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.

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 between female and male patients were compared with 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 operative treatment were obtained by multivariable analysis. Results The study population included a total of 1,626 adolescent patients aged 16–18 years. The predominant cause for ED presentation (consistent within case and comparison groups for sex and age) 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 Swissfrancs [IQR: 491-1,598]). Other independent risk factors for operative treatment were violence-related visits (OR 2.1 [95% CI: 1.3–3.5, p = 0.004]) and upper extremity trauma (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 operative treatment. Conclusions Male adolescents account for the majority of emergency visits and appear to be at higher risk for accidents as well as surgical treatment and/or inpatient admission due to sports accidents or injuries obtained through violence. We suggest the implementation of further preventive measures and recommendations with a focus on sport activities and violence related injuries.
