This study will assess the sensitivity and specificity of the bedside examination algorithm performed by ED physicians. Finally, it aims to identify predictors of a central cause of the symptoms. This will consequently reduce the rate of misdiagnosis as well as the costs and length of stay due to inappropriate neuroimaging.
Patients presenting at the ED with vertigo, dizziness or unsteadiness
>= 18 years of age
Patients able to give their consent
Patients with dementia
Bedridden patients (for causes other than the current symptoms)
Patients with obvious neurological findings presenting with vertigo but with suspected stroke at triage
Patients presenting at the ED with vertigo, dizziness or unsteadiness
Case-only
Cross-sectional
Bedside examination of Vertigo
Diagnostic testED visit comprehensive of bedside examination of vertigo performed by trained EP or emergency medicine residents
The AUC of the bedside examination algorithm performed by ED physicians
identification of predictors of true positive patients
Predictors of true positive patients can help to stratify patients with vertigo for the risk of stroke.
evaluation of number of neuroimaging tests (TC and angio-TC) performed to patients with vertigo in the ED.tests performed
to study the use of ED resources for these patients in terms of number of neuroimaging tests performed.
