Influence of physicians' life stances on attitudes to end-of-life decisions and actual end-of-life decision-making in six countries.

AIM: To examine how physicians' life stances affect their attitudes to end-of-life decisions and their actual end-of-life decision-making. METHODS: Practising physicians from various specialties involved in the care of dying patients in Belgium, Denmark, The Netherlands, Sweden, Switzerland and Australia received structured questionnaires on end-of-life care, which included questions about their life stance. Response rates ranged from 53% in Australia to 68% in Denmark. General attitudes, intended behaviour with respect to two hypothetical patients, and actual behaviour were compared between all large life-stance groups in each country. RESULTS: Only small differences in life stance were found in all countries in general attitudes and intended and actual behaviour with regard to various end-of-life decisions. However, with regard to the administration of drugs explicitly intended to hasten the patient's death (PAD), physicians with specific religious affiliations had significantly less accepting attitudes, and less willingness to perform it, than non-religious physicians. They had also actually performed PAD less often. However, in most countries, both Catholics (up to 15.7% in The Netherlands) and Protestants (up to 20.4% in The Netherlands) reported ever having made such a decision. DISCUSSION: The results suggest that religious teachings influence to some extent end-of-life decision-making, but are certainly not blankly accepted by physicians, especially when dealing with real patients and circumstances. Physicians seem to embrace religious belief in a non-imperative way, allowing adaptation to particular situations.

[Forgoing life-sustaining measures in patients at the end of life in the German-speaking part of Switzerland: results of a death certificate study]. / Begrenzung lebenserhaltender Massnahmen bei Patienten am Lebensende in der deutschsprachigen Schweiz -- Resultate einer Todesfallstudie.

BACKGROUND AND OBJECTIVE: There have not been any comprehensive data from German-speaking countries on the medical practice of withholding or withdrawing treatment at the end of life. This study from the German-speaking part of Switzerland provides the first in-depth analysis in this field. This study is based on data from this region and is a contribution to a large empirical research project on medical end-of-life decisions in 6 European countries (EURELD). METHODS: Continuous random samples (n = 4991) were taken from all deaths in the German-speaking part of Switzerland that had been reported to the Swiss Federal Office of Statistics between June and October 2001. Doctors who had been attending the deceased person were asked to complete mailed questionnaires, their replies being kept strictly anonymous. RESULTS: The response rate was 67 %. Medications were withheld or withdrawn in 48 % of all treatments forgone: among these, antibiotics accounted for 17 %. Other potentially life-sustaining medical measures forgone included artificial hydration (12 %), surgery (7 %), artificial feeding (6 %), chemotherapy (6 %), diagnostic tests (4 %), hospital admissions (3 %), renal dialysis (2 %), blood product infusions (2 %), intubation (2 %), ventilation (2 %), resuscitation (2 %), and radiotherapy (1 %). 43 % of all treatments were forgone in patients who died in hospital, 42 % in nursing homes, and 15 % at home. In almost three-quarters (73 %) of the treatments forgone, a primary-care doctor had ordered the treatment to be withheld or withdrawn. On average, forgoing treatment led to a life-shortening effect of more than one month in 8 % of all cases. The proportion was higher for renal dialysis (25 %), blood products infusion (18 %), and diagnostic tests (16 %). CONCLUSIONS: Forgoing life-sustaining medical treatment comprises a wide range of decisions taken in many different clinical settings. In most cases the likely lifespan is only slightly shortened.

[Place of death: "Where do people die in Switzerland nowadays?"]. / Der Sterbeort: "Wo sterben die Menschen heute in der Schweiz?"

BACKGROUND: Official information on the place of death has not been collected by the Swiss Federal Office of Statistics since 1987. Thus, no statements can be made for the developments in Switzerland. METHODS: Physicians from the German speaking part of Switzerland who had filled in a death certificate between June 1 and October 30, 2001 were sent a questionnaire about circumstances of the specific death case. The frequencies of the place of death (at home, in hospital, in home for elderly, in nursing home, other place) were compared with the official data of the years 1969 until 1986. Using logistic regressions predictors for the place of death were estimated. RESULTS: In 2001 in the German speaking part of Switzerland death occurred most frequently in hospital (37.2% of all death cases) followed by a home for elderly (33.5%) and dying at home (22.7%). Relevant predictors for the place of death were cause of death, sex, marital status and partly religion. Whereas between 1969 and 1986 a development towards dying in institutions was found, between 1986 and 2001 the place of death shifted within the institutions from hospitals to homes for elderly. CONCLUSION: The relevance of the home for elderly as the place of death will further grow in the future. To allow people to fulfill the tasks of caring for their relatives at home the ambulant emergency services will have to be augmented and relatives have to be motivated and supported.

