Analysis of patient physical restraints usage in a Swiss emergency service

Introduction: Emergency services (ES) are often faced with agitated,confused or aggressive patients. Such situations may require physicalrestraint. The prevalence of these measures is poorly documented,concerning 1 to 10% of patients admitted in the ES. The indications forrestraint, the context and the related complications are poorly studied.The emergency service and the security service of our hospital havedocumented physical restraint for several years, using specific protocolsintegrated into the medical records. The study evaluated the magnitudeof the problem, the patient characteristics, and degree of adherence tothe restraint protocol.Methods: Retrospective study of physical restraint used on adultpatients in the ES in 2009. The study included analysis of medical anddemographic characteristics, indications justifying restraint and qualityof restraint documentation. Patients were identified from computerizedES and security service records. The data were supplemented byexamination of patients' medical records.Results: In 2009, according to the security service, 390 patients (1%)were physically restrained in the ES. The ES computerized systemidentified only 196 patients. Most patients were male (62%). The medianage was 40 years (15-98 years; P90 = 80 years). 63 % of the situationsoccurred between 18h00 and 6h00, and most frequently on Saturday(19%). Substance or alcohol abuse was present in 48.7% of cases andacute psychiatric crisis was mentioned in 16.7%. In most cases,restraint was motivated by extreme agitation or auto / hetero-aggressiveviolence. Most patients (68 %) were restrained with upper limb andabdominal restraints. More than three anatomic restraints werenecessary in 52 % of the patients. Intervention of security guards wasrequired in 77% of the cases. 61 restraint protocols (31 %) were missingand 57% of the records were incomplete. In many cases, the protocolsdid not include the signature of the physician (22%) or of the nurse(43.8%). Medical records analysis did not allow reliable estimation ofthe number of restraint-induced complications.Conclusions: Physical restraint is most often motivated by majoragitation and/or secondary to substance abuse. Caregivers regularlycall security guards for help. Restraint documentation is often missing orincomplete, requiring major improvement in education and prescription.

Bone microarchitecture assessed by TBS predicts osteoporotic fractures independent of bone density: The manitoba study.

The measurement of BMD by dual-energy X-ray absorptiometry (DXA) is the "gold standard" for diagnosing osteoporosis but does not directly reflect deterioration in bone microarchitecture. The trabecular bone score (TBS), a novel gray-level texture measurement that can be extracted from DXA images, correlates with 3D parameters of bone microarchitecture. Our aim was to evaluate the ability of lumbar spine TBS to predict future clinical osteoporotic fractures. A total of 29,407 women 50 years of age or older at the time of baseline hip and spine DXA were identified from a database containing all clinical results for the Province of Manitoba, Canada. Health service records were assessed for the incidence of nontraumatic osteoporotic fracture codes subsequent to BMD testing (mean follow-up 4.7 years). Lumbar spine TBS was derived for each spine DXA examination blinded to clinical parameters and outcomes. Osteoporotic fractures were identified in 1668 (5.7%) women, including 439 (1.5%) spine and 293 (1.0%) hip fractures. Significantly lower spine TBS and BMD were identified in women with major osteoporotic, spine, and hip fractures (all p < 0.0001). Spine TBS and BMD predicted fractures equally well, and the combination was superior to either measurement alone (p < 0.001). Spine TBS predicts osteoporotic fractures and provides information that is independent of spine and hip BMD. Combining the TBS trabecular texture index with BMD incrementally improves fracture prediction in postmenopausal women. © 2011 American Society for Bone and Mineral Research.

TBS (trabecular bone score) and diabetes-related fracture risk.

