When to Use the HINTS Examination in Patients With Dizziness: A Review.

HINTS is most diagnostically effective for acute vestibular syndrome patients with continuous dizziness and spontaneous nystagmus at rest, with accuracy dropping when used in inappropriate populations.

• Why it matters: Confusion about when to apply HINTS can contribute to diagnostic errors, including missed strokes or unnecessary imaging, because guidelines have not consistently defined key eligibility criteria.
• What they did: This review clarifies proper use by focusing on patient selection (continuous dizziness, spontaneous nystagmus at rest) and by highlighting common mistakes such as using HINTS without nystagmus or skipping central-feature screening.
• The result: When applied correctly, HINTS shows high sensitivity for detecting stroke, but diagnostic accuracy declines significantly in inappropriate patients, supporting clearer guidance and central-feature screening before testing.
