PurposeThe study investigates changes in the injury characteristics of hospitalised children in a paediatric trauma centre during the COVID-19 pandemic.MethodsData from injured children from the pre-pandemic year 2019 were compared to the pandemic year 2020 using Pearson's chi-squared test and the Mann-Whitney U test. The period of highly restrictive regulations (HRP) was evaluated separately. A comprehensive literature review with defined search terms resulted in a descriptive data synthesis.ResultsData from 865 patients indicated reductions in admissions of 5.6% and 54.4% during the HRP. In 2020, the hospitalisation time was longer (2.2 ± 2.7 days in 2019 vs. 2.4 ± 2.6 in 2020, p = 0.045); the proportions of wounds requiring surgical therapy (p = 0.008) and of observational treatments, primarily for mild brain injuries (p = 0.046), were higher; and conservative treatments, primarily for contusions, were lower (p = 0.005). There were no significant changes in age, location of lesions, or frequency of surgical therapy; nor were there differences in the HRP, except for fewer injuries in school and kindergarten (p < 0.001). The literature review summarises the main results of 79 studies.ConclusionLimited resources did not alter the indications for surgical therapy. Further studies should examine whether the more common injuries sustained at home were caused by excessive work/childcare demands on parents. Reduced inpatient conservative treatment implies that hospital resources possibly were overused previously. The literature offers answers to many detailed questions regarding childhood injuries during a pandemic and more efficient safe treatment.
