Summary
Prehospital delays in recurrent Acute Ischemic Stroke (AIS) are common, similar to first-time AIS. Lack of stroke knowledge and living situation significantly impact these delays, necessitating targeted public health education.
Area of Science:
- Neurology
- Public Health
- Emergency Medicine
Background:
- Prehospital delays in Acute Ischemic Stroke (AIS) impact patient outcomes.
- Understanding factors contributing to delays in recurrent AIS is crucial for timely intervention.
Purpose of the Study:
- To investigate prehospital delays in recurrent AIS patients.
- To identify key factors contributing to these delays.
- To inform targeted interventions for improving stroke response times.
Main Methods:
- Retrospective cohort analysis of 1419 AIS patients (December 2021 - August 2023).
- Utilized Extreme Gradient Boosting (XGBoost) and SHapley Additive exPlanations (SHAP) for determinant analysis.
Main Results:
- Living situation and stroke knowledge deficits are significant risk factors for delayed hospital presentation in recurrent AIS.
- Key influencing factors include residential status, symptom awareness, comorbidities (diabetes, coronary artery disease), and stroke type.
Conclusions:
- Prehospital delay patterns in recurrent AIS are comparable to first-time AIS, indicating a knowledge gap.
- Enhanced stroke education and public health initiatives are essential to reduce delays and improve outcomes for all AIS patients.
