Emergency department utilisation and treatment for trauma-related presentations of adolescents aged 16-18: a retrospective cross-sectional study.

BACKGROUND: A recent study conducted at our tertiary hospital emergency department (ED) reviewed ED consultations and found that adolescents aged 16-18 years present significantly more often for trauma and psychiatric problems than adults over 18 years. Accidental injuries are one of the greatest health risks for children and adolescents. In view of the increased vulnerability of the adolescent population, this study aimed to further analyse trauma-related presentations in adolescents. METHODS: We conducted a single-centre, retrospective, cross-sectional study of all adolescent trauma patients aged 16 to 18 years presenting to the adult ED at the University Hospital (Inselspital) in Bern, Switzerland, from January 2013 to July 2017. We analysed presentation data as well as inpatient treatment and cost-related data. Data of female and male patients were compared by univariable analysis. A comparison group was formed consisting of 200 randomly chosen patients aged 19-25 years old with the same presentation characteristics. Predictive factors for surgical treatment were obtained by multivariable analysis. RESULTS: The study population included a total of 1,626 adolescent patients aged 16-18 years. The predominant causes for ED presentation were consistent within case and comparison groups for sex and age and were sports accidents, falls and violence. Male patients were more likely to need surgical treatment (OR 1.8 [95% CI: 1.2-2.5], p = 0.001) and consequently inpatient treatment (OR 1.5 [95% CI: 1.1-2.1], p = 0.01), associated with higher costs (median 792 Swiss francs [IQR: 491-1,598]). Other independent risk factors for surgical treatment were violence-related visits (OR 2.1 [95% CI: 1.3-3.5, p = 0.004]) and trauma to the upper extremities (OR 2.02 [95% CI: 1.5-2.8], p < 0.001). Night shift (OR 0.56 [95% CI: 0.37-0.86], 0.008) and walk-in consultations (OR 0.3 [95% CI: 0.2; 0.4, < 0.001] were preventive factors for surgical treatment. CONCLUSIONS: Male adolescents account for the majority of emergency visits and appear to be at higher risk for accidents as well as for surgical treatment and/or inpatient admission due to sports accidents or injuries from violence. We suggest that further preventive measures and recommendations should be implemented and that these should focus on sport activities and injuries from violence.

Who Let the Dogs Out? Unmasking the Neglected: A Semi-Systematic Review on the Enduring Impact of Toxocariasis, a Prevalent Zoonotic Infection.

Toxocariasis remains an important neglected parasitic infection representing one of the most common zoonotic infections caused by the parasite Toxocara canis or, less frequently, by Toxocara cati. The epidemiology of the disease is complex due to its transmission route by accidental ingestion of embryonated Toxocara eggs or larvae from tissues from domestic or wild paratenic hosts. Even though the World Health Organization and Centers for Disease Control classified toxocariasis amongst the top six parasitic infections of priority to public health, global epidemiological data regarding the relationship between seropositivity and toxocariasis is limited. Although the vast majority of the infected individuals remain asymptomatic or experience a mild disease, the infection is associated with important health and socioeconomic consequences, particularly in underprivileged, tropical, and subtropical areas. Toxocariasis is a disease with multiple clinical presentations, which are classified into five distinct forms: the classical visceral larva migrans, ocular toxocariasis, common toxocariasis, covert toxocariasis, and cerebral toxocariasis or neurotoxocariasis. Anthelmintic agents, for example, albendazole or mebendazole, are the recommended treatment, whereas a combination with topical or systemic corticosteroids for specific forms is suggested. Prevention strategies include educational programs, behavioral and hygienic changes, enhancement of the role of veterinarians, and anthelmintic regimens to control active infections.

Imaging of alert patients after non-self-inflicted strangulation: MRI is superior to CT.

