Observed Colposcopy Practice in US Community-Based Clinics: The Retrospective Control Arm of the IMPROVE-COLPO Study

In this analysis, most colposcopists performed few colposcopies and took less than 2 biopsies per patient. Colposcopic impression had a poor sensitivity to predict histology-confirmed CIN 2+. Although recent research indicates that taking multiple biopsies improves sensitivity and detection of CIN 2+, this is not being practiced in the US.
