목적: To compare the effectiveness of Ballpen click test with an mHealth mobile application (hearWHO), using the 40-score cut off, in screening for hearing loss among school-age children in a community setting. 방법:This was the phase 3 of a cross sectional study involving a subpopulation of 85 school-age children, enrolled in a government 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 -12 years old were randomly selected and subjected to hearing tests using the ballpen click test as index test, and pure tone audiometry as reference test. Results were compared with the outcomes of our phase 2 study, where hearWHO as the index test was performed in the subset of 83 students from the same study population. 결과:In the 170 ears tested, Ballpen click test demonstrated higher specificity with an average of 90.59+/-3.93%, compared to the 166 ears screen using hearWHO app resulting to specificity of 60.97+/-11.09%. Sensitivity percentage between the two index test cannot be compared since two subgroups in the ballpen click test registered normal hearing for both the test and pure tone audiometry. The Kappa statistic indicated poor agreement with pure tone audiometry for both methods- 0.108 for ballpen click and 0.091 for hearWHO 결론:Ballpen click test can effectively specify those with hearing loss and predict the true negatives among the school age children in our study population, compared to hearWHO, using the 40-score cut off which is sensitive to identify those without hearing loss as students increase their grade levels. However, both tests outcomes have poor agreement with pure tone audiometry, utilized as reference test in our study.
