목적: The patients who are actually buying hearing aids are less than 50% among the patients with moderate or severe hearing loss. Clinically, patients with low speech discrimination or severe high frequency hearing loss are more difficult to be satisfied with hearing aids. The purpose of this study is to investigate the buying rate according to possible related factors. Especially we are interested in the configuration of hearing loss is related to the purchase. 방법:151 patients who had hearing aids consultation because of hearing loss from September to December 2014 were enrolled in this study. We retrospectively reviewed medical records of these patients. The patients were divided into 2 groups according to actual purchase of hearing aids. We analyzed factors affecting actual purchase between these 2 groups. The configuration of audiogram was classified 6 categories according to Pittman and Stelmachowicz(2003), which is sloping, rising, flat, U-shaped, tent-shaped and other. And we picked patients who had steeply sloping hearing audiogram and analyzed with purchase or not. 결과:Among total of 151 patients, 44 patients bought hearing aids and 107 patients did not buy hearing aids. There was no statistically significant difference in the configuration of audiogram between 2 groups. The pure tone average of buying-group was 61.3 dB and which was significantly higher than non-buying group patients(Independent T-test, P<0.05). Among 100 patients with sloping configuration of audiogram, 57 patients’ audiograms were steeply sloping in configuration and these patients were categorized ski-slope group. The ski-slope group patients had lower buying rate 21.1% of hearing aids comparing non-ski-slope group(34.0%). 결론:In conclusion, patients who bought hearing aids had more hearing loss than the others. And the patients who had audiogram with steeply sloping configuration were less likely to buy hearing aids.