Screening mammographies in Switzerland: what makes female and male physicians prescribe them?

QUESTION UNDER STUDY: Physicians play a key role in motivating women to undergo mammography screening. In 1998 we assessed Swiss physicians' attitudes to mammography screening and their prescription behaviour in this regard. METHODS: All female physicians and every second male physician aged 50-69 who were either not board-certified or board-certified in general practice, internal medicine, or obstetrics/gynaecology were sent a questionnaire. The response rate was 50% and thus 738 questionnaires were included in this study. Of the study population 39% were female and 61% male physicians. The distribution of professional backgrounds was: 27% board-certified general practitioners; 23% board-certified internists; 11% board-certified gynaecologists; 39% not board-certified. RESULTS: 55% of all study participants were in favour of a mammography screening programme for women aged over 50 in Switzerland, but breast self-examination and clinical breast examination were judged to have a more positive impact on breast cancer survival. Among clinically practising physicians, 22% reported generally prescribing biannual screening mammographies for women aged 50-69. Irrespective of other determinants, physicians from the Italian- and French-speaking parts of Switzerland prescribed screening mammographies more often than their colleagues from the German-speaking part (odds ratio [OR] 2.5; 95% confidence interval [CI] 1.5-4.2). Clinical practice in obstetrics/gynaecology (OR 2.4; CI 1.3-4.2) and a self-reported high level of knowledge concerning mammography screening (OR 1.9; CI 1.1-3.2) were also positively associated with the prescription of screening mammography. CONCLUSIONS: Since mammography screening programmes exist in only three French-speaking cantons of Switzerland (VS; VD; GE), the gap in prescription of screening mammographies between French/Italian- and German-speaking regions must be narrowed to prevent a higher prevalence of side effects from opportunistic screening among German-speaking women. There is a need to educate physicians and the political community regarding the risks and benefits of mammography screening.

Methods of the National Check Bus Project.

OBJECTIVES: Prevention at the worksite is considered increasingly important. This paper describes the methods used in a nationwide prevention campaign performed at a large Swiss bank and a Swiss industrial company. The aim of this project was to encourage general health awareness among company employees. We also aimed to provide the companies with general health analyses of their staff as a basis for future health promotion. Furthermore, new screening methods were evaluated in the field of research. METHODS: Participation in the programme was voluntary and free of charge. The programme targeted all 25,243 employees of the two companies in all regions of Switzerland. A mobile unit was available on site. The programme included a written health questionnaire and medical examinations (e.g., blood pressure, blood tests, ultrasound of the common carotid artery, osteodensitometry, examinations of the eye, etc). Analysis of individual test results, information brochures, and a telephone information service were also provided. Based on the data of the individuals, the "health status" of the employees of the two companies was analysed. The companies did not have access to the data of the individuals. The programme ran from August 1996 to August 1998. RESULTS: With a total of 10,321 persons taking part in the project, the participation rate was 41%. For the different examinations offered, patterns of participation were identifiable that varied with age, hierarchical status within the concern, body mass index, and number of physical complaints of the employee. Some of the variables showed the same trend for different tests, while others showed opposite trends. CONCLUSIONS: Participation in worksite health promotion programmes is dependent on a complex system of individual and structural variables that need to be considered when planning worksite health promotion programmes. Consideration of specific target population characteristics, including motivations and incentives as well as structural constraints is likely to improve participation rates in worksite health promotion programmes among employees.

Health technology assessment of three screening methods in Switzerland.