OBJECTIVE: To assess the accuracy of CT and MRI reports of alert patients presenting after non-self-inflicted strangulation (NSIS) and evaluate the appropriateness of these imaging modalities in NSIS. MATERIAL AND METHODS: The study was a retrospective analysis of patient characteristics and strangulation details, with a comparison of original radiology reports (ORR) to expert read-outs (EXR) of CT and MRI studies of all NSIS cases seen from 2008 to 2020 at a single centre. RESULTS: The study included 116 patients (71% women, p < .001, χ2), with an average age of 33.8 years, mostly presenting after manual strangulation (97%). Most had experienced intimate partner violence (74% of women, p < .001, χ2) or assault by unknown offender (88% of men, p < 0.002 χ2). Overall, 132 imaging studies (67 CT, 51% and 65 MRI, 49%) were reviewed. Potentially dangerous injuries were present in 7%, minor injuries in 22%, and no injuries in 71% of patients. Sensitivity and specificity of ORR were 78% and 97% for MRI and 30% and 98% for CT. Discrepancies between ORR and EXR occurred in 18% of all patients, or 62% of injured patients, with a substantial number of unreported injuries on CT. CONCLUSIONS: The results indicate that MRI is more appropriate than CT for alert patients presenting after non-self-inflicted strangulation and underline the need for radiologists with specialist knowledge to report these cases in order to add value to both patient care and potential future medico-legal investigations. CLINICAL RELEVANCE STATEMENT: MRI should be preferred over CT for the investigation of strangulation related injuries in alert patients because MRI has a higher accuracy than CT and does not expose this usually young patient population to ionizing radiation. KEY POINTS: • Patients presenting after strangulation are often young women with a history of intimate partner violence while men typically present after assault by an unknown offender. • Expert read-outs of CT and MRI revealed potentially dangerous injuries in one of 14 patients. • MRI has a significantly higher sensitivity than CT and appears to be more appropriate for the diagnostic workup of alert patients after strangulation.

Sex differences in sledging injuries: a retrospective 10-season study from a Swiss level 1 trauma centre.

Objectives: Sledging is a popular and traditional winter sport in Switzerland. This study examines injury patterns of patients who presented to a tertiary trauma centre in Switzerland following sledging trauma, focusing on sex differences. Methods: Retrospective single-centre study over 10 winters (2012-2022), including all patients experiencing sledging-related trauma. Injury history was collected and analysed from the patient data and demographic information. The Abbreviated Injury Scale and the Injury Severity Score (ISS) were used to classify injury types and severity. Results: 193 patients were identified with sledging injuries. The median age was 46 (IQR 28-65), and 56% were female. The most frequent mechanism of injury was a fall (70%), followed by collision (27%) and other fall on slopes (6%). Lower extremities (36%), trunk (20%) and head/neck (15%) were the most frequently injured body areas. Fourteen per cent of patients were admitted with head injuries, whereas females were significantly more likely to present with head injuries than males (p=0.047). Males were significantly more often admitted with fractures to the upper extremities than females (p=0.049). The median ISS was 4 (IQR 1-5), without significant differences between males and females (p=0.290). The hospital admission rate was 28.5% for sledging-related injuries. The median length of stay for patients admitted to the hospital was 5 (IQR 4-8) days. The total cost for all patients was CHF1 292 501, with a median of CHF1009 per patient (IQR CHF458-CHF5923). Conclusion: Sledging injuries are common and may result in serious injuries. The lower extremities, trunk and head/neck are frequently injured and could be specifically protected with safety devices. Multiple injuries were statistically more frequent in women compared with men. Males were significantly more often admitted with fractures to the upper extremities, and females were more likely to sustain head injuries. The findings can help to develop data-driven measures to prevent sledging accidents in Switzerland.

Presentation and treatment of animal and human bite injuries at a Swiss tertiary emergency department: a cross-sectional study.

BACKGROUND: Animal and human bite injuries are a relevant health problem worldwide. With the increasing number of pets, bite injuries are becoming more frequent. Previous studies on animal and human bite injuries in Switzerland were completed several years ago. The aim of the present study was to provide a detailed overview of patients with bite injuries admitted to a tertiary emergency department in Switzerland in terms of demographics, injury patterns and treatment strategies. METHODS: A 9-year cross-sectional analysis of patients presenting to the emergency department of Bern University Hospital in the period January 2013 to December 2021 following an animal or human bite injury. RESULTS: A total of 829 patients with bite injuries were identified, including 70 for postexposure prophylaxis only. Their median age was 39 (IQR 27-54) years and 53.6% were female. Most patients were bitten by a dog (44.3%), followed by cats (31.5%) and humans (15.2%). Most bite injuries were mild (80.2%); severe injuries were mainly found in dog bites (28.3%). Most patients were treated within six hours after human (80.9%) or dog (61.6%) bites; after cat bites, patients often presented with a delay (74.5%) and signs of infection (73.6%). Human bite wounds were superficial in the majority of cases (95.7%), rarely showed signs of infection (5.2%) at the time of presentation and hospitalisation was never required. CONCLUSIONS: Our study provides a detailed overview of patients admitted to an emergency department of a tertiary Swiss University Hospital after an animal or human bite. In summary, bite injuries are common among patients who present to the emergency department. Therefore, primary and emergency care clinicians should be familiar with these injuries and their treatment strategies. The high risk of infection, particularly in cat bites, may warrant surgical debridement in the initial treatment of these patients. Prophylactic antibiotic therapy and close follow-up examinations are recommended in most cases.

