Analysis of the performance of 100% rapid review using an average time of 1 and 2 minutes according to the quality of cervical cytology specimens Objectives: To compare the performance of the 100% rapid review method carried out in a mean time of either 1 or 2 minutes according to cytological final result, and to assess whether the presence of obscuring factors in cervical smear samples affects the frequency of false-negative results. Methods: A total of 5 235 smears classified as negative (93.0%) or unsatisfactory (2.1%) at routine screening were submitted to 100% rapid review using mean times of 1 and 2 minutes. Results: Of the 5 235 smears submitted to 1-minute rapid review, 88 were considered suspect and of these, 45 were confirmed as abnormal in the cytological final result. When the time used was 2 minutes, 67 smears were considered suspect, 44 of which were confirmed as abnormal. Sensitivity and specificity were similar in the 1- and 2-minute reviews. In smears in which samples were satisfactory and had no obscuring factors, sensitivity and specificity were 64.2% and 98.9% and 61.5% and 99.5% for the 1- and 2-minute reviews, respectively. In comparison, in smears in which the sample was satisfactory for analysis but partially obscured (50-75%), sensitivity and specificity were 64.7% and 99.9% and 70.6% and 99.8% for the 1- and 2-minute reviews, respectively. Conclusions: The method of rapid review of 100% showed no difference in the detection of false-negative results using the time of 1 or 2 minutes. The quality of the sample did not influence the detection of false-negatives.223195201Goias Foundation [002/2007]Goias Foundation [002/2007]
