The Potential of a Portable, Sound-isolating Device for hearing loss Screening in Low- and Middle-income Countries
INTRODUCTION: An estimated 278 million people worldwide suffer from bilateral moderate to profound hearing loss. Approximately 80% of this population lives in low- or middle- income countries, where access to formal audiologic testing remains a significant challenge, both from an economic and geographic standpoint. In order to addres this issue, screening devices that are not only sensitive, but mobile and affordable as well, must be employed.
METHODS: In February, 2017, a population of 49 elementary-school aged children in Jinotega, Nicaragua were enrolled for audiologic screening using a sound-isolating headset. The headset was driven by a tablet running an application designed to produce pure tones. For each subject, a 1,000, 2,000, and 3,000 Hz tone was played at a standardized intensity of 20 dB. A referral for any pitch in either ear was considered a failed screen. Subjects who failed subsequently underwent formal audiologic evaluation in a sound-isolating booth. Prior to screening, each subject underwent an otoscopic evaluation.
RESULTS: The final study population consisted of 47 subjects. Ages ranged from 5-7 years old. Nine subjects failed the screening exam while the remaining 38 passed. Of the 9 failed subjects, formal audiogram showed 6 subjects to have normal hearing at the aforementioned frequencies at 20 dB. Two subjects were found to have clinically-significant hearing loss. The results of one subject are pending.
CONCLUSION: Our study demonstrates the utility of a low-cost, portable device that can efficiently and effectively screen for hearing loss; however, more information is needed to understand the full screening potential. Subjects who pass the screening should be tested with the gold-standard (formal audiologic testing in a sound-isolating booth), as well. This would provide information on sensitivity and negative predictive value, both of which are important for the assessment of a devices screening utility.
- Realize the potential of affordable, easily-mobile devices for hearing-loss screening
- Observe how such a device adequately identified hearing loss in some subjects
- Understand the type of data that is needed to evaluate the utility of such devices
