Clinical stroke time-based definition indicator
ClinStrokeTimeBasedDefinInd

Regarding the "Core" classification for this element: A clinical study should at a minimum use either the "time-based" or the "tissue-based" definition for clinical stroke. Some clinical studies may find it appropriate to use both definitions.

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.

The "NINDS Stroke Common Data Element (CDE) Project, Stroke Types and Subtypes Subgroup: Recommendations" has detailed definitions for each stroke type. That document also suggests using a term like "Acute Neurovascular Syndrome" for patients with relatively brief symptom duration (e.g., symptoms that persist several hours but less than a day), who do not receive a detailed diagnostic imaging evaluation and thus it is not possible to determine whether stroke or TIA is the most appropriate diagnosis.

Trace amount of blood or mild bleeding;< Half of the ventricle filled with blood;> Half of the ventricle filled with blood;Ventricle expanded and filled with blood;
Numeric values
Contains data elements collected when an imaging study is performed to measure parenchyma; data recorded attempt to divide the strokes into ischemic or hemorrhagic subtypes, as distinction of hemorrhage versus infarction is the initial critical branch point in acute stroke triage. (Examples of CDEs included: Acute infarcts present; Planimetic acute ischemic lesion volume; and Acute hematoma present)
