Efficacité a court et moyen termes des traitements d'urgence-crise pour couples et families: résultats et perspectives [Short and medium-term effectiveness of the emergency-crisis treatments for couples and families: results and perspectives].

From 2007 to 2010, the emergency-crisis unit of the Couple and Family Consultation Unit -UCCF (West Psychiatric Service, Prangins Psychiatric Hospital, Psychiatric Department of CHUV) has carried out a research about the relevance and usefulness of emergency-crisis, systemic-oriented treatments, for deeply distressed couples and families. Besides epidemiologic data, we present results demonstrating the efficiency of those treatments, both at short-term and at a one year's range. The global impact of such treatments in terms of public health, but also economical issues, make us believe that they should be fully included in the new trend of psychiatric ambulatory care, into the social net.

Consultation d'urgence/crise pour couples et families: motifs d'urgence et évaluation du traitement [Couples and families emergency/crisis consultation: emergency patterns and treatment assessment]

Since the opening in 2003 of the Couple & Family Consultation Unit (UCCF) at Prangins Hospital, we have met urgent demands and observed that the suffering systems (i.e., couples and families) couldn't face any waiting period. So in 2007 an Emergency/Crisis Facility was created, based on the hypothesis that there is no contra-indication to systemic emergency care, if one understands and structures both crisis and treatment. We studied the suffering population in demand and the emergency/crisis issues and assessed therapy efficiency. Then we observed that treating suffering systems in emergency does produce therapeutic gain in terms of crisis resolution and patients' satisfaction. Those treatments refer to public health issues, as considered the human, social and financial cost of couples/families dysfunctions.

Une équipe mobile en psychiatrie de l'âge avancé [A crisis team in the field of old age psychiatry]

In the context of demographic evolution, psychiatric care needs increase steadily in most western countries. Given the financial limitations, it is mandatory to establish appropriate care priorities in order to avoid psychiatric hospitalisations by assisting care providers, general practionners and nurses, at home or in the nursing homes. A crisis team has been established 18 months ago within the Division of old age psychiatry in Lausanne. The care program included immediate assistance in the community, assessement, crisis counseling, medication consultation and referral for psychiatric services providing an alternative to hospitalization. The first results indicate that this intervention is well accepted by the users and correspond to a real need.

Trends of pre-hospital emergency medical services activity over 10 years : a population-based registry analysis

BACKGROUND: The number of requests to pre-hospital emergency medical services (PEMS) has increased in Europe over the last 20 years, but epidemiology of PEMS interventions has little be investigated. The aim of this analysis was to describe time trends of PEMS activity in a region of western Switzerland. METHODS: Use of data routinely and prospectively collected for PEMS intervention in the Canton of Vaud, Switzerland, from 2001 to 2010. This Swiss Canton comprises approximately 10% of the whole Swiss population. RESULTS: We observed a 40% increase in the number of requests to PEMS between 2001 and 2010. The overall rate of requests was 35/1000 inhabitants for ambulance services and 10/1000 for medical interventions (SMUR), with the highest rate among people aged ≥ 80. Most frequent reasons for the intervention were related to medical problems, predominantly unconsciousness, chest pain respiratory distress, or cardiac arrest, whereas severe trauma interventions decreased over time. Overall, 89% were alive after 48 h. The survival rate after 48 h increased regularly for cardiac arrest or myocardial infarction. CONCLUSION: Routine prospective data collection of prehospital emergency interventions and monitoring of activity was feasible over time. The results we found add to the understanding of determinants of PEMS use and need to be considered to plan use of emergency health services in the near future. More comprehensive analysis of the quality of services and patient safety supported by indicators are also required, which might help to develop prehospital emergency services and new processes of care.

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.

Palliative care and prehospital emergency medicine: analysis of a case series.

Palliative care, which is intended to keep patients at home as long as possible, is increasingly proposed for patients who live at home, with their family, or in retirement homes. Although their condition is expected to have a lethal evolution, the patients-or more often their families or entourages-are sometimes confronted with sudden situations of respiratory distress, convulsions, hemorrhage, coma, anxiety, or pain. Prehospital emergency services are therefore often confronted with palliative care situations, situations in which medical teams are not skilled and therefore frequently feel awkward.We conducted a retrospective study about cases of palliative care situations that were managed by prehospital emergency physicians (EPs) over a period of 8 months in 2012, in the urban region of Lausanne in the State of Vaud, Switzerland.The prehospital EPs managed 1586 prehospital emergencies during the study period. We report 4 situations of respiratory distress or neurological disorders in advanced cancer patients, highlighting end-of-life and palliative care situations that may be encountered by prehospital emergency services.The similarity of the cases, the reasons leading to the involvement of prehospital EPs, and the ethical dilemma illustrated by these situations are discussed. These situations highlight the need for more formal education in palliative care for EPs and prehospital emergency teams, and the need to fully communicate the planning and implementation of palliative care with patients and patients' family members.

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.

Rapidly fatal poisoning with an insecticide containing rotenone.

