constraints placed on the medical transplant community in the face of an organ shortage.

[The predictive quality of the Psychopathy Checklist-Revised (PCL-R) for violent and sex offenders in Switzerland. A validation study].

In Switzerland, the Hare Psychopathy Checklist-Revised (PCL-R) is administered rather restrictively for risk assessment of recidivism among violent and sexual offenders. The aim of the present study was a first-time evaluation of the predictive validity of the PCL-R for violent and sexual recidivism in Switzerland. The PCL-R scores of 96 violent and sex offenders were evaluated by collecting the data in their psychiatric expert opinions. The scores were then compared to the rates of recidivism as shown in the criminal records. Consistent with previous studies in North America and Europe, the determined predictive accuracy was satisfying. This degree of precision supports the use of the PCL-R for risk assessment of sexual and violent recidivism in Switzerland, as long as the instrument does not constitute the sole criterion to determine future recidivism, but is applied only in combination with a thorough clinical evaluation. The use of precise cut-off scores did not prove to be a valid criterion for the prognosis of recidivism and can therefore not be recommended for Swiss offenders.

Use of the inactivated intranasal influenza vaccine and the risk of Bell's palsy in Switzerland.

BACKGROUND: After the introduction of an inactivated intranasal influenza vaccine that was used only in Switzerland, 46 cases of Bell's palsy were reported. METHODS: We conducted a matched case-control study and a case-series analysis. All primary care physicians, ear, nose, and throat specialists, and neurologists in German-speaking regions of Switzerland were requested to identify cases of Bell's palsy diagnosed in adults between October 1, 2000, and April 30, 2001. Each physician was invited to select three control patients for each patient with Bell's palsy, with matching according to age, date of the clinic visit, and physician. Vaccination information was provided by the physicians. RESULTS: A total of 773 patients with Bell's palsy were identified. Of the 412 (53.3 percent) who could be evaluated, 250 (60.7 percent) were enrolled and matched with 722 control patients; the other 162 patients had no controls. In the case-control study, we found that 68 patients with Bell's palsy (27.2 percent) and 8 controls (1.1 percent) had received the intranasal vaccine (P<0.001). In contrast to parenteral vaccines, the intranasal vaccine significantly increased the risk of Bell's palsy (adjusted odds ratio, 84.0; 95 percent confidence interval, 20.1 to 351.9). Even according to conservative assumptions, the relative risk of Bell's palsy was estimated to be 19 times the risk in the controls, corresponding to 13 excess cases per 10,000 vaccinees within 1 to 91 days after vaccination. In the case-series analysis, the period of highest risk was 31 to 60 days after vaccination. CONCLUSIONS: This study suggests a strong association between the inactivated intranasal influenza vaccine used in Switzerland and Bell's palsy. This vaccine is no longer in clinical use.

Behçet's disease in Western Switzerland: epidemiology and analysis of ocular involvement.

PURPOSE: To determine the epidemiology of Behçet's disease in Western Switzerland and to study the characteristics of ocular disease. METHODS: Patients newly diagnosed with Behçet's disease, seen from January 1990 to December 1998 at Hôpital Jules Gonin, La Source Eye Center, and the Division of Immunology and Allergy, University of Lausanne, were analyzed. The Japanese diagnostic criteria for Behçet's disease were used and both complete and incomplete forms were included. Incidence, proportion of cases with ocular involvement, and the characteristics of ocular disease were determined. RESULTS: During the follow-up period, a total of 35 Behçet's patients were seen in the three study centers. Twenty-five of these patients had ocular involvement. The incidences of Behçet's disease and Behçet's ocular disease in the western part of Switzerland, with a referral population of roughly 600000 persons, were 0.65 and 0.46 per 100000 per year, respectively. The mean age of the group was 33.2 years, age at presentation was 25.8 years, and mean follow-up was 5.7 years. The most frequent sign was oral aphthous involvement (86%), followed by ocular manifestations (72%). The HLA-B51 antigen was present in 66% of the patients with ocular involvement. Panuveitis was present in 20/25 patients (80%), anterior uveitis in 3/25 patients, and posterior involvement in 2/25 patients. Twenty-two patients (88%) had systemic treatment that always included corticosteroids; it was associated with other treatments in 17/22 patients. Mean duration of treatment was 45.5 +/- 25.1 (SD) months. The mean recurrence-free period in the six patients in whom treatment could be interrupted was 18.0 +/- 8.8 (SD) months. Visual function was maintained at the end of the follow-up for the collective and visual outcome was correlated to visual function at presentation. CONCLUSIONS: The incidence of Behçet's disease in Western Switzerland was comparable to that in other western nonendemic countries. With early diagnosis and appropriate therapy, the prognosis was favorable in our collective of patients.

Swiss Hypertension and Risk Factor Program (SHARP): cardiovascular risk factors management in patients with type 2 diabetes in Switzerland.

