Insights

Traumatic brain injury (TBI) hospitalizations in children decreased in 2020, with mild TBI cases showing the largest reduction. This suggests more mild TBI cases can be managed outpatient.

Area of Science:

  • Pediatric Emergency Medicine
  • Neurotrauma Research
  • Public Health Surveillance

Background:

  • Traumatic brain injury (TBI) is a significant concern in childhood, with mild TBI (mTBI) being the most common form.
  • Germany exhibits notably high hospitalization rates for pediatric TBI, potentially indicating over-admission for milder cases.
  • Understanding hospitalization trends and variability is crucial for optimizing pediatric TBI care.

Purpose of the Study:

  • To analyze trends in TBI-related hospitalizations for patients under 18 years old in Germany from 2014 to 2020.
  • To investigate the variability in TBI hospitalization rates across different pediatric emergency departments (EDs).

Main Methods:

  • A retrospective observational study utilizing the German Hospital Dataset (GHD).
  • Cases were identified using ICD-10 codes and severity was assessed using the Abbreviated Injury Scale (AIS) for head injuries.
  • Data from 18 participating pediatric EDs were analyzed to compare inpatient vs. outpatient management proportions.

Main Results:

  • A total of 618,577 TBI cases were analyzed, with annual hospitalizations decreasing from 91,299 in 2014-2019 to 70,783 in 2020.
  • Standardized morbidity ratios (SMRs) for all-cause and mTBI admissions significantly decreased in 2020 compared to the reference period.
  • Hospitalization rates varied widely across EDs, ranging from 19.1% to 93.0% (median 75.0%).

Conclusions:

  • The disproportionate decline in mTBI hospitalizations during the COVID-19 pandemic suggests a potential for increased outpatient management of mild TBI cases.
  • Variability in hospitalization practices highlights opportunities for standardizing care and improving resource allocation in pediatric TBI management.
