The “HINTS” (Head Impulse, Nystagmus, Test of Skew) eye movement battery had high sensitivity 95.3% (95% CI 92.5-98.1) and specificity 92.6% (88.6-96.5). WebbObjectives: Dizziness and vertigo account for about 4 million emergency department (ED) visits annually in the United States, and some 160,000 to 240,000 (4% to 6%) have cerebrovascular causes. Stroke diagnosis in ED patients with vertigo/dizziness is challenging because the majority have no obvious focal neurologic signs at initial …

Webb15 okt. 2013 · HINTS sensitivity for stroke was 96.5% (n = 109 of 113) with a specificity of 84.4% (n = 65 of 77; LR+ = 6.19, LR– = 0.04). HINTS correctly identified the 11 central, nonstroke cases, which lowered the test's specificity for stroke, per se, but raised it when considering central causes.
