Background Forced displacement related to persecution and violent conflict has reached a new peak in recent years. The primary aim of this study is to provide an initial overview of the acute and chronic health care problems of asylum seekers from the Middle East, with special emphasis on asylum seekers from Syria. Methods Our retrospective data analysis comprised adult patients presenting to our emergency department between 01.11.2011 and 30.06.2014 with the official resident status of an “asylum seeker” or “refugee” from the Middle East. Results In total, 880 patients were included in the study. Of these, 625 (71.0%) were male and 255 (29.0%) female. The median age was 34 (range 16–84). 222 (25.2%) of our patients were from Syria. The most common reason for presentation was surgical (381, 43.3%), followed by medical (321, 36.5%) and psychiatric (137, 15.6%). In patients with surgical presentations, trauma-related problems were most common (n = 196, 50.6%). Within the group of patients with medical presentation, acute infectious diseases were most common (n = 141, 43.9%), followed by neurological problems (n = 70, 21.8%) and gastrointestinal problems (n = 47, 14.6%). There were no differences between Syrian and non-Syrian refugees concerning surgical or medical admissions. The most common chronic disorder of unclear significance was chronic gastrointestinal problems (n = 132, 15%), followed by chronic musculoskeletal problems (n = 108, 12.3%) and chronic headaches (n = 78, 8.9%). Patients from Syria were significantly younger and more often suffered from a post-traumatic stress disorder than patients of other nationalities (p<0.0001, and p = 0.05, respectively). Conclusion Overall a remarkable number of our very young group of patients suffered from psychiatric disorders and unspecified somatic symptoms. Asylum seekers should be carefully evaluated when presenting to a medical facility and physicians should be aware of the high incidence of unspecified somatic symptoms in this patient population.In general, there is no major difference between asylum seekers from Syria when compared to other nationalities of asylum seekers from the Middle East.

BackgroundEmergency departments (EDs) are an essential component of any developed health care system. There is, however, no national description of EDs in Switzerland. Our objective was to establish the number and location of EDs, patient visits and flow, medical staff and organization, and capabilities in 2006, as a benchmark before emergency medicine became a subspecialty in Switzerland.MethodsIn 2007, we started to create an inventory of all hospital-based EDs with a preliminary list from the Swiss Society of Emergency and Rescue Medicine that was improved with input from ED physicians nationwide. EDs were eligible if they offered acute care 24 h per day, 7 days per week. Our goal was to have 2006 data from at least 80% of all EDs. The survey was initiated in 2007 and the 80% threshold reached in 2012.ResultsIn 2006, Switzerland had a total of 138 hospital-based EDs. The number of ED visits was 1.475 million visits or 20 visits per 100 inhabitants. The median number of visits was 8,806 per year; 25% of EDs admitted 5,000 patients or less, 31% 5,001-10,000 patients, 26% 10,001-20,000 patients, and 17% >20,000 patients per year. Crowding was reported by 84% of EDs with >20,000 visits/year. Residents with limited experience provided care for 77% of visits. Imaging was not immediately available for all patients: standard X-ray within 15 min (70%), non-contrast head CT scan within 15 min (38%), and focused sonography for trauma (70%); 67% of EDs had an intensive care unit within the hospital, and 87% had an operating room always available.ConclusionsSwiss EDs were significant providers of health care in 2006. Crowding, physicians with limited experience, and the heterogeneity of emergency care capabilities were likely threats to the ubiquitous and consistent delivery of quality emergency care, particularly for time-sensitive conditions. Our survey establishes a benchmark to better understand future improvements in Swiss emergency care.

BackgroundSedation is a procedure required for many interventions in the Emergency department (ED) such as reductions, surgical procedures or cardioversions. However, especially under emergency conditions with high risk patients and rapidly changing interdisciplinary and interprofessional teams, the procedure caries important risks. It is thus vital but difficult to implement a standard operating procedure for sedation procedures in any ED. Reports on both, implementation strategies as well as their success are currently lacking. This study describes the development, implementation and clinical evaluation of an interprofessional and interdisciplinary simulation-based sedation training concept.MethodsAll physicians and nurses with specialised training in emergency medicine at the Berne University Department of Emergency Medicine participated in a mandatory interdisciplinary and interprofessional simulation-based sedation training. The curriculum consisted of an individual self-learning module, an airway skill training course, three simulation-based team training cases, and a final practical learning course in the operating theatre. Before and after each training session, self-efficacy, awareness of emergency procedures, knowledge of sedation medication and crisis resource management were assessed with a questionnaire. Changes in these measures were compared via paired tests, separately for groups formed based on experience and profession. To assess the clinical effect of training, we collected patient and team satisfaction as well as duration and complications for all sedations in the ED within the year after implementation. We further compared time to beginning of procedure, time for duration of procedure and time until discharge after implementation with the one year period before the implementation. Cohen’s d was calculated as effect size for all statistically significant tests.ResultsFifty staff members (26 nurses and 24 physicians) participated in the training. In all subgroups, there is a significant increase in self-efficacy and knowledge with high effect size (dz = 1.8). The learning is independent of profession and experience level. In the clinical evaluation after implementation, we found no major complications among the sedations performed. Time to procedure significantly improved after the introduction of the training (d = 0.88).DiscussionLearning is independent of previous working experience and equally effective in raising the self-efficacy and knowledge in all professional groups. Clinical outcome evaluation confirms the concepts safety and feasibility.ConclusionAn interprofessional and interdisciplinary simulation-based sedation training is an efficient way to implement a conscious sedation concept in an ED.

