Implication

Diagnostic study demonstrates high negative predictive value of a stroke screening questionnaire in clinic outpatients, indicating its reliability for identifying stroke-free individuals.

Key Points

To evaluate the validity of the 8-item Questionnaire for Verifying Stroke-Free Status (QVSFS) against neurological history and physical examination in a population with high stroke prevalence.
Administered the 8-item QVSFS via research assistant to 155 outpatients from Veterans Administration stroke and general medicine clinics (mean age 70 years, 98.1% male).
Compared questionnaire results to independent neurological examinations performed by neurologists blinded to QVSFS responses to determine stroke-free status.
Neurological evaluation confirmed 78 of the 155 subjects were stroke-free.
The QVSFS demonstrated a negative predictive value of 0.96 and a positive predictive value of 0.71.
At least one question required rephrasing or clarification in 22 subjects (14.2%), with no single question requiring clarification more than 5 times.