Use of epinephrine in anaphylaxis: a retrospective cohort study at a Swiss university emergency department.

AIMS OF THE STUDY: Anaphylaxis is a medical emergency and requires prompt treatment to prevent life-threatening conditions. Epinephrine, considered as the first-line drug, is often not administered. We aimed first to analyse the use of epinephrine in patients with anaphylaxis in the emergency department of a university hospital and secondly to identify factors that influence the use of epinephrine. METHODS: We performed a retrospective analysis of all patients admitted with moderate or severe anaphylaxis to the emergency department between 1 January 2013 and 31 December 2018. Patient characteristics and treatment information were extracted from the electronic medical database of the emergency department. RESULTS: A total of 531 (0.2%) patients with moderate or severe anaphylaxis out of 260,485 patients admitted to the emergency department were included. Epinephrine was administered in 252 patients (47.3%). In a multivariate logistic regression, cardiovascular (Odds Ratio [OR] = 2.94, CI 1.96-4.46, p <0.001) and respiratory symptoms (OR = 3.14, CI 1.95-5.14, p<0.001) were associated with increased likelihood of epinephrine administration, in contrast to integumentary symptoms (OR = 0.98, CI 0.54-1.81, p = 0.961) and gastrointestinal symptoms (OR = 0.62, CI 0.39-1.00, p = 0.053). CONCLUSIONS: Less than half of the patients with moderate and severe anaphylaxis received epinephrine according to guidelines. In particular, gastrointestinal symptoms seem to be misrecognised as serious symptoms of anaphylaxis. Training of the emergency medical services and emergency department medical staff and further awareness are crucial to increase the administration rate of epinephrine in anaphylaxis.

Trauma Characteristics Associated with E-Scooter Accidents in Switzerland-A Case Series Study.

E-scooters have gained popularity worldwide in the last few years. Due to the increase in users, more accidents related to e-scooters can be observed. The present study aimed to analyse epidemiological data, characteristics, and severity of injuries in patients admitted to a Level I trauma centre in Switzerland (Inselspital Bern, University Hospital Bern) after accidents associated with e-scooters. This retrospective case series evaluated 23 patients who presented to the University Hospital of Bern between 1 of May 2019 and 31 of October 2021 after an e-scooter accident. Data were collected on patient demographics, time and cause of the accident, speed, alcohol consumption, helmet use, type and localisation of injury, number of injuries per patient, and outcome. Men were most frequently affected (61.9%). The mean age was 35.8 (STD 14.8) years. Slightly more than half (52.2%) of all accidents were self-inflicted. Most accidents were reported during the night (7 p.m. to 7 a.m., 60.9%) and in summer (43.5%). Alcohol consumption was reported in 43.5% of cases, with a mean blood alcohol level of 1.4 g/l. Most injuries were observed in the face (25.3%) and head/neck area (20.25%). Skin abrasions (56.5%) and traumatic brain injury (43.5%) were the most common types of traumata in terms of total number of patients. Only in one case it was reported that a protective helmet had been worn. Five patients required hospitalisation and four patients underwent surgery. Three patients underwent emergency orthopaedic surgery, and one patient underwent emergency neurosurgery. E-scooter accidents result in a significant number of facial and head/neck injuries. E-scooter riders would potentially benefit from a helmet to protect them in the event of an accident. Additionally, the results of this study indicate that a significant number of e-scooter accidents in Switzerland occurred under the influence of alcohol. Prevention campaigns to raise awareness of the risks of driving e-scooters under the influence of alcohol could help prevent future accidents.

Injury patterns of non-fatal accidents related to ice hockey, an analysis of 7 years of admission to a Level-1 Emergency Centre in Switzerland.