BACKGROUND Mortality and morbidity are particularly high in the building industry. The annual rate of non-fatal occupational accidents in Switzerland is 1,133 per 100,000 inhabitants. METHODS Retrospective analysis of the electronic database of a university emergency centre. Between 2001 and 2011, 782 occupational accidents to construction workers were recorded and analysed using specific demographic and medical keywords. RESULTS Most patients were aged 30-39 (30.4%). 66.4% of the injured workers were foreigners. This is almost twice as high as the overall proportion of foreigners in Switzerland or in the Swiss labour market. 16% of the Swiss construction workers and 8% of the foreign construction workers suffered a severe injury with ISS >15. There was a trend for workers aged 60 and above to suffer an accident with a high ISS (p = 0.089). CONCLUSIONS As in other European countries, most patients were in their thirties. Older construction workers suffered fewer injuries, although these tended to be more severe. The injuries were evenly distributed through the working days of the week. A special effort should be made that current health and safety measures are understood and applied by foreign and older construction workers.

PRINCIPALS Accidents in agriculture are a problem of global importance. The hazards of working in agriculture are manifold (machines, animals, heights). We therefore assessed injury severity and mortality from accidents in farming. METHODS We retrospectively analysed all farming accidents treated over a 12-year period in the emergency department (ED) of our level I trauma centre. RESULTS Out of 815 patients 96.3% were male and 3.7% female (p <0.0001). A total of 70 patients (8.6%, 70/815) were severely injured. Patients with injuries to the chest were most likely to suffer from severe injuries (odds ratio [OR] 9.45, 95% confidence interval [CI] 5.59-16.00, p <0.0001), followed by patients with injuries to the abdomen (OR 7.06, 95% CI 3.22-15.43, p <0.0001) and patients with injuries to the head (OR 5.03, 95% CI 2.99-8.66, p <0.0001). Hospitalisation was associated with machine- and fall-related injuries (OR 22.39, 95% CI 1.95-4.14, p <0.0001 and OR 2.84 95% CI 1.68-3.41 p <0.001, respectively). Patients suffering from a fall and patients with severe injury were more likely to die than others (OR 3.32, 95% CI 1.07-10.29, p <0.037 and OR 9.17, 95% CI 6.20-13.56, p <0.0001, respectively). Fall height correlated positively with the injury severity score , hospitalisation and mortality (all p <0.0001). CONCLUSION Injuries in agriculture are accompanied by substantial morbidity and mortality, and range from minor injuries to severe multiple injuries. Additional prospective studies should be conducted on injury severity, long-term disability and mortality.

Background Extended focused assessment with sonography for trauma (eFAST) has been shown to have moderate sensitivity for detection of pneumothorax in trauma. Little is known about the location or size of missed pneumothoraces or clinical predictors of pneumothoraces in patients with false-negative eFAST. Methods This retrospective cross-sectional study includes all patients with multiple blunt trauma diagnosed with pneumothorax who underwent both eFAST and CT performed in the ED of a level 1 trauma centre in Switzerland between 1 June 2012 and 30 September 2014. Sensitivity of eFAST for pneumothorax was determined using CT as the gold standard. Demographic and clinical characteristics of those who had a pneumothorax detected by eFAST and those who did not were compared using the Mann-Whitney U or Pearson’s χ2 tests. Univariate binary logistic regression models were used to identify predictors for pneumothoraces in patients with negative eFAST examination. Results The study included 109 patients. Overall sensitivity for pneumothorax on eFAST was 0.59 and 0.81 for pneumothoraces requiring treatment. Compared with those detected by eFAST, missed pneumothoraces were less likely to be ventral (30 (47.6%) vs 4 (9.3%), p <0.001) and more likely to be apical and basal (7 (11.1%) vs 15 (34.9%), p=0.003; 11 (17.5%) vs 18 (41.9%), p=0.008, respectively). The missed pneumothoraces were smaller than the detected pneumothoraces (left side: 30.7±17.4 vs 12.1±13.9 mm; right side: 30.2±10.1 vs 6.9±10.2 mm, both p <0.001). No clinical variables were identified which predicted pneumothoraces in falsely negative eFAST. Among those pneumothoraces missed by eFAST, 30% required tube thoracostomy compared with 88.9% of those detected with eFAST. Conclusion In our study, pneumothoraces missed by eFAST were smaller and in atypical locations compared with those detected by eFAST and needed thoracic drainage less often.

