Brief Summary

Ischemic cerebrovascular diseases originating from the brain's posterior circulation account for 20-25% of cases. Among patients diagnosed with cerebellar infarction, 10% present with isolated dizziness as their sole symptom. Notably, posterior circulation strokes and cerebellar infarcts are misdiagnosed 2 to 4 times more frequently than anterior circulation strokes. In 2017, Kuroda et al. developed the TriAGE+ score to assess stroke risk in patients presenting with dizziness. This study aims to externally validate the TriAGE+ score, focusing on its safety, applicability, and reliability in predicting cerebrovascular disease in the emergency department.

Conditions

Stroke, Ischemic

Keywords

Triage+; Cerebrovascular Accident; Dizzyness; Neurologic Deficits

Outcome Measures

Primary Outcomes (1)

• Stroke

  The outcome for this study was the occurrence of stroke, defined as a new sudden neurological deficit of vascular origin.

  30 days (patient will be followed up 30 days based on their initial visit with dizziness. During the 30-day period, any subsequent visits to relevant specialities or the emergency department will be reviewed to assess for a stroke diagnosis.)

Study Arms (1)

Patients with dizziness

Individuals aged 18 years and over who present to the emergency department with dizziness will be assessed using the TriAGE+ score.

Diagnostic Test: Triage+ Score

Interventions

Triage+ Score DIAGNOSTIC_TEST

The TriAGE+ score is used to evaluate the risk of cerebrovascular disease in patients presenting with dizziness. The score assists in determining the necessity of advanced diagnostic evaluation for stroke, potentially improving diagnostic accuracy and patient outcomes.

Patients with dizziness

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study will include adult (\>18 years old) patients presenting to the emergency department with dizziness. These patients must provide informed consent, or consent must be obtained from their legal guardians if the patients are unable to do so. This population will serve as the basis for externally validating the TriAGE+ score, developed in Japan, in a Turkish emergency department setting.

You may qualify if:

• Patients with dizziness who presented to the emergency department
• Patients who provide informed consent, or legal guardians providing consent for patients unable to do so.

You may not qualify if:

• Patients whose primary symptom is syncope or presyncope, or who present with dizziness due to hemodynamic compromise from gastrointestinal bleeding or other major events.
• Patients under the influence of alcohol or substances.
• Pregnant patients.
• Patients previously included in the study.
• Patients who refuse medical treatment or withdraw consent.
• Patients with incomplete data necessary for the study.
