[Fractures in the elderly: are postal questionnaires sufficiently sensitive?].
Within the European Prospective Osteoporosis Study the validity of a postal questionnaire concerning fractures in the elderly was assessed. A sample of 144 men and women aged 50 to 84 hospitalized in an urban hospital due to fractures within the past 12 months was investigated. Eight percent of the respondents denied any recent fracture and turned out to be false negatives, less than previously recorded. Mode and frequency of questioning seem to influence the results. To assess fracture localisation, we used a graphical method (mannequin). Due to various factors, one third of all localisations were incorrect.