OBJECTIVE: To describe the level of health technology assessments for three screening methods in Switzerland. METHODS: Analysis of documents and expert opinions on mammography screening, ultrasound examinations during normal pregnancy, and screening for prostate-specific antigen (PSA) with a focus on services provided, recommendations, formal regulations, national papers, projects, and formal assessments. RESULTS: Preventive services are explicitly recommended by the Swiss federal law on health insurance. Two routine ultrasound examinations during normal pregnancy as well as PSA analysis for men over 40 years of age on medical indication are covered by basic health insurance. Mammography screening every 2 years has been covered since 1997 for women over 50 years. A systematic screening program for mammography exists in the western part of Switzerland, and a nationwide program is planned. However, a national program may not come into being until a quality assurance program for evaluation is established, and a nationwide fee for reimbursement-to include all costs of such a program-is accepted by providers and insurers. CONCLUSION: According to the Swiss health insurance law, the effectiveness of mammography screening and ultrasound examinations during normal pregnancy have to be proven. Systematic evaluation of these screening methods is in preparation. PSA is not part of current evaluation. It can be concluded that health technology assessment in Switzerland is now required by law for several medical services. However, limited financial and personnel resources as well as the lack of disease registers may hamper progress in the near future.

Appropriateness and necessity research on the Internet: using a "second opinion system".

Appropriateness and necessity research of various procedures in medicine may be the most complex field of innovation in healthcare and technology assessment. Nevertheless, the appropriateness of the indication of any medical intervention is probably more important than the outcome since even ideal quality components of structures, processes and outcomes become irrelevant without a proper indication. The first part of our appropriateness initiative in interventional cardiology and gynecology was to formulate guidelines. To define the appropriateness for coronary angiography, coronary revascularization and hysterectomy, literature-based consensus methods were used. The second part was to disseminate the guidelines in a user-friendly manner via the Internet. Therefore, we relied on a system-driven query facility for propositional (experts) rules. The next part of the appropriateness initiative may be a user-friendly Internet-based data collection system to validate the national accepted guidelines. Most important may be that only data that is needed can be collected using a refined database technology. The described Second Opinion System can be found under: http:sos.inf.ethz.ch. Research on indications with data on clinical outcome may open new opportunities to validate indication guidelines using Internet/database technology for data analysis and browsing of decision graphs concerning clinical decision-making. This new technology facilitates the evaluation of appropriateness and necessity criteria in combination with clinical outcomes.

Health technology assessment in Switzerland.

Switzerland has a mixed public and private healthcare system. All citizens are enrolled in compulsory basic health insurance. A 1996 law allows people to choose among different sickness funds and managed care plans. The federal government is empowered to act on important health issues, but the 26 cantons have prime responsibility in health care and social welfare. They have their own laws on health care, hygiene, hospitals, and social welfare. These laws are not harmonized. The system is complex, with a mix of public (mainly hospitals) and private (mainly doctors' offices) providers. The health services are decentralized. Ambulatory care was traditionally provided in doctors' offices, but the last decade has seen the development of centers for day surgery, group practices, and managed care plans. Decisions on placement, location, and extension of services are decentralized. The payment system is very complex. Current trends include global budgets, cost analyses, and prices related to patient categories. However, coverage policy is developed centrally and includes both traditionally established services and new technologies. New technologies are added to the list only after evaluation by the Federal Coverage Committee. The coverage process integrates health technology assessment (HTA). Coverage can be granted in stages, including limited coverage and temporary coverage. Technologies and coverage can be reevaluated on the basis of registries or assessment information. The structure of the Swiss healthcare system does not lend itself to the establishment of a national HTA program. However, recent moves include the development of a coordinating mechanism for HTA in Switzerland.

[Quality of dispensation of prescription medication from the patients' point of view]. / Qualität der Medikamentendistribution aus Sicht der Patientinnen und Patienten.

