SAMELLI, Alessandra Giannella et al. Comparing audiological evaluation and screening: a study on presbycusis. Braz. j. otorhinolaryngol. (Impr.) [online]. 2011, vol.77, n.1, pp. 70-76. ISSN 1808-8694.  http://dx.doi.org/10.1590/S1808-86942011000100012.

Given the high prevalence of presbycusis and the damage it brings about, a screening test can be useful in the identification of hearing loss in primary care. AIM: To estimate the prevalence of hearing loss in a representative sample of elderly people living at Butantan using an audiological screening method (questionnaire) and a basic audiological evaluation; to compare the results of the two kinds of evaluations, checking the validity of this tool for hearing loss screening. DESIGN: Cross sectional descriptive study. MATERIALS AND METHODS: 200 individuals (above 60 years old, both genders) were randomly selected to undergo audiological screening (questionnaire). Another randomly selected group encompassed 100 individuals who were submitted to a set of audiological tests. Then, we compared the results from the two methods. RESULTS: There were no statistically significant associations between the questionnaire and the degree of hearing loss of the patients. CONCLUSION: The prevalence of hearing loss in our sample was of 56% in the screening and of 95% when checked by the audiological evaluation. Therefore, screening was not proven valid to assess hearing when compared to audiological evaluation.
