ENGLISH SUMMARY
Objectives: The aim of this study was to evaluate the extent and quality
of work-up of dizzy patients at the Landspitali Emergency department.
Patients and methods: All cases presenting to the emergency depart-
ment with the main complaint of dizziness over a period of four months
were analyzed retrospectively. Demographics, duration of symptoms,
diagnosis and results from investigations and consultations were
recorded from medical records. Investigations were categorized to
blood tests, brain imaging and consultations to simplify interpretation of
the results.
Results: One hundred sixty three cases were identified. 28% were
diagnosed with inner ear problem and 32% were discharged without
diagnosis. A serious central nervous system cause was found in 4% of
cases. About one-third underwent investigations from all of the three
investigation categories. An acute CT scan of the brain was obtained
in 40% and MRI in 17% of all cases. Consultation was obtained from a
neurologist for 28%, ENT for 26% and a cardiologist for 2% of cases.
11.6% (n=19) of the patients were admitted to the hospital, 53% to
neurology, 42% to internal medicine and 5% to ENT.
Conclusions: Dizziness is a common complaint in the emergency
department and the cause is most often benign. Nevertheless, patients
with dizziness routinely undergo extensive workup which often includes
acute CT scan of the brain.
Dizziness in the emergency department – do we lack clinical judgment?
