Background: To investigate the management of children and adolescents with isolated and combined chest trauma in pediatric (PD) and non-pediatric departments (non-PD). Methods: Anonymized claims data were provided by two large German statutory health insurance funds, covering 6.3 million clients over a 10-year period (2010–2019). Data were extracted for patients who had an inpatient ICD diagnosis of section S20–S29 (injuries to the thorax) and were ≤18 years of age. Demographic and clinical data were analyzed. Results: A total of 4064 children and adolescents with chest trauma were included (mean age 12.0 ± 5.0 years; 55% male). In 1928 cases (47.4%), treatment was provided at PD. Patients admitted to PD underwent CT imaging less frequently (8.1%; non-PD: 23.1%; p < 0.0001). Children with a chest drain treated at university/maximum care hospitals (UM) showed more injuries involving multiple body regions compared with non-UM (25.8% vs. 4.5%; p = 0.0061) without a difference in the length of hospital stay. Conclusion: Children and adolescents with chest trauma are treated almost equally often in pediatric and adult departments. CT is significantly less frequently used in pediatric departments. Patients with a chest drain treated at a UM showed more concomitant injuries without a longer hospital stay. However, the clinical validity of this finding is questionable.

Background: Ovarian torsion (OT) is a rare but urgent surgical condition in children and adolescents. Evidence on how management differs between pediatric (PD) and non-pediatric (Non-PD) departments in Germany remains limited. Methods: We conducted a retrospective cohort study using anonymized claims data from two major German statutory health insurance funds (2010–2019), covering 6.3 million insured individuals (≈1 million children). Patients ≤18 years with an inpatient diagnosis of OT (ICD-10-GM N83.5) were analyzed with respect to demographics, department type (PD vs. Non-PD), hospital type (university/maximum care [UM] vs. non-university/maximum care [Non-UM]), surgical procedures, and outcomes. Results: A total of 293 patients (mean age 12.4 ± 4.5 years) were included; 71% were adolescents (12–18 years). Adolescents were predominantly treated in Non-PD (89%), whereas younger children were more often managed in PD (50%; p < 0.0001). Most cases were treated in Non-UM (82%). Laparoscopy was more commonly used in Non-PD departments (85%), while open surgery and oophorectomy occurred more frequently in PD and university hospitals (UM). Ovary-sparing procedures accounted for 77% of all cases, whereas 23% underwent oophorectomy. Mean hospital stay was longer in PD (6.7 ± 9.0 days) than in Non-PD (4.9 ± 2.2 days; p = 0.0167). Readmission rates were comparable across groups. Conclusions: Management of OT in Germany varies markedly by department and hospital type. PD and UM treat more younger patients but perform oophorectomy more frequently, whereas Non-PD and Non-UM favor laparoscopic, ovary-sparing strategies. These differences highlight the urgent need for standardized, evidence-based protocols prioritizing ovarian preservation and optimizing long-term outcomes in affected children and adolescents.
