[Program of quality control in gynecologic cytology at the Adolfo Lutz Institute: strategies and critical analysis of results of its pilot implementation].
The Quality Control in the Gynecological Cytology Program, Instituto Adolfo Lutz, was designed to assure a high-standard of laboratory analysis for the Gynecological Cancer Detection and Prevention System in the São Paulo State Public Health Service. This study presents strategies for intra-laboratorial quality control as well as preliminary results on 32,018 cases. The methods applied for the selection of cases to be reviewed were based on clinical and cytological conditions that could mean higher risk of development of neoplasia and/or conditions that might induce difficulties of interpretation. The classification and analysis of the discrepancies found in this initial experience are the highlight points of this Program. Out of the 492 cases submitted to review, 45 had received underscored initial interpretation, although none of them fit international criteria for "false-negative". Overscores were found in 51 cases, with only three cases fitting the criteria for "false-positive". Based on this initial experience, the Quality Control Program will be applied to the other laboratories of the Public Health Service. This intra-laboratory model of control will be coupled with external supervision by Instituto Adolfo Lutz.