A cross-sectional survey investigated quality relevant aspects of the most common distribution channels (pharmacies, self-dispensing physicians) for prescription drugs in Switzerland. A self-administered questionnaire focusing on consumers' behaviour, perception and priorities regarding the process of dispensation of prescriptive medication was mailed to a random sample of 3000 patients, aged 18 years or older, with regular intake of prescriptive medication. Chi-square analysis was performed on 1058 responses. 60% of the respondents received their medication mainly or exclusively from pharmacies and 40% from self-dispensing physicians. In German-speaking Switzerland 53% of participants received their prescription drugs exclusively or mainly from self-dispensing physicians, compared to only 10% in the French-speaking area (p = 0.00). This distribution confirms the existing differences in regulation of self-dispensation in these regions. Most of the patients took 2-4 prescriptive drugs a day. The French Swiss received slightly more prescriptive medication than the German Swiss (p = 0.05). 45% of the participants, especially women and people using a pharmacy, reported additional, usually occasional over-the-counter medication. Provision of technical information (41%), friendliness (19%), and the availability of drugs (19%) were valued most important when receiving prescription drugs and 96% of the participants were satisfied with the service. In consequence, the participants were strongly bound to their source of drug supply. Some 80% received instructions for use there. However, only half were informed about the purpose of the medication, drugs' side effects, or possible drug interactions. Physicians provided such information more often than pharmacy staff. This observation may be attributable to the double role played by the self-dispensers, who provide medical care and at the same time hand out the drug. In conclusion, patients' satisfaction is achieved equally by both medication channels. However, there is a need to improve counselling to ensure excellence in the supply of drugs.

[Quality control in patient education. Results of a patient survey about the patient education protocol of the Swiss Society of Surgery in 6 Swiss hospitals]. / Qualitätskontrolle der Patientenaufklärung. Resultate der Patientenbefragung über das Aufklärungsprotokoll der Schweizerischen Gesellschaft für Chirurgie (SGC) in sechs Schweizer Spitälern.

In the past years the number of malpractice suits due to lack of patient information has increased. Because there have been no generally accepted guidelines for preoperative patient information, the Swiss Society of Surgery has decided to work out an informative brochure tailored to the needs of patients. It takes into account that the need to know beforehand is increasing rapidly. In collaboration with the judiciary service of the Swiss Medical Federation all the items and points of legal relevance have been compiled to establish an informative brochure. Based on this protocol, patients in surgical departments of 6 Swiss community hospitals were asked before discharge to qualify the preoperative information offered to them. 2660 questionnaires were evaluated. The majority of patients considered the information regarding their diagnosis, the complications, risks, treatment and postoperative care, the sketches describing the operation and the overall degree of information as good or very good. Almost 60% of all patients stated that no alternative treatment had been discussed with them other than the planned procedure. In most of these patients operative procedures were chosen and carried out for which there were few or no other acceptable options. 2/3 of the patients asked for immediate preoperative written information, especially if they had malignant disease. Barely 4% of the patients were not reassured by the information provided to them. The fact that 2/3 of all patients re-read the informative protocol before the operation underlines how important it is to hand out a copy of the protocol to satisfy the informative needs of the patients. To our surprise the vast majority of patients uttered little concern about giving their signature to forms that were presented to them. Only 2% of the patients felt that giving a signature would cause them grave reservations. The informative protocol devised by the Swiss Society of Surgery is well adapted to the informative needs of the patients and allows for a structured conversation. It facilitates documentation and offers valid legal proof for the physician that he/she has provided adequate information.

The Swiss database on quality projects in medical institutions.

Since the early 1990s it is important for every medical institution to report on activities in the field of quality improvement and quality assessment because there is a certain pressure from the market and from health insurance laws in various countries. Nevertheless, researchers as well as clinicians or administrators are rarely informed on ongoing projects. To register projects in quality research, an Internet-based information system was established to register projects on quality of medical institutions. Among others, hospitals, private doctors' offices, medical specialty societies and cost-payers are regarded as institutions in this effort. An interactive database provides information on the institution performing a project and on what is being/has been performed in a certain place during a certain period of time. At present medical institutions are invited to report on their projects, but this initiative can only succeed if it provides information from as many different institutions as possible: for data skills and help your colleagues! Place your knowledge, activities and information at disposal to the public and profit from your colleagues.

[Possible future of the project for quality assurance of indications and outcome in interventional cardiology and gynecology]. / Die mögliche Zukunft der Projekte zur Qualitätssicherung der Indikationsstellung und der Ergebnisse in der interventionellen Kardiologie und der Gynäkologie.

