Les centrales 144: ressources à disposition des médecins de premier recours lors de réanimation?

Introduction: Les médecins de premiers recours sont confrontés en moyenne une fois dans leur carrière à un arrêt cardio-respiratoire (ACR), dans leur cabinet médical ou lors d'une activité de garde. La majorité d'entre eux ont pratiqué des réanimations lors de leurs années de formations hospitalières. L'actualisation des pratiques et le maintien des compétences et d'une certaine aisance restent néanmoins difficiles, malgré la mise à disposition de formations théoriques et pratiques.Nouveaux apports des centrales 144: Le développement du numéro 144 et des urgences pré-hospitalières permet d'envisager de nouvelles collaborations entre les centrales 144 et les médecins de premier recours, en particulier pour ces situations exceptionnelles de réanimation. Depuis peu, les régulateurs du 144 sont en effet compétents pour aider les témoins laïcs ou les professionnels de la santé, à effectuer les premiers gestes de réanimation, en attendant l'arrivée d'une ambulance.Résultats actuels: Dès 2008, la Centrale 144 Vaud a systématisé la réanimation par téléphone (T-CPR), de même que les conseils à donner aux témoins, par exemple lors de crise convulsive ou lors d'hémorragie. Au cours des 12 premiers mois d'application, la Centrale 144 Vaud a reçu 497 appels pour des ACR. 203 cas ont été exclus (appelant à distance du patient, témoin trop agité, mort évidente, patient en fin de vie). 294 cas étaient éligibles pour bénéficier d'une T-CPR. Une réanimation a pu être proposée à 202 reprises (68.7 %). Dans les autres cas (92), le régulateur n'a pas réussi au vu des informations à disposition à identifier un ACR lors de l'appel. Le devenir des patients ayant bénéficié de T-CPR est en cours d'analyse.Conclusion: Les régulateurs sanitaires des centrales 144 suisses devraient aujourd'hui tous être capables de proposer une réanimation par téléphone. Ils constituent avec les éventuels témoins de l'ACR et les médecins de premier recours, un maillon essentiel de la chaîne des secours. Dès l'appel, ils sont à la disposition des appelants profanes, aussi bien que des médecins de premier recours, pour soutenir l'initiation des gestes de réanimation, dans des situations d'urgence bien souvent génératrice d'anxiété et de stress.

La réhabilitation psychosociale a l'aube du XXIème siècle. I: Principes, population cible et pathologie en cause

The relatively recent development of the psychosocial rehabilitation has its origins mainly in the progress of modern psychopharmacology, the assertion of the rights of the patients and the result of the studies showing that the evolution of persons suffering from severe and persistent mental illnesses can prove to be positive in many cases. In spite of the heterogeneity of the experiences and of the theoretical references, the core principles of the psychosocial rehabilitation imposed themselves. These principles can be classified according to three levels, that of relational ethics, that of the method of intervention and that of the institutional device. A recent study showed that 2.4@1000 of the general adult population of the Canton of Vaud live in sociotherapeutic and rehabilitation accommodations. In this sample, there is a important percentage of relatively young persons (55.3% are under 40). In institutional accommodation there is a majority of patients suffering from major personality disorders and addiction (40.6%), followed by psychotic disorders (37.2%), persistent mood disorders (12.3%), neurotic disorders (6.6%) and psycho-organic disorders (3.3%). In home based rehabilitation, the ratio of patients with psychotic disorders is more important (53.1%). This difference would indicate that people with schizophrenia would have a better social outcome than personality disorders with addiction

Sondage pilote concernant la fréquentation d'une unité mobile de mammographie

En matière de dépistage du cancer du sein, il a été proposé de compléter les moyens techniques actuellement disponibles des praticiens du canton de Vaud par ceux d'une unité mobile de mammographie. Avant de se lancer dans cette aventure, il paraît raisonnable d'estimer le volume et la nature de la demande pour ce nouveau service. La participation des femmes vaudoises peut être évaluée par une enquête de population. Pour préparer cette enquête, un sondage téléphonique pilote a été effectué, permettant d'en estimer la faisabilité, le coût et le rendement.