CONTEXT: Type 2 diabetes is associated with increased fracture risk but paradoxically greater bone mineral density (BMD). Trabecular bone score (TBS) is derived from the texture of the spine dual x-ray absorptiometry (DXA) image and is related to bone microarchitecture and fracture risk, providing information independent of BMD. OBJECTIVE: This study evaluated the ability of lumbar spine TBS to account for increased fracture risk in diabetes. DESIGN AND SETTING: We performed a retrospective cohort study using BMD results from a large clinical registry for the province of Manitoba, Canada. Patients: We included 29,407 women 50 years old and older with baseline DXA examinations, among whom 2356 had diagnosed diabetes. MAIN OUTCOME MEASURES: Lumbar spine TBS was derived for each spine DXA examination blinded to clinical parameters and outcomes. Health service records were assessed for incident nontraumatic major osteoporotic fractures (mean follow-up 4.7 years). RESULTS: Diabetes was associated with higher BMD at all sites but lower lumbar spine TBS in unadjusted and adjusted models (all P < .001). The adjusted odds ratio (aOR) for a measurement in the lowest vs the highest tertile was less than 1 for BMD (all P < .001) but was increased for lumbar spine TBS [aOR 2.61, 95% confidence interval (CI) 2.30-2.97]. Major osteoporotic fractures were identified in 175 women (7.4%) with and 1493 (5.5%) without diabetes (P < .001). Lumbar spine TBS was a BMD-independent predictor of fracture and predicted fractures in those with diabetes (adjusted hazard ratio 1.27, 95% CI 1.10-1.46) and without diabetes (hazard ratio 1.31, 95% CI 1.24-1.38). The effect of diabetes on fracture was reduced when lumbar spine TBS was added to a prediction model but was paradoxically increased from adding BMD measurements. CONCLUSIONS: Lumbar spine TBS predicts osteoporotic fractures in those with diabetes, and captures a larger portion of the diabetes-associated fracture risk than BMD.

Spine bone texture assessed by trabecular bone score (TBS) predicts osteoporotic fractures in men: The Manitoba Bone Density Program.

INTRODUCTION: One quarter of osteoporotic fractures occur in men. TBS, a gray-level measurement derived from lumbar spine DXA image texture, is related to microarchitecture and fracture risk independently of BMD. Previous studies reported the ability of spine TBS to predict osteoporotic fractures in women. Our aim was to evaluate the ability of TBS to predict clinical osteoporotic fractures in men. METHODS: 3620 men aged ≥50 (mean 67.6years) at the time of baseline DXA (femoral neck, spine) were identified from a database (Province of Manitoba, Canada). Health service records were assessed for the presence of non-traumatic osteoporotic fracture after BMD testing. Lumbar spine TBS was derived from spine DXA blinded to clinical parameters and outcomes. We used Cox proportional hazard regression to analyze time to first fracture adjusted for clinical risk factors (FRAX without BMD), osteoporosis treatment and BMD (hip or spine). RESULTS: Mean followup was 4.5years. 183 (5.1%) men sustain major osteoporotic fractures (MOF), 91 (2.5%) clinical vertebral fractures (CVF), and 46 (1.3%) hip fractures (HF). Correlation between spine BMD and spine TBS was modest (r=0.31), less than correlation between spine and hip BMD (r=0.63). Significantly lower spine TBS were found in fracture versus non-fracture men for MOF (p<0.001), HF (p<0.001) and CVF (p=0.003). Area under the receiver operating characteristic curve (AUC) for incident fracture discrimination with TBS was significantly better than chance (MOF AUC=0.59, p<0.001; HF AUC=0.67, p<0.001; CVF AUC=0.57, p=0.032). TBS predicted MOF and HF (but not CVF) in models adjusted for FRAX without BMD and osteoporosis treatment. TBS remained a predictor of HF (but not MOF) after further adjustment for hip BMD or spine BMD. CONCLUSION: We observed that spine TBS predicted MOF and HF independently of the clinical FRAX score, HF independently of FRAX and BMD in men. Studies with more incident fractures are needed to confirm these findings.

TBS (Trabecular Bone Score) is More Sensitive Than BMD to Diabetes-Related Fracture Risk

Background:Type 2 diabetes (T2D) is associated with increased fracture risk but paradoxically greater BMD. TBS (trabecular bone score), a novel grey-level texture measurement extracted from DXA images, correlates with 3D parameters of bone micro-architecture. We evaluated the ability of lumbar spine (LS) TBS to account for the increased fracture risk in diabetes. Methods:29,407 women ≥50 years at the time of baseline hip and spine DXA were identified from a database containing all clinical BMD results for the Province of Manitoba, Canada. 2,356 of the women satisfied a well-validated definition for diabetes, the vast majority of whom (>90%) would have T2D. LS L14 TBS was derived for each spine DXA examination blinded to clinical parameters and outcomes. Health service records were assessed for incident non-traumatic major osteoporotic fracture codes (mean follow-up 4.7 years). Results:In linear regression adjusted for FRAX risk factors (age,BMI, glucocorticoids, prior major fracture, rheumatoid arthritis, COPD as a smoking proxy, alcohol abuse) and osteoporosis therapy, diabetes was associated with higher BMD for LS, femoral neck and total hip but lower LS TBS (all p<0.001). Similar results were seen after excluding obese subjects withBMI>30. In logistic regression (Figure), the adjusted odds ratio (OR) for a skeletal measurement in the lowest vs highest tertile was less than 1 for all BMD measurements but increased for LS TBS (adjusted OR 2.61, 95%CI 2.30-2.97). Major osteoporotic fractures were identified in 175 (7.4%) with and 1,493 (5.5%) without diabetes (p < 0.001). LS TBS predicted fractures in those with diabetes (adjusted HR 1.27, 95%CI 1.10-1.46) and without diabetes (HR 1.31, 95%CI 1.24-1.38). LS TBS was an independent predictor of fracture (p<0.05) when further adjusted for BMD (LS, femoral neck or total hip). The explanatory effect of diabetes in the fracture prediction model was greatly reduced when LS TBS was added to the model (indicating that TBS captured a large portion of the diabetes-associated risk), but was paradoxically increased from adding any of the BMD measurements. Conclusions:Lumbar spine TBS is sensitive to skeletal deterioration in postmenopausal women with diabetes, whereas BMD is paradoxically greater. LS TBS predicts osteoporotic fractures in those with diabetes, and captures a large portion of the diabetes-associated fracture risk. Combining LS TBS with BMD incrementally improves fracture prediction.

