The CASES-TCM study is a prospective, multicenter, observational study, which will enroll 20,000 patients with acute stroke (ischemic stroke or intracerebral hemorrhage) within 7 days of symptom onset.
This study attempts to depict major clinical characteristics of acute stroke in patients with Chinese medicine treatment and to explore any difference compared with other non-Chinese medicine use cohorts and the effectiveness and safety of Chinese medicine.

Chinese medicine treatment duration will be assessed using proportion of days covered, which is a percentage of days covered with the medicine in the number of days the patient is eligible to have the medication. |
| 3 months, 12 months, and 24 months follow-up |
| Change in the National Institutes of Health Stroke Scale score between baseline (admission) and discharge | National Institute of Health Stroke Scale is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. It is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0. | At admission (baseline) and discharge (14 days - mean for length of hospitalization for stroke patients) |
| Patient-Reported Outcomes Scale for Stroke score at discharge | Patient-Reported Outcomes Scale for Stroke, a structured questionnaire-scale was developed suitable for Chinese patients. The score ranges from 0 (best) to 144 (worst). | At discharge (14 days - mean for length of hospitalization for stroke patients) |
| Proportion of patients with modified Rankin Scale score ≤2 at 3-month and 12-month follow-up | Modified Rankin Scale, a commonly used scale for measuring the degree of dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. 0 - No symptoms.1 -No significant disability. Able to carry out all usual activities, despite some symptoms.2 - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.3 - Moderate disability. Requires some help, but able to walk unassisted.4 - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.5 - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.6 - Dead. | 3 months, 12 months follow-up |
| Distribution of scores on the modified Rankin scale at 12-month follow-up | Modified Rankin Scale, a commonly used scale for measuring the degree of dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. 0 - No symptoms.1 -No significant disability. Able to carry out all usual activities, despite some symptoms.2 - Slight disability.

| Proportion of patients with Barthel Index score ≥90 at 3-month and 12-month follow-up | Barthel Index is a commonly used scale for measuring the activity of daily living of people. Score of 10-item scale ranges from 0 (worst) to 100 (best). | 3 months, 12 months follow-up |

| Composite of new clinical vascular events within 3-month, 12-month, and 24-month follow-up | Number of patients with new clinical vascular events (ischemic stroke/ hemorrhagic stroke/ transient ischemic attack / myocardial infarction /vascular death) within 3 months, 12 months, and 24 months of follow-up. | 3 months, 12 months, 24 months follow-up |
| Mini-Mental State Examination scale score at 3-month, 12-month, and 24-month follow-up | Mini-Mental State Examination scale is a commonly used scale for measuring the cognitive function. Range: 0 to 30 points, higher points represent a better outcome. | 3 months, 12 months, 24 months follow-up |