Un regard sur la politique forestière suisse (essai)

In the form of an essay, the author proposes a review of the reasons behind the recent changes in forestry policy. He identifies two explanatory elements and goes into these in more detail: the loss in cohesion in sectorial forestry logic since the 1980s, and the internal division which has arisen on account of the failure to put through the partial revision of the Federal Forestry Law. Firstly, it is clear that forestry practice continues to function on a sectorial basis, even though the management of resources increasingly extends between sectors. Accordingly, he also sees forestry management as being restricted by exterior influences. Secondly, the dichotomy between production and protection weakens the forestry community. The author hopes forestry will be able to overcome these problems and thus become (once more) an influential political protagonist.

Introducing systematic dispatcher-assisted cardiopulmonary resuscitation (telephone-CPR) in a non-Advanced Medical Priority Dispatch System (AMPDS): implementation process and costs.

OBJECTIVE: In order to improve the quality of our Emergency Medical Services (EMS), to raise bystander cardiopulmonary resuscitation rates and thereby meet what is becoming a universal standard in terms of quality of emergency services, we decided to implement systematic dispatcher-assisted or telephone-CPR (T-CPR) in our medical dispatch center, a non-Advanced Medical Priority Dispatch System. The aim of this article is to describe the implementation process, costs and results following the introduction of this new "quality" procedure. METHODS: This was a prospective study. Over an 8-week period, our EMS dispatchers were given new procedures to provide T-CPR. We then collected data on all non-traumatic cardiac arrests within our state (Vaud, Switzerland) for the following 12months. For each event, the dispatchers had to record in writing the reason they either ruled out cardiac arrest (CA) or did not propose T-CPR in the event they did suspect CA. All emergency call recordings were reviewed by the medical director of the EMS. The analysis of the recordings and the dispatchers' written explanations were then compared. RESULTS: During the 12-month study period, a total of 497 patients (both adults and children) were identified as having a non-traumatic cardiac arrest. Out of this total, 203 cases were excluded and 294 cases were eligible for T-CPR. Out of these eligible cases, dispatchers proposed T-CPR on 202 occasions (or 69% of eligible cases). They also erroneously proposed T-CPR on 17 occasions when a CA was wrongly identified (false positive). This represents 7.8% of all T-CPR. No costs were incurred to implement our study protocol and procedures. CONCLUSIONS: This study demonstrates it is possible, using a brief campaign of sensitization but without any specific training, to implement systematic dispatcher-assisted cardiopulmonary resuscitation in a non-Advanced Medical Priority Dispatch System such as our EMS that had no prior experience with systematic T-CPR. The results in terms of T-CPR delivery rate and false positive are similar to those found in previous studies. We found our results satisfying the given short time frame of this study. Our results demonstrate that it is possible to improve the quality of emergency services at moderate or even no additional costs and this should be of interest to all EMS that do not presently benefit from using T-CPR procedures. EMS that currently do not offer T-CPR should consider implementing this technique as soon as possible, and we expect our experience may provide answers to those planning to incorporate T-CPR in their daily practice.

