Results of a control quality strategy in cervical cytology.

Objective: To determine the efficacy of a quality control strategy in cervical cytology in the detection of high-grade squamous intraepithelial lesions.

Methods: Forty-two patients were selected who underwent a Pap smear and cervical uterine biopsy between April 2008 and December 2009, with evidence of a high-grade squamous intraepithelial lesion in one or both tests. The statistical parameters of the smear test were calculated before and after systematic meetings for review of the archived test results (6 years), in which the following was done: interobserver diagnostic consensus; cytohistological correlation, with the latter as gold standard; and evaluation of the therapeutic status of each patient.
