## Description

### **Background**

High-quality data on time of **stroke onset** and **hospital arrival** is critical for evaluating delays in accessing medical care after the onset of stroke symptoms.

### **Purpose**

Using the **SITS dataset** for Egyptian stroke patients, this study explores the relationship between:

- Time of stroke onset

- Time of hospital arrival  

... and other relevant clinical and demographic factors.

### **Material and Methods**

- **Patients:** 1,450 acute ischemic stroke (AIS) patients  

- **Centers:** Two stroke centers at Ain Shams University, Cairo, Egypt  

- **Time Analysis:** The day was divided into four quarters  

- **Factors Studied:**

  - Age  

  - Sex  

  - Duration from stroke onset to hospital arrival  

  - Type of management  

  - Type of stroke (TOAST classification)  

  - NIHSS on admission  

  - Favorable outcome (mRS ≤ 2)

### **Results**

#### *Pre-Hospital Findings:*

- **Highest stroke incidence** was observed in the **first and fourth quarters** of the day.

- No significant difference in:

  - Mean age  

  - Sex  

  - Type of stroke across different onset times  

- **NIHSS scores** were significantly lower for strokes starting in the **third quarter** of the day.

- **Thrombolytic therapy** was more common in strokes that occurred during the **first two quarters** of the day (*p < 0.001*).

#### *In-Hospital Findings:*

- No significant difference in:

  - Percentage of patients receiving thrombolysis  

  - Outcome measures across the four quarters of **hospital arrival**

### **Conclusion**

- **Pre-hospital delays** remain a barrier to receiving timely thrombolysis.

- **In-hospital performance** showed consistency regardless of time of arrival.
