Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	All-cause mortality during hospitalization	analyzed for patients in Group 1 and Group 2	up to 3 months
Secondary	Proportion of patients with hemorrhagic stroke during hospitalization	analyzed for patients in Group 1 and Group 2	up to 3 months
Secondary	Change of National Institutes of Health Stroke Scale (NIHSS) score from before IV rt-PA treatment to 24 hours after IV rt-PA treatment	analyzed for patients in Group 1 and Group 2 The NIHSS is a 15-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss.; NIHSS scores range from 0 - 42. A score of 0 indicates no stroke symptoms. Higher scores indicate incremental levels of neurological impairment.	baseline and 24 after IV rt-PA treatment
Secondary	modified Rankin Scale (mRS) score at discharge	analyzed for patients in Group 1 and Group 2 The modified Rankin Scale (mRS) is used for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability.; The scale runs from 0-6, from 'perfect health without symptoms' to 'death'. 0 - No symptoms.; - No significant disability. Able to carry out all usual activities, despite some symptoms.; - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.; - Moderate disability. Requires some help, but able to walk unassisted.; - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.; - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.; - Dead.	up to 3 months
Secondary	Proportion of patients with stroke recurrence during hospitalization	analyzed for patients in Group 1 and Group 2	up to 3 months
Secondary	Length of hospitalization	analyzed for patients in Group 1 and Group 2	up to 3 months
Secondary	Percentage of IV rt-PA treatment among AIS patients arrived or were admitted to the hospital within 4.5 hours of symptom onset	The percentage of IV rt-PA treatment will be calculated based on age groups (18-80 years and >80 years).	up to 3 months
Secondary	Percentage of IV rt-PA treatment within 4.5 hours of symptom onset among eligible AIS patients (3.5-hour arrival or admission)	The percentage of IV rt-PA treatment will be calculated based on age groups (18-80 years and >80 years).	up to 3 months