OBJECTIVE: This study was carried out to identify the frequency and types of injuries in adult ice hockey, in order to better understand injury patterns and identify potential areas for injury prevention. METHODS: We conducted a retrospective database review of acute injuries reported in ice hockey in patients presenting to a Level-1 adult Emergency Centre in Switzerland. Patients between January 1, 2013 and December 31, 2019 and over 16 years of age were identified in our computerised patient database. Each consultation was reviewed to derive information on demographics, playing level and the features of the injury, including location, type, mechanism and consequences. Different age groups were compared, as were amateur and professional players. A statistical analysis was performed. RESULTS: A total of 230 patients were identified. The most common diagnoses were fracture (28.3%), contusion/abrasion (23.9%), laceration (12.6%) and concussion (10.4%). The most commonly affected body parts were the face (31.3%), the shoulder/clavicle (13.0%) and the head (12.2%). Most lesions were caused by player-player contact (37.4%), contact with the puck (24.3%) and falls (10.9%). In comparison to the younger cohorts, patients >36 years of age more frequently suffered injuries caused by falls, (p < 0.001) and were less frequently injured by player-player contact (p = 0.01813). In amateur players, significantly more injuries were caused by stick contact (OR 0, 95% CI (0.00-0.83), p = 0.02) and surgery was more rarely performed (OR 2.35, 95% CI 0.98-5.46, p = 0.04). CONCLUSIONS: Injuries continue to play a major role in ice hockey, especially in the face and due to player-player contact. Future investigations should focus on player-player contact and possible effective preventive measures. Players must be encouraged to employ face protection and to wear a mouth guard at all times.

Characteristics of emergency department presentations following ingestion of Taxus baccata (yew).

OBJECTIVE: Presentations of Taxus baccata (yew) poisoning can range between asymptomatic cases and life-threatening cardiotoxicity - depending on the amount ingested. This study aimed to describe emergency department (ED) presentations after yew exposure, and covers their clinical presentation, diagnostic and specific treatment, to contribute to optimising intreatment and prophylaxis. METHODS: Retrospective observational study of cases (≥ 16 years of age) presenting at the ED of the University Hospital of Bern, Switzerland, from 1 May 2012 to 31 May 2020 following reported yew exposure. Cases were retrieved from the electronic patient database using full-text terms. RESULTS: During the study period, 55 presentations (11 patients) of the 350,381 ED attendances were included. All patients were female and the median age on first presentation was 22 years (range 16-48). All 10 patients with intentional intake had previous diagnoses of psychiatric disorders. Commonly reported symptoms on presentation were gastrointestinal disturbances (31 presentations, 56%), neurological (six presentations, 11%) and subjective cardiovascular symptoms (five presentations, 9%). The most frequent clinical findings on presentation were tachycardia (15 presentations, 27%) and hypotension (11 presentations, 20%). In 52 presentations (95%), gastroscopic extraction of the leaves was performed, activated charcoal was administered in 25 cases (45%), and there were no fatalities. In the majority of the cases (40, 73%), the patient was admitted to psychiatric care and in 10 (18%) the patient was discharged home. CONCLUSION: ED presentations after yew exposure appear to be rare, but potentially life-threatening and commonly observed in this study in young female patients with underlying psychiatric diseases. In this case series, gastroscopic extraction and activated charcoal application were commonly performed and there were no fatalities.

[Dooring Bicycle Accidents with Severe Injury Patterns: 10-Year Study of a Level 1 Trauma Center]. / Dooring-Fahrradunfälle mit schweren Verletzungsmustern: 10-Jahres-Studie eines Level-1-Traumazentrums.

Dooring Bicycle Accidents with Severe Injury Patterns: 10-Year Study of a Level 1 Trauma Center Abstract. Studies in Switzerland, Germany and Austria have shown that, contrary to popular belief, dooring accidents are among the most common bicycle accidents. The resulting injuries are often serious and often lead to hospital admission. All dooring accidents of the Inselspital Emergency Department in Bern between 2012 and 2021 were identified and evaluated retrospectively. The data were generated from the database of the management system (Ecare) of the University Hospital Bern by means of a search query with the German keywords: "Autotüre", "Autotuere", "Dooring" and were anonymised. Most patients were female and on average 34 years old; most injuries occurred to the head and the extremities. Treatment was mostly done on an outpatient basis. The ISS (Injury Severity Score) was an average of 3.5. One of the patients needed emergency surgery. This is the first Swiss study to systematically record and evaluate dooring accidents. Since cycling is a trend, especially in urban areas, and consequently the number of cyclists is constantly increasing, it can be assumed that the number of dooring injuries will also increase and corresponding prevention measures will have to be taken. The current COVID-19 pandemic tends to aggravate the problem, as in the context of infection control the number of cyclists and, consequently, accidents is increasing, especially in urban areas, in the context of infection control. This said, it is crucial to gain more information about the time slots of the accidents and the casualties through appropriate studies in order to take adequate preventive and protective measures.

