Data from: Factors related to time of stroke onset versus time of hospital arrival: A SITS registry-based study in an Egyptian Stroke Center

Background: high-quality data on time of stroke onset and time of hospital
arrival is required for proper evaluation of points of delay that might
hinder access to medical care after the onset of stroke symptoms. Purpose:
Based on (SITS Dataset) in Egyptian stroke patients, we aimed to explore
factors related to time of onset versus time of hospital arrival for acute
ischemic stroke (AIS). Material and Methods: We included 1,450 AIS
patients from two stroke centers of Ain Shams University, Cairo, Egypt. We
divided the day to four quarters and evaluated relationship between
different factors and time of stroke onset and time of hospital arrival.
The factors included: age, sex, duration from stroke onset to hospital
arrival, type of management, type of stroke (TOAST classification),
National Institute of Health Stroke Scale (NIHSS) on admission and
favorable outcome modified Rankin Scale (mRS ≤2).  Results:
Pre-hospital: highest stroke incidence was in the first and fourth
quarters. There was no significant difference in the mean age, sex, type
of stroke in relation to time of onset. NIHSS was significantly less in
onset in third quarter of the day. Percentage of patients who received
thrombolytic therapy was higher with onset in the first 2 quarters of the
day (p=<0.001). In-hospital: there was no difference in percentage
of patients who received thrombolytic therapy nor in outcome across 4
quarters of arrival to hospital. Conclusion: pre-hospital factors still
need adjustment to improve percentage of thrombolysis, while in-hospital
factors showed consistent performance.