In the last few years the basis for national guidelines for the indications of coronary angiography, coronary revascularisation and hysterectomy has been established. The guidelines have been published and are accessible to medical doctors and patients on the Internet using a database system called "Second Opinion System": http:/(/)sos.inf.ethz.ch Dissemination, implementation and validation of the guidelines will be of major importance in the near future. With reference to validation, the question remains whether the established guidelines are correct for the everyday treatment of patients. A suitable method of answering this important question is comparison between the appropriateness and necessity rates of the various indication groups, combined with outcome measurements. The Internet-based second opinion system (SOS) may be used for data collection in order to verify hypotheses. Because of the database architecture, only relevant information about the patients is collected via Internet, independent of time and place. In addition, the system allows users to evaluate their individual data, and special attention is given to data protection. The discussion about priorities in health care (rationing) will be increasingly important in the near future. The present project may offer a way of maintaining adequate access to health care services for patients. Therefore, the participation of as many institutions as possible in the project "quality assurance of indication and outcome in interventional cardiology and in gynaecology" is of great importance.

Swiss consensus guidelines for hysterectomy. Swiss Society of Gynecology and Obstetrics, Switzerland.

OBJECTIVE: The quality of the indication for hysterectomy is widely discussed at present. In early 1996, the committee for quality assurance of the Swiss Society of Gynecology and Obstetrics decided to set up nationally accepted guidelines for the indication of hysterectomy. METHODS: A modified Delphi approach was used. In a first step, general guidelines and actions prior to hysterectomy were defined. An expert panel of 17 Swiss gynecologists rated 74 frequent indications, twice for appropriateness (more benefits than risks for the patient), once for necessity (n = 34; procedure has to be offered or discussed with the patient), and outlined suggestions to be performed prior to hysterectomy. RESULTS: In a home rating round before the first panel met, there was an agreement rate of 48%. In 45% we observed neither agreement nor disagreement; in 7% we found disagreement. After the panel discussion 89% of experts agreed, 11% were indeterminate, and there was no disagreement. The necessity ratings showed agreement in 68% while 32% were indeterminate. The average median rating on a 1-9 point scale (1 = extremely inappropriate, 9 = extremely appropriate or necessary) was 5.4 over all single indications for appropriateness and 7.8 in single indications for necessity. After a second panel for consensus all panelists agreed on both appropriateness and necessity. CONCLUSION: The results of the appropriateness and necessity consensus presented in this paper reflect the findings of a 17 member Swiss panel. This joint effort by a medical society may be a step towards the direction of a peer controlled healthcare system.

Adaptive antioxidant response of manganese-superoxide dismutase following repetitive UVA irradiation.

In response to the attack of reactive oxygen species, the skin has developed a complex antioxidant defense system including among others the manganese-superoxide dismutase (MnSOD). MnSOD dismutates the superoxide anion (O2*-) derived from the reduction of molecular oxygen to hydrogen peroxide (H2O2), which is detoxified by glutathione peroxidase to water and molecular oxygen. We have addressed the question whether MnSOD is inducible upon UVA irradiation and whether repetitive UV exposure, as practiced for the light-hardening during phototherapy of various photodermatoses, can even enhance the adaptive antioxidant response. Single exposure of four different strains of fibroblasts to UVA irradiation resulted in a dose- and time-dependent increase in specific MnSOD mRNA levels. Interestingly, repetitive UVA exposure at days 1, 2, and 3 at a dose rate of 200 kJ per m2 resulted in a 5-fold induction of specific MnSOD mRNA levels following the third UVA exposure. Similar results were obtained for MnSOD activity. This adaptive response in terms of upregulation of the antioxidant enzyme MnSOD correlates with the protection against high UV doses, if cells were preexposed to sublethal UV doses. Importantly, MnSOD substantially differed between the tested individuals in both mRNA and activity levels. Taken together, we here provide evidence for the increasing induction of MnSOD upon repetitive UVA irradiation that may contribute to the effective adaptive UVA response of the skin during light hardening in phototherapy. Interindividual differences in the inducibility of MnSOD might account for differences in the susceptibility to develop photodermatologic disorders related to photosensitivity, photoaging, and skin cancer. The molecular basis for interindividual differences in the inducibility of antioxidant enzymes remains to be elucidated.

Psoralen photoactivation promotes morphological and functional changes in fibroblasts in vitro reminiscent of cellular senescence.

