Research on dizziness-related impairment might provide options for a functional oriented approach with less focus on finding diagnoses. We therefore studied dizziness-related impairment in older primary care patients and aimed to identify indicators related to this impairment. Methods In a cross-sectional study we included 417 consecutive patients of 65 years and older presenting with dizziness to 45 general practitioners in the Netherlands from July 2006 to January 2008. We performed tests including patient history and physical and additional examination previously selected by an international expert panel and based on an earlier systematic review. Our primary outcome was impact of dizziness on everyday life measured with the Dutch validated version of the Dizziness Handicap Inventory DHI . After a bootstrap procedure 1500x we investigated predictability of DHI-scores with stepwise backward multiple linear and logistic regressions. Results DHI-scores varied from 0 to 88 maximum score 100 and 60 of patients experienced moderate or severe impact on everyday life due to dizziness. Indicators for dizziness-related impairment were onset of dizziness 6 months ago or more OR 95 CI frequency of dizziness at least daily OR 95 CI duration of dizziness episode one minute or less OR 95 CI presence of anxiety and or depressive disorder OR 95 CI use of sedative drugs OR 95 CI .
