Paediatric traumatic brain injuries: A descriptive analysis of incidence, visits, cause, and admission rates in Iceland from 2010 to 2021

Abstract

Background

Traumatic brain injuries (TBI) are common in emergency departments (ED) and may cause long-term negative outcomes but knowledge on how the first assessment of children with TBI may predict outcomes is lacking. This study aimed to expand the knowledge by describing the incidence, visits, causes, and outcomes of TBI in children in Iceland.

Methods

A retrospective descriptive data analysis was conducted on electronic medical records of children aged 0–17 that visited Landspitali EDs due to a traumatic head injury in 2010–2021. Cases were based on registered ICD-10 diagnosis and data was collected on demographics, causes, triage, length of stay (LOS), admissions and mortality rates. Descriptive statistics were calculated, and associations of variables tested for significance.

Results

The study sample included 30,014 emergency visits. The majority involved boys (61.21 %) and children under 6 years old (57.99 %, M = 5.98 years). Girls had a significantly lower mean age (5.75 years vs 6.13 years, p < 0.001). The highest incidence was in one-year olds (729 per 100,000) and was on average 310 per 100,000 children of all ages. Total yearly visits decreased throughout the study period (M = 2,501). Emergency Severity Index (ESI) of 4 (50.77 %) was the most common, with 59.6 % of ESI = 1 cases admitted (p < 0.001). The average LOS was 2.2 h and 1.05 % were admitted. Falls (43.62 %) and soft tissue injuries (73.68 %) were the most common, with intracranial injuries (42.57 %) being the most common in ED observations and admissions. Throughout the study period, 30 (0.10 %) died, thereof three within a week post-injury. In total, 26.64 % of children had at least one revisit to the ED with a traumatic head injury.

Conclusions

Children commonly visit EDs due to TBI, mostly with mild injuries but one fourth revisited with a new head injury. There may be groups of children that require specialised follow-up care and assessment to detect and prevent further complications of TBI. Paediatric emergency nurses may be in a key position in identifying children in need of follow-up care. Further research is needed to enhance knowledge of outcomes of TBI in children and to reflect the important role of nurses in paediatric TBI care.