Breast cancer incidence in younger swiss women

Background Breast cancer in younger women has received increased attention in recent years. Although breast cancer is uncommon in young women, it is the most frequent cancer and the leading cause of cancer death for younger women in developed countries. For Switzerland, the United States and several European countries, declines in breast cancer incidence have been reported since around the year 2000, after decades of increase, among women aged 50 and older. On the other hand an increase in the incidence of breast cancer in younger women has been reported in recent years. Therefore, this study aims to evaluate time trends in breast cancer incidence in younger women in Switzerland. Methods Data on invasive breast cancer cases were obtained from the Swiss Cancer Registries of Basel, Fribourg, Geneva, Graubunden/Glarus, Jura, Neuchatel, St. Gallen-Appenzell, Ticino, Valais, Vaud and Zurich, covering the time period 1996 to 2009. Mid-year population estimates for the respective time period were supplied by the Swiss Federal Statistical Office. For females aged 20-49 years, annual age-standardized incidence rates (ASIRs) (European standard) per 100,000 person-years and corresponding 95%-confidence intervals (95% CI) were calculated. For females aged 20-39 and 40-49 years, ASIRs and incidence rate ratios (IRRs) were calculated by grouped time periods, consisting of 3-5 incidence years. IRRs and corresponding 95% CI were calculated using Poisson regression adjusting for age (reference period 1996-2000). Results ASIRs in females aged 20-49 increased gradually since 1996, being 57.36 per 100,000 person-years in 1996 (95% CI 52.54-62.51) and rising to 68.34 (95% CI 63.40-73.57) per 100,000 person-years in 2009. Comparing the time-period 2007-2009 and the reference period 1996-2000, IRRs show values of 1.17 (95% CI 1.04-1.31) for the age-group 20-39 years and 1.04 (95% CI 0.97-1.10) for the age-group 40-49 years. Conclusions Our findings confirm a slight increase in the incidence of invasive breast cancer in younger women in Switzerland during the period 1996-2009. An increase in breast cancer incidence in younger patients is an important public health problem. It warrants further investigations to identify specific risk factors of this population and to better understand the biology of this particular breast cancer.

Évaluation statistique des résultats des analyses ADN de 2005 à 2011 et recommandations stratégiques au sein de la section d'Identité judiciaire de la Police cantonale vaudoise

Notre étude a eu pour but d'analyser les résultats des analyses ADN effectuées sur les traces relevées sur des scènes de crimes ou sur des objets s'y apparentant. Cette analyse nous a permis d'en identifier les points forts et les points faibles. Les données concernant les résultats ADN des années 2005 à 2008 dans le canton de Vaud ont montré une augmentation significative du nombre de traces envoyées, avec en parallèle un déclin de la qualité des résultats. Suite à cette observation, des solutions ayant pour but de réduire le nombre de ces analyses négatives ont dû être adoptées. Des changements opérationnels ont alors été mis en place dès 2009. Il s'agissait alors, d'une part, d'agir au niveau des traces de contact en tenant compte du type de support sur lequel la trace était prélevée, et, d'autre part, d'agir sur les traces riches (sang, salive, sperme) en mettant en place l'analyse systématique de la nature de la trace à l'aide de tests indicatifs. L'évaluation des conséquences de la mise en place de ces procédures a été possible à l'aide d'une nouvelle analyse statistique. Les résultats montrent qu'un meilleur tri des traces permet une amélioration des résultats.

Convergences and divergences of diabetic patients' and healthcare professionals' opinions of care : a qualitative study

OBJECTIVES: To investigate opinions' convergences and divergences of diabetic patients and health-care professionals on diabetes care and the development of a regional diabetes programme. BACKGROUND: Development and implementation of a regional diabetes programme. RESEARCH DESIGN: Qualitative study using focus groups to elicit diabetic patients' and health-care professionals' opinions, followed by content analysis. SETTING AND PARTICIPANTS: Eight focus groups: four focus groups with diabetic patients (n = 39) and four focus groups with various health-care professionals (n = 34) residing or practicing in the canton of Vaud, Switzerland, respectively. RESULTS: Perceived quality of diabetes care varied between individuals and types of participants. To improve quality, patients favoured a comprehensive follow-up while professionals suggested considering existing structures and trained professionals. All participants mentioned communication difficulties between professionals and were favouring teamwork. In addition, they described the role that patients should have in care and self-management. Financial difficulties were also mentioned by both groups of participants. Finally, they were in favour of the development of a regional diabetes programme adapted to actors' needs. For patients indeed, such a programme would represent an opportunity to improve information and to have access to comprehensive care. For professionals, it would help the development of local networks and the reinforcement of existing tools and structures. DISCUSSION AND CONCLUSIONS: Acknowledging convergences and divergences of opinions of both diabetic patients and health-care professionals should help the further development of a programme adapted to users' needs, taking all stakeholders interests and priorities into consideration.