The prevalence of hypertension in type 2 diabetics is high, though there is no published data for Switzerland. This prospective cohort survey determined the frequency of type 2 diabetes mellitus associated with hypertension from medical practitioners in Switzerland, and collected data on the diagnostic and therapeutic work-up for cardiovascular risk patients. The Swiss Hypertension And Risk Factor Program (SHARP) is a two-part survey: The first part, I-SHARP, was a survey among 1040 Swiss physicians to assess what are the target blood pressure (BP) values and preferred treatment for their patients. The second part, SHARP, collected data from 20,956 patients treated on any of 5 consecutive days from 188 participating physicians. In I-SHARP, target BP?135/85 mmHg, as recommended by the Swiss Society of Hypertension, was the goal for 25% of physicians for hypertensives, and for 60% for hypertensive diabetics; values >140/90 mmHg were targeted by 19% for hypertensives, respectively 9% for hypertensive diabetics. In SHARP, 30% of the 20,956 patients enrolled were hypertensive (as defined by the doctors) and 10% were diabetic (67% of whom were also hypertensive). Six per cent of known hypertensive patients and 4% of known hypertensive diabetics did not receive any antihypertensive treatment. Diabetes was not treated pharmacologically in 20% of diabetics. Proteinuria was not screened for in 45% of known hypertensives and in 29% of known hypertensive diabetics. In Switzerland, most physicians set target BP levels higher than recommended in published guidelines. In this country with easy access to medical care, high medical density and few financial constraints, appropriate detection and treatment for cardiovascular risk factors remain highly problematic.

Variation in survival after diagnosis of breast cancer in Switzerland.

BACKGROUND: Survival after diagnosis of cancer is a key criterion for cancer control. Major survival differences between time periods and countries have been reported by the EUROCARE studies. We investigated whether similar differences by period and region existed in Switzerland. METHODS: Survival of 11,376 cases of primary invasive female breast cancer diagnosed between 1988 and 1997 and registered in seven Swiss cancer registries covering a population of 3.5 million was analysed. RESULTS: Comparing the two periods 1988-1992 and 1993-1997, age-standardized 5 year relative survival improved globally from 77% to 81%. Furthermore, multivariate analysis adjusting for age, tumour size and nodal involvement identified regional survival differences. Survival was lowest in the rural parts of German-speaking eastern Switzerland and highest in urbanised regions of the Latin- and German-speaking northwestern parts of the country. CONCLUSIONS: This study confirms that survival differences are present even in a small and affluent, but culturally diverse, country like Switzerland, raising the issue of heterogeneity in access to care and quality of treatment.

Mortality by education in German speaking Switzerland, 1990-1997: results from the Swiss National Cohort.

BACKGROUND: The aim of this paper is to show for the first time mortality differentials by level of education for Swiss men and women. This work is of interest to public health efforts in Switzerland as well as for co-operative international research into the determinants of socioeconomic differentials in health and mortality. METHODS: This study is based on a longitudinal data set from the Swiss National Cohort, currently incorporating a probabilistic record linkage of the 1990 Swiss census, and all subsequent deaths until the end of 1997. The study population covers all Swiss nationals aged >/=25 years living in German speaking Switzerland, with 19.7 million person-years and 296 929 deaths observed. Educational gradients were analysed using standardized mortality ratios, multiple logistic regression, and the Relative Index of Inequality (RII). RESULTS: There were sizeable gradients in mortality by education for all age groups and both sexes. The mortality odds ratio decreased by 7.2% (95% CI: 7.0-7.5%) per additional year of education for men, and by 6.0% (95% CI: 5.6-6.3%) for women. In men, we found a steady decrease of the gradient from 13.1% (95% CI: 11.9-14.4%) in the age group 25-39 to 4.5% (95% CI: 4.0-5.0%) in the age group >/=75 years. For women in the age groups under 65 the gradients were smaller; over the age of 40 there was no decrease with increasing age. These results were fairly insensitive to variations in the parameters of record linkage. CONCLUSIONS: Despite a comparatively low overall mortality, Swiss men in the 1990s show larger relative gradients in mortality by education than men in other European countries in the 1980s, with the possible exception of younger men in Italy. In Switzerland there is a sizeable potential for further increasing overall life expectancy by reducing the mortality of those with a lower educational level. The results presented contribute to a reliable assessment of socioeconomic mortality differentials in Europe.

Years of life lost attributable to air pollution in Switzerland: dynamic exposure-response model.

BACKGROUND: There is debate on how the effect of air pollution should be assessed. We propose an approach to estimate its impact on adult and infant mortality that integrates data from long-term epidemiological studies and studies of interventions to reduce pollution. We use the method to estimate the number of years of life lost (YLLs) attributable to air pollution during 1 year in Switzerland. METHODS: A dynamic exposure-response model was implemented, which uses an exponential function (exp(-kt)) to model the change in mortality after cessation of air pollution. The model was populated with relative risk estimates and estimates of time constant k from the literature. Air pollution exposure in Switzerland was modelled using data from emission inventories. YLLs attributable to air pollution were calculated by taking the difference between observed survival probabilities in Switzerland in 2000 and modified survival probabilities, assuming no air pollution during the year 2000. RESULTS: Meta-analyses of three studies of adult mortality and five studies of infant mortality gave relative risks of 1.059 (95% confidence interval (CI) 1.031-1.088) and 1.056 (95% CI 1.026-1.088) per 10 mug/m(3) increase in PM10 concentration. Time constants k derived from two studies of the effects of the closing down of a steel mill in the Utah Valley and of the coal ban in Dublin were 0.88 and 0.11. Assuming a time constant k of 0.5 resulted in 42 400 (95% CI 22 600-63 600) YLLs, with 4.0% being ascribed to infant deaths. A total of 39% of the effect occurred in the same year and 80% within 5 years. The estimated number of YLLs was little affected by the choice of the time constant. CONCLUSIONS: In contrast to traditional steady-state models the dynamic model allows changes in mortality following short-term increases or decreases in air pollution levels to be quantified. This type of information is of obvious interest to policy makers.