Introduction: Rotenone is a botanical pesticide derived from extracts of Derris roots, which is traditionally used as piscicide, but also as an industrial insecticide for home gardens. Its mechanism of action is potent inhibition of mitochondrial respiratory chain by uncoupling oxidative phosphorylation by blocking electron transport at complex-I. Despite its classification as mild to moderately toxic to humans (estimated LD50, 300-500 mg/kg), there is a striking variety of acute toxicity of rotenone depending on the formulation (solvents). Human fatalities with rotenone-containing insecticides have been rarely reported, and a rapid deterioration within a few hours of the ingestion has been described previously in one case. Case report: A 49-year-old Tamil man with a history of asthma, ingested 250 mL of an insecticide containing 1.24% of rotenone (3.125 g, 52.1-62.5 mg/kg) in a suicide attempt at home. The product was not labeled as toxic. One hour later, he vomited repeatedly and emergency services were alerted. He was found unconscious with irregular respiration and was intubated. On arrival at the emergency department, he was comatose (GCS 3) with fixed and dilated pupils, and absent corneal reflexes. Physical examination revealed hemodynamic instability with hypotension (55/30 mmHg) and bradycardia (52 bpm). Significant laboratory findings were lactic acidosis (pH 6.97, lactate 17 mmol/L) and hypokalemia (2 mmol/L). Cranial computed tomography (CT) showed early cerebral edema. A single dose of activated charcoal was given. Intravenous hydration, ephedrine, repeated boli of dobutamine, and a perfusor with 90 micrograms/h norepinephine stabilized blood pressure temporarily. Atropine had a minimal effect on heart rate (58 bpm). Intravenous lipid emulsion was considered (log Pow 4.1), but there was a rapid deterioration with refractory hypotension and acute circulatory failure. The patient died 5h after ingestion of the insecticide. No autopsy was performed. Quantitative analysis of serum performed by high-resolution/accurate mass-mass spectrometry and liquid chromatography (LC-HR/AM-MS): 560 ng/mL rotenone. Other substances were excluded by gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS/MS). Conclusion: The clinical course was characterized by early severe symptoms and a rapidly fatal evolution, compatible with inhibition of mitochondrial energy supply. Although rotenone is classified as mild to moderately toxic, physicians must be aware that suicidal ingestion of emulsified concentrates may be rapidly fatal. (n=3): stridor, cyanosis, cough (one each). Local swelling after chewing or swallowing soap developed at the earliest after 20 minutes and persisted beyond 24 hours in some cases. Treatment with antihistamines and/or steroids relieved the symptoms in 9 cases. Conclusion: Bar soap ingestion by seniors carries a risk of severe local reactions. Half the patients developed symptoms, predominantly swellings of tongue and/or lips (38%). Cognitive impairment, particularly in the cases of dementia (37%), may increase the risk of unintentional ingestion. Chewing and intraoral retention of soap leads to prolonged contact with the mucosal membranes. Age-associated physiological changes of oral mucosa probably promote the irritant effects of the surfactants. Medical treatment with antihistamines and corticosteroids usually leads to rapid decline of symptoms. Without treatment, there may be a risk of airway obstruction.

Epidemiology and mortality of glacier crevasse accidents.

INTRODUCTION: Crevasse accidents can lead to severe injuries and even death, but little is known about their epidemiology and mortality. METHODS: We retrospectively reviewed helicopter-based emergency services rescue missions for crevasse victims in Switzerland between 2000 and 2010. Demographic and epidemiological data were collected. Injury severity was graded according to the National Advisory Committee for Aeronautics (NACA) score. RESULTS: A total of 415 victims of crevasse falls were included in the study. The mean victim age was 40 years (SD 13) (range 6-75), 84% were male, and 67% were foreigners. The absolute number of victims was much higher during the months of March, April, July, and August, amounting to 73% of all victims; 77% of victims were practicing mountaineering or ski touring. The mean depth of fall was 16.5m (SD 9.0) (range 1-35). Overall on-site mortality was 11%, and it was higher during the ski season than the ski offseason (14% vs. 7%; P=0.01), for foreigners (14% vs. 5%; P=0.01), and with higher mean depth of fall (22 vs. 15m; P=0.01). The NACA score was ≥4 for 22% of the victims, indicating potential or overt vital threatening injuries, but 24% of the victims were uninjured (NACA 0). Multivariable analyses revealed that depth of the fall, summer season, and snowshoeing were associated with higher NACA scores, whereas depth of the fall, snowshoeing, and foreigners but not season were associated with higher risk of death. CONCLUSION: The clinical spectrum of injuries sustained by the 415 patients in this study ranged from benign to life-threatening. Death occurred in 11% of victims and seems to be determined primarily by the depth of the fall.

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.

Concept de first responders en Suisse romande: état des lieux et perspectives [Concept of first responders in Western Switzerland: current situation and future perspectives].

The notion of "First Responder" (FR) refers to the system of first-aid volunteers who act to initiate the first-aid care before the classical emergency help arrives. In 2011, the French-speaking Switzerland counts 19 groups, divided up between four cantons (Fribourg, Vaud, Neuchâtel, Valais). The geographical distribution of those FR shows the stakes of these peripherical areas, with the accessibility difficulties for the emergency services, and a low demography of ambulances and doctors. The number of interventions carried out by the FR has significantly increased during the last years. The association of a quality formation, an excellent knowledge of the ground and a quick intervention has a positive impact on the survival of the patients with vital emergency or traumatic conditions.