Presentations to the Emergency Department for Problems Related to Mental Health: Sex Differences in Adolescents.

BACKGROUND: Adolescents aged sixteen to eighteen years are mostly treated in adult emergency departments. In a study at our tertiary adult emergency department (ED) at the University Hospital in Bern (Inselspital), Switzerland, we found that adolescents significantly more often present with psychiatric problems than adults. The study at hand aimed to characterise those adolescents presenting to the ED triaged with a chief complaint regarding mental health. Furthermore, the goal was to assess sex differences in terms of diagnosis, suicidal ideation, substance use, as well as social impact. METHODS: We conducted a single-centre, retrospective review of presentations to our adult ED related to the mental health of adolescents aged 16 to 18 years, covering the period from January 2013 to July 2017. Anonymised data were extracted from medical reports referring to the ED visits that were triaged as mental-health-related, and we assessed these for diagnosis, acute and previous suicidal ideation, history of self-harm, external aggression, substance use and social problems. We focused on patient characterisation and defining sex differences. RESULTS: Data were analysed for a total of 612 consultations by adolescents who presented to our ED with problems related to mental health. Women accounted for 61.1% of cases. The most frequent diagnoses were reactions to severe stress and adjustment disorders (19.1%), followed by alcohol use disorders (17.6%), intentional self-harm (17.3%), and affective disorders (13.7%). Males had lower odds for intentional self-harm (OR 0.10, 95% 0.05-0.21, p < 0.001) as well as disorders of personality and behaviour (OR 0.09, 95% 0.21-0.37, p < 0.001), whereas they had higher odds of being admitted due to use of alcohol (OR 2.51, 95% 1.65-3.83, p < 0.001). Of all cases, 31.7% reported acute suicidal ideation, with a significantly lower odds ratio in males (OR 0.58, 95% 0.41-0.84, p = 0.004). The most common source for referral to the ED was family members (25.2%). Males had twice the odds of reporting alcohol consumption as well as use of cannabis (in both cases p < 0.001). In 27.9% of all cases, familial problems were reported, with males having significantly lower odds of being exposed to these (OR 0.64, 95% 0.44-0.94, p = 0.021), whereas they had higher odds of reporting educational problems (OR 1.68, 95% 1.04-2.72, p = 0.035). CONCLUSIONS: Adolescents aged sixteen to eighteen years presenting to the ED with problems related to mental health are an important subgroup of ED presentations and should be thoroughly assessed for suicidal ideation, substance use, as well as familial and educational problems. Assessment and establishment of post-ED care are of particular importance in this vulnerable patient group.

Work-Related Injuries among Insured Construction Workers Presenting to a Swiss Adult Emergency Department: A Retrospective Study (2016-2020).

Occupational injuries are one of the main causes of Emergency Department visits and represent a substantial source of disability or even death. However, the published studies and reports on construction-occupational accidents in Switzerland are limited. We aimed to investigate the epidemiology of fatal and non-fatal injuries among construction workers older than 16 years of age over a 5-year period. Data were gathered from the emergency department (ED) of Bern University Hospital. A retrospective design was chosen to allow analysis of changes in construction accidents between 2016-2020. A total of 397 patients were enrolled. Compared to studies in other countries, we also showed that the upper extremity and falling from height is the most common injured body part and mechanism of injury. Furthermore, we were able to show that the most common age group representing was 26-35 years and the second common body part injured was the head, which is a difference from studies in other countries. Wound lacerations were the most common type of injury, followed by joint distortions. By stratifying according to the season, occupational injuries among construction workers were found to be significant higher during summer and autumn. As work-related injuries among construction workers are becoming more common, prevention strategies and safety instructions must be optimized.

Health Status of Afghan Refugees in Europe: Policy and Practice Implications for an Optimised Healthcare.

