Numbers shown represent patients eligible for each measure. AF indicates atrial fibrillation; BI, brain imaging; DTN, door‐to‐needle time; DVT, deep vein prophylaxis; IV, intravenous; ND, not documented; PAA, Performance Achievement Award; PSC, Primary Stroke Center; TPA, tissue‐type plasminogen activator.

P values are based on Pearson χ² tests for all categorical row variables. All tests treat the column variable as nominal. See Methods section for each stroke measure and summary measures definitions.
