Prévalence des maladies infectieuses au Centre hospitalier universitaire vaudois [Prevalence of infectious diseases at the Vaud University Hospital Center].

The prevalence of infectious diseases at our hospital (Centre hospitalier universitaire vaudois, Lausanne [CHUV], 900 beds) was studied retrospectively over a two years period (1980-1981). The medical diagnosis of 30203 patients recorded in the computerized medical archives, representing 93% of the patients admitted during the period of observation, was reviewed. To assess the reliability of the computerized data, quality control was carried out through detailed analysis of all the histologically proven appendicitis recorded during 1981. 88% of the histologically proven appendicitis were registered in the computer and the diagnosis was specific in 87% of cases. An infectious disease was the primary reason for admission in 12.8% of the patients (3873) during the study period. Altogether, 20.2% of patients presented with an infection during their hospital stay. Because of the retrospective nature of the study it was not possible to determine whether these additional infections were nosocomially acquired. The organ systems most frequently infected were the respiratory tract (28.5% of all infections), the digestive tract (20.5%), the skin and osteoarticular system (16%) and the urogenital tract (11.6%). An infection was the primary reason for admission of 40.2% of the patients hospitalized in the dermatology service, of 19.7% of patients admitted in internal medicine, of 15-17% of the patients admitted in pediatrics, ENT and general surgery, and of 1-2% of the patients admitted in neurosurgery and radiotherapy. These observations highlight the continuing importance of infectious diseases in a modern hospital, in spite of high socio-economic levels, stringent hygiene and epidemiologic measures, and modern antibiotic availability.

Médecines complémentaires: vers un consensus evidence- based à l'hôpital universitaire [Complementary and alternative medicines (CAM): towards an evidence-based consensus in the university hospital].

While a popular vote supported a new article on complementary and alternative medicines (CAM) in the Swiss Constitution, this assessment in 14 wards of the University Hospital of Lausanne, Switzerland, attempted at answering the question: How can CAM use be better taken into account and patients informed with more rigor and respect for their choices? Confronted with a review of the literature (> 2000 publications in "Evidence-based complementary medicines" since 1998), respondents declared their ignorance of the clinical data presently available on CAM. All were in favour of more teaching and information on the subject, plus an official statement from the Hospital direction, ensuring production and diffusion of rigorous and clinically significant information on CAM.

Patients who attend a private practice vs a university outpatient clinic: how do they differ?

Although interpersonal continuity is commonly assumed to be essential for care, some patients prefer to attend a university outpatient clinic where physicians change regularly and interpersonal continuity of care is not ensured. The aim of this exploratory study was to evaluate the differences between patients attending a university outpatient clinic and patients frequenting a private practice, explore their patterns of care-seeking and their understanding of continued care. We conducted a cross-sectional study of patients attending the university medical outpatient clinic (OC) in Lausanne, Switzerland and ten randomly selected private general practices (PP). Eligible patients were >30 years, Swiss nationals or long term residents, with one or more chronic conditions and attending the same practice for >3 years. They were asked to complete a questionnaire on sociodemographic data, use of medical resources and reasons for choosing and remaining at the same practice. Semi-structured interviews were conducted with a randomly selected subset of 26 patients to further explore their preferences. 329 patient questionnaires were completed, 219 by PP and 110 by OC patients. OC patients tended to be of lower socioeconomic status than PP patients. The main reason for choosing a PP were personal recommendation, while a higher percentage of patients chose the OC because they could obtain a first appointment quickly. A higher percentage of PP patients accorded importance to physician communication skills and trust, whereas a higher percentage of OC patients favoured investigation facilities. Qualitative data suggested that although OC and PP patients reported different reasons for consulting, their expectations on the medical and relationship level were similar. Our study suggests that the two groups of patients belong to different social backgrounds, have different patterns of care-seeking and attach importance to different aspects of care continuity. However, patients' expectations and perceptions of the physician-patient relationship are similar.

How to operate a university institute as a radiological emergency service?

The Institute of Radiation Physics (IRA) is attached to the Department of Medical Radiology at the Vaud University Hospital Center (CHUV) in Lausanne. The Institute's main tasks are strongly linked to the medical activities of the Department: radiotherapy, radiodiagnostics, interventional radiology and nuclear medicine. The Institute also works in the fields of operational radiation protection, radiation metrology and radioecology. In the case of an accident involving radioactive materials, the emergency services are able to call on the assistance of radiation protection specialists. In order to avoid having to create and maintain a specific structure, both burdensome and rarely needed, Switzerland decided to unite all existing emergency services for such events. Thus, the IRA was invited to participate in this network. The challenge is therefore to integrate a university structure, used to academic collaborations and the scientific approach, to an interventional organization accustomed to strict policies, a military-style command structure and "drilled" procedures. The IRA's solution entails mobilizing existing resources and the expertise developed through professional experience. The main asset of this solution is that it involves the participation of committed collaborators who remain in a familiar environment, and are able to use proven materials and mastered procedures, even if the atmosphere of an accident situation differs greatly from regular laboratory routines. However, this solution requires both a commitment to education and training in emergency situations, and a commitment in terms of discipline by each collaborator in order to be integrated into a response plan supervised by an operational command center.

Artérite de Horton: recommandations Lausannoises de prise en charge [Giant cell arteritis: guidelines of the University Hospital of Lausanne].

L'artérite de Horton (AH), une vasculite subaiguë à chronique, est la plus fréquente des vasculites systémiques dans la population âgée de plus de 50 ans. L'absence de critères diagnostiques univoques, ajoutée au fait que le tableau clinique souvent complexe nécessite une prise en charge multidisciplinaire, conduit assez régulièrement à un retard thérapeutique. Il s'agit pourtant d'une maladie nécessitant un traitement urgent en raison du risque de cécité. Cet article présente une revue de l'AH et se conclut par des recommandations institutionnelles lausannoises concernant le diagnostic, la thérapie et la prise en charge multidisciplinaire. Giant cell arteritis (GCA) is a subacute/chronic vasculitis and represents the most common form of systemic vasculitis in people over the age of 50 years. The absence of clear and specific diagnostic criteria with the highly variable clinical presentation is a diagnostic challenge requesting a multidisciplinary approach. Yet, GCA is an emergency and the treatment must be initiated very rapidly due to the risk of blindness. This article presents a review of GCA as well as the diagnostic and therapeutic institutional guidelines of the University Hospital of Lausanne.

Students support demographically-based quotas with distributive justice rules favoring their selection at university

We manipulate distributive justice rules of demographic quotas in university selection. Results show that quotas involving students' need are preferred over equity and authority ranking quotas. International students also differentiate more between quotas than locals, preferring those advantaging them. This suggests that universities should consider students' need in their selection.
