datetime
The frequency of consumption of alcohol by the participant.
integer
Date (and time, if applicable and known) the patient was admitted to the hospital
datetime
The date and time at which the patient was last known to be without the signs and symptoms of the current stroke or at his or her prior baseline. This element captures the date and time for last known well that is determined to be the most accurate after all the data have been evaluated and additional witnesses interviewed (if applicable).
datetime
Date (and time, if applicable and known) the Patient arrived at the hospital
datetime
Indicates whether the patient suffered a clinical stroke according to the following, "time-based" definition: Stroke is a sudden focal neurological deficit of presumed vascular origin lasting >= 24 hours (or fatal within 24 hours).
integer
Indicates whether the patient suffered a clinical stroke according to the following, "tissue-based" definition: Symptomatic stroke is a sudden focal neurological deficit, of any duration, due to focal brain, spinal cord, or retinal infarction or hemorrhage. Infarction or hemorrhage may be demonstrated either 1) directly by imaging/laboratory/pathologic examination in patients with symptom duration less than 24 hours, or 2) inferred by symptoms lasting >= 24 hours (or fatal within 24 hours) that cannot be attributed to another cause.
integer
Indicates the type of clinical stroke suffered by the adult patient, using duration of symptoms to distinguish between ischemic stroke and TIA.
integer
Indicates the type of clinical stroke suffered by the adult patient, using tissue status to distinguish between ischemic stroke and TIA.
integer
Date (and time, if applicable and known) the participant/subject was discharged from the hospital
datetime
The principal diagnosis is defined in the Uniform Hospital Discharge Data Set (UHDDS) as "that condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care."
text
Patient's discharge destination. The discharge destination is defined as where the patient is going for post-acute stay.
integer
Indicates whether Intravenous Tissue Plasminogen Activator (IV tPA) was initiated for the participant/subject at your hospital
integer
If Intravenous Tissue Plasminogen Activator (IV tPA) was initiated, indicates the date and time IV tPA was initiated at this hospital or ED (time of bolus administration)

integer
If intra-arterial (IA) procedure was initiated, describes the type of intra-arterial (IA) procedure performed on patient at this hospital
integer
Whether the participant/ subject received arterial dose anticoagulants during the acute hospital stay, not including venous prophylaxis dose Unfractionated heparin, LMW heparin, etc.
integer
Type(s) of anticoagulants received
integer

integer
Type(s) of antiplatelets received
integer
Antiplatelet other text

integer
Indicates if the participant/ subject received follow-up care from a stroke specialist.
integer
Indicates if the participant/ subject received follow-up care from a primary care physician (PCP).
