Emergency department use by oldest-old patients from 2005 to 2010 in a Swiss university hospital.

BACKGROUND: Aging of the population in all western countries will challenge Emergency Departments (ED) as old patients visit these health services more frequently and present with special needs. The aim of this study is to describe the trend in ED visits by patients aged 85 years and over between 2005 and 2010, and to compare their service use to that of patients aged 65-84 years during this period and to investigate the evolution of these comparisons over time. METHODS: Data considered were all ED visits to the University of Lausanne Medical Center (CHUV), a tertiary Swiss teaching hospital, between 2005 and 2010 by patients aged 65 years and over (65+ years). ED visit characteristics were described according to age group and year. Incidence rates of ED visits and length of ED stay were calculated. RESULTS: Between 2005 and 2010, ED visits by patients aged 65 years and over increased by 26% overall, and by 46% among those aged 85 years and over (85+ years). Estimated ED visit incidence rate for persons aged 85+ years old was twice as high as for persons aged 65-84 years. Compared to patients aged 65-84 years, those aged 85+ years were more likely to be hospitalized and have a longer ED stay. This latter difference increased over time between 2005 and 2010. CONCLUSIONS: Oldest-old patients are increasingly using ED services. These services need to adapt their care delivery processes to meet the needs of a rising number of these complex, multimorbid and vulnerable patients.

Monthly wages in the Swiss Household Panel

This paper describes the construction of monthly income from employment and self employment in the Swiss Household Panel (SHP). It documents the assumptions that have to be taken and addresses possibilities and difficulties when relating monthly income variables with the number of working hours. Finally, some descriptive statistics of the monthly wages are provided from 1999 to 2008. These show a high correlation of wages across the years, which is higher than correlation from yearly wages. This underlies the suitability of these variables on monthly wages for labour market research with the SHP. Median and average hourly wages have increased slightly from 2002 to 2008. The inequality of wages has remained stable for the total population.

Impact of preoperative central neurologic dysfunction on patients undergoing emergency surgery for type a dissection.

BACKGROUND: Preoperative central neurologic deficits in the context of acute type A dissection are a complex comorbidity and difficult to handle. The aim this study was to analyze this subgroup of patients by comparing them with neurologically asymptomatic patients with type A dissection. Results may help the surgeon in preoperative risk assessment and thereby aid in the decision-making process. METHODS: We reviewed the data of patients admitted for acute type A dissection during the period from 1999 to 2010. Associated risk factors, time to surgery from admission, extension of the dissection, localization of central nervous ischemic lesions, and the influence of perioperative brain protective strategies were analyzed in a comparison of preoperative neurologically deficient to nondeficient patients. RESULTS: Forty-seven (24.5%) of a total of 192 patients had new-onset central neurologic symptoms prior to surgery. Concomitant myocardial infarction (OR 4.9, 95% CI 1.6-15.3, P = 0.006), renal failure (OR 5.9, 95% CI 1.1-32.8, P = 0.04), dissected carotid arteries (OR 9.2, 95% CI 2.4-34.7, P = 0.001), and late admission to surgery at >6 hours after symptom onset (OR 2.7, 95% CI 1.1-6.8, P = 0.04) were observed more frequently in neurologically deficient patients. These patients had a higher 30-day in-hospital mortality on univariate analysis (P = 0.01) and a higher rate of new postoperative neurologic deficits (OR 9.2, 95% CI 2.4-34.7, P = 0.02). Neurologic survivors had an equal hospital stay, and 67% of them had improved symptoms. CONCLUSIONS: The predominance of neurologic symptoms at admission may be responsible for an initial misdiagnosis. The concurrent central nervous system ischemia and myocardial infarction explains a higher mortality rate and a more extensive "character" of the disease. Neurologically deficient patients are at higher risk of developing new postoperative neurologic symptoms, but prognosis for the neurologic evolution of survivors is generally favorable.

Task force IV: Clinical use of ambulatory blood pressure monitoring. Participants of the 1999 Consensus Conference on Ambulatory Blood Pressure Monitoring