Epidemiology and injury patterns of patients consulting following assault by nightclub security agents in a university hospital emergency service and an associated specialised forensic consultation

Introduction: The Violence Medical Unit (VMU), a specialised forensic medical consultation, was created at the Lausanne university Hospital in 2006. All patients consulting at the ED for interpersonal violencerelated injury are referred to the VMU, which provides forensic documentation of the injury and referral to the relevant community based victim-support organisations within 48 hours of the ED visit. This frees the ED medical staff from forensic injury documentation and legal/social referral, tasks for which they lack both time and training. Among community violence, assaults by nightclub security agents against patrons have increased from 6% to 10% between 2007 and 2009. We set out to characterise the demographics, assault mechanisms, subsequent injuries, prior alcohol intake and ED & VMU costs incurred by this group of patients. Methods: We retrospectively included all patients consulting at the VMU due to assault by nightclub security agents from January 2007 to December 2009. Data was obtained from ED & VMU medical, nursing and administrative records. Results: Our sample included 70 patients, of which 64 were referred by the CHUV ED. The victims were typically young (median age 29) males (93%). 77% of assaults occurred on the weekend between 12 PM and 4 AM, and 73% of the victims were under the influence of alcohol. 83% of the patients were punched, kicked and/or head-butted; 9% had been struck with a blunt instrument. 80% of the injuries were in the head and neck area and 19% of the victims sustained fractures. 21% of the victims were prescribed medical leave. Total ED & VMU costs averaged 1048 SFr. Conclusion: Medical staff treating this population of assault victims must be aware of the assault mechanisms and injury patterns, in particular the high probability of fractures, in order to provide adequate diagnosis and care. Associated inebriation mandates liberal use of radiology, as delayed or missed diagnosis may have medical, medicolegal and legal implications. Emergency medical services play an important role in detecting and reporting of such incidents. Centralised management of the forensic documentation facilitates referral to victim support organisations and epidemiological data collection. Magnitudes and trends of the different types of violence can be determined, and this information can be then impact public safety management policies.

Internet au service du patrimoine. Cartographie dynamique de l'inventaire des géotopes d'importance nationale

L'inventaire des géotopes d'importance nationale, aujourd'hui proche de son état final, est le fruit d'un long travail de sélection, de documentation ainsi que de définition et de numérisation des périmètres des sites initié dans les années 1990 par le groupe de travail pour la protection des géotopes en Suisse (Strasser et al. 1995, Berger et al. 2008). Il représente un outil au service de la diffusion et à la promotion du géopatrimoine suisse, auprès de la population en général et des professionnels des géosciences en particulier, dans un but de valorisation patrimoniale et de protection et par une sensibilisation à la valeur particulière et à la vulnérabilité des géotopes.¦C'est dans cet objectif qu'a été développée une interface cartographique rendant accessible sur Internet le contenu de cet inventaire. L'outil de web mapping utilisé - GoogleMaps API - permet en effet d'enrichir une interface de navigation intuitive de diverses fonctions additionnelles offertes par la cartographie sur internet (Kraak 2004, Plewe 2007). La carte n'est donc pas seulement une représentation de la réalité permettant la localisation de différents objets, mais également un outil de recherche thématique et spatiale ainsi qu'un index reliant chaque objet cartographié à diverses informations.¦Porte d'accès aux données des site à une échelle individuelle ou globale, mais aussi outil d'exploration, cette interface propose plusieurs niveaux d'utilisation, correspondant aux diverses interactions possibles avec ces données : naviguer et découvrir les sites, réaliser des sélections multiples, comparer les géotopes à d'autres données, comme l'inventaire fédéral des paysages. L'utilisateur peut ainsi produire à chaque fois la carte qui répond à ses besoins et à ses questions. En donnant à tous accès au contexte et aux particularités de chaque site par delà la globalité abstraite de l'inventaire, cette application se veut avant tout un outil au service de la médiation du géopatrimoine.

