Secondary Prevention of Childhood Arterial Ischemic Stroke

Area of Science:

• Pediatric Neurology
• Cardiovascular Research
• Clinical Trial Design

Background:

• Secondary prevention of childhood arterial ischemic stroke (AIS) is crucial.
• Current guidelines exist, but physician adherence and perspectives on new trials are not well understood.
• Understanding physician practices is key to improving pediatric stroke care.

Purpose of the Study:

• To evaluate guideline implementation for secondary stroke prevention in children across France, Belgium, and Switzerland.
• To gather frontline physicians' views on a potential clinical trial for aspirin's preventive efficacy in pediatric stroke.
• To identify factors influencing physician acceptance of clinical trial designs.

Main Methods:

• Online survey distributed to pediatric specialists via dedicated networks.
• Mixed-methods approach for comprehensive data analysis.
• Data collected from 63 responding physicians.

Main Results:

• 88% of physicians prescribe aspirin for secondary stroke prevention in children, excluding specific conditions like sickle cell disease, cardio-embolic stroke, and cervical artery dissection.
• Prescribing practices show variation based on physician specialty.
• A majority of physicians favor placebo or historical controls for comparison in a clinical trial against an aspirin arm.

Conclusions:

• Physicians in the studied European countries demonstrate good adherence to existing guidelines for secondary prevention of childhood stroke.
• A clinical trial investigating aspirin's efficacy could gain physician acceptance, provided specific study design elements are addressed.
• Further research and physician input are essential for optimizing pediatric stroke prevention strategies and clinical trial development.
