Are internists in an non-prescriptive setting favourable to guidelines? A survey in a Department of Internal Medicine in Switzerland.

A cross-sectional anonymous postal survey was carried out in a Department of Internal Medicine in order to assess physicians' knowledge about and attitudes towards clinical practice guidelines and to evaluate the role of age in determining their use and opinions. The study took place in a Swiss University Hospital where exposure to guidelines had been limited. The questionnaire was sent to the 174 physicians of the Department. The response rate was 67% (116/174). The spontaneous definitions of guidelines were heterogeneous and referred to information of uncertain validity. Most participants, especially the younger groups of junior and senior residents, reported using guidelines and were favourable to their development. Less favourable attitudes were observed among senior staff physicians and consultants. For instance, the latter more often held the opinion that guidelines are too rigid to apply to individual patients, were likely to decrease physician reimbursement and to hamper research (respectively, 32% vs 24%, 50% vs 31% and 18% vs 7% when compared with the opinions of residents). In conclusion, in a non-prescriptive hospital setting, where the development, dissemination and implementation of guidelines are emerging, the concept of 'guideline' was heterogeneous. Despite generally positive attitudes towards guidelines, the opinion of senior staff physicians constitute a barrier to their dissemination and implementation

Appropriateness of gastrointestinal endoscopy: risk of complications.

The balance between risks and benefits of gastrointestinal endoscopy for a given patient is essential in defining the appropriate use of endoscopic procedures. The current literature suggests that gastrointestinal endoscopy infrequently results in major procedure-related morbidity and mortality, while cardio-respiratory events occur commonly. However, true complication rates may be underestimated due to inconsistencies in the types of complications reported. No formal reporting requirements exist, and most of the published studies on complications come from centres with highly-skilled endoscopists

Use of and irradiation from plain lumbar spine radiography in Switzerland.

Plain lumbar spine radiographic examination (LSRE) is frequently used in medical practice and delivers a high dose of ionising radiation. The objectives of the study were to determine the annual frequency of LSRE in Switzerland and its distribution according to practitioners' and patients' characteristics, as well as the related population dose of ionising radiation. Data were extrapolated from a nationwide questionnaire survey on radiation exposure resulting from medical imaging in 1998, involving physicians and other healthcare providers performing radiological examinations in Switzerland. An estimated number of 273,000 LSRE are performed annually in Switzerland (39 LSRE per 1000 inhabitants per year). The collective dose to the population due to LSRE was 1130 Sv (0.16 mSv per person per year). 50-60% of these procedures were performed to confirm or rule out a diagnosis, the majority (85%) in the context of an illness. LSRE is the third most frequent radiographic procedure performed and delivers the highest population dose of ionising radiation of any radiodiagnostic procedure. Efforts to reduce the frequency and the radiation dose of this procedure must be kept up, technically by optimising the equipment and radioprotection measures, and clinically by implementing evidence-based approaches to appropriate indications for this imaging technique

Patient use of the Internet for health care information in Switzerland.

The aim of this study was to examine for the first time the frequency of Internet use for medical purposes by patients in Switzerland. In 2001 over a period of one month, 1604 patients at 8 medical practices in Switzerland completed a self-administered questionnaire on their access to the Internet and any search for medical information using this media. The attending physician supplied the patient's diagnosis and information on the severity of the disorder motivating the visit using a separate questionnaire. 46% of the patients included in the study had a personal computer, 33% had an Internet connection and 10% used the Internet to find medical information. Age was inversely associated with the probability of having an Internet access, whereas educational level and command of the English language were factors directly associated with this. Among those patients with access to the Internet, young adults (25 to 44 years) and those with knowledge of the English language searched for medical information significantly more frequently. Furthermore, patients attending urban medical practices and those with a more severe level of disease more often sought health care information on the Internet. The proportion of patients in Switzerland who search for medical information on the Internet is similar to the rates observed in European English-speaking countries. The Internet allows patients to actively search for information concerning their own health problems but is not currently the most common source of information used by patients. Since health professionals generate, directly or indirectly, most of the medical information published on the Internet, additional research is needed to better understand patients' needs and expectations concerning medical information using this media

Quality of work incapacity assessment in the Swiss disability insurance system.