Premature aging of the skin is a prominent side effect of psoralen photoactivation, a treatment used widely for various skin disorders. The molecular mechanisms underlying premature aging upon psoralen photoactivation are as yet unknown. Here we show that treatment of fibroblasts with 8-methoxypsoralen (8-MOP) and subsequent ultraviolet A (UVA) irradiation resulted in a permanent switch of mitotic to stably postmitotic fibroblasts which acquired a high level of de novo expression of SA-beta-galactosidase, a marker for fibroblast senescence in vitro and in vivo. A single exposure of fibroblasts to 8-MOP/UVA resulted in a 5.8-fold up-regulation of two matrix-degrading enzymes, interstitial collagenase (MMP-1) and stromelysin-1 (MMP-3), over a period of >120 days, while TIMP-1, the major inhibitor of MMP-1 and MMP-3, was only slightly induced. This imbalance between matrix-degrading metalloproteases and their inhibitor may lead to connective tissue damage, a hallmark of premature aging. Superoxide anion and hydrogen peroxide, but not singlet oxygen, were identified as important intermediates in the downstream signaling pathway leading to these complex fibroblast responses upon psoralen photoactivation. Collectively, the end phenotype induced upon psoralen photoactivation shares several criteria of senescent cells. In the absence of detailed molecular data on what constitutes normal aging, it is difficult to decide whether the changes reported here reflect mechanisms underlying normal cellular aging/senescence or rather produce a mimic of cellular aging/senescence by quite different pathways.

Intrapartum reflectance pulse oximetry: effects of sensor location and fixation duration on oxygen saturation readings.

OBJECTIVE: To determine the effects of sensor location and suction fixation duration on measurements of intrapartum fetal oxygen saturation (SpO2) with a new reflectance pulse oximetry system. DESIGN: Fetal SpO2 values (n = 18) were determined in the first stage of labor before and after moving the sensor to another part of the fetal head. RESULTS: Mean fetal SpO2 values did not differ with sensor location (95% CI: -3.59 to 1.48). The duration of measurement period 1, before moving the sensor, was 104 +/- 44 (range 30-240) min. No time-dependent changes in SpO2 values were seen (r = 0.17). CONCLUSION: Suction is an effective and noninvasive method of securing the reflectance pulse oximetry sensor to the fetal head in the first stage of labor and does not interfere with reproducible SpO2 values over several hours.

Reflectance pulse oximetry in neonates.

OBJECTIVE: To test the feasibility and reliability in neonates of an in-house reflectance pulse oximetry (RPOX) system as an alternative method of non-invasive oxygen saturation monitoring when transmission pulse oximetry (TPOX) cannot be used, as in fetal scalp oxygen saturation monitoring during delivery. STUDY DESIGN: The study population consisted of 31 intensive care neonates. The RPOX sensor was attached by suction to the forehead, cheek, occiput and back; recordings were under simultaneous TPOX control. RESULTS: There was close agreement between RPOX and TPOX oxygen saturation and heart rate values, even in periodic breathing. RPOX signals from the back were unreliable because of breathing artifacts. Differences in mean absolute RPOX and TPOX oxygen saturation values were due to different calibrations. Both systems were equally sensitive to motion artifacts. CONCLUSION: As a feasible and reliable method of non-invasive oxygen saturation monitoring in neonates, RPOX has potential applications in fetal scalp monitoring.

Limitations of forehead pulse oximetry.

During initial clinical tests to calibrate our reflectance pulse oximetry system, we observed serious physiologic limitations to the use of pulse oximetry in the forehead region. We present a case of simultaneous reflectance and transmission mode pulse oximetry monitoring in a child undergoing cardiac surgery for congenital cyanotic heart disease with a large intracardiac shunt. During general anesthesia, when the patient was endotracheally intubated and mechanically ventilated, the transmission mode saturation agreed well with arterial oxygen saturation measurements; but, our reflectance pulse oximeter, with the sensor applied to the forehead, displayed spuriously lower (-18%) oxygen saturations. Before and after anesthesia and surgery, there was fine agreement between reflectance and transmission mode saturation values. We suggest that the difference was caused by vasodilatation and pooling of venous blood due to compromised venous return to the heart, and a combination of arterial and venous pulsations in the forehead region. This means that the reflectance pulse oximeter measured a mixed arterial-venous oxygen saturation.