BACKGROUND Burns in Switzerland are frequent and lead to high economic and social costs. However, little is known about the aetiology of burns suffered by patients seeking treatment in hospital emergency departments. This knowledge could be used to develop preventive measures. METHODS This retrospective analysis included all patients (≥16 years old) with acute thermal injuries of known cause admitted to the adult emergency department in Bern University Hospital (Switzerland, not a specialised burns unit) between 2000 and 2012. Clinical and sociodemographic data were extracted from medical records, i.e. the environment in which the burn occurred, as well as details of burn severity and aetiology. RESULTS Seven hundred and one (701) patients with a mean age of 35.0±14.5 years (56% men) were included in the analysis. The winter season and the days around Christmas, turn of the year and Swiss National Day were identified as times with high risk of burns. Household (45%) and workplace (31%) were the most common locations/settings in which the burns occurred. Approximately every second burn was caused by scald, every fourth by flame and every seventh by hot objects. The analysis identified cooking, tar and electricity in workplace accidents, barbecues and the use of gasoline as aetiological factors in burns in leisure time, together with water in domestic thermal injuries. Burns occurred predominantly on non-protected skin on the hand and arms. The most severe burns were seen in electrical and flame burns. Men suffered more severe burns than women in all settings except psychopathology. CONCLUSIONS The data suggest that the incidence and severity of burns in Switzerland could be reduced by preventive strategies and public campaigns, including education on fire protection systems, raising awareness about the times and locations where the risks of burns are greater, further improvement in workplace safety, particularly with cooking facilities and electrical equipment, and the development of innovative safety devices (i.e. machines, protective gloves). These findings have to be interpreted carefully, as this study includes only adult patients who presented in our ED and, in most cases, the burns covered less than 20% of the body surface.

As pointed out by Dr Buscher, only a very few patients in an emergency department are critically ill, and require a multidisciplinary team approach. Coordination of such a team requires specialists with the expertise to deal with impaired and rapidly changing vital functions. This is not about a specialty but about the right skills and understanding the acute care pathway. In most European countries, this function is fulfilled by anaesthesiologists/ intensivists (https://www.uems.eu/__data/assets/pdf_file/ 0007/19438/UEMS-2012.14-SECTIONS-AND-BOARDSChapter-6-Anaesthesiology.pdf, http://www.eba-uems. eu/resources/PDFS/Training/Anaesthesiology-TrainingRequirements-March-2013.pdf). Ideally, critical patients are identified in the prehospital period and then ‘railroaded’ into the appropriate care pathway. We agree with Dr Buscher that resuscitation of critically unwell patients needs to be done in close cooperation with intensive care experts, anaesthesiologists in most cases. As pointed out in our response to Hautz et al., we doubt whether emergency medicine as an independent specialty can support the required skills or the necessary pathway continuity.

Background This article addresses typical injury patterns related to the traditional Swiss folk wrestling, ‘Schwingen’. This is a fight between two competitors with its own rules, grips and throws. A variety of injuries have been occasionally reported. The aim of this study was to characterise all cases of Schwingen injuries treated in the University Hospital of Bern from January 2006 to July 2016. Methods To assess the frequency, type and outcome of Schwingen injuries, database search was performed of all inpatient and outpatient cases related to Schwingen that were admitted to Bern University Hospital from January 2006 to December 2016. Results A total of 32 such patients could be identified. Apart from a single woman, all patients were male. 31 of the 32 players were Swiss. One patient was admitted to the intermediate care unit, eight patients underwent surgery, two were hospitalised for further treatment and two were given a plaster. 17 other patients were given medications such as painkillers. One was dismissed without further treatment and another one left the hospital on his own. Typical injury patterns varied from simple lesions to distortions and fractures as well as head injuries and other neurological complications. Conclusion The majority of injuries caused by Schwingen are not life threatening. Nevertheless, there is always the potential of head injuries and neurological deficits. Apart from the economic loss due to treatment costs and sick leave, these injuries can be disabling for life. It should therefore be obligatory for all players to evaluate preventive measures.
