Background: Digital cytopathology (DC) is emerging as a transformative approach in quality assurance programs (QAP), though its comprehensive evaluation remains limited. Since 2020, the Korean Society for Cytopathology has progressively incorporated DC into its national QAP, including digital proficiency testing (PT), sample adequacy testing (SAT), a customizable PT module, and a self-assessment module (SAM), aiming for full digital implementation by 2026. Methods: This 5-year study assessed diagnostic concordance between conventional and digital PT formats and analyzed participant feedback on service quality and digital image usability across PT, SAT, and SAM. Parallel testing was conducted during the transitional phase, and satisfaction was measured through structured surveys. Results: Participation in digital PT increased from 48 institutions in 2020 to 93 in 2024, while digital SAT participation rose from 29 to 71 between 2022 and 2024. In 2023, 56 institutions joined SAM. Diagnostic concordance rates were comparable between digital and conventional PTs (78.6%–84.6% vs. 82.0%–85.1%), including similar category C (major discordance) rates. Satisfaction with digital PT services and image quality exceeded 85%, and over 90% of institutions reported positive feedback on SAT and SAM. Over 80% were satisfied with the customizable PT module. Conclusions: DC is a reliable and effective modality for cytopathology QAP. It demonstrates diagnostic equivalence to conventional methods and high user satisfaction, supporting its broader implementation in national quality assurance frameworks.