Four decades of civil war, violence, and destabilisation have forced millions of Afghans to flee their homes and to move to other countries worldwide. This increasing phenomenon may challenge physicians unfamiliar with the health status of this population, which may be markedly different from that of the host country. Moreover, several factors during their migration, such as transport in closed containers, accidental injuries, malnutrition, and accommodation in detention centres and refugee camps have a major influence on the health of refugees. By taking into account the variety of the specific diseases among migrant groups, the diversity of the origins of refugees and asylum seekers, and the increasing numbers of Afghan refugees, in this review we focus on the population of Afghans and describe their health status with the aim of optimising our medical approach and management. Our literature review shows that the most prevalent reported infections are tuberculosis and other respiratory tract infections and parasitic diseases, for example leishmaniasis, malaria, and intestinal parasitic infections. Anaemia, hyperlipidaemia, arterial hypertension, diabetes, smoking, overweight, malnutrition, low socioeconomic status, and poor access to healthcare facilities are additional risk factors for non-communicable diseases among Afghan refugees. With regards mental health issues, depression and post-traumatic stress disorder (PTSD) are the most common diagnoses and culture shock and the feeling of being uprooted modulate their persistence. Further research is needed in order to provide us with extensive, high-quality data about the health status of Afghan refugees. The main objective of this review is to identify protective factors which could ensure key health concepts and good clinical practice.

Cattle-related trauma: a 10-year retrospective cohort study of patients admitted to a single tertiary trauma centre in Switzerland.

AIMS OF THE STUDY: Switzerland is traditionally an agricultural country with more than 50,000 farms and 1.5 million registered cows. However, contemporary literature on cattle-related trauma in Switzerland remain limited. The purpose of this study was to examine injury patterns and outcomes of patients who presented to a tertiary trauma centre in Switzerland following cattle-related trauma. METHODS: Retrospective single-centre study over a 10-year period (2012-2021) including all patients experiencing cattle-related trauma. From retrieved charts demographics, injury data, and outcomes were collected and subsequently analysed. RESULTS: A total of 94 patients with cattle-related injuries were identified. The median age was 52 years (interquartile range [IQR] 37-63) and 75% were male. Cattle-related injuries were most frequent among farmers (73%) and were most often caused by cows (86%), followed by bulls (10%). Blunt trauma (89%) was the leading mechanism of injury including headbutt (36%), kick (35%), physical contact (20%) and trampling injury (12%). Penetrating injury occurred in 11%, all caused by headbutt. Contusions (82%) and lacerations (45%) were the leading injuries, followed by face fractures (28%), closed head trauma (19%) and chest injuries (17%). Overall, 10% of all patients had a head abbreviated injury scale (AIS) score of ≥3 and 8% had a chest AIS of ≥3. The hospital admission rate was 49% for cow-related injury vs 90% for bull-related injuries, p = 0.023. Overall, in-hospital mortality was 3% and the median length of stay was 4.5 days (IQR 3-8) among patients admitted to the hospital. CONCLUSIONS: Cattle-related injuries in Switzerland mainly affect farmers and are associated with considerable morbidity, especially when caused by bulls. Facial fractures, head injuries and chest injuries are common, and the latter two in particular can be severe. The results of the present study can be used for the implementation of data-driven prevention measures for the safe handling of cattle in Switzerland.

Injuries in outdoor climbing: a retrospective single-centre cohort study at a level 1 emergency department in Switzerland.

Objectives: Outdoor rock climbing has become popular in recent years. However, few data have been published on climbing accidents in Switzerland, even though the Swiss Alps are a major climbing resort.To analyse data on accidents related to outdoor climbing treated in the Emergency Department (ED) of University Hospital Bern, Switzerland. Methods: A retrospective database search for accidents related to outdoor climbing was conducted in the clinical reporting system E.care of the ED of University Hospital Bern for the period April 2012-December 2018. Results: 78 patients were treated after an accident related to outdoor climbing, which accounted for 1 per 3571 (0.028%) of all ED visits during this period. Mean age was 35.8±10.4 years. 76% of patients were male. Falls were the most common mechanism of injury (64%), followed by rock or ice falling on the climber (21%). Injuries affected multiple body regions (38%) or only the lower limbs (22%). Most injuries were fractures (68%). Mean ISS was 7.5 (1-38), and grade 3 UIAA MedCom injuries were most common (45%). 11 cases of polytrauma occurred and one fatality. 44 patients needed inpatient admission. Mean duration of inpatient stay was 7 days. Mean costs per patient were 12 283 CHF. Conclusions: Accidents related to outdoor climbing accounted for a small number of patients seen in the University ED Bern. Further research should be on a nationwide basis, with collection of specific climbing data like use of a helmet and experience of climbing to inform injury prevention strategies. This should shed further light on this topic, as would a prospective study using the International Alpine Trauma Register.

