Insights

Intravenous thrombolysis (IV-tPA) and mechanical thrombectomy (MT) use for pediatric acute ischemic stroke (AIS) increased in the US from 2009-2019, primarily in older children and non-children's hospitals.

Area of Science:

  • Pediatric Neurology
  • Stroke Medicine
  • Health Services Research

Background:

  • Acute ischemic stroke (AIS) in children is a rare but serious condition.
  • Intravenous thrombolysis (IV-tPA) and mechanical thrombectomy (MT) are established treatments for AIS in adults.
  • Data on the utilization trends of these treatments in pediatric populations are limited.

Purpose of the Study:

  • To evaluate current trends in the utilization of IV-tPA and MT for pediatric AIS in the United States.
  • To analyze age-specific utilization patterns and demographic predictors of treatment.

Main Methods:

  • Serial cross-sectional study using the 2009-2019 KIDS Inpatient Database.
  • Analysis of primary AIS admissions in children aged 0-17 years (n=2807).
  • Calculation of age-specific utilization frequencies and multivariable-adjusted models for demographic predictors.

Main Results:

  • IV-tPA utilization nearly tripled (2.5% to 6.5%) and MT use more than doubled (1.2% to 3.0%) from 2009 to 2019.
  • Increased utilization was most prominent in older children (10-17 years) and in non-children's hospitals.
  • Utilization rates in younger children and in dedicated children's hospitals remained largely unchanged.

Conclusions:

  • Pediatric AIS treatment with IV-tPA and MT has increased significantly over the past decade in the US.
  • This increase is mainly observed in older children and in non-pediatric specialized centers.
  • Further research is needed to understand the implications of these trends on outcomes in pediatric stroke patients.