Quality of medical assessment of work incapacity has been poorly investigated, despite the enormous costs engendered by transient incapacity of work and permanent disability. This study examined some indices of quality from a stratified, random sample (n = 120) of assessments performed by expert assessors of the Swiss disability insurance. The distribution of work incapacity (WI) percentages over a 100% scale showed a clustering around key values significantly associated with financial disability benefits. The precision of WI, expressed as the level of quantitative exactness, was found to be high in 74% (95% CI: 66-82%) of current WI assessments, and in 62% (95% CI: 53-71%) of maximal WI assessments. Disagreement was observed in 17% of cases when comparing two ways of expressing WI by the same physician (95% CI: 10-23%). This exploratory study is limited by the general lack of objective criteria and standards. Further theoretical and empirical developments are needed to determine standardized criteria and clear guidelines for medical assessments of WI, as well as for evaluating their quality

Quality of care after acute coronary syndromes in a prospective cohort with reasons for non-prescription of recommended medications.

BACKGROUND: Adherence to guidelines is associated with improved outcomes of patients with acute coronary syndrome (ACS). Clinical registries developed to assess quality of care at discharge often do not collect the reasons for non-prescription for proven efficacious preventive medication in Continental Europe. In a prospective cohort of patients hospitalized for an ACS, we aimed at measuring the rate of recommended treatment at discharge, using pre-specified quality indicators recommended in cardiologic guidelines and including systematic collection of reasons for non-prescription for preventive medications. METHODS: In a prospective cohort with 1260 patients hospitalized for ACS, we measured the rate of recommended treatment at discharge in 4 academic centers in Switzerland. Performance measures for medication at discharge were pre-specified according to guidelines, systematically collected for all patients and included in a centralized database. RESULTS: Six hundred and eighty eight patients(54.6%) were discharged with a main diagnosis of STEMI, 491(39%) of NSTEMI and 81(6.4%) of unstable angina. Mean age was 64 years and 21.3% were women. 94.6% were prescribed angiotensin converting enzyme inhibitors/angiotensin II receptor blockers at discharge when only considering raw prescription rates, but increased to 99.5% when including reasons non-prescription. For statins, rates increased from 98% to 98.6% when including reasons for non-prescription and for beta-blockers, from 82% to 93%. For aspirin, rates further increased from 99.4% to 100% and from to 99.8% to 100% for P2Y12 inhibitors. CONCLUSIONS: We found a very high adherence to ACS guidelines for drug prescriptions at discharge when including reasons for non-prescription to drug therapy. For beta-blockers, prescription rates were suboptimal, even after taking into account reason for non-prescription. In an era of improving quality of care to achieve 100% prescription rates at discharge unless contra-indicated, pre-specification of reasons for non-prescription for cardiovascular preventive medication permits to identify remaining gaps in quality of care at discharge.

Natuurbalans 2008

De Natuurbalans schetst jaarlijks de toestand en trends in natuur en landschap en evalueert het gevoerde beleid De laatste vijftien jaar is de oppervlakte van natuurgebieden toegenomen en zijn de milieucondities voor de natuur verbeterd. In natuurgebieden treedt voorzichtig herstel van soorten op. Zonder aanvullend beleid is het herstel voor de meeste natuurdoelen echter onvoldoende om deze op tijd te halen. Thema van de Natuurbalans 2008 is ‘water’. De kwaliteit van zoetwaternatuur is overwegend matig. Die natuur zal de komende 20 jaar profiteren van voorgenomen beleid voor het verbeteren van de kwaliteit van het oppervlaktewater. Juist voor de natte natuurgebieden waarvoor Europese afspraken over duurzaam behoud van biodiversiteit gelden, is echter aanvullend beleid nodig. Om de natuurdoelen voor de zee te bereiken, zijn drie acties noodzakelijk: verduurzaming van de visserij, verbetering van de waterkwaliteit en herstel van de natuurlijke dynamiek in het deltagebied en langs de Waddenzee. Voor de Noordzee is ook de ruimtelijke inrichting van belan