Trampolining Accidents in an Adult Emergency Department: Analysis of Trampolining Evolution Regarding Severity and Occurrence of Injuries.

PURPOSE: Only a few studies have been conducted on trampoline-associated injuries in adults, especially in Switzerland. The aim of the present study was to describe the characteristics of trampoline-related injuries in patients older than 16 years of age and track their development over time by comparing two different time periods. METHODS AND MATERIALS: Data were gathered from the emergency department (ED) of Bern University Hospital. A retrospective design was chosen to allow analysis of changes in trampolining accidents between 2003-2020. RESULTS: A total of 144 patients were enrolled. The number of ED presentations due to trampoline-related injury rose significantly over time. The most common injuries were sprains to the extremities (age group 31-62: 58.4% and age group 16-30: 50.8%), followed by fractures (age group 31-62: 33.3% and age group 16-30: 32.5%). Lower extremities appeared to be the most frequently injured body region (age group 31-62: 20.8% and age group 16-30: 10.0%), although the differences were not statistically significant, p = 0.363. BMI was significantly higher for older than for younger patients (p = 0.004). CONCLUSION: Over the last two decades, trampoline-related injuries have become more common in patients older than 16 years of age. These are most common in the lower extremities. While most of the patients in the present study only suffered minor injuries, the occasional severe injury might result in long-term disability. As trampoline-related injuries in adults are becoming more common, prevention strategies in public education and safety instructions must be optimised.

Presentations with reported methamphetamine use to an urban emergency department in Switzerland.

AIMS OF THE STUDY: The stimulant methamphetamine (e.g., "crystal meth") is a commonly abused drug in many parts of the world and can cause significant health problems. The present study aims to describe presentations with reported methamphetamine use at an urban emergency department (ED) in Switzerland, to investigate prevalence, patterns and susceptible groups. METHODS: Retrospective study at the ED of the University Hospital of Bern, Switzerland. Cases from June 2012 to July 2019 were retrieved from the electronic patient database using full-text terms and were categorised into three groups based on patient history: "acute", if patients presented within 72 hours of last reported use, "chronic" in cases of regular use but not within the previous 72 hours, and "past" in cases of discontinued consumption. Cases with a positive methamphetamine urine drug screening test with no further information available were described separately. RESULTS: During the study period, 40 cases were categorised as "acute". Among those, the mean age was 29.5 years (standard deviation [SD] 8.7), 75% (n = 30) were male, and agitation (n = 11, 28%), hypertension (n = 11, 28%), tachycardia (n = 11, 28%), sleep disturbances (n = 10, 25%) and aggression (n = 8, 20%) were the most common symptoms. Most patients (n = 22, 55%) were medically discharged, but 35% (n = 14) were admitted to a psychiatric clinic. Most (n = 33, 82.5%) were polydrug users, with alcohol, cocaine and cannabis being the most frequent co-used substances. The "chronic" group included 37 cases. Those patients were mostly male (n = 26, 70%), with a mean age of 31 years (SD 11.0), and 46% (n = 17) presented because of psychiatric symptoms, such as psychosis, depression or aggression. Of the 45 cases in the "past" group (mean age of 30 years, SD 8.6), 69% (n = 31) were male, and 49% (n = 22) and 24% (n = 11), respectively, had medical and psychiatric symptoms as the reason for admission. Of 61 cases with a positive urine drug screening test as the sole indicator of methamphetamine use, 19 patients reported MDMA use (cross-reactivity with methamphetamine in the urine immunoassay used). In the 42 remaining cases, it was unclear if the positive result was due to unreported methamphetamine use or cross-reactivity. CONCLUSIONS: Most patients with reported methamphetamine use were young and male, with signs of sympathomimetic arousal and/or psychiatric symptoms. Although ED visits with reports of methamphetamine use appear to be uncommon, consumption-related health problems can require significant pre- and in-hospital resources.