OBJECTIVE: To reach a consensus on the clinical use of ambulatory blood pressure monitoring (ABPM). METHODS: A task force on the clinical use of ABPM wrote this overview in preparation for the Seventh International Consensus Conference (23-25 September 1999, Leuven, Belgium). This article was amended to account for opinions aired at the conference and to reflect the common ground reached in the discussions. POINTS OF CONSENSUS: The Riva Rocci/Korotkoff technique, although it is prone to error, is easy and cheap to perform and remains worldwide the standard procedure for measuring blood pressure. ABPM should be performed only with properly validated devices as an accessory to conventional measurement of blood pressure. Ambulatory recording of blood pressure requires considerable investment in equipment and training and its use for screening purposes cannot be recommended. ABPM is most useful for identifying patients with white-coat hypertension (WCH), also known as isolated clinic hypertension, which is arbitrarily defined as a clinic blood pressure of more than 140 mmHg systolic or 90 mmHg diastolic in a patient with daytime ambulatory blood pressure below 135 mmHg systolic and 85 mmHg diastolic. Some experts consider a daytime blood pressure below 130 mmHg systolic and 80 mmHg diastolic optimal. Whether WCH predisposes subjects to sustained hypertension remains debated. However, outcome is better correlated to the ambulatory blood pressure than it is to the conventional blood pressure. Antihypertensive drugs lower the clinic blood pressure in patients with WCH but not the ambulatory blood pressure, and also do not improve prognosis. Nevertheless, WCH should not be left unattended. If no previous cardiovascular complications are present, treatment could be limited to follow-up and hygienic measures, which should also account for risk factors other than hypertension. ABPM is superior to conventional measurement of blood pressure not only for selecting patients for antihypertensive drug treatment but also for assessing the effects both of non-pharmacological and of pharmacological therapy. The ambulatory blood pressure should be reduced by treatment to below the thresholds applied for diagnosing sustained hypertension. ABPM makes the diagnosis and treatment of nocturnal hypertension possible and is especially indicated for patients with borderline hypertension, the elderly, pregnant women, patients with treatment-resistant hypertension and patients with symptoms suggestive of hypotension. In centres with sufficient financial resources, ABPM could become part of the routine assessment of patients with clinic hypertension. For patients with WCH, it should be repeated at annual or 6-monthly intervals. Variation of blood pressure throughout the day can be monitored only by ABPM, but several advantages of the latter technique can also be obtained by self-measurement of blood pressure, a less expensive method that is probably better suited to primary practice and use in developing countries. CONCLUSIONS: ABPM or equivalent methods for tracing the white-coat effect should become part of the routine diagnostic and therapeutic procedures applied to treated and untreated patients with elevated clinic blood pressures. Results of long-term outcome trials should better establish the advantage of further integrating ABPM as an accessory to conventional sphygmomanometry into the routine care of hypertensive patients and should provide more definite information on the long-term cost-effectiveness. Because such trials are not likely to be funded by the pharmaceutical industry, governments and health insurance companies should take responsibility in this regard.

Prévention primaire et dépistage chez l'adulte: mise à jour 2010. [Prevention and screening in adults: trends in 2010].

This article proposes an update on the recommendations for the check-up and the primary and secondary prevention of cancers and cardio-vascular diseases. Indeed, new clinical data led the adaptation and clarification of some of them. The novelties for cancer screening concern mainly colorectal, breast and prostate cancers. Screening for low ankle brachial index is not recommended.

"Etude rétrospective des cas de vasculite cutanée identifiés au laboratoire de dermopathologie du CHUV de 2006 à 2010"

CONTEXTE Les vasculites représentent un groupe de maladies inflammatoires touchant tous les vaisseaux, des grosses artères aux artères de plus petit calibre, en passant par les capillaires et les veines, de toutes tailles également. La taille des vaisseaux atteints est d'une importance cruciale pour le diagnostic puisque la classification actuelle en dépend. Sur le plan histopathologique, la vasculite est une réaction inflammatoire qui atteint la paroi de vaisseaux, et qui va entraîner alors une ischémie, puis une nécrose du vaisseau lui-­‐ même voire des structures environnantes ; les caractéristiques microscopiques de ces lésions permettent souvent d'aider à préciser le groupe auquel appartient la vasculite. Cependant, il n'est pas toujours facile ni possible d'obtenir un échantillon de tissu, une biopsie, selon l'endroit concerné (cerveau, régions profondes et difficilement accessibles...). OBJECTIFS Dans les atteintes de type « vasculite », la peau est fréquemment un organe cible. Le grand avantage est son accès direct et aisé, notamment dans le but de pratiquer un examen histopathologique par le biais d'une biopsie, qui peut se pratiquer de manière superficielle ou profonde, révélant alors des vaisseaux de différents calibres. Face à un tableau clinique parfois complexe et menaçant, il est important de pouvoir orienter le diagnostic rapidement. L'objectif de ce travail est donc de déterminer quelles sont l'utilité et l'apport de la biopsie cutanée dans le diagnostic des vasculites, et autrement dit de déterminer s'il vaut la peine de pratiquer ce genre d'examen, ou s'il vaut mieux privilégier d'autres approches plus rentables sur ce plan-­‐là. METHODES Grâce à l'aide des dermatologues et à la base de données du Service de dermatopathologie du CHUV, nous nous proposons de faire une étude rétrospective et systématique, sur les 5 années passées, de toutes les biopsies cutanées compatibles avec le diagnostic de vasculite. RESULTATS ESCOMPTES Ils sont de deux ordres : déterminer d'une part si le résultat de la biopsie était compatible avec le diagnostic clinique retenu chez les patients ayant subi ce type d'examen. Cela nous permettra alors d'établir des recommandations pour la réalisation éventuelle d'une biopsie cutanée dans ce type de situation. Il sera en effet capital de savoir si ce geste est utile et, le cas échéant, s'il faut demander une biopsie profonde ou si une biopsie superficielle est suffisante. Ce travail nous permettra d'autre part de revoir les caractéristiques cutanées -­‐ sur le plan histopathologique -­‐ des vasculites, et de déterminer aussi leur fréquence. Dans l'idéal, ce travail devrait permettre de faire la revue et la mise à jour des connaissances dans le domaine des vasculites cutanées, utiles aux praticiens notamment.
