Objective: The aim of this study was to evaluate the 100% rapid review (100%-RR) as an effective tool for internal quality control (IQC) in gynecological cytopathology services. Study Design: A total of 8,677 swabs were analyzed; the negative results were submitted to 100%-RR. Divergent cases were discussed in a consensus meeting to reach a conclusion on the final diagnosis. The data were entered into SAS statistical software, and the agreement of the 100%-RR results with the final diagnosis was tested with the weighted kappa statistic. Results: Of the 8,155 smears characterized as negative, 255 (3.13%) were abnormal smears, and 552 (6.77%) unsatisfactory smears were deemed negative. Regarding the results on the 8,155 smears subjected to 100%-RR when compared with the final diagnosis, there was agreement in 7,063 (86.60%) of them, and there were 1,092 (13.40%) discordant results (65.6%, unsatisfactory; 5.47%, atypical squamous cells of undetermined significance [ASC-US]). The κ index had an agreement of 0.867, with κ = 0.734 (p < 0.0001). Compared with the final diagnosis, the sensitivity of 100%-RR was 99.91% and its specificity was 99.4% for severe abnormalities. The sensitivity for high-grade squamous intraepithelial lesions was 88.2%, with a specificity of 100.00%. For abnormalities considered borderline, such as ASC-US, the sensitivity was 94.50% and the specificity was 99.5%. Conclusion: The 100%-RR was considered efficient when used as an IQC method.