Lessons Learned - Observational Study After One Year of 'Domestic Violence Consultation' at the University Emergency Department Bern Abstract. The number of violent crimes in domestic violence has been steadily increasing in Switzerland since 2011. In November 2018, the University Emergency Department Bern established standardized care for victims of domestic violence with an integrated follow-up. In this retrospective study, the results one year after the establishment of the special consultation hour as well as the challenges are presented. Of the 53 individuals primarily treated at the emergency department for domestic violence, 69.8 % (n = 37) were offered a follow-up appointment. Specific subgroups were less likely to be offered follow-up appointments. It became apparent that despite instructions for action and training, not all affected groups were perceived in the same way.

Clinical Presentations of Adolescents Aged 16-18 Years in the Adult Emergency Department.

BACKGROUND: In many large hospitals in Switzerland, adolescents 16 years and older are treated in adult emergency departments (ED). There have been few publications about this specific patient population, especially in Switzerland. This study aims to provide an overview of emergency presentations of adolescents between 16-18 years of age when compared to adults and focuses on their principle complaints. METHODS: We conducted a single-centre, retrospective, cross-sectional study of all patients aged 16 years and older presenting to the adult ED at the University Hospital (Inselspital) in Bern, Switzerland, from 2013 to 2017. This analysis gives an overview of emergency presentations of adolescents between 16-18 years of age in this time period and compares their consultation characteristics to those of adult patients. RESULTS: Data of a total of 203,817 patients who presented to our adult ED between 2013 and 2017 were analysed. Adolescents account for 2.5% of all emergency presentations. The number of ED presentations in the reviewed time period rose for adults (+2368, 95% CI: 1695, 3041, p = 0.002 consultations more per year; +25% comparing 2013 with 2017), while adolescent presentations did not significantly increase (p = 0.420). In comparison to adult patients, adolescents presented significantly more often during the night (39.1% vs. 31.5%, p < 0.001), as walk-ins (54.2% vs. 44.9%, p < 0.001), or with less highly acute complaints at triage (21% vs. 31%, p < 0.001). They were more likely to be discharged (70.8% vs. 52.2%, p < 0.001). We found a significant association between the two age groups and principle complaints. In comparison to adults, trauma and psychiatric problems were significantly more common among adolescents. CONCLUSIONS: Our data showed that complaints in adolescent patients under 18 years of age significantly differ from those in older patients. The artificial age cut-off therefore puts this vulnerable population at risk of receiving inadequate diagnostic testing and treatment adapted only for adults. Additional studies are needed on the reasons adolescents and young adults seek ED care, as this could lead to improvements in the care processes for this vulnerable population.

Floorball Injuries Presenting to a Swiss Adult Emergency Department: A Retrospective Study (2013-2019).

BACKGROUND: The popularity of floorball has surged throughout Switzerland in the last 20 years. However, epidemiological studies are still scarce. OBJECTIVE: To collect information on floorball-related injuries, their severity and approximate cost in adults who presented to our emergency department from 2013-2019. Moreover, to use this information to suggest possible strategies to prevent injuries. MATERIALS AND METHODS: The study population includes all patients who suffered injuries related to floorball and were then seen at the University Hospital in Bern during a 7-year period. Bern University Hospital, Switzerland, has a comprehensive management system (Ecare) that was used to generate the data for this study. The data were then used to create an injury profile of all cases presented during the said period. RESULTS: A total of 263 injures were recorded from 2013 to 2019. The most common locations for injuries were to the eyes (43.73%), followed by the lower extremities (25.48%). The mean cost per case was CHF 1191.43. However, the vast majority of admissions could be sent home (93.16%) and did not cost more than 500 CHF/case (57.41%). Of the 22 cases that cost more than CHF 2000, 10 were located around the torso and 6 affected one or both eyes. Significant differences were observed between the age groups and treatment area (p =0.008), costs (p =0.008), route of discharge (p =0.023) and type of trauma (p =0.020). CONCLUSION: Although floorball is still a relatively minor sport, its impact on sport-related injuries must not be underestimated. Injuries to the eyes are particularly common. In our opinion, our findings provide strong evidence that all floorball players (not only children and adolescents) should wear protective eyewear. We conclude that the Swiss Floorball Association (Swiss Unihockey) should mandate the use of protective eyewear.
