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.

Rarity types among plant species with high conservation priority in Switzerland

We investigated the ecogeographic characteristics of 118 Swiss plant species listed as those deserving highest conservation priority in a national conservation guide and classified them into the seven Rabinowitz' rarity types, taking geographic distribution, habitat rarity and local population size into account. Our analysis revealed that species with high conservation priority in Switzerland mostly have a very restricted geographic distribution in Switzerland and generally occur in rare habitats, but do not necessarily constitute small populations and are generally not endemics on a global scale. Moreover, species that are geographically very restricted on a regional scale are not generally restricted on a global scale. By analysing relationships between rarity and IUCN extinction risks for Switzerland, we demonstrated that species with the highest risk of extinction are those with the most restricted geographic distribution; whereas species with lower risk of extinction (but still high conservation priority) include many regional endemics. Habitat rarity and local population size appeared to be of minor importance for the assessment of extinction risk in Switzerland, but the total number of fulfilled rarity criteria still correlated positively with the severity of extinction risk. Our classification is the first preliminary assessment of the relative importance of each rarity type among endangered plant species of the Swiss flora and our results underline the need to distinguish between a regional and a global responsibility for the conservation of rare and endangered species.

Predicting potential distribution of the jaguar (Panthera onca) in Mexico: identification of priority areas for conservation

Aim The jaguar, Panthera onca, is a species of global conservation concern. In Mexico, the northernmost part of its distribution range, its conservation status, is particularly critical, while its potential and actual distribution is poorly known. We propose an ensemble model (EM) of the potential distribution for the jaguar in Mexico and identify the priority areas for conservation.Location Mexico.Methods We generated our EM based on three presence-only methods (Ecological Niche Factor Analysis, Mahalanobis distance, Maxent) and considering environmental, biological and anthropogenic factors. We used this model to evaluate the efficacy of the existing Mexican protected areas (PAs), to evaluate the adequacy of the jaguar conservation units (JCUs) and to propose new areas that should be considered for conservation and management of the species in Mexico.Results Our results outline that 16% of Mexico (c. 312,000 km2) can be considered as suitable for the presence of the jaguar. Furthermore, 13% of the suitable areas are included in existing PAs and 14% are included in JCUs (Sanderson et al., 2002).Main conclusions Clearly much more should be carried out to establish a proactive conservation strategy. Based on our results, we propose here new jaguar conservation and management areas that are important for a nationwide conservation blueprint.

Le sens des messages préventifs du sida: consensus et dissensions au sien de la population générale

La recherche « Le sens des messages préventifs du sida » a été dirigée par une équipe de spécialistes relevant de domaines distincts - linguistique (Pr Pascal Singy), santé publique (Dre Brenda Spencer), médecine psychosociale (Pr Patrice Guex). Partant du constat que les langues naturelles n'existent que sous la forme de variétés, il a été postulé que le registre lexical du VIH/sida et de sa prévention n'échappe pas au principe de variabilité sémantique qui veut que, séparés par la multiplicité de leurs identités (sexe, appartenance socioculturelle, âge, etc.), les membres d'une « même » communauté linguistique tendent à associer à une unité lexicale donnée des significations différentes, voire antagonistes. Menée entre 2004 et 2006 en Suisse romande, la recherche « Le sens des messages préventifs du sida » s'appuie sur une approche sémantique de la prévention. Elle interroge les limites d'une communication préventive différée - par voie d'affiches et de brochures, en particulier - qui suppose que le destinataire ou récepteur d'un message en prend connaissance en l'absence de celui qui l'a émis. Les différents mécanismes conversationnels d'ajustement faisant à l'évidence défaut dans ce type de situation de communication, la variabilité sémantique peut dès lors apparaître problématique. S'agissant de l'objectif de cette recherche, il a essentiellement tenu dans la mise en évidence du degré de consensus que montrent les récepteurs (la population générale) ainsi que les émetteurs des messages préventifs à propos des significations attachées à des unités constitutives du lexique du VIH/sida et de sa prévention. Cette mise en évidence a par ailleurs permis d'évaluer la convergence des résultats obtenus pour les premiers et pour les seconds. Du point de vue méthodologique, un corpus de documents préventifs a été constitué - des brochures, principalement, publiées en français entre 1996 et 2004 - et analysé. Soixante et une unités lexicales, relevant du français commun ou spécialisé, ont alors été sélectionnées. L'ensemble de ces unités a été soumis à soixante représentants de la population générale vaudoise ainsi qu'à trente professionnels vaudois de la prévention dans le cadre d'entretiens en face à face. Ces entretiens ont permis de dégager les significations que ces deux populations attachent à une partie des unités lexicales (N=21) et le niveau d'intelligibilité/utilisation de l' autre partie des unités (N=40) - cf. infra *. Sur la base des résultats obtenus pour la population générale vaudoise, quinze unités lexicales apparues particulièrement problématiques ont été sélectionnées et soumises par le moyen d'une enquête téléphonique (CATI) à cinq cents Romands. Mêlant techniques qualitatives et quantitatives, la recherche « Le sens des messages préventifs du sida » apporte des résultats intéressant non plus seulement les agents de la prévention du VIH/sida, mais également les patients de celle-ci, c'est-à-dire la population générale. Des résultats qui se trouvent susceptibles de renforcer la portée de la prévention du VIH/sida en particulier dans la partie francophone de la Suisse. *Les unités lexicales sélectionnées sont les suivantes : abstinence, anus, caresses, coït anal, contact sexuel, contamination par voie sexuelle, coucher avec, cunnilingus, dépistage, « évitez le contact de la bouche avec du sperme ou du sang », faire l'amour, fellation, fidèle, gai, gay, immunisé, infection sexuellement transmissible, IST, liquides biologiques, maladies vénériennes, menstruation, MST, muqueuses, muqueuse buccale, muqueuses génitales, « pas de sperme dans la bouche », pathogène, pénétration, plaie ouverte, préservatif, préservatif féminin, prophylaxie de post-exposition [PEP], rapport bucco-génital, rapport sexuel, rapports sexuels non protégés, rapports sexuels oraux, rectum, relation anale, relation stable, relation vaginale, safer sex, sécrétions sexuelles, sécrétions vaginales, séronégatif, séropositif, sexe à moindre risque, sexe anal, sida, sperme, surcontamination, symptôme, système immunitaire, test d'anticorps VIH, test VIH, traitements antirétroviraux combinés, traitement combiné, trithérapies, urètre, vaginal, VIH, virus IH.