Impact and cost of a 2-week community-based screening and awareness program for diabetes and cardiovascular risk factors in a Swiss canton.

BACKGROUND: Community-based diabetes screening programs can help sensitize the population and identify new cases. However, the impact of such programs is rarely assessed in high-income countries, where concurrent health information and screening opportunities are common place. INTERVENTION AND METHODS: A 2-week screening and awareness campaign was organized as part of a new diabetes program in the canton of Vaud (population of 697,000) in Switzerland. Screening was performed without appointment in 190 out of 244 pharmacies in the canton at the subsidized cost of 10 Swiss Francs per participant. Screening included questions on risk behaviors, measurement of body mass index, blood pressure, blood cholesterol, random blood glucose (RBG), and A1c if RBG was >/=7.0 mmol/L. A mass media campaign promoting physical activity and a healthy diet was channeled through several media, eg, 165 spots on radio, billboards in 250 public places, flyers in 360 public transport vehicles, and a dozen articles in several newspapers. A telephone survey in a representative sample of the population of the canton was performed after the campaign to evaluate the program. RESULTS: A total of 4222 participants (0.76% of all persons aged >/=18 years) underwent the screening program (median age: 53 years, 63% females). Among participants not treated for diabetes, 3.7% had RBG >/= 7.8 mmol/L and 1.8% had both RBG >/= 7.0 mmol/L and A1c >/= 6.5. Untreated blood pressure >/=140/90 mmHg and/or untreated cholesterol >/=5.2 mmol/L were found in 50.5% of participants. One or several treated or untreated modifiable risk factors were found in 78% of participants. The telephone survey showed that 53% of all adults in the canton were sensitized by the campaign. Excluding fees paid by the participants, the program incurred a cost of CHF 330,600. CONCLUSION: A community-based screening program had low efficiency for detecting new cases of diabetes, but it identified large numbers of persons with elevated other cardiovascular risk factors. Our findings suggest the convenience of A1c for mass screening of diabetes, the usefulness of extending diabetes screening to other cardiovascular risk factors, and the importance of a robust background communication campaign.

Improving generalized regression analysis for the spatial prediction of forest communities

Aim This study used data from temperate forest communities to assess: (1) five different stepwise selection methods with generalized additive models, (2) the effect of weighting absences to ensure a prevalence of 0.5, (3) the effect of limiting absences beyond the environmental envelope defined by presences, (4) four different methods for incorporating spatial autocorrelation, and (5) the effect of integrating an interaction factor defined by a regression tree on the residuals of an initial environmental model. Location State of Vaud, western Switzerland. Methods Generalized additive models (GAMs) were fitted using the grasp package (generalized regression analysis and spatial predictions, http://www.cscf.ch/grasp). Results Model selection based on cross-validation appeared to be the best compromise between model stability and performance (parsimony) among the five methods tested. Weighting absences returned models that perform better than models fitted with the original sample prevalence. This appeared to be mainly due to the impact of very low prevalence values on evaluation statistics. Removing zeroes beyond the range of presences on main environmental gradients changed the set of selected predictors, and potentially their response curve shape. Moreover, removing zeroes slightly improved model performance and stability when compared with the baseline model on the same data set. Incorporating a spatial trend predictor improved model performance and stability significantly. Even better models were obtained when including local spatial autocorrelation. A novel approach to include interactions proved to be an efficient way to account for interactions between all predictors at once. Main conclusions Models and spatial predictions of 18 forest communities were significantly improved by using either: (1) cross-validation as a model selection method, (2) weighted absences, (3) limited absences, (4) predictors accounting for spatial autocorrelation, or (5) a factor variable accounting for interactions between all predictors. The final choice of model strategy should depend on the nature of the available data and the specific study aims. Statistical evaluation is useful in searching for the best modelling practice. However, one should not neglect to consider the shapes and interpretability of response curves, as well as the resulting spatial predictions in the final assessment.