Le suicide comme langage de l'oppression. Ethnographie d'un service d'urgences psychiatriques

Ce travail s'intéresse à la problématique du suicide à partir de l'émergence en Suisse, vers la fin des années '90, de la prévention du suicide comme préoccupation sociale et politique. Au début, ce sont les milieux associatifs qui ont soulevé à cette question en percevant le suicide comme le reflet d'une souffrance d'origine sociale. Par la suite, la prévention du suicide est progressivement devenue une problématique de santé publique appréhendée essentiellement sous le registre médical comme étant le symptôme d'une pathologie psychiatrique. Après une première partie consacrée aux processus sociopolitiques et aux transformations morales touchant le suicide et sa prévention, ce travail approfondit, au travers d'un terrain ethnographique, la prise en charge des personnes présentant des problématiques suicidaires au sein d'un service d'urgences psychiatriques.Malgré une approche se voulant biopsychosociale, l'analyse des discours et des pratiques soignantes montre que la dimension sociale est largement négligée, conduisant à une médicalisation de situations de détresse qui sont principalement de nature sociale. En effet, parmi la population qui fréquente le service, on observe une surreprésentation de personnes issues des classes sociales défavorisées présentant souvent des trajectoires biographiques particulièrement difficiles. Au fil des entretiens avec les patients émerge une analyse voyant la souffrance psychique et la prise en charge psychiatrique comme étant aujourd'hui une manière d'obtenir une reconnaissance sociale et symbolique. Les problématiques suicidaires peuvent ainsi être interprétées comme une forme d'expression, un langage au travers duquel s'exprime la position sociale défavorisée.En adoptant une posture militante construite à partir de la réalité ethnographique, les problématiques suicidaires sont analysées comme l'expression d'une condition d'oppression liée à un cadre social et économique de plus en plus contraignant, à des rapports de pouvoir inégaux ainsi qu'à une lecture individualisante, médicalisante et pathologisante des problèmes sociaux.The present thesis discusses suicide prevention in Switzerland, which emerged as a social and political issue at the end of the '90s. At first, this question was taken up by associations considering suicide as a reflection of social suffering. Thereafter, suicide prevention gradually became a public health matter conceived with a medical approach as a symptom of a psychiatric disease. The first part of this work analyzes the sociopolitical process and moral transformations concerning suicide and its prevention. The second part is based on an ethnographic fieldwork conducted in a psychiatric emergency unit that attends people who have tried to attempt their life or consider doing it. Through the analysis of discourses and practices of the medical staff, this research shows that the social aspect of suicide is widely neglected, leading to a medicalization of social problems. In fact, amongst patients attending the emergency unit, there is an over-­-representation of people from disadvantaged classes having very difficult life stories. Interviews with patients also revealed that psychic suffering and psychiatric treatment is nowadays a way to get social and symbolical recognition. Suicidal problems can be understood as a language expressing a disadvantaged social position. By adopting a militant position constructed from the ethnographic reality, suicide is analyzed as the expression of an oppressed condition related to a more and more restricted social and economic situation, to unequal power relations as well as to an individualistic, medical and pathological interpretation of social problems.

Un groupe d'accueil pour la fratrie lors d'une naissance à risque dans un service de néonatalogie

Cet article a pour objectif de décrire l'expérience d'un groupe d'accueil pour les frères et soeurs d'enfants hospitalisés en néonatoloyie. Cet événement représente un facteur de stress et suscite d'importantes angoisses chez les parents. Sensibles et perméables au vécu parental, les frères et soeurs peuvent éprouver une difficulté à se représenter ce qui se déroule autour d'eux. Leur offrir un lieu de parole avec leurs parents se révèle important et permet de préparer la rencontre avec le nouveau-né hospitalisé. Il s'agit d'un espace permettant de nouvelles représentations du bébé, pour la fratrie et pour les parents.

