摘要Objective:To describe temporal changes associated with deployment of an optical character recognition(OCR)-enabled One-Identity(One-ID)digital platform for rural cervical cancer screening,focusing on over-screening rates,CIN2+detection,colposcopy follow-up,and CIN2+management.Methods:A multi-county pre-post observational study was conducted in six rural counties in Shanxi,Yunnan,and Sichuan Provinces(2021-2024),encompassing 153,978 encounters.The digital platform integrates OCR identity capture,deterministic One-ID linkage,and real-time duplicate alerts.Over-screening proportions before and after digital deployment were compared,changes in CIN2+detection rate were evaluated,and colposcopy follow-up and CIN2+management were assessed.Differences were tested with χ2 or Fisher's exact tests.Results:Among 153,978 encounters,the proportion of over-screening decreased from 12.64%in 2023 to 0.17%in 2024 with an absolute reduction of 12.17%(95%CI:11.94-12.40;P<0.001).The share of women receiving a first screening within the preceding 3 y increased from 78.3%to 88.2%(P<0.001).Colposcopy completion improved from 64.1%to 84.9%.The CIN2+detection rate rose from 0.35%(2021-2023 pooled)to 0.67%in 2024(P<0.001)and CIN2+management completion increased from 56.0%to 76.2%(95%CI:13.3-27.2;P<0.001).These improvements were consistent across age groups,counties,and screening strategies.Conclusions:The OCR-enabled One-ID platform substantially reduced over-screening,increased CIN2+detection rate,and strengthened case follow-up/management,particularly where baseline tracking was weak,supporting scalable digital reinforcement of rural screening programmes.
