The rapid bedside triple test shows high accuracy in predicting vertigo, correlating well with the standard caloric test. This makes it a reliable tool for quick clinical diagnosis in ENT clinics.
Area of Science:
- Otolaryngology
- Neurology
- Vestibular System Diagnostics
Background:
- Vertigo is a common presenting complaint in otolaryngology and neurology.
- Accurate diagnosis of vertigo requires reliable vestibular testing.
- The caloric test is a standard but time-consuming diagnostic method.
Purpose of the Study:
- To evaluate the diagnostic correlation between the rapid bedside triple test and the established caloric test.
- To determine the clinical utility of the bedside triple test as a screening tool for vertigo.
Main Methods:
- Retrospective review of 313 consecutive vertigo patient records from an ENT clinic.
- Comparison of bedside triple test results with caloric test outcomes.
- Calculation of sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV).
Main Results:
- The bedside triple test demonstrated a sensitivity of 65.1% and specificity of 94.0%.
- Positive predictive value (PPV) was 90.5%, and negative predictive value (NPV) was 75.5%.
- These results indicate a strong agreement between the triple test and caloric test.
Conclusions:
- The rapid bedside triple test is a highly specific and reliable tool for the clinical diagnosis of vertigo.
- It serves as an effective and rapid screening method in ENT practice.
- The triple test offers a valuable alternative for quick vestibular assessment.