Prise en charge par une équipe pluridisciplinaire des patients avec multiples vulnérabilités dans un service d'urgence

Introduction: Les centres d'urgence se trouvent régulièrement confrontés à des patients avec de multiples vulnérabilités médico-sociales qui recourent préférentiellement aux urgences pour y recevoir des soins de bases. Leurs fréquentes consultations contribuent à encombrer les urgences : dans notre service d'urgence entre avril 2008 et mars 2009, une étude ayant pour but de caractériser ces patients a montré que 14 % de l'ensemble des consultations ont été causées par 5 % des patients admis > 4 x/an.Matériel et méthode: Cohorte prospective des patients admis aux urgences et présentant des critères touchant > 3 axes de vulnérabilités sur les 5 axes reconnus habituellement (déterminants somatiques, de santé mentale, comportemental, social, de consommation de soins). Les patients inclus ont été soit signalés par le personnel médico-infirmier des urgences, soit dépistés par une équipe pluridisciplinaire (2 infirmières, 1 assistant social, 1 médecin) durant les jours ouvrables du 1.9.2010 au 14.12.2010.Résultats: 75 patients ont été inclus (65 % d'hommes). La moyenne d'âge était de 43 ans. 59 % étaient des migrants en provenance de : Europe (22 %), Afrique (22 %), Asie (12 %), Amériques du Sud (6 %) et du Nord (1 %). Les vulnérabilités les plus fréquentes étaient: somatiques 76 % (maladies aiguës/chroniques sévères 50 %, mauvaise adhérence thérapeutique 40 %), liées à la santé mentale 65 % (troubles anxieux et dépressifs 54 %), comportementales 80 % (addictions aux substances 73 %), sociales 93 % (absence de domicile fixe 31 %, absence d'assurance-maladie 15 %, barrières linguistiques 24 %, à l'assistance sociale 46 %) et consommation de soins (> 4 visites aux urgences/an 57 %, absence de médecin de premier recours 33 %). La charge de travail moyenne pour orienter ces patients vers des structures de santé primaire était de 3 heures/cas. Les interventions ont été d'évaluer le réseau de soins déjà impliqué (98 %), de réorienter dans le réseau ambulatoire (64 %) ou vers les services sociaux (37 %).Conclusion: Les vulnérabilités multiples sont relativement peu fréquentes dans notre service d'urgence mais leur complexité requiert des ressources qui dépassent ce que peuvent offrir des équipes de soins habituelles aux urgences. Une prise en charge individuelle par une équipe pluridisciplinaire est susceptible de fournir ces ressources et de réorienter ces patients vers des structures ambulatoires adaptées à leurs besoins.

General Practitioners' willingness to pay for continuing medical education in a fee-for-service universal coverage health care system

Background: Sponsoring of physicians meetings by life science companies has led to reduced participation fees but might influence physician's prescription practices. A ban on such sponsoring may increase participation fees. We aimed to evaluate factors associated with physicians' willingness to pay for medical meetings, their position on the sponsoring of medical meetings and their opinion on alternative financing options. Methods: An anonymous web-based questionnaire was sent to 447 general practitioners in one state in Switzerland, identified through their affiliation to a medical association. The questionnaire evaluated physicians' willingness to pay for medical meetings, their perception of a bias in prescription practices induced by commercial support, their opinion on the introduction of a binding legislation and alternative financing options, their frequency of exchange with sales representatives and other relevant socioeconomic factors. We built a multivariate predictor logistic regression model to identify determinants of willingness to pay. Results: Of the 115 physicians who responded (response rate 26%), 48% were willing to pay more than what they currently pay for congresses, 79% disagreed that commercial support introduced a bias in their prescription practices and 61% disagreed that it introduced a bias in their colleagues' prescription practices. Based on the multivariate logistic regression, perception of a bias in peers prescription practices (OR=7.47, 95% CI 1.65-38.18) and group practice structure (OR=4.62, 95% CI 1.34-22.29) were significantly associated with an increase in willingness to pay. Two thirds (76%) of physicians did not support the introduction of a binding legislation and 53% were in favour of creating a general fund administered by an independent body. Conclusion: Our results suggest that almost half of physicians surveyed are willing to pay more than what they currently pay for congresses. Predictors of an increase in physicians' willingness to pay were perception of the influence of bias in peers prescription practices and group practice structure. Most responders did not agree that sponsoring introduced prescribing bias nor did they support the 2 introduction of a binding legislation prohibiting sponsoring but a majority did agree to an independent body that would centrally administer a general fund.