L'incontinence urinaire chez des personnes âgées hospitalisées en unité de gériatrie: est-ce vraiment une priorité pour les infirmières [Urinary incontinence in hospitalized geriatric patients : is it really a priority for nurses?].

INTRODUCTION: urinary incontinence (UI) is a phenomenon with high prevalence in hospitalized elderly patients, effecting up to 70% of patients requiring long term care. However, despite the discomfort it causes and its association with functional decline, it seems to be given insufficient attention by nurses in geriatric care. OBJECTIVES: to assess the prevalence of urinary incontinence in geriatric patients at admission and the level of nurse involvement as characterized by the explicit documentation of UI diagnosis in the patient's record, prescription of nursing intervention, or nursing actions related to UI. METHODS: cross-sectional retrospective chart review. One hundred cases were randomly selected from those patients 65 years or older admitted to the geriatric ward of a university hospital. The variables examined included: total and continence scores on the Measure of Functional Independence (MIF), socio-demographic variables, presence of a nursing diagnosis in the medical record, prescription of or documentation of a nursing intervention related to UI. RESULTS: the prevalence of urinary incontinence was 72 % and UI was positively correlated with a low MIF score, age and status of awaiting placement. Of the examined cases, nursing diagnosis of UI was only documented in 1.4 % of cases, nursing interventions were prescribed in 54 % of cases, and at least one nursing intervention was performed in 72 % of cases. The vast majority of the interventions were palliative. DISCUSSION: the results on the prevalence of IU are similar to those reported in several other studies. This is also the case in relation to nursing interventions. In this study, people with UI were given the same care regardless of their MIF score MIF, age or gender. One limitation of this study is that it is retrospective and therefore dependent on the quality of the nursing documentation. CONCLUSIONS: this study is novel because it examines UI in relation to nursing interventions. It demonstrates that despite a high prevalence of UI, the general level of concern for nurses remains relatively low. Individualized care is desirable and clinical innovations must be developed for primary and secondary prevention of UI during hospitalization.

'Steal me if you can!' The impact of campaign messages on associative issue ownership

Whereas extant work on issue ownership treats voters' issue ownership perceptions as independent variables to explain electoral choice or party behaviour, this article examines whether parties can, by communicating on an issue, turn voters' perceptions of issue ownership to their advantage. In contrast to most previous studies that have focused on competence ownership - measured as a party's capacity to handle an issue - this article analyses the short-term and long-term impact of campaign messages on voters' perceptions of associative ownership, which refers to the voters' spontaneous party-issue association, regardless of whether or not voters consider the party as the most competent at dealing with the issue at hand. Based on an online experimental design in Belgium, we show that parties are unable to steal issues that are associated with another party. However, by communicating on their own issues, parties can reinforce their reputation as an associative owner - but only in the short run and only if their previous ownership reputation is not overly strong.

Quelle adéquation entre les messages publicitaires sur les médicaments avec les évidences basées sur les preuves de l'EBM et les normes législatives

L'objectif de cette étude est d'évaluer l'adéquation des messages publicitaires sur les médicaments parus en 2007 dans quatre journaux destinés aux professionnels de la santé ("Praxis", "Forum médical suisse", "Bulletin des médecins suisses" et "Revue médicale suisse") avec les évidences basées sur les preuves de l'EBM et des normes législatives ainsi que de vérifier s'ils sont supportés par les références bibliographiques mentionnées. Méthode: les messages publicitaires des cinq grands groupes thérapeutiques (à savoir: anti-ostéoporotiques/arthrosiques, antidépresseurs, antihypertenseurs, AINS et hypolipémiants) sont évalués sur [ces] trois critères.

Prévention des alcoolisations aiguës a l'adolescence: quel rôle pour le médecin de famille [Prevention of binge drinking in adolescents: do family doctors have a role to play?].

Binge drinking has nearly become the norm for young people and is thus worrying. Although alcohol use in males attracts more media attention, females are also frequently affected. A variety of preventive measures can be proposed: at the individual level by parents, peers and family doctors; at the school and community level, particularly to postpone age of first use and first episode of drunkenness; at the structural level through a policy restricting access to alcohol for young people and increasing its price. Family doctors can play an important role in identifying at risk users and individualising preventive messages to which these young people are exposed in other contexts.
