A community educational program and the introduction of a colposcope in Decatur, Alabama, led to a dramatic decrease in the relative percent of patients evaluated by conization after a positive Pap smear, and a corresponding increase in the relative percent of colposcopic evaluations. The percent of negative or dysplastic tissue diagnoses from conization was reduced from 78% before the colposcopy program to 61% after the program. It was estimated that the colposcopy program resulted in an 81% reduction in the number of conizations and that colposcopy used in lieu of conization resulted in a substantial reduction in both morbidity and cost.
阿拉巴马州迪凯特的一项社区教育计划以及阴道镜的引入，使得巴氏涂片检查呈阳性后接受锥形切除术评估的患者相对百分比大幅下降，同时阴道镜评估的相对百分比相应增加。锥形切除术诊断出的阴性或发育异常组织的百分比从阴道镜检查计划实施前的78%降至计划实施后的61%。据估计，阴道镜检查计划使锥形切除术的数量减少了81%，用阴道镜检查代替锥形切除术可大幅降低发病率和成本。
