ObjectiveTo evaluate the performance of “Smartscopy” in diagnosing preinvasive cervical lesions among patients withabnormal cervical cancer screening results obtained during the coronavirus disease 2019 (COVID-19) pandemic. MethodsThis diagnostic study enrolled non-pregnant women with abnormal cervical cancer screening results obtained atthe colposcopy clinic at Srinagarind Hospital (Khon Kaen, Thailand) between September 2020 and March 2021. Twocolposcopists independently evaluated the uterine cervix using a smartphone and colposcopy. Cervical biopsies andendocervical curettage were performed in accordance with standard procedures. The diagnostic performance of asmartphone in detecting low-grade squamous intraepithelial lesions or worse plus (LSIL+) and high-grade squamousintraepithelial lesions plus (HSIL+) was assessed. ResultsIn 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, andaccuracy of the smartphone to detect LSIL+ were 96.6% (95% CI, 91.6-99.1), 12.9% (95% CI, 8.06-19.2), 46.2% (95%CI, 39.7-52.4), 83.3% (95% CI, 62.6-95.3), and 0.49% (95% CI, 0.43-0.55), respectively. The sensitivity, specificity, positivepredictive value, negative predictive value, and accuracy of smartscopy in diagnosing HSIL+ were 67.6% (95% CI, 55.2-78.5), 85.4% (95% CI, 79.9-90.0), 60.5% (95% CI, 48.6-71.6), 88.9% (95% CI, 83.7-92.9), and 81.0% (95% CI, 0.75-0.85),respectively. ConclusionSmartscopy demonstrated a remarkable correlation with colposcopy and a high diagnostic performance value for thedetection of preinvasive cervical lesions. Therefore, smartscopy may be an alternative tool for detecting abnormalcervical lesions in low to medium medical resource settings. Smartscopy may be applied in telemedicine during theCOVID-19 pandemic.
