Analyze the efficiency of the implementation of the colposcopy and cervico-vaginal pathology quality charter. The question was to determine whether the criteria of more than 70% of excisional conizations containing CIN2+ lesions (cervical intraepithelial neoplasia 2 or 3 or carcinoma in situ) had been reached and demonstrate a reduction of the conization rate is possible. An epidemiological descriptive, retrospective and multicenter study was performed in "Nord Franche-Comté Hospitals" (Belfort and Montbéliard, France) during the period from November 2013 to January 2015. Inclusion criteria were patients over 25 years undergoing cervical excisions for diagnostic and/or therapeutic purposes after Pap smear screening followed by colposcopically directed biopsies. The files were selected from a data collection and studied using the computerized patient record. In total, 116 conizations were performed: 103 by four French Society of Colposcopy and Cervico-Vaginal Pathology (SFCPCV) members and 13 by four SFCPCV non-members. The overall result of the primary outcome showed 53% of CIN2+ lesions found in cervical conization specimens, which can be broken down to 55% for the group of SFCPCV members and to 38% for the group of SFCPCV non-members. The statistical analysis indicates a significant difference (P=0.02) in the percentage of CIN2+ lesions discovered on the surgical specimen for the group of SFCPCV members. This self-evaluation shows that it is essential to be a SFCPCV member and to adhere to the charter. By complying with the charter and associating the new National Cancer Institute recommendations (December 2016), it is possible to reduce the conization rate and even to surpass the target of more than 70% of excisional conizations containing CIN2+ lesions.
