Follow-up of abnormal results is essential to cervical cancer screening, but data on adherence to follow-up are limited. We describe patterns of follow-up after screening abnormalities and identify predictors of guideline-concordant follow-up. We identified the index screening abnormality (positive human papillomavirus [HPV] test or atypical squamous cells of undetermined significance [ASC-US] or more severe cytology) among women 25-65 years old at three U.S. healthcare systems during 2010-2019. We estimated the cumulative incidence of surveillance testing, colposcopy, or treatment after the index abnormality and initial colposcopy. Logistic regressions were fit to identify predictors of guideline-concordant follow-up according to contemporaneous guidelines. Among 43,007 patients with an index abnormality, the cumulative incidence of any follow-up was 49.6% by 4 years for those with ASC-US/HPV-negative and higher for abnormalities warranting immediate colposcopy. The 1-year cumulative incidence of any follow-up after colposcopy was 70% for patients with normal results or cervical intraepithelial neoplasia (CIN) I and 90% for patients with CIN II+. Rates of concordant follow-up after screening and colposcopy were 52% and 47%. Discordant follow-up was associated with factors including age, race/ethnicity, overweight/obese BMI, and specific types of public payor coverage or being uninsured. Adherence to recommended follow-up of cytologic and histopathologic abnormalities is inconsistent in clinical practice. Concordance was poor for mild abnormalities and improved, though suboptimal, for more severe abnormalities. There remain gaps in the cervical cancer screening process in clinical practice. Further work is needed to understand barriers to appropriate management of cervical abnormalities.
