Background
Vertigo, defined as an illusion of rotatory motion, is a common symptom that is generally disabling and usually requires medical assistance. Yet, few epidemiological studies have been conducted to analyse the epidemiology of vertigo in the general population. This sort of studies are best carried out in primary healthcare centres, since patients usually seek attention from their family doctor at some point.
The objective is to analyse the annual incidence of patients with vertigo in the Autonomic Region of Valencia through the primary healthcare routine information system.
Methods
This is an observational retrospective analysis of the annual incidence of vertigo in the Autonomic Region of Valencia during the period January 2004 to September 2009. The catchment population comprises 6 728 630 adults.
Data were obtained through the primary healthcare routine information system Abucasis. Annual incidence was computed as cases of patients per 1 000 inhabitants per year, based on two ICD-9-CM codes: Dizziness and giddiness (ICD 780.4) and Vestibular vertigo (ICD 386).
Results
A total of 14 207 patients were attended annually due to vestibular vertigo (2.1 per 1 000 inhabitants per year) and 89 543 patients due to dizziness and giddiness (13.3 per 1 000 inhabitants per year).
Annual incidence is two times higher among women than among men for both codes. There is a progressive increase of annual incidence with age, and it is highest for the interval ?76-85 years?. Differences between Primary Health Departments are relatively important.
Conclusions
A prospective study was conducted in the same region and it found an annual incidence of vestibular vertigo of 17.8 patients per 1 000 inhabitants per year, a figure that is higher than the results obtained in this study. Other studies suggest that vestibular vertigo accounts for a considerable percentage of the burden of dizziness and giddiness. This discrepancy might be due to deficiencies in the anamnesis and conduct of diagnostic and therapeutic manoeuvres by primary care physicians, with a subsequent underdiagnosis and inadequate management of vestibular vertigo. Thus, we recommend boosting training on this pathology as well as an adequate communication with otoneurology services.
