ObjectiveTo evaluate the performance of "Smartscopy" in diagnosing preinvasive cervical lesions among patients with abnormal cervical cancer screening results obtained during the coronavirus disease 2019 pandemic. MethodsThis diagnostic study enrolled non-pregnant women with abnormal cervical cancer screening results obtained at the colposcopy clinic at Srinagarind Hospital (Khon Kaen, Thailand) between September 2020 and March 2021. Two colposcopists independently evaluated the uterine cervix using a smartphone and colposcopy. Cervical biopsies and endocervical curettage were performed in accordance with standard procedures. The diagnostic performance of a smartphone in detecting lowgrade squamous intraepithelial lesions or worse (LSIL+) and high-grade squamous intraepithelial lesions (HSIL+) was assessed.Results: In total, 247 patients were included. There was high agreement between the two colposcopists (κ=0.88; 95% confidence interval [CI], 0.82-0.93). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the smartphone to detect LSIL+ were 96.6%
