목적: To determine the cut-off points of a mHealth mobile hearing screening application scores in predicting hearing loss in community setting among school-age children 방법:This was the phase II of a cross-sectional study involving a subpopulation of eighty-three school-aged children, enrolled in an urban government run school, conducted during the ear and hearing care advocacy activity of the Philippine Academy of Audiology, from January 13, 2024 to May 11, 2024. Eligible students aged 7 to 12 years old were randomly selected and subjected to hearing tests using the mHealth mobile hearing screening application, hearWHO, as the index, test followed by pure tone air conduction audiometry as the reference test. One hundred sixty-six ear scores from the application for hearing screening and corresponding pure tone averages were analyzed via diagnostic accuracy and receiver operating characteristic curve determination. 결과:On the evaluation of 166 ears, the mHealth hearing screening mobile application, hearWHO, has high sensitivity, and NPV in cut off points at 40, 50 and 70, when used in all grade levels particularly among those in Grade 5 and 6 levels . In the ROC analysis showed that the <40 cut off score showed better ability to distinguished those with hearing loss in this study population with a Youden index of 0.226 compared to other scores. However, the resulting area under the curve of .566 (95% Confidence Interval: 0.347 0.741). 결론:The mHealth hearing screening mobile application, hearWHO, can predict absence of hearing loss with high sensitivity and high negative predictive values using scores of 50 and 70 as arbitrary cut off points. However, optimal cut off points remained undetermined in our study population based on ROC analysis. Hence limitations identified must be addressed when conducting further studies regarding the applications cut off points in detecting the condition in this age group.
